Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development. This is supported by pathology findings revealing EBV-infected B cells within CNS lesions and immunogenetic data linking viral and human genetic susceptibility to MS risk. Mechanistically, EBV appears to act as an upstream trigger that reshapes B cell function, promotes molecular mimicry with CNS antigens, and drives compartmentalized neuroinflammation. In this Review, we synthesize epidemiological, pathological, immunogenetic, and clinical-therapeutic evidence to construct a coherent model of EBV-driven MS pathogenesis. We examine how current MS therapies intersect with EBV biology and discuss the challenges and opportunities in developing EBV-targeted strategies, including vaccines and antivirals, for disease prevention and early intervention. Finally, we highlight key unresolved questions and outline a translational research agenda aimed at intercepting MS through virologically informed approaches."

"abstract_text": "ID: 41484491\nTitle: Microglia Mitochondrial Metabolism in Neurological Diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), play critical roles in maintaining brain homeostasis and responding to neurological insults. Recent advances have fundamentally reshaped our understanding of how microglial mitochondrial metabolism influences neuroinflammation and disease progression. Single-cell transcriptomics has revealed unexpected metabolic heterogeneity, identifying distinct phenotypes such as disease-associated microglia (DAM) and lipid-laden microglia (LLM) that represent not merely activated states but terminal endpoints of metabolic paralysis. These discoveries converge on a unified pathogenic mechanism: mitochondrial quality control failure leads to mitochondrial DNA release, which activates the cGAS-STING pathway to create an \"epigenetic lock\" that drives sustained neuroinflammation. Interestingly, we highlight that the loss of metabolic flexibility-rather than glycolysis per se-is the true driver of pathology, explaining why the same metabolic shift can be protective during acute injury but pathological when sustained chronically. We critically examine conflicting evidence across Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ischemic stroke, including the puzzling dual roles of glycolysis, controversies surrounding the experimental autoimmune encephalomyelitis (EAE) model in multiple sclerosis research, and the paradoxical worsening of stroke outcomes following microglial depletion. By synthesizing these mechanistic insights with lessons from failed clinical trials, we identify critical translational gaps-including the lack of longitudinal human data and validated biomarkers-and propose a precision medicine framework focused on restoring mitochondrial dynamics and metabolic flexibility in neurological diseases."

The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self-epitopes in the central nervous system (CNS). This study seeks to explore the common pentapeptides present in EBV and HHV-6 viral antigens alongside various CNS-related proteins via molecular mimicry. Additionally, it will assess the immunogenicity of these shared pentapeptides in T and B cells. Sequence alignment was conducted to assess molecular mimicry between 32 EBV and HHV-6 antigens and 10 CNS autoantigens. Protein sequences were obtained from UniProt, structural homology was analyzed using AlphaFold and PyMol, and shared pentapeptides were identified with Alignmentaj. Immunogenicity was assessed via the Immune Epitope Database (IEDB) for potential T- and B-cell activation. A total of 91 mimicry pentapeptides were identified between viral antigens (42 EBV and 49 human HHV-6), and 10 CNS proteins. Notably, synapsin (SYN)1 exhibited the highest mimicry, sharing 13 pentapeptides with (7 with EBV and 6 with HHV-6) viral antigens such as EBV nuclear antigen (EBNA)1, EBNA6, latent membrane protein (LMP)1, and early antigen diffused (EA-D). Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens. EBNA1, EBNA2, EBNA6, LMP1, LMP2, EA-D, and BLLF1 structurally resemble CNS autoantigens and act as immunoreactive epitopes for human T and B cells. Except for EBNA2 and protein U94, all share immunogenic pentapeptide sequences with SYN1. Shared pentapeptides suggest a link between viral infections and CNS autoimmunity. Further research is needed to clarify molecular mechanisms and explore targeted therapies to mitigate virus-induced neuroinflammation."

While studies have highlighted the distinct roles of microglia and Th17 cells in EAE, it remains unclear whether microglia, as potential professional antigen-presenting cells, activate and stabilize the effector program of EAE-pathogenic Th17 cells in vivo; and if so, whether the Th17 could in turn reinforce the active state of the microglia.

We also captured and identified the molecular properties of the feed-forward loop, which are two-cell entities of microglia-Th17, and proved them as the functional units of antigen presentation and bi-directional activation between the two cell types. Moreover, ACT001, an orphan drug to treat glioblastoma, disrupts this feed-forward activation loop by inhibiting the STING\u2192NF-\u03baB pathway in microglia, thereby alleviating EAE.

Typically occurring in young and middle-aged individuals, untreated MS can have high rates of disability and recurrence, thereby imposing a significant burden on the patient, their family, and society. Many factors are implicated in the etiology of MS, with the relationship between Epstein-Barr Virus (EBV) infection and the development of MS being the subject of extensive research recently. When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS. Currently, the phenomenon of cross-reactivity resulting from molecular mimicry following EBV infection (including reactivation status) is theorized as a contributing etiology. EBV-mediated abnormalities in T cells and B cells also play a key role in the development of MS. However, the underlying mechanisms have not been thoroughly understood. Meanwhile, the limited availability of effective treatment options for MS, in particular MS progression, underscores the urgent need for novel therapeutic strategies. Here, we discuss the pathophysiological mechanisms underlying MS, specifically emphasizing the relationship between EBV infection and the disease pathology. Furthermore, we introduced relevant pharmacological targets in order to propose a broader range of therapeutic alternatives for individuals diagnosed with MS."

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

This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration."

Hongqi Shenmai Yin (HSY) has been used in clinical practice for many years, can improve cardiac function in MI patients. However, its underlying therapeutic mechanisms remain unclear. This study aimed to determine whether HSY alleviates adverse cardiac remodeling following MI by inhibiting stimulator of interferon genes (STING)-dependent PANoptosis. The MI model was established by ligating the left anterior descending coronary artery (LAD) in rats. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS) identified bioactive compounds in HSY. Cardiac function, hypertrophy, and fibrosis were assessed via echocardiography and histological staining. ELISA measured cardiac injury biomarkers, inflammatory cytokines, and oxidative stress markers. Transcriptomic analyses identified potential HSY targets in post-MI remodeling. Molecular docking and surface plasmon resonance (SPR) assessed binding interactions between HSY's key active components and STING. Mechanistic rescue experiments determined whether HSY regulates PANoptosis via STING inhibition. Functional studies were further conducted by transfecting H9c2 cardiomyocytes with lentivirus vectors encoding STING-overexpression. HSY attenuated inflammation, oxidative stress, and adverse remodeling while improving cardiac function post-MI. UPLC-MS identified 107 major HSY constituents. Transcriptomics linked HSY's cardioprotective effects to STING signaling and PANoptosis modulation. Molecular docking and SPR confirmed strong binding affinity between HSY's primary active compounds and STING. Both in vivo and in vitro experiments revealed that HSY suppressed STING-induced ZBP1-PANoptosome assembly, downregulating PANoptosis-associated proteins (p-MLKL, p-RIPK1, p-RIPK3, GSDMD-NT, GSDME-NT, Cle-CASP1, Cle-CASP3, Cle-CASP8) in post-MI remodeling. HSY attenuated adverse cardiac remodeling following MI by inhibiting STING-mediated ZBP1-PANoptosome assembly and subsequent PANoptosis.

Recent studies have demonstrated that oxymatrine inhibits experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), by promoting the production of interferon-\u03b2 (IFN-\u03b2). However, the mechanism through which oxymatrine regulates the production of IFN-\u03b2 remains unclear. The aim of this study was to investigate the pharmacological effects and related molecular mechanisms of oxymatrine in the treatment of EAE through in vivo and in vitro experiments. Oxymatrine alleviated neurological dysfunction, demyelination, and inflammation in EAE mice. It reduced microglia/macrophage infiltration and polarization, lowered pro-inflammatory cytokine levels (iNOS, TNF-\u03b1), and enhanced the expression of IL-10 and IL-27. Additionally, oxymatrine upregulated the STING/TBK1/IRF3 signaling pathway in EAE mice, promoting IFN-\u03b2 production by microglia. Similarly, in LPS-induced BV2 cells, oxymatrine suppressed inflammatory factors and activated the STING/TBK1/IRF3 pathway to enhance IFN-\u03b2 production. Notably, treatment with the STING inhibitor, C176, reversed these effects in both EAE mice and LPS-induced BV2 cells, confirming the pathway's critical role in the mechanism of oxymatrine therapy. Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events. This study identifies a novel anti-EAE mechanism of oxymatrine: promoting IFN-\u03b2 production in microglia by activating the STING/TBK1/IRF3 pathway. However, it lacks clinical sample verification. If validated later, oxymatrine may provide a more economical, convenient endogenous IFN-\u03b2 induction regimen for MS patients."

However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells.

Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis.

Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta.

Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks.

This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.

Antiretroviral and antiviral therapies suppress viral replication but fail to reverse organelle-level dysfunction, leaving most hippocampal injury unaddressed. Emerging plasma biomarkers, p-tau217, neurofilament light chain, and GFAP, combined with hippocampal subfield MRI, now enable mechanistic stratification before irreversible circuit loss occurs. This review proposes, as a unifying hypothesis, that virus-associated memory impairment represents a convergent hippocampal syndrome driven by shared downstream pathways, and that combination therapies targeting these pathways simultaneously offer greater therapeutic promise than pathogen-specific approaches alone. The evidentiary basis for this framework varies across pathogens and conditions; direct mechanistic evidence, mechanistic analogy, and preclinical data are distinguished throughout."

While acute COVID-19 is generally milder in children due to a more robust innate immune response, the mechanisms driving the persistence of symptoms in PPCC remain incompletely understood and likely multifactorial. This narrative review synthesizes current epidemiological data and explores the \"perfect storm\" of immunological and pathophysiological alterations underpinning the condition. We examine critical hypotheses including a dysregulated immune response characterized by altered T-cell subsets, monocyte activation, and autoantibody production. We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in \"sanctuary sites\" like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV). Furthermore, the review details downstream pathogenic pathways, including vascular endothelial inflammation (thrombo-inflammation), neuroinflammation, and metabolic dysfunctions affecting the mitochondria and tryptophan-kynurenine pathway. Finally, we address the role of microbiome dysbiosis in perpetuating systemic inflammation and the gut-lung axis dysfunction. Given the heterogeneity of clinical presentations, we conclude that PPCC is likely a syndrome of overlapping biological phenotypes. Future research must prioritize identifying these specific biological endotypes to develop targeted diagnostic and therapeutic strategies for the pediatric population."

Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development. This is supported by pathology findings revealing EBV-infected B cells within CNS lesions and immunogenetic data linking viral and human genetic susceptibility to MS risk. Mechanistically, EBV appears to act as an upstream trigger that reshapes B cell function, promotes molecular mimicry with CNS antigens, and drives compartmentalized neuroinflammation. In this Review, we synthesize epidemiological, pathological, immunogenetic, and clinical-therapeutic evidence to construct a coherent model of EBV-driven MS pathogenesis. We examine how current MS therapies intersect with EBV biology and discuss the challenges and opportunities in developing EBV-targeted strategies, including vaccines and antivirals, for disease prevention and early intervention.

Typically occurring in young and middle-aged individuals, untreated MS can have high rates of disability and recurrence, thereby imposing a significant burden on the patient, their family, and society. Many factors are implicated in the etiology of MS, with the relationship between Epstein-Barr Virus (EBV) infection and the development of MS being the subject of extensive research recently. When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS. Currently, the phenomenon of cross-reactivity resulting from molecular mimicry following EBV infection (including reactivation status) is theorized as a contributing etiology. EBV-mediated abnormalities in T cells and B cells also play a key role in the development of MS. However, the underlying mechanisms have not been thoroughly understood. Meanwhile, the limited availability of effective treatment options for MS, in particular MS progression, underscores the urgent need for novel therapeutic strategies. Here, we discuss the pathophysiological mechanisms underlying MS, specifically emphasizing the relationship between EBV infection and the disease pathology. Furthermore, we introduced relevant pharmacological targets in order to propose a broader range of therapeutic alternatives for individuals diagnosed with MS."

These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self-epitopes in the central nervous system (CNS). This study seeks to explore the common pentapeptides present in EBV and HHV-6 viral antigens alongside various CNS-related proteins via molecular mimicry. Additionally, it will assess the immunogenicity of these shared pentapeptides in T and B cells. Sequence alignment was conducted to assess molecular mimicry between 32 EBV and HHV-6 antigens and 10 CNS autoantigens. Protein sequences were obtained from UniProt, structural homology was analyzed using AlphaFold and PyMol, and shared pentapeptides were identified with Alignmentaj. Immunogenicity was assessed via the Immune Epitope Database (IEDB) for potential T- and B-cell activation. A total of 91 mimicry pentapeptides were identified between viral antigens (42 EBV and 49 human HHV-6), and 10 CNS proteins. Notably, synapsin (SYN)1 exhibited the highest mimicry, sharing 13 pentapeptides with (7 with EBV and 6 with HHV-6) viral antigens such as EBV nuclear antigen (EBNA)1, EBNA6, latent membrane protein (LMP)1, and early antigen diffused (EA-D). Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens. EBNA1, EBNA2, EBNA6, LMP1, LMP2, EA-D, and BLLF1 structurally resemble CNS autoantigens and act as immunoreactive epitopes for human T and B cells. Except for EBNA2 and protein U94, all share immunogenic pentapeptide sequences with SYN1. Shared pentapeptides suggest a link between viral infections and CNS autoimmunity. Further research is needed to clarify molecular mechanisms and explore targeted therapies to mitigate virus-induced neuroinflammation."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.

Recent studies have demonstrated that oxymatrine inhibits experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), by promoting the production of interferon-\u03b2 (IFN-\u03b2). However, the mechanism through which oxymatrine regulates the production of IFN-\u03b2 remains unclear. The aim of this study was to investigate the pharmacological effects and related molecular mechanisms of oxymatrine in the treatment of EAE through in vivo and in vitro experiments. Oxymatrine alleviated neurological dysfunction, demyelination, and inflammation in EAE mice. It reduced microglia/macrophage infiltration and polarization, lowered pro-inflammatory cytokine levels (iNOS, TNF-\u03b1), and enhanced the expression of IL-10 and IL-27. Additionally, oxymatrine upregulated the STING/TBK1/IRF3 signaling pathway in EAE mice, promoting IFN-\u03b2 production by microglia. Similarly, in LPS-induced BV2 cells, oxymatrine suppressed inflammatory factors and activated the STING/TBK1/IRF3 pathway to enhance IFN-\u03b2 production. Notably, treatment with the STING inhibitor, C176, reversed these effects in both EAE mice and LPS-induced BV2 cells, confirming the pathway's critical role in the mechanism of oxymatrine therapy. Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events. This study identifies a novel anti-EAE mechanism of oxymatrine: promoting IFN-\u03b2 production in microglia by activating the STING/TBK1/IRF3 pathway. However, it lacks clinical sample verification. If validated later, oxymatrine may provide a more economical, convenient endogenous IFN-\u03b2 induction regimen for MS patients."

Prior attempts to treat NMOSD with interferon-beta (IFN-\u03b2), a disease-modifying therapy for multiple sclerosis, resulted in worsening of disease activity, with an unknown mechanism. Here, robust activation of the cGAS-STING-IFN-I signaling pathway is identified\u00a0in myeloid cells in both the periphery and central nervous system. The abnormal IFN-I response gives rise to an increase in the number of AQP4 antigen-specific autoreactive T cells. Sting deficiency can significantly blunt the activation of AQP4-specific T cells, as well as the IFN-I activity in microglia, and attenuate astrocyte damage. Consequently, the clinical manifestation of NMOSD is ameliorated in a passive transfer mouse model of NMOSD. Further, treatment with STING inhibitor H151 alleviates the severity of NMOSD mouse models. These findings uncover the cGAS-STING-IFN-I pathway in promoting autoreactive T cells and establish a foundation for inhibiting this pathway as a new therapeutic revenue for NMOSD."

This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders."

Hongqi Shenmai Yin (HSY) has been used in clinical practice for many years, can improve cardiac function in MI patients. However, its underlying therapeutic mechanisms remain unclear. This study aimed to determine whether HSY alleviates adverse cardiac remodeling following MI by inhibiting stimulator of interferon genes (STING)-dependent PANoptosis. The MI model was established by ligating the left anterior descending coronary artery (LAD) in rats. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS) identified bioactive compounds in HSY. Cardiac function, hypertrophy, and fibrosis were assessed via echocardiography and histological staining. ELISA measured cardiac injury biomarkers, inflammatory cytokines, and oxidative stress markers. Transcriptomic analyses identified potential HSY targets in post-MI remodeling. Molecular docking and surface plasmon resonance (SPR) assessed binding interactions between HSY's key active components and STING. Mechanistic rescue experiments determined whether HSY regulates PANoptosis via STING inhibition. Functional studies were further conducted by transfecting H9c2 cardiomyocytes with lentivirus vectors encoding STING-overexpression. HSY attenuated inflammation, oxidative stress, and adverse remodeling while improving cardiac function post-MI. UPLC-MS identified 107 major HSY constituents. Transcriptomics linked HSY's cardioprotective effects to STING signaling and PANoptosis modulation. Molecular docking and SPR confirmed strong binding affinity between HSY's primary active compounds and STING.

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

This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration."

Immunization with the E743-77 peptide adjuvanted by 2'3'-cGAMP significantly suppressed tumor growth and elicited high levels of Interferon (IFN)-\u03b3 and Granzyme B in CD8+ cytotoxic T lymphocytes. The vaccine also enhanced the differentiation of natural killer (NK) cells, dendritic cells (DCs), and M1-type macrophages, reduced Myeloid-derived suppressor cells (MDSCs), and increased INF-\u03b2 levels, as well as promote lymphocyte infiltration and remodeling in tumor immune microenvironment (TME). Mechanistically, 2'3'-cGAMP promoted DC maturation, enhanced T cell proliferation and activation, and strengthened antigen-specific CTL responses by activating the STING-TBK1-IRF3 and STING-NF-\u03baB pathways in peptide-loaded DCs. The STING agonist 2'3'-cGAMP serves as an effective adjuvant that enhances the therapeutic efficacy of an HPV16 peptide vaccine. These findings indicate its potential as a candidate therapeutic for HPV16 persistent infection and associated malignancies."

Previous studies in mice have shown that stimulating type I interferon (IFN) signaling during BCG vaccination can bolster protection against Mycobacterium tuberculosis , yet clinically feasible delivery strategies for this approach are lacking. Adenoviral vectors, which induce potent type I IFN responses and are utilized in approved vaccine platforms, represent a promising adjuvant strategy. To evaluate the host immune response to this combination, bone marrow-derived murine macrophages were co-infected with replication-deficient adenovirus and BCG. Adenovirus-infected macrophages elicited a robust type I IFN response via the cGAS/STING pathway. Compared to BCG infection alone, co-infected macrophages exhibited additive expression of genes with known host-protective roles against M. tuberculosis . Conversely, co-infection with BCG suppressed adenovirus-induced type I IFN signaling and diminished the production of IFN-stimulated genes compared to adenovirus infection alone. Together, these findings reveal a complex regulatory interplay during adenovirus and BCG co-infection. While BCG partially restricts adenoviral IFN induction, the co-infection still drives an enhanced host-protective gene profile, suggesting that adenoviral vectors could serve as a viable platform to modulate innate immunity and improve BCG vaccine efficacy. Tuberculosis (TB) remains the leading cause of death by a single infectious organism with approximately 1.25 million deaths annually. M. bovis BCG remains the only approved vaccine for TB; however, its efficacy against the contagious and most common pulmonary form of the disease is limited. There have been numerous attempts to improve BCG efficacy, but these approaches have not resulted in any clinically approved vaccine. We propose that BCG combined with a replication-deficient adenovirus presents a way to bolster vaccine-conferred protection as the combination may elicit a robust innate immune response and drive a more protective T cell response. Moreover, BCG and replication-deficient adenoviruses have well-assessed safety profiles and decades of studies regarding their use in patients. The significance of our work is in leveraging their complementary immunology to function as a combined vaccine platform. This approach presents a novel and clinically feasible approach to improve the BCG vaccine."

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

Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks.

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

Its role has expanded from conventional local tumor eradication to active regulation of the tumor immune microenvironment. In recent years, emerging radiotherapy strategies, including FLASH radiotherapy, boron neutron capture therapy, lattice radiotherapy, spatially fractionated radiation therapy, precision particle therapy, immunomodulatory stereotactic body radiotherapy, and immune-optimized carbon ion therapy, have provided new opportunities to improve tumor control, reduce normal tissue toxicity, and overcome radioresistance. Radiotherapy can induce DNA damage and immunogenic cell death, promote tumor antigen release, enhance dendritic cell maturation and antigen cross-presentation, and increase CD8+ T-cell infiltration and antitumor immunity through the cGAS-STING type I interferon pathway. However, radiotherapy may also trigger immunosuppressive feedback, including the accumulation of myeloid-derived suppressor cells, tumor-associated macrophages, and regulatory T cells, as well as the upregulation of immune checkpoint molecules such as programmed death-ligand 1 (PD-L1). These changes may limit antitumor immune responses and contribute to radioresistance. Combining radiotherapy with immune checkpoint inhibitors can amplify antitumor immunity, but therapeutic efficacy is influenced by dose fractionation, treatment timing, tumor type, and baseline immune status. This mini review summarizes emerging radiotherapy strategies and their regulatory effects on the tumor immune microenvironment, and discusses the mechanistic basis, current challenges, and future directions of radiotherapy combined with immunotherapy."

The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development."

In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases."

However, activation of neuronal STING requires its detachment from the stromal interaction molecule 1 (STIM1), a process triggered by glutamate excitotoxicity. This detachment initiates non-canonical STING signaling, which leads to autophagic degradation of glutathione peroxidase 4 (GPX4), essential for neuronal redox homeostasis and thereby inducing ferroptosis. Both genetic and pharmacological interventions that target STING in neurons protect against inflammation-induced neurodegeneration. Our findings position STING as a central regulator of the detrimental neuronal inflammatory stress response, integrating inflammation with glutamate signaling to cause neuronal cell death, and present it as a tractable target for treating neurodegeneration in MS."

Antimicrobial peptides (AMPs) are immunomodulatory molecules expressed in various tissues, including the CNS. Here, we investigated whether the cathelicidin-related AMP (CRAMP) modulated the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We showed that, at an early stage, CNS-recruited neutrophils produced neutrophil extracellular traps (NETs) rich in CRAMP that were required for EAE initiation. NET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response. However, at a later disease stage, neurons also expressed CRAMP that reduced EAE severity. Camp knockdown in neurons led to disease exacerbation, while local injection of CRAMP1-39 at the peak of EAE promoted disease remission. In vitro, CRAMP1-39 regulated the activation of microglia and astrocytes through the formyl peptide receptor (FPR) 2. Finally, administration of butyrate, a gut microbiota-derived metabolite, stimulated the expression of neural CRAMP via the free fatty acids receptors 2/3 (FFAR2/3), and prevented EAE. This study shows that CRAMP produced by different cell types has opposing effects on neuroinflammation, offering therapeutic opportunities for MS and other neuroinflammatory disorders."

EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development."

Data on their prevalence and kinetics in low- and middle-income countries, including Morocco, remain limited. This study aimed to evaluate these infections at the Children's Hospital in Rabat. We conducted a retrospective descriptive study of pediatric patients who underwent HSCT at the Children's Hospital in Rabat from January 2018 to June 2025. Post-transplant viral monitoring included weekly quantitative PCR for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) until day 100. Targeted PCR for adenovirus, BK virus, HHV-6, and respiratory viruses was performed in symptomatic patients. Out of 33 patients, CMV was the most frequently detected agent, with an incidence of 51,5% (n\u2009=\u200917), of which 30.3% had a viral load\u2009>\u20092.5 log\u2081\u2080 IU/ml. The median time to first reactivation was 3\u2009weeks (IQR: 2-6). The vast majority of episodes occurred in seropositive (R+) recipients, mainly D+/R+. The highest viral loads were observed in patients with CMV viremia temporally associated with pulmonary involvement (2.62 log\u2081\u2080 IU/ml [IQR: 0.00-3.42]) compared to those without pulmonary involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04]; p\u2009=\u20090.007), despite the absence of virological confirmation of CMV-related pulmonary disease. Similarly, patients with gastrointestinal (GI) complications had higher viral loads (3.13 log\u2081\u2080 IU/ml [IQR: 2.23-3.89]) compared with those without GI involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04], p\u2009=\u20090.002). Concerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant. Infections were more frequent in recipients who were initially seronegative (D+/R-) included 8 of 13 patients (61.5%), No cases of post-transplant lymphoproliferative disease were reported. BK virus showed an early peak of infection between the 1st and 4th week, strongly associated with the occurrence of hemorrhagic cystitis, highlighting its significant clinical impact during this period. This study highlights the particularly early kinetics of CMV, BK virus, and EBV in our pediatric patients after HSCT, with CMV appearing around week 3, transient EBV reactivations in initially seronegative patients, and an early BK virus peak linked to hemorrhagic cystitis."

To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group) received rituximab (375 mg/m\u00b2) on day -3 before transplantation due to the presence of donor-specific antibody (MFI \u2265 2000) (n = 25) and patients in control group (C group) did not receive rituximab (n = 75) and donor-specific antibody was low (MFI < 2000). The primary objectives were the incidence of EBV-DNA viremia and PTLD within one-year post-transplantation. Secondary objectives included the incidence of CMV infection, cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic GVHD, 100-day non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS). No significant differences were observed in baseline characteristics between the two groups except for primary disease. When compared with the C group, patients in R group exhibited a lower cumulative incidence of EBV viremia within one-year post - transplantation (4.00% vs. 22.67%, P\u00a0=\u00a00.049) and a lower incidence of aGVHD (28% vs. 50.67%, P\u00a0=\u00a00.048). There was a trend toward reduction of PTLD in the R group compared with C group (0% vs. 10.67%, P\u00a0=\u00a00.089).There were no significant differences of the incidence of CMV viremia (24% vs. 13.33%, P\u00a0=\u00a00.208), cGVHD (16% vs. 12%, P\u00a0=\u00a00.607), and 100 - day NRM (4.0% vs. 10.67%, P\u00a0=\u00a00.313) between two groups.

"abstract_text": "ID: 42384430\nTitle: Viruses, Periodontitis, and Systemic Diseases.\nAbstract: Viruses are increasingly recognized as potential modulators of oral biofilm ecology and periodontal inflammation, expanding the traditional bacterial paradigm of periodontitis. Members of the Herpesviridae family, including Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus (HSV), are frequently detected in periodontal tissues and may influence disease activity through latency, reactivation, immune modulation, epithelial barrier disruption, and interactions with bacteria. These processes may contribute to local dysbiosis and sustained periodontal inflammation. The potential systemic relevance of oral viruses is biologically plausible but remains incompletely established. Viral persistence or reactivation in oral niches may contribute to systemic immune activation through hematogenous spread, saliva-mediated dissemination, aspiration, or amplification of inflammatory mediators as IL-1\u03b2, IL-6, and TNF-\u03b1. Accordingly, viruses may act as disease modifiers within the broader relationship between periodontitis and systemic conditions including cardiovascular, metabolic, respiratory, neurogenerative, pregnancy-related, and cancer-associated outcomes. However, the strength of evidence differs across these conditions. Current data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden. Nevertheless, most available evidence is observational, associative, or derived from mechanistic experimental models, and definitive proof that viruses are independent etiopathogenic drivers of periodontitis is lacking. Future longitudinal and interventional studies are needed to determine whether viral detection reflects bystander association, disease amplification, or a true pathogenic role, and whether antiviral or phage-based strategies offer clinical benefit beyond established periodontal therapy."

From a mechanistic standpoint, our previous work explained this genetic association by defining an immunomodulatory function for ataxin-1 in controlling specific genetic programs underlying B cell proliferation, activation, immunoglobulin production, and antigen presentation. Here, we employed a high-resolution multiomics analytical pipeline to further dissect the role of ataxin-1 in distinct B cell subsets upon encephalitogenic stress. By combining single-nuclei RNA-seq and ATAC-seq, along with mass-spectrometry proteomics, we documented that ataxin-1 is significantly enriched in B1 cells, marginal zone B cells, memory B cells, and precursor B cells. Pathway analysis highlighted that ataxin-1 is implicated in RNA splicing and translation processes. Conversely, no major effects were implicated for ataxin-1 in chromatin remodeling in the B cell population. Our findings expand the current knowledge of the cellular functions controlled by ataxin-1 outside of the central nervous system, and further describe a key regulator of B cell biology in health and disease."

These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

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

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

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

One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved.

Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus.

In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases."

The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development."

By dissecting the neuronal inflammatory stress response, we discovered that neurons in MS and its mouse model induce the stimulator of interferon genes (STING). However, activation of neuronal STING requires its detachment from the stromal interaction molecule 1 (STIM1), a process triggered by glutamate excitotoxicity. This detachment initiates non-canonical STING signaling, which leads to autophagic degradation of glutathione peroxidase 4 (GPX4), essential for neuronal redox homeostasis and thereby inducing ferroptosis. Both genetic and pharmacological interventions that target STING in neurons protect against inflammation-induced neurodegeneration. Our findings position STING as a central regulator of the detrimental neuronal inflammatory stress response, integrating inflammation with glutamate signaling to cause neuronal cell death, and present it as a tractable target for treating neurodegeneration in MS."

Antimicrobial peptides (AMPs) are immunomodulatory molecules expressed in various tissues, including the CNS. Here, we investigated whether the cathelicidin-related AMP (CRAMP) modulated the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We showed that, at an early stage, CNS-recruited neutrophils produced neutrophil extracellular traps (NETs) rich in CRAMP that were required for EAE initiation. NET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response. However, at a later disease stage, neurons also expressed CRAMP that reduced EAE severity. Camp knockdown in neurons led to disease exacerbation, while local injection of CRAMP1-39 at the peak of EAE promoted disease remission. In vitro, CRAMP1-39 regulated the activation of microglia and astrocytes through the formyl peptide receptor (FPR) 2. Finally, administration of butyrate, a gut microbiota-derived metabolite, stimulated the expression of neural CRAMP via the free fatty acids receptors 2/3 (FFAR2/3), and prevented EAE. This study shows that CRAMP produced by different cell types has opposing effects on neuroinflammation, offering therapeutic opportunities for MS and other neuroinflammatory disorders."

Data on their prevalence and kinetics in low- and middle-income countries, including Morocco, remain limited. This study aimed to evaluate these infections at the Children's Hospital in Rabat. We conducted a retrospective descriptive study of pediatric patients who underwent HSCT at the Children's Hospital in Rabat from January 2018 to June 2025. Post-transplant viral monitoring included weekly quantitative PCR for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) until day 100. Targeted PCR for adenovirus, BK virus, HHV-6, and respiratory viruses was performed in symptomatic patients. Out of 33 patients, CMV was the most frequently detected agent, with an incidence of 51,5% (n\u2009=\u200917), of which 30.3% had a viral load\u2009>\u20092.5 log\u2081\u2080 IU/ml. The median time to first reactivation was 3\u2009weeks (IQR: 2-6). The vast majority of episodes occurred in seropositive (R+) recipients, mainly D+/R+. The highest viral loads were observed in patients with CMV viremia temporally associated with pulmonary involvement (2.62 log\u2081\u2080 IU/ml [IQR: 0.00-3.42]) compared to those without pulmonary involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04]; p\u2009=\u20090.007), despite the absence of virological confirmation of CMV-related pulmonary disease. Similarly, patients with gastrointestinal (GI) complications had higher viral loads (3.13 log\u2081\u2080 IU/ml [IQR: 2.23-3.89]) compared with those without GI involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04], p\u2009=\u20090.002). Concerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant. Infections were more frequent in recipients who were initially seronegative (D+/R-) included 8 of 13 patients (61.5%), No cases of post-transplant lymphoproliferative disease were reported. BK virus showed an early peak of infection between the 1st and 4th week, strongly associated with the occurrence of hemorrhagic cystitis, highlighting its significant clinical impact during this period. This study highlights the particularly early kinetics of CMV, BK virus, and EBV in our pediatric patients after HSCT, with CMV appearing around week 3, transient EBV reactivations in initially seronegative patients, and an early BK virus peak linked to hemorrhagic cystitis."

To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group) received rituximab (375 mg/m\u00b2) on day -3 before transplantation due to the presence of donor-specific antibody (MFI \u2265 2000) (n = 25) and patients in control group (C group) did not receive rituximab (n = 75) and donor-specific antibody was low (MFI < 2000). The primary objectives were the incidence of EBV-DNA viremia and PTLD within one-year post-transplantation. Secondary objectives included the incidence of CMV infection, cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic GVHD, 100-day non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS). No significant differences were observed in baseline characteristics between the two groups except for primary disease. When compared with the C group, patients in R group exhibited a lower cumulative incidence of EBV viremia within one-year post - transplantation (4.00% vs. 22.67%, P\u00a0=\u00a00.049) and a lower incidence of aGVHD (28% vs. 50.67%, P\u00a0=\u00a00.048).

Members of the Herpesviridae family, including Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus (HSV), are frequently detected in periodontal tissues and may influence disease activity through latency, reactivation, immune modulation, epithelial barrier disruption, and interactions with bacteria. These processes may contribute to local dysbiosis and sustained periodontal inflammation. The potential systemic relevance of oral viruses is biologically plausible but remains incompletely established. Viral persistence or reactivation in oral niches may contribute to systemic immune activation through hematogenous spread, saliva-mediated dissemination, aspiration, or amplification of inflammatory mediators as IL-1\u03b2, IL-6, and TNF-\u03b1. Accordingly, viruses may act as disease modifiers within the broader relationship between periodontitis and systemic conditions including cardiovascular, metabolic, respiratory, neurogenerative, pregnancy-related, and cancer-associated outcomes. However, the strength of evidence differs across these conditions. Current data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden. Nevertheless, most available evidence is observational, associative, or derived from mechanistic experimental models, and definitive proof that viruses are independent etiopathogenic drivers of periodontitis is lacking. Future longitudinal and interventional studies are needed to determine whether viral detection reflects bystander association, disease amplification, or a true pathogenic role, and whether antiviral or phage-based strategies offer clinical benefit beyond established periodontal therapy."

From a mechanistic standpoint, our previous work explained this genetic association by defining an immunomodulatory function for ataxin-1 in controlling specific genetic programs underlying B cell proliferation, activation, immunoglobulin production, and antigen presentation. Here, we employed a high-resolution multiomics analytical pipeline to further dissect the role of ataxin-1 in distinct B cell subsets upon encephalitogenic stress. By combining single-nuclei RNA-seq and ATAC-seq, along with mass-spectrometry proteomics, we documented that ataxin-1 is significantly enriched in B1 cells, marginal zone B cells, memory B cells, and precursor B cells. Pathway analysis highlighted that ataxin-1 is implicated in RNA splicing and translation processes. Conversely, no major effects were implicated for ataxin-1 in chromatin remodeling in the B cell population. Our findings expand the current knowledge of the cellular functions controlled by ataxin-1 outside of the central nervous system, and further describe a key regulator of B cell biology in health and disease."

These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

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

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

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

We performed an integrated multiomic characterization of small extracellular vesicles (sEVs) released from spontaneous lymphoblastoid cell lines (SLCLs) derived from healthy donors and patients with MS, transformed ex vivo by endogenous wild-type EBV. Proteomics identified over 6,000 shared proteins enriched in nucleic acid-binding and chromatin-associated factors. EV-associated DNA resolved into two structurally distinct compartments: DNase-sensitive, high-molecular weight DNA associated with the vesicle corona and DNase-resistant, nucleosome-sized (\u223c130-150 bp) DNA. Both compartments were overwhelmingly host-derived and broadly genomically distributed, whereas EBV DNA was minimal. In contrast, viral RNA cargo was dominated by the EBV noncoding RNA EBER1, which was strikingly enriched across all lines and confirmed within individual vesicles by ddPCR and super-resolution microscopy. EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency, pointing to EV-mediated export of EBER1 as a candidate mechanism linking peripheral EBV infection to distal tissue signaling in MS and beyond."

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."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

Here, we identify the histone acetyltransferase KAT7 (HBO1) as a central epigenetic regulator that links chromatin remodeling to mitochondrial immune activation. KAT7 and its histone mark H3K14ac are elevated in microglia from 5\u00d7FAD mice and human AD brains. Integrative transcriptomic and epigenomic analyses reveal that KAT7 activates transcription of cytidine/uridine monophosphate kinase 2 (Cmpk2), a mitochondrial kinase essential for mtDNA synthesis. Loss of KAT7 reduces Cmpk2 expression, impairs mtDNA replication and release, and consequently suppresses cyclic guanosine monophosphate-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NLRP3 signaling. Importantly, both microglia-specific deletion and pharmacological inhibition of KAT7 mitigate cytosolic mtDNA-induced neuroinflammation, decrease \u03b2-amyloid burden, restore synaptic plasticity, and improve cognitive function in 5\u00d7FAD mice. Together, these findings uncover an epigenetic-mitochondrial axis sustaining microglial pathogenicity and establish KAT7 as a potential therapeutic target for AD."

The Global Burden of Disease Study estimated that more than 10 million individuals were affected in 2020, a figure projected to double by 2040. Pathologically, PD is characterised by the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). Although early mechanistic work centred on gross anatomical changes and neuronal injury, converging evidence now positions neuroinflammation as an early and causal driver of DA neurodegeneration across the entire PD continuum. While cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING)-dependent innate immune signaling has been implicated in several neurodegenerative disorders, its contribution to PD has remained undefined. Here, using complementary in vitro and in vivo PD models, we demonstrate that mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction. Genetic knockdown of STING markedly attenuated DA neuronal demise and preserved motor performance, identifying STING-mediated neuroinflammation as a critical mediator of DAergic neurodegeneration in MPTP-induced motor deficits. Collectively, our data indicate that selective inhibition of the cGAS-STING inflammatory cascade robustly mitigates MPTP-induced nigrostriatal DA neurodegeneration and motor deficits in mice, and nominate this pathway as a tractable therapeutic target for disease-modifying intervention in PD."

The cGAS-STING pathway, a central cytosolic DNA-sensing mechanism essential for antiviral defense, antitumor immunity, and inflammatory regulation, is profoundly influenced by the metabolic milieu. However, the precise role of lactylation in modulating this pathway remains to be systematically synthesized. This review aims to comprehensively analyze the molecular mechanisms by which lysine lactylation regulates the cGAS-STING signaling axis, and to discuss the pathophysiological implications and therapeutic potential of targeting this modification in diseases ranging from autoimmunity and neuroinflammation to cancer. A comprehensive review of the relevant literature was conducted to summarize the biochemical basis of lactylation (including writers, erasers, and readers) and to systematically examine emerging evidence demonstrating direct and indirect regulation of cGAS-STING components by lactylation. Studies involving site-specific modifications, disease models, and therapeutic interventions were collated and analyzed. Lactylation directly targets core pathway components-cGAS at residues such as K21, K131, K156, K162, K275, and K409, and STING-altering their stability, enzymatic activity, DNA-binding capacity, phase separation, and downstream signaling outputs. Depending on context, lactylation exerts dual effects: it stabilizes cGAS and amplifies type I interferon responses in autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis) and hypoxic-ischemic encephalopathy, but promotes cGAS degradation or suppresses STING activity in cancer (lung adenocarcinoma, glioblastoma) and neuropathic pain, thereby facilitating immune evasion or pain sensitization. Indirectly, lactylation modulates cytosolic DNA ligand availability by influencing mitochondrial DNA release (via HMGB1, VDAC1, Arg1, DRP1) or DNA repair (via KU70). The discovery of specific lactyltransferases (AARS1/2, p300) and delactylases (SIRT1-3, HDAC1-3) establishes lactylation as a dynamic, enzymatically controlled process. Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner. Targeting the lactylation regulatory axis-by inhibiting pathogenic lactylation to restore anti-tumor immunity or enhancing it to dampen deleterious inflammation-offers a novel immunometabolic therapeutic strategy for autoimmune disorders, chronic infections, neurodegeneration, and cancer."

Effective immunity therefore depends on precise regulatory control that restrains cGAS/STING activity under homeostatic conditions while preserving the capacity for swift and robust responses to diverse danger signals. In this Review, we synthesize emerging principles that regulate cGAS/STING signaling across cellular contexts to control signal initiation, amplification, and termination. We discuss how disruption, persistence, or pathological rewiring of these regulatory processes contributes to immune imbalance across health and disease, promoting chronic inflammation, immunosuppression, and tissue pathology, with particular relevance to tumor progression and therapeutic resistance. Finally, we consider how restoring appropriate cGAS/STING regulation, rather than simply enhancing or inhibiting pathway activity, may reestablish immune homeostasis and improve therapeutic outcomes in cancer and other inflammatory diseases, framing the pathway as a dynamic regulatory circuit rather than a simple linear signaling cascade."

This study sought to determine whether cGAS-STING-mediated microglial activation and aberrant synaptic pruning underlie sevoflurane-induced cognitive deficits and to assess how environmental conditions modulate these processes. Neonatal mice underwent sevoflurane exposure followed by rearing in enriched (EE) or impoverished (IE) environments. Cognitive function, synaptic structure, microglial activity, mitochondrial status, and cGAS-STING signaling were evaluated using behavioral tests, immunostaining, biochemical assays, and pharmacological inhibition. Sevoflurane exposure induced cognitive impairment, microglial overactivation, mitochondrial dysfunction, and excessive synaptic pruning resulting from microglial overactivation. EE mitigated these abnormalities by preserving mitochondrial integrity and reducing mtDNA-driven cGAS-STING activation, thereby preventing the microglia-mediated imbalance in synaptic pruning and improving cognitive outcomes. In contrast, IE exacerbated mitochondrial injury, aggravated synaptic loss, and further worsened cognitive impairment. Sevoflurane disrupts neurodevelopment through a mitochondria-cGAS-microglia-synapse pathway. Environmental enrichment offers significant neuroprotection, highlighting both cGAS-STING signaling and early-life environmental modulation as promising targets for preventing anesthesia-related neurodevelopmental injury."

The hallmarks of the disease are amyloid plaque accumulation, microglia and astrocyte activation, and loss of presynaptic structure leading to cognitive decline. Recently, oligodendrocyte (OL) and myelin abnormalities have emerged as important contributors to the pathogenesis of AD. In normal brain homeostatic conditions, OL maintain neuronal health through myelin axon interactions and by supplying neurotrophic and metabolic support. How strengthening OL function may support neuronal health in AD neurodegeneration remains to be fully characterized and represents a gap in knowledge and a missed therapeutic opportunity. This study sought to examine how myelin and OL may improve neuronal deficits associated with AD. We have generated a novel mouse model (AD/cKO) by crossing the AppNL-G-F mouse, an established AD model, which carries three human AD mutations in the mouse App gene, with the FusOLcKO whose OL depleted of Fus (Fused in Sarcoma) produce thicker myelin associated with greater cholesterol biosynthesis. We evaluated spatial memory function with standardized cognitive testing. We evaluated microglia density and state, astrocytic activation and toxic phenotype, myelin density, cholesterol content, amyloid plaque burden, presynaptic structures, and neuronal hypoxic and oxidative damage in the hippocampus and cortex. We characterized the transcriptome of AD/cKO hippocampal OL compared to AD by using single-cell transcriptomic studies. Spatial working memory was fully preserved in the aged AD/cKO mouse relative to the AD mouse. This outcome was associated with reduced neuronal oxidative damage, preserved presynaptic structures at the amyloid plaque niches, and a shift in microglia state at the niches in both hippocampus and cortex. In contrast, amyloid plaque burden and microglia density were decreased in the hippocampus but not in cortex, uncoupling the neuronal and microglia effects from the amyloid burden. Fus dependent myelin increase was present in both hippocampus and cortex. Single-cell transcriptomics of AD/cKO hippocampal OL revealed upregulation of energy metabolism and antioxidant genes, suggesting a role of OL enhanced energy metabolism in mediating protection of neurons and affecting microglia state in AD pathology. This work provides new insight into how oligodendrocytes may protect neurons in AD, communicate with other glial cellular players, and point to potential targets for disease intervention aimed at slowing AD progression."

In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair."

This study investigates the mechanisms underlying PDN and aims to identify potential molecular treatment targets. Male C57BL/6\u00a0J wild-type mice were employed to establish a PDN model, receiving intrathecal administration of shRNA targeting Galectin-3 (sh-Gal-3), shRNA targeting YTHDF1 (sh-YTHDF1), a YTHDF1 overexpression vector, or the m6A inhibitor 3-deazaadenosine (3-DAA), either individually or in combination. Macrophages underwent gene knockdown or overexpression and/or treatment with the glycolysis inhibitor 2-deoxy-d-glucose (2-DG) or 3-DAA. Diabetes was confirmed by monitoring blood glucose levels. Pain behavior was evaluated using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) assessments. Expression levels of Gal-3 and YTHDF1 were analyzed via Real-time PCR and Western blot, while myelin phagocytosis was evaluated through immunofluorescence and/or transmission electron microscopy. Glycolysis was assessed by measuring glucose uptake, lactate production, extracellular acidification rate (ECAR), and oxygen consumption rate (OCR). The RNA pull-down assay facilitated the detection of YTHDF1 binding to Gal-3 mRNA, and the half-life of Gal-3 mRNA was measured following transcription blockade using actinomycin D. Additionally, meRIP-qPCR assessed the m6A modification on Gal-3 mRNA. In vivo analyses revealed upregulation of Gal-3, which colocalized with IBA1. Silencing Gal-3 alleviated mechanical allodynia and diminished myelin phagocytosis. In vitro, Gal-3 silencing inhibited glycolysis, while Gal-3 overexpression enhanced myelin phagocytosis, an effect reversed by 2-DG treatment. Furthermore, high glucose stimulation elevated YTHDF1 expression, subsequently increasing Gal-3 levels; this induction was abrogated by YTHDF1 knockdown. Mechanistically, YTHDF1 enhanced Gal-3 mRNA stability through an m6A-dependent mechanism, promoting glycolysis and myelin phagocytosis. Consistently, YTHDF1 overexpression exacerbated PDN symptoms and myelin phagocytosis in vivo, which were mitigated by YTHDF1 knockdown or 3-DAA administration.

Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention."

Didymin has shown neuroprotective effects in intracerebral hemorrhage; however, its regulatory role in SAH remains unclear. The rat SAH model was established using the internal carotid artery puncture method, while an in vitro model was developed by stimulating human brain microvascular endothelial cells (HBMECs) with hemoglobin (Hb). Following didymin treatment, neurological functional outcomes were assessed using the modified Garcia score and the balance beam test. Nissl staining was performed to evaluate neuronal pathological changes. Immunofluorescence staining was employed to assess microglial activation and BBB integrity. Brain water content was measured to evaluate the severity of cerebral edema. Western blot analysis was utilized to detect the expression of matrix metalloproteinase 9 (MMP9), apoptosis-related proteins (Bcl-XL, Bcl-2, Bax), pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and tight junction proteins (ZO-1, Occludin). Didymin treatment significantly improved neurological function scores in SAH rats by alleviating neuronal damage and apoptosis. On one hand, didymin reduced post-SAH neuroinflammation by inhibiting excessive microglial activation and the expression of pro-inflammatory cytokines. On the other hand, didymin preserved BBB integrity and alleviated brain edema by downregulating MMP9 expression. In Hb-induced cell model, didymin suppressed MMP9 expression and promoted the expression of tight junction proteins. In this study, we demonstrated that didymin mitigates neuronal damage and apoptosis following SAH, effectively suppresses neuroinflammation, maintains the integrity of the BBB, and attenuates brain edema.

Tunneling nanotubes (TNTs) are dynamic F-actin-based intercellular connections which transfer mitochondria and pathogenic factors. Although TNTs have been implicated in various neuropathological conditions, their precise involvement in CM pathogenesis, particularly in relation to microglial activation, remains undefined. In this study, single-cell RNA-sequencing (scRNA-seq) revealed significant dysregulation of TNT-associated genes and actin cytoskeleton pathway remodeling in microglia of ECM model. In vitro studies demonstrated that Plasmodium-infected red blood cells (pRBCs)-stimulated primary microglia formed extensive F-actin-rich tunneling nanotubes, which mediated the bidirectional transfer for mitochondria and facilitated intercellular trafficking of lysosomal contents and malarial pigment. These TNT-mediated intercellular communication amplified microglial activation, as evidenced by: (i) lipid peroxidation, (ii) mitochondrial dysfunction, and (iii) autophagosome (LC3+) accumulation. This process further amplifies neuroinflammation through TNF\u03b1/IL-6 secretion and expansion of CD45high microglial populations. Pharmacological TNT inhibition restores microglial homeostasis in ECM model. In conclusion, TNTs mediate neuroinflammation in the ECM model by transferring mitochondria and malarial pigment between microglia. Although mitochondrial transfer may transiently support cellular homeostasis, progressive malarial pigment accumulation triggers lipid metabolism dysregulation and amplified neuroinflammation. Inhibiting TNTs formation attenuates microglial hyperactivation, highlighting targeted regulation of TNT-mediated intercellular communication as a potential therapeutic approach for CM-associated neuropathology."

To date, the precise molecular mechanisms remain incompletely understood. Herein, we showed that DON triggers neurotoxicity by reprogramming microglial glycolysis via activation of the NQO1/NF-\u03baB pathway. Raffinose (Raf), a natural trisaccharide, effectively attenuated DON-induced neuroinflammation in vivo and in vitro. Mechanistically, Raf upregulated NQO1 transcription by selectively binding to Nrf2 at Val-514 and Cys-368, thereby reinforcing the NQO1-I\u03baB\u03b1 interaction, possibly through NQO1-associated regulatory interfaces. This interaction inhibited NF-\u03baB hyperactivation, suppressed glycolysis, and restored oxidative phosphorylation, thereby attenuating DON-induced pro-inflammatory microglial activation. Furthermore, NQO1 knockdown or Nrf2 knockout weakened the inhibitory effect of Raf on the NF-\u03baB signaling pathway and inflammatory activation state of microglia. In conclusion, our findings revealed that Raf supplementation could efficiently alleviate DON exposure-induced neuroinflammation and neurobehavioral deficits by modulating NQO1/NF-\u03baB-associated metabolic remodeling.

Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

A rapidly accumulating body of evidence has not simply challenged the long-dominant monoamine deficiency hypothesis but has provided a mechanistic framework that may explain many of the observed monoaminergic alterations in depressive cohorts, including IDO1-driven serotonin depletion, cytokine-mediated AMPA receptor internalization, and HPA-immune feedback dysregulation. Neuroinflammation, particularly glial activation across microglial, astrocytic, and oligodendrocyte lineages, and its downstream consequences for tryptophan metabolism, glutamatergic transmission, synaptic plasticity, and neurotrophic signaling, represents a central pathophysiological mechanism in a substantial subgroup of depressed patients. Peripheral inflammatory markers, including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha, are elevated in a significant proportion of individuals with major depressive disorder, and these elevations predict poor response to conventional antidepressants while identifying patients who may respond preferentially to anti-inflammatory strategies. Post-mortem studies, positron emission tomography imaging of translocator protein density, and transcriptomic analyses of brain tissue have collectively provided consistent, though not yet fully definitive, evidence that microglial activation is a neurobiological feature of depression rather than a consequence of comorbid physical illness. This review synthesizes current mechanistic understanding of the neuroinflammatory hypothesis of depression, examines the evidence base from epidemiological, biomarker, neuroimaging, and interventional studies, including null findings and methodological limitations, evaluates emerging therapeutic strategies targeting the immune-brain interface, and identifies the critical questions that will determine whether immunopsychiatry fulfills its promise as a precision medicine framework for treatment-resistant depression."

This inflammatory process unfolds years before clinical symptoms, creating an opportunity for early intervention. In vivo imaging technologies that could detect and quantify microglial reactivity are therefore essential for early diagnosis, patient stratification, and evaluating emerging immunomodulatory therapies that target this fundamental driver of PD progression. Yet no standardized, sensitive, and specific technology currently achieves this goal. Molecular magnetic resonance imaging (mMRI) is uniquely suitable to address this problem because it integrates inherent high spatial resolution and soft-tissue contrast of conventional MRI with molecularly targeted contrast agents, enabling simultaneous acquisition of anatomical detail and functional/biological information at submillimeter isotropic resolution. Here we present a novel mMRI probe designed to specifically target colony stimulating factor-1 receptor, expressed primarily on microglia in the brain. In silico data show that the targeting ligand binds the extracellular Ig domain of the receptor. In vitro cell uptake studies with both murine and human microglia cell lines show that the probe binds the receptor triggering active cell uptake and in vivo MRI enabled effective separation of the A53T mouse model of Parkinson's disease from control mice using radiomics-assisted MR image analysis. Ex-vivo immunohistochemical analysis showed signal from the probe largely in the cytosolic compartment of IBA-1 reactive cells, confirming that the observed in vivo MRI signal is due primarily to retention of the agent by microglia. This novel technology has the potential to interrogate the rgional presentation of microglial activation in PD. A microglia targeted MRI probe generates disease-specific contrast after injection, clearly distinguishing A53T Parkinsonian mice from controls."

Microglial M1 polarization and changes in mitochondrial metabolism are crucial in hypoxic brain injury. The cold-inducible RNA-binding protein (CIRBP) is known to regulate mitochondrial balance and inflammatory responses. However, its role in hypoxia-induced microglial metabolic changes, polarization issues, and anxiety-like behaviors is still unclear. This study established an in vivo mouse model of high-altitude hypoxia, an in vitro hypoxic injury model of BV2 microglia, and an in vitro neuronal intervention model with microglia-derived conditioned medium. Integrating in vivo and in vitro experimental designs, we further systematically elucidated the potential molecular mechanisms underlying hypoxic brain injury. Findings indicated that high-altitude hypoxic exposure led to anxiety-like behaviors, social dysfunction, and neuronal and synaptic damage in the hippocampal CA1 region of mice. Hypoxia first triggered mitochondrial metabolic reprogramming in microglia, characterized by inhibition of oxidative phosphorylation, decreased ATP production, and accumulation of reactive oxygen species (ROS) and lactate, which subsequently drove the conversion to the M1 pro-inflammatory phenotype. Inhibition of microglial activation by minocycline significantly reversed hypoxia-induced synaptic damage. At the molecular level, hypoxia downregulated CIRBP expression in microglia. Overexpression of CIRBP in microglia ameliorated mitochondrial metabolic dysfunction and regulated microglial polarization, while knockdown of CIRBP in microglia exacerbated these abnormalities. Targeted overexpression of CIRBP in microglia within the hippocampal CA1 region significantly attenuated hypoxia-induced neuronal damage and behavioral abnormalities. This study elucidates a novel mechanism by which CIRBP in microglia mediates hypoxic brain injury, offering a potential therapeutic target for neuropsychiatric disorders associated with high-altitude hypoxia."

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."

The Global Burden of Disease Study estimated that more than 10 million individuals were affected in 2020, a figure projected to double by 2040. Pathologically, PD is characterised by the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). Although early mechanistic work centred on gross anatomical changes and neuronal injury, converging evidence now positions neuroinflammation as an early and causal driver of DA neurodegeneration across the entire PD continuum. While cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING)-dependent innate immune signaling has been implicated in several neurodegenerative disorders, its contribution to PD has remained undefined. Here, using complementary in vitro and in vivo PD models, we demonstrate that mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction. Genetic knockdown of STING markedly attenuated DA neuronal demise and preserved motor performance, identifying STING-mediated neuroinflammation as a critical mediator of DAergic neurodegeneration in MPTP-induced motor deficits. Collectively, our data indicate that selective inhibition of the cGAS-STING inflammatory cascade robustly mitigates MPTP-induced nigrostriatal DA neurodegeneration and motor deficits in mice, and nominate this pathway as a tractable therapeutic target for disease-modifying intervention in PD."

We performed an integrated multiomic characterization of small extracellular vesicles (sEVs) released from spontaneous lymphoblastoid cell lines (SLCLs) derived from healthy donors and patients with MS, transformed ex vivo by endogenous wild-type EBV. Proteomics identified over 6,000 shared proteins enriched in nucleic acid-binding and chromatin-associated factors. EV-associated DNA resolved into two structurally distinct compartments: DNase-sensitive, high-molecular weight DNA associated with the vesicle corona and DNase-resistant, nucleosome-sized (\u223c130-150 bp) DNA. Both compartments were overwhelmingly host-derived and broadly genomically distributed, whereas EBV DNA was minimal. In contrast, viral RNA cargo was dominated by the EBV noncoding RNA EBER1, which was strikingly enriched across all lines and confirmed within individual vesicles by ddPCR and super-resolution microscopy. EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained.

The cGAS-STING pathway, a central cytosolic DNA-sensing mechanism essential for antiviral defense, antitumor immunity, and inflammatory regulation, is profoundly influenced by the metabolic milieu. However, the precise role of lactylation in modulating this pathway remains to be systematically synthesized. This review aims to comprehensively analyze the molecular mechanisms by which lysine lactylation regulates the cGAS-STING signaling axis, and to discuss the pathophysiological implications and therapeutic potential of targeting this modification in diseases ranging from autoimmunity and neuroinflammation to cancer. A comprehensive review of the relevant literature was conducted to summarize the biochemical basis of lactylation (including writers, erasers, and readers) and to systematically examine emerging evidence demonstrating direct and indirect regulation of cGAS-STING components by lactylation. Studies involving site-specific modifications, disease models, and therapeutic interventions were collated and analyzed. Lactylation directly targets core pathway components-cGAS at residues such as K21, K131, K156, K162, K275, and K409, and STING-altering their stability, enzymatic activity, DNA-binding capacity, phase separation, and downstream signaling outputs. Depending on context, lactylation exerts dual effects: it stabilizes cGAS and amplifies type I interferon responses in autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis) and hypoxic-ischemic encephalopathy, but promotes cGAS degradation or suppresses STING activity in cancer (lung adenocarcinoma, glioblastoma) and neuropathic pain, thereby facilitating immune evasion or pain sensitization. Indirectly, lactylation modulates cytosolic DNA ligand availability by influencing mitochondrial DNA release (via HMGB1, VDAC1, Arg1, DRP1) or DNA repair (via KU70). The discovery of specific lactyltransferases (AARS1/2, p300) and delactylases (SIRT1-3, HDAC1-3) establishes lactylation as a dynamic, enzymatically controlled process. Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner. Targeting the lactylation regulatory axis-by inhibiting pathogenic lactylation to restore anti-tumor immunity or enhancing it to dampen deleterious inflammation-offers a novel immunometabolic therapeutic strategy for autoimmune disorders, chronic infections, neurodegeneration, and cancer."

Effective immunity therefore depends on precise regulatory control that restrains cGAS/STING activity under homeostatic conditions while preserving the capacity for swift and robust responses to diverse danger signals. In this Review, we synthesize emerging principles that regulate cGAS/STING signaling across cellular contexts to control signal initiation, amplification, and termination. We discuss how disruption, persistence, or pathological rewiring of these regulatory processes contributes to immune imbalance across health and disease, promoting chronic inflammation, immunosuppression, and tissue pathology, with particular relevance to tumor progression and therapeutic resistance. Finally, we consider how restoring appropriate cGAS/STING regulation, rather than simply enhancing or inhibiting pathway activity, may reestablish immune homeostasis and improve therapeutic outcomes in cancer and other inflammatory diseases, framing the pathway as a dynamic regulatory circuit rather than a simple linear signaling cascade."

Here, we identify the histone acetyltransferase KAT7 (HBO1) as a central epigenetic regulator that links chromatin remodeling to mitochondrial immune activation. KAT7 and its histone mark H3K14ac are elevated in microglia from 5\u00d7FAD mice and human AD brains. Integrative transcriptomic and epigenomic analyses reveal that KAT7 activates transcription of cytidine/uridine monophosphate kinase 2 (Cmpk2), a mitochondrial kinase essential for mtDNA synthesis. Loss of KAT7 reduces Cmpk2 expression, impairs mtDNA replication and release, and consequently suppresses cyclic guanosine monophosphate-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NLRP3 signaling. Importantly, both microglia-specific deletion and pharmacological inhibition of KAT7 mitigate cytosolic mtDNA-induced neuroinflammation, decrease \u03b2-amyloid burden, restore synaptic plasticity, and improve cognitive function in 5\u00d7FAD mice. Together, these findings uncover an epigenetic-mitochondrial axis sustaining microglial pathogenicity and establish KAT7 as a potential therapeutic target for AD."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

This study sought to determine whether cGAS-STING-mediated microglial activation and aberrant synaptic pruning underlie sevoflurane-induced cognitive deficits and to assess how environmental conditions modulate these processes. Neonatal mice underwent sevoflurane exposure followed by rearing in enriched (EE) or impoverished (IE) environments. Cognitive function, synaptic structure, microglial activity, mitochondrial status, and cGAS-STING signaling were evaluated using behavioral tests, immunostaining, biochemical assays, and pharmacological inhibition. Sevoflurane exposure induced cognitive impairment, microglial overactivation, mitochondrial dysfunction, and excessive synaptic pruning resulting from microglial overactivation. EE mitigated these abnormalities by preserving mitochondrial integrity and reducing mtDNA-driven cGAS-STING activation, thereby preventing the microglia-mediated imbalance in synaptic pruning and improving cognitive outcomes. In contrast, IE exacerbated mitochondrial injury, aggravated synaptic loss, and further worsened cognitive impairment. Sevoflurane disrupts neurodevelopment through a mitochondria-cGAS-microglia-synapse pathway. Environmental enrichment offers significant neuroprotection, highlighting both cGAS-STING signaling and early-life environmental modulation as promising targets for preventing anesthesia-related neurodevelopmental injury."

The hallmarks of the disease are amyloid plaque accumulation, microglia and astrocyte activation, and loss of presynaptic structure leading to cognitive decline. Recently, oligodendrocyte (OL) and myelin abnormalities have emerged as important contributors to the pathogenesis of AD. In normal brain homeostatic conditions, OL maintain neuronal health through myelin axon interactions and by supplying neurotrophic and metabolic support. How strengthening OL function may support neuronal health in AD neurodegeneration remains to be fully characterized and represents a gap in knowledge and a missed therapeutic opportunity. This study sought to examine how myelin and OL may improve neuronal deficits associated with AD. We have generated a novel mouse model (AD/cKO) by crossing the AppNL-G-F mouse, an established AD model, which carries three human AD mutations in the mouse App gene, with the FusOLcKO whose OL depleted of Fus (Fused in Sarcoma) produce thicker myelin associated with greater cholesterol biosynthesis. We evaluated spatial memory function with standardized cognitive testing. We evaluated microglia density and state, astrocytic activation and toxic phenotype, myelin density, cholesterol content, amyloid plaque burden, presynaptic structures, and neuronal hypoxic and oxidative damage in the hippocampus and cortex. We characterized the transcriptome of AD/cKO hippocampal OL compared to AD by using single-cell transcriptomic studies. Spatial working memory was fully preserved in the aged AD/cKO mouse relative to the AD mouse. This outcome was associated with reduced neuronal oxidative damage, preserved presynaptic structures at the amyloid plaque niches, and a shift in microglia state at the niches in both hippocampus and cortex. In contrast, amyloid plaque burden and microglia density were decreased in the hippocampus but not in cortex, uncoupling the neuronal and microglia effects from the amyloid burden. Fus dependent myelin increase was present in both hippocampus and cortex. Single-cell transcriptomics of AD/cKO hippocampal OL revealed upregulation of energy metabolism and antioxidant genes, suggesting a role of OL enhanced energy metabolism in mediating protection of neurons and affecting microglia state in AD pathology. This work provides new insight into how oligodendrocytes may protect neurons in AD, communicate with other glial cellular players, and point to potential targets for disease intervention aimed at slowing AD progression."

In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair."

This study investigates the mechanisms underlying PDN and aims to identify potential molecular treatment targets. Male C57BL/6\u00a0J wild-type mice were employed to establish a PDN model, receiving intrathecal administration of shRNA targeting Galectin-3 (sh-Gal-3), shRNA targeting YTHDF1 (sh-YTHDF1), a YTHDF1 overexpression vector, or the m6A inhibitor 3-deazaadenosine (3-DAA), either individually or in combination. Macrophages underwent gene knockdown or overexpression and/or treatment with the glycolysis inhibitor 2-deoxy-d-glucose (2-DG) or 3-DAA. Diabetes was confirmed by monitoring blood glucose levels. Pain behavior was evaluated using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) assessments. Expression levels of Gal-3 and YTHDF1 were analyzed via Real-time PCR and Western blot, while myelin phagocytosis was evaluated through immunofluorescence and/or transmission electron microscopy. Glycolysis was assessed by measuring glucose uptake, lactate production, extracellular acidification rate (ECAR), and oxygen consumption rate (OCR). The RNA pull-down assay facilitated the detection of YTHDF1 binding to Gal-3 mRNA, and the half-life of Gal-3 mRNA was measured following transcription blockade using actinomycin D. Additionally, meRIP-qPCR assessed the m6A modification on Gal-3 mRNA. In vivo analyses revealed upregulation of Gal-3, which colocalized with IBA1. Silencing Gal-3 alleviated mechanical allodynia and diminished myelin phagocytosis. In vitro, Gal-3 silencing inhibited glycolysis, while Gal-3 overexpression enhanced myelin phagocytosis, an effect reversed by 2-DG treatment. Furthermore, high glucose stimulation elevated YTHDF1 expression, subsequently increasing Gal-3 levels; this induction was abrogated by YTHDF1 knockdown. Mechanistically, YTHDF1 enhanced Gal-3 mRNA stability through an m6A-dependent mechanism, promoting glycolysis and myelin phagocytosis. Consistently, YTHDF1 overexpression exacerbated PDN symptoms and myelin phagocytosis in vivo, which were mitigated by YTHDF1 knockdown or 3-DAA administration.

Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention."

UAMC-3203 increased the survival of CD13-positive pericytes within infarct areas and enhanced infarct reduction in the subacute phase. In vitro, the glutathione peroxidase 4 inhibitor RAS-selective lethal 3 (RSL3) induced dose-dependent cell death in pericytes but not in endothelial cells, which was suppressed by UAMC-3203 but not by inhibitors of apoptosis or necroptosis. RSL3 induced lipid peroxidation in pericytes, as evidenced by malondialdehyde accumulation. Extracellular ferrous iron (Fe2+), but not ferric iron (Fe3+) or transferrin, caused intracellular Fe2+ accumulation and cell death in pericytes, which was further enhanced by oxygen-glucose deprivation with reperfusion and suppressed by UAMC-3203. Myelin debris containing abundant Fe2+ induced ferroptosis in cultured pericytes. These findings indicate that pericytes are a major ferroptosis-vulnerable cell type during ischemia-reperfusion and may represent a therapeutic target in acute ischemic stroke."

In vitro studies demonstrated that Plasmodium-infected red blood cells (pRBCs)-stimulated primary microglia formed extensive F-actin-rich tunneling nanotubes, which mediated the bidirectional transfer for mitochondria and facilitated intercellular trafficking of lysosomal contents and malarial pigment. These TNT-mediated intercellular communication amplified microglial activation, as evidenced by: (i) lipid peroxidation, (ii) mitochondrial dysfunction, and (iii) autophagosome (LC3+) accumulation. This process further amplifies neuroinflammation through TNF\u03b1/IL-6 secretion and expansion of CD45high microglial populations. Pharmacological TNT inhibition restores microglial homeostasis in ECM model. In conclusion, TNTs mediate neuroinflammation in the ECM model by transferring mitochondria and malarial pigment between microglia. Although mitochondrial transfer may transiently support cellular homeostasis, progressive malarial pigment accumulation triggers lipid metabolism dysregulation and amplified neuroinflammation. Inhibiting TNTs formation attenuates microglial hyperactivation, highlighting targeted regulation of TNT-mediated intercellular communication as a potential therapeutic approach for CM-associated neuropathology."

To date, the precise molecular mechanisms remain incompletely understood. Herein, we showed that DON triggers neurotoxicity by reprogramming microglial glycolysis via activation of the NQO1/NF-\u03baB pathway. Raffinose (Raf), a natural trisaccharide, effectively attenuated DON-induced neuroinflammation in vivo and in vitro. Mechanistically, Raf upregulated NQO1 transcription by selectively binding to Nrf2 at Val-514 and Cys-368, thereby reinforcing the NQO1-I\u03baB\u03b1 interaction, possibly through NQO1-associated regulatory interfaces. This interaction inhibited NF-\u03baB hyperactivation, suppressed glycolysis, and restored oxidative phosphorylation, thereby attenuating DON-induced pro-inflammatory microglial activation. Furthermore, NQO1 knockdown or Nrf2 knockout weakened the inhibitory effect of Raf on the NF-\u03baB signaling pathway and inflammatory activation state of microglia. In conclusion, our findings revealed that Raf supplementation could efficiently alleviate DON exposure-induced neuroinflammation and neurobehavioral deficits by modulating NQO1/NF-\u03baB-associated metabolic remodeling. These findings suggested that Raf may represent a potential therapeutic strategy against DON-induced neuroinflammation."

Conversely, N-acetylaspartate was not different between groups and remained stable over time. Ocrelizumab treatment is associated with declining myo-inositol levels measured by MRS in both RMS and PPMS. Myo-inositol offers a unique biomarker to track resolution of gliosis and reactive microglia with treatment. Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

This inflammatory process unfolds years before clinical symptoms, creating an opportunity for early intervention. In vivo imaging technologies that could detect and quantify microglial reactivity are therefore essential for early diagnosis, patient stratification, and evaluating emerging immunomodulatory therapies that target this fundamental driver of PD progression. Yet no standardized, sensitive, and specific technology currently achieves this goal. Molecular magnetic resonance imaging (mMRI) is uniquely suitable to address this problem because it integrates inherent high spatial resolution and soft-tissue contrast of conventional MRI with molecularly targeted contrast agents, enabling simultaneous acquisition of anatomical detail and functional/biological information at submillimeter isotropic resolution. Here we present a novel mMRI probe designed to specifically target colony stimulating factor-1 receptor, expressed primarily on microglia in the brain. In silico data show that the targeting ligand binds the extracellular Ig domain of the receptor. In vitro cell uptake studies with both murine and human microglia cell lines show that the probe binds the receptor triggering active cell uptake and in vivo MRI enabled effective separation of the A53T mouse model of Parkinson's disease from control mice using radiomics-assisted MR image analysis. Ex-vivo immunohistochemical analysis showed signal from the probe largely in the cytosolic compartment of IBA-1 reactive cells, confirming that the observed in vivo MRI signal is due primarily to retention of the agent by microglia. This novel technology has the potential to interrogate the rgional presentation of microglial activation in PD. A microglia targeted MRI probe generates disease-specific contrast after injection, clearly distinguishing A53T Parkinsonian mice from controls."

This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS."

In this study, we investigated the effects of hUCB-MNCs treatment in a mouse model of VaD induced by bilateral common carotid artery stenosis (BCAS).

Histopathological analyses demonstrated that hUCB-MNCs treatment attenuated white matter injury, preserved myelin integrity, and mitigated neuronal and synaptic damage. Integrated transcriptomic and proteomic analyses of corpus callosum (CC) tissues revealed enrichment of immune-regulatory, phagocytosis-related, and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT)-associated pathways after hUCB-MNCs treatment.

There is strong mechanistic evidence linking the cGAS-STING pathway to microglial overactivation, neuroinflammation, and demyelination in MS and related models. While the literature explicitly links EBV to MS and cGAS-STING to microglial-mediated neuroinflammation and demyelination, the direct causal integration of EBV reactivation inducing microglial-mediated demyelination *specifically* through the cGAS-STING pathway in MS is strongly suggested as a potential disease-driving mechanism, though further longitudinal human data are needed to confirm the complete pathway.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific evidence suggests that Epstein-Barr virus (EBV) serves as an upstream trigger for Multiple Sclerosis (MS). Mechanistically, this process involves viral-induced reshaping of the neuroimmune environment, characterized by microglial activation and chronic neuroinflammation. The cGAS-STING axis has been identified as a critical intracellular signaling pathway driving this neuroinflammatory phenotype, leading to demyelination and neurodegeneration. \n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is an immune-mediated disorder where environmental factors, most notably EBV, play a fundamental role in disease initiation. The literature establishes that \"Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development.\" Furthermore, \"When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS.\" \n\nOnce reactivated, viruses or viral components may trigger innate immune responses. In the context of MS and other neurodegenerative diseases, \"Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.\" Activation of this pathway in microglia is a known driver of M1 polarization and neuroinflammation, as \"Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events.\" \n\nThe link to myelin damage is further solidified by the observation that \"Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens.\" Consequently, targeting this axis shows therapeutic promise, as \"From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV acts as an essential trigger for MS, and viral persistence in the CNS drives a long interval before disease manifestation.\n* The formation of Tertiary Lymphoid Structures (TLS) in the CNS during MS relapse correlates with persistent microglial activation.\n* Cross-reactivity via molecular mimicry between EBV antigens (e.g., EBNA1, LMP1) and CNS proteins (e.g., MBP, MOG) is a central etiopathogenic mechanism.\n* cGAS-STING signaling serves as a \"rheostat\" for neuroinflammation, where loss of control leads to persistent microglial M1 polarization.\n* Microglial mitochondrial dysfunction and mtDNA release are significant \"danger signals\" that activate the cGAS-STING pathway.\n* Therapeutic inhibition of the STING pathway has demonstrated efficacy in reducing neuroinflammation across multiple EAE and CNS injury models.\n* The potential use of viral platforms as engineered vectors for neuro-repair represents a paradoxical application of viruses in neurology.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The provided literature corroborates that EBV is linked to MS, that microglial activation is a driver of demyelination, and that the cGAS-STING pathway mediates inflammatory responses. However, while these components are individually supported, a direct, singular, closed-loop causal mechanism linking all three stages\u2014EBV reactivation, STING-mediated microglial activation, and myelin destruction\u2014in a single patient-level longitudinal sequence remains an area of active investigation requiring further clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple sclerosis (MS) is a chronic autoimmune demyelinating disorder of the central nervous system (CNS), characterized by microglial activation and polarization as key drivers of disease pathogenesis. Growing evidence indicates that Epstein-Barr virus (EBV), a gammaherpesvirus, plays a central role in the pathogenesis of multiple sclerosis (MS). These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. \n\nPathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway. However, the exact timing and necessity of these pathways in the specific context of EBV-triggered microglial activation demand more rigorous scrutiny, as individual research components link viral persistence to primed microglial phenotypes marked by elevated MHC-II expression and heightened immune reactivity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV persistence is observed in the CNS of MS patients, but not in neurologically healthy individuals, suggesting a unique pathogenic niche.\n* Prior infection with a gammaherpesvirus sensitizes the host to a second, unrelated inflammatory stimulus, accelerating CNS demyelination.\n* The cGAS-STING pathway is both a pro-inflammatory driver in disease and a potentially protective node depending on its activation state, with down-regulation observed in some RRMS patients.\n* Neurons themselves can induce STING in response to inflammatory stress triggered by glutamate excitotoxicity, independent of microglial signaling.\n* Microglial activation in the spinal cord is often dysfunctional, characterized by ameboid morphology and delayed phagocytosis compared to the brain.\n* Ataxin-1, a gene linked to MS risk via genome-wide association studies, modulates B-cell biology and is enriched in memory and precursor B-cell subsets.\n* Viral reactivations post-transplant follow early kinetics, with BK virus associated with hemorrhagic cystitis and EBV showing transient fluctuations.\n* Berberine and similar alkaloids offer neuroprotective effects, potentially by modulating the JAK/STAT signaling pathway to reduce inflammatory demyelination.\n* Mitochondrial DNA leakage serves as an inflammatory trigger, activating cGAS-STING-mediated pyroptosis in astrocytes in epilepsy models.\n* Clinical disability progression in MS may occur independently of acute inflammatory attacks, pointing toward smouldering inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While mitochondrial DNA leakage and cGAS-STING activation are verified drivers of neuroinflammation and white matter pathology in various neurological conditions, the evidence linking these to EBV specifically is limited to the potential role of extracellular vesicles (sEVs) in disseminating viral components such as EBER1.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenesis of Multiple Sclerosis is increasingly recognized as a multi-axial process involving both peripheral immune triggers and chronic, compartmentalized neuroinflammation. Epigenetic and metabolic studies indicate that \"Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression.\" Specifically, the cGAS-STING axis has emerged as a major mediator of such progression, as \"mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction.\" \n\nWhile EBV is a strong candidate as an MS trigger, its precise mechanism of CNS influence remains under scrutiny. Current literature identifies sEVs as a vector for viral components, noting that \"EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency\". However, the direct, causal coupling of EBV-encoded products to cGAS-STING activation in microglia, and the subsequent extent of myelin loss, requires further investigation. We observe that \"Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner,\" suggesting that viral-induced metabolic reprogramming could potentially act as a trigger.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **sEV-Mediated Viral Dissemination:** Small extracellular vesicles act as carriers for immunostimulatory EBV non-coding RNAs (EBER1) to distal tissues.\n* **cGAS-STING Rheostat:** The cGAS-STING pathway functions as a tunable control node, not merely a binary switch, making it highly sensitive to metabolic shifts.\n* **Mitochondrial DNA (mtDNA) Leakage:** Cytosolic leakage of mtDNA is a conserved activator of STING-mediated neuroinflammation across AD, PD, and ischemia models.\n* **Metabolic Checkpoints:** Lactylation of core pathway components serves as a metabolic-immune bridge regulating STING stability and activity.\n* **Regional Glial Heterogeneity:** Spinal cord and brain microglia exhibit distinct activation profiles during demyelination, complicating global neuroinflammatory models.\n* **T-Cell-Microglia Crosstalk:** Cytotoxic NK-like CD8+ T cells spatially associate with microglia in MS lesions, linking peripheral immune states to local tissue destruction.\n* **Mitochondrial Protection:** Preserving mitochondrial integrity effectively suppresses mtDNA-driven innate immune activation, as demonstrated by the efficacy of EE and other interventions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

development.\nMechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.\nMyelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens.\nWhen the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS.\nCollectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role.\nMechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism.\nHSY attenuated adverse cardiac remodeling following MI by inhibiting STING-mediated ZBP1-PANoptosome assembly and subsequent PANoptosis.\nOxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events.\nThe growing significance of three-dimensional (3D) brain organoids (BOs) derived from induced pluripotent stem cells (iPSCs) can be used as a groundbreaking platform for examining neurodegenerative pathways induced by exposure to environmental toxicants and viral infections.\nHere, robust activation of the cGAS-STING-IFN-I signaling pathway is identified in myeloid cells in both the periphery and central nervous system.\nFrom a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.\nHere, using the relapsing-remitting PLP139-151-induced EAE model, we

vaccine.\nAdenovirus-infected macrophages elicited a robust type I IFN response via the cGAS/STING pathway.\nWhile initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context.\nThrough these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling.\nAcross these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response.\nNucleotide-binding oligomerization domain-like receptors detect pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), activating multiple signaling pathways, including nuclear factor-\u03baB (NF-\u03baB) and mitogen-activated protein kinase (MAPK), and triggering immune responses through inflammasome activation.\nRadiotherapy can induce DNA damage and immunogenic cell death, promote tumor antigen release, enhance dendritic cell maturation and antigen cross-presentation, and increase CD8+ T-cell infiltration and antitumor immunity through the cGAS-STING type I interferon pathway.\nGrowing evidence indicates that Epstein-Barr virus (EBV), a gammaherpesvirus, plays a central role in the pathogenesis of multiple sclerosis (MS).\nMultiple sclerosis (MS) is a chronic autoimmune demyelinating disorder of the central nervous system (CNS), characterized by microglial activation and polarization as key drivers of disease pathogenesis.\nMechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway\nIn contrast, specific STING activation and subsequent IFN-\u03b2 release have shown beneficial effects on experimental autoimmune encephalomyelitis (EAE) as a model for multiple sclerosis (MS).\nOur study is the first to provide evidence that the STING/IFN-\u03b2-axis is downregulated in RRMS patients\nFurther investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months.\nPathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host.\nBy dissecting the neuronal inflammatory stress response, we discovered that neurons in MS and its mouse model induce the stimulator of interferon genes (STING).\nNET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response.\nThese findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations.\nConcerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant.\nThe combined use of rituximab during the conditioning regimen may be regarded as an effective strategy for preventing EBV reactivation after rATG - based haplo - HSCT\nCurrent data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden.\nRecent evidence from genome-wide association studies has linked the ataxin-1 gene (ATXN1) to an increased risk of developing the autoimmune demyelinating disorder multiple sclerosis.\nTranscriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway.\nBy analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation.\nBerberine (BBR), a naturally occurring isoquinoline alkaloid, has emerged as a promising therapeutic candidate due to its potent immunomodulatory, anti-inflammatory, and neuroprotective properties.\nMechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation.\nPharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage.\nMultiple sclerosis (MS) is a chronic autoimmune demyelinating disorder of the central nervous system (CNS), characterized by microglial activation and polarization as key drivers of disease

Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development. This is supported by pathology findings revealing EBV-infected B cells within CNS lesions and immunogenetic data linking viral and human genetic susceptibility to MS risk. Mechanistically, EBV appears to act as an upstream trigger that reshapes B cell function, promotes molecular mimicry with CNS antigens, and drives compartmentalized neuroinflammation. In this Review, we synthesize epidemiological, pathological, immunogenetic, and clinical-therapeutic evidence to construct a coherent model of EBV-driven MS pathogenesis. We examine how current MS therapies intersect with EBV biology and discuss the challenges and opportunities in developing EBV-targeted strategies, including vaccines and antivirals, for disease prevention and early intervention. Finally, we highlight key unresolved questions and outline a translational research agenda aimed at intercepting MS through virologically informed approaches."

Typically occurring in young and middle-aged individuals, untreated MS can have high rates of disability and recurrence, thereby imposing a significant burden on the patient, their family, and society. Many factors are implicated in the etiology of MS, with the relationship between Epstein-Barr Virus (EBV) infection and the development of MS being the subject of extensive research recently. When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS. Currently, the phenomenon of cross-reactivity resulting from molecular mimicry following EBV infection (including reactivation status) is theorized as a contributing etiology. EBV-mediated abnormalities in T cells and B cells also play a key role in the development of MS. However, the underlying mechanisms have not been thoroughly understood. Meanwhile, the limited availability of effective treatment options for MS, in particular MS progression, underscores the urgent need for novel therapeutic strategies. Here, we discuss the pathophysiological mechanisms underlying MS, specifically emphasizing the relationship between EBV infection and the disease pathology. Furthermore, we introduced relevant pharmacological targets in order to propose a broader range of therapeutic alternatives for individuals diagnosed with MS."

These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self-epitopes in the central nervous system (CNS). This study seeks to explore the common pentapeptides present in EBV and HHV-6 viral antigens alongside various CNS-related proteins via molecular mimicry. Additionally, it will assess the immunogenicity of these shared pentapeptides in T and B cells. Sequence alignment was conducted to assess molecular mimicry between 32 EBV and HHV-6 antigens and 10 CNS autoantigens. Protein sequences were obtained from UniProt, structural homology was analyzed using AlphaFold and PyMol, and shared pentapeptides were identified with Alignmentaj. Immunogenicity was assessed via the Immune Epitope Database (IEDB) for potential T- and B-cell activation. A total of 91 mimicry pentapeptides were identified between viral antigens (42 EBV and 49 human HHV-6), and 10 CNS proteins. Notably, synapsin (SYN)1 exhibited the highest mimicry, sharing 13 pentapeptides with (7 with EBV and 6 with HHV-6) viral antigens such as EBV nuclear antigen (EBNA)1, EBNA6, latent membrane protein (LMP)1, and early antigen diffused (EA-D). Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens. EBNA1, EBNA2, EBNA6, LMP1, LMP2, EA-D, and BLLF1 structurally resemble CNS autoantigens and act as immunoreactive epitopes for human T and B cells. Except for EBNA2 and protein U94, all share immunogenic pentapeptide sequences with SYN1. Shared pentapeptides suggest a link between viral infections and CNS autoimmunity. Further research is needed to clarify molecular mechanisms and explore targeted therapies to mitigate virus-induced neuroinflammation."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.

Recent studies have demonstrated that oxymatrine inhibits experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), by promoting the production of interferon-\u03b2 (IFN-\u03b2). However, the mechanism through which oxymatrine regulates the production of IFN-\u03b2 remains unclear. The aim of this study was to investigate the pharmacological effects and related molecular mechanisms of oxymatrine in the treatment of EAE through in vivo and in vitro experiments. Oxymatrine alleviated neurological dysfunction, demyelination, and inflammation in EAE mice. It reduced microglia/macrophage infiltration and polarization, lowered pro-inflammatory cytokine levels (iNOS, TNF-\u03b1), and enhanced the expression of IL-10 and IL-27. Additionally, oxymatrine upregulated the STING/TBK1/IRF3 signaling pathway in EAE mice, promoting IFN-\u03b2 production by microglia. Similarly, in LPS-induced BV2 cells, oxymatrine suppressed inflammatory factors and activated the STING/TBK1/IRF3 pathway to enhance IFN-\u03b2 production. Notably, treatment with the STING inhibitor, C176, reversed these effects in both EAE mice and LPS-induced BV2 cells, confirming the pathway's critical role in the mechanism of oxymatrine therapy. Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events. This study identifies a novel anti-EAE mechanism of oxymatrine: promoting IFN-\u03b2 production in microglia by activating the STING/TBK1/IRF3 pathway. However, it lacks clinical sample verification. If validated later, oxymatrine may provide a more economical, convenient endogenous IFN-\u03b2 induction regimen for MS patients."

Prior attempts to treat NMOSD with interferon-beta (IFN-\u03b2), a disease-modifying therapy for multiple sclerosis, resulted in worsening of disease activity, with an unknown mechanism. Here, robust activation of the cGAS-STING-IFN-I signaling pathway is identified\u00a0in myeloid cells in both the periphery and central nervous system. The abnormal IFN-I response gives rise to an increase in the number of AQP4 antigen-specific autoreactive T cells. Sting deficiency can significantly blunt the activation of AQP4-specific T cells, as well as the IFN-I activity in microglia, and attenuate astrocyte damage. Consequently, the clinical manifestation of NMOSD is ameliorated in a passive transfer mouse model of NMOSD. Further, treatment with STING inhibitor H151 alleviates the severity of NMOSD mouse models. These findings uncover the cGAS-STING-IFN-I pathway in promoting autoreactive T cells and establish a foundation for inhibiting this pathway as a new therapeutic revenue for NMOSD."

Tertiary lymphoid structures (TLS) are extensively documented in progressive MS at autopsy, but whether their formation begins during the relapsing-remitting phase and how they evolve during the transition to progression remain undefined. Here, using the relapsing-remitting PLP139-151-induced EAE model, we uncover that TLS-like structures form in the subventricular zone during relapse, once established, persist through remission as niches containing both B cells and persistently activated microglia. Neither B-cell depletion alone nor BTK inhibition alone fully prevents relapse. Strikingly, early combined B-cell depletion and BTK inhibition virtually abolishes TLS-like structure formation and may effectively prevent complete disease relapse in this model. By contrast, late initiation of the same combination fails to resolve existing TLS-like structures or prevent relapse, although it attenuates disease severity. These data indicate that established TLS-like structures may represent treatment-resistant compartments, and that both B cells and microglia may be crucial during early formation for sustaining their disease relapse-driving activity. Our study confirms that TLS-like structures may be a key factor driving the compartmentalization of central nervous system inflammation, points to a potentially narrow therapeutic window for intervention, and proposes that early combined B-cell depletion and BTK inhibition may represent a promising strategy worthy of further investigation."

This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders."

Hongqi Shenmai Yin (HSY) has been used in clinical practice for many years, can improve cardiac function in MI patients. However, its underlying therapeutic mechanisms remain unclear. This study aimed to determine whether HSY alleviates adverse cardiac remodeling following MI by inhibiting stimulator of interferon genes (STING)-dependent PANoptosis. The MI model was established by ligating the left anterior descending coronary artery (LAD) in rats. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS) identified bioactive compounds in HSY. Cardiac function, hypertrophy, and fibrosis were assessed via echocardiography and histological staining. ELISA measured cardiac injury biomarkers, inflammatory cytokines, and oxidative stress markers. Transcriptomic analyses identified potential HSY targets in post-MI remodeling. Molecular docking and surface plasmon resonance (SPR) assessed binding interactions between HSY's key active components and STING. Mechanistic rescue experiments determined whether HSY regulates PANoptosis via STING inhibition. Functional studies were further conducted by transfecting H9c2 cardiomyocytes with lentivirus vectors encoding STING-overexpression. HSY attenuated inflammation, oxidative stress, and adverse remodeling while improving cardiac function post-MI. UPLC-MS identified 107 major HSY constituents. Transcriptomics linked HSY's cardioprotective effects to STING signaling and PANoptosis modulation. Molecular docking and SPR confirmed strong binding affinity between HSY's primary active compounds and STING. Both in vivo and in vitro experiments revealed that HSY suppressed STING-induced ZBP1-PANoptosome assembly, downregulating PANoptosis-associated proteins (p-MLKL, p-RIPK1, p-RIPK3, GSDMD-NT, GSDME-NT, Cle-CASP1, Cle-CASP3, Cle-CASP8) in post-MI remodeling.

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

This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration."

Peptide vaccines targeting T cell epitopes of high-risk human papillomavirus (HPV) E6 and E7 represent a promising immunization strategy. To improve immunogenicity, we utilized the STING agonist 2'3'-cGAMP as an adjuvant and evaluated its ability to enhance immune responses and antitumor efficacy. The immunogenicity and efficacy of a candidate vaccine, consisting of the HPV16 E743-77 peptide adjuvanted with 2'3'-cGAMP, were evaluated in established TC-1 tumor transplantation models with different initial tumor sizes (2-3 mm and 5-6 mm in diameter). Tumor-bearing mice received three weekly peritumoral subcutaneous vaccine doses. The effects on tumor suppression, antigen-specific cytotoxic T lymphocyte (CTL) response induction, and related immune mechanisms were investigated both in vitro and in vivo. Immunization with the E743-77 peptide adjuvanted by 2'3'-cGAMP significantly suppressed tumor growth and elicited high levels of Interferon (IFN)-\u03b3 and Granzyme B in CD8+ cytotoxic T lymphocytes.

Previous studies in mice have shown that stimulating type I interferon (IFN) signaling during BCG vaccination can bolster protection against Mycobacterium tuberculosis , yet clinically feasible delivery strategies for this approach are lacking. Adenoviral vectors, which induce potent type I IFN responses and are utilized in approved vaccine platforms, represent a promising adjuvant strategy. To evaluate the host immune response to this combination, bone marrow-derived murine macrophages were co-infected with replication-deficient adenovirus and BCG. Adenovirus-infected macrophages elicited a robust type I IFN response via the cGAS/STING pathway. Compared to BCG infection alone, co-infected macrophages exhibited additive expression of genes with known host-protective roles against M. tuberculosis . Conversely, co-infection with BCG suppressed adenovirus-induced type I IFN signaling and diminished the production of IFN-stimulated genes compared to adenovirus infection alone. Together, these findings reveal a complex regulatory interplay during adenovirus and BCG co-infection. While BCG partially restricts adenoviral IFN induction, the co-infection still drives an enhanced host-protective gene profile, suggesting that adenoviral vectors could serve as a viable platform to modulate innate immunity and improve BCG vaccine efficacy. Tuberculosis (TB) remains the leading cause of death by a single infectious organism with approximately 1.25 million deaths annually. M. bovis BCG remains the only approved vaccine for TB; however, its efficacy against the contagious and most common pulmonary form of the disease is limited. There have been numerous attempts to improve BCG efficacy, but these approaches have not resulted in any clinically approved vaccine. We propose that BCG combined with a replication-deficient adenovirus presents a way to bolster vaccine-conferred protection as the combination may elicit a robust innate immune response and drive a more protective T cell response. Moreover, BCG and replication-deficient adenoviruses have well-assessed safety profiles and decades of studies regarding their use in patients. The significance of our work is in leveraging their complementary immunology to function as a combined vaccine platform. This approach presents a novel and clinically feasible approach to improve the BCG vaccine."

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

Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks. In this review, we summarize current insights into the molecular and cellular roles of ISG15 in neuroinflammation, highlight its dual protective and pathogenic functions, and discuss therapeutic strategies and future directions for targeting ISG15-related pathways in CNS diseases."

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

Its role has expanded from conventional local tumor eradication to active regulation of the tumor immune microenvironment. In recent years, emerging radiotherapy strategies, including FLASH radiotherapy, boron neutron capture therapy, lattice radiotherapy, spatially fractionated radiation therapy, precision particle therapy, immunomodulatory stereotactic body radiotherapy, and immune-optimized carbon ion therapy, have provided new opportunities to improve tumor control, reduce normal tissue toxicity, and overcome radioresistance. Radiotherapy can induce DNA damage and immunogenic cell death, promote tumor antigen release, enhance dendritic cell maturation and antigen cross-presentation, and increase CD8+ T-cell infiltration and antitumor immunity through the cGAS-STING type I interferon pathway. However, radiotherapy may also trigger immunosuppressive feedback, including the accumulation of myeloid-derived suppressor cells, tumor-associated macrophages, and regulatory T cells, as well as the upregulation of immune checkpoint molecules such as programmed death-ligand 1 (PD-L1). These changes may limit antitumor immune responses and contribute to radioresistance. Combining radiotherapy with immune checkpoint inhibitors can amplify antitumor immunity, but therapeutic efficacy is influenced by dose fractionation, treatment timing, tumor type, and baseline immune status. This mini review summarizes emerging radiotherapy strategies and their regulatory effects on the tumor immune microenvironment, and discusses the mechanistic basis, current challenges, and future directions of radiotherapy combined with immunotherapy."

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Does chronic latent Epstein-Barr Virus (EBV) reactivation drive microglial activation and subsequent myelin destruction in Multiple Sclerosis via the activation of the cGAS-STING innate immune pathway?\"\n\nThe provided literature supports that EBV infection is a necessary precondition for Multiple Sclerosis (MS) and that reactivation triggers inflammatory processes. There is strong mechanistic evidence linking the cGAS-STING pathway to microglial overactivation, neuroinflammation, and demyelination in MS and related models. While the literature explicitly links EBV to MS and cGAS-STING to microglial-mediated neuroinflammation and demyelination, the direct causal integration of EBV reactivation inducing microglial-mediated demyelination *specifically* through the cGAS-STING pathway in MS is strongly suggested as a potential disease-driving mechanism, though further longitudinal human data are needed to confirm the complete pathway.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific evidence suggests that Epstein-Barr virus (EBV) serves as an upstream trigger for Multiple Sclerosis (MS). Mechanistically, this process involves viral-induced reshaping of the neuroimmune environment, characterized by microglial activation and chronic neuroinflammation. The cGAS-STING axis has been identified as a critical intracellular signaling pathway driving this neuroinflammatory phenotype, leading to demyelination and neurodegeneration. \n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is an immune-mediated disorder where environmental factors, most notably EBV, play a fundamental role in disease initiation. The literature establishes that \"Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development.\" Furthermore, \"When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS.\" \n\nOnce reactivated, viruses or viral components may trigger innate immune responses. In the context of MS and other neurodegenerative diseases, \"Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.\" Activation of this pathway in microglia is a known driver of M1 polarization and neuroinflammation, as \"Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events.\" \n\nThe link to myelin damage is further solidified by the observation that \"Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens.\" Consequently, targeting this axis shows therapeutic promise, as \"From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV acts as an essential trigger for MS, and viral persistence in the CNS drives a long interval before disease manifestation.\n* The formation of Tertiary Lymphoid Structures (TLS) in the CNS during MS relapse correlates with persistent microglial activation.\n* Cross-reactivity via molecular mimicry between EBV antigens (e.g., EBNA1, LMP1) and CNS proteins (e.g., MBP, MOG) is a central etiopathogenic mechanism.\n* cGAS-STING signaling serves as a \"rheostat\" for neuroinflammation, where loss of control leads to persistent microglial M1 polarization.\n* Microglial mitochondrial dysfunction and mtDNA release are significant \"danger signals\" that activate the cGAS-STING pathway.\n* Therapeutic inhibition of the STING pathway has demonstrated efficacy in reducing neuroinflammation across multiple EAE and CNS injury models.\n* The potential use of viral platforms as engineered vectors for neuro-repair represents a paradoxical application of viruses in neurology.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.\n\nID: 42166973\nTitle: Epimedium brevicornu flavonoids alleviate neuroinflammation and Alzheimer's disease pathology via immune-related pathways.\nAbstract: With global population aging, Alzheimer's disease (AD) has become a critical clinical challenge. This multifactorial neurodegenerative disorder is characterized by amyloid-\u03b2 aggregation, tau hyperphosphorylation, and neuroinflammation. The lack of effective disease-modifying therapies highlights the urgent need for multi-target strategies. Epimedium brevicornu flavonoids (EF), derived from a traditional medicinal plant used to support cognitive function, exhibit significant neuroprotective potential; however, the underlying mechanisms remain to be fully elucidated. To investigate the neuroprotective effects and underlying mechanisms of EF against lipopolysaccharide (LPS)-induced neuroinflammation and Alzheimer's disease-related pathology. EF were extracted and quantitatively analyzed. Mice were pretreated with EF for 14 days before LPS injection (1.0 mg/kg). Behavioral performance was assessed using the Open field, Y-maze, and Morris water maze tests. EF components in extract, serum, and brain were characterized by UHPLC-QTOF-MS/MS. Network pharmacology and molecular docking were employed to predict active compounds, targets, and signaling pathways. ELISA, Western blot, and immunofluorescence were conducted to evaluate cytokine levels, microglial and astrocytic activation, A\u03b242 deposition, tau phosphorylation, and NeuN+ neuronal density. The involvement of PI3K/AKT and cGAS-STING pathways was further validated. In BV2 microglia, NO release and iNOS/Iba1 as well as CD206/Iba1 expression were examined to verify anti-inflammatory effects of EF in vitro. A total of 127 components in EF were identified, among which 45 and 38 were detected in serum and brain, respectively. The key compounds showed favorable target binding (<-6.2 kcal/mol). EF markedly improved cognition performance in LPS-treated mice, suppressed systemic inflammation and neuroinflammation, inhibited glial activation, reduced APP/BACE1/A\u03b242 expression and tau phosphorylation, and preserved neuronal integrity. Mechanistically, EF inhibited PI3K/AKT and cGAS-STING signaling pathways in vivo and promoted M2 polarization in BV2 microglia in vitro. EF confers neuroprotection against LPS-induced cognitive impairment, a process linked to the modulation of neuroinflammation, A\u03b2 generation, and tau phosphorylation, and associated with PI3K/AKT and cGAS-STING signaling pathways. These findings highlight EF as a promising multi-target candidate for mitigating inflammation-driven AD-relevant pathological features.\n\nID: 42090738\nTitle: STING-dependent microglial inhibition by irisin ameliorates neuroinflammation in experimental autoimmune encephalomyelitis.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune demyelinating disorder of the central nervous system (CNS), characterized by microglial activation and polarization as key drivers of disease pathogenesis. Irisin, an exercise-induced myokine, has been reported to exhibit neuroprotective effects, including anti-inflammatory activity and cognitive improvement. To investigate the therapeutic potential of irisin in the experimental autoimmune encephalomyelitis (EAE) mouse model and its effects on microglial behavior along with the underlying molecular mechanisms, we conducted the present study. Results demonstrated that irisin treatment significantly alleviated EAE severity, evidenced by reduced disease incidence, attenuated weight loss, and improved neurological scores. Histopathological analysis revealed that irisin suppressed inflammatory cell infiltration and reduced demyelination in spinal cord tissues. Furthermore, irisin inhibited microglial overactivation and promoted a phenotypic shift from the pro-inflammatory M1 to the anti-inflammatory M2 microglia. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, as indicated by downregulation of STING and phosphorylated interferon regulatory factor 3 (p-IRF3) expression. Collectively, these findings indicate that irisin alleviates neuroinflammation and exerts neuroprotective effects in EAE by modulating microglial activity through inhibition of the cGAS-STING pathway, underscoring its potential as a novel therapeutic candidate for MS.\n\nID: 42039182\nTitle: A perfect storm: the immunological and pathophysiological landscape of pediatric post-COVID-19 condition.\nAbstract: Pediatric Post-COVID Condition (PPCC) represents a significant and complex long-term sequela of SARS-CoV-2 infection, affecting a subset of children and adolescents even after mild acute disease. While acute COVID-19 is generally milder in children due to a more robust innate immune response, the mechanisms driving the persistence of symptoms in PPCC remain incompletely understood and likely multifactorial. This narrative review synthesizes current epidemiological data and explores the \"perfect storm\" of immunological and pathophysiological alterations underpinning the condition. We examine critical hypotheses including a dysregulated immune response characterized by altered T-cell subsets, monocyte activation, and autoantibody production. We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in \"sanctuary sites\" like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV). Furthermore, the review details downstream pathogenic pathways, including vascular endothelial inflammation (thrombo-inflammation), neuroinflammation, and metabolic dysfunctions affecting the mitochondria and tryptophan-kynurenine pathway. Finally, we address the role of microbiome dysbiosis in perpetuating systemic inflammation and the gut-lung axis dysfunction. Given the heterogeneity of clinical presentations, we conclude that PPCC is likely a syndrome of overlapping biological phenotypes. Future research must prioritize identifying these specific biological endotypes to develop targeted diagnostic and therapeutic strategies for the pediatric population.\n\nID: 41702466\nTitle: Zhi-Zi-Hou-Po decoction ameliorates depressive-like behaviors via TFAM-induced mitophagy in neurons to alleviate neuroinflammation.\nAbstract: Zhi-Zi-Hou-Po decoction, a classic herbal formula in traditional Chinese medicine, has long been used clinically for the treatment of depression. However, the precise molecular mechanisms underlying its antidepressant effects remain to be fully elucidated. This study aimed to characterize the chemical composition of ZZHP and investigate its antidepressant-like effects and underlying mechanisms, specifically focusing on the regulation of Mitochondrial Transcription Factor A (TFAM)-mediated mitophagy and the cGAS-STING innate immune pathway. Chemical constituents of ZZHP were profiled using UPLC-Q-TOF-MS/MS. The antidepressant efficacy was evaluated in vivo using a Chronic Unpredictable Mild Stress (CUMS) mouse model with behavioral batteries (SPT, TST, FST, OFT) and in vitro using corticosterone (CORT)-injured PC12\u00a0cells. Mechanistic explorations involved immunofluorescence, Western blotting, transmission electron microscopy, and co-immunoprecipitation to assess mitochondrial integrity, autophagy flux, and the TFAM-LC3B interaction. Furthermore, TFAM-targeted siRNA transfection and a neuron-microglia co-culture system were employed to verify the molecular targets and intercellular crosstalk. Chromatographic analysis identified 22 bioactive compounds within ZZHP. In CUMS mice, ZZHP administration robustly ameliorated depressive-like behaviors, restored hippocampal neuronal morphology, and attenuated oxidative stress and neuroinflammation. Mechanistically, ZZHP upregulated neuronal TFAM expression and enhanced the formation of the TFAM-LC3B complex, thereby facilitating the autophagic clearance of damaged mitochondria and cytosolic mtDNA. This restoration of selective mitophagy effectively abrogated the activation of the cGAS-STING signaling pathway. Notably, TFAM knockdown in PC12\u00a0cells abolished the neuroprotective and anti-inflammatory effects of ZZHP, confirming TFAM as a critical therapeutic target. Additionally, ZZHP-conditioned neuronal medium promoted the polarization of microglia toward the anti-inflammatory M2 phenotype. These findings indicate that ZZHP exerts potent antidepressant effects by orchestrating TFAM-dependent mitophagy to eliminate immunogenic mtDNA, thereby inhibiting the cGAS-STING inflammatory axis and remodeling the neuroimmune microenvironment.\n\nID: 41702081\nTitle: Neuronal TLR4 upregulation activates the cGAS-STING pathway to induce ferroptosis in EAE mice.\nAbstract: Progressive neurofunctional impairment in multiple sclerosis (MS) is largely driven by neuronal damage and loss, yet the underlying molecular mechanisms remain poorly understood. This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration.\n\nID: 41638453\nTitle: Buyang Huanwu Decoction alleviates vascular cognitive impairment by inhibiting neuroinflammation via regulation of the p53/cGAS/STING pathway.\nAbstract: Buyang Huanwu Decoction (BYHWD), a traditional Chinese medicine (TCM) formulation renowned for its properties in replenishing qi and promoting blood circulation, corresponds closely with the pathophysiological framework of \"qi deficiency and blood stasis\" observed in vascular cognitive impairment (VCI). Consequently, there is a critical need to validate its therapeutic efficacy and elucidate the pharmacological mechanisms underlying its use in VCI treatment. This investigation aimed to systematically assess the therapeutic effects of BYHWD on VCI and to clarify the molecular mechanisms involved. The bioactive constituents of BYHWD were characterized via UHPLC-MS/MS. A rat model of VCI was established through two-vessel occlusion (2VO). Experimental groups received oral gavage administration of BYHWD at dosages of 6.4, 12.8, and 25.6\u00a0g/kg daily for four weeks, with Ginaton (14.4\u00a0mg/kg) employed as a positive control. Cerebral blood flow was assessed using laser speckle imaging. Cognitive performance was evaluated through the Morris water maze (MWM) test. Histopathological changes in brain tissue were assessed by Nissl and LFB staining. To investigate pharmacological mechanisms, ELISA, immunohistochemistry, Western blot, and immunofluorescence analyses were conducted. Additionally, in vitro studies utilized an oxygen-glucose deprivation (OGD) model in BV2 microglial cells, with intervention by the p53 activator Nutlin-3 to further validate mechanistic pathways. Administration of BYHWD markedly enhanced learning and memory functions, increased cerebral perfusion, and mitigated neuronal loss and white matter injury in 2VO rats. Furthermore, BYHWD significantly inhibited microglial activation and decreased the secretion of pro-inflammatory cytokines. Mechanistic investigations demonstrated that BYHWD downregulated the expression of proteins associated with the p53/cGAS/STING signaling pathway in the 2VO model. In vitro, activation of p53 by Nutlin-3 negated the neuroprotective effects of BYHWD on OGD-induced BV2 cells and concurrently intensified inflammatory responses. BYHWD ameliorates cognitive deficits and neuropathological damage in 2VO rats primarily through suppression of the p53/cGAS/STING signaling cascade and attenuation of neuroinflammation. This study provides strong pharmacological evidence for the early prevention and clinical treatment of VCI.\n\nID: 41484491\nTitle: Microglia Mitochondrial Metabolism in Neurological Diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), play critical roles in maintaining brain homeostasis and responding to neurological insults. Recent advances have fundamentally reshaped our understanding of how microglial mitochondrial metabolism influences neuroinflammation and disease progression. Single-cell transcriptomics has revealed unexpected metabolic heterogeneity, identifying distinct phenotypes such as disease-associated microglia (DAM) and lipid-laden microglia (LLM) that represent not merely activated states but terminal endpoints of metabolic paralysis. These discoveries converge on a unified pathogenic mechanism: mitochondrial quality control failure leads to mitochondrial DNA release, which activates the cGAS-STING pathway to create an \"epigenetic lock\" that drives sustained neuroinflammation. Interestingly, we highlight that the loss of metabolic flexibility-rather than glycolysis per se-is the true driver of pathology, explaining why the same metabolic shift can be protective during acute injury but pathological when sustained chronically. We critically examine conflicting evidence across Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ischemic stroke, including the puzzling dual roles of glycolysis, controversies surrounding the experimental autoimmune encephalomyelitis (EAE) model in multiple sclerosis research, and the paradoxical worsening of stroke outcomes following microglial depletion. By synthesizing these mechanistic insights with lessons from failed clinical trials, we identify critical translational gaps-including the lack of longitudinal human data and validated biomarkers-and propose a precision medicine framework focused on restoring mitochondrial dynamics and metabolic flexibility in neurological diseases.\n\nID: 41459768\nTitle: ETS Translocation Variant 5 Negatively Modulates Innate Immunity to Facilitate Epstein-Barr Virus Reactivation.\nAbstract: Epstein-Barr virus (EBV) is a member of the gamma-herpesvirus subfamily that is prevalent in the human population. There are two phases of EBV infection: latent infection and lytic infection. During lytic reactivation, host innate immune responses are activated to restrict EBV replication. Here, we identified ETS translocation variant 5 (ETV5) as a negative regulator of innate immune responses to facilitate EBV reactivation. ETV5 expression was upregulated by the EBNA1/BRD7 axis, which had been previously described by us, during EBV latent infection. When EBV was induced into lytic replication, the expression of ETV5 was further increased, and ETV5 overexpression dramatically enhanced the lytic replication of EBV. Mechanistically, upon EBV reactivation, the overexpression of ETV5 suppressed the activation of TANK-binding kinase 1 and interferon regulatory factor 3 (IRF3), as well as the transcription of interferon beta (IFNB1) gene and interferon-stimulated genes (ISGs). The effect of ETV5 knockdown could be reversed by an inhibitor of innate immunity pathway. These findings position ETV5 as a critical accelerator of EBV reactivation through immune evasion, revealing new therapeutic targets for managing EBV-associated diseases.\n\nID: 41386298\nTitle: Sterile innate immune mechanisms in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by the dysfunction and death of susceptible neuronal populations. Increasing evidence has demonstrated that sustained neuroinflammation and activation of innate immune complexes underlie neurodegeneration, worsening disease progression and outcomes. Sterile inflammation (which occurs in the absence of infection) can be triggered by neurodegenerative disease-associated misfolded proteins. These studies highlight the need to decipher the complexities of innate immune signaling mechanisms and their contribution to neuropathology. In this review, we focus on major neurodegenerative diseases that have a well-documented neuroinflammatory component: Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, and frontotemporal dementia. In the context of these diseases, we discuss recent advances in innate-immune mechanisms that have been demonstrated to partake in disease progression and neurodegeneration. These include evolutionarily conserved innate-immune signaling complexes whose uncontrolled activation amplifies neurodegeneration, damaging lipid droplets that accumulate within myeloid cells and prevent their ability to clear toxic protein aggregates, as well as genome-wide studies-implicated genes/proteins. The individual and/or concerted actions of these pathways could be leveraged to rationally target the pathogenesis or progression of neurodegenerative diseases.\n\nID: 41265623\nTitle: Oxymatrine regulates microglia to produce IFN-\u03b2 by activating the STING/TBK1/IRF3 pathway against experimental autoimmune encephalomyelitis.\nAbstract: Oxymatrine is an alkaloid with the property of immunomodulation. Recent studies have demonstrated that oxymatrine inhibits experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), by promoting the production of interferon-\u03b2 (IFN-\u03b2). However, the mechanism through which oxymatrine regulates the production of IFN-\u03b2 remains unclear. The aim of this study was to investigate the pharmacological effects and related molecular mechanisms of oxymatrine in the treatment of EAE through in vivo and in vitro experiments. Oxymatrine alleviated neurological dysfunction, demyelination, and inflammation in EAE mice. It reduced microglia/macrophage infiltration and polarization, lowered pro-inflammatory cytokine levels (iNOS, TNF-\u03b1), and enhanced the expression of IL-10 and IL-27. Additionally, oxymatrine upregulated the STING/TBK1/IRF3 signaling pathway in EAE mice, promoting IFN-\u03b2 production by microglia. Similarly, in LPS-induced BV2 cells, oxymatrine suppressed inflammatory factors and activated the STING/TBK1/IRF3 pathway to enhance IFN-\u03b2 production. Notably, treatment with the STING inhibitor, C176, reversed these effects in both EAE mice and LPS-induced BV2 cells, confirming the pathway's critical role in the mechanism of oxymatrine therapy. Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events. This study identifies a novel anti-EAE mechanism of oxymatrine: promoting IFN-\u03b2 production in microglia by activating the STING/TBK1/IRF3 pathway. However, it lacks clinical sample verification. If validated later, oxymatrine may provide a more economical, convenient endogenous IFN-\u03b2 induction regimen for MS patients.\n\nID: 41073405\nTitle: Extracellular vesicles derived EBV tegument protein BRRF2 suppresses cGAS phase separation to promote anti-viral innate immune evasion.\nAbstract: Viral strategies to antagonize the robust host innate immune response have a major function in the pathogenicity of viral infection and virus-associated cancers. Epstein-Barr virus (EBV) infection causes infectious mononucleosis (IM) and several human cancers. While latent EBV can reactivate in some nasopharyngeal carcinoma (NPC) cells, the impact of EBV reactivation on the anti-viral innate immune and immunotherapy response of NPC patients remains incompletely understood. Here, we reveal the function of the EBV-encoded BRRF2 protein as a pivotal regulator of the host immune system. We show that BRRF2, which is secreted via extracellular vesicles (EVs) from NPC cells undergoing EBV reactivation, specifically targets macrophages. It disrupts the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway, which is crucial for innate immunity. BRRF2 inhibits the enzymatic activity of cGAS by interfering with the interaction of cGAS with dsDNA and reducing cGAS-DNA phase separation. Notably, our research shows a marked increase in the levels of BRRF2+ EVs in the bloodstream of NPC patients, which is closely associated with a diminished response to immunotherapy. By identifying BRRF2 as a potential biomarker for immunotherapy resistance, our findings provide deeper insight into the contribution of EBV to viral immunology and suggest further avenues for therapeutic intervention to increase the efficacy of immunotherapy.\n\nID: 41063265\nTitle: Early antiviral treatment following gammaherpesvirus-68 infection of the central nervous system prevents subsequent multiple sclerosis-like disease.\nAbstract: Growing evidence indicates that Epstein-Barr virus (EBV), a gammaherpesvirus, plays a central role in the pathogenesis of multiple sclerosis (MS). The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development.\n\nID: 40913578\nTitle: Nanoparticles Induce Protein Corona Conformational Change to Reshape Intracellular Interactome for Microglial Polarization.\nAbstract: Nanoparticles bind to proteins in cells selectively and form a protein corona around them. However, the mechanisms of protein conformational changes underlying the interactions between nanoparticles and protein coronas remain poorly understood. In this study, we prepared small molecule self-assembled nanoparticles (Aloin NPs) as a research tool to investigate the allosteric mechanism of protein coronas. Aloin NPs showed a propensity to capture multiple proteins in cells. In particular, Aloin NPs specifically bound to myotrophin (MPTN) as a major protein corona through a multivalent hydrogen bond-mediated nanoprotein interface. Molecular modeling and hydrogen-deuterium exchange mass spectrometry (MS) demonstrated that Aloin NPs promoted a conformational rearrangement of MPTN via a 'finger-unclasping' pattern. We then adapted the APEX2 proximity labeling strategy to investigate the conformation-dependent changes in the MPTN interactome and identified peroxiredoxin 6 (PRDX6) as a key substrate protein of MPTN in microglia. Additionally, we observed that MPTN conformational change-dependent PRDX6 release protected the mitochondrial membrane by reducing reactive oxygen species. Consequently, Aloin NPs effectively inhibited the release of mitochondrial DNA to block the downstream cGAS-STING signaling pathway, thereby reprogramming microglial polarization. In translational medicine, Aloin NPs play a role in protecting neurons from microglia-induced inflammatory injury with no significant adverse effects, ultimately improving Parkinson's disease-associated symptoms. Taken together, our study provides insights into the molecular mechanisms by which nanoparticles regulate the conformational change of protein coronas for human disease therapy.\n\nID: 40906893\nTitle: LRRK2 kinase activity restricts NRF2-dependent mitochondrial protection in microglia.\nAbstract: Mounting evidence supports a critical role for central nervous system (CNS) glial cells in neuroinflammation and neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's Disease (PD), Multiple Sclerosis (MS), as well as neurovascular ischemic stroke. Previously, we found that loss of the PD-associated gene leucine-rich repeat kinase 2 (Lrrk2) in macrophages, peripheral innate immune cells, induced mitochondrial stress and elevated basal expression of type I interferon (IFN) stimulated genes (ISGs) due to chronic mitochondrial DNA engagement with the cGAS/STING DNA sensing pathway. Here we report that loss of LRRK2 results in a paradoxical response in microglial cells, a CNS-specific macrophage population. In primary murine microglia and microglial cell lines, loss of Lrrk2 reduces tonic IFN signaling leading to a reduction in ISG expression. Consistent with reduced type I IFN, mitochondria from Lrrk2 KO microglia are protected from stress and have elevated metabolism. These protective phenotypes involve upregulation of NRF2, an important transcription factor in the response to oxidative stress and are restricted by LRRK2 kinase activity. Collectively, these findings illustrate a dichotomous role for LRRK2 within different immune cell populations and give insight into the fundamental differences between immune regulation in the CNS and the periphery.\n\nID: 40817248\nTitle: TRIM6 ablation reverses ICB resistance in MSS gastric cancer by unleashing cGAS-STING-dependent antitumor immunity.\nAbstract: Gastric cancers are classified into four molecular subtypes according to The Cancer Genome Atlas (TCGA) classification: Epstein-Barr virus-positive (EBV-positive), microsatellite instability-high (MSI-H), chromosomal instability (CIN), and genomically stable (GS). Unlike MSI-H gastric cancer, GS and CIN subtypes exhibit immunologically inert microenvironments and demonstrate minimal response to immune checkpoint blockade (ICB), necessitating novel strategies to overcome immunotherapy resistance. Through weighted gene co-expression network analysis (WGCNA), we identified the E3 ubiquitin ligase TRIM6 as inversely associated with MSI-H status. TRIM6-knockout murine models and subcutaneous tumors were subjected to flow cytometry, RNA sequencing, immunoblotting, and ubiquitination assays to characterize tumor-infiltrating lymphocytes (TILs), pathway activation, and TRIM6-mediated regulation of the cGAS-STING axis. Hypermethylation-mediated TRIM6 downregulation distinguished MSI-H from microsatellite stable (MSS) gastric cancers. Clinically, TRIM6 expression inversely correlated with cytotoxic T lymphocyte (CTL) infiltration and anti-PD-1/PD-L1 therapeutic efficacy. Mechanistically, TRIM6 catalyzed K27-linked polyubiquitination of cGAS, triggering its proteasomal degradation and consequent suppression of the cGAS-STING pathway. TRIM6 ablation enhanced CD8+ T lymphocytes infiltration via cGAS-mediated innate immune response and synergized with anti-PD-L1 therapy in MSS gastric tumors. Our results elucidate TRIM6-mediated suppression of antitumor immunity as a novel mechanism underlying ICB resistance in MSS gastric cancer, positioning TRIM6 as both a predictive biomarker and therapeutic target for immunologically cold subtypes.\n\nID: 40808412\nTitle: cGAS-STING axis: A central regulator of neural homeostasis and neuroinflammatory pathogenesis.\nAbstract: An increasing amount of evidence shows that type I interferon response, which is induced by cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) and stimulator of interferon genes (STING) is closely associated with health and neuroinflammatory diseases. Abnormal activation or loss of control of the cGAS-STING axis affects the development of neuroinflammation. Thus, we examined its role in major neurological diseases, including traumatic brain injury, Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, herpes simplex encephalitis, and ataxia-telangiectasia. Additionally, targeted intervention of the cGAS-STING axis to control neuroinflammation and treat related diseases has become the focus of current clinical research. This article describes the development of cGAS inhibitors and small molecules that target the cGAS-STING axis and explores the potential applications of STING inhibitors and agonists in clinical research. In summary, the cGAS-STING axis may impact neurological diseases more than a single protein or gene. Future studies should focus on elucidating the functional dynamics and regulatory networks of this axis and delineating its crosstalk with other signaling cascades. These investigations will provide mechanistic insights for developing targeted therapeutic strategies for associated disorders and potentially facilitate drug repurposing across diverse disease contexts.\n\nID: 40686188\nTitle: Type I Interferon Signaling Augments Autoimmunity in Neuromyelitis Optica Spectrum Disorder.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by anti-aquaporin 4 (AQP4) antibody-mediated astrocyte damage and subsequent demyelination. Prior attempts to treat NMOSD with interferon-beta (IFN-\u03b2), a disease-modifying therapy for multiple sclerosis, resulted in worsening of disease activity, with an unknown mechanism. Here, robust activation of the cGAS-STING-IFN-I signaling pathway is identified\u00a0in myeloid cells in both the periphery and central nervous system. The abnormal IFN-I response gives rise to an increase in the number of AQP4 antigen-specific autoreactive T cells. Sting deficiency can significantly blunt the activation of AQP4-specific T cells, as well as the IFN-I activity in microglia, and attenuate astrocyte damage. Consequently, the clinical manifestation of NMOSD is ameliorated in a passive transfer mouse model of NMOSD. Further, treatment with STING inhibitor H151 alleviates the severity of NMOSD mouse models. These findings uncover the cGAS-STING-IFN-I pathway in promoting autoreactive T cells and establish a foundation for inhibiting this pathway as a new therapeutic revenue for NMOSD.\n\nID: 40613364\nTitle: Stimulator of Interferon Genes (STING)-Type I Interferon Signaling: Bridging Immunity and Pain.\nAbstract: Interferons (IFNs) are cytokines with diverse functions, possessing antiviral, antiproliferative, and immunomodulatory effects. IFN-\u03b1 and IFN-\u03b2, key members of the type I interferon (IFN-I) family, are widely used in the treatment of diseases such as hepatitis and multiple sclerosis. In the nervous system, microglia, astrocytes, and neurons express IFN-I receptors. Beyond their classical transcriptional roles, IFN-Is can suppress neuronal activity and synaptic transmission through nongenomic mechanisms, producing potent analgesic effects. However, IFN-Is are active in signaling pathways such as phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK), and the MAPK-interacting serine/threonine-protein kinase (MNK)-eukaryotic initiation factor 4E (eIF4E) pathway, which can sensitize peripheral nociceptors and contribute to nociceptive responses. This narrative review explores recent advances in understanding the roles of IFN-I and the cyclic-GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling cascade in acute and chronic nociceptive responses, which are increasingly recognized but remain a subject of debate. Recent studies suggest that the STING-IFN-I pathway has complex, stage-dependent effects on nociception. In the middle to late stages of the nociceptive response, this pathway can activate signal transducer and activator of transcription (STAT) signaling, as well as microglial mediated STING pathways and tumor necrosis factor (TNF) receptor-associated factor (TRAF) family member-associated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB activator) collectively referred to as TANK. These pathways increase pro- and anti-inflammatory cytokine production, promote microglial M1 polarization, and inhibit endoplasmic reticulum-phagy (ER-phagy) in the central nervous system (CNS). These mechanisms contribute to central sensitization while modulating the analgesic effects of IFN-Is. Thus, the STING-IFN-I pathway plays a dual role in nociception, with both pro-nociceptive and analgesic effects that are dependent on the stage of the nociceptive response. Understanding the differential roles of STING-IFN-I signaling in nociceptors under physiological and pathological conditions could pave the way for the development of targeted nociceptive response management therapies.\n\nID: 40526717\nTitle: Sp140L functions as a herpesvirus restriction factor suppressing viral transcription and activating interferon-stimulated genes.\nAbstract: Herpesviruses, including Epstein-Barr virus (EBV) - a human oncogenic virus and essential trigger of multiple sclerosis - must bypass host DNA-sensing mechanisms to establish lifelong, latent infection. Therefore, herpesviruses encode viral proteins to disrupt key host factors involved in DNA sensing and viral restriction. The first viral latency protein expressed, EBNA-LP, is essential for transformation of na\u00efve B cells and establishment of viral gene expression, yet its role in evading host defenses remains unclear. Using single-cell RNA sequencing of EBNA-LP Knockout (LPKO)-infected B cells, we reveal an antiviral response landscape implicating the \"speckled proteins\" as key cellular restriction factors countered by EBNA-LP. Specifically, loss of Sp100 or the primate-specific Sp140L reverses the restriction of LPKO, suppresses a subset of canonically interferon-stimulated genes, and restores transcription of essential latent viral genes and cellular proliferation. Notably, we also identify Sp140L as a restriction target of the herpesvirus saimiri ORF3 protein, implying a role for Sp140L in immunity to other diverse DNA viruses. This study reveals Sp140L as a restriction factor that we propose links sensing and transcriptional suppression of viral DNA to an Interferon-independent innate immune response, likely relevant to all nuclear DNA viruses.\n\nID: 40399572\nTitle: Innate Immune Recognition of EBV.\nAbstract: Epstein-Barr virus (EBV) is a very successful human pathogen, with ~95% seroprevalence worldwide (Mentzer et al, Nat Commun 13:1818, 2022). If contracted in early childhood, EBV infection is typically asymptomatic; however, infections in adolescence and adulthood can manifest as infectious mononucleosis (IM). The innate immune response is the first line of defense, and its function is critical for controlling EBV infection. During EBV infection, components of the virus, known as pathogen-associated molecular patterns (PAMPs), are recognized by germline-encoded pattern recognition receptors (PRRs). PRRs are found on both non-immune and immune cells including antigen-presenting cells, such as macrophages, monocytes, dendritic cells, natural killer (NK), and mast cells. PRRs are also found on B cells and epithelial cells, the primary targets of EBV infection. Without immune surveillance, EBV can transform cells inducing various malignancies. Conversely, a prolonged innate immune response can lead to chronic inflammation which increases the likelihood of cancer. This review discusses innate immune recognition of EBV and its associated diseases.\n\nID: 40275354\nTitle: Targeting microglia-Th17 feed-forward loop to suppress autoimmune neuroinflammation.\nAbstract: Microglia and Th17 cells are the major immunopathogenic cells in multiple sclerosis and its animal model of immune aspects, experimental autoimmune encephalomyelitis (EAE). While studies have highlighted the distinct roles of microglia and Th17 cells in EAE, it remains unclear whether microglia, as potential professional antigen-presenting cells, activate and stabilize the effector program of EAE-pathogenic Th17 cells in vivo; and if so, whether the Th17 could in turn reinforce the active state of the microglia. Our data demonstrate in an array of mouse models, including active/passive-EAE and transgenic mice, a microglia-Th17 feed-forward activation loop drives EAE disease progression through a mechanism dependent on both MHC-II, proinflammatory cytokines, inflammatory chemokines as well as STING\u2192NF-\u03baB pathway in the microglia and effector cytokines produced by the pathogenic Th17 cells. We also captured and identified the molecular properties of the feed-forward loop, which are two-cell entities of microglia-Th17, and proved them as the functional units of antigen presentation and bi-directional activation between the two cell types. Moreover, ACT001, an orphan drug to treat glioblastoma, disrupts this feed-forward activation loop by inhibiting the STING\u2192NF-\u03baB pathway in microglia, thereby alleviating EAE. These findings emphasize the importance of interactions and bi-directional activations between microglia and Th17 in the autoimmune neuroinflammation, and provide rationale for further investigation on ACT001 as therapeutic option for autoimmune inflammatory diseases driven by similar mechanisms.\n\nID: 40079734\nTitle: EBV enhances immunotherapy sensitivity in intrahepatic cholangiocarcinoma through cGAS-STING pathway activation.\nAbstract: The absence of representative Epstein-Barr virus-associated intrahepatic cholangiocarcinoma (EBVaICC) cell lines has limited our understanding of the molecular and immunological characteristics of this cancer subtype. We reviewed patients with metastatic cholangiocarcinoma at Sun Yat-sen University Cancer Center from January 2015 to August 2023. Among them, 22 patients with EBVaICC and 66 patients with non-EBVaICC who received anti-PD1 treatment were included. Additionally, 2 EBV-positive ICC cell lines, RBE-EBV and HuH28-EBV, were developed through cell-to-cell infection. Stable EBV infection and responsiveness to viral reactivation were confirmed. Transcriptomic and bioinformatics analyses were performed, and in vitro experiments examined the immune effects of EBV-positive ICC. Key immune-related genes and cytokines were validated by reverse transcription quantitative polymerase chain reaction and ELISA in cell lines and patient plasma samples. In this study, we found that patients with EBVaICC showed enhanced immune responses and improved overall and progression-free survival compared to patients with non-EBVaICC. We first successfully established and validated 2 EBV-positive ICC cell lines (RBE-EBV and HuH28-EBV). These cell lines were confirmed for stable EBV infection and displayed responsiveness to viral reactivation, making them suitable for future studies. Transcriptomic analyses and in vitro studies revealed that EBV activated the cGAS-STING pathway, resulting in MHC-I upregulation and CXCL10 secretion in ICC cells, which collectively enhanced CD8+ T cell chemotaxis and cytotoxicity. Furthermore, ELISA analysis showed higher plasma levels of CXCL10 and IFN-\u03b3 in patients with EBVaICC, suggesting a potential role for EBV in enhancing immunotherapy sensitivity in this subtype. The established EBV-positive ICC cell lines revealed enhanced immunogenicity driven by cGAS-STING pathway activation, providing valuable models for future research and insights into the mechanisms of improved immunotherapy sensitivity in EBVaICC.\n\nID: 39766068\nTitle: Epstein Barr Virus (EBV) Latent Membrane Protein 1 (LMP-1) Regulates Functional Markers in Intermediate and Non-Classical Monocytes.\nAbstract: Background: The Epstein-Barr virus (EBV) infects more than 90 percent of the human population. In pediatric patients, the innate immune response against EBV primary infection plays a key role. Monocytes and macrophages can have distinct functions depending on the microenvironment surrounding them. At least three monocyte subpopulations can be differentiated depending on membrane protein expression: classical (C, CD14++CD16-), intermediate (I, CD14++CD16+), and non-classical (NC, CD14+CD16++). They also modulate T and B lymphocyte activation/inhibition through the expression of costimulatory molecules such as CD80, CD86, and PD-L1. Yet, little is known about monocytes' role in EBV infection. Methods: Peripheral blood and tonsil biopsies of EBV primary infected (PI) patients, healthy carriers (HCs), and patients undergoing reactivation (R) were studied. Results: Classical monocytes prevailed in all infectious statuses. Tonsillar CD163 positively correlated with CD163 expression in NC monocytes in HCs. PD-L1+ cells in the tonsil positively correlated with PD-L1 expression in NC monocytes. LMP-1 viral latent protein presented a positive correlation with PD-L1, CD163, and CD206 expression in the NC subpopulation. Conclusions: Our results evidence the predominant role of I and NC monocytes' response against EBV infection. Furthermore, the viral oncoprotein LMP-1 could be involved in the expression of regulatory proteins in I and NC monocytes.\n\nID: 42387516\nTitle: HSV-1 reactivation as an emergent property of neuronal stress: implications for traumatic brain injury.\nAbstract: Herpes simplex virus type 1 (HSV-1) establishes lifelong latency in neurons, with reactivation driven by multiple molecular, cellular, and systemic stressors. While several individual mechanisms of reactivation have been well characterized, there are potentially other unresolved vulnerabilities that drive HSV-1 reactivation. Traumatic brain injury (TBI) has emerged as a potential trigger of HSV-1 reactivation and represents a complex and clinically relevant perturbation that disrupts neuronal homeostasis, immune surveillance, and inflammatory signaling, processes that are also central to HSV-1 latency and reactivation. However, the mechanisms linking TBI to HSV-1 reactivation remain poorly understood.In this review, we examine whether known mechanisms of TBI-induced cellular stress overlap with pathways implicated in HSV-1 latency and reactivation. We synthesize shared mechanisms, including stress signaling, neuroinflammation, and immune dysregulation during TBI that may create conditions permissive for HSV-1 reactivation in the injured brain. This integrated perspective reframes TBI as a context in which established drivers of HSV-1 reactivation converge and may increase reactivation susceptibility.We propose that HSV-1 reactivation is an emergent property of dysregulated neural systems and that TBI may engage many of these processes. In this framework, viral reactivation is inseparable from the broader neuronal and systemic context in which it occurs. This perspective highlights the importance of integrating neural state, injury, and immune dynamics into models of HSV-1 latency and reactivation. Advancing this multidimensional view will be critical for developing therapeutic strategies that not only suppress viral reactivation but also address neuroinflammation following brain injury.\n\nID: 42370935\nTitle: Chronic hyperinsulinemia accelerates adipose senescence via mitochondrial dysfunction and cGAS-STING signalling.\nAbstract: Prediabetes and Type 2 Diabetes represent major global health challenges and have escalated to pandemic levels. Adipose tissue functions as a critical endocrine organ, playing a central role in maintaining glucose homeostasis during fasting, feeding, and stress responses. In this study, we demonstrated that prolonged chronic hyperinsulinemic stress increases the burden of senescent adipocytes, accompanied by activation of the cGAS-STING signalling pathway. Chronic hyperinsulinemia-induced insulin-resistant 3T3-L1 and human mesenchymal stem cell-derived adipocytes exhibited elevated senescence-associated phenotypes, mitochondrial dysfunction and impaired cellular energetics. Notably, we found that mitochondrial DNA leakage triggered the cGAS-STING pathway in insulin-resistant adipocytes and mouse models. Temporal analysis revealed that mitochondrial dysfunction was detectable at earlier stages of chronic insulin exposure, preceding activation of the cGAS-STING pathway and senescence-associated markers, supporting a progressive model of cellular dysfunction. This phenomenon was also observed in adipose depots of individuals with Type 2 diabetes, underscoring the translational relevance of our findings. Targeting cGAS or STING, either pharmacologically or through genetic silencing, significantly reduced inflammatory and senescence-related features in hyperinsulinemia-induced insulin-resistant 3T3-L1 adipocytes. Furthermore, attenuation of senescence treatment with the combination of Dasatinib and Quercetin alleviated mitochondrial stress and associated adipose dysfunction. Collectively, our findings support a model in which prolonged hyperinsulinemic stress induces early mitochondrial dysfunction, followed by activation of cGAS-STING signalling and the subsequent emergence of adipocyte senescence-associated phenotypes, contributing to adipose tissue dysfunction in insulin resistance and Type 2 Diabetes.\n\nID: 42353049\nTitle: Integrative Transcriptomics Uncovers IFN-\u03b2 Signature and IFITM3 as Putative Molecular Mediator in MS.\nAbstract: Neuroinflammation in multiple sclerosis (MS) is driven by the infiltration of myelin-reactive T cells into the central nervous system (CNS). Interferon-\u03b2 (IFN-\u03b2) is one of the earliest disease-modifying treatments (DMTs) approved for MS and remains widely used in special populations (pregnant and elderly patients) owing to its favorable safety profile. However, the exact mechanism of action of this drug and reliable biomarkers of treatment response remain unclear. Transcriptomic profiling and data integration approaches offer powerful tools for investigating complex patterns of regulation and molecular mechanisms underlying therapeutic efficacy. In this study, we performed an integrative analysis of openly available transcriptomic datasets to characterize IFN-\u03b2-induced gene expression changes in MS patients. By combining data from large independent cohorts, we identified a 43-gene transcriptional signature consistently associated with IFN-\u03b2 treatment across disease stages, including progressive MS. To explore the relevance of this signature, we cross-referenced the 43-gene signature with publicly available expression quantitative trait loci (eQTL) datasets to determine whether these genes could be influenced by known MS-associated risk variants highlighting Interferon-Induced Transmembrane Protein 3 (IFITM3) as a candidate molecular mediator of MS. This integrative approach provides new insights into IFN-\u03b2-driven immune modulation and supports the development of therapeutic strategies for MS.\n\nID: 42352365\nTitle: Infectious Agents in Multiple Sclerosis: Viral Triggers, Antibody-Mediated Autoimmunity, and Parasitic Immunomodulation.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system characterized by demyelination, neuroinflammation, and progressive neurodegeneration. While there is a small component of genetic susceptibility to MS risk, environmental factors, including infectious exposures, are gaining increased recognition as playing a critical role in MS initiation and progression. Viral infections, especially by Epstein-Barr virus (EBV), have emerged as strong candidates and triggers of MS symptoms, through antibody-mediated molecular mimicry and B-cell dysregulation. In contrast, parasitic infections, including helminths and select protozoa, appear to exert neuroprotective effects by skewing immune responses toward regulation and tolerance. In this review, we examine antibody-driven mechanisms by which viral pathogens promote autoimmunity in MS and contrast these with parasite-induced immunoregulatory pathways that suppress pathogenic inflammation. We further discuss diagnostic and therapeutic implications, highlighting how insights from infectious immunology may inform novel strategies for MS treatment.\n\nID: 42346242\nTitle: Radiobiotherapy in Osteosarcoma: A State-Based Educational Framework for Strategy Selection and Trial Design.\nAbstract: Background: Osteosarcoma remains a biologically complex and clinically challenging malignancy, with survival gains plateauing despite decades of multimodal therapy incorporating surgery and cytotoxic chemotherapy. Unlike cancers in which mutation-centric precision oncology has yielded transformative advances, osteosarcoma is characterized by profound structural variation, copy number alteration dominance, and dynamic clonal evolution, limiting the effectiveness of single-target approaches. These realities motivate alternative strategy-level frameworks that better align treatment selection with evolving disease behavior. Methods: This narrative educational review synthesizes contemporary evidence from osteosarcoma biology, radiobiology, and translational oncology to propose a state-based framework for integrating radiotherapy-particularly stereotactic body radiotherapy (SBRT/SABR) and spatially fractionated radiotherapy (SFRT)-into osteosarcoma management and clinical trial design. Rather than relying solely on static anatomic stage, this framework emphasizes clinically actionable, time-varying state variables, including disease burden patterns (localized, oligometastatic, polymetastatic), tempo of progression, prior systemic response, and feasibility of complete local control. Results: Within this context, radiotherapy is presented not only as a local control modality but also as a hypothesis-generating biologic intervention, capable of perturbing tumor vasculature, inflammatory signaling, innate DNA-sensing pathways, and immune/myeloid programs in a dose-, fractionation-, and spatial-distribution-dependent manner. The review critically examines both the potential opportunities (e.g., local eradication, immune modulation) and limitations (e.g., rarity of abscopal responses, risk of unintended systemic signaling) of radiobiotherapy combinations, emphasizing the need for cautious interpretation and prospective validation. Conclusions: Finally, the article outlines practical implications for state-stratified, biomarker-embedded clinical trials, highlighting endpoints beyond conventional response criteria, including circulating tumor DNA dynamics, immune and myeloid signatures, and long-term patterns of disease progression. Overall, this review frames radiobiotherapy as an educational and investigational paradigm intended to support rational hypothesis generation, multidisciplinary decision-making, and learning-oriented trial designs in osteosarcoma, rather than as definitive clinical guidance.\n\nID: 42340456\nTitle: Viral Infections and Neurodegenerative Diseases: Reinterpreting the Crosstalk Through a Dual-Role Lens.\nAbstract: Neurodegenerative diseases (NDDs) are multifactorial disorders with increasing evidence implicating viral infections in their pathogenesis. However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\n\nID: 42335641\nTitle: Delphinidin targets voltage-dependent anion channel 1 to inhibit ferroptosis and protect against retinal photochemical damage.\nAbstract: The molecular basis of retinal photochemical damage remains incompletely understood, limiting the development of targeted therapeutic strategies. Delphinidin, an anthocyanidin with reported protective effects, represents a promising candidate, but its direct molecular target and mechanism of action are unclear. The molecular target of delphinidin was identified using Activity-Based Protein Profiling (ABPP), DARTS-MS, SPR, and CETSA. Its functional effects were investigated in 661 W photoreceptor cells and in a light-induced retinal damage model in Sprague-Dawley rats. Protein carbonylation was assessed via an alkynylaniline probe, and Voltage-Dependent Anion Channel 1 (VDAC1) oligomerization was examined by chemical crosslinking. Mitochondrial function, cGAS-STING pathway activation, and ferroptosis markers were evaluated to delineate the underlying mechanism. VDAC1 was identified as a direct target of delphinidin. Light exposure induced VDAC1 carbonylation and oligomerization, leading to mitochondrial dysfunction characterized by cytochrome c release and mitochondrial DNA (mtDNA) leakage into the cytosol. Cytosolic mtDNA activated cGAS-STING pathway, which in turn promoted loss of the ferroptosis suppressor GPX4 and triggered ferroptosis. Delphinidin interrupted this cascade by binding to VDAC1 and inhibiting its carbonylation and oligomerization, thus limiting mtDNA leakage, attenuating cGAS-STING activation, preserving GPX4 abundance, and inhibiting ferroptosis. In vivo, delphinidin intervention conferred significant protective effects, as evidenced by preservation of retinal histoarchitecture and reduced oxidative damage and ferroptosis, CONCLUSION: This study identifies a novel mechanistic axis in RPD linking VDAC1 dysregulation to mtDNA-driven innate immune activation and ferroptosis. It further establishes delphinidin as a direct VDAC1 targeting compound and highlights its therapeutic potential for the prevention of RPD.\n\nID: 42333016\nTitle: STING Modulating ER-Phagy in the Prelimbic Cortex Neurons Contributed to Neuropathic Pain and Emotional Comorbidity.\nAbstract: Our previous data suggested that autophagy is crucial for neuropathic pain. The different cell types and varying degrees of regulation of STING may lead to a paradoxical effect on pain and emotions in the neuropathic pain model. Up to now, whether STING modulates neuropathic pain in PrL neurons via ER-phagy is still unknown. In this study, we investigated the effect of ER-phagy in the prefrontal cortex (PrL) on neuropathic pain. We administered 4-phenylbutyric acid, tunicamycin, 3-methyladenine, and rapamycin to evaluate the interaction between endoplasmic reticulum (ER) stress and autophagy in the PrL of SNL (spinal nerve ligation). We injected AAV to investigate whether ER-phagy modulated pain and emotional behaviors. We further explored whether STING and its pathway as a modulation target for ER-phagy to participate in the pain process. We injected 2'3-cGAMP and RU521 to modulate the cGAS/STING pathway in ER-phagy in SNL mice. Moreover, we modulated STING expression and regulated the levels of ER-phagy and the interaction between STING and LC3 in neurons through PrL AAV injections. The data indicated that ER-phagy alleviated the excessive ER stress induced by SNL in PrL through the cGAS/STING pathway. Regulating ER-phagy in PrL neurons through AAV tools altered pain and emotion-related behaviors. In addition, regulating STING in PrL neurons altered the comorbidity of pain and emotion. Importantly, the binding interaction between STING and LC3 in PrL neurons provides a novel target for PrL ER-phagy. Enhanced ER-phagy of PrL neurons provides analgesic, anti-anxiety, and antidepressant effects through modulating STING in SNL mice.\n\nID: 42296122\nTitle: Central Nervous System T-cell immune architecture, and not HIV burden, tracks with cognition under long-term viral suppression.\nAbstract: Despite effective antiretroviral therapy, HIV persists in the central nervous system (CNS) and may contribute to neuroinflammation and cognitive impairment. How viral persistence, immune responses, and regional CNS T-cell architecture relate to cognitive functioning remains unclear. We performed a cross-sectional, multi-compartmental immune-genomic study in 12 people with HIV on long-term viral suppression enrolled in the Last Gift rapid autopsy program. Quantitative HIV reservoir measures (total-episomal DNA, unspliced-multiply spliced RNA) and paired \u03b1\u03b2 T-cell receptor repertoire (TCRR) sequencing were performed in peripheral blood mononuclear cells and five CNS regions: hippocampus, frontal motor cortex, basal ganglia, occipital cortex, and spinal cord. Cognitive performance was assessed within one year of death. Tissue-resolved associations between cognition and HIV reservoir, TCRR architecture (richness, diversity, clonality), and pathogen-specific T-cell clonotypes (HIV, CMV, EBV, and riboflavin derivatives) were evaluated using participant-clustered multivariable models. False discovery rate was applied. HIV DNA and RNA were detectable across all tissues but were not associated with cognitive performance or TCRR metrics. Peripheral TCRR architecture was unrelated to cognition, whereas higher TCRR richness and diversity in the hippocampus and spinal cord were associated with worse verbal, motor, and attention/working memory scores. Higher TCRR richness in the spinal cord was also associated with better recall. T-cell receptor clonotype frequency distributions differed across CNS regions, consistent with regional immune compartmentalization. Epitope-inference analyses revealed pathogen-dependent associations: higher number of HIV-specific T-cell clonotypes in the basal ganglia was associated with better global and attention/working memory scores, whereas riboflavin derivative-specific clonotypes in frontal motor cortex were associated with better motor performance. CMV-specific clonotypes showed nominal associations with worse learning and memory. CNS-localized T-cell receptor architecture and antigenic imprinting related more closely to neurocognitive variability than quantitative measures of HIV persistence under viral suppression, highlighting regional specialization of T-cell responses as a potential correlate of brain health.\n\nID: 42295377\nTitle: Emerging therapeutic strategies in multiple sclerosis: a focus on innovative and targeted approaches.\nAbstract: Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system marked by damage to myelin and nerve cells. Current treatments help control inflammation but have limited success in progressive stages and repairing nerve damage. This review aims to summarize new therapies for MS that target both inflammation and neurodegeneration beyond traditional immunosuppressive drugs. We conducted a thorough literature search to summarize key findings from original studies, including clinical trials investigating novel MS treatments such as Bruton's tyrosine kinase (BTK) inhibitors, CAR T-cell therapy, vaccines targeting Epstein-Barr virus (EBV) and specific antigens, drugs promoting remyelination, monoclonal antibodies, stem cell therapy, sphingosine-1-phosphate receptor modulators, cytokine blockers, gut microbiome interventions, and nanotechnology-based drug delivery. Emerging therapeutic strategies in MS increasingly target mechanisms beyond conventional immunosuppression, including B-cell and microglial modulation, immune tolerance induction, remyelination, cytokine signaling, microbiome regulation, and enhanced central nervous system drug delivery. BTK inhibitors and S1P receptor modulators demonstrated anti-inflammatory activity in clinical trials, although some agents failed to show superiority over established therapies. Cell-based therapies, including CAR T-cell therapy and stem cell transplantation, showed early promise in refractory disease but remain limited by safety concerns and insufficient long-term data. Remyelination-promoting agents and EBV-targeted immunotherapies demonstrated encouraging preliminary findings; however, many approaches remain in preclinical or early-phase clinical stages. Nanotechnology-based delivery systems and microbiome-directed therapies represent emerging areas with potential translational relevance. Emerging therapies in MS reflect a growing shift toward mechanism-based and potentially personalized therapeutic strategies. Although several approaches demonstrate promising preclinical and early clinical results, many remain investigational, and further large-scale studies are required to establish long-term efficacy, safety, and clinical applicability.\n\nID: 42278492\nTitle: Sex Differences in Mitochondrial Function: Endocrine Regulation, Immunometabolic Signaling, and Implications for Health and Disease.\nAbstract: Mitochondria are central regulators of cellular bioenergetics, redox balance, and signaling pathways that integrate metabolic and immune responses. Emerging evidence indicates that biological sex is an important determinant of mitochondrial function, in part through the regulatory effects of sex hormones on mitochondrial biogenesis, oxidative phosphorylation, reactive oxygen species production, and quality control mechanisms. Estrogen, testosterone, and progesterone differentially modulate mitochondrial dynamics, substrate utilization, antioxidant capacity, and immune signaling, resulting in distinct mitochondrial phenotypes that may influence disease susceptibility across the lifespan. In this review, we synthesize current knowledge on the mechanistic basis of sex differences in mitochondrial function and highlight mitochondria as key mediators linking endocrine signaling to immunometabolic regulation. We discuss how mitochondrial-derived signals, including mitochondrial reactive oxygen species, mitochondrial DNA release, and cardiolipin exposure, activate inflammatory pathways such as NF-\u03baB, cGAS-STING, and NLRP3 inflammasome signaling. These pathways may contribute to chronic inflammation, gut barrier dysfunction, and systemic metabolic disruption. We further examine the impact of major endocrine transitions, including pregnancy, the postpartum period, menopause, and androgen imbalance in conditions such as polycystic ovary syndrome, on mitochondrial function and disease risk. Particular emphasis is placed on the gastrointestinal tract as a metabolically active and mitochondria-dependent interface, where mitochondrial dysfunction may contribute to epithelial barrier disruption, microbial dysbiosis, and systemic inflammation. Finally, we discuss emerging therapeutic strategies targeting mitochondrial function, including exercise, hormone-based therapies, mitochondria-targeted antioxidants, and interventions aimed at improving mitochondrial quality control. Understanding sex-specific mitochondrial regulation may provide a framework for improved endocrine stratification, mitochondrial phenotyping, and precision medicine approaches across diverse clinical contexts.\n\nID: 42277187\nTitle: Type I interferon signature does not correlate with disease activity in Blau syndrome.\nAbstract: Blau syndrome is a rare autoinflammatory disorder caused by NOD2 mutations, characterized by granulomatous arthritis, uveitis, and dermatitis. While type I interferon signatures are biomarkers in several autoinflammatory diseases, their role in Blau syndrome remains unclear. We assessed the interferon score in 11 patients with Blau syndrome and correlated it with disease activity. Our results demonstrate that type I interferon signatures were detected in only a minority of patients and showed no significant correlation with clinical disease activity, inflammatory markers, or treatment response. These findings suggest that type I interferon signatures are not useful biomarkers for disease monitoring in Blau syndrome, highlighting the need to identify alternative biomarkers reflecting NOD2-mediated inflammatory pathways.\n\nID: 42253989\nTitle: Epstein-Barr virus-associated multiple sclerosis: recent mechanistic advances and clinical therapeutic perspectives.\nAbstract: Multiple sclerosis (MS) is an immune-mediated chronic inflammatory and degenerative disease of the central nervous system (CNS). Typically occurring in young and middle-aged individuals, untreated MS can have high rates of disability and recurrence, thereby imposing a significant burden on the patient, their family, and society. Many factors are implicated in the etiology of MS, with the relationship between Epstein-Barr Virus (EBV) infection and the development of MS being the subject of extensive research recently. When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS. Currently, the phenomenon of cross-reactivity resulting from molecular mimicry following EBV infection (including reactivation status) is theorized as a contributing etiology. EBV-mediated abnormalities in T cells and B cells also play a key role in the development of MS. However, the underlying mechanisms have not been thoroughly understood. Meanwhile, the limited availability of effective treatment options for MS, in particular MS progression, underscores the urgent need for novel therapeutic strategies. Here, we discuss the pathophysiological mechanisms underlying MS, specifically emphasizing the relationship between EBV infection and the disease pathology. Furthermore, we introduced relevant pharmacological targets in order to propose a broader range of therapeutic alternatives for individuals diagnosed with MS.\n\nID: 42250005\nTitle: Sexual Dimorphism in Spinal Cord Injury: From Molecular Mechanisms to Clinical Translation.\nAbstract: Traumatic spinal cord injury (SCI) shows pronounced biological sex differences in incidence and short-term outcomes, yet mechanistic studies and therapeutic development are not consistently sex-informed. Here we summarize evidence that sex hormones, sex-chromosome effects and immune-glial interactions shape key components of the secondary injury cascade, including blood-spinal cord barrier (BSCB) disruption, neuroinflammation, oxidative stress, cell death and remyelination. Estrogens and progesterone generally support barrier stabilization, temper leukocyte infiltration, bias microglia/macrophages toward reparative programs, and promote neurotrophin signaling and myelin repair. In males, post-injury androgen deficiency together with stronger early innate immune activation may exacerbate oxidative damage, demyelination and scar formation, potentially limiting plasticity. Clinical evidence remains limited and confounded, but available data support the need for adequately powered, sex-stratified trials, particularly for time-sensitive hormonal and immunomodulatory interventions. Incorporating sex as a biological variable in experimental design and translation may improve target selection, dosing and therapeutic windows for SCI.\n\nID: 42193931\nTitle: Memory Impairments: Type, Causes, and Molecular Players-Memory Dysfunction Across Neurologic Insults.\nAbstract: Viral infections of the central nervous system produce memory impairment through mechanisms that extend beyond acute neuronal injury. Herpes simplex virus type 1, human immunodeficiency virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, influenza, SARS-CoV-2, West Nile virus, and Zika virus each enter or engage the brain through distinct routes, yet converge on four shared molecular pathways that selectively damage hippocampal circuits: mitochondria-associated membrane (MAM) dysfunction, chronic neuroinflammation, blood-brain barrier (BBB) disruption, and impaired CREB-BDNF signaling. These pathways specifically compromise the dentate gyrus, CA3, and CA1 subfields, producing predictable deficits in pattern separation, associative retrieval, and temporal memory binding. Antiretroviral and antiviral therapies suppress viral replication but fail to reverse organelle-level dysfunction, leaving most hippocampal injury unaddressed. Emerging plasma biomarkers, p-tau217, neurofilament light chain, and GFAP, combined with hippocampal subfield MRI, now enable mechanistic stratification before irreversible circuit loss occurs. This review proposes, as a unifying hypothesis, that virus-associated memory impairment represents a convergent hippocampal syndrome driven by shared downstream pathways, and that combination therapies targeting these pathways simultaneously offer greater therapeutic promise than pathogen-specific approaches alone. The evidentiary basis for this framework varies across pathogens and conditions; direct mechanistic evidence, mechanistic analogy, and preclinical data are distinguished throughout.\n\nID: 42177552\nTitle: Microbiota-derived butyrate inhibits colonic epithelial pyroptosis and mitigates DSS-induced colitis via interacting with aryl hydrocarbon receptor.\nAbstract: Intestinal barrier defects cause antigen translocation and immune dysregulation. The pyroptosis of colonic epithelial cells (CECs) disrupts the colonic barrier, and its inhibition might be a therapeutic approach for ulcerative colitis (UC), but the mechanisms are not fully understood. A DSS-induced UC model was established to assess the level of colonic epithelial cell pyroptosis. 16S rDNA sequencing and LC\u2012MS/MS were applied to screen potential candidate bacterial species and metabolites. The roles of target metabolites were evaluated in vivo using GSDMD-knockout mice. FHC cells treated with LPS\u2009+\u2009ATP were used as a cellular model of pyroptosis, and the underlying molecular mechanism was explored mainly by siRNA transfection and lentivirus infection. We found that DSS-treated mice exhibited increased levels of pyroptosis in the colon. Fecal microbiota transplantation (FMT) significantly suppressed mucosal inflammation and CEC pyroptosis, accompanied by increased levels of butyrate-producing bacteria and butyrate in feces. Butyrate treatment alleviated DSS-induced colitis in mice. Moreover, GSDMD knockout mitigated DSS-induced colitis in mice, whereas a butyrate intervention failed to further ameliorate colitis in GSDMD-knockout mice. Mechanistically, we found that butyrate significantly inhibited LPS\u2009+\u2009ATP-induced pyroptosis by activating its receptor, aryl hydrocarbon receptor (AhR), in FHC cells, while silencing AhR suppressed this effect. The overexpression of cGAS in FHC increased the level of pyroptosis, whereas the administration of butyrate inhibited the activation of the cGAS-STING pathway. Treatment with a cGAS inhibitor significantly reversed the increase in pyroptosis caused by AhR knockdown in pyroptotic FHC cells. Gut microbiota-derived butyrate levels were increased after FMT. Butyrate suppressed the proinflammatory cGAS-STING-NF-\u03baB signaling axis via AhR to inhibit CEC pyroptosis and thereby alleviate UC.\n\nID: 42140444\nTitle: ISG15/ISGylation in central nervous system diseases: molecular mechanisms and therapeutic targeting.\nAbstract: Interferon-stimulated gene 15 (ISG15) is a ubiquitin-like modifier that plays a central role in innate immune signaling and antiviral defense. Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks. In this review, we summarize current insights into the molecular and cellular roles of ISG15 in neuroinflammation, highlight its dual protective and pathogenic functions, and discuss therapeutic strategies and future directions for targeting ISG15-related pathways in CNS diseases.\n\nID: 42125999\nTitle: Molecular Mimicry Between Epstein-Barr Virus and Human Herpesvirus-6 Proteins and Central Nervous System Proteins: Implications for T and B Cell Immunogenicity in an In Silico Study.\nAbstract: The Epstein-Barr virus (EBV) and human herpesvirus 6 (HHV-6) are frequently linked to neuropsychiatric illnesses such as multiple sclerosis, depression, and chronic fatigue syndrome/myalgic encephalomyelitis. These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self-epitopes in the central nervous system (CNS). This study seeks to explore the common pentapeptides present in EBV and HHV-6 viral antigens alongside various CNS-related proteins via molecular mimicry. Additionally, it will assess the immunogenicity of these shared pentapeptides in T and B cells. Sequence alignment was conducted to assess molecular mimicry between 32 EBV and HHV-6 antigens and 10 CNS autoantigens. Protein sequences were obtained from UniProt, structural homology was analyzed using AlphaFold and PyMol, and shared pentapeptides were identified with Alignmentaj. Immunogenicity was assessed via the Immune Epitope Database (IEDB) for potential T- and B-cell activation. A total of 91 mimicry pentapeptides were identified between viral antigens (42 EBV and 49 human HHV-6), and 10 CNS proteins. Notably, synapsin (SYN)1 exhibited the highest mimicry, sharing 13 pentapeptides with (7 with EBV and 6 with HHV-6) viral antigens such as EBV nuclear antigen (EBNA)1, EBNA6, latent membrane protein (LMP)1, and early antigen diffused (EA-D). Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens. EBNA1, EBNA2, EBNA6, LMP1, LMP2, EA-D, and BLLF1 structurally resemble CNS autoantigens and act as immunoreactive epitopes for human T and B cells. Except for EBNA2 and protein U94, all share immunogenic pentapeptide sequences with SYN1. Shared pentapeptides suggest a link between viral infections and CNS autoimmunity. Further research is needed to clarify molecular mechanisms and explore targeted therapies to mitigate virus-induced neuroinflammation.\n\nID: 42118409\nTitle: iPSC-Derived 3D Brain Organoids as Next-generation Platforms to Study Viral and Toxicant-associated Neurodegeneration.\nAbstract: Neurodegenerative diseases (ND) are one of the most fatal diseases that affect the majority of individuals worldwide, among which Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common. In vitro 2D monolayer cell cultures and in vivo transgenic animal models have been the primary tools for investigating mechanisms of neurodegenerative diseases. However, the ineffectiveness of these models in translating outcomes into human pathophysiology, necessitates innovative approaches to bridge the translational gap. In this review, we focus on the intricate pathogenic processes by which environmental toxicants and viral infections trigger neurodegeneration. The growing significance of three-dimensional (3D) brain organoids (BOs) derived from induced pluripotent stem cells (iPSCs) can be used as a groundbreaking platform for examining neurodegenerative pathways induced by exposure to environmental toxicants and viral infections. It also addressed how BO's overcomes the fundamental limitations of traditional models, such as 2D cultures and animal models, thereby creating novel opportunities for the mechanistic study of multifactorial neurodegeneration and the development of therapeutic interventions.\n\nID: 42041941\nTitle: Triple Latency as a Driver of Chronic Inflammation: An Integrative View of HSV, EBV, and CMV Persistence in Immunocompetent Hosts.\nAbstract: Background: Herpes simplex virus (HSV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) establish lifelong latency in sensory neurons, lymphoid tissue, and myeloid-endothelial cells, respectively. A substantial proportion of adults worldwide are infected with all three viruses and may experience concurrent herpesvirus latency, yet they have largely been studied independently. This review examined whether latent and intermittently reactivating herpesviruses share overlapping inflammatory signatures and whether their combined presence contributes to chronic inflammatory burden. Methods: A narrative integrative review was conducted using MEDLINE, Embase, and Google Scholar (inception-October 2025). Evidence from thirty-one cohort studies and mechanistic investigations spanning virology, immunology, neurology, and clinical medicine was synthesized. Results: Herpesvirus reactivation rates ranged from 23% in general Intensive Care Unit (ICU) populations to 85% in severe COVID-19. Concurrent reactivation of multiple viruses occurred in 34-63% of critically ill patients and was associated with worse clinical outcomes. Notably, simultaneous CMV and EBV reactivation independently predicted mortality (adjusted hazard ratio, 3.17; 95% CI, 1.41-7.13). Across infections, overlapping inflammatory biomarkers, including IL-6, TNF-\u03b1, CRP, and PGE2, were consistently elevated, reflecting convergent activation of IFN and NF-\u03baB signaling pathways. Mechanistic studies suggest cross-compartment immune priming, where CMV-driven T-cell exhaustion facilitates EBV reactivation, and viral cytokine signaling enhances HSV-associated neuroinflammation. Conclusions: HSV, EBV, and CMV triple latency may represent an underrecognized contributor to chronic inflammation in immunocompetent hosts. Understanding this multi-virus inflammatory network may inform mechanistic research, biomarker-guided risk stratification, and therapeutic strategies targeting convergent inflammatory pathways. Prospective interventional studies incorporating concurrent multi-virus monitoring are needed to clarify causal relationships.\n\nID: 42030364\nTitle: Duck plague virus LORF2 utilizes RNF34 to inhibit antiviral innate immunity by ubiquitination and degradation of IRF7.\nAbstract: Duck plague, caused by the alphaherpesvirus Duck plague virus (DPV), is an acute, hemorrhagic, and economically devastating disease of waterfowl. DPV infection induces severe immunosuppression, yet the mechanisms by which this pathogen subverts host innate immunity, particularly through manipulation of the host ubiquitin system, remain unclear. The cGAS-STING signaling pathway is a cornerstone of anti-DNA viral immunity. In avian species, where IRF3 has been evolutionarily lost, the transcription factor IRF7 plays a pivotal role in activating type I interferons (IFN-I). Here, we identify duck RNF34 (DuRNF34) as a host E3 ubiquitin ligase that broadly suppresses the duck cGAS-STING pathway by targeting multiple components, including DucGAS, DuSTING, and DuIRF7, for ubiquitination and degradation. Importantly, DPV infection upregulates DuRNF34 expression, which selectively targets DuIRF7 for degradation to facilitate viral replication. Further affinity purification-mass spectrometry (AP-MS) analysis revealed that LORF2, a DPV-specific protein, recruits DuRNF34 to catalyze K11- and K48-linked polyubiquitination of DuIRF7 at lysine residues K51 and K453, leading to DuIRF7 degradation and suppression of IFN-\u03b2 and downstream antiviral genes. Functional validation confirmed that siRNA-mediated knockdown of LORF2 markedly attenuated DPV-induced DuIRF7 degradation and impaired viral replication. Collectively, these findings reveal a novel immune evasion strategy in which DPV hijacks the host E3 ligase DuRNF34 via its unique protein LORF2, thereby targeting DuIRF7 for degradation to subvert innate immunity. This work provides new insights into herpesviral immune evasion and suggests potential targets for therapeutic intervention.\n\nID: 42025559\nTitle: The role of Epstein-Barr virus in multiple sclerosis: From pathogenesis to therapeutic potential.\nAbstract: A growing body of evidence positions Epstein-Barr virus (EBV) as a central agent in the etiopathogenesis of multiple sclerosis (MS). Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development. This is supported by pathology findings revealing EBV-infected B cells within CNS lesions and immunogenetic data linking viral and human genetic susceptibility to MS risk. Mechanistically, EBV appears to act as an upstream trigger that reshapes B cell function, promotes molecular mimicry with CNS antigens, and drives compartmentalized neuroinflammation. In this Review, we synthesize epidemiological, pathological, immunogenetic, and clinical-therapeutic evidence to construct a coherent model of EBV-driven MS pathogenesis. We examine how current MS therapies intersect with EBV biology and discuss the challenges and opportunities in developing EBV-targeted strategies, including vaccines and antivirals, for disease prevention and early intervention. Finally, we highlight key unresolved questions and outline a translational research agenda aimed at intercepting MS through virologically informed approaches.\n\nID: 42025008\nTitle: Hongqi Shenmai Yin attenuates adverse cardiac remodeling following myocardial infarction via inhibition of STING-dependent PANoptosis.\nAbstract: Pathological ventricular remodeling following myocardial infarction (MI) severely impacts long term prognosis of patients, yet effective interventions to halt its progression remain limited. Hongqi Shenmai Yin (HSY) has been used in clinical practice for many years, can improve cardiac function in MI patients. However, its underlying therapeutic mechanisms remain unclear. This study aimed to determine whether HSY alleviates adverse cardiac remodeling following MI by inhibiting stimulator of interferon genes (STING)-dependent PANoptosis. The MI model was established by ligating the left anterior descending coronary artery (LAD) in rats. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS) identified bioactive compounds in HSY. Cardiac function, hypertrophy, and fibrosis were assessed via echocardiography and histological staining. ELISA measured cardiac injury biomarkers, inflammatory cytokines, and oxidative stress markers. Transcriptomic analyses identified potential HSY targets in post-MI remodeling. Molecular docking and surface plasmon resonance (SPR) assessed binding interactions between HSY's key active components and STING. Mechanistic rescue experiments determined whether HSY regulates PANoptosis via STING inhibition. Functional studies were further conducted by transfecting H9c2 cardiomyocytes with lentivirus vectors encoding STING-overexpression. HSY attenuated inflammation, oxidative stress, and adverse remodeling while improving cardiac function post-MI. UPLC-MS identified 107 major HSY constituents. Transcriptomics linked HSY's cardioprotective effects to STING signaling and PANoptosis modulation. Molecular docking and SPR confirmed strong binding affinity between HSY's primary active compounds and STING. Both in vivo and in vitro experiments revealed that HSY suppressed STING-induced ZBP1-PANoptosome assembly, downregulating PANoptosis-associated proteins (p-MLKL, p-RIPK1, p-RIPK3, GSDMD-NT, GSDME-NT, Cle-CASP1, Cle-CASP3, Cle-CASP8) in post-MI remodeling. HSY attenuated adverse cardiac remodeling following MI by inhibiting STING-mediated ZBP1-PANoptosome assembly and subsequent PANoptosis. These findings supported HSY's clinical potential in treating post-MI cardiac remodeling.\n\nID: 42014318\nTitle: New immunotherapies for multiple sclerosis (MS): A comprehensive review.\nAbstract: Multiple sclerosis (MS) is the leading cause of non-traumatic disability in young adults, characterized by autoimmune demyelination and neurodegeneration. While high-efficacy therapies have transformed relapsing MS management, disability progression remains an unmet need. Emerging evidence implicates compartmentalized central nervous system (CNS) inflammation, including microglial activation, in disease pathogenesis, necessitating novel immunotherapeutic strategies that target both peripheral and CNS-resident immune cells. This review synthesizes recent preclinical and clinical data on emerging MS immunotherapies offering promise for halting disability progression in MS. Their clinical integration will depend on balancing efficacy with safety, particularly in progressive phenotypes where therapeutic options remain limited.\n\nID: 41993619\nTitle: Attenuation of cGAS-STING signaling-mediated lung inflammation during infection through autophagy induction by bioactive nanodevices.\nAbstract: Modulating the cGAS-STING pathway by bioactive nanodevices is a promising strategy for combating infection-associated inflammatory disorders. However, the development of pharmacological inhibitors for cGAS-STING signaling is currently hindered by lacking cell-specific targeting capability. This study aimed to develop a potent, drug-free nanodevice that specifically targets pulmonary macrophages to modulate the cGAS-STING pathway for ameliorating infection-associated detrimental lung inflammation. Cigarette smoke extract-modified peptide gold nanoparticle hybrids (CSE-P12) were synthesized. Transcriptomic analysis, western blotting, autophagy reporter assays, and confocal microscopy were employed to assess the effects of CSE-P12 on gene expression, STING degradation, autophagic flux, and inflammation. TEM imaging and LC-MS/MS were utilized to elucidate the molecular mechanisms underlying CSE-P12-induced autophagy in macrophages. Finally, the HAdV4-induced pneumonia and CLP-induced sepsis models on wild-type and STING-/- mice were used to evaluate the therapeutic efficacy of CSE-P12 and validate its inhibitory mechanisms on the cGAS-STING pathway. CSE-P12 nanodevices are extensively internalized by macrophages via energy-dependent cellular uptake. This large internalization triggers autophagic degradation of STING, thereby effectively inhibiting the cGAS-STING-mediated interferon responses and inflammation. In the HAdV4-induced viral pneumonia mouse model, intratracheally instilled CSE-P12 effectively targets pulmonary macrophages, suppresses STING activation, and significantly alleviates lung inflammation and injury. The depletion of the pulmonary macrophages abolishes these protective effects. The therapeutic potential of CSE-P12 is further validated in a CLP-induced polymicrobial sepsis mouse model, where it significantly prolongs mouse survival and decreases lung inflammation. CSE-P12 effectively targets pulmonary macrophages and exhibits potent anti-inflammatory activities in viral pneumonia and sepsis-induced acute lung injury by inducing autophagic flux to facilitate STING degradation. This work provides a new paradigm for designing targeted nanotherapeutics to modulate STING activation in inflammatory diseases.\n\nID: 41991590\nTitle: SLC30A10 downregulation is associated with cGAS-STING pathway activation in colorectal tubular adenoma.\nAbstract: Based on data-independent acquisition (DIA) proteomics technology, to analyze the proteomic characteristics of colorectal tubular adenoma and explore the expression changes of SLC30A10 and their potential association with the cGAS-STING pathway. A self-controlled design was adopted, collecting colorectal tubular adenoma (TA) and paired normal mucosa (NM) from 15 patients with TA. Differentially expressed proteins were screened by DIA proteomics, followed by GO and KEGG enrichment analyses. Immunohistochemistry was performed to detect the expression of SLC30A10, cGAS, STING, p-IRF3, ISG15, and \u03b2-catenin; immunofluorescence double staining was used to observe the co-localization of p-IRF3 and \u03b2-catenin; inductively coupled plasma mass spectrometry (ICP-MS) was employed to determine tissue manganese content. DIA analysis showed that SLC30A10 protein expression was significantly downregulated in TA tissues. Functional enrichment analysis indicated abnormalities in signal transduction, metabolic reprogramming, and nitrogen metabolism in TA tissues. IHC results demonstrated that, compared with NM, TA tissues exhibited reduced expression of SLC30A10, while the expression of cGAS, STING, p-IRF3, ISG15, and \u03b2-catenin was upregulated. Manganese content in TA tissues was also significantly increased. Immunofluorescence revealed enhanced nuclear signals of p-IRF3 in TA cells, with co-localization of p-IRF3 and \u03b2-catenin observed in the nucleus. Downregulation of SLC30A10 in colorectal tubular adenoma is associated with manganese accumulation and alterations in the cGAS-STING pathway, suggesting its potential role in the development and progression of adenoma, a finding with promising research implications.\n\nID: 41981407\nTitle: Extensive peripheral immunoglobulin repertoire analyses in people with multiple sclerosis reveal disease-specific signatures and distinct treatment effects of disease modifying drugs.\nAbstract: BACKGROUND: B cells are crucial players in the pathogenesis of multiple sclerosis (MS), however, limited information is available on peripheral immunoglobulin (Ig) repertoires of people with MS (pwMS) in comparison to healthy individuals and during different treatments. METHODS: Next generation sequencing of Ig heavy chains (VH) originating from bulk-sorted B cell populations was performed in 33 pwMS and ten healthy controls. All 33 pwMS were examined longitudinally at baseline and six months after treatment with ozanimod, fingolimod, dimethyl fumarate, teriflunomide, cladribine or natalizumab. Ig peptides were obtained longitudinally in a subset of treated pwMS by Ig mass spectrometry, overlapped with VH transcriptomes through nf-core bioinformatics workflow analysis and additionally Ig serum level and anti-Epstein-Barr virus IgG level (EBNA1) were measured. RESULTS: VH repertoires of treatment-na\u00efve pwMS showed a significantly decreased diversity in the double negative B cells and different usage of IGHV genes when compared with healthy controls. Quantitative changes in B cell subsets during treatment were accompanied by qualitative changes in Ig repertoires with a significantly decreased diversity in the naive, memory B cells and plasmablasts during ozanimod treatment. A similar trend was noticeable for all other treatments except natalizumab. No qualitative change in Ig peptides overlapping with Ig transcriptome repertoires was observed. CONCLUSIONS: This study provides first evidence for an altered peripheral Ig repertoire in pwMS. In addition, various treatments seem to shift the composition of B cells towards an increased fraction and activation of the naive B cell pool and a reduced fraction of memory B cells with reduced clonal diversity.\n\nID: 41979342\nTitle: UPLC-Q-TOF/MS-Based Metabolomics and 16S rRNA Profiling Reveal that Corosolic Acid Ameliorates High-Fat Diet-Induced MASLD by Modulating the Gut-Liver Axis to Inhibit the cGAS-STING Pathway.\nAbstract: Metabolic-associated steatohepatitis liver disease (MASLD) is characterized by abnormal hepatic fat accumulation and liver injury. Corosolic acid (CA) has proven lipid-lowering and hepatoprotective effects, yet the underlying mechanism by which CA mitigates MASLD remains unclear. In this study, mice were fed a high-fat diet for 8 weeks to induce MASLD, followed by 8 weeks of CA intervention. We found that CA significantly suppressed weight gain, reduced serum lipid levels, and improved liver function in the HFD-fed mice. Fecal metabolomic analysis showed that CA regulated multiple metabolic pathways including histidine metabolism and altered 10 shared metabolites between feces and serum, such as HAD-Car. 16S rRNA sequencing and fecal microbiota transplantation confirmed that CA reshaped gut microbiota, upregulating beneficial bacteria (e.g., Lachnospiraceae_NK4A136_group) and downregulating harmful strains (e.g., Blautia ). Mechanistically, HAD-Car alleviated MASLD by inhibiting the cGAS-STING pathway. Collectively, CA exerts anti-MASLD effects via regulating gut microbiota and metabolites, offering new insights into MASLD treatment.\n\nID: 41949651\nTitle: An autoantibody signature predictive for multiple sclerosis: evidence at the protein level and association with histopathological lesion types.\nAbstract: Recently, an autoantibody signature considered to be predictive of multiple sclerosis (MS) has been reported in an article by Zamecnik et al. published in Nature Medicine, which is characterized by immunoglobulin G (IgG) responses to peptides sharing the amino acid motif P-(SA)-x-(SGA)-R-(SN)-(LRKH). These results are highly important, all the more so as the same motif is present also in two proteins expressed by Epstein-Barr virus (EBV), a pathogen that likely plays a key role in MS pathogenesis. However, clinically relevant autoantibody responses often target conformational epitopes, and peptides often differ from their corresponding proteins in terms of conformation. We were therefore interested in whether these findings can be reproduced at protein level and may thus play a role also in vivo. Here, we report findings from complementary experiments employing a microarray covering nearly 10,000 human full-length proteins and using serum and cerebrospinal fluid samples from patients with a histopathologically confirmed diagnosis of MS. Our data show that prominent IgG responses to full-length proteins bearing the P-(SA)-x-(SGA)-R-(SN)-(LRKH) motif can indeed be found in a substantial proportion of MS patients, although considerable inter-patient variability exists in both the type and number of individual responses. Notably, these IgG responses were more pronounced in patients with histopathologically defined pattern II MS (which is characterized by intralesional IgG and complement deposition) and pattern III MS than in patients with pattern I MS in our study. New motif-bearing candidate antigens identified in this study include RBMY2FP, CHMP2B, SRSF8 (SFRS2B), NUS1 (NgBR, Nogo-B receptor), and RTN2. Further studies investigating the diagnostic, pathophysiological, therapeutic, and prognostic implications of this antibody signature, as well as the potential role of cross-reactivity with EBV-suggested by the presence of the motif of interest in both EBV BRRF2 and EBV envelope glycoprotein M-are warranted and may significantly advance our understanding of MS.\n\nID: 42406535\nTitle: Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway.\nAbstract: Pyroptosis is an inflammatory type of programmed cell death that may contribute to epilepsy initiation and progression through neuroinflammation. Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n\nID: 42404903\nTitle: Cholinergic regulation of neuroinflammation: linking microglia, immunometabolism, and neuromodulation.\nAbstract: Neuroinflammation is increasingly recognized as a core pathological process in various neurological diseases, including neurodegenerative disorders, stroke, autoimmune demyelinating diseases, and acute brain dysfunction associated with systemic inflammation. Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention.\n\nID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\n\nID: 42401266\nTitle: Naja atra SVPLA2 upregulates hexokinase 2-driven macrophage M1 polarization via the cGAS-STING signaling activation.\nAbstract: Snake venom phospholipase A2 (SVPLA2) from Naja atra (N. atra) drives macrophage M1 polarization through hexokinase 2 (HK2)-mediated glycolytic reprogramming; however, the upstream mechanism by which SVPLA2 upregulated HK2 remains unclear. The cGAS-STING pathway has been widely shown to regulate HK2 expression in macrophages, but whether it participated in SVPLA2-induced HK2 upregulation was unknown. Herein, we found that in RAW 264.7 macrophages, N. atra SVPLA2 triggered mitochondrial dysfunction and mtDNA release. Subsequently, SVPLA2 activated the cGAS-STING pathway. Gene silencing of STING using siRNA abrogated SVPLA2-induced HK2 upregulation and suppressed M1 polarization. Taken together, this study revealed the cGAS-STING-HK2 axis as an important upstream mechanism underlying N. atra SVPLA2-induced metabolic reprogramming of macrophages, providing new insights into the pathogenic mechanisms of snake venom.\n\nID: 42401006\nTitle: Spinal cord microglia exhibit a dysfunctional response to myelin damage.\nAbstract: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that affects both the brain and spinal cord, although the brain has historically received greater attention. In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair.\n\nID: 42400090\nTitle: Study protocol: double-blind, randomized, prospective, placebo controlled parallel group phase II study to investigate the effect of glycerol phenylbutyrate (GPB) on neurofilament light chain (NfL) levels in patients with corticobasal syndrome (CBS).\nAbstract: Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disorder, with no disease-modifying treatments currently available. The most common underlying pathology is a 4-repeat tauopathy. Neurofilament light chain (NfL) is a biomarker of neuronal damage and has shown potential as a measure of disease progression. Glycerol phenylbutyrate (GPB), a prodrug of phenylbutyric acid, has demonstrated potential neuroprotective properties in preclinical studies on tauopathies. This phase II clinical trial will investigate the effects of GPB on NfL levels in CBS patients. The primary objective is to assess the efficacy of GPB in reducing NfL levels over 26\u00a0weeks compared to placebo as well as safety and tolerability of GPB. Secondary objectives include evaluating changes in clinical scales. This is an investigator-initiated double-blind, randomized, placebo-controlled, parallel-group phase II clinical trial, performed in two German university hospitals. A total of 32 patients with CBS will be enrolled and randomized to receive either GPB or placebo. The primary outcome is the change in NfL levels between baseline and 26\u00a0weeks as well as safety and tolerability of GPB. Secondary outcomes are changes in clinical scores. Exploratory analyses involve pharmacokinetics, changes in the metabolomic, proteomic and lipidomic profiles and imaging outcomes, such as MRI and microglia-PET. The study protocol has been approved by the lead ethics committee at LMU Munich and conforms to the ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines. If successful, this clinical trial could identify a novel therapeutic approach for slowing disease progression in CBS, contributing to a broader understanding of GPB's therapeutic potential. The clinical trial has been registered in ClinicalTrials.gov (NCT05983588) and due to Transition in the Clinical Trials Information System (CTIS; EUCT No. 2024-516897-31-00, date of transition: 2024-09-26).\n\nID: 42399983\nTitle: Regional mapping of CSF1R-positive microglia in neurodegenerative diseases and progressive MS, with exploratory presynaptic marker analyses.\nAbstract: Microglial colony-stimulating factor-1 receptor (CSF1R) is a therapeutic and imaging target, yet the regional, disease-specific distribution of CSF1R-positive microglia in the human brain remains incompletely defined, limiting interpretation of emerging CSF1R-PET signals. We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers. A cross\u2011disease, region\u2011resolved map reveals region\u2011specific changes in CSF1R\u2009+\u2009cell density in neurodegeneration, but only white matter in MS. These findings provide the histological context needed to interpret future CSF1R\u2011PET. Prospective studies pairing CSF1R\u2011PET with SV2A\u2011PET and multiplex tissue profiling are warranted to define microglial states and synaptic outcomes in vivo.\n\nID: 42397737\nTitle: STING-dependent peripheral inflammaging drives neurodegeneration via extracellular vesicles.\nAbstract: All animals age. However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration.\n\nID: 42397694\nTitle: Border-Associated Macrophages in CNS Health and Disease: A Comprehensive Review of Ontogeny, Heterogeneity, and Functional Plasticity at Neural Interfaces.\nAbstract: Border-associated macrophages (BAMs) represent a specialized population of tissue-resident immune cells strategically positioned at the critical interfaces between the central nervous system (CNS) and peripheral circulation, including the meninges, choroid plexus, and perivascular spaces. As frontline sentinels of the neuroimmune system, BAMs perform essential functions in immune surveillance, barrier integrity maintenance, and homeostatic regulation, yet their unique biology and disease-associated roles remain incompletely characterized compared to parenchymal microglia. This review aims to synthesize current knowledge on BAM ontogenetic origins, compartment-specific heterogeneity, transcriptional programs, and functional outputs in both health and neurological disorders. We conducted a comprehensive literature analysis integrating findings from lineage tracing studies, single-cell RNA sequencing, spatial transcriptomics, and functional interrogation in animal models of disease. The results reveal that BAMs exhibit remarkable cellular diversity shaped by distinct ontogenetic origins-primarily yolk sac-derived erythro-myeloid progenitors with variable contributions from fetal liver and postnatal monocytes depending on anatomical compartment. Compartment-specific marker combinations (CD206, LYVE1, CD163, MHCII) define functionally distinct subsets, and core transcriptional regulators including PU.1 and IRF8 maintain BAM identity while CSF-1/IL-34-CSF1R signaling governs survival and renewal. In neurological disorders including ischemic stroke, Alzheimer's disease, multiple sclerosis, and brain tumors, BAMs display pronounced double-edged roles, transitioning from protective homeostatic guardians to pathogenic drivers depending on disease stage and microenvironmental context. This comprehensive analysis establishes a unified framework for understanding BAM biology and identifies critical opportunities for developing subset-specific therapeutic strategies targeting these interface macrophages in neurological diseases.\n\nID: 42395420\nTitle: Replication-deficient Adenovirus 5 Serotypes Induce Type I Interferon and enhance BCG-mediated Immune Response in Co-infected Murine Macrophages.\nAbstract: Tuberculosis (TB) remains a leading global cause of infectious mortality due, in part, to the limited efficacy of the Mycobacterium bovis BCG vaccine against pulmonary TB. Previous studies in mice have shown that stimulating type I interferon (IFN) signaling during BCG vaccination can bolster protection against Mycobacterium tuberculosis , yet clinically feasible delivery strategies for this approach are lacking. Adenoviral vectors, which induce potent type I IFN responses and are utilized in approved vaccine platforms, represent a promising adjuvant strategy. To evaluate the host immune response to this combination, bone marrow-derived murine macrophages were co-infected with replication-deficient adenovirus and BCG. Adenovirus-infected macrophages elicited a robust type I IFN response via the cGAS/STING pathway. Compared to BCG infection alone, co-infected macrophages exhibited additive expression of genes with known host-protective roles against M. tuberculosis . Conversely, co-infection with BCG suppressed adenovirus-induced type I IFN signaling and diminished the production of IFN-stimulated genes compared to adenovirus infection alone. Together, these findings reveal a complex regulatory interplay during adenovirus and BCG co-infection. While BCG partially restricts adenoviral IFN induction, the co-infection still drives an enhanced host-protective gene profile, suggesting that adenoviral vectors could serve as a viable platform to modulate innate immunity and improve BCG vaccine efficacy. Tuberculosis (TB) remains the leading cause of death by a single infectious organism with approximately 1.25 million deaths annually. M. bovis BCG remains the only approved vaccine for TB; however, its efficacy against the contagious and most common pulmonary form of the disease is limited. There have been numerous attempts to improve BCG efficacy, but these approaches have not resulted in any clinically approved vaccine. We propose that BCG combined with a replication-deficient adenovirus presents a way to bolster vaccine-conferred protection as the combination may elicit a robust innate immune response and drive a more protective T cell response. Moreover, BCG and replication-deficient adenoviruses have well-assessed safety profiles and decades of studies regarding their use in patients. The significance of our work is in leveraging their complementary immunology to function as a combined vaccine platform. This approach presents a novel and clinically feasible approach to improve the BCG vaccine.\n\nID: 42394904\nTitle: Engineering the tumor immune landscape: Translating non-invasive physical stimulation into tumor-associated macrophage-targeted cancer immunotherapy.\nAbstract: Tumor-associated macrophages (TAMs) shape the tumor microenvironment through plastic transitions between pro-inflammatory M1-like and immunosuppressive M2-like states, yet clinical drug therapies are limited by toxicity, resistance, and delivery barriers. This review explains how non-invasive physical stimulation (NIPS) reprograms TAMs via defined couplings between physical inputs and signaling pathways. Hypoxia-tolerant photodynamic strategies and mild photothermal heating reset hypoxia- and lactate-driven programs; cavitation-dominant ultrasound and sonodynamic therapy trigger danger signaling and reactive oxygen species; ultrasound microbubble destruction provides endothelial repair cues; nanosecond pulsed electric fields activate cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway; piezoelectric materials convert mechanical input into calcium-dependent transcription; and appropriately dosed radiotherapy elicits immune-active responses while avoiding hypoxia-driven M2 recruitment. Across models, these regimens promote pro-inflammatory reprogramming, normalize aberrant vasculature, and strengthen antitumor immunity while restraining immunosuppression. We synthesize parameter windows, delivery options, and combination strategies with checkpoint blockade and macrophage-directed agents to guide the translation of NIPS into precise, low-toxicity TAM-targeted immunotherapy.\n\nID: 42394822\nTitle: STING agonist 2'3'-cGAMP as an effective adjuvant for HPV16 peptide vaccine enhances anti-tumor immunity in TC-1 mice models.\nAbstract: Adjuvants are critical for enhancing vaccine immunogenicity. The agonists in cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway have demonstrated robust immune activation in preclinical models. Peptide vaccines targeting T cell epitopes of high-risk human papillomavirus (HPV) E6 and E7 represent a promising immunization strategy. To improve immunogenicity, we utilized the STING agonist 2'3'-cGAMP as an adjuvant and evaluated its ability to enhance immune responses and antitumor efficacy. The immunogenicity and efficacy of a candidate vaccine, consisting of the HPV16 E743-77 peptide adjuvanted with 2'3'-cGAMP, were evaluated in established TC-1 tumor transplantation models with different initial tumor sizes (2-3 mm and 5-6 mm in diameter). Tumor-bearing mice received three weekly peritumoral subcutaneous vaccine doses. The effects on tumor suppression, antigen-specific cytotoxic T lymphocyte (CTL) response induction, and related immune mechanisms were investigated both in vitro and in vivo. Immunization with the E743-77 peptide adjuvanted by 2'3'-cGAMP significantly suppressed tumor growth and elicited high levels of Interferon (IFN)-\u03b3 and Granzyme B in CD8+ cytotoxic T lymphocytes. The vaccine also enhanced the differentiation of natural killer (NK) cells, dendritic cells (DCs), and M1-type macrophages, reduced Myeloid-derived suppressor cells (MDSCs), and increased INF-\u03b2 levels, as well as promote lymphocyte infiltration and remodeling in tumor immune microenvironment (TME). Mechanistically, 2'3'-cGAMP promoted DC maturation, enhanced T cell proliferation and activation, and strengthened antigen-specific CTL responses by activating the STING-TBK1-IRF3 and STING-NF-\u03baB pathways in peptide-loaded DCs. The STING agonist 2'3'-cGAMP serves as an effective adjuvant that enhances the therapeutic efficacy of an HPV16 peptide vaccine. These findings indicate its potential as a candidate therapeutic for HPV16 persistent infection and associated malignancies.\n\nID: 42393898\nTitle: Heterocyclic Scaffolds as Therapeutic Agents in Multiple Sclerosis: Mechanisms and SAR Study.\nAbstract: Multiple sclerosis (MS) is a progressive, immune-mediated condition characterized by the destruction of myelin, the protective insulation surrounding nerve fibers. This ongoing assault triggers a cascade of damage, including persistent inflammatory responses, loss of myelinproducing oligodendrocytes, axonal degradation, and cumulative neurological impairment. While motor and sensory difficulties are hallmark features, patients frequently contend with less visible but equally debilitating symptoms such as cognitive dysfunction, profound fatigue, affective disorders, nerve pain, and autonomic instability. These often-overlooked manifestations critically impact well-being and functional capacity. The pathophysiology of MS is increasingly understood as a network of overlapping cellular and molecular dysfunctions. Alongside irregularities in the endocannabinoid signaling network, key contributors include aberrant immune communication, persistently activated microglia, impaired mitochondrial energy production, and dysregulated activity of enzymes like PDE7, MAGL, ROCK, and PADs. These interconnected pathways collectively drive disease initiation and advancement. This analysis synthesizes established information on current FDA-approved treatments for MS and examines promising novel small-molecule compounds aimed at specific disease-relevant targets. A significant focus is placed on medicinal chemistry advancements, particularly the design and optimization of heterocyclic compounds. Scaffolds incorporating quinolines, pyrimidines, indoles, and related nitrogen-containing structures demonstrate considerable potential for conferring immunomodulation, reducing inflammation, and protecting neural tissue. By evaluating structure-activity relationships, binding mechanisms, and strategic drug design, this review offers an integrated perspective to inform the creation of new, targeted therapies for MS.\n\nID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.\n\nID: 42392741\nTitle: [Dihydroartemisinin ameliorates inflammation in experimental autoimmune encephalomyelitis by enhancing AXL signaling in microglia].\nAbstract: This study aimed to investigate the mechanism of dihydroartemisinin(DHA) in ameliorating multiple sclerosis(MS). Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.\n\nID: 42392399\nTitle: Talazoparib engages innate immune activation via PARP trapping-dependent cGAS/STING activation in Ewing Sarcoma.\nAbstract: Ewing sarcoma (EwS) shows a limited clinical response to poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi), despite promising preclinical data. In this study, we compared five PARPi with different PARP-trapping capacities in PDX-derived cell lines and mouse models. Talazoparib, the strongest PARP-trapping agent, showed markedly greater efficacy than olaparib or veliparib. It triggered extensive DNA damage, micronuclei formation, and activation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway, leading to robust type I interferon and pro-inflammatory cytokine release, an effect not seen in osteosarcoma. In vivo, talazoparib also reshaped the tumor microenvironment, increasing macrophage infiltration and reducing tumor growth. In vitro, conditioned media from treated EwS cells promoted M0-like macrophage polarization towards an inflammatory M1-like status. These immunostimulatory effects were initiated by tumor-derived interferons and were absent in talazoparib-resistant and olaparib-treated EwS cells, underscoring the importance of the PARP trapping activity of PARPi rather than catalytic inhibition. Combination of talazoparib with exogenous 2'-3'-cyclic GMP-AMP (cGAMP) does not further increase phagocytosis of EwS cells when co-cultured with macrophages, and no additive effects were observed under the tested conditions. Thus, talazoparib is a potent cytotoxic agent with innate immune activation/macrophage-mediated effects, prompting further clinical evaluation in this tumor type.\n\nID: 42392330\nTitle: SNX8 interacts with THOC7 to negatively regulate IFN 1 response via the TBK1-IRF3 signaling axis in teleost fish.\nAbstract: Teleost sorting nexin 8 (SNX8) negatively regulates antiviral innate immunity, but its precise mechanism remains unclear. Here, using IP and LC-MS/MS analyses, we identified grass carp THOC7 (CiTHOC7) as a candidate protein that interacts with SNX8. THOC7 was significantly up-regulated in all tested tissues following GCRV infection. Moreover, THOC7 suppressed virus-induced IFN 1 signaling, aggravated GCRV-induced developmental abnormalities of zebrafish embryos, and reduced their survival rates. Further investigations demonstrated that SNX8 interacted with THOC7, facilitated its phosphorylation, and promoted the association between THOC7 and TBK1, thereby suppressing TBK1 phosphorylation. Either THOC7 alone or SNX8 collaborated with THOC7 significantly suppressed GCRV-induced irf3, irf7, and ifn 1 gene transcription, IFN 1 promoter and ISRE activation, as well as IRF7 expression and IFN 1 production. Additionally, they attenuated phosphorylation of TBK1 and IRF3, while affecting IRF7 expression but not its phosphorylation. Collectively, these findings indicated that SNX8 cooperates with THOC7 to negatively regulate the IFN 1 response through the TBK1-IRF3 signaling axis, providing novel insights into the regulatory mechanism of antiviral innate immunity in grass carp.\n\nID: 42383352\nTitle: Therapeutic targeting of the cGAS-STING pathway in human disease.\nAbstract: The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is a central regulator of innate immunity that links cytosolic DNA sensing to type I IFN and inflammatory responses. While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch.\n\nID: 42383100\nTitle: T Helper Cells and Cytokine Networks in the Immunopathogenesis of Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder of CNS with demyelination, neurodegeneration and compartmentalized inflammatory disorder. Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta. The review also explores the cytokine network biomarkers, CSF and serum signatures and single-cell immune states, as well as existing and new drugs. These include migration blockade, targeting of S1P-receptors, anti-CD20 therapy, targeting of Th17/GM-CSF and JAK-STAT pathways, low-dose IL-2, approaches of targeting antigens and engineered Tregs. Investigating the areas of stage and compartment-specific CD4+ T-cell circuits can help to advance targeted immunomodulation in progressive MS and neuro-repair.\n\nID: 42382783\nTitle: HLA-DRB1*15:01 drives sex- and age-dependent microglial immune phenotypes and neuroimmune signaling.\nAbstract: The major histocompatibility complex class II (MHC-II) pathway is central to adaptive immunity and immune tolerance, and its age-related dysregulation is increasingly linked to chronic neuroinflammation. The HLA-DRB1*15:01 allele, the strongest genetic risk factor for multiple sclerosis, has been implicated in shaping pathogenic CD4+ T-cell responses and broader neuroimmune vulnerability, yet how this allele modulates age- and sex-dependent neuroimmune processes within the central nervous system (CNS) remains poorly defined. We investigated the impact of HLA-DRB1*15:01 expression using a humanized mouse model (HLA mice) and wild-type (WT) controls. Male and female mice were analyzed at 6, 9, and 15 months of age, with endocrine stratification in females. Behavioral testing, flow cytometry, immunofluorescence, and multiplex cytokine analyses were used to assess cognitive performance, glial immune-associated changes and oxidative stress, astrocyte-microglia IL-3/IL-3R signaling, endothelial activation, selective immune cell accumulation at CNS borders, tissue organization, and hippocampal cytokine profiles. HLA mice developed age- and sex-dependent cognitive impairment, most pronounced in aged females. HLA-DRB1*15:01 expression promoted progressive microglial immune-associated changes, characterized by increased CD14 and CD68 expression, elevated mitochondrial oxidative stress, altered astrocyte phenotypes, and enhanced IL-3/IL-3R signaling. Hippocampal axonal and myelin organization was disrupted in aged HLA mice and was spatially associated with increased microglial presence. HLA mice also exhibited selective immune remodeling, including increased accumulation of CD4+ T cells and NK1.1+CD3+ natural killer T (NKT) cells, particularly in females, accompanied by endothelial activation marked by elevated ICAM-1 and E-selectin expression. Hippocampal cytokine profiling revealed selective sex-biased alterations, without broad induction of classical inflammatory cytokines. Together, these findings demonstrate that HLA-DRB1*15:01 drives a coordinated, age- and sex-dependent neuroinflammatory program linking behavioral dysfunction, glial immune-associated changes and oxidative stress, selective immune cell recruitment, endothelial activation, tissue remodeling, and targeted cytokine imbalance. This integrated phenotype provides mechanistic insight into how this major MS risk allele confers vulnerability to chronic neuroinflammation during aging, with heightened impact in females, independent of reproductive cycling stage.\n\nID: 42378533\nTitle: Advances in the Study of NOD-Like Receptors in Common Otological Diseases.\nAbstract: Nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) are integral components of the cytoplasmic pattern recognition receptors (PRRs) family, playing a crucial role in both innate immunity and inflammatory responses. Nucleotide-binding oligomerization domain-like receptors detect pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), activating multiple signaling pathways, including nuclear factor-\u03baB (NF-\u03baB) and mitogen-activated protein kinase (MAPK), and triggering immune responses through inflammasome activation. The NLR family contains 5 distinguishable subfamily classifications. The development and progression of multiple ear-related disorders depend significantly on NOD1, NOD2, NLRP3, and NLRX1, among other specific members of the NLR family. The analysis investigates NLRs' interactions with ear pathologies, particularly focusing on NLRP3 functions in the development of otitis media along with its effect on cholesteatoma formation and hearing loss. In addition, this review evaluates targeted therapeutic strategies derived from NLRs research by developing a theoretical foundation that suggests new ways for advancing treatments for otological diseases.\n\nID: 42377966\nTitle: Blood cytotoxic natural killer-like CD8 + CD94+ T cells migrate to the brain and predict multiple sclerosis severity.\nAbstract: Memory CD8+ T cells are central to multiple sclerosis (MS) and undergo clonal expansion, but disease-associated states remain incompletely defined. By single-cell profiling of circulating memory CD8+ T cells from patients with relapsing-remitting MS, healthy volunteers, and neuroinflammatory controls, we identified an MS-associated cytotoxic subset with NK-like features. These cells increase around relapse activity and belong to an oligoclonal reservoir. In an independent cohort sampled at the first clinical event, an elevated frequency of NK-like CD8+ T cells predicted an aggressive MS course two years later and was associated with a migratory/inflammatory program. Bulk and single-cell RNA-seq confirmed the NK-like transcriptional signature, and functional assays demonstrated TCR-independent cytotoxicity. Immunostaining and spatial transcriptomics revealed enrichment of these cells in MS lesions and a spatial association with macrophages/microglia. Together, our results identify a cytotoxic NK-like CD8+ T-cell subset that links peripheral inflammation to CNS lesions and may serve as an early biomarker of MS severity.\n\nID: 42377668\nTitle: Near\u2011Infrared Photobiomodulation in White\u2011Matter Disease: From Microglial States to Measurable Endpoints.\nAbstract: White-matter (WM) injury contributes to disability across multiple sclerosis, traumatic brain injury, Alzheimer's disease and related dementias, and small-vessel disease. We use microglial state programs as an organizing axis for WM injury-to-repair logic, while emphasizing that WM outcomes are multicellular and involve oligodendrocyte-lineage cells, astrocytes, axons/neurons, and vascular factors. Microglia span an injury-repair continuum, from inflammatory programs that increase oxidative stress and debris burden to repair-competent programs that support debris handling, remyelination, and axonal integrity. Near-infrared photobiomodulation (PBM; ~800-1100\u00a0nm) is most consistently associated with modulation of mitochondrial redox/bioenergetic pathways and inflammatory tone. CCO-centered mechanistic framing is best established near ~\u2009800-850\u00a0nm, whereas longer wavelengths (e.g., ~\u20091064-1070\u00a0nm) may involve additional initiating mechanisms with downstream convergence on shared redox/bioenergetic and inflammatory pathways. Across demyelination and spinal cord injury models, appropriately dosed PBM has been reported to reduce inflammatory glial readouts and to associate with improved myelin/axon-related endpoints and functional measures, although mechanistic certainty varies across models. Human evidence remains early but broadly supports safety; a randomized trial in moderate traumatic brain injury reported treatment-related changes in diffusion-MRI WM metrics, while small dementia and chronic-injury studies report heterogeneous cognitive and physiological signals. Given dose dependence and depth-limited transcranial delivery, we synthesize mechanism-informed, dose-aware reporting guidance and WM-anchored outcome frameworks that pair diffusion MRI/DTI with interpretable biomarkers (e.g., NfL, GFAP, sTREM2) and thermally controlled sham designs. We also note potential indirect/systemic contributions that could help reconcile depth-dose constraints with deeper WM effects.\n\nID: 42376811\nTitle: Longitudinal magnetic resonance spectroscopy study of metabolite changes over 2\u2009years in relapsing and primary progressive multiple sclerosis treated with ocrelizumab.\nAbstract: Magnetic resonance spectroscopy (MRS) offers non-invasive assessments of neuron-oligodendrocyte coupling and neuroinflammation to monitor treatment response in multiple sclerosis (MS). To track changes in N-acetylaspartate and myo-inositol in relapsing MS (RMS) and primary progressive MS (PPMS) patients treated with ocrelizumab over 2\u2009years. Single-voxel MRS at 3T was acquired at baseline in 10 healthy controls (HCs), and weeks 0, 12, 24, 52, and 96 in MS participants at a single center. Baseline myo-inositol was higher in PPMS than RMS (p\u2009=\u20090.047) and HC (p\u2009=\u20090.001), and correlated with disability across both MS groups (r\u2009=\u20090.57, p\u2009=\u20090.0006). Following treatment with ocrelizumab, both RMS and PPMS demonstrated declines in myo-inositol over time, returning toward HC levels (RMS p\u2009=\u20090.016; PPMS p\u2009=\u20090.004). Conversely, N-acetylaspartate was not different between groups and remained stable over time. Ocrelizumab treatment is associated with declining myo-inositol levels measured by MRS in both RMS and PPMS. Myo-inositol offers a unique biomarker to track resolution of gliosis and reactive microglia with treatment. Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

This Review explores immune signaling pathways in astrocytes, including pattern recognition through Toll-like receptors, nucleic acid sensors and inflammasomes. These pathways enable the detection of danger signals and initiate protective responses and endogenous innate immune functions. Downstream signaling pathways, including the interferon, NF-\u03baB and STAT3 pathways, mediate astrocyte reactivity and drive cytokine secretion, antiviral responses, phagocytosis and many other immune functions. While these responses are crucial for CNS health, their dysregulation can contribute to chronic inflammation and neurodegeneration in conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis. Additionally, astrocytes exhibit regional heterogeneity in their immune behaviors, which may influence disease trajectories. We highlight unresolved questions regarding the immune functions of astrocytes, their interplay with professional immune cells and their dual protective and pathological roles.\n\nID: 42368568\nTitle: Development of bacterial sonosensitizer hybrid systems to enhance cancer sono-immunotherapy.\nAbstract: Microorganisms can activate anti-tumor immune responses via the innate immune system. However, this immune effect lacks specificity, and prolonged stimulation by live bacterial colonization may lead to immune tolerance. Sonodynamic therapy triggers cellular death and lysis, fully activating the antigen presentation process by providing heterologous DNA and tumor antigen in situ. Herein, to enhance the immunological effect facilitated by ultrasonic treatment, a manganese-containing porphyrin-based metal-organic framework (Mn-MOF) was modified as an acoustic sensitizer on the surface of Escherichia coli to form bacterial sonosensitizer hybrid systems (HA@Mn-MOF@E). Importantly, HA@Mn-MOF@E was able to target and colonize 4T1 tumors due to the anoxic tendency of anaerobes. The ultrasound-induced bacterial and tumor cell death and released manganese could activate macrophages and dendritic cells (DCs) through the activation of the cGAS-STING pathway, which increased the proportion of CD3+ T cells and M1/M2 ratio within the tumor, as well as CD8+ effector T cells and CD86+ DCs in lymph nodes. By sono-sensitized immunotherapy, HA@Mn-MOF@E was demonstrated to inhibit orthotopic 4T1 tumor progression and induce tumor necrosis effectively. Such a designed bacterial sonosensitizer hybrid system offered the possibility of using sonodynamic assistance to sensitize live microorganisms-induced immunotherapy, with thorough activation of the antigen presentation in the tumor.\n\nID: 42367807\nTitle: Modulation of the immunological and neuroinflammatory microenvironment in older people with multiple sclerosis.\nAbstract: Life expectancy and the age at onset of multiple sclerosis (MS) are increasing, and a growing proportion of people with MS (pwMS) are now older than 55-60 years. Aging modifies MS pathobiology, with the dominant disease mechanisms moving from focal, relapse-driven inflammation to chronic, compartmentalized neuroinflammation and neurodegeneration. In this narrative review, we summarize current knowledge on the relationship between brain aging and MS, integrating clinical, radiological, pathological and therapeutic evidence. We first discuss mechanisms of immunosenescence and \"inflammaging\", including changes in adaptive and innate immunity, gut microbiota dysbiosis, mitochondrial dysfunction and blood-brain barrier dysfunction, and how these processes favor microglial activation, slowly expanding lesions, smouldering MS and progression independent of relapse activity. We then examine the impact of age on disability trajectories, cognitive decline and comorbidities, and the role of vascular and neurodegenerative mechanisms. The review also addresses age-related changes in safety and efficacy of disease-modifying therapies (DMT), with a focus on high-efficacy DMT, de-escalation and discontinuation strategies, and the management of infections, malignancies and polypharmacy in older pwMS. Finally, we describe new approaches relevant to this population, including Bruton's tyrosine kinase inhibitors, neuroprotective and remyelinating agents, advanced cellular therapies and lifestyle-based interventions. We conclude by outlining practical implications for personalized treatment decisions in older pwMS and open questions that future clinical trials and biomarker studies must address.\n\nID: 42364698\nTitle: A bone-marrow-homing biomimetic STING nanoinhibitor alleviates radiation-induced hematopoietic injury via modulating macrophage polarization.\nAbstract: Ionizing radiation-induced damage to the hematopoietic system is largely driven by STING activation-promoted M1 macrophage polarization and its resultant inflammation. However, effective suppression of pro-inflammatory macrophage polarization for treating radiation-induced hematopoietic stem cell injury is largely hindered by the inherent physiological barriers of bone marrow-targeted drug delivery. In this study, we develop a STING nanoinhibitor composed of poly(lactic-co-glycolic acid) nanoparticle loaded with a STING inhibitor and surface-coated senescent neutrophil membrane for targeted treatment of ionizing radiation-induced hematopoietic injury. Our STING nanoinhibitor can home to bone marrow via the CXCR4/SDF-1 axis and be phagocytosed by macrophages to shift activated pro-inflammatory M1 macrophages to the anti-inflammatory M2 phenotype through suppressing cGAS-STING signaling, and this STING inhibition can further reduce radiation-induced reactive oxygen species (ROS) accumulation to reduce M2-to-M1 macrophage polarization. In irradiation-treated mouse models, the STING nanoinhibitor preferentially accumulates in bone marrow to alleviate pancytopenia, preserve bone marrow architecture, and accelerate hematopoietic recovery while avoiding significant side effects. This study highlights the targeted modulation of bone marrow macrophages as a promising strategy for promoting hematopoietic cell recovery from radiation-induced injury.\n\nID: 42364313\nTitle: Occlusal abnormalities and temporomandibular joint osteoarthritis: A narrative review of cross-scale mechanical-metabolic-immune mechanisms.\nAbstract: To synthesize recent multiscale evidence and propose a unified mechanical-metabolic-immune framework for the role of occlusal abnormalities in temporomandibular joint osteoarthritis (TMJOA) pathogenesis. A narrative literature search was conducted in PubMed/MEDLINE, Scopus, and Web of Science for English-language articles published between January 2011 and April 2026. Search terms combined concepts related to temporomandibular joint osteoarthritis, malocclusion or occlusal abnormalities, mechanotransduction, Piezo1, integrin signaling, mitochondrial dysfunction, cGAS-STING activation, single-cell transcriptomics, macrophages, and sexual dimorphism. Clinical, imaging, animal, cellular, omics-based, and mechanistic studies relevant to TMJOA were narratively synthesized. Occlusal abnormalities may alter mandibular kinematics and joint stress distribution, thereby activating mechanotransduction through Piezo1, integrins, and related developmental feedback loops. Sustained mechanical overload may promote calcium dysregulation, endoplasmic reticulum stress, mitochondrial dysfunction, and activation of the cGAS-STING pathway. These changes can shift cellular metabolism toward increased glycolysis and contribute to a pro-inflammatory microenvironment. Single-cell and lineage-tracing evidence further suggests that sex-related immune regulation, including macrophage ontogeny and Xist-associated inflammatory responses, may contribute to the female predominance of temporomandibular joint disorders, although TMJ-specific validation remains needed. TMJOA progression can be interpreted as a cross-scale process in which abnormal occlusal loading links biomechanical stress, metabolic dysfunction, and immune remodeling. These pathways may represent potential targets for future mechanism-based diagnosis and therapy.\n\nID: 42363912\nTitle: Characterizing the Reactive Metabolites of Colony-Stimulating Factor 1 Receptor Inhibitor PLX5622 in Liver Microsomes and Mice.\nAbstract: Colony-stimulating factor 1 receptor (CSF1R) is a receptor tyrosine kinase involved in cell growth and differentiation, particularly in macrophages and microglia. CSF1R inhibitors are under investigation for various diseases, including cancer, autoimmune/inflammatory diseases, and neurodegenerative disorders. PLX5622 is a highly specific, brain-penetrant, and orally bioavailable CSF1R inhibitor that is being evaluated in a clinical trial for rheumatoid arthritis and considered as an attractive candidate for the treatment of Alzheimer's disease (AD). Drug metabolism significantly influences both the efficacy and safety of therapeutic agents. In particular, bioactivation leading to the formation of reactive metabolites is often implicated in adverse drug effects. In this study, we investigated the metabolism and potential bioactivation of PLX5622 in mouse and human liver microsomes (MLM/HLM) and mice using LC-MS-based metabolomic approaches. Reduced glutathione (GSH) and methoxyamine (NH2OMe) were used to capture reactive intermediates. In total, 12 PLX5622-GSH adducts and five NH2OMe adducts were identified in both HLM and MLM, along with 22 nontrapped metabolites generated from demethylation, hydroxylation, and carbon-carbon cleavage reactions. PLX5622-GSH-related adducts in mice were also assessed and 8 GSH adducts were detected in mouse liver, confirming the occurrence of bioactivation in vivo. Using recombinant human cytochrome P450 (CYP) enzymes and selective chemical inhibitors in liver microsomes, CYP3A was determined to be the primary enzyme responsible for the metabolic activation of PLX5622. These insights into the metabolic pathways of PLX5622 are valuable for further study of its safety and potential drug interactions of CYP3A. Future studies using human primary hepatocytes or physiologically human-relevant models such as liver-on-a-chip systems are warranted to confirm clinical relevance and better predict in vivo outcomes.\n\nID: 42360583\nTitle: Machine learning-driven prioritization and experimental validation of traditional Chinese medicine-derived STING-inhibitory candidates.\nAbstract: The stimulator of interferon genes (STING) is a key signalling adaptor in the cGAS-STING pathway of the innate immune system and plays a significant role in autoimmune diseases, viral infections, and cancer, thus representing a promising target for small-molecule inhibitor therapies. This study presents an integrated multidimensional computer-aided drug design (CADD) approach that utilises machine learning (ML), molecular docking, molecular dynamics (MD) simulations, and ADMET prediction to efficiently prioritize\u00a0new STING expression\u00a0suppressor candidates from natural products. We developed a precise ML-based STING classification model with 90.2% accuracy and a robust STING inhibitor activity regression model demonstrating strong predictive capabilities, as evidenced by an R2 of 0.826, MAE of 0.357, and RMSE of 0.452. Virtual screening across multiple traditional Chinese medicine (TCM) compound libraries (Tao Shu L6810, TCMIO, TCMBank, and HERB) yielded 1,596 compounds with predicted pIC50\u2009\u2265\u20097.00. After a rigorous multistep screening, seven compounds were selected for ADMET evaluation and experimental validation. Notably, two natural compounds, Cassiaside and Plantaginin, showed inhibitory activity on STING protein expression in THP-1-derived macrophages, and MD simulations, along with CETSA experiments, further validated their stable binding to the STING protein. Collectively, this study provides a robust and accurate ML-driven strategy for STING-Inhibitory Candidates discovery and prioritized two promising TCM-derived lead compounds that offer valuable structural scaffolds for the rational design of STING-targeted therapeutics against immune and inflammatory diseases.\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: 42358739\nTitle: The central role of radiotherapy in remodeling the tumor immune microenvironment: mechanisms and therapeutic implications.\nAbstract: Radiotherapy is an essential component of multidisciplinary cancer treatment. Its role has expanded from conventional local tumor eradication to active regulation of the tumor immune microenvironment. In recent years, emerging radiotherapy strategies, including FLASH radiotherapy, boron neutron capture therapy, lattice radiotherapy, spatially fractionated radiation therapy, precision particle therapy, immunomodulatory stereotactic body radiotherapy, and immune-optimized carbon ion therapy, have provided new opportunities to improve tumor control, reduce normal tissue toxicity, and overcome radioresistance. Radiotherapy can induce DNA damage and immunogenic cell death, promote tumor antigen release, enhance dendritic cell maturation and antigen cross-presentation, and increase CD8+ T-cell infiltration and antitumor immunity through the cGAS-STING type I interferon pathway. However, radiotherapy may also trigger immunosuppressive feedback, including the accumulation of myeloid-derived suppressor cells, tumor-associated macrophages, and regulatory T cells, as well as the upregulation of immune checkpoint molecules such as programmed death-ligand 1 (PD-L1). These changes may limit antitumor immune responses and contribute to radioresistance. Combining radiotherapy with immune checkpoint inhibitors can amplify antitumor immunity, but therapeutic efficacy is influenced by dose fractionation, treatment timing, tumor type, and baseline immune status. This mini review summarizes emerging radiotherapy strategies and their regulatory effects on the tumor immune microenvironment, and discusses the mechanistic basis, current challenges, and future directions of radiotherapy combined with immunotherapy.\n\nID: 42357265\nTitle: Camptothecin Nanowires Induce the cGAS-STING Pathway to Remold Tumor-Associated Macrophages for Antitumor Immunity.\nAbstract: Background/Objectives: This study aimed to develop a novel tumor-associated macrophage (TAM)-targeting nanoplatform to improve the solubility and bioavailability of camptothecin (CPT) and achieve active targeted drug delivery for enhanced anti-tumor immunotherapy. Methods: We constructed a sialic acid-disulfide bond-camptothecin (SA-SS-CPT) nanowire system. Sialic acid was used as a targeting ligand to specifically recognize the overexpressed Siglec-E receptor on TAMs. Upon cellular internalization, the disulfide bond was designed to respond to intracellular glutathione (GSH), enabling controlled drug release. Results: The SA-SS-CPT nanowires significantly improved CPT solubility and enabled targeted delivery to TAMs. Following GSH-responsive cleavage and CPT release, the nanowires induced DNA damage in TAMs, activating the cGAS-STING signaling pathway. This promoted TAM polarization toward the M1 phenotype, enhanced pro-inflammatory and anti-tumor immune responses, and inhibited tumor immune escape. Furthermore, SA-SS-CPT synergistically improved the efficacy of PD-L1 blockade immunotherapy, remodeling the tumor immune microenvironment. Conclusions: The SA-SS-CPT nanoplatform effectively targets TAMs, repolarizes them to an anti-tumor M1 phenotype, and activates the cGAS-STING pathway. It shows strong potential for overcoming tumor immune escape and synergizing with PD-L1 checkpoint blockade to achieve significant tumor clearance.\n\nID: 42356438\nTitle: Zhi-Zi-Chi Decoction Alleviates Depressive-like Behaviors by Regulating Gut Microbiota and Targeting the AMPK/PI3K-TOR Pathway via Its Metabolite Protocatechuic Acid.\nAbstract: Background: Neuroinflammation and gut-brain axis (GBX) dysregulation are key pathological drivers of stress-related neuropsychiatric disorders. Zhi-Zi-Chi Decoction (ZZCD), a classic Traditional Chinese Medicine (TCM) formula, has been clinically used to alleviate mental disturbances via the TCM principle of \"clearing heat and relieving restlessness.\" Still, its modern neuroprotective mechanisms, especially its links to gut microbiota and central signaling pathways, remain incompletely elucidated. Purpose: This study aimed to systematically investigate the therapeutic effects of ZZCD on chronic restraint stress (CRS)-induced neurodysfunction in mice and clarify its mechanisms from the perspectives of TCM theory, material basis, gut microbiota-metabolite axis, and central signaling pathways. Method: CRS mice were treated with ZZCD or protocatechuic acid. Behavioral tests evaluated depression- and anxiety-like behaviors. UHPLC-Q-TOF/MS identified ZZCD's chemical constituents; 16S rRNA sequencing and untargeted metabolomics analyzed gut microbiota and metabolite changes. Western blot, immunofluorescence, and proteomics examined neuroinflammation, microglial polarization, and signaling pathway activity (PI3K/Akt/mTOR, AMPK). Results: ZZCD reversed CRS-induced depression- and anxiety-like behaviors and suppressed neuroinflammation. Mechanistically, UHPLC-Q-TOF/MS identified 424 ZZCD constituents, with prenol lipids, organooxygen compounds, and flavonoids as the most abundant. ZZCD reversed CRS-induced imbalance in gut microbiota, reducing pro-inflammatory Prevotella and enriching beneficial Lactobacillus, and mediated the enrichment of the prebiotic metabolite PCA in colonic and serum samples, which crossed the blood-brain barrier (BBB) to exert neuroprotection. Additionally, ZZCD and PCA normalized the PI3K/Akt/mTOR pathway and activated AMPK, promoting M2 microglial polarization and restoring synaptic plasticity. Conclusions: ZZCD exerts antidepressant effects by a gut-microbiota-dependent modulation of PCA-PI3K/Akt/mTOR and AMPK dual axes that converts microglia from M1 to M2, providing ethnopharmacological evidence and a mechanistic rationale for its clinical application in major depressive disorder.\n\nID: 42354813\nTitle: BTNL2 Inhibits Pyroptosis in H37Ra-Infected Macrophages by Maintaining Mitochondrial Homeostasis.\nAbstract: Butyrophilin-like 2 (BTNL2) is an immunomodulatory molecule critically involved in regulating the host immune response to infection with the avirulent Mycobacterium tuberculosis strain H37Ra. However, its functional role in modulating pyroptosis and associated inflammatory responses remains incompletely characterized. Here, we demonstrate that BTNL2 deficiency exacerbates pyroptosis and the inflammatory response in H37Ra-infected murine peritoneal macrophages via two distinct pathways. First, the loss of BTNL2 induces excessive mitochondrial damage, which leads to aberrant release of mitochondrial DNA (mtDNA) and accumulation of mitochondrial reactive oxygen species (mtROS), thereby triggering NLRP3 (NOD-like receptor family pyrin domain containing 3) inflammasome activation and gasdermin D (GSDMD)-mediated pyroptosis. Second, cytosolic mtDNA accumulation hyperactivates the cGAS-STING signaling axis, resulting in transcriptional upregulation of NLRP3 and consequent amplification of pro-inflammatory cytokine production. Collectively, these findings demonstrate that BTNL2 acts as a regulator of mitochondrial homeostasis and innate immune balance during H37Ra infection in primary peritoneal macrophages. The results provide mechanistic insights into BTNL2 function in the context of H37Ra-induced pyroptosis.\n\nID: 42353155\nTitle: Early Combined B-Cell Depletion and BTK Inhibition Reduced TLS-like Structures and Relapse in PLP139-151-Induced EAE.\nAbstract: B-cell-depleting therapies have revolutionized multiple sclerosis (MS) treatment, yet relapses persist in some patients-suggesting additional pathogenic drivers beyond peripheral B cells. Tertiary lymphoid structures (TLS) are extensively documented in progressive MS at autopsy, but whether their formation begins during the relapsing-remitting phase and how they evolve during the transition to progression remain undefined. Here, using the relapsing-remitting PLP139-151-induced EAE model, we uncover that TLS-like structures form in the subventricular zone during relapse, once established, persist through remission as niches containing both B cells and persistently activated microglia. Neither B-cell depletion alone nor BTK inhibition alone fully prevents relapse. Strikingly, early combined B-cell depletion and BTK inhibition virtually abolishes TLS-like structure formation and may effectively prevent complete disease relapse in this model. By contrast, late initiation of the same combination fails to resolve existing TLS-like structures or prevent relapse, although it attenuates disease severity. These data indicate that established TLS-like structures may represent treatment-resistant compartments, and that both B cells and microglia may be crucial during early formation for sustaining their disease relapse-driving activity. Our study confirms that TLS-like structures may be a key factor driving the compartmentalization of central nervous system inflammation, points to a potentially narrow therapeutic window for intervention, and proposes that early combined B-cell depletion and BTK inhibition may represent a promising strategy worthy of further investigation.\n\nID: 42351725\nTitle: Antioxidant, Redox, and Immunomodulatory Effects of Hypericum perforatum in the Galleria mellonella: A 3R-Oriented Invertebrate Model.\nAbstract: Background/Objectives: Hypericum perforatum L. (St. John's Wort) is extensively utilized in ethnopharmacology due to its anti-inflammatory and immunomodulatory properties. However, its effects on the interaction between innate immunity and oxidative homeostasis remain incompletely characterized, particularly in alternative invertebrate models. This study aimed to evaluate the effects of H. perforatum extract on oxidative homeostasis and protein metabolism using the Galleria mellonella model, a 3R-compliant and ethically sustainable platform for preliminary immunological and redox-related screening. Methods: Last instar G. mellonella larvae were administered increasing concentrations of H. perforatum extract (0.001-20 mg mL-1) by intrahemocoelic injection. After 24 h, hemolymph samples were analyzed for total protein (TP), total hemocyte count (THC), encapsulation and melanization responses, superoxide dismutase (SOD) activity, catalase (CAT) activity, and malondialdehyde (MDA) levels. The phytochemical profile of the extract was additionally evaluated using GC-MS analysis. Results: Significant group-dependent alterations were observed in TP levels and THC values, with the HP-2 group demonstrating the highest hemocyte counts and enhanced strong encapsulation responses. Higher extract concentrations, particularly HP-4, were associated with increased weak encapsulation profiles, suggesting altered cellular immune organization. Melanization responses became significantly elevated at 24 h following treatment. In contrast, SOD activity, CAT activity, and MDA levels did not differ significantly among groups, indicating preservation of oxidative homeostasis under the tested conditions. Conclusions: H. perforatum extract induced dose-dependent modulation of cellular and humoral immune responses in G. mellonella without evidence of detectable oxidative disruption during acute exposure. These findings support the utility of the G. mellonella model for preliminary evaluation of botanical immunomodulators and suggest that H. perforatum may influence immunophysiological pathways independently of overt oxidative toxicity.\n\nID: 42350827\nTitle: Donor-specific pathological features associate with genetic background, lesion type distribution, and clinical heterogeneity in multiple sclerosis.\nAbstract: Multiple sclerosis (MS) shows pronounced pathological and clinical variability between individuals, reflecting differences in genetic susceptibility, inflammatory activity, and tissue repair. This variability complicates efforts to relate lesion pathology to clinical trajectories. In previous work in the Netherlands Brain Bank MS autopsy cohort (NBB-MS), we showed that relative proportions of different lesion types, lesion load, and microglia/macrophage activity score, associate with clinical severity, while also revealing marked inter-individual variability. Here, we extend these observations by examining whether selected donor-specific pathological features relate to genetic background, quantitative lesion type distributions, and clinical disease course, and thereby help contextualize this heterogeneity.Brain tissue from 287 NBB-MS donors was assessed for the presence of the donor-specific pathological features, namely perivascular cuffs, microglial nodules, broad rim lesions (BRLs), and remyelination efficiency. Perivascular cuffs and microglial nodules were more prevalent among carriers of the MS susceptibility allele HLA-DRB1*15:01 (rs3135388). BRLs and perivascular cuffs were enriched in carriers of the MS severity-associated SNP in the DYSF-ZNF638 locus (rs10191329). Perivascular cuffs associated with increased microglia/macrophage activation score and decreased age at death. Microglial nodules in the normal appearing white matter associated with a higher proportion of active lesions. BRLs were linked to increased proportions of active and mixed active/inactive lesions, higher brainstem lesion rate, and a higher age related MS severity score. Poor remyelination efficiency associated with a higher proportion of mixed active/inactive and inactive lesions, and a shorter disease duration.Together, these findings show that specific pathological features of donors relate to genetic risk, lesion type distribution, and clinical outcome. Integrating these donor-specific pathological features alongside lesion classification will enable a more biologically refined interpretation of post-mortem MS tissue study results and will improve understanding of inter-individual heterogeneity in MS.\n\nID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17\u202fA+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.\n\nID: 42398656\nTitle: Ethyl acetate extract of Poecilobdella manillensis Lesson ameliorates ischemia stroke through inhibiting cell apoptosis and suppressing TLR4/NF-\u03baB-mediates neuroinflammation.\nAbstract: Poecilobdella manillensis Lesson is a well-recognized medicinal leech in traditional Chinese medicine and Guangxi Zhuang ethnic medicine. It has long been used to activate blood circulation and remove blood stasis for the treatment of ischemic stroke. Modern pharmacological research has verified its potent anticoagulant and anti-inflammatory activities. Current studies mainly focus on its polypeptide components that exert antithrombotic effects to improve cerebral ischemia, while the neuroprotective potential and related mechanisms of its small-molecule constituents remain largely unclear. This study aimed to investigate the therapeutic effects of the ethyl acetate extract (EA) of P. manillensis on cerebral ischemia-reperfusion injury and to clarify its underlying molecular mechanism. The chemical constituents of EA were identified by UPLC-Q-TOF-MS/MS. Network pharmacology and molecular docking were used to predict and verify core targets and pathways. Neuroprotective and anti-inflammatory effects of EA were evaluated in a rat MCAO/R model, OGD/R-injured SH-SY5Y cells, and LPS-stimulated BV2 cells, using histological staining, Western blot, immunohistochemistry, and RT-qPCR. Seven small-molecule components were identified in EA, and 314 overlapping targets related to ischemic stroke were screened. Network analysis showed that TLR4 was the core target, and the main enriched pathways included NF-\u03baB, Toll-like receptor, apoptosis and TNF signaling pathways. Consistent with the predicted results, EA significantly reduced cerebral infarct volume and improved neurological deficits in MCAO/R rats, and inhibited neuronal apoptosis and microglial inflammation in vivo. In vitro, EA notably improved the survival of OGD/R-injured neurons and suppressed LPS-induced inflammatory responses in BV2 cells. Meanwhile, EA markedly downregulated the expression of TLR4/NF-\u03baB and NLRP3 inflammasome-related molecules. The present study demonstrated that EA protects against cerebral ischemia-reperfusion injury by inhibiting neuronal apoptosis and TLR4/NF-\u03baB-mediated neuroinflammation. These findings provide a scientific basis for the traditional clinical application of P. manillensis and suggest that EA could serve as a potential therapeutic candidate for ischemic stroke.\n\nID: 42395866\nTitle: The role of SUMOylation in regulating proteins that drive neuronal disease progression.\nAbstract: SUMOylation is a post-translational modification in which a Small Ubiquitin-like Modifier (SUMO) protein is reversibly attached to a lysine residue on a target protein in an ATP-dependent process. This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders.\n\nID: 42395216\nTitle: Human Exposure to Micro- and Nanoplastics and Their Potential Neurological Implications: A Systematic Review of Emerging Evidence.\nAbstract: The growing prevalence of micro- and nanoplastics (MNPs) in the environment elicits concerns about their possible impact on human neurological health. Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42392745\nTitle: [Investigation of antidepressant active components and mechanisms of total triterpenoids of Wolfiporia cocos based on serum pharmacochemistry combined with network pharmacology and experimental validation].\nAbstract: Based on the total triterpenoids of Wolfiporia cocos(TTWC) in the serum of depressed rats, this study combined network pharmacology, molecular docking, and experimental validation to explore the antidepressant active components and mechanisms of TTWC. Firstly, ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was used to identify the blood-entering components of TTWC. Then, network pharmacology and molecular docking were used to predict the potential antidepressant active components and mechanisms of TTWC. Finally, an in vitro model constructed using lipopolysaccharide(LPS)-treated BV2 cells was used to validate the main active components. A total of 38 triterpenoid components of W. cocos were detected in the blood. Thirty potential active components were obtained through screening by network pharmacology, and 122 component-disease overlapping targets were obtained, which showed that interleukin(IL)-6, tumor necrosis factor(TNF), Albumin(ALB), non-receptor tyrosine kinase(SRC), and IL-1\u03b2 might be the core targets. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment results indicated that the antidepressant effect of TTWC might be influenced by neuroactive ligand-receptor interaction signaling pathway, Fc \u03b5 RI signaling pathway, TNF signaling pathway, and mitogen-activated protein kinase(MAPK) signaling pathway. The molecular docking results showed that the potential antidepressant active components of TTWC had a good binding effect with the core targets. The results of cell assays showed that TTWC and nine components, including pachymic acid and pachymic acid A, reduced the secretion levels of tumor necrosis factor-\u03b1(TNF-\u03b1), IL-6, IL-1\u03b2, IL-18, and nitric oxide(NO) to varying degrees and down-regulated the protein expression levels of phosphorylated p38 mitogen-activated protein kinase(p-p38) and phosphorylated c-Jun amino-terminal protein kinase(p-JNK). Comparison of the results of the experiments in each group showed that there were differences in the potency and main targets of the components. On the basis of previous studies, the present study explored the antidepressant active components of TTWC and demonstrated that they can effectively reduce the secretion of inflammatory factors and inflammatory mediators, and realize the control of neuroinflammation through the regulation of the MAPK pathway. The results of this study showed that TTWC inhibited neuroinflammation in a multi-component, multi-target, and multi-pathway manner, thus realizing the antidepressant effect.\n\nID: 42391630\nTitle: Helicobacter pylori infection and neurological disorders: association, mechanisms, and clinical implications.\nAbstract: Helicobacter pylori infects nearly half of the global population and has traditionally been viewed as a pathogen restricted to the gastric mucosa. Growing evidence, however, suggests that chronic infection may exert systemic effects extending to the central nervous system. This review critically examines the potential neurological implications of H.\u00a0pylori infection within the emerging framework of the gut-brain axis. We performed a narrative, hypothesis-generating review of human observational and interventional studies complemented by mechanistic experimental research. The literature was evaluated with particular attention to study design, heterogeneity, and potential confounding in reported associations between H.\u00a0pylori infection and neurological disorders. Across multiple studies, H.\u00a0pylori infection has been linked to a modestly increased prevalence of Parkinson's disease and dementia, although findings remain heterogeneous. In Parkinson's disease, infection may exacerbate motor fluctuations and reduce levodopa bioavailability, with partial clinical improvement reported following eradication in selected patients. Experimental studies further demonstrate that bacterial outer membrane vesicles can access the brain and promote neuroinflammatory and amyloidogenic processes, supporting biological plausibility. By contrast, several epidemiological studies report an inverse association with multiple sclerosis, suggesting potential immunomodulatory effects. Evidence relating H.\u00a0pylori to migraine and mood disorders remains inconsistent. Current data do not support H.\u00a0pylori as a primary cause of neurological disease. Instead, the infection may act as a context-dependent modifier within the complex inflammatory and immunometabolic networks of the gut-brain axis. Clarifying this relationship will require prospective studies integrating microbial strain profiling, biomarker-defined neurological phenotypes, and adequately powered interventional trials.\n\nID: 42391599\nTitle: Factors Associated With Disability Improvement and Worsening Independent of Attacks in Patients With AQP4-IgG+ NMOSD and MOGAD: A Multicenter Cohort Study.\nAbstract: Disability trajectories in aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorder (AQP4-IgG+ NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are primarily driven by attack-related damage. Confirmed disability worsening (CDW) independent of attacks has been described but occurs infrequently in AQP4-IgG+ NMOSD and MOGAD. Confirmed disability improvement (CDI) has not been evaluated in large cohorts. We determined the frequency of CDI and CDW independent of attacks and identified clinical factors associated with these outcomes in AQP4-IgG+ NMOSD and MOGAD. This retrospective, multicenter cohort study analyzed data from the German Neuromyelitis Optica Study Group (NEMOS) registry. Adult patients with AQP4-IgG+ NMOSD or MOGAD and longitudinal Expanded Disability Status Scale (EDSS) assessments were included. EDSS episodes were defined as periods with \u22653 EDSS assessments without attacks, obtained \u226590 days after attack. CDW and CDI were defined as sustained EDSS increase or decrease (\u22651.5 for baseline EDSS 0; \u22651.0 for EDSS 1.0-5.5; \u22650.5 for EDSS \u22656.0) confirmed after at least 6 months. The primary outcomes were annualized CDI and CDW rates. Risk factors were assessed using multivariable Anderson-Gill regression models. A total of 338 EDSS episodes of 307 patients (n: 202/105, median age at EDSS change: 56/41 years, 88/49% female, both p < 0.001; AQP4-IgG+ NMOSD/MOGAD) were included. Adjusted annualized CDI and CDW rates did not differ between AQP4-IgG+ NMOSD (CDI: 0.083, 95% CI 0.029-0.233; CDW: 0.025, 95% CI 0.007-0.092) and MOGAD (CDI: 0.057, 95% CI 0.012-0.277; CDW: 0.036, 95% CI 0.002-0.513). In AQP4-IgG+ NMOSD, a lower number of prior attacks was associated with higher CDI rates (hazard ratio [HR] 0.89, 95% CI 0.82-0.97). Younger age was associated with increased CDI rates in both AQP4-IgG+ NMOSD and MOGAD (HR 0.96, 95% CI 0.94-0.99, for both). CDI and CDW independent of attacks, although rare, occur in AQP4-IgG+ NMOSD and MOGAD. The association between fewer prior attacks and higher CDI rates in AQP4-IgG+ NMOSD underscores the importance of early attack prevention.

The mechanistic target of rapamycin (mTOR) pathway plays a key role in regulating immune responses, cell metabolism, autophagy, and repair processes. Although the role of mTOR in neurodegeneration has been explored in previous reviews, a systematic assessment of its function in MS across different models is still lacking. This systematic review aimed to examine the role of mTOR signaling in the pathophysiology of MS. Following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, we screened preclinical and clinical studies using two databases and assessed the risk of bias specific to the study types. A total of 189 records were identified, of which 90 met the\u00a0inclusion criteria for qualitative analysis. Studies using in vitro and in vivo (mainly rodent models, both sexes) models of MS, as well as MS patient tissue or data, consistently demonstrated that mTOR is involved in the MS-related processes neuroinflammation, myelination, autophagy, gliosis, mitochondrial dysfunction, and oxidative stress. mTOR inhibition reduces pro-inflammatory signaling and may enhance autophagy, offering neuroprotection. In contrast, activation of mTOR promotes remyelination by enhancing oligodendrocyte differentiation and maturation. These remyelinating effects may be masked in inflammatory environments, because activation of mTOR supports immune cell expansion and glial reactivity, inducing inflammation and oxidative stress. Overall, our findings underscore a dual role of mTOR in MS pathology, with important implications for disease stage and timing of intervention. Although mTOR is mechanistically important in MS, its therapeutic modulation is unlikely to be readily clinically translatable without a substantial risk of unintended and context-dependent effects.\n\nID: 42390621\nTitle: Supra-additive neuroprotective effects of berberine-metformin combination in diabetic encephalopathy: Chou-Talalay synergy quantification, AMPK-Nrf2 axis modulation, and pharmacokinetic verification.\nAbstract: Type 2 diabetes mellitus (T2DM) increases the risk of hippocampal neurodegeneration and cognitive decline. Berberine and metformin independently activate AMPK and may engage Nrf2-mediated antioxidant defenses, yet their combined neuroprotective interaction has not been formally quantified using validated synergy frameworks, nor has its pharmacokinetic basis been verified. Streptozotocin-nicotinamide diabetic rats were allocated to twelve groups (n\u2009=\u200913/group) receiving berberine (50, 100, 150\u00a0mg/kg/day) or metformin (100, 200, 300\u00a0mg/kg/day) monotherapy, fixed-ratio 1:2 combinations, or vehicle controls (including a non-diabetic combination group) orally for six weeks. The novel object recognition (NOR) discrimination index served as the predefined primary endpoint for Chou-Talalay combination index (CI) analysis. Hippocampal mechanistic (n\u2009=\u20096/group) and satellite LC-MS/MS pharmacokinetic (n\u2009=\u20096/group) analyses were performed. Diabetes impaired NOR discrimination index (37.2\u2009\u00b1\u20093.8% vs. 68.4\u2009\u00b1\u20093.2%; p\u2009<\u20090.001). The reference combination (100\u2009+\u2009200\u00a0mg/kg) restored NOR to 67.1\u2009\u00b1\u20093.6% with CI\u2009=\u20090.65 (95% CI: 0.43-0.91), synergism maintained across the full effect range. All six neuroinflammatory endpoints achieved Benjamini-Hochberg-corrected significance (p_adj\u2009=\u20090.006-0.043; Tier 2). Non-diabetic combination animals showed reduced AMPK activation magnitude (1.53 vs. 2.31-fold; P_adj\u2009=\u20090.067; Tier 3, hypothesis-generating). LC-MS/MS verified bioequivalent drug exposure. Berberine-metformin co-treatment is associated with CI-quantified supra-additive recognition memory recovery in diabetic encephalopathy, with neuroinflammatory suppression as the most statistically robust mechanistic correlate. Pharmacokinetic findings are consistent with a pharmacodynamic rather than pharmacokinetic basis. Causal involvement of the AMPK-Nrf2 axis remains correlative pending direct loss-of-function validation.\n\nID: 42390174\nTitle: Proteomic Profiling of Optic Nerves From SMOX-Deficient Mice Identifies Regulators of Neuroinflammation and Axonal Damage in Optic Neuritis.\nAbstract: Visual dysfunction due to optic neuritis (ON) is an early clinical manifestation of multiple sclerosis (MS). ON is characterized by inflammation of the optic nerve, demyelination, axonal damage, and retinal ganglion cell (RGC) loss. Previously, we showed that spermine oxidase (SMOX), a polyamine catabolizing enzyme, modulates visual function in an experimental model of ON. Using proteomic analysis, the present study aimed to identify SMOX-regulated molecular pathways involved in ON-associated visual dysfunction. Experimental autoimmune encephalomyelitis (EAE) was induced in wild-type (WT) and SMOX-deficient (Smox KO) mice. Clinical scoring of mice was recorded daily. Optic nerves from WT and Smox KO EAE mice and their controls were collected and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pathway enrichment and comparative analyses were performed to identify key processes and pathways regulated by SMOX. Immunofluorescence was performed to detect changes in the expression of key proteins. Smox KO EAE mice showed delayed and reduced clinical scores. Pathway enrichment analysis identified several key processes affected in EAE, including regulation of the actin cytoskeleton, tight junction integrity, and platelet activation/aggregation. The comparative analysis of the WT EAE and Smox KO EAE proteomes, together with false discovery rate (FDR)-corrected pathway enrichment analysis, indicated attenuation of neuroinflammatory pathways in the SMOX-deficient optic nerve. Furthermore, SMOX deficiency restored key cytoskeletal and cellular-adhesion proteins essential for neuronal integrity. Immunofluorescence studies confirmed dysregulation of receptor for activated C kinase 1 (RACK1), actinin alpha 4 (ACTN4), high mobility group box 1 (HMGB1), and S100 calcium-binding protein B (S100B), critical proteins involved in immune signaling, cytoskeletal stability, and inflammation. These findings indicate the impact of SMOX on inflammation and cytoskeletal stabilization in ON and its potential as a therapeutic target in preserving vision in MS.\n\nID: 42388566\nTitle: Insights from LC-MS-based cerebrospinal fluid metabolomics in tuberculous meningitis.\nAbstract: Tuberculous meningitis (TBM) remains the most devastating form of extra-pulmonary tuberculosis (TB) and is associated with high mortality and neurological deficits, often due to delayed diagnosis. Disease outcome in TBM depends critically on early diagnosis and timely initiation of treatment. However, the non-specific clinical presentation of TBM poses a major diagnostic challenge, as no single test can reliably establish a definitive diagnosis. The recommended diagnostic approach, GeneXpert MTB/RIF ultra, combined with mycobacterial culture of cerebrospinal fluid (CSF), remains limited by suboptimal sensitivity and restricted availability in many resource-constrained settings. These limitations underscore the urgent need for novel biomarkers that reflect TBM-specific pathophysiology and enable a single rapid, reliable, and accessible diagnosis. This perspective paper draws on insights from LC-MS-based CSF metabolomic profiling to highlight metabolic alterations in TBM. Key metabolic pathways-fatty acid \u03b2-oxidation reflected by altered acylcarnitine profiles, amino acid perturbations, and the tryptophan-kynurenine pathway-are discussed in relation to cellular energy disruption and neuroinflammation. Based on these alterations, free carnitine and quinolinic acid emerge as priority candidates for further investigation. Free carnitine reflects TBM-associated energy dysregulation, while quinolinic acid appears to mirror the severity of neuroinflammation. Future studies should focus on validating these metabolites in independent cohorts and on assessing their translational potential in more readily accessible biofluids, with the ultimate goal of enabling simplified, widely implemented diagnostic assays.\n\nID: 42387307\nTitle: Baseline Neuroinflammation Stratifies TSPO-PET Response to Disease-Modifying Therapy in Multiple Sclerosis.\nAbstract: To investigate which baseline clinical and imaging characteristics best predict TSPO-PET-measurable reduction in glial activation following treatment of multiple sclerosis (MS), to utilize this information for designing more efficient biomarker-based clinical trials targeting glial activation. This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS.\n\nID: 42386214\nTitle: Anti-Ma2 encephalitis: when the examination localises beyond MRI.\nAbstract: \n\nID: 42383392\nTitle: Role of Toll-like receptors and oral-gut-brain axis in neurodegenerative and neuropsychiatric disorders.\nAbstract: The oral-gut-brain axis is a path connecting the gastrointestinal tract and the central nervous system (CNS). The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders. Because the contributing factors have not been fully understood yet, further studies could help provide novel therapeutic opportunities.\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.

Recent advances have fundamentally reshaped our understanding of how microglial mitochondrial metabolism influences neuroinflammation and disease progression. Single-cell transcriptomics has revealed unexpected metabolic heterogeneity, identifying distinct phenotypes such as disease-associated microglia (DAM) and lipid-laden microglia (LLM) that represent not merely activated states but terminal endpoints of metabolic paralysis. These discoveries converge on a unified pathogenic mechanism: mitochondrial quality control failure leads to mitochondrial DNA release, which activates the cGAS-STING pathway to create an \"epigenetic lock\" that drives sustained neuroinflammation. Interestingly, we highlight that the loss of metabolic flexibility-rather than glycolysis per se-is the true driver of pathology, explaining why the same metabolic shift can be protective during acute injury but pathological when sustained chronically. We critically examine conflicting evidence across Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ischemic stroke, including the puzzling dual roles of glycolysis, controversies surrounding the experimental autoimmune encephalomyelitis (EAE) model in multiple sclerosis research, and the paradoxical worsening of stroke outcomes following microglial depletion. By synthesizing these mechanistic insights with lessons from failed clinical trials, we identify critical translational gaps-including the lack of longitudinal human data and validated biomarkers-and propose a precision medicine framework focused on restoring mitochondrial dynamics and metabolic flexibility in neurological diseases.\n --- END ACTUAL ABSTRACT FOR 41484491 ---\n\n- ERROR: You cited ID: 41063265 for the quote: \"Intracerebral MHV68 infection induced mild brain demyelination and ataxia ... administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus.\"\n FACT: Ellipses (...) are strictly forbidden.

The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development.\n --- END ACTUAL ABSTRACT FOR 41063265 ---\n\n- ERROR: You cited ID: 40275354 for the quote: \"Our data demonstrate in an array of mouse models, including active/passive-EAE and transgenic mice, a microglia-Th17 feed-forward activation loop drives EAE disease progression through a mechanism dependent on both MHC-II, proinflammatory cytokines, inflammatory chemokines as well as STING\u2192NF-\u03baB pathway in the microglia.\"\n FACT: Strict Misquote Detected!

While studies have highlighted the distinct roles of microglia and Th17 cells in EAE, it remains unclear whether microglia, as potential professional antigen-presenting cells, activate and stabilize the effector program of EAE-pathogenic Th17 cells in vivo; and if so, whether the Th17 could in turn reinforce the active state of the microglia. Our data demonstrate in an array of mouse models, including active/passive-EAE and transgenic mice, a microglia-Th17 feed-forward activation loop drives EAE disease progression through a mechanism dependent on both MHC-II, proinflammatory cytokines, inflammatory chemokines as well as STING\u2192NF-\u03baB pathway in the microglia and effector cytokines produced by the pathogenic Th17 cells. We also captured and identified the molecular properties of the feed-forward loop, which are two-cell entities of microglia-Th17, and proved them as the functional units of antigen presentation and bi-directional activation between the two cell types. Moreover, ACT001, an orphan drug to treat glioblastoma, disrupts this feed-forward activation loop by inhibiting the STING\u2192NF-\u03baB pathway in microglia, thereby alleviating EAE. These findings emphasize the importance of interactions and bi-directional activations between microglia and Th17 in the autoimmune neuroinflammation, and provide rationale for further investigation on ACT001 as therapeutic option for autoimmune inflammatory diseases driven by similar mechanisms.\n --- END ACTUAL ABSTRACT FOR 40275354 ---\n\n- ERROR: You cited ID: 42406535 for the quote: \"Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. ...

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n --- END ACTUAL ABSTRACT FOR 42406535 ---\n\n- ERROR: You cited ID: 42383100 for the quote: \"Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression.

Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta. The review also explores the cytokine network biomarkers, CSF and serum signatures and single-cell immune states, as well as existing and new drugs. These include migration blockade, targeting of S1P-receptors, anti-CD20 therapy, targeting of Th17/GM-CSF and JAK-STAT pathways, low-dose IL-2, approaches of targeting antigens and engineered Tregs. Investigating the areas of stage and compartment-specific CD4+ T-cell circuits can help to advance targeted immunomodulation in progressive MS and neuro-repair.\n --- END ACTUAL ABSTRACT FOR 42383100 ---\n\n- ERROR: You cited ID: 42140444 for the quote: \"Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT, NF-\u03baB, inflammasome activation, and cGAS-STING signaling.\"\n FACT: Strict Misquote Detected!

Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks. In this review, we summarize current insights into the molecular and cellular roles of ISG15 in neuroinflammation, highlight its dual protective and pathogenic functions, and discuss therapeutic strategies and future directions for targeting ISG15-related pathways in CNS diseases.\n --- END ACTUAL ABSTRACT FOR 42140444 ---\n\n- ERROR: You cited ID: 42193931 for the quote: \"Viral infections of the central nervous system produce memory impairment through mechanisms that extend beyond acute neuronal injury. ... converge on four shared molecular pathways ... mitochondria-associated membrane (MAM) dysfunction, chronic neuroinflammation, blood-brain barrier (BBB) disruption, and impaired CREB-BDNF signaling.\"\n FACT: Ellipses (...) are strictly forbidden.

Herpes simplex virus type 1, human immunodeficiency virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, influenza, SARS-CoV-2, West Nile virus, and Zika virus each enter or engage the brain through distinct routes, yet converge on four shared molecular pathways that selectively damage hippocampal circuits: mitochondria-associated membrane (MAM) dysfunction, chronic neuroinflammation, blood-brain barrier (BBB) disruption, and impaired CREB-BDNF signaling. These pathways specifically compromise the dentate gyrus, CA3, and CA1 subfields, producing predictable deficits in pattern separation, associative retrieval, and temporal memory binding. Antiretroviral and antiviral therapies suppress viral replication but fail to reverse organelle-level dysfunction, leaving most hippocampal injury unaddressed. Emerging plasma biomarkers, p-tau217, neurofilament light chain, and GFAP, combined with hippocampal subfield MRI, now enable mechanistic stratification before irreversible circuit loss occurs. This review proposes, as a unifying hypothesis, that virus-associated memory impairment represents a convergent hippocampal syndrome driven by shared downstream pathways, and that combination therapies targeting these pathways simultaneously offer greater therapeutic promise than pathogen-specific approaches alone. The evidentiary basis for this framework varies across pathogens and conditions; direct mechanistic evidence, mechanistic analogy, and preclinical data are distinguished throughout.\n --- END ACTUAL ABSTRACT FOR 42193931 ---\n\n- ERROR: You cited ID: 42039182 for the quote: \"We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in 'sanctuary sites' like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV).\"\n FACT: Strict Misquote Detected!

While acute COVID-19 is generally milder in children due to a more robust innate immune response, the mechanisms driving the persistence of symptoms in PPCC remain incompletely understood and likely multifactorial. This narrative review synthesizes current epidemiological data and explores the \"perfect storm\" of immunological and pathophysiological alterations underpinning the condition. We examine critical hypotheses including a dysregulated immune response characterized by altered T-cell subsets, monocyte activation, and autoantibody production. We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in \"sanctuary sites\" like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV). Furthermore, the review details downstream pathogenic pathways, including vascular endothelial inflammation (thrombo-inflammation), neuroinflammation, and metabolic dysfunctions affecting the mitochondria and tryptophan-kynurenine pathway. Finally, we address the role of microbiome dysbiosis in perpetuating systemic inflammation and the gut-lung axis dysfunction. Given the heterogeneity of clinical presentations, we conclude that PPCC is likely a syndrome of overlapping biological phenotypes. Future research must prioritize identifying these specific biological endotypes to develop targeted diagnostic and therapeutic strategies for the pediatric population.\n --- END ACTUAL ABSTRACT FOR 42039182 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development.\" (Source: 42025559)\n- \"Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.\" (Source: 42397737)\n- \"Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens.\" (Source: 42125999)\n- \"When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS.\" (Source: 42253989)\n- \"Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role.\" (Source: 42401926)\n- \"Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism.\" (Source: 41702081)\n- \"HSY attenuated adverse cardiac remodeling following MI by inhibiting STING-mediated ZBP1-PANoptosome assembly and subsequent PANoptosis.\" (Source: 42025008)\n- \"Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events.\" (Source: 41265623)\n- \"The growing significance of three-dimensional (3D) brain organoids (BOs) derived from induced pluripotent stem cells (iPSCs) can be used as a groundbreaking platform for examining neurodegenerative pathways induced by exposure to environmental toxicants and viral infections.\" (Source: 42118409)\n- \"Here, robust activation of the cGAS-STING-IFN-I signaling pathway is identified in myeloid cells in both the periphery and central nervous system.\" (Source: 40686188)\n- \"From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.\" (Source: 42395866)\n- \"Here, using the relapsing-remitting PLP139-151-induced EAE model, we uncover that TLS-like structures form in the subventricular zone during relapse, once established, persist through remission as niches containing both B cells and persistently activated microglia.\" (Source: 42353155)\n\n\nINSTRUCTION: Study the actual abstracts provided.

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\"Does chronic latent Epstein-Barr Virus (EBV) reactivation drive microglial activation and subsequent myelin destruction in Multiple Sclerosis via the activation of the cGAS-STING innate immune pathway?\"\n\nThe provided literature supports that EBV infection is a necessary precondition for Multiple Sclerosis (MS) and that reactivation triggers inflammatory processes. There is strong mechanistic evidence linking the cGAS-STING pathway to microglial overactivation, neuroinflammation, and demyelination in MS and related models. While the literature explicitly links EBV to MS and cGAS-STING to microglial-mediated neuroinflammation and demyelination, the direct causal integration of EBV reactivation inducing microglial-mediated demyelination *specifically* through the cGAS-STING pathway in MS is strongly suggested as a potential disease-driving mechanism, though further longitudinal human data are needed to confirm the complete pathway.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific evidence suggests that Epstein-Barr virus (EBV) serves as an upstream trigger for Multiple Sclerosis (MS). Mechanistically, this process involves viral-induced reshaping of the neuroimmune environment, characterized by microglial activation and chronic neuroinflammation. The cGAS-STING axis has been identified as a critical intracellular signaling pathway driving this neuroinflammatory phenotype, leading to demyelination and neurodegeneration. \n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple Sclerosis is an immune-mediated disorder where environmental factors, most notably EBV, play a fundamental role in disease initiation. The literature establishes that \"Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development.\" Furthermore, \"When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS.\" \n\nOnce reactivated, viruses or viral components may trigger innate immune responses. In the context of MS and other neurodegenerative diseases, \"Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells.\" Activation of this pathway in microglia is a known driver of M1 polarization and neuroinflammation, as \"Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events.\" \n\nThe link to myelin damage is further solidified by the observation that \"Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens.\" Consequently, targeting this axis shows therapeutic promise, as \"From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV acts as an essential trigger for MS, and viral persistence in the CNS drives a long interval before disease manifestation.\n* The formation of Tertiary Lymphoid Structures (TLS) in the CNS during MS relapse correlates with persistent microglial activation.\n* Cross-reactivity via molecular mimicry between EBV antigens (e.g., EBNA1, LMP1) and CNS proteins (e.g., MBP, MOG) is a central etiopathogenic mechanism.\n* cGAS-STING signaling serves as a \"rheostat\" for neuroinflammation, where loss of control leads to persistent microglial M1 polarization.\n* Microglial mitochondrial dysfunction and mtDNA release are significant \"danger signals\" that activate the cGAS-STING pathway.\n* Therapeutic inhibition of the STING pathway has demonstrated efficacy in reducing neuroinflammation across multiple EAE and CNS injury models.\n* The potential use of viral platforms as engineered vectors for neuro-repair represents a paradoxical application of viruses in neurology.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"abstract_text": "ID: 41207217\nTitle: Emerging and Re-emerging viruses as triggers of human endogenous retrovirus activation: Implications for aging and age-related pathologies.\nAbstract: The human genome contains a substantial legacy of ancient retroviral infections known as Human Endogenous Retroviruses (HERVs), composing 8\u00a0% of our DNA. In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases."

By dissecting the neuronal inflammatory stress response, we discovered that neurons in MS and its mouse model induce the stimulator of interferon genes (STING). However, activation of neuronal STING requires its detachment from the stromal interaction molecule 1 (STIM1), a process triggered by glutamate excitotoxicity. This detachment initiates non-canonical STING signaling, which leads to autophagic degradation of glutathione peroxidase 4 (GPX4), essential for neuronal redox homeostasis and thereby inducing ferroptosis. Both genetic and pharmacological interventions that target STING in neurons protect against inflammation-induced neurodegeneration. Our findings position STING as a central regulator of the detrimental neuronal inflammatory stress response, integrating inflammation with glutamate signaling to cause neuronal cell death, and present it as a tractable target for treating neurodegeneration in MS."

Antimicrobial peptides (AMPs) are immunomodulatory molecules expressed in various tissues, including the CNS. Here, we investigated whether the cathelicidin-related AMP (CRAMP) modulated the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We showed that, at an early stage, CNS-recruited neutrophils produced neutrophil extracellular traps (NETs) rich in CRAMP that were required for EAE initiation. NET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response. However, at a later disease stage, neurons also expressed CRAMP that reduced EAE severity. Camp knockdown in neurons led to disease exacerbation, while local injection of CRAMP1-39 at the peak of EAE promoted disease remission. In vitro, CRAMP1-39 regulated the activation of microglia and astrocytes through the formyl peptide receptor (FPR) 2. Finally, administration of butyrate, a gut microbiota-derived metabolite, stimulated the expression of neural CRAMP via the free fatty acids receptors 2/3 (FFAR2/3), and prevented EAE. This study shows that CRAMP produced by different cell types has opposing effects on neuroinflammation, offering therapeutic opportunities for MS and other neuroinflammatory disorders."

Data on their prevalence and kinetics in low- and middle-income countries, including Morocco, remain limited. This study aimed to evaluate these infections at the Children's Hospital in Rabat. We conducted a retrospective descriptive study of pediatric patients who underwent HSCT at the Children's Hospital in Rabat from January 2018 to June 2025. Post-transplant viral monitoring included weekly quantitative PCR for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) until day 100. Targeted PCR for adenovirus, BK virus, HHV-6, and respiratory viruses was performed in symptomatic patients. Out of 33 patients, CMV was the most frequently detected agent, with an incidence of 51,5% (n\u2009=\u200917), of which 30.3% had a viral load\u2009>\u20092.5 log\u2081\u2080 IU/ml. The median time to first reactivation was 3\u2009weeks (IQR: 2-6). The vast majority of episodes occurred in seropositive (R+) recipients, mainly D+/R+. The highest viral loads were observed in patients with CMV viremia temporally associated with pulmonary involvement (2.62 log\u2081\u2080 IU/ml [IQR: 0.00-3.42]) compared to those without pulmonary involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04]; p\u2009=\u20090.007), despite the absence of virological confirmation of CMV-related pulmonary disease. Similarly, patients with gastrointestinal (GI) complications had higher viral loads (3.13 log\u2081\u2080 IU/ml [IQR: 2.23-3.89]) compared with those without GI involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04], p\u2009=\u20090.002). Concerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant. Infections were more frequent in recipients who were initially seronegative (D+/R-) included 8 of 13 patients (61.5%), No cases of post-transplant lymphoproliferative disease were reported. BK virus showed an early peak of infection between the 1st and 4th week, strongly associated with the occurrence of hemorrhagic cystitis, highlighting its significant clinical impact during this period. This study highlights the particularly early kinetics of CMV, BK virus, and EBV in our pediatric patients after HSCT, with CMV appearing around week 3, transient EBV reactivations in initially seronegative patients, and an early BK virus peak linked to hemorrhagic cystitis."

To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group) received rituximab (375 mg/m\u00b2) on day -3 before transplantation due to the presence of donor-specific antibody (MFI \u2265 2000) (n = 25) and patients in control group (C group) did not receive rituximab (n = 75) and donor-specific antibody was low (MFI < 2000). The primary objectives were the incidence of EBV-DNA viremia and PTLD within one-year post-transplantation. Secondary objectives included the incidence of CMV infection, cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic GVHD, 100-day non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS). No significant differences were observed in baseline characteristics between the two groups except for primary disease. When compared with the C group, patients in R group exhibited a lower cumulative incidence of EBV viremia within one-year post - transplantation (4.00% vs. 22.67%, P\u00a0=\u00a00.049) and a lower incidence of aGVHD (28% vs. 50.67%, P\u00a0=\u00a00.048). There was a trend toward reduction of PTLD in the R group compared with C group (0% vs. 10.67%, P\u00a0=\u00a00.089).There were no significant differences of the incidence of CMV viremia (24% vs. 13.33%, P\u00a0=\u00a00.208), cGVHD (16% vs. 12%, P\u00a0=\u00a00.607), and 100 - day NRM (4.0% vs. 10.67%, P\u00a0=\u00a00.313) between two groups.

"abstract_text": "ID: 42384430\nTitle: Viruses, Periodontitis, and Systemic Diseases.\nAbstract: Viruses are increasingly recognized as potential modulators of oral biofilm ecology and periodontal inflammation, expanding the traditional bacterial paradigm of periodontitis. Members of the Herpesviridae family, including Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus (HSV), are frequently detected in periodontal tissues and may influence disease activity through latency, reactivation, immune modulation, epithelial barrier disruption, and interactions with bacteria. These processes may contribute to local dysbiosis and sustained periodontal inflammation. The potential systemic relevance of oral viruses is biologically plausible but remains incompletely established. Viral persistence or reactivation in oral niches may contribute to systemic immune activation through hematogenous spread, saliva-mediated dissemination, aspiration, or amplification of inflammatory mediators as IL-1\u03b2, IL-6, and TNF-\u03b1. Accordingly, viruses may act as disease modifiers within the broader relationship between periodontitis and systemic conditions including cardiovascular, metabolic, respiratory, neurogenerative, pregnancy-related, and cancer-associated outcomes. However, the strength of evidence differs across these conditions. Current data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden. Nevertheless, most available evidence is observational, associative, or derived from mechanistic experimental models, and definitive proof that viruses are independent etiopathogenic drivers of periodontitis is lacking. Future longitudinal and interventional studies are needed to determine whether viral detection reflects bystander association, disease amplification, or a true pathogenic role, and whether antiviral or phage-based strategies offer clinical benefit beyond established periodontal therapy."

From a mechanistic standpoint, our previous work explained this genetic association by defining an immunomodulatory function for ataxin-1 in controlling specific genetic programs underlying B cell proliferation, activation, immunoglobulin production, and antigen presentation. Here, we employed a high-resolution multiomics analytical pipeline to further dissect the role of ataxin-1 in distinct B cell subsets upon encephalitogenic stress. By combining single-nuclei RNA-seq and ATAC-seq, along with mass-spectrometry proteomics, we documented that ataxin-1 is significantly enriched in B1 cells, marginal zone B cells, memory B cells, and precursor B cells. Pathway analysis highlighted that ataxin-1 is implicated in RNA splicing and translation processes. Conversely, no major effects were implicated for ataxin-1 in chromatin remodeling in the B cell population. Our findings expand the current knowledge of the cellular functions controlled by ataxin-1 outside of the central nervous system, and further describe a key regulator of B cell biology in health and disease."

These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation."

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

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

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

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

The provided literature corroborates that EBV is linked to MS, that microglial activation is a driver of demyelination, and that the cGAS-STING pathway mediates inflammatory responses. However, while these components are individually supported, a direct, singular, closed-loop causal mechanism linking all three stages\u2014EBV reactivation, STING-mediated microglial activation, and myelin destruction\u2014in a single patient-level longitudinal sequence remains an area of active investigation requiring further clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nMultiple sclerosis (MS) is a chronic autoimmune demyelinating disorder of the central nervous system (CNS), characterized by microglial activation and polarization as key drivers of disease pathogenesis. Growing evidence indicates that Epstein-Barr virus (EBV), a gammaherpesvirus, plays a central role in the pathogenesis of multiple sclerosis (MS). These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. \n\nPathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway. However, the exact timing and necessity of these pathways in the specific context of EBV-triggered microglial activation demand more rigorous scrutiny, as individual research components link viral persistence to primed microglial phenotypes marked by elevated MHC-II expression and heightened immune reactivity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV persistence is observed in the CNS of MS patients, but not in neurologically healthy individuals, suggesting a unique pathogenic niche.\n* Prior infection with a gammaherpesvirus sensitizes the host to a second, unrelated inflammatory stimulus, accelerating CNS demyelination.\n* The cGAS-STING pathway is both a pro-inflammatory driver in disease and a potentially protective node depending on its activation state, with down-regulation observed in some RRMS patients.\n* Neurons themselves can induce STING in response to inflammatory stress triggered by glutamate excitotoxicity, independent of microglial signaling.\n* Microglial activation in the spinal cord is often dysfunctional, characterized by ameboid morphology and delayed phagocytosis compared to the brain.\n* Ataxin-1, a gene linked to MS risk via genome-wide association studies, modulates B-cell biology and is enriched in memory and precursor B-cell subsets.\n* Viral reactivations post-transplant follow early kinetics, with BK virus associated with hemorrhagic cystitis and EBV showing transient fluctuations.\n* Berberine and similar alkaloids offer neuroprotective effects, potentially by modulating the JAK/STAT signaling pathway to reduce inflammatory demyelination.\n* Mitochondrial DNA leakage serves as an inflammatory trigger, activating cGAS-STING-mediated pyroptosis in astrocytes in epilepsy models.\n* Clinical disability progression in MS may occur independently of acute inflammatory attacks, pointing toward smouldering inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Irisin, an exercise-induced myokine, has been reported to exhibit neuroprotective effects, including anti-inflammatory activity and cognitive improvement. To investigate the therapeutic potential of irisin in the experimental autoimmune encephalomyelitis (EAE) mouse model and its effects on microglial behavior along with the underlying molecular mechanisms, we conducted the present study. Results demonstrated that irisin treatment significantly alleviated EAE severity, evidenced by reduced disease incidence, attenuated weight loss, and improved neurological scores. Histopathological analysis revealed that irisin suppressed inflammatory cell infiltration and reduced demyelination in spinal cord tissues. Furthermore, irisin inhibited microglial overactivation and promoted a phenotypic shift from the pro-inflammatory M1 to the anti-inflammatory M2 microglia. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, as indicated by downregulation of STING and phosphorylated interferon regulatory factor 3 (p-IRF3) expression. Collectively, these findings indicate that irisin alleviates neuroinflammation and exerts neuroprotective effects in EAE by modulating microglial activity through inhibition of the cGAS-STING pathway, underscoring its potential as a novel therapeutic candidate for MS.\n\nID: 41386298\nTitle: Sterile innate immune mechanisms in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by the dysfunction and death of susceptible neuronal populations. Increasing evidence has demonstrated that sustained neuroinflammation and activation of innate immune complexes underlie neurodegeneration, worsening disease progression and outcomes. Sterile inflammation (which occurs in the absence of infection) can be triggered by neurodegenerative disease-associated misfolded proteins. These studies highlight the need to decipher the complexities of innate immune signaling mechanisms and their contribution to neuropathology. In this review, we focus on major neurodegenerative diseases that have a well-documented neuroinflammatory component: Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, and frontotemporal dementia. In the context of these diseases, we discuss recent advances in innate-immune mechanisms that have been demonstrated to partake in disease progression and neurodegeneration. These include evolutionarily conserved innate-immune signaling complexes whose uncontrolled activation amplifies neurodegeneration, damaging lipid droplets that accumulate within myeloid cells and prevent their ability to clear toxic protein aggregates, as well as genome-wide studies-implicated genes/proteins. The individual and/or concerted actions of these pathways could be leveraged to rationally target the pathogenesis or progression of neurodegenerative diseases.\n\nID: 41207217\nTitle: Emerging and Re-emerging viruses as triggers of human endogenous retrovirus activation: Implications for aging and age-related pathologies.\nAbstract: The human genome contains a substantial legacy of ancient retroviral infections known as Human Endogenous Retroviruses (HERVs), composing 8\u00a0% of our DNA. In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases.\n\nID: 41063265\nTitle: Early antiviral treatment following gammaherpesvirus-68 infection of the central nervous system prevents subsequent multiple sclerosis-like disease.\nAbstract: Growing evidence indicates that Epstein-Barr virus (EBV), a gammaherpesvirus, plays a central role in the pathogenesis of multiple sclerosis (MS). The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development.\n\nID: 39656548\nTitle: Cathelicidin antimicrobial peptide expression in neutrophils and neurons antagonistically modulates neuroinflammation.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease that affects the CNS, the pathophysiology of which remains unclear and for which there is no definitive cure. Antimicrobial peptides (AMPs) are immunomodulatory molecules expressed in various tissues, including the CNS. Here, we investigated whether the cathelicidin-related AMP (CRAMP) modulated the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We showed that, at an early stage, CNS-recruited neutrophils produced neutrophil extracellular traps (NETs) rich in CRAMP that were required for EAE initiation. NET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response. However, at a later disease stage, neurons also expressed CRAMP that reduced EAE severity. Camp knockdown in neurons led to disease exacerbation, while local injection of CRAMP1-39 at the peak of EAE promoted disease remission. In vitro, CRAMP1-39 regulated the activation of microglia and astrocytes through the formyl peptide receptor (FPR) 2. Finally, administration of butyrate, a gut microbiota-derived metabolite, stimulated the expression of neural CRAMP via the free fatty acids receptors 2/3 (FFAR2/3), and prevented EAE. This study shows that CRAMP produced by different cell types has opposing effects on neuroinflammation, offering therapeutic opportunities for MS and other neuroinflammatory disorders.\n\nID: 38878778\nTitle: STING orchestrates the neuronal inflammatory stress response in multiple sclerosis.\nAbstract: Inflammation-induced neurodegeneration is a defining feature of multiple sclerosis (MS), yet the underlying mechanisms remain unclear. By dissecting the neuronal inflammatory stress response, we discovered that neurons in MS and its mouse model induce the stimulator of interferon genes (STING). However, activation of neuronal STING requires its detachment from the stromal interaction molecule 1 (STIM1), a process triggered by glutamate excitotoxicity. This detachment initiates non-canonical STING signaling, which leads to autophagic degradation of glutathione peroxidase 4 (GPX4), essential for neuronal redox homeostasis and thereby inducing ferroptosis. Both genetic and pharmacological interventions that target STING in neurons protect against inflammation-induced neurodegeneration. Our findings position STING as a central regulator of the detrimental neuronal inflammatory stress response, integrating inflammation with glutamate signaling to cause neuronal cell death, and present it as a tractable target for treating neurodegeneration in MS.\n\nID: 33948692\nTitle: Multiple sclerosis is linked to MAPKERK overactivity in microglia.\nAbstract: Reassessment of published observations in patients with multiple sclerosis (MS) suggests a microglial malfunction due to inappropriate (over)activity of the mitogen-activated protein kinase pathway ERK (MAPKERK). These observations regard biochemistry as well as epigenetics, and all indicate involvement of this pathway. Recent preclinical research on neurodegeneration already pointed towards a role of MAPK pathways, in particular MAPKERK. This is important as microglia with overactive MAPK have been identified to disturb local oligodendrocytes which can lead to locoregional demyelination, hallmark of MS. This constitutes a new concept on pathophysiology of MS, besides the prevailing view, i.e., autoimmunity. Acknowledged risk factors for MS, such as EBV infection, hypovitaminosis D, and smoking, all downregulate MAPKERK negative feedback phosphatases that normally regulate MAPKERK activity. Consequently, these factors may contribute to inappropriate MAPKERK overactivity, and thereby to neurodegeneration. Also, MAPKERK overactivity in microglia, as a factor in the pathophysiology of MS, could explain ongoing neurodegeneration in MS patients despite optimized immunosuppressive or immunomodulatory treatment. Currently, for these patients with progressive disease, no effective treatment exists. In such refractory MS, targeting the cause of overactive MAPKERK in microglia merits further investigation as this phenomenon may imply a novel treatment approach.\n\nID: 33291536\nTitle: The STING-IFN-\u03b2-Dependent Axis Is Markedly Low in Patients with Relapsing-Remitting Multiple Sclerosis.\nAbstract: Cyclic GMP-AMP-synthase is a sensor of endogenous nucleic acids, which subsequently elicits a stimulator of interferon genes (STING)-dependent type I interferon (IFN) response defending us against viruses and other intracellular pathogens. This pathway can drive pathological inflammation, as documented for type I interferonopathies. In contrast, specific STING activation and subsequent IFN-\u03b2 release have shown beneficial effects on experimental autoimmune encephalomyelitis (EAE) as a model for multiple sclerosis (MS). Although less severe cases of relapse-remitting MS (RRMS) are treated with IFN-\u03b2, there is little information correlating aberrant type I IFN signaling and the pathologic conditions of MS. We hypothesized that there is a link between STING activation and the endogenous production of IFN-\u03b2 during neuroinflammation. Gene expression analysis in EAE mice showed that Sting level decreased in the peripheral lymphoid tissue, while its level increased within the central nervous system over the course of the disease. Similar patterns could be verified in peripheral immune cells during the acute phases of RRMS in comparison to remitting phases and appropriately matched healthy controls. Our study is the first to provide evidence that the STING/IFN-\u03b2-axis is downregulated in RRMS patients, meriting further intensified research to understand its role in the pathophysiology of MS and potential translational applications.\n\nID: 26190523\nTitle: Natalizumab modulates the humoral response against HERV-Wenv73-88 in a follow-up study of Multiple Sclerosis patients.\nAbstract: Multiple Sclerosis (MS) is a heterogeneous disorder of the central nervous system (CNS) that begins as an inflammatory autoimmune disorder mediated by auto-reactive lymphocyte followed by microglial activation and chronic degeneration. The etiology of Multiple Sclerosis (MS) is unknown but several data support the hypothesis of possible infectious agents which may act as a trigger for the pathogenic cascade. Human endogenous retrovirus (HERV-W/MSRV), Epstein Barr Virus (EBV) and Mycobacterium avium ss. paratuberculosis (MAP) have been associated to Multiple Sclerosis. In this study, we evaluated the humoral response against different peptides: the human endogenous retrovirus HERV-Wenv73-88, MAP106c121-132 from MAP, EBNA1 400-413 from EBV and the homologous human peptide MBP85-98 in a cohort of MS patients treated with natalizumab. Results showed a statistically significant difference in the response against the HERV-W peptide in MS patients after two years of natalizumab treatment.\n\nID: 42404903\nTitle: Cholinergic regulation of neuroinflammation: linking microglia, immunometabolism, and neuromodulation.\nAbstract: Neuroinflammation is increasingly recognized as a core pathological process in various neurological diseases, including neurodegenerative disorders, stroke, autoimmune demyelinating diseases, and acute brain dysfunction associated with systemic inflammation. Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention.\n\nID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\n\nID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17\u202fA+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.\n\nID: 42401006\nTitle: Spinal cord microglia exhibit a dysfunctional response to myelin damage.\nAbstract: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that affects both the brain and spinal cord, although the brain has historically received greater attention. In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair.\n\nID: 42400090\nTitle: Study protocol: double-blind, randomized, prospective, placebo controlled parallel group phase II study to investigate the effect of glycerol phenylbutyrate (GPB) on neurofilament light chain (NfL) levels in patients with corticobasal syndrome (CBS).\nAbstract: Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disorder, with no disease-modifying treatments currently available. The most common underlying pathology is a 4-repeat tauopathy. Neurofilament light chain (NfL) is a biomarker of neuronal damage and has shown potential as a measure of disease progression. Glycerol phenylbutyrate (GPB), a prodrug of phenylbutyric acid, has demonstrated potential neuroprotective properties in preclinical studies on tauopathies. This phase II clinical trial will investigate the effects of GPB on NfL levels in CBS patients. The primary objective is to assess the efficacy of GPB in reducing NfL levels over 26\u00a0weeks compared to placebo as well as safety and tolerability of GPB. Secondary objectives include evaluating changes in clinical scales. This is an investigator-initiated double-blind, randomized, placebo-controlled, parallel-group phase II clinical trial, performed in two German university hospitals. A total of 32 patients with CBS will be enrolled and randomized to receive either GPB or placebo. The primary outcome is the change in NfL levels between baseline and 26\u00a0weeks as well as safety and tolerability of GPB. Secondary outcomes are changes in clinical scores. Exploratory analyses involve pharmacokinetics, changes in the metabolomic, proteomic and lipidomic profiles and imaging outcomes, such as MRI and microglia-PET. The study protocol has been approved by the lead ethics committee at LMU Munich and conforms to the ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines. If successful, this clinical trial could identify a novel therapeutic approach for slowing disease progression in CBS, contributing to a broader understanding of GPB's therapeutic potential. The clinical trial has been registered in ClinicalTrials.gov (NCT05983588) and due to Transition in the Clinical Trials Information System (CTIS; EUCT No. 2024-516897-31-00, date of transition: 2024-09-26).\n\nID: 42399983\nTitle: Regional mapping of CSF1R-positive microglia in neurodegenerative diseases and progressive MS, with exploratory presynaptic marker analyses.\nAbstract: Microglial colony-stimulating factor-1 receptor (CSF1R) is a therapeutic and imaging target, yet the regional, disease-specific distribution of CSF1R-positive microglia in the human brain remains incompletely defined, limiting interpretation of emerging CSF1R-PET signals. We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers. A cross\u2011disease, region\u2011resolved map reveals region\u2011specific changes in CSF1R\u2009+\u2009cell density in neurodegeneration, but only white matter in MS. These findings provide the histological context needed to interpret future CSF1R\u2011PET. Prospective studies pairing CSF1R\u2011PET with SV2A\u2011PET and multiplex tissue profiling are warranted to define microglial states and synaptic outcomes in vivo.\n\nID: 42398656\nTitle: Ethyl acetate extract of Poecilobdella manillensis Lesson ameliorates ischemia stroke through inhibiting cell apoptosis and suppressing TLR4/NF-\u03baB-mediates neuroinflammation.\nAbstract: Poecilobdella manillensis Lesson is a well-recognized medicinal leech in traditional Chinese medicine and Guangxi Zhuang ethnic medicine. It has long been used to activate blood circulation and remove blood stasis for the treatment of ischemic stroke. Modern pharmacological research has verified its potent anticoagulant and anti-inflammatory activities. Current studies mainly focus on its polypeptide components that exert antithrombotic effects to improve cerebral ischemia, while the neuroprotective potential and related mechanisms of its small-molecule constituents remain largely unclear. This study aimed to investigate the therapeutic effects of the ethyl acetate extract (EA) of P. manillensis on cerebral ischemia-reperfusion injury and to clarify its underlying molecular mechanism. The chemical constituents of EA were identified by UPLC-Q-TOF-MS/MS. Network pharmacology and molecular docking were used to predict and verify core targets and pathways. Neuroprotective and anti-inflammatory effects of EA were evaluated in a rat MCAO/R model, OGD/R-injured SH-SY5Y cells, and LPS-stimulated BV2 cells, using histological staining, Western blot, immunohistochemistry, and RT-qPCR. Seven small-molecule components were identified in EA, and 314 overlapping targets related to ischemic stroke were screened. Network analysis showed that TLR4 was the core target, and the main enriched pathways included NF-\u03baB, Toll-like receptor, apoptosis and TNF signaling pathways. Consistent with the predicted results, EA significantly reduced cerebral infarct volume and improved neurological deficits in MCAO/R rats, and inhibited neuronal apoptosis and microglial inflammation in vivo. In vitro, EA notably improved the survival of OGD/R-injured neurons and suppressed LPS-induced inflammatory responses in BV2 cells. Meanwhile, EA markedly downregulated the expression of TLR4/NF-\u03baB and NLRP3 inflammasome-related molecules. The present study demonstrated that EA protects against cerebral ischemia-reperfusion injury by inhibiting neuronal apoptosis and TLR4/NF-\u03baB-mediated neuroinflammation. These findings provide a scientific basis for the traditional clinical application of P. manillensis and suggest that EA could serve as a potential therapeutic candidate for ischemic stroke.\n\nID: 42397694\nTitle: Border-Associated Macrophages in CNS Health and Disease: A Comprehensive Review of Ontogeny, Heterogeneity, and Functional Plasticity at Neural Interfaces.\nAbstract: Border-associated macrophages (BAMs) represent a specialized population of tissue-resident immune cells strategically positioned at the critical interfaces between the central nervous system (CNS) and peripheral circulation, including the meninges, choroid plexus, and perivascular spaces. As frontline sentinels of the neuroimmune system, BAMs perform essential functions in immune surveillance, barrier integrity maintenance, and homeostatic regulation, yet their unique biology and disease-associated roles remain incompletely characterized compared to parenchymal microglia. This review aims to synthesize current knowledge on BAM ontogenetic origins, compartment-specific heterogeneity, transcriptional programs, and functional outputs in both health and neurological disorders. We conducted a comprehensive literature analysis integrating findings from lineage tracing studies, single-cell RNA sequencing, spatial transcriptomics, and functional interrogation in animal models of disease. The results reveal that BAMs exhibit remarkable cellular diversity shaped by distinct ontogenetic origins-primarily yolk sac-derived erythro-myeloid progenitors with variable contributions from fetal liver and postnatal monocytes depending on anatomical compartment. Compartment-specific marker combinations (CD206, LYVE1, CD163, MHCII) define functionally distinct subsets, and core transcriptional regulators including PU.1 and IRF8 maintain BAM identity while CSF-1/IL-34-CSF1R signaling governs survival and renewal. In neurological disorders including ischemic stroke, Alzheimer's disease, multiple sclerosis, and brain tumors, BAMs display pronounced double-edged roles, transitioning from protective homeostatic guardians to pathogenic drivers depending on disease stage and microenvironmental context. This comprehensive analysis establishes a unified framework for understanding BAM biology and identifies critical opportunities for developing subset-specific therapeutic strategies targeting these interface macrophages in neurological diseases.\n\nID: 42395866\nTitle: The role of SUMOylation in regulating proteins that drive neuronal disease progression.\nAbstract: SUMOylation is a post-translational modification in which a Small Ubiquitin-like Modifier (SUMO) protein is reversibly attached to a lysine residue on a target protein in an ATP-dependent process. This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders.\n\nID: 42395216\nTitle: Human Exposure to Micro- and Nanoplastics and Their Potential Neurological Implications: A Systematic Review of Emerging Evidence.\nAbstract: The growing prevalence of micro- and nanoplastics (MNPs) in the environment elicits concerns about their possible impact on human neurological health. Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42393898\nTitle: Heterocyclic Scaffolds as Therapeutic Agents in Multiple Sclerosis: Mechanisms and SAR Study.\nAbstract: Multiple sclerosis (MS) is a progressive, immune-mediated condition characterized by the destruction of myelin, the protective insulation surrounding nerve fibers. This ongoing assault triggers a cascade of damage, including persistent inflammatory responses, loss of myelinproducing oligodendrocytes, axonal degradation, and cumulative neurological impairment. While motor and sensory difficulties are hallmark features, patients frequently contend with less visible but equally debilitating symptoms such as cognitive dysfunction, profound fatigue, affective disorders, nerve pain, and autonomic instability. These often-overlooked manifestations critically impact well-being and functional capacity. The pathophysiology of MS is increasingly understood as a network of overlapping cellular and molecular dysfunctions. Alongside irregularities in the endocannabinoid signaling network, key contributors include aberrant immune communication, persistently activated microglia, impaired mitochondrial energy production, and dysregulated activity of enzymes like PDE7, MAGL, ROCK, and PADs. These interconnected pathways collectively drive disease initiation and advancement. This analysis synthesizes established information on current FDA-approved treatments for MS and examines promising novel small-molecule compounds aimed at specific disease-relevant targets. A significant focus is placed on medicinal chemistry advancements, particularly the design and optimization of heterocyclic compounds. Scaffolds incorporating quinolines, pyrimidines, indoles, and related nitrogen-containing structures demonstrate considerable potential for conferring immunomodulation, reducing inflammation, and protecting neural tissue. By evaluating structure-activity relationships, binding mechanisms, and strategic drug design, this review offers an integrated perspective to inform the creation of new, targeted therapies for MS.\n\nID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.\n\nID: 42392745\nTitle: [Investigation of antidepressant active components and mechanisms of total triterpenoids of Wolfiporia cocos based on serum pharmacochemistry combined with network pharmacology and experimental validation].\nAbstract: Based on the total triterpenoids of Wolfiporia cocos(TTWC) in the serum of depressed rats, this study combined network pharmacology, molecular docking, and experimental validation to explore the antidepressant active components and mechanisms of TTWC. Firstly, ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was used to identify the blood-entering components of TTWC. Then, network pharmacology and molecular docking were used to predict the potential antidepressant active components and mechanisms of TTWC. Finally, an in vitro model constructed using lipopolysaccharide(LPS)-treated BV2 cells was used to validate the main active components. A total of 38 triterpenoid components of W. cocos were detected in the blood. Thirty potential active components were obtained through screening by network pharmacology, and 122 component-disease overlapping targets were obtained, which showed that interleukin(IL)-6, tumor necrosis factor(TNF), Albumin(ALB), non-receptor tyrosine kinase(SRC), and IL-1\u03b2 might be the core targets. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment results indicated that the antidepressant effect of TTWC might be influenced by neuroactive ligand-receptor interaction signaling pathway, Fc \u03b5 RI signaling pathway, TNF signaling pathway, and mitogen-activated protein kinase(MAPK) signaling pathway. The molecular docking results showed that the potential antidepressant active components of TTWC had a good binding effect with the core targets. The results of cell assays showed that TTWC and nine components, including pachymic acid and pachymic acid A, reduced the secretion levels of tumor necrosis factor-\u03b1(TNF-\u03b1), IL-6, IL-1\u03b2, IL-18, and nitric oxide(NO) to varying degrees and down-regulated the protein expression levels of phosphorylated p38 mitogen-activated protein kinase(p-p38) and phosphorylated c-Jun amino-terminal protein kinase(p-JNK). Comparison of the results of the experiments in each group showed that there were differences in the potency and main targets of the components. On the basis of previous studies, the present study explored the antidepressant active components of TTWC and demonstrated that they can effectively reduce the secretion of inflammatory factors and inflammatory mediators, and realize the control of neuroinflammation through the regulation of the MAPK pathway. The results of this study showed that TTWC inhibited neuroinflammation in a multi-component, multi-target, and multi-pathway manner, thus realizing the antidepressant effect.\n\nID: 42392741\nTitle: [Dihydroartemisinin ameliorates inflammation in experimental autoimmune encephalomyelitis by enhancing AXL signaling in microglia].\nAbstract: This study aimed to investigate the mechanism of dihydroartemisinin(DHA) in ameliorating multiple sclerosis(MS). Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.\n\nID: 42391630\nTitle: Helicobacter pylori infection and neurological disorders: association, mechanisms, and clinical implications.\nAbstract: Helicobacter pylori infects nearly half of the global population and has traditionally been viewed as a pathogen restricted to the gastric mucosa. Growing evidence, however, suggests that chronic infection may exert systemic effects extending to the central nervous system. This review critically examines the potential neurological implications of H.\u00a0pylori infection within the emerging framework of the gut-brain axis. We performed a narrative, hypothesis-generating review of human observational and interventional studies complemented by mechanistic experimental research. The literature was evaluated with particular attention to study design, heterogeneity, and potential confounding in reported associations between H.\u00a0pylori infection and neurological disorders. Across multiple studies, H.\u00a0pylori infection has been linked to a modestly increased prevalence of Parkinson's disease and dementia, although findings remain heterogeneous. In Parkinson's disease, infection may exacerbate motor fluctuations and reduce levodopa bioavailability, with partial clinical improvement reported following eradication in selected patients. Experimental studies further demonstrate that bacterial outer membrane vesicles can access the brain and promote neuroinflammatory and amyloidogenic processes, supporting biological plausibility. By contrast, several epidemiological studies report an inverse association with multiple sclerosis, suggesting potential immunomodulatory effects. Evidence relating H.\u00a0pylori to migraine and mood disorders remains inconsistent. Current data do not support H.\u00a0pylori as a primary cause of neurological disease. Instead, the infection may act as a context-dependent modifier within the complex inflammatory and immunometabolic networks of the gut-brain axis. Clarifying this relationship will require prospective studies integrating microbial strain profiling, biomarker-defined neurological phenotypes, and adequately powered interventional trials.\n\nID: 42391599\nTitle: Factors Associated With Disability Improvement and Worsening Independent of Attacks in Patients With AQP4-IgG+ NMOSD and MOGAD: A Multicenter Cohort Study.\nAbstract: Disability trajectories in aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorder (AQP4-IgG+ NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are primarily driven by attack-related damage. Confirmed disability worsening (CDW) independent of attacks has been described but occurs infrequently in AQP4-IgG+ NMOSD and MOGAD. Confirmed disability improvement (CDI) has not been evaluated in large cohorts. We determined the frequency of CDI and CDW independent of attacks and identified clinical factors associated with these outcomes in AQP4-IgG+ NMOSD and MOGAD. This retrospective, multicenter cohort study analyzed data from the German Neuromyelitis Optica Study Group (NEMOS) registry. Adult patients with AQP4-IgG+ NMOSD or MOGAD and longitudinal Expanded Disability Status Scale (EDSS) assessments were included. EDSS episodes were defined as periods with \u22653 EDSS assessments without attacks, obtained \u226590 days after attack. CDW and CDI were defined as sustained EDSS increase or decrease (\u22651.5 for baseline EDSS 0; \u22651.0 for EDSS 1.0-5.5; \u22650.5 for EDSS \u22656.0) confirmed after at least 6 months. The primary outcomes were annualized CDI and CDW rates. Risk factors were assessed using multivariable Anderson-Gill regression models. A total of 338 EDSS episodes of 307 patients (n: 202/105, median age at EDSS change: 56/41 years, 88/49% female, both p < 0.001; AQP4-IgG+ NMOSD/MOGAD) were included. Adjusted annualized CDI and CDW rates did not differ between AQP4-IgG+ NMOSD (CDI: 0.083, 95% CI 0.029-0.233; CDW: 0.025, 95% CI 0.007-0.092) and MOGAD (CDI: 0.057, 95% CI 0.012-0.277; CDW: 0.036, 95% CI 0.002-0.513). In AQP4-IgG+ NMOSD, a lower number of prior attacks was associated with higher CDI rates (hazard ratio [HR] 0.89, 95% CI 0.82-0.97). Younger age was associated with increased CDI rates in both AQP4-IgG+ NMOSD and MOGAD (HR 0.96, 95% CI 0.94-0.99, for both). CDI and CDW independent of attacks, although rare, occur in AQP4-IgG+ NMOSD and MOGAD. The association between fewer prior attacks and higher CDI rates in AQP4-IgG+ NMOSD underscores the importance of early attack prevention. Limitations include the retrospective design, and the limited number of CDI and CDW events.\n\nID: 42390760\nTitle: The dual role of mTOR in multiple sclerosis pathophysiology: a systematic review.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disease characterized by demyelination, neuroinflammation, and progressive neurodegeneration. The mechanistic target of rapamycin (mTOR) pathway plays a key role in regulating immune responses, cell metabolism, autophagy, and repair processes. Although the role of mTOR in neurodegeneration has been explored in previous reviews, a systematic assessment of its function in MS across different models is still lacking. This systematic review aimed to examine the role of mTOR signaling in the pathophysiology of MS. Following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, we screened preclinical and clinical studies using two databases and assessed the risk of bias specific to the study types. A total of 189 records were identified, of which 90 met the\u00a0inclusion criteria for qualitative analysis. Studies using in vitro and in vivo (mainly rodent models, both sexes) models of MS, as well as MS patient tissue or data, consistently demonstrated that mTOR is involved in the MS-related processes neuroinflammation, myelination, autophagy, gliosis, mitochondrial dysfunction, and oxidative stress. mTOR inhibition reduces pro-inflammatory signaling and may enhance autophagy, offering neuroprotection. In contrast, activation of mTOR promotes remyelination by enhancing oligodendrocyte differentiation and maturation. These remyelinating effects may be masked in inflammatory environments, because activation of mTOR supports immune cell expansion and glial reactivity, inducing inflammation and oxidative stress. Overall, our findings underscore a dual role of mTOR in MS pathology, with important implications for disease stage and timing of intervention. Although mTOR is mechanistically important in MS, its therapeutic modulation is unlikely to be readily clinically translatable without a substantial risk of unintended and context-dependent effects.\n\nID: 42390621\nTitle: Supra-additive neuroprotective effects of berberine-metformin combination in diabetic encephalopathy: Chou-Talalay synergy quantification, AMPK-Nrf2 axis modulation, and pharmacokinetic verification.\nAbstract: Type 2 diabetes mellitus (T2DM) increases the risk of hippocampal neurodegeneration and cognitive decline. Berberine and metformin independently activate AMPK and may engage Nrf2-mediated antioxidant defenses, yet their combined neuroprotective interaction has not been formally quantified using validated synergy frameworks, nor has its pharmacokinetic basis been verified. Streptozotocin-nicotinamide diabetic rats were allocated to twelve groups (n\u2009=\u200913/group) receiving berberine (50, 100, 150\u00a0mg/kg/day) or metformin (100, 200, 300\u00a0mg/kg/day) monotherapy, fixed-ratio 1:2 combinations, or vehicle controls (including a non-diabetic combination group) orally for six weeks. The novel object recognition (NOR) discrimination index served as the predefined primary endpoint for Chou-Talalay combination index (CI) analysis. Hippocampal mechanistic (n\u2009=\u20096/group) and satellite LC-MS/MS pharmacokinetic (n\u2009=\u20096/group) analyses were performed. Diabetes impaired NOR discrimination index (37.2\u2009\u00b1\u20093.8% vs. 68.4\u2009\u00b1\u20093.2%; p\u2009<\u20090.001). The reference combination (100\u2009+\u2009200\u00a0mg/kg) restored NOR to 67.1\u2009\u00b1\u20093.6% with CI\u2009=\u20090.65 (95% CI: 0.43-0.91), synergism maintained across the full effect range. All six neuroinflammatory endpoints achieved Benjamini-Hochberg-corrected significance (p_adj\u2009=\u20090.006-0.043; Tier 2). Non-diabetic combination animals showed reduced AMPK activation magnitude (1.53 vs. 2.31-fold; P_adj\u2009=\u20090.067; Tier 3, hypothesis-generating). LC-MS/MS verified bioequivalent drug exposure. Berberine-metformin co-treatment is associated with CI-quantified supra-additive recognition memory recovery in diabetic encephalopathy, with neuroinflammatory suppression as the most statistically robust mechanistic correlate. Pharmacokinetic findings are consistent with a pharmacodynamic rather than pharmacokinetic basis. Causal involvement of the AMPK-Nrf2 axis remains correlative pending direct loss-of-function validation.\n\nID: 42390174\nTitle: Proteomic Profiling of Optic Nerves From SMOX-Deficient Mice Identifies Regulators of Neuroinflammation and Axonal Damage in Optic Neuritis.\nAbstract: Visual dysfunction due to optic neuritis (ON) is an early clinical manifestation of multiple sclerosis (MS). ON is characterized by inflammation of the optic nerve, demyelination, axonal damage, and retinal ganglion cell (RGC) loss. Previously, we showed that spermine oxidase (SMOX), a polyamine catabolizing enzyme, modulates visual function in an experimental model of ON. Using proteomic analysis, the present study aimed to identify SMOX-regulated molecular pathways involved in ON-associated visual dysfunction. Experimental autoimmune encephalomyelitis (EAE) was induced in wild-type (WT) and SMOX-deficient (Smox KO) mice. Clinical scoring of mice was recorded daily. Optic nerves from WT and Smox KO EAE mice and their controls were collected and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pathway enrichment and comparative analyses were performed to identify key processes and pathways regulated by SMOX. Immunofluorescence was performed to detect changes in the expression of key proteins. Smox KO EAE mice showed delayed and reduced clinical scores. Pathway enrichment analysis identified several key processes affected in EAE, including regulation of the actin cytoskeleton, tight junction integrity, and platelet activation/aggregation. The comparative analysis of the WT EAE and Smox KO EAE proteomes, together with false discovery rate (FDR)-corrected pathway enrichment analysis, indicated attenuation of neuroinflammatory pathways in the SMOX-deficient optic nerve. Furthermore, SMOX deficiency restored key cytoskeletal and cellular-adhesion proteins essential for neuronal integrity. Immunofluorescence studies confirmed dysregulation of receptor for activated C kinase 1 (RACK1), actinin alpha 4 (ACTN4), high mobility group box 1 (HMGB1), and S100 calcium-binding protein B (S100B), critical proteins involved in immune signaling, cytoskeletal stability, and inflammation. These findings indicate the impact of SMOX on inflammation and cytoskeletal stabilization in ON and its potential as a therapeutic target in preserving vision in MS.\n\nID: 42388566\nTitle: Insights from LC-MS-based cerebrospinal fluid metabolomics in tuberculous meningitis.\nAbstract: Tuberculous meningitis (TBM) remains the most devastating form of extra-pulmonary tuberculosis (TB) and is associated with high mortality and neurological deficits, often due to delayed diagnosis. Disease outcome in TBM depends critically on early diagnosis and timely initiation of treatment. However, the non-specific clinical presentation of TBM poses a major diagnostic challenge, as no single test can reliably establish a definitive diagnosis. The recommended diagnostic approach, GeneXpert MTB/RIF ultra, combined with mycobacterial culture of cerebrospinal fluid (CSF), remains limited by suboptimal sensitivity and restricted availability in many resource-constrained settings. These limitations underscore the urgent need for novel biomarkers that reflect TBM-specific pathophysiology and enable a single rapid, reliable, and accessible diagnosis. This perspective paper draws on insights from LC-MS-based CSF metabolomic profiling to highlight metabolic alterations in TBM. Key metabolic pathways-fatty acid \u03b2-oxidation reflected by altered acylcarnitine profiles, amino acid perturbations, and the tryptophan-kynurenine pathway-are discussed in relation to cellular energy disruption and neuroinflammation. Based on these alterations, free carnitine and quinolinic acid emerge as priority candidates for further investigation. Free carnitine reflects TBM-associated energy dysregulation, while quinolinic acid appears to mirror the severity of neuroinflammation. Future studies should focus on validating these metabolites in independent cohorts and on assessing their translational potential in more readily accessible biofluids, with the ultimate goal of enabling simplified, widely implemented diagnostic assays.\n\nID: 42387307\nTitle: Baseline Neuroinflammation Stratifies TSPO-PET Response to Disease-Modifying Therapy in Multiple Sclerosis.\nAbstract: To investigate which baseline clinical and imaging characteristics best predict TSPO-PET-measurable reduction in glial activation following treatment of multiple sclerosis (MS), to utilize this information for designing more efficient biomarker-based clinical trials targeting glial activation. This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS.\n\nID: 42386214\nTitle: Anti-Ma2 encephalitis: when the examination localises beyond MRI.\nAbstract: \n\nID: 42383392\nTitle: Role of Toll-like receptors and oral-gut-brain axis in neurodegenerative and neuropsychiatric disorders.\nAbstract: The oral-gut-brain axis is a path connecting the gastrointestinal tract and the central nervous system (CNS). The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders. Because the contributing factors have not been fully understood yet, further studies could help provide novel therapeutic opportunities.\n\nID: 42383100\nTitle: T Helper Cells and Cytokine Networks in the Immunopathogenesis of Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder of CNS with demyelination, neurodegeneration and compartmentalized inflammatory disorder. Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta. The review also explores the cytokine network biomarkers, CSF and serum signatures and single-cell immune states, as well as existing and new drugs. These include migration blockade, targeting of S1P-receptors, anti-CD20 therapy, targeting of Th17/GM-CSF and JAK-STAT pathways, low-dose IL-2, approaches of targeting antigens and engineered Tregs. Investigating the areas of stage and compartment-specific CD4+ T-cell circuits can help to advance targeted immunomodulation in progressive MS and neuro-repair.\n\nID: 42382783\nTitle: HLA-DRB1*15:01 drives sex- and age-dependent microglial immune phenotypes and neuroimmune signaling.\nAbstract: The major histocompatibility complex class II (MHC-II) pathway is central to adaptive immunity and immune tolerance, and its age-related dysregulation is increasingly linked to chronic neuroinflammation. The HLA-DRB1*15:01 allele, the strongest genetic risk factor for multiple sclerosis, has been implicated in shaping pathogenic CD4+ T-cell responses and broader neuroimmune vulnerability, yet how this allele modulates age- and sex-dependent neuroimmune processes within the central nervous system (CNS) remains poorly defined. We investigated the impact of HLA-DRB1*15:01 expression using a humanized mouse model (HLA mice) and wild-type (WT) controls. Male and female mice were analyzed at 6, 9, and 15 months of age, with endocrine stratification in females. Behavioral testing, flow cytometry, immunofluorescence, and multiplex cytokine analyses were used to assess cognitive performance, glial immune-associated changes and oxidative stress, astrocyte-microglia IL-3/IL-3R signaling, endothelial activation, selective immune cell accumulation at CNS borders, tissue organization, and hippocampal cytokine profiles. HLA mice developed age- and sex-dependent cognitive impairment, most pronounced in aged females. HLA-DRB1*15:01 expression promoted progressive microglial immune-associated changes, characterized by increased CD14 and CD68 expression, elevated mitochondrial oxidative stress, altered astrocyte phenotypes, and enhanced IL-3/IL-3R signaling. Hippocampal axonal and myelin organization was disrupted in aged HLA mice and was spatially associated with increased microglial presence. HLA mice also exhibited selective immune remodeling, including increased accumulation of CD4+ T cells and NK1.1+CD3+ natural killer T (NKT) cells, particularly in females, accompanied by endothelial activation marked by elevated ICAM-1 and E-selectin expression. Hippocampal cytokine profiling revealed selective sex-biased alterations, without broad induction of classical inflammatory cytokines. Together, these findings demonstrate that HLA-DRB1*15:01 drives a coordinated, age- and sex-dependent neuroinflammatory program linking behavioral dysfunction, glial immune-associated changes and oxidative stress, selective immune cell recruitment, endothelial activation, tissue remodeling, and targeted cytokine imbalance. This integrated phenotype provides mechanistic insight into how this major MS risk allele confers vulnerability to chronic neuroinflammation during aging, with heightened impact in females, independent of reproductive cycling stage.\n\nID: 42377966\nTitle: Blood cytotoxic natural killer-like CD8 + CD94+ T cells migrate to the brain and predict multiple sclerosis severity.\nAbstract: Memory CD8+ T cells are central to multiple sclerosis (MS) and undergo clonal expansion, but disease-associated states remain incompletely defined. By single-cell profiling of circulating memory CD8+ T cells from patients with relapsing-remitting MS, healthy volunteers, and neuroinflammatory controls, we identified an MS-associated cytotoxic subset with NK-like features. These cells increase around relapse activity and belong to an oligoclonal reservoir. In an independent cohort sampled at the first clinical event, an elevated frequency of NK-like CD8+ T cells predicted an aggressive MS course two years later and was associated with a migratory/inflammatory program. Bulk and single-cell RNA-seq confirmed the NK-like transcriptional signature, and functional assays demonstrated TCR-independent cytotoxicity. Immunostaining and spatial transcriptomics revealed enrichment of these cells in MS lesions and a spatial association with macrophages/microglia. Together, our results identify a cytotoxic NK-like CD8+ T-cell subset that links peripheral inflammation to CNS lesions and may serve as an early biomarker of MS severity.\n\nID: 42377674\nTitle: Effects of vanillic acid and exercise on early-life stress-induced anxiety-, depression-like behaviors and neuronal damage in rats.\nAbstract: Early-life stress has been closely linked to the development of various neuropsychiatric disorders, including anxiety and depression. This study investigated the protective effects of vanillic acid, exercise, and their combination on early-life stress-induced anxiety- and depression-like behaviors and neuronal damage in the maternal separation (MS) rat model. Pups from Wistar albino rats were subjected to a maternal separation protocol, whereas control pups were not. After the MS protocol, rats were randomly divided into four groups: saline, exercise, vanillic acid (VA; 100\u00a0mg/kg, oral), or a combination group. Before decapitation, behavioral tests were conducted, and tissue samples were collected for assessments. Compared with the MS group, vanillic acid reduced corticosterone levels and anxiety- and depression-like behaviors (p\u2009<\u20090.05\u2009-\u20090.001). Compared with the MS group, oxidative damage (malondialdehyde, glutathione, myeloperoxidase), apoptotic parameters (B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax)), neuronal damage, neuroinflammation (TNF-\u03b1, IL-6), and BDNF activity were reversed in all groups (p\u2009<\u20090.01\u2009-\u20090.001). Nuclear factor-\u03baB (NF-\u03baB) was suppressed in the VA and exercise groups compared with the MS group (p\u2009<\u20090.001), whereas no difference was observed in the combined group. These findings suggest that vanillic acid or exercise may offer a promising strategy for mitigating the harmful neurological consequences of early-life psychological stress.\n\nID: 42377668\nTitle: Near\u2011Infrared Photobiomodulation in White\u2011Matter Disease: From Microglial States to Measurable Endpoints.\nAbstract: White-matter (WM) injury contributes to disability across multiple sclerosis, traumatic brain injury, Alzheimer's disease and related dementias, and small-vessel disease. We use microglial state programs as an organizing axis for WM injury-to-repair logic, while emphasizing that WM outcomes are multicellular and involve oligodendrocyte-lineage cells, astrocytes, axons/neurons, and vascular factors. Microglia span an injury-repair continuum, from inflammatory programs that increase oxidative stress and debris burden to repair-competent programs that support debris handling, remyelination, and axonal integrity. Near-infrared photobiomodulation (PBM; ~800-1100\u00a0nm) is most consistently associated with modulation of mitochondrial redox/bioenergetic pathways and inflammatory tone. CCO-centered mechanistic framing is best established near ~\u2009800-850\u00a0nm, whereas longer wavelengths (e.g., ~\u20091064-1070\u00a0nm) may involve additional initiating mechanisms with downstream convergence on shared redox/bioenergetic and inflammatory pathways. Across demyelination and spinal cord injury models, appropriately dosed PBM has been reported to reduce inflammatory glial readouts and to associate with improved myelin/axon-related endpoints and functional measures, although mechanistic certainty varies across models. Human evidence remains early but broadly supports safety; a randomized trial in moderate traumatic brain injury reported treatment-related changes in diffusion-MRI WM metrics, while small dementia and chronic-injury studies report heterogeneous cognitive and physiological signals. Given dose dependence and depth-limited transcranial delivery, we synthesize mechanism-informed, dose-aware reporting guidance and WM-anchored outcome frameworks that pair diffusion MRI/DTI with interpretable biomarkers (e.g., NfL, GFAP, sTREM2) and thermally controlled sham designs. We also note potential indirect/systemic contributions that could help reconcile depth-dose constraints with deeper WM effects.\n\nID: 42376811\nTitle: Longitudinal magnetic resonance spectroscopy study of metabolite changes over 2\u2009years in relapsing and primary progressive multiple sclerosis treated with ocrelizumab.\nAbstract: Magnetic resonance spectroscopy (MRS) offers non-invasive assessments of neuron-oligodendrocyte coupling and neuroinflammation to monitor treatment response in multiple sclerosis (MS). To track changes in N-acetylaspartate and myo-inositol in relapsing MS (RMS) and primary progressive MS (PPMS) patients treated with ocrelizumab over 2\u2009years. Single-voxel MRS at 3T was acquired at baseline in 10 healthy controls (HCs), and weeks 0, 12, 24, 52, and 96 in MS participants at a single center. Baseline myo-inositol was higher in PPMS than RMS (p\u2009=\u20090.047) and HC (p\u2009=\u20090.001), and correlated with disability across both MS groups (r\u2009=\u20090.57, p\u2009=\u20090.0006). Following treatment with ocrelizumab, both RMS and PPMS demonstrated declines in myo-inositol over time, returning toward HC levels (RMS p\u2009=\u20090.016; PPMS p\u2009=\u20090.004). Conversely, N-acetylaspartate was not different between groups and remained stable over time. Ocrelizumab treatment is associated with declining myo-inositol levels measured by MRS in both RMS and PPMS. Myo-inositol offers a unique biomarker to track resolution of gliosis and reactive microglia with treatment. Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

The understanding of the pathogenesis is still limited. Key factors such as neuroinflammation, neurovascular dysfunction, and disruption of cellular energy metabolism have been identified. There are no evidence-based treatments targeting the pathologic mechanisms of cognitive impairment associated with PCS available to date. Thus, treatment is directed towards symptom relief. EGb 761\u00ae, a dry extract from the leaves of Ginkgo biloba has anti-neuroinflammatory properties, improves microcirculation and neuronal mitochondrial function. Clinical efficacy in the treatment of cognitive impairment has been demonstrated. It is therefore reasonable to assume that the extract might be beneficial for use in cognitive impairment associated with PCS. Case series of patients with PCS reported significant improvement in cognitive function within 6\u202fmonths of treatment. The EGb 761\u00ae Post COVID Cognitive Impairment Study (EGb COCOS) aims to establish whether EGb 761\u00ae is an effective treatment for cognitive impairment in PCS. In this prospective, multicentre, randomised, placebo-controlled, triple-blind trial, treatment effects and safety of EGb 761\u00ae in patients with cognitive impairment associated with PCS will be investigated. Eligible patients aged \u226518\u202fyears with a history of probable or confirmed SARS-CoV-2 infection, diagnosis of PCS with cognitive symptoms that have been present for at least 2\u202fmonths, objective cognitive impairment, and mild-to-moderate anxiety or depressive symptoms will be enrolled. Participants (n\u202f=\u202f400 planned) will be randomised to oral, 12-week treatment with EGb 761\u00ae (240\u202fmg) or matching placebo once daily. The effect of EGb 761\u00ae will be assessed on cognitive, neuropsychiatric, neurosensory, and functional outcomes. The analysis will be exploratory in nature, since generally accepted and validated primary endpoints have not been established. For safety, the incidence of adverse events (AEs) and serious AEs will be recorded. The results of this trial will show for the first time whether EGb 761\u00ae is an effective treatment for cognitive impairment in PCS. https://euclinicaltrials.eu/ctis-public/view/2024-517199-39-00?lang=en, Identifier CTIS2024-517199-39-00.\n\nID: 42373953\nTitle: Moving artificial intelligence from research to real-world clinical use in neurology.\nAbstract: Artificial intelligence (AI) applications in neurology have reached an inflection point. Despite US Food and Drug Administration approval of numerous algorithms in neuroimaging, neurophysiology, genetics and chatbots, their real-world impact remains limited. This disconnect between research promise and clinical reality represents a gap in understanding how to translate AI algorithms into clinical benefit for patients globally. In this Perspective, we examine the challenges that prevent clinical AI use in neurology moving beyond pilot studies towards meaningful clinical impact. We consider the steps required in the process of translation, including research, validation of AI models, regulatory approval pathways and clinical implementation. We discuss implementation of AI models as stand-alone products versus embedded platforms, and the requirements for sustainable deployment. Beyond traditional clinical decision support tools, we examine paraclinical applications of AI, including chatbots and ambient voice documentation. We recommend expanding capacity for prospective validation and scaling by implementing and validating technologies across multiple sites and countries, which requires infrastructure from long-term partnerships. Neurology must shift from asking whether AI can work to understanding how to use it safely at scale.\n\nID: 42370935\nTitle: Chronic hyperinsulinemia accelerates adipose senescence via mitochondrial dysfunction and cGAS-STING signalling.\nAbstract: Prediabetes and Type 2 Diabetes represent major global health challenges and have escalated to pandemic levels. Adipose tissue functions as a critical endocrine organ, playing a central role in maintaining glucose homeostasis during fasting, feeding, and stress responses. In this study, we demonstrated that prolonged chronic hyperinsulinemic stress increases the burden of senescent adipocytes, accompanied by activation of the cGAS-STING signalling pathway. Chronic hyperinsulinemia-induced insulin-resistant 3T3-L1 and human mesenchymal stem cell-derived adipocytes exhibited elevated senescence-associated phenotypes, mitochondrial dysfunction and impaired cellular energetics. Notably, we found that mitochondrial DNA leakage triggered the cGAS-STING pathway in insulin-resistant adipocytes and mouse models. Temporal analysis revealed that mitochondrial dysfunction was detectable at earlier stages of chronic insulin exposure, preceding activation of the cGAS-STING pathway and senescence-associated markers, supporting a progressive model of cellular dysfunction. This phenomenon was also observed in adipose depots of individuals with Type 2 diabetes, underscoring the translational relevance of our findings. Targeting cGAS or STING, either pharmacologically or through genetic silencing, significantly reduced inflammatory and senescence-related features in hyperinsulinemia-induced insulin-resistant 3T3-L1 adipocytes. Furthermore, attenuation of senescence treatment with the combination of Dasatinib and Quercetin alleviated mitochondrial stress and associated adipose dysfunction. Collectively, our findings support a model in which prolonged hyperinsulinemic stress induces early mitochondrial dysfunction, followed by activation of cGAS-STING signalling and the subsequent emergence of adipocyte senescence-associated phenotypes, contributing to adipose tissue dysfunction in insulin resistance and Type 2 Diabetes.\n\nID: 42370465\nTitle: Evaluating the effectiveness of simvastatin in slowing the progression of disability in secondary progressive multiple sclerosis: a synopsis of MS-STAT2, a multicentre, randomised controlled, double-blind, phase 3 clinical trial.\nAbstract: Despite the relative success of immuno-modulatory disease-modifying therapy in relapsing remitting multiple sclerosis, progressive worsening of disability remains a major problem, particularly for those with secondary progressive multiple sclerosis. Various underlying mechanisms are likely to contribute, augmented by comorbidities (such as vascular risk) and ageing. In the phase 2b MS-STAT trial, simvastatin (80\u2005mg) (Sandoz Ltd, Camberley, UK) reduced the mean annualised whole brain atrophy rate by 43% compared to placebo in patients with secondary progressive multiple sclerosis (p\u2005=\u20050.003). We now report the phase 3, MS-STAT2 trial, with confirmed progression of disability as the primary outcome. A multicentre, phase 3, randomised, double-blind, placebo-controlled clinical trial was conducted at 31 UK neuroscience centres and district general hospitals. Secondary progressive multiple sclerosis participants aged 18-65 years were randomised 1\u2005:\u20051 to oral simvastatin (80\u2005mg), or matched placebo, based on a minimisation algorithm that incorporated the following factors: sex (male/female); age (< or \u2265\u200545 years); Expanded Disability Status Scale baseline score (\u2264\u20055.5 or \u2265\u20056); whether participants were taking newly licensed (2017 onward) disease-modifying treatments for secondary progressive multiple sclerosis; and trial site. An independent and secure online randomisation service was used. All participants, site investigators and the trial co-ordinating team were blinded to treatment allocation. The Expanded Disability Status Scale was measured every 6 months and was compared to baseline scores, with remote data collection used when enforced by the COVID-19 pandemic. The primary outcome was time to Expanded Disability Status Scale-confirmed disability progression. Progression of disability was defined as an increase of at least one point on the Expanded Disability Status Scale if the baseline score was <\u20056, or an increase of 0.5 point if the baseline score was \u2265\u20056. The initial disability progression event was finalised as confirmed if the increase in Expanded Disability Status Scale score persisted at the next assessments \u2265\u20056 months later. Follow-up was for 36 months, or 54 months, for those without confirmed disability progression at 36 months who agreed to enter an optional blinded extension. An intention-to-treat analysis was carried out. The study was conducted between 10 May 2018 and 26 July 2024. There were 964 participants randomised, with 482 in the placebo group and 482 in the simvastatin group. 173 (35.9%) participants in the placebo group and 192 (39.8%) participants in the simvastatin group experienced Expanded Disability Status Scale-confirmed disability progression (adjusted hazard ratio =\u20051.13, 95% confidence interval 0.91 to 1.39, p\u2005=\u20050.263). No material differences in the secondary outcomes were observed. No major safety issues were seen. The MS-STAT2 trial did not demonstrate a treatment effect of simvastatin in slowing disability progression in participants with secondary progressive multiple sclerosis. Despite the favourable outcomes of the previous phase 2b trial, simvastatin use in secondary progressive multiple sclerosis should be confined to existing vascular indications. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 15/57/143. Multiple sclerosis is a lifelong condition that affects the brain and spinal cord. Many people with multiple sclerosis start with a type called relapsing-remitting multiple sclerosis, which can later become secondary progressive multiple sclerosis. Secondary progressive multiple sclerosis causes steady worsening of disability over time, and currently, there are very few treatment options for people without signs of active inflammation. Simvastatin is a cholesterol-lowering drug (a statin) that is widely used for heart disease. Earlier research (the Simvastatin in Secondary Progressive Multiple Sclerosis phase 2 trial) suggested that high-dose simvastatin might slow brain shrinkage and disability in people with secondary progressive multiple sclerosis. To test this further, researchers ran a large phase 3 clinical trial called Simvastatin in Secondary Progressive Multiple Sclerosis (phase 3 trial), involving 964 participants across the United Kingdom. Half were given simvastatin and half a placebo, and they were followed up while continuing to take these for 3 years. For participants whose disability was stable at 3 years, they could continue in the trial on the same medication for up to 4.5 years if they were happy to do so. The main aim was to see if simvastatin could slow down worsening disability, which was measured using a scale called Expanded Disability Status Scale. The Expanded Disability Status Scale data were mainly collected at face-to-face appointments, but some assessments were conducted by telephone when enforced by the COVID-19 pandemic. The results showed no significant difference between the simvastatin and placebo groups. Simvastatin did not delay disability progression. The trial also looked at other outcomes such as walking speed, hand function, memory and quality of life. Again, there were no meaningful differences. Importantly, simvastatin was generally safe, and side effects were rare. The trial also found that people with higher disability levels faced higher personal and financial costs, and many relied on unpaid care from family or friends. Overall, the Simvastatin in Secondary Progressive Multiple Sclerosis phase 3 trial provides clear evidence that simvastatin does not have a therapeutic effect in slowing disability progression in people with secondary progressive multiple sclerosis. It also offers valuable insights for future research into progressive multiple sclerosis and highlights the need for new treatments that target the disease\u2019s underlying causes.\n\nID: 42368585\nTitle: Ginsenoside Rg1 alleviates post-ischemic stroke neuroinflammation by inhibiting CKLF1-mediated suppression of dead/dying neuron clearance.\nAbstract: The reduction of dead/dying neurons represents a critical mechanism for the anti-acute ischemic stroke (AIS) effect of Panax notoginseng, however, its molecular basis remains unclear. Recent findings implicate chemokine-like factor 1 (CKLF1) as a key contributor to the impaired clearance of dying neurons. Here, we established an integrated high-throughput screening strategy combining biolayer interferometry (BLI), liquid chromatography-tandem mass spectrometry (LC-MS/MS), and NanoBRET technologies to identify CKLF1 inhibitors among Panax notoginseng saponins (PNS). Of note, ginsenoside Rg1 (GRg1) exhibits the highest affinity for CKLF1 and the most potent inhibitory efficacy against the CKLF1-CCR4 interaction, effectively suppressing CKLF1-C27 peptide-induced calcium influx and cytokine production. In experimental AIS models, GRg1 confers neuroprotective properties by mitigating ischemic brain damage and promoting neuronal functional recovery. Mechanistically, GRg1 binds to CKLF1 and modulates the mTORC1/TFEB pathway, enhancing lysosomal function and thereby facilitating the clearance of dead/dying neurons. This study presents an efficient approach for the discovery of natural CKLF1 inhibitors and highlights GRg1 as a promising therapeutic candidate for enhancing the clearance of dead/dying neurons in AIS.\n\nID: 42367807\nTitle: Modulation of the immunological and neuroinflammatory microenvironment in older people with multiple sclerosis.\nAbstract: Life expectancy and the age at onset of multiple sclerosis (MS) are increasing, and a growing proportion of people with MS (pwMS) are now older than 55-60 years. Aging modifies MS pathobiology, with the dominant disease mechanisms moving from focal, relapse-driven inflammation to chronic, compartmentalized neuroinflammation and neurodegeneration. In this narrative review, we summarize current knowledge on the relationship between brain aging and MS, integrating clinical, radiological, pathological and therapeutic evidence. We first discuss mechanisms of immunosenescence and \"inflammaging\", including changes in adaptive and innate immunity, gut microbiota dysbiosis, mitochondrial dysfunction and blood-brain barrier dysfunction, and how these processes favor microglial activation, slowly expanding lesions, smouldering MS and progression independent of relapse activity. We then examine the impact of age on disability trajectories, cognitive decline and comorbidities, and the role of vascular and neurodegenerative mechanisms. The review also addresses age-related changes in safety and efficacy of disease-modifying therapies (DMT), with a focus on high-efficacy DMT, de-escalation and discontinuation strategies, and the management of infections, malignancies and polypharmacy in older pwMS. Finally, we describe new approaches relevant to this population, including Bruton's tyrosine kinase inhibitors, neuroprotective and remyelinating agents, advanced cellular therapies and lifestyle-based interventions. We conclude by outlining practical implications for personalized treatment decisions in older pwMS and open questions that future clinical trials and biomarker studies must address.\n\nID: 42365629\nTitle: Current perspectives on the pathogenesis of multiple sclerosis: A minireview.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disease of the central nervous system characterized by inflammation, reactive gliosis, and progressive neuroaxonal damage resulting in heterogeneous clinical and histopathological manifestations. As MS often leads to disability at a young age, it represents a substantial socio-economic burden in developed countries. The etiopathogenesis of MS is multifactorial and incompletely understood, involving genetic, immunologic, and environmental factors. Recent research highlights immune responses to Epstein-Barr virus, blood-brain barrier disruption, microbiome-gut-brain axis alterations, oxidative damage, and mitochondrial dysfunction. Studying patients with newly diagnosed MS without significant comorbidities provides insight into early disease mechanisms before disability development or long-term treatment effects. This mini-review focuses on early vascular and metabolic alterations that may contribute to MS, including lipoprotein subfractions as markers of incipient atherosclerosis, endothelial dysfunction as an initiating vascular event, and autonomic nervous system imbalance during disease progression. It also addresses insulin sensitivity as a key metabolic factor alongside chronic inflammation and oxidative damage as interconnected mechanisms driving tissue injury. Metabolic changes reflecting neuronal impairment, mitochondrial dysfunction, and astroglial activation are detectable in both lesional and normal-appearing white matter in early stages. Reduced antioxidant capacity supports a role of oxidative damage in MS pathogenesis. Accelerated vascular aging, independent of traditional cardiovascular risk factors, may progress from endothelial dysfunction to structural atherosclerotic changes. Subtle alterations in lipoprotein profiles further suggest an increased risk of atherosclerosis, potentially influenced by inflammatory activity and oxidative damage, with possible sex-specific differences. Autonomic dysfunction appears to develop secondary to disease progression rather than as a primary driver of pathogenesis.\n\nID: 42364895\nTitle: Early prediabetes aggravates neuroinflammatory and cognitive dysfunctional responses to chlorpyrifos exposure: Possible amelioration by arachidonic acid.\nAbstract: Chronic exposure to organophosphorus pesticides (OPs) is increasingly implicated in neuroinflammatory and cognitive disorders, yet susceptibility factors and pharmacological modulators remain poorly defined. Given the global rise in metabolic dysfunction, this study investigated whether prediabetes amplifies the neurotoxic impact of chronic chlorpyrifos (CPF) exposure and examined arachidonic acid (AA) as a potential modulator of the associated detrimental phenotype, with emphasis on endocannabinoid system (ECS) perturbation. Male Sprague-Dawley rats were rendered prediabetic and dermally exposed to CPF for 35 days, in the absence or presence of oral AA supplementation (3\u202fmg/kg/day). Chronic CPF exposure induced systemic metabolic dysfunction, cerebrovascular hypoperfusion, adipose inflammation, and marked neuroinflammation accompanied by cognitive and motor impairment, as assessed by behavioral testing, laser speckle imaging, biochemical assays, histopathology, immunohistochemistry, and LC-MS/MS. These effects were exacerbated in prediabetic rats. CPF accumulated preferentially in adipose depots and brain tissue and was associated with elevated IL-1\u03b2 and oxidative stress. Molecularly, CPF disrupted ECS homeostasis, with increased hippocampal 2-arachidonoylglycerol levels, downregulation of CB1 receptors, and upregulation of CB2 receptors, consistent with a stress-induced but functionally impaired endocannabinoid response. AA supplementation significantly mitigated CPF- and prediabetes-induced dysfunctional phenotype, and rebalanced ECS signaling. Collectively, these findings identify early prediabetes as a critical vulnerability state that aggravates OP neurotoxicity and demonstrate that AA exerts broad neuroprotective and metabolic benefits, in part through modulation of endocannabinoid and inflammatory signaling. This work highlights the ECS-adipose-brain axis as a pharmacologically relevant interface linking environmental toxicant exposure to metabolic and neurocognitive decline.\n\nID: 42364023\nTitle: Neurotherapeutic roles of the protective arm of the renin-angiotensin system: from inflammation to cognitive rescue.\nAbstract: The renin-angiotensin system (RAS), traditionally recognized for its role in regulating blood pressure and fluid homeostasis, is increasingly understood to exert important effects across multiple organ systems, including the central nervous system (CNS). A local brain RAS contributes to neurovascular regulation, inflammation, oxidative stress, synaptic plasticity, and cognitive function. This review critically summarizes the neurotherapeutic relevance of the protective RAS arm, particularly the angiotensin-converting enzyme 2 (ACE2)-angiotensin-(1-7)-Mas receptor axis, the angiotensin II type 2 receptor (AT2R), and the alamandine/Mas-related G protein-coupled receptor D (MrgD) pathway. Experimental evidence suggests that these pathways may counterbalance angiotensin II type 1 receptor signaling by reducing neuroinflammation, oxidative injury, vascular dysfunction, and neuronal loss in models of ischemic stroke, Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The strongest evidence remains preclinical, with most data derived from cell culture and animal models, whereas human evidence is still indirect and largely based on observational or early translational studies of RAS-modifying drugs. Important uncertainties remain regarding blood-brain barrier penetration, receptor-specific signaling, disease-stage dependency, systemic vascular effects, and reproducibility across models. Therefore, protective RAS signaling should be considered a promising but still exploratory therapeutic framework rather than an established treatment strategy for neurological disease. Future work should prioritize selective brain-penetrant agonists, validated biomarkers of central RAS activity, and rigorously designed clinical trials to determine whether modulation of ACE2-angiotensin-(1-7)-Mas, AT2R, or alamandine/MrgD signaling can produce clinically meaningful neuroprotection.\n\nID: 42406761\nTitle: Allogeneic HSCT For Pediatric Extranodal NK/T-Cell Lymphoma Transformed From Chronic Active Epstein-Barr Virus Infection: A Case Report.\nAbstract: This study aimed to explore the clinical characteristics, diagnostic criteria, therapeutic regimens, and prognostic features of pediatric extranodal natural killer/T-cell lymphoma (ENKTL) transformed from chronic active Epstein-Barr virus infection (CAEBV), to provide evidence-based references for standardized clinical diagnosis and treatment of these refractory diseases. A pediatric patient with CAEBV-transformed ENKTL admitted to Nanshan Hospital Affiliated to Shenzhen University was retrospectively enrolled in this study, who received allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patient achieved complete remission after multiple cycles of preoperative chemotherapy. Triple probiotic preparations containing Bifidobacterium, Bacillus licheniformis, and Lactobacillus were administered throughout the preconditioning phase and post-transplant period. Persistent complete remission was achieved after transplantation with full donor chimerism of 100%. Long-term follow-up over 1 year post-transplantation showed no disease recurrence, EBV reactivation, severe infectious complications, or acute and chronic transplantation-related complications. This case study confirmed that allo-HSCT is safe and effective for the treatment of pediatric CAEBV-transformed ENKTL, with a significantly superior long-term prognosis compared with chemotherapy alone. Peri-transplant adjuvant application of microecological preparations may reduce the risks of respiratory tract infection and graft-versus-host disease in children. Given that this is a single-case study with limited follow-up duration, there are certain limitations in the clinical generalization of the conclusions.\n\nID: 42404888\nTitle: The application of rituximab during the conditioning regimen prevents Epstein - Barr virus infection following rATG-based haploidentical hematopoietic stem cell transplantation in the era of letermovir for cytomegalovirus prophylaxis.\nAbstract: In the era of letermovir for cytomegalovirus (CMV) prophylaxis, several centers reported that the incidence of Epstein-Barr virus (EBV) infection were significantly increased. To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group) received rituximab (375 mg/m\u00b2) on day -3 before transplantation due to the presence of donor-specific antibody (MFI \u2265 2000) (n = 25) and patients in control group (C group) did not receive rituximab (n = 75) and donor-specific antibody was low (MFI < 2000). The primary objectives were the incidence of EBV-DNA viremia and PTLD within one-year post-transplantation. Secondary objectives included the incidence of CMV infection, cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic GVHD, 100-day non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS). No significant differences were observed in baseline characteristics between the two groups except for primary disease. When compared with the C group, patients in R group exhibited a lower cumulative incidence of EBV viremia within one-year post - transplantation (4.00% vs. 22.67%, P\u00a0=\u00a00.049) and a lower incidence of aGVHD (28% vs. 50.67%, P\u00a0=\u00a00.048). There was a trend toward reduction of PTLD in the R group compared with C group (0% vs. 10.67%, P\u00a0=\u00a00.089).There were no significant differences of the incidence of CMV viremia (24% vs. 13.33%, P\u00a0=\u00a00.208), cGVHD (16% vs. 12%, P\u00a0=\u00a00.607), and 100 - day NRM (4.0% vs. 10.67%, P\u00a0=\u00a00.313) between two groups. The 2-year OS rates in the R group and C group were 83.8% \u00b1 0.086% and 81.9% \u00b1 0.050% respectively (P\u00a0=\u00a00.360). The 2-year PFS rates in the R group and C group were 83.8% \u00b1 0.086% and 72.6% \u00b1 0.068% respectively (P\u00a0=\u00a00.360). The combined use of rituximab during the conditioning regimen may be regarded as an effective strategy for preventing EBV reactivation after rATG - based haplo - HSCT in the era of letermovir for CMV prophylaxis.Prospective randomized controlled trials are still required to further validate the reliability of the results.\n\nID: 42404887\nTitle: Mechanisms and impact of long COVID: pathophysiology, neuropsychiatric effects and vaccination.\nAbstract: Long COVID or post-acute sequelae of COVID-19 is defined as an after-effect of acute COVID-19 infection. Its broad clinical symptoms include brain fog, shortness of breath, fatigue, joint, chest, or muscle pain, dysautonomia and neuropsychiatric symptoms such as anxiety, depression and post-traumatic stress disorder. It is estimated that 1 in every 5 COVID-19 survivors exhibit symptoms within the Long COVID bracket. An array of risk factors such as smoking habit, age, obesity, female sex, and prior hospitalization may increase the probability of a person developing Long COVID. While the underlying mechanisms of Long COVID remain elusive, we examine the various possible pathophysiologies involved in Long COVID. We take up impactful neuropsychiatric issues as another spectrum of Long COVID symptoms and the likely effect of various forms of COVID-19 vaccines. In this review, the focus will be on the main mechanisms associated with the development of long COVID, which include latent Epstein-Barr virus reactivation, molecular mimicry, virus persistence, autoantibodies, and mitochondrial dysfunction. Understanding these mechanisms shed light on the continued persistence of COVID-19 related symptoms long after the resolution of acute infection. For instance, the reactivation of Epstein-Barr virus in the immunocompromised context seen post-acute SARS-CoV-2 infection could lead to the symptoms commonly observed in Long COVID such as fatigue and brain fog. The Epstein-Barr virus could possibly disrupt mitochondrial function, explaining the fatigue commonly observed in Long COVID patients. Other factors such as continued presence of viral particles in specific areas such as the gut may result in continued inflammation, leading to manifestations such as fatigue, cognitive impairment and gastrointestinal dysfunction. Additionally, heightened and persistent presence of autoantibodies post-acute infection results in persistent symptoms and could potentially trigger the onset of autoimmune disorders. We also aim to revisit the diverse and prolonged effects of the COVID-19 pandemic that continue to affect the well-being and quality of human life.\n\nID: 42401247\nTitle: Panax quinquefolius saponins promote remyelination via orchestrating HMGCS1-NPC1-MAL-mediated lipid metabolism and rebalancing JAK-STAT signaling in a cuprizone-induced demyelination model.\nAbstract: Panax quinquefolius L. is traditionally used as a \"Qi-tonifying and Yin-nourishing\" herb for weakness and limb flaccidity, symptoms described as \"Feng fei\" or flaccidity syndrome. These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.\n\nID: 42400702\nTitle: The Potential of Rehabilitation to Amplify Experience-Induced Myelin Plasticity and Remyelination in Multiple Sclerosis: A Narrative Review.\nAbstract: This narrative review synthesizes emerging evidence on experience-dependent myelin plasticity and its relevance for neurorehabilitation in persons with multiple sclerosis (MS). Building on foundational work demonstrating motor learning-induced neuroplasticity, we highlight growing recognition that myelination remains adaptable across the lifespan and may be harnessed to support motor relearning, neuroprotection, and remyelination in MS. Preclinical and human studies demonstrate that neuronal activity, especially that induced by motor learning, regulates oligodendrocyte behavior and myelin remodeling. Rodent models show that skilled training enhances oligodendrocyte precursor cell proliferation and myelin thickness, while human neuroimaging confirms training-related increases in myelin-sensitive metrics within task-relevant systems. In MS, early evidence from exercise and motor training studies suggests task-specific white matter plasticity, though sample sizes remain small and imaging outcomes heterogeneous. Additional work points to synergistic potential between behavioral training, neuromodulation, and pharmacologic remyelinating agents. Notably, the combination of exercise and clemastine produces robust remyelination in preclinical models. With MS patients now living longer, aging introduces additional vulnerabilities-including inflammation, microglial dysfunction, and reduced regenerative capacity-but myelin retains responsiveness to behavioral and environmental enrichment. Experience-dependent myelin plasticity represents a promising but underexplored mechanism for enhancing neurorehabilitation outcomes. Motor learning, physical exercise, and multimodal interventions may support adaptive myelination, though optimized dosing, timing, and biomarkers remain undefined. Future research should employ targeted, multimodal imaging approaches and integrate behavioral, neuromodulatory, and pharmacologic strategies, in addition to following patients longitudinally post-intervention, to clarify the therapeutic potential of activity-driven remyelination.\n\nID: 42398276\nTitle: Rising burden and future projections of multiple sclerosis in East Asia: Findings from the global burden of disease study 2021.\nAbstract: Multiple sclerosis (MS) is a chronic central nervous system disorder characterized by immune-mediated inflammation and demyelination. Although East Asia was historically regarded as a low-prevalence region, recent evidence suggests a rising MS burden, yet region-wide analyses of long-term trends and future projections remain limited. Using data from the Global Burden of Disease (GBD) 2021 study, we assessed MS burden in China, Japan, South Korea, North Korea, and Mongolia from 1990 to 2021. Age-standardized prevalence (ASPR), incidence (ASIR), mortality (ASMR), and disability-adjusted life years (DALYs) were analyzed, with temporal trends quantified using estimated annual percentage change (EAPC) and future burdens projected to 2041 through autoregressive integrated moving average (ARIMA) models. Between 1990 and 2021, ASPR in East Asia steadily increased, while ASDR declined. Mongolia consistently carried the highest burden, whereas China experienced the fastest growth, with ASPR projected to rise by more than 80% by 2041. Japan and South Korea showed relatively stable patterns, while North Korea exhibited moderate increases. Across all countries, females consistently bore higher burdens than men, and MS indicators were positively correlated with the Sociodemographic Index (SDI). Overall, the burden of MS in East Asia is increasing, with China projected to experience the steepest rise by 2041 and Mongolia continuing to carry a disproportionately high load. This study integrates long-term trends, cross-country comparisons, and gender-specific analyses to evaluate the burden of MS in East Asia, providing relevant evidence for formulating region-specific and gender-sensitive policies, enhancing preparedness, and strengthening health systems in East Asia to respond to the increasing burden of multiple sclerosis.\n\nID: 42396568\nTitle: Extranodal Nasal Type NK/T-Cell Lymphoma of the Transverse Colon With Gastrointestinal Perforation in a 15-Year-Old: Durable Remission With Modified SMILE Chemotherapy and HSCT.\nAbstract: NK/T-cell lymphoma (NKTCL) is an aggressive lymphoma associated with Epstein-Barr virus (EBV), with higher incidence in Asian populations. Typically, patients present in their fifth decade with extranodal disease in the upper aerodigestive tract. Pediatric NKTCL is rare, with no established pediatric standard of care treatment. We describe the case of a healthy 15-year-old Filipino-Canadian male who presented with transverse colon perforation and was diagnosed with extranodal EBV\u2009+\u2009nasal type NKTCL of the gastrointestinal (GI) tract. After a complicated initial surgical course, we elected to treat him using six cycles of modified SMILE (dexamethasone, PEG-asparaginase, ifosfamide, and etoposide) chemotherapy and consolidative hematopoietic stem cell transplant (HSCT). The post-HSCT course involved cytomegalovirus reactivation (buccal lesions, viremia); adenovirus reactivation (positive nasal swab, viremia); zoster reactivation; acute and chronic oral/upper GI graft-versus-host disease (GVHD); chronic skin GVHD (vitiligo); and avascular necrosis. At the most recent follow-up, surveillance imaging and investigations at 2\u2009years post-transplant showed durable CR1 and 100% donor chimerism. To our knowledge, this is the fourth reported case of primary GI NKTCL in a pediatric/adolescent patient; the only patient treated with an asparaginase-containing regimen; and the only patient to undergo consolidative HSCT. Our patient's outcome supports the utilization of an aggressive approach to treat GI NKTCL in young, fit patients similar to Stage III/VI nasal NKTCL. Our case also highlights unique treatment considerations for adolescent cancer patients, including delayed diagnoses and lack of standardized protocols.\n\nID: 42394357\nTitle: Characterizing Combined Central and Peripheral Demyelination-Insights From a Multimodal Comparison With Chronic Inflammatory Demyelinating Polyneuropathy and Multiple Sclerosis.\nAbstract: Combined central and peripheral demyelination (CCPD) is a rare dysimmune disorder sharing features with multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Direct comparisons of central and peripheral diagnostic findings across these entities remain limited. We, therefore, performed a systematic study assessing nervous system involvement in CCPD, using magnetic resonance imaging (MRI), nerve ultrasound (US), and nerve conduction study (NCS) and compared findings to MS and CIDP controls. We conducted a descriptive case study including 4 CCPD patients, 13 CIDP patients, and 10 MS controls. All subjects underwent a standardized protocol of NCS and US. In addition, MS and CCPD patients also underwent brain and spinal cord MRI. Cerebrospinal fluid testing was performed in 20/27 patients. NCS revealed electrodiagnostic features suggestive of demyelination in all CCPD and CIDP patients, fulfilling the electrodiagnostic criteria for CIDP. We found motor conduction abnormalities in two MS patients, not fulfilling criteria for demyelination. US showed a similar pattern of multifocal nerve enlargement in CCPD and CIDP patients, while three MS patients also demonstrated mild proximal median nerve enlargement. Finally, CSF oligoclonal bands were only found in MS patients. Peripheral diagnostic tools reveal strikingly similar electrophysiological and morphologic features in CCPD and CIDP, underscoring a potential overlap in their disease mechanisms and the challenges of distinguishing these entities based on peripheral nerve assessment alone. Our findings further suggest that US could serve as a potentially useful screening tool in patients with predominantly central nervous system demyelinating syndromes and suspected peripheral involvement, helping to guide subsequent electrophysiological testing.\n\nID: 42391237\nTitle: DMS-informed secondary structure modeling of Epstein-Barr Virus LMP-1 pre-mRNA defines novel elements spanning introns.\nAbstract: The Epstein-Barr virus (EBV) infects over 95% of adults, establishing lifelong latency and contributing to the development of various malignancies, including Burkitt lymphoma and nasopharyngeal carcinoma. However, the RNA structures regulating the splicing of the critical EBV gene, latent membrane protein 1 (LMP1), remain uncharacterized. To identify these regulatory elements, we applied spliceosome inhibition with RNA probing and sequencing (SIRP-seq) to the BJAB-B1 cell line. By utilizing the spliceosome inhibitor pladienolide B, we enriched pre-mRNA species, enabling the detection of structural features within both the full-length pre-mRNA (LMP1-FL) and an alternatively spliced isoform retaining intron 2 (LMP1-AS). The resulting chemical probing datasets informed the RNA folding algorithms RNAfold and ScanFold to generate the first high-resolution secondary structure models for the LMP1 pre-mRNA, encompassing both exonic and intronic regions. Our results identify 11 novel, thermodynamically stable RNA structures, with several key elements positioned near splice junctions. Notably, three structures (Structures 8, 9, and 10) were identified near the 3' splice site of intron 2, appearing in alternative conformations that may influence splicing accessibility. Furthermore, these structures map to regions containing disease-relevant mutations associated with patient survival in Burkitt lymphoma. This structural framework provides new insights into how LMP1 splicing may be regulated by RNA structure and identifies potential novel therapeutic targets for mitigating EBV-associated diseases.\n\nID: 42390217\nTitle: Multiomics Profiling During Autoimmune Demyelination Highlights a Complex Regulatory Role for Ataxin-1 in B Cells.\nAbstract: Recent evidence from genome-wide association studies has linked the ataxin-1 gene (ATXN1) to an increased risk of developing the autoimmune demyelinating disorder multiple sclerosis. From a mechanistic standpoint, our previous work explained this genetic association by defining an immunomodulatory function for ataxin-1 in controlling specific genetic programs underlying B cell proliferation, activation, immunoglobulin production, and antigen presentation. Here, we employed a high-resolution multiomics analytical pipeline to further dissect the role of ataxin-1 in distinct B cell subsets upon encephalitogenic stress. By combining single-nuclei RNA-seq and ATAC-seq, along with mass-spectrometry proteomics, we documented that ataxin-1 is significantly enriched in B1 cells, marginal zone B cells, memory B cells, and precursor B cells. Pathway analysis highlighted that ataxin-1 is implicated in RNA splicing and translation processes. Conversely, no major effects were implicated for ataxin-1 in chromatin remodeling in the B cell population. Our findings expand the current knowledge of the cellular functions controlled by ataxin-1 outside of the central nervous system, and further describe a key regulator of B cell biology in health and disease.\n\nID: 42389513\nTitle: Epstein-Barr virus-driven immunosuppression in nasopharyngeal carcinoma: a comprehensive review of viral mechanisms, spatial tumor ecosystems, and precision therapeutics.\nAbstract: EBV infection is the defining etiological factor in nasopharyngeal carcinoma (NPC), yet how viral factors systematically remodel the tumor immune microenvironment (TME) to sustain immunosuppression remains incompletely characterized. Existing reviews lack an integrated synthesis of viral mechanisms, TME spatial architecture, and therapeutic translation. We conducted a comprehensive literature search across PubMed, Embase, and Web of Science from inception to December 2025, with an update check to May 2026, following PRISMA guidelines. Given the broad scope, a narrative synthesis was adopted rather than a formal systematic review. Two reviewers independently screened 4,235 records, and 182 studies were included. Methodological quality was assessed using Cochrane RoB 2 and Newcastle-Ottawa tools, with detailed risk-of-bias summaries provided in the Supplementary Materials. EBV establishes hierarchical immunosuppression in NPC. Latent proteins LMP1, LMP2A, and EBNA1, together with non-coding RNAs (BART miRNAs, EBERs), constitutively activate NF-\u03baB, PI3K/AKT/mTOR, and JAK/STAT pathways; LMP1 further promotes exosomal secretion and metabolic reprogramming that expands myeloid-derived suppressor cells. Lytic-phase genetic polymorphisms in BALF2, BZLF1, and BRLF1 are associated with differential immune signatures, though these associations remain correlative and lack functional validation. Based on limited spatial profiling studies, the TME can be provisionally conceptualized as five distinct immunosuppressive niches-immune-excluded fibrotic stroma, immunosuppressive interface, tertiary lymphoid structures, vascular niches, and hypoxic tumor cores. Anti-PD-1-based chemo-immunotherapy achieves 20-91% objective response rates and is now the first-line standard for recurrent/metastatic disease, as established by the JUPITER-02 and RATIONALE-309 trials. EBV-directed adoptive cell therapies, therapeutic vaccines, lytic induction, and stromal modulators have shown early promise, although definitive efficacy data are still lacking. Biomarker integration-including plasma EBV DNA, viral genetic variants, spatial omics, and liquid biopsy-offers potential for patient stratification, yet most emerging markers remain investigational. This comprehensive review provides an evidence-based framework linking EBV latent and lytic mechanisms to TME remodeling and precision therapeutics. Key limitations include over-reliance on descriptive studies and insufficient functional validation of viral polymorphisms. Future research should prioritize spatial multi-omics, isogenic viral systems, humanized models, and adaptive trial designs to advance mechanism-driven therapy. https://www.crd.york.ac.uk/PROSPERO/, identifier CRD420261421334.\n\nID: 42389315\nTitle: Clinical presentation, management, and outcomes of post-transplant lymphoproliferative disorder in renal and pancreas transplantation: a 22-year experience.\nAbstract: Post-transplant lymphoproliferative disorder (PTLD) is a life-threatening complication of solid organ transplantation associated with long-term immunosuppression and Epstein-Barr virus (EBV) reactivation. This study analyses the clinical presentation, diagnostic pathways, therapeutic strategies and outcomes of PTLD in renal and pancreatic transplant recipients at the Manchester Centre for Transplantation. A retrospective cohort study was carried out on a cohort of 73 patients diagnosed with PTLD between 2002 and 2025 following renal, simultaneous pancreas-kidney (SPK) or pancreas-only transplantation. Data were collected from electronic medical records and analysed descriptively. Clinical presentations were categorised into organ system involvement. Time from presentation to diagnosis and survival outcomes were assessed. The median time from transplant to PTLD diagnosis was 132 months, with 56% of cases diagnosed more than 10 years post-transplant. Monomorphic PTLD, in particular diffuse large B-cell lymphoma (DLBCL), was the most common subtype. EBV-positivity was seen in all early cases and in 57% overall. Abdominal and B symptoms were the most frequent presentations. Bleeding and/or anaemia were significantly associated with diagnostic delay (p\u2009=\u20090.045), and delays over one month were associated with reduced survival (p\u2009=\u20090.061). Complete or partial remission was achieved in 75% of patients. The 5-year overall survival rate was 68% while 1-year survival was 83% and death-censored graft survival was 82%. In our cohort, PTLD in transplant recipients presents with diverse symptoms and can occur several years post-transplant highlighting the need for long-term vigilance. Streamlined referral pathways and increased awareness could reduce diagnostic delays. Establishing a national PTLD registry would benefit future research.\n\nID: 42387393\nTitle: Prevalence and kinetics of viral infections during the first 100\u2009days after pediatric hematopoietic stem cell transplantation at the Children's Hospital in Rabat.\nAbstract: Viral infections are a major cause of morbidity and mortality in pediatric patients undergoing hematopoietic stem cell transplantation (HSCT), particularly during the first 100\u2009days post-transplant, a period of profound immunosuppression. Data on their prevalence and kinetics in low- and middle-income countries, including Morocco, remain limited. This study aimed to evaluate these infections at the Children's Hospital in Rabat. We conducted a retrospective descriptive study of pediatric patients who underwent HSCT at the Children's Hospital in Rabat from January 2018 to June 2025. Post-transplant viral monitoring included weekly quantitative PCR for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) until day 100. Targeted PCR for adenovirus, BK virus, HHV-6, and respiratory viruses was performed in symptomatic patients. Out of 33 patients, CMV was the most frequently detected agent, with an incidence of 51,5% (n\u2009=\u200917), of which 30.3% had a viral load\u2009>\u20092.5 log\u2081\u2080 IU/ml. The median time to first reactivation was 3\u2009weeks (IQR: 2-6). The vast majority of episodes occurred in seropositive (R+) recipients, mainly D+/R+. The highest viral loads were observed in patients with CMV viremia temporally associated with pulmonary involvement (2.62 log\u2081\u2080 IU/ml [IQR: 0.00-3.42]) compared to those without pulmonary involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04]; p\u2009=\u20090.007), despite the absence of virological confirmation of CMV-related pulmonary disease. Similarly, patients with gastrointestinal (GI) complications had higher viral loads (3.13 log\u2081\u2080 IU/ml [IQR: 2.23-3.89]) compared with those without GI involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04], p\u2009=\u20090.002). Concerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant. Infections were more frequent in recipients who were initially seronegative (D+/R-) included 8 of 13 patients (61.5%), No cases of post-transplant lymphoproliferative disease were reported. BK virus showed an early peak of infection between the 1st and 4th week, strongly associated with the occurrence of hemorrhagic cystitis, highlighting its significant clinical impact during this period. This study highlights the particularly early kinetics of CMV, BK virus, and EBV in our pediatric patients after HSCT, with CMV appearing around week 3, transient EBV reactivations in initially seronegative patients, and an early BK virus peak linked to hemorrhagic cystitis.\n\nID: 42384871\nTitle: Advances in Multiple Sclerosis.\nAbstract: Multiple sclerosis is a chronic autoimmune disorder that affects the central nervous system, causing episodes of neurologic dysfunction and often gradual disease progression. The immune system primarily targets myelin, the protective covering of nerve fibers, leading to inflammation and damage, and secondary neurodegeneration is a major cause of long-term disability. Common symptoms include vision problems, sensory disturbances, muscle weakness, balance difficulties, and bladder dysfunction. Important advances in treatment have improved outcomes in patients with relapsing forms of multiple sclerosis, particularly through highly effective immune-modifying therapies such as CD20-targeting monoclonal antibodies. However, treatment options for progressive forms remain limited, which highlights the need for therapies that can prevent progression and promote myelin repair. Comprehensive symptom management and lifestyle support are also essential to maintaining quality of life and reducing disability.\n\nID: 42384430\nTitle: Viruses, Periodontitis, and Systemic Diseases.\nAbstract: Viruses are increasingly recognized as potential modulators of oral biofilm ecology and periodontal inflammation, expanding the traditional bacterial paradigm of periodontitis. Members of the Herpesviridae family, including Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus (HSV), are frequently detected in periodontal tissues and may influence disease activity through latency, reactivation, immune modulation, epithelial barrier disruption, and interactions with bacteria. These processes may contribute to local dysbiosis and sustained periodontal inflammation. The potential systemic relevance of oral viruses is biologically plausible but remains incompletely established. Viral persistence or reactivation in oral niches may contribute to systemic immune activation through hematogenous spread, saliva-mediated dissemination, aspiration, or amplification of inflammatory mediators as IL-1\u03b2, IL-6, and TNF-\u03b1. Accordingly, viruses may act as disease modifiers within the broader relationship between periodontitis and systemic conditions including cardiovascular, metabolic, respiratory, neurogenerative, pregnancy-related, and cancer-associated outcomes. However, the strength of evidence differs across these conditions. Current data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden. Nevertheless, most available evidence is observational, associative, or derived from mechanistic experimental models, and definitive proof that viruses are independent etiopathogenic drivers of periodontitis is lacking. Future longitudinal and interventional studies are needed to determine whether viral detection reflects bystander association, disease amplification, or a true pathogenic role, and whether antiviral or phage-based strategies offer clinical benefit beyond established periodontal therapy.\n\nID: 42382261\nTitle: Cryptococcus gattii meningitis with a pulmonary cryptococcoma and cerebrospinal fluid epstein-barr virus reactivation: A diagnostic challenge.\nAbstract: This report describes a case of Cryptococcus gattii meningitis in an immunocompetent man that was initially misdiagnosed as Epstein-Barr virus meningitis and treated with steroids.

Vaccine efficacy and safety need many field years of study; time constraints due to the pandemic limited the same. A hospital-based study was done in South India among patients who presented with immune-mediated disorders in temporal correlation with COVID-19 vaccination. The study period was 20 months, from March 2020 to November 2021. There were a total of 3,235 patients with neurological issues seen in two tertiary institutions, catering predominantly to patients from lower socio-economic strata in South India. A total of 1,007 (31.12%) patients had\u00a0received COVID-19 vaccination (single dose in 511 [50.7%] and both doses in 496 [49.3%]). The general prevalence of primary demyelinating disease was compared with the background of vaccine-induced demyelination. Chi-square test was utilised for determining the association between neurological sequelae and the type of vaccine administered. Eighteen patients had neurological sequelae, and 16 had a monophasic pattern. Recurrent autoimmunity was seen in two patients who took the Sputnik vaccine. Comparing the prevalence of primary multiple sclerosis (MS) versus vaccine-induced demyelination, there was a statistically significant difference (\u03c7 2 = 572.38; p < .001), which indicates a definite role of vaccination in these patients. The association between neurological manifestations of Covishield and Covaxin showed no statistically significant difference in neurological sequelae (\u03c7 2 = 0.0466; p = .8). The Sputnik vaccine was not considered, as the number was less than five. Anti-myelin oligodendrocyte glycoprotein-associated recurrent optic neuritis was seen in one patient, and tongue atrophy, pyramidal signs, ulcerative colitis and arthritis after 3 months, and C-ANCA positivity were seen following the Sputnik vaccine in one patient. Vaccination is an effective public health intervention. However, in susceptible individuals, it can probably trigger a recurrent and multisystem event by immune dysregulation. The association is an observation-based postulate that needs a longer, larger follow-up. As per this study, it is non-fatal and remits permanently.\n\nID: 42381886\nTitle: Unlocking the healing power of Berberine: A promising aid for multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a debilitating autoimmune disorder characterized by inflammatory demyelination and progressive neurodegeneration within the central nervous system (CNS). Despite advances in disease-modifying therapies (DMTs), current treatments primarily mitigate relapses and slow disease progression but fall short in comprehensively addressing cumulative disability or neurodegeneration. Berberine (BBR), a naturally occurring isoquinoline alkaloid, has emerged as a promising therapeutic candidate due to its potent immunomodulatory, anti-inflammatory, and neuroprotective properties. In this narrative review, we synthesize the molecular mechanisms underpinning BBR's effects on MS pathology and evaluate preclinical evidence from MS-relevant animal models. Studies in experimental autoimmune encephalomyelitis (EAE) -the primary MS model-and the cuprizone (CPZ) -induced demyelination model demonstrate that BBR (typically 5-300\u202fmg/kg in preclinical protocols) reduces pro-inflammatory cytokines, modulates immune responses, and promotes remyelination-processes critical for counteracting MS-associated neurodegeneration. BBR modulates key signaling pathways, including JAK/STAT and SPHK1/S1P, which are pivotal in attenuating immune-mediated damage and preserving blood-brain barrier (BBB) integrity. Despite its therapeutic potential, challenges such as poor bioavailability and suboptimal pharmacokinetics have spurred investigations into advanced delivery systems. Nanoformulations, particularly BBR-loaded iron oxide nanoparticles (BBR-IONP), have shown superior efficacy in preclinical models by enhancing CNS delivery and improving remyelination outcomes. By highlighting BBR's multifaceted bioactivities, this review underscores its promise as a complementary or alternative approach to address unmet needs in MS management, while acknowledging the critical need for clinical trials to validate these preclinical findings.\n\nID: 42407186\nTitle: Inhibition of toll-like receptor 4 by allicin suppresses mitochondrial DNA-mediated inflammation and pyroptosis to alleviate myocardial ischemia-reperfusion injury.\nAbstract: Mitochondrial DNA (mtDNA) leakage after myocardial ischemia/reperfusion (MI/R) injury activates inflammation and pyroptosis. Although toll-like receptor 4 (TLR4) is a known mediator of MI/R injury, its interplay with mtDNA remains unclear. This study investigates the cardioprotective mechanism of allicin, focusing on its disruption of the TLR4-mtDNA axis. This study aimed to clarify the mechanisms of inflammatory response and pyroptosis in MI/R injury and the therapeutic targets of allicin. The cardioprotective mechanism of allicin was investigated in both in vivo and in vitro MI/R models. In Sprague-Dawley rats, different concentrations of allicin were administered pre-reperfusion. Myocardial injury, cytosolic mtDNA leakage, and activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) and nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing 3 (NLRP3)-gasdermin D (GSDMD) pathways were assessed. Network pharmacology combined with molecular dynamics simulation identified TLR4 as a candidate signaling pathway for validation. In H9C2 cells subjected to OGD/R, the role of TLR4 in mtDNA-induced inflammatory response and pyroptosis, and the therapeutic mechanism of allicin, were studied using TLR4 agonist RS09 and inhibitor resatorvid. Myocardial injury markers, cytosolic mtDNA leakage, cGAS-STING and NLRP3-GSDMD pathway activity, and TLR4 expression were measured. In vivo experiments demonstrated that allicin alleviated MI/R injury, suppressed cytosolic mtDNA leakage, and inhibited the cGAS-STING-mediated inflammatory response and the NLRP3-mediated pyroptosis pathways. Subsequent network pharmacology and molecular dynamics simulation identified TLR4 as a potential mediator of these effects. In vitro studies revealed that TLR4 activation promotes mtDNA-dependent inflammation and pyroptosis, which were effectively suppressed by allicin or TLR4 inhibition. TLR4 activation aggravates MI/R injury by promoting mitochondrial damage and cytosolic mtDNA leakage, which activates the pro-inflammatory (cGAS-STING) and pro-pyroptotic (NLRP3-GSDMD) pathways. Allicin protects against MI/R injury by inhibiting TLR4 activation and the subsequent mtDNA-induced pathways, thereby reducing inflammation and pyroptosis.\n\nID: 42406535\nTitle: Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway.\nAbstract: Pyroptosis is an inflammatory type of programmed cell death that may contribute to epilepsy initiation and progression through neuroinflammation. Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n\nID: 42404625\nTitle: Engineering manganese-based immune amplifier for chemoimmunotherapy of peritoneal metastatic colorectal cancer.\nAbstract: Current immunotherapies exhibit limited clinical efficacy in patients with colorectal cancer (CRC). While manganese ions (Mn) can activate the cGAS-STING pathway to potentiate innate immunity, their clinical application is limited by poor tumor accumulation and potential systemic toxicity. Alendronate (ALN), an FDA-approved agent, exerts T cell immunomodulatory activity but is hampered by low bioavailability and undesired bone targeting. To effectively potentiate antitumor immunity against CRC, we developed a manganese-alendronate (MnALN) nanomedicine via infinite coordination, leveraging Mn and ALN to synergistically eliminate tumor cells. In addition, Mn triggers reactive oxygen species (ROS)-mediated endoplasmic reticulum (ER) stress and subsequent immunogenic cell death (ICD) in tumor cells, while its combination with ALN further enhances T cell immune responses, ultimately achieving efficient tumor growth inhibition and intense anti-tumor immune response. This study presented a dual-functional MnALN nanomedicine synthesized from clinically available Mn and ALN, simultaneously activating apoptosis and inflammation-related pathways in CRC cells, which provides an effective strategy for immune tolerance CRC therapy.\n\nID: 42399115\nTitle: Corrigendum to \"Bone marrow mesenchymal stem cells senescence induced by LCCP through activation of cGAS-STING-mediated inflammation\" [Ecotoxicol.

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration.\n\nID: 42393712\nTitle: The mitochondrial protease, LonP1, is a potential cardioprotective target for attenuating doxorubicin-induced cardiomyocyte death.\nAbstract: Doxorubicin (DOX), a first-line chemotherapeutic agent, has been linked to severe off-target cardiotoxicity in the clinic. Previous works suggest that mitochondria are key mediators of this cardiotoxicity. Leakage of mitochondrial contents after DOX treatment, including mitochondrial DNA (mtDNA), is thought to activate apoptotic and inflammatory signaling pathways implicated in cardiomyocyte cell death. Whether the master mitochondrial protease, LonP1, can dampen these pathways and improve cardiomyocyte viability following DOX treatment remains unknown. Human cardiac cells (AC-16) and primary (1\u00b0) human cardiomyocytes were subjected to DOX treatment, followed by bulk RNA-Seq, RT-qPCR, qPCR, and immunoblotting to assess apoptotic signaling, inflammatory signaling, mtDNA release, and LonP1 expression, respectively. Lentivirus transduction of AC-16 cells was used to generate both knockdown (KD) and overexpression (OE) LonP1 cell lines to determine the effects of altered LonP1 levels on DOX-induced apoptosis and mtDNA release. Further, levels of mitochondrial DNA (mtDNA) were measured using qPCR from serum samples obtained from patients undergoing DOX treatment to assess the clinical relevance of released mtDNA as a potential biomarker for the development of DOX cardiotoxicity. DOX treatment of AC-16 cells, as well as 1\u00b0 human cardiomyocytes, upregulated both apoptotic and inflammatory signaling in both cell models. Increased LonP1 levels were also observed under DOX treatment in AC-16 cells and 1\u00b0 human cardiomyocytes. Likewise, DOX increased mtDNA release from both cell lines, both prior to, and as a sequel to cell death. Decreasing LonP1 levels exacerbated DOX-mediated apoptotic signaling and mtDNA release, whereas overexpression of LonP1 attenuated these effects. Furthermore, DOX treatment in cancer patients increases plasma mtDNA levels. These findings suggest LonP1 plays a protective role in the heart following DOX treatment, supporting LonP1 as a potential novel therapeutic target for prevention of DOX cardiotoxicity. Patterns of mtDNA release within patients undergoing DOX treatment also highlight the potential of mtDNA as a potential biomarker and target for prevention of DOX cardiotoxicity, justifying the need for more extensive, prospectively monitored cohort studies to expand upon these findings and statistically model mtDNA release patterns.\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.

These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. \n\nPathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway. However, the exact timing and necessity of these pathways in the specific context of EBV-triggered microglial activation demand more rigorous scrutiny, as individual research components link viral persistence to primed microglial phenotypes marked by elevated MHC-II expression and heightened immune reactivity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* EBV persistence is observed in the CNS of MS patients, but not in neurologically healthy individuals, suggesting a unique pathogenic niche.\n* Prior infection with a gammaherpesvirus sensitizes the host to a second, unrelated inflammatory stimulus, accelerating CNS demyelination.\n* The cGAS-STING pathway is both a pro-inflammatory driver in disease and a potentially protective node depending on its activation state, with down-regulation observed in some RRMS patients.\n* Neurons themselves can induce STING in response to inflammatory stress triggered by glutamate excitotoxicity, independent of microglial signaling.\n* Microglial activation in the spinal cord is often dysfunctional, characterized by ameboid morphology and delayed phagocytosis compared to the brain.\n* Ataxin-1, a gene linked to MS risk via genome-wide association studies, modulates B-cell biology and is enriched in memory and precursor B-cell subsets.\n* Viral reactivations post-transplant follow early kinetics, with BK virus associated with hemorrhagic cystitis and EBV showing transient fluctuations.\n* Berberine and similar alkaloids offer neuroprotective effects, potentially by modulating the JAK/STAT signaling pathway to reduce inflammatory demyelination.\n* Mitochondrial DNA leakage serves as an inflammatory trigger, activating cGAS-STING-mediated pyroptosis in astrocytes in epilepsy models.\n* Clinical disability progression in MS may occur independently of acute inflammatory attacks, pointing toward smouldering inflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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."

The Global Burden of Disease Study estimated that more than 10 million individuals were affected in 2020, a figure projected to double by 2040. Pathologically, PD is characterised by the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). Although early mechanistic work centred on gross anatomical changes and neuronal injury, converging evidence now positions neuroinflammation as an early and causal driver of DA neurodegeneration across the entire PD continuum. While cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING)-dependent innate immune signaling has been implicated in several neurodegenerative disorders, its contribution to PD has remained undefined. Here, using complementary in vitro and in vivo PD models, we demonstrate that mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction. Genetic knockdown of STING markedly attenuated DA neuronal demise and preserved motor performance, identifying STING-mediated neuroinflammation as a critical mediator of DAergic neurodegeneration in MPTP-induced motor deficits. Collectively, our data indicate that selective inhibition of the cGAS-STING inflammatory cascade robustly mitigates MPTP-induced nigrostriatal DA neurodegeneration and motor deficits in mice, and nominate this pathway as a tractable therapeutic target for disease-modifying intervention in PD."

We performed an integrated multiomic characterization of small extracellular vesicles (sEVs) released from spontaneous lymphoblastoid cell lines (SLCLs) derived from healthy donors and patients with MS, transformed ex vivo by endogenous wild-type EBV. Proteomics identified over 6,000 shared proteins enriched in nucleic acid-binding and chromatin-associated factors. EV-associated DNA resolved into two structurally distinct compartments: DNase-sensitive, high-molecular weight DNA associated with the vesicle corona and DNase-resistant, nucleosome-sized (\u223c130-150 bp) DNA. Both compartments were overwhelmingly host-derived and broadly genomically distributed, whereas EBV DNA was minimal. In contrast, viral RNA cargo was dominated by the EBV noncoding RNA EBER1, which was strikingly enriched across all lines and confirmed within individual vesicles by ddPCR and super-resolution microscopy. EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency, pointing to EV-mediated export of EBER1 as a candidate mechanism linking peripheral EBV infection to distal tissue signaling in MS and beyond."

The cGAS-STING pathway, a central cytosolic DNA-sensing mechanism essential for antiviral defense, antitumor immunity, and inflammatory regulation, is profoundly influenced by the metabolic milieu. However, the precise role of lactylation in modulating this pathway remains to be systematically synthesized. This review aims to comprehensively analyze the molecular mechanisms by which lysine lactylation regulates the cGAS-STING signaling axis, and to discuss the pathophysiological implications and therapeutic potential of targeting this modification in diseases ranging from autoimmunity and neuroinflammation to cancer. A comprehensive review of the relevant literature was conducted to summarize the biochemical basis of lactylation (including writers, erasers, and readers) and to systematically examine emerging evidence demonstrating direct and indirect regulation of cGAS-STING components by lactylation. Studies involving site-specific modifications, disease models, and therapeutic interventions were collated and analyzed. Lactylation directly targets core pathway components-cGAS at residues such as K21, K131, K156, K162, K275, and K409, and STING-altering their stability, enzymatic activity, DNA-binding capacity, phase separation, and downstream signaling outputs. Depending on context, lactylation exerts dual effects: it stabilizes cGAS and amplifies type I interferon responses in autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis) and hypoxic-ischemic encephalopathy, but promotes cGAS degradation or suppresses STING activity in cancer (lung adenocarcinoma, glioblastoma) and neuropathic pain, thereby facilitating immune evasion or pain sensitization. Indirectly, lactylation modulates cytosolic DNA ligand availability by influencing mitochondrial DNA release (via HMGB1, VDAC1, Arg1, DRP1) or DNA repair (via KU70). The discovery of specific lactyltransferases (AARS1/2, p300) and delactylases (SIRT1-3, HDAC1-3) establishes lactylation as a dynamic, enzymatically controlled process. Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner. Targeting the lactylation regulatory axis-by inhibiting pathogenic lactylation to restore anti-tumor immunity or enhancing it to dampen deleterious inflammation-offers a novel immunometabolic therapeutic strategy for autoimmune disorders, chronic infections, neurodegeneration, and cancer."

While essential for host defense and immune surveillance, inappropriate or sustained activation of this pathway can drive chronic inflammation, autoimmunity, and disease-associated immune dysfunction, which can promote cancer growth. Effective immunity therefore depends on precise regulatory control that restrains cGAS/STING activity under homeostatic conditions while preserving the capacity for swift and robust responses to diverse danger signals. In this Review, we synthesize emerging principles that regulate cGAS/STING signaling across cellular contexts to control signal initiation, amplification, and termination. We discuss how disruption, persistence, or pathological rewiring of these regulatory processes contributes to immune imbalance across health and disease, promoting chronic inflammation, immunosuppression, and tissue pathology, with particular relevance to tumor progression and therapeutic resistance. Finally, we consider how restoring appropriate cGAS/STING regulation, rather than simply enhancing or inhibiting pathway activity, may reestablish immune homeostasis and improve therapeutic outcomes in cancer and other inflammatory diseases, framing the pathway as a dynamic regulatory circuit rather than a simple linear signaling cascade."

Here, we identify the histone acetyltransferase KAT7 (HBO1) as a central epigenetic regulator that links chromatin remodeling to mitochondrial immune activation. KAT7 and its histone mark H3K14ac are elevated in microglia from 5\u00d7FAD mice and human AD brains. Integrative transcriptomic and epigenomic analyses reveal that KAT7 activates transcription of cytidine/uridine monophosphate kinase 2 (Cmpk2), a mitochondrial kinase essential for mtDNA synthesis. Loss of KAT7 reduces Cmpk2 expression, impairs mtDNA replication and release, and consequently suppresses cyclic guanosine monophosphate-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NLRP3 signaling. Importantly, both microglia-specific deletion and pharmacological inhibition of KAT7 mitigate cytosolic mtDNA-induced neuroinflammation, decrease \u03b2-amyloid burden, restore synaptic plasticity, and improve cognitive function in 5\u00d7FAD mice.

However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration."

This study sought to determine whether cGAS-STING-mediated microglial activation and aberrant synaptic pruning underlie sevoflurane-induced cognitive deficits and to assess how environmental conditions modulate these processes. Neonatal mice underwent sevoflurane exposure followed by rearing in enriched (EE) or impoverished (IE) environments. Cognitive function, synaptic structure, microglial activity, mitochondrial status, and cGAS-STING signaling were evaluated using behavioral tests, immunostaining, biochemical assays, and pharmacological inhibition. Sevoflurane exposure induced cognitive impairment, microglial overactivation, mitochondrial dysfunction, and excessive synaptic pruning resulting from microglial overactivation. EE mitigated these abnormalities by preserving mitochondrial integrity and reducing mtDNA-driven cGAS-STING activation, thereby preventing the microglia-mediated imbalance in synaptic pruning and improving cognitive outcomes. In contrast, IE exacerbated mitochondrial injury, aggravated synaptic loss, and further worsened cognitive impairment. Sevoflurane disrupts neurodevelopment through a mitochondria-cGAS-microglia-synapse pathway. Environmental enrichment offers significant neuroprotection, highlighting both cGAS-STING signaling and early-life environmental modulation as promising targets for preventing anesthesia-related neurodevelopmental injury."

The hallmarks of the disease are amyloid plaque accumulation, microglia and astrocyte activation, and loss of presynaptic structure leading to cognitive decline. Recently, oligodendrocyte (OL) and myelin abnormalities have emerged as important contributors to the pathogenesis of AD. In normal brain homeostatic conditions, OL maintain neuronal health through myelin axon interactions and by supplying neurotrophic and metabolic support. How strengthening OL function may support neuronal health in AD neurodegeneration remains to be fully characterized and represents a gap in knowledge and a missed therapeutic opportunity. This study sought to examine how myelin and OL may improve neuronal deficits associated with AD. We have generated a novel mouse model (AD/cKO) by crossing the AppNL-G-F mouse, an established AD model, which carries three human AD mutations in the mouse App gene, with the FusOLcKO whose OL depleted of Fus (Fused in Sarcoma) produce thicker myelin associated with greater cholesterol biosynthesis. We evaluated spatial memory function with standardized cognitive testing. We evaluated microglia density and state, astrocytic activation and toxic phenotype, myelin density, cholesterol content, amyloid plaque burden, presynaptic structures, and neuronal hypoxic and oxidative damage in the hippocampus and cortex. We characterized the transcriptome of AD/cKO hippocampal OL compared to AD by using single-cell transcriptomic studies. Spatial working memory was fully preserved in the aged AD/cKO mouse relative to the AD mouse. This outcome was associated with reduced neuronal oxidative damage, preserved presynaptic structures at the amyloid plaque niches, and a shift in microglia state at the niches in both hippocampus and cortex. In contrast, amyloid plaque burden and microglia density were decreased in the hippocampus but not in cortex, uncoupling the neuronal and microglia effects from the amyloid burden. Fus dependent myelin increase was present in both hippocampus and cortex. Single-cell transcriptomics of AD/cKO hippocampal OL revealed upregulation of energy metabolism and antioxidant genes, suggesting a role of OL enhanced energy metabolism in mediating protection of neurons and affecting microglia state in AD pathology. This work provides new insight into how oligodendrocytes may protect neurons in AD, communicate with other glial cellular players, and point to potential targets for disease intervention aimed at slowing AD progression."

In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair."

This study investigates the mechanisms underlying PDN and aims to identify potential molecular treatment targets. Male C57BL/6\u00a0J wild-type mice were employed to establish a PDN model, receiving intrathecal administration of shRNA targeting Galectin-3 (sh-Gal-3), shRNA targeting YTHDF1 (sh-YTHDF1), a YTHDF1 overexpression vector, or the m6A inhibitor 3-deazaadenosine (3-DAA), either individually or in combination. Macrophages underwent gene knockdown or overexpression and/or treatment with the glycolysis inhibitor 2-deoxy-d-glucose (2-DG) or 3-DAA. Diabetes was confirmed by monitoring blood glucose levels. Pain behavior was evaluated using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) assessments. Expression levels of Gal-3 and YTHDF1 were analyzed via Real-time PCR and Western blot, while myelin phagocytosis was evaluated through immunofluorescence and/or transmission electron microscopy. Glycolysis was assessed by measuring glucose uptake, lactate production, extracellular acidification rate (ECAR), and oxygen consumption rate (OCR). The RNA pull-down assay facilitated the detection of YTHDF1 binding to Gal-3 mRNA, and the half-life of Gal-3 mRNA was measured following transcription blockade using actinomycin D. Additionally, meRIP-qPCR assessed the m6A modification on Gal-3 mRNA. In vivo analyses revealed upregulation of Gal-3, which colocalized with IBA1. Silencing Gal-3 alleviated mechanical allodynia and diminished myelin phagocytosis. In vitro, Gal-3 silencing inhibited glycolysis, while Gal-3 overexpression enhanced myelin phagocytosis, an effect reversed by 2-DG treatment. Furthermore, high glucose stimulation elevated YTHDF1 expression, subsequently increasing Gal-3 levels; this induction was abrogated by YTHDF1 knockdown. Mechanistically, YTHDF1 enhanced Gal-3 mRNA stability through an m6A-dependent mechanism, promoting glycolysis and myelin phagocytosis. Consistently, YTHDF1 overexpression exacerbated PDN symptoms and myelin phagocytosis in vivo, which were mitigated by YTHDF1 knockdown or 3-DAA administration. YTHDF1 enhances Gal-3 mRNA stability and expression via an m6A-dependent mechanism, thereby facilitating glycolysis and myelin phagocytosis in PDN."

Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention."

Mice were subjected to 90\u2009min of ischemia followed by reperfusion, and the effects of the ferroptosis inhibitor UAMC-3203 on infarct evolution and post-stroke histological changes were examined. UAMC-3203 increased the survival of CD13-positive pericytes within infarct areas and enhanced infarct reduction in the subacute phase. In vitro, the glutathione peroxidase 4 inhibitor RAS-selective lethal 3 (RSL3) induced dose-dependent cell death in pericytes but not in endothelial cells, which was suppressed by UAMC-3203 but not by inhibitors of apoptosis or necroptosis. RSL3 induced lipid peroxidation in pericytes, as evidenced by malondialdehyde accumulation.

Tunneling nanotubes (TNTs) are dynamic F-actin-based intercellular connections which transfer mitochondria and pathogenic factors. Although TNTs have been implicated in various neuropathological conditions, their precise involvement in CM pathogenesis, particularly in relation to microglial activation, remains undefined. In this study, single-cell RNA-sequencing (scRNA-seq) revealed significant dysregulation of TNT-associated genes and actin cytoskeleton pathway remodeling in microglia of ECM model. In vitro studies demonstrated that Plasmodium-infected red blood cells (pRBCs)-stimulated primary microglia formed extensive F-actin-rich tunneling nanotubes, which mediated the bidirectional transfer for mitochondria and facilitated intercellular trafficking of lysosomal contents and malarial pigment. These TNT-mediated intercellular communication amplified microglial activation, as evidenced by: (i) lipid peroxidation, (ii) mitochondrial dysfunction, and (iii) autophagosome (LC3+) accumulation. This process further amplifies neuroinflammation through TNF\u03b1/IL-6 secretion and expansion of CD45high microglial populations. Pharmacological TNT inhibition restores microglial homeostasis in ECM model. In conclusion, TNTs mediate neuroinflammation in the ECM model by transferring mitochondria and malarial pigment between microglia. Although mitochondrial transfer may transiently support cellular homeostasis, progressive malarial pigment accumulation triggers lipid metabolism dysregulation and amplified neuroinflammation. Inhibiting TNTs formation attenuates microglial hyperactivation, highlighting targeted regulation of TNT-mediated intercellular communication as a potential therapeutic approach for CM-associated neuropathology."

To date, the precise molecular mechanisms remain incompletely understood. Herein, we showed that DON triggers neurotoxicity by reprogramming microglial glycolysis via activation of the NQO1/NF-\u03baB pathway. Raffinose (Raf), a natural trisaccharide, effectively attenuated DON-induced neuroinflammation in vivo and in vitro. Mechanistically, Raf upregulated NQO1 transcription by selectively binding to Nrf2 at Val-514 and Cys-368, thereby reinforcing the NQO1-I\u03baB\u03b1 interaction, possibly through NQO1-associated regulatory interfaces. This interaction inhibited NF-\u03baB hyperactivation, suppressed glycolysis, and restored oxidative phosphorylation, thereby attenuating DON-induced pro-inflammatory microglial activation.

This inflammatory process unfolds years before clinical symptoms, creating an opportunity for early intervention. In vivo imaging technologies that could detect and quantify microglial reactivity are therefore essential for early diagnosis, patient stratification, and evaluating emerging immunomodulatory therapies that target this fundamental driver of PD progression. Yet no standardized, sensitive, and specific technology currently achieves this goal. Molecular magnetic resonance imaging (mMRI) is uniquely suitable to address this problem because it integrates inherent high spatial resolution and soft-tissue contrast of conventional MRI with molecularly targeted contrast agents, enabling simultaneous acquisition of anatomical detail and functional/biological information at submillimeter isotropic resolution. Here we present a novel mMRI probe designed to specifically target colony stimulating factor-1 receptor, expressed primarily on microglia in the brain. In silico data show that the targeting ligand binds the extracellular Ig domain of the receptor. In vitro cell uptake studies with both murine and human microglia cell lines show that the probe binds the receptor triggering active cell uptake and in vivo MRI enabled effective separation of the A53T mouse model of Parkinson's disease from control mice using radiomics-assisted MR image analysis. Ex-vivo immunohistochemical analysis showed signal from the probe largely in the cytosolic compartment of IBA-1 reactive cells, confirming that the observed in vivo MRI signal is due primarily to retention of the agent by microglia. This novel technology has the potential to interrogate the rgional presentation of microglial activation in PD. A microglia targeted MRI probe generates disease-specific contrast after injection, clearly distinguishing A53T Parkinsonian mice from controls."

This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS."

Human umbilical cord blood mononuclear cells (hUCB-MNCs) have shown neuroprotective and immunomodulatory properties; however, their therapeutic efficacy and underlying mechanisms in VaD remain incompletely understood. In this study, we investigated the effects of hUCB-MNCs treatment in a mouse model of VaD induced by bilateral common carotid artery stenosis (BCAS). Behavioral assessments showed that hUCB-MNCs treatment improved cognitive performance, affective-like behaviors, and motor coordination in BCAS mice. Histopathological analyses demonstrated that hUCB-MNCs treatment attenuated white matter injury, preserved myelin integrity, and mitigated neuronal and synaptic damage. Integrated transcriptomic and proteomic analyses of corpus callosum (CC) tissues revealed enrichment of immune-regulatory, phagocytosis-related, and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT)-associated pathways after hUCB-MNCs treatment. In vivo and in vitro analyses further indicated that hUCB-MNCs helped preserve microglial homeostatic features and improved myelin debris-handling responses. Collectively, these findings suggest that hUCB-MNCs ameliorate VaD-associated pathology, at least in part, by modulating microglial myelin debris-handling responses and PI3K/AKT-related signaling, highlighting hUCB-MNCs as a promising cell-based therapeutic candidate for VaD."

While mitochondrial DNA leakage and cGAS-STING activation are verified drivers of neuroinflammation and white matter pathology in various neurological conditions, the evidence linking these to EBV specifically is limited to the potential role of extracellular vesicles (sEVs) in disseminating viral components such as EBER1.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenesis of Multiple Sclerosis is increasingly recognized as a multi-axial process involving both peripheral immune triggers and chronic, compartmentalized neuroinflammation. Epigenetic and metabolic studies indicate that \"Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression.\" Specifically, the cGAS-STING axis has emerged as a major mediator of such progression, as \"mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction.\" \n\nWhile EBV is a strong candidate as an MS trigger, its precise mechanism of CNS influence remains under scrutiny. Current literature identifies sEVs as a vector for viral components, noting that \"EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency\". However, the direct, causal coupling of EBV-encoded products to cGAS-STING activation in microglia, and the subsequent extent of myelin loss, requires further investigation. We observe that \"Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner,\" suggesting that viral-induced metabolic reprogramming could potentially act as a trigger.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **sEV-Mediated Viral Dissemination:** Small extracellular vesicles act as carriers for immunostimulatory EBV non-coding RNAs (EBER1) to distal tissues.\n* **cGAS-STING Rheostat:** The cGAS-STING pathway functions as a tunable control node, not merely a binary switch, making it highly sensitive to metabolic shifts.\n* **Mitochondrial DNA (mtDNA) Leakage:** Cytosolic leakage of mtDNA is a conserved activator of STING-mediated neuroinflammation across AD, PD, and ischemia models.\n* **Metabolic Checkpoints:** Lactylation of core pathway components serves as a metabolic-immune bridge regulating STING stability and activity.\n* **Regional Glial Heterogeneity:** Spinal cord and brain microglia exhibit distinct activation profiles during demyelination, complicating global neuroinflammatory models.\n* **T-Cell-Microglia Crosstalk:** Cytotoxic NK-like CD8+ T cells spatially associate with microglia in MS lesions, linking peripheral immune states to local tissue destruction.\n* **Mitochondrial Protection:** Preserving mitochondrial integrity effectively suppresses mtDNA-driven innate immune activation, as demonstrated by the efficacy of EE and other interventions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n\nID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\n\nID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.\n\nID: 42383352\nTitle: Therapeutic targeting of the cGAS-STING pathway in human disease.\nAbstract: The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is a central regulator of innate immunity that links cytosolic DNA sensing to type I IFN and inflammatory responses. While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch.\n\nID: 42372812\nTitle: Qufeng xuanbi formula attenuates HDM-induced allergic asthma by targeting the STING/HIF-1\u03b1/glycolysis axis.\nAbstract: Qufeng Xuanbi Formula (QFXBF), a traditional Chinese medicine prescription used for asthma-like respiratory disorders, has shown anti-asthmatic activity. However, whether it attenuates allergic airway remodeling through innate immune-metabolic regulation remains unknown. This study aimed to determine whether QFXBF alleviates house dust mite (HDM)-induced allergic airway inflammation and remodeling through targeting the STING/HIF-1\u03b1/glycolysis axis, and to evaluate the specific inhibitory potential of its constituent tectorigenin on STING-mediated immunometabolic signaling. An HDM-induced allergic asthma model was established in male C57BL/6 mice by intranasal sensitization and challenge, followed by oral administration of QFXBF at 12.5, 25, and 50\u202fg/kg/day or dexamethasone at 2\u202fmg/kg/day. Airway hyperresponsiveness, lung histopathology, mucus secretion, collagen deposition, \u03b1-SMA expression, inflammatory mediators in BALF and serum, and glycolytic metabolic indices were evaluated. BSMCs were stimulated with IL-4 and LPS, both at 5\u202fng/mL, and treated with QFXBF at 2, 4, and 8\u202fmg/mL. Cell proliferation, migration, glucose consumption, lactate production, RT-qPCR, Western blotting, and immunofluorescence were performed to assess airway smooth muscle activation and metabolic reprogramming. Transcriptomic analysis of lung tissue, STING overexpression, HIF-1\u03b1 pharmacological inhibition, LC-MS/MS-based identification of tectorigenin, molecular docking, and molecular dynamics simulations were further used to investigate the STING/HIF-1\u03b1/glycolysis axis and the potential STING-targeting activity of tectorigenin. QFXBF markedly reduced airway hyperresponsiveness, inflammatory infiltration, and collagen deposition in HDM-challenged mice, accompanied by decreased asthma-related markers in bronchoalveolar lavage fluid and serum. QFXBF also downregulated STING, HIF-1\u03b1, and key glycolytic enzymes at both mRNA and protein levels in lung tissue. In IL-4+LPS-stimulated BSMCs, QFXBF dose-dependently suppressed proliferation and migration, reduced glucose utilization and lactate accumulation, and concurrently inhibited STING/HIF-1\u03b1 and glycolysis-associated factors. Mechanistically, QFXBF attenuated HIF-1\u03b1 activity and glycolytic flux through suppression of STING. Liquid chromatography-based analysis identified tectorigenin as a bioavailable constituent of QFXBF. In STING-overexpressing BSMCs, tectorigenin significantly reduced STING expression, proliferative activity, and lactate metabolism, supporting STING inhibition as a key pharmacological basis of QFXBF. QFXBF can alleviate allergic remodeling by suppressing the STING/HIF-1\u03b1-mediated glycolytic program. Tectorigenin may act as a potential STING inhibitor that disrupts innate immune-metabolic signaling, providing mechanistic support for QFXBF-derived therapeutic strategies in asthma.\n\nID: 42370935\nTitle: Chronic hyperinsulinemia accelerates adipose senescence via mitochondrial dysfunction and cGAS-STING signalling.\nAbstract: Prediabetes and Type 2 Diabetes represent major global health challenges and have escalated to pandemic levels. Adipose tissue functions as a critical endocrine organ, playing a central role in maintaining glucose homeostasis during fasting, feeding, and stress responses. In this study, we demonstrated that prolonged chronic hyperinsulinemic stress increases the burden of senescent adipocytes, accompanied by activation of the cGAS-STING signalling pathway. Chronic hyperinsulinemia-induced insulin-resistant 3T3-L1 and human mesenchymal stem cell-derived adipocytes exhibited elevated senescence-associated phenotypes, mitochondrial dysfunction and impaired cellular energetics. Notably, we found that mitochondrial DNA leakage triggered the cGAS-STING pathway in insulin-resistant adipocytes and mouse models. Temporal analysis revealed that mitochondrial dysfunction was detectable at earlier stages of chronic insulin exposure, preceding activation of the cGAS-STING pathway and senescence-associated markers, supporting a progressive model of cellular dysfunction. This phenomenon was also observed in adipose depots of individuals with Type 2 diabetes, underscoring the translational relevance of our findings. Targeting cGAS or STING, either pharmacologically or through genetic silencing, significantly reduced inflammatory and senescence-related features in hyperinsulinemia-induced insulin-resistant 3T3-L1 adipocytes. Furthermore, attenuation of senescence treatment with the combination of Dasatinib and Quercetin alleviated mitochondrial stress and associated adipose dysfunction. Collectively, our findings support a model in which prolonged hyperinsulinemic stress induces early mitochondrial dysfunction, followed by activation of cGAS-STING signalling and the subsequent emergence of adipocyte senescence-associated phenotypes, contributing to adipose tissue dysfunction in insulin resistance and Type 2 Diabetes.\n\nID: 42365956\nTitle: Dive Injury and Jellyfish Sting Case Study.\nAbstract: Wildlife exposure is a risk that trained divers are fully aware of. Examples of hazardous wildlife that divers may encounter include, but are not limited to, sharks, coral, sponges, eels, and jellyfish. Encountering wildlife can lead to a diver panicking or being forced to surface rapidly or in an uncontrolled manner due to panic or avoidance of the hazard. This may increase the risk of decompression illness (DCI), mainly pulmonary overinflation syndrome (POIS). Injuries caused by hazardous aquatic wildlife can also be distracting, leading dive supervisors and/or medical personnel to overlook unrelated injuries, such as DCI. If this occurs, the affected diver may suffer a grave outcome that could otherwise have been prevented. A 23-year-old Army Engineer diver developed sharp chest pain shortly after a 70-foot SCUBA dive complicated by suspected Portuguese man-of-war envenomation. He had painful tentacle contact on both hands/arms and neck, treated immediately with oxygen, vinegar, and seawater irrigation. In the ED, he was stable with normal oxygenation, ECG, labs, venous blood gas, and troponin. His chest pain resolved within 90 minutes, and skin findings improved with topical steroids and antihistamine therapy. He was diagnosed with jellyfish envenomation and atypical chest pain rather than a diving-related injury. At one-month follow-up, he was asymptomatic with normal chest radiographs and was cleared to return to diving. It is of the utmost importance to be aware of all possible injuries or maladies that could have occurred to a diver, and for medical personnel to avoid becoming hyper-focused on a single injury, such as wildlife exposure or trauma.\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: 42352365\nTitle: Infectious Agents in Multiple Sclerosis: Viral Triggers, Antibody-Mediated Autoimmunity, and Parasitic Immunomodulation.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system characterized by demyelination, neuroinflammation, and progressive neurodegeneration. While there is a small component of genetic susceptibility to MS risk, environmental factors, including infectious exposures, are gaining increased recognition as playing a critical role in MS initiation and progression. Viral infections, especially by Epstein-Barr virus (EBV), have emerged as strong candidates and triggers of MS symptoms, through antibody-mediated molecular mimicry and B-cell dysregulation. In contrast, parasitic infections, including helminths and select protozoa, appear to exert neuroprotective effects by skewing immune responses toward regulation and tolerance. In this review, we examine antibody-driven mechanisms by which viral pathogens promote autoimmunity in MS and contrast these with parasite-induced immunoregulatory pathways that suppress pathogenic inflammation. We further discuss diagnostic and therapeutic implications, highlighting how insights from infectious immunology may inform novel strategies for MS treatment.\n\nID: 42352288\nTitle: Unmasking Indolent Systemic Mastocytosis in Patients with Unexplained or Treatment-Refractory Osteoporosis: A Case Series with Diagnostic and Therapeutic Implications.\nAbstract: Indolent systemic mastocytosis (ISM) is an under-recognised cause of secondary osteoporosis, and skeletal fragility may be the only presenting feature, delaying diagnosis. We describe four adults referred to a tertiary endocrinology service for unexplained osteoporosis or low-trauma fractures, in whom systemic mastocytosis (SM) was identified during work-up. All had elevated basal serum tryptase (41.4-87.0 \u00b5g/L), bone-marrow biopsy showing atypical mast cells and the KIT D816V variant; cutaneous lesions were absent in every case. Three patients fulfilled WHO 2022 criteria for ISM. The fourth had coexistent JAK2 V617F-positive post-essential-thrombocythaemia myelofibrosis and was classified as SM with associated haematological neoplasm (SM-AHN); his mast cell clone (tryptase 43.7 \u00b5g/L; KIT D816V VAF 0.391%) behaved indolently and contributed clinically through osteoporosis alone, illustrating that an indolent mast cell component can be overlooked when a chronic myeloid neoplasm dominates the picture. Presentations ranged from an isolated low-energy L5 fracture in a 55-year-old man, to multiple vertebral compression fractures despite denosumab in a 71-year-old woman with primary hyperparathyroidism, to severe wasp-sting anaphylaxis in a 43-year-old man. After multidisciplinary review, all received intravenous zoledronic acid with vitamin D repletion; KIT-targeted therapy is under consideration in selected patients. Although causal inferences cannot be drawn from four retrospectively identified cases, the series illustrates how ISM may be missed in unexplained or treatment-refractory osteoporosis-particularly in younger men, those with prior severe anaphylaxis, and those fracturing on antiresorptive therapy-and supports combining basal serum tryptase with high-sensitivity peripheral-blood KIT D816V testing, in line with the WHO/ICC/AIM-ECNM 2022-2024 criteria. Prospective studies are needed.\n\nID: 42336825\nTitle: Inhibition of HSPA8 alleviates experimental autoimmune encephalomyelitis via dual modulation of NLRP3 inflammasome activation: suppressing both NF-\u03baB-mediated priming and ASC-dependent assembly.\nAbstract: The pathological processes of multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are closely associated with excessive activation of inflammasomes. HSPA8 is a constitutively expressed molecular chaperone involved in cellular signaling and immune-inflammatory regulation, but its role in EAE-associated neuroinflammation remains unclear. In this study, we found that HSPA8 was significantly upregulated in the spinal cord tissues of EAE mice and positively correlated with disease severity. Immunofluorescence co-staining showed that HSPA8 upregulation was more prominently associated with Iba1-positive microglia/macrophage-enriched regions than with GFAP- or NeuN-positive regions. Intrathecal knockdown of HSPA8 attenuated EAE progression, reduced inflammatory responses, and alleviated demyelination and axonal injury. In vitro, HSPA8 knockdown reduced NLRP3 inflammasome-mediated IL-1\u03b2/IL-18 release, caspase-1 activation, GSDMD-N formation, and pyroptosis in THP-1 cells, bone marrow-derived macrophages, and BV2 microglia, and these effects were partially restored by siRNA-resistant HSPA8 rescue. Mechanistically, HSPA8 knockdown was associated with impaired NF-\u03baB-dependent priming, as reflected by reduced p65 phosphorylation, nuclear translocation, NF-\u03baB transcriptional activity, and pro-IL-1\u03b2 expression. HSPA8 is also associated with ASC, and HSPA8 knockdown impaired NLRP3-ASC interaction, ASC oligomerization, and ASC speck formation during inflammasome assembly. These findings suggest that HSPA8 is functionally associated with NLRP3 inflammasome activation through both NF-\u03baB\u2011dependent priming and ASC\u2011associated assembly, thereby contributing to neuroinflammation in EAE. HSPA8 may represent a potential therapeutic target for MS-related and other inflammasome-driven neuroinflammatory disorders.\n\nID: 42336161\nTitle: Lamivudine ameliorates neuropathology in 5\u00d7FAD mice via coordinated inhibition of the cGAS-STING pathway with enhancement of mitophagy.\nAbstract: Alzheimer's disease is a neurodegenerative disorder for which there is currently no effective treatment available. Epidemiological and clinical evidence suggests that lamivudine, a nucleoside reverse transcriptase inhibitor, is associated with a reduced risk of Alzheimer's disease and shows potential in alleviating neuroinflammation. This study therefore aims to employ AD mouse models to further investigate the molecular mechanisms by which lamivudine ameliorates AD-related phenotypes. In this study, we showed that lamivudine administration inhibited cGAS-STING activation and attenuated mitochondrial damage in the 5\u202f\u00d7FAD mouse model, as supported by improved mitochondrial morphology and enhanced mitophagy. These changes were associated with improved spatial memory, alongside reduced neuronal apoptosis and synaptic loss. Our findings underscore the neuroprotective potential of lamivudine in AD via coordinated preservation of mitochondrial integrity and suppression of innate immune signaling, suggesting its promise for clinical translation in neurodegenerative disorders.\n\nID: 42335641\nTitle: Delphinidin targets voltage-dependent anion channel 1 to inhibit ferroptosis and protect against retinal photochemical damage.\nAbstract: The molecular basis of retinal photochemical damage remains incompletely understood, limiting the development of targeted therapeutic strategies. Delphinidin, an anthocyanidin with reported protective effects, represents a promising candidate, but its direct molecular target and mechanism of action are unclear. The molecular target of delphinidin was identified using Activity-Based Protein Profiling (ABPP), DARTS-MS, SPR, and CETSA. Its functional effects were investigated in 661 W photoreceptor cells and in a light-induced retinal damage model in Sprague-Dawley rats. Protein carbonylation was assessed via an alkynylaniline probe, and Voltage-Dependent Anion Channel 1 (VDAC1) oligomerization was examined by chemical crosslinking. Mitochondrial function, cGAS-STING pathway activation, and ferroptosis markers were evaluated to delineate the underlying mechanism. VDAC1 was identified as a direct target of delphinidin. Light exposure induced VDAC1 carbonylation and oligomerization, leading to mitochondrial dysfunction characterized by cytochrome c release and mitochondrial DNA (mtDNA) leakage into the cytosol. Cytosolic mtDNA activated cGAS-STING pathway, which in turn promoted loss of the ferroptosis suppressor GPX4 and triggered ferroptosis. Delphinidin interrupted this cascade by binding to VDAC1 and inhibiting its carbonylation and oligomerization, thus limiting mtDNA leakage, attenuating cGAS-STING activation, preserving GPX4 abundance, and inhibiting ferroptosis. In vivo, delphinidin intervention conferred significant protective effects, as evidenced by preservation of retinal histoarchitecture and reduced oxidative damage and ferroptosis, CONCLUSION: This study identifies a novel mechanistic axis in RPD linking VDAC1 dysregulation to mtDNA-driven innate immune activation and ferroptosis. It further establishes delphinidin as a direct VDAC1 targeting compound and highlights its therapeutic potential for the prevention of RPD.\n\nID: 42333565\nTitle: MYO6 Activates cGAS-STING Pathway in CD4+ T Cell to Accelerate Parkinson's Disease.\nAbstract: Immunological system dysfunction has a pivotal role in the progression of Dopamine (DA) neuronal loss in Parkinson's Disease (PD), in which CD4+ T cells are key players. The cGAS-STING pathway is involved in immune modulation. We propose to clarify the specific function of this pathway in CD4+ T cells and its potential contribution to the development of the pathogenesis of PD. We screened common differential proteins in peripheral and midbrain CD4+ T cells from PD mice by proteomic analyses and defined the common upregulated differential protein Myosin VI (MYO6) as a target protein by Protein-Protein Interaction (PPI) analysis. The expression of MYO6 and cGAS-STING pathway proteins was assayed by western blot. The validation experiment found that the upregulation of MYO6 protein expression was accompanied by the activation of the cGAS-STING pathway, including cGAS, phosphorylated- STING (p-STING)/STING, phosphorylated-TBK1 (p-TBK1)/TBK1, and phosphorylated-IRF3 (p-IRF3)/IRF3, together with increased IL-6 and iNOS expressions in peripheral and midbrain CD4+ T cells from PD mice. Strikingly, deletion of MYO6 and TBK1 in CD4+ T cells attenuated neuroinflammation and DA neuronal death. MYO6 was a novel upstream regulator of TBK1. Here, we determined that the MYO6-cGAS-STING-TBK1 cascade of signaling was involved in the progression of PD. MYO6 may be a potentially CD4+ T cell-associated target for the treatment of PD.\n\nID: 42333016\nTitle: STING Modulating ER-Phagy in the Prelimbic Cortex Neurons Contributed to Neuropathic Pain and Emotional Comorbidity.\nAbstract: Our previous data suggested that autophagy is crucial for neuropathic pain. The different cell types and varying degrees of regulation of STING may lead to a paradoxical effect on pain and emotions in the neuropathic pain model. Up to now, whether STING modulates neuropathic pain in PrL neurons via ER-phagy is still unknown. In this study, we investigated the effect of ER-phagy in the prefrontal cortex (PrL) on neuropathic pain. We administered 4-phenylbutyric acid, tunicamycin, 3-methyladenine, and rapamycin to evaluate the interaction between endoplasmic reticulum (ER) stress and autophagy in the PrL of SNL (spinal nerve ligation). We injected AAV to investigate whether ER-phagy modulated pain and emotional behaviors. We further explored whether STING and its pathway as a modulation target for ER-phagy to participate in the pain process. We injected 2'3-cGAMP and RU521 to modulate the cGAS/STING pathway in ER-phagy in SNL mice. Moreover, we modulated STING expression and regulated the levels of ER-phagy and the interaction between STING and LC3 in neurons through PrL AAV injections. The data indicated that ER-phagy alleviated the excessive ER stress induced by SNL in PrL through the cGAS/STING pathway. Regulating ER-phagy in PrL neurons through AAV tools altered pain and emotion-related behaviors. In addition, regulating STING in PrL neurons altered the comorbidity of pain and emotion. Importantly, the binding interaction between STING and LC3 in PrL neurons provides a novel target for PrL ER-phagy. Enhanced ER-phagy of PrL neurons provides analgesic, anti-anxiety, and antidepressant effects through modulating STING in SNL mice.\n\nID: 42323525\nTitle: Lactylation: a novel post-translational modification for cGAS-STING pathway.\nAbstract: Lysine lactylation (Kla) is a lactate-derived post-translational modification that has emerged as a critical metabolic-epigenetic regulator linking cellular metabolic states to innate immune signaling. The cGAS-STING pathway, a central cytosolic DNA-sensing mechanism essential for antiviral defense, antitumor immunity, and inflammatory regulation, is profoundly influenced by the metabolic milieu. However, the precise role of lactylation in modulating this pathway remains to be systematically synthesized. This review aims to comprehensively analyze the molecular mechanisms by which lysine lactylation regulates the cGAS-STING signaling axis, and to discuss the pathophysiological implications and therapeutic potential of targeting this modification in diseases ranging from autoimmunity and neuroinflammation to cancer. A comprehensive review of the relevant literature was conducted to summarize the biochemical basis of lactylation (including writers, erasers, and readers) and to systematically examine emerging evidence demonstrating direct and indirect regulation of cGAS-STING components by lactylation. Studies involving site-specific modifications, disease models, and therapeutic interventions were collated and analyzed. Lactylation directly targets core pathway components-cGAS at residues such as K21, K131, K156, K162, K275, and K409, and STING-altering their stability, enzymatic activity, DNA-binding capacity, phase separation, and downstream signaling outputs. Depending on context, lactylation exerts dual effects: it stabilizes cGAS and amplifies type I interferon responses in autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis) and hypoxic-ischemic encephalopathy, but promotes cGAS degradation or suppresses STING activity in cancer (lung adenocarcinoma, glioblastoma) and neuropathic pain, thereby facilitating immune evasion or pain sensitization. Indirectly, lactylation modulates cytosolic DNA ligand availability by influencing mitochondrial DNA release (via HMGB1, VDAC1, Arg1, DRP1) or DNA repair (via KU70). The discovery of specific lactyltransferases (AARS1/2, p300) and delactylases (SIRT1-3, HDAC1-3) establishes lactylation as a dynamic, enzymatically controlled process. Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner. Targeting the lactylation regulatory axis-by inhibiting pathogenic lactylation to restore anti-tumor immunity or enhancing it to dampen deleterious inflammation-offers a novel immunometabolic therapeutic strategy for autoimmune disorders, chronic infections, neurodegeneration, and cancer.\n\nID: 42321888\nTitle: Environmental enrichment mitigates sevoflurane-induced neurodevelopmental injury via cGAS-STING-dependent microglial modulation.\nAbstract: Neonatal exposure to sevoflurane has been implicated in long-term neurodevelopmental abnormalities, yet the underlying mechanisms remain unresolved. This study sought to determine whether cGAS-STING-mediated microglial activation and aberrant synaptic pruning underlie sevoflurane-induced cognitive deficits and to assess how environmental conditions modulate these processes. Neonatal mice underwent sevoflurane exposure followed by rearing in enriched (EE) or impoverished (IE) environments. Cognitive function, synaptic structure, microglial activity, mitochondrial status, and cGAS-STING signaling were evaluated using behavioral tests, immunostaining, biochemical assays, and pharmacological inhibition. Sevoflurane exposure induced cognitive impairment, microglial overactivation, mitochondrial dysfunction, and excessive synaptic pruning resulting from microglial overactivation. EE mitigated these abnormalities by preserving mitochondrial integrity and reducing mtDNA-driven cGAS-STING activation, thereby preventing the microglia-mediated imbalance in synaptic pruning and improving cognitive outcomes. In contrast, IE exacerbated mitochondrial injury, aggravated synaptic loss, and further worsened cognitive impairment. Sevoflurane disrupts neurodevelopment through a mitochondria-cGAS-microglia-synapse pathway. Environmental enrichment offers significant neuroprotection, highlighting both cGAS-STING signaling and early-life environmental modulation as promising targets for preventing anesthesia-related neurodevelopmental injury.\n\nID: 42321474\nTitle: TLR7 in systemic lupus erythematosus: genetics and emerging therapies.\nAbstract: Systemic lupus erythematosus (SLE) is a disease with considerable unmet treatment needs. Endosomal nucleic acid sensing by Toll-like receptor 7 (TLR7) is emerging as a key pathogenic pathway. Gain-of-function mutations in the genes encoding TLR7 and its chaperone UNC93B1 can cause monogenic childhood-onset SLE; rare variants in proteins that regulate ligand availability or downstream signalling proteins also contribute to disease. TLR7 variants can increase the affinity of this receptor for its ligands and can alter binding to endogenous antagonists. Both self RNA-protein complexes and viruses have been implicated in TLR7 activation. Key pathogenic mechanisms include breakdown in B cell tolerance and autoantibody production and type I interferon secretion. Although current therapies such as B cell-depleting chimeric antigen receptor\u00a0(CAR) T cells and anifrolumab (anti-type I interferon receptor) offer benefit, they are limited by high costs and lack of oral options. In this context, TLR7 has emerged as a promising therapeutic target. Phase II trials of an oral dual TLR7-TLR8 antagonist show durable suppression of the interferon signature in all patients, indicating that TLR7 and TLR8 drive this signature in SLE. This treatment has shown clinical benefit for SLE and cutaneous lupus erythematosus, although the primary endpoint (a dose-response effect) was only met in cutaneous lupus erythematosus. Thus, TLR7-TLR8 antagonists might reshape SLE treatment, alone or in combination with other drugs.\n\nID: 42309183\nTitle: cGAS-STING signaling pathway: a central pathological mechanism and emerging therapeutic target for postoperative cognitive dysfunction.\nAbstract: Postoperative cognitive dysfunction (POCD) is a prevalent neurological complication in older patients following surgery. However, the upstream molecular triggers of perioperative neuroinflammation, a key factor in its pathogenesis, remain insufficiently understood. This review systematically examines the emerging evidence implicating the cGAS-STING signaling pathway as a potentially central mediator in the pathological progression of POCD. Integrating recent advancements, we outline a critical pathological cascade in POCD: perioperative stressors, including anesthesia and surgical trauma, induce mitochondrial injury, resulting in the release of mitochondrial DNA (mtDNA) into the cytosol. This leaked mtDNA functions as an endogenous danger signal, activating the cGAS-STING pathway in brain microglia. Activation of this pathway drives neuroinflammation, characterized by proinflammatory (M1-like) microglial polarization, regulated cell death (e.g., pyroptosis), and a self-perpetuating cycle of mitochondrial dysfunction, ultimately leading to neuronal damage and cognitive decline. We propose the mtDNA-cGAS-STING axis as a candidate pivotal link between perioperative stress and the neuropathology of POCD, based on converging preclinical evidence. Therapeutic strategies targeting this pathway, such as cGAS-STING inhibition or the promotion of mitophagy, have shown significant neuroprotective effects in preclinical studies. These findings offer promising avenues for the prevention and treatment of POCD and highlight potential implications for perioperative neuroprotection in older adults.\n\nID: 42288132\nTitle: The leaked mitochondrial DNA activated the cGAS-STING signaling pathway and exacerbated the motor dysfunction in mice caused by MPTP.\nAbstract: Parkinson's disease (PD) is the fastest-growing neurological disorder worldwide, outpacing even the rate of population aging. The Global Burden of Disease Study estimated that more than 10 million individuals were affected in 2020, a figure projected to double by 2040. Pathologically, PD is characterised by the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). Although early mechanistic work centred on gross anatomical changes and neuronal injury, converging evidence now positions neuroinflammation as an early and causal driver of DA neurodegeneration across the entire PD continuum. While cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING)-dependent innate immune signaling has been implicated in several neurodegenerative disorders, its contribution to PD has remained undefined. Here, using complementary in vitro and in vivo PD models, we demonstrate that mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction. Genetic knockdown of STING markedly attenuated DA neuronal demise and preserved motor performance, identifying STING-mediated neuroinflammation as a critical mediator of DAergic neurodegeneration in MPTP-induced motor deficits. Collectively, our data indicate that selective inhibition of the cGAS-STING inflammatory cascade robustly mitigates MPTP-induced nigrostriatal DA neurodegeneration and motor deficits in mice, and nominate this pathway as a tractable therapeutic target for disease-modifying intervention in PD.\n\nID: 42278492\nTitle: Sex Differences in Mitochondrial Function: Endocrine Regulation, Immunometabolic Signaling, and Implications for Health and Disease.\nAbstract: Mitochondria are central regulators of cellular bioenergetics, redox balance, and signaling pathways that integrate metabolic and immune responses. Emerging evidence indicates that biological sex is an important determinant of mitochondrial function, in part through the regulatory effects of sex hormones on mitochondrial biogenesis, oxidative phosphorylation, reactive oxygen species production, and quality control mechanisms. Estrogen, testosterone, and progesterone differentially modulate mitochondrial dynamics, substrate utilization, antioxidant capacity, and immune signaling, resulting in distinct mitochondrial phenotypes that may influence disease susceptibility across the lifespan. In this review, we synthesize current knowledge on the mechanistic basis of sex differences in mitochondrial function and highlight mitochondria as key mediators linking endocrine signaling to immunometabolic regulation. We discuss how mitochondrial-derived signals, including mitochondrial reactive oxygen species, mitochondrial DNA release, and cardiolipin exposure, activate inflammatory pathways such as NF-\u03baB, cGAS-STING, and NLRP3 inflammasome signaling. These pathways may contribute to chronic inflammation, gut barrier dysfunction, and systemic metabolic disruption. We further examine the impact of major endocrine transitions, including pregnancy, the postpartum period, menopause, and androgen imbalance in conditions such as polycystic ovary syndrome, on mitochondrial function and disease risk. Particular emphasis is placed on the gastrointestinal tract as a metabolically active and mitochondria-dependent interface, where mitochondrial dysfunction may contribute to epithelial barrier disruption, microbial dysbiosis, and systemic inflammation. Finally, we discuss emerging therapeutic strategies targeting mitochondrial function, including exercise, hormone-based therapies, mitochondria-targeted antioxidants, and interventions aimed at improving mitochondrial quality control. Understanding sex-specific mitochondrial regulation may provide a framework for improved endocrine stratification, mitochondrial phenotyping, and precision medicine approaches across diverse clinical contexts.\n\nID: 42272449\nTitle: Intrinsically Mitochondria-Targeting Nanozyme via Coordination-Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia-Reperfusion Injury.\nAbstract: Mitochondrial dysfunction, culminating in oxidative stress-driven release of mitochondrial DNA (mtDNA) and subsequent inflammatory activation, constitutes a central pathogenic axis in cerebral ischemia-reperfusion injury. Disrupting this axis requires precise antioxidant delivery to neuronal mitochondria, a major therapeutic hurdle. Here, we uncover that the natural flavonoid quercetin (Quer) possesses an intrinsic ability to bind mitochondrial outer membrane proteins, revealing its unexploited potential as a natural mitochondrial-targeting ligand. Leveraging this discovery, we engineered an ultrasmall mitochondria-targeting cascade nanozyme through coordination-driven self-assembly of the natural flavonoid Quer with Fe3+. MCN currently generates Fe2+/Fe3+ dual-valence centers that confer potent, superoxide dismutase-catalase cascade catalytic enzyme activities. We further confirmed that the MCN traverse the compromised blood-brain barrier, localize within the ischemic brain, and are selectively delivered to neuronal mitochondria in a rodent stroke model. Through its cascade elimination of key ROS, MCN stabilizes mitochondrial function and prevents mtDNA leakage. By blocking the released mtDNA from activating the cGAS-STING pathway in microglia, MCN reprograms the neuroinflammatory microenvironment and robustly attenuates brain injury, leading to significant functional recovery. This work establishes a paradigm of transforming inherent bioactivity of natural products into targeted catalytic nanomedicines, offering a precise therapeutic strategy for mitochondrial-centric diseases.\n\nID: 42270221\nTitle: Orchestrating immunity and beyond: polysaccharides as multi-target regulators of inflammatory networks via gut microbiota and structure-dependent pathways.\nAbstract: Natural polysaccharides (NPs), as key bioactive constituents of many plants, have garnered significant attention due to their immunomodulatory properties and high safety profile. This review elucidates the molecular mechanisms underlying the immunomodulatory effects of NPs, their associated physiological outcomes, and the core structure-activity relationships. Mechanistically, NPs exert anti-inflammatory or immunostimulatory functions by modulating immune organ indices, activating or suppressing various immune cells (e.g., macrophages, dendritic cells, and NK cells), and regulating pivotal immune signaling pathways, including the TLR-NF-\u03baB/MAPK, JAK-STAT, and cGAS-STING pathways. Notably, NPs can indirectly modulate systemic inflammation by remodeling gut microbiota composition and its metabolites (e.g., short-chain fatty acids and tryptophan derivatives). In terms of applications, leveraging these immunomodulatory properties, NPs demonstrate considerable potential in maintaining intestinal homeostasis, ameliorating neuroinflammation-related disorders, exerting anti-cancer effects, and alleviating allergic diseases. Furthermore, this review examines the structural determinants of NPs' immunomodulatory potency, including molecular weight, monosaccharide composition (with a focus on mannose, arabinogalactans, and uronic acids), chemical modifications (such as acetylation, phosphorylation, and sulfation), and degree of branching. Finally, the review outlines the shortcomings of current research and suggests future research directions, proposing that future studies should shift from \"discovery and characterization\" to \"rational design and synthesis\".\n\nID: 42263678\nTitle: Epigenetic control of microglial mitochondrial immunity by KAT7 drives Alzheimer's disease pathogenesis.\nAbstract: Mitochondrial DNA (mtDNA)-driven innate immune signaling sustains chronic neuroinflammation in neurological diseases such as Alzheimer's disease (AD), yet how this pathway is regulated in microglia remains poorly understood. Here, we identify the histone acetyltransferase KAT7 (HBO1) as a central epigenetic regulator that links chromatin remodeling to mitochondrial immune activation. KAT7 and its histone mark H3K14ac are elevated in microglia from 5\u00d7FAD mice and human AD brains. Integrative transcriptomic and epigenomic analyses reveal that KAT7 activates transcription of cytidine/uridine monophosphate kinase 2 (Cmpk2), a mitochondrial kinase essential for mtDNA synthesis. Loss of KAT7 reduces Cmpk2 expression, impairs mtDNA replication and release, and consequently suppresses cyclic guanosine monophosphate-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NLRP3 signaling. Importantly, both microglia-specific deletion and pharmacological inhibition of KAT7 mitigate cytosolic mtDNA-induced neuroinflammation, decrease \u03b2-amyloid burden, restore synaptic plasticity, and improve cognitive function in 5\u00d7FAD mice. Together, these findings uncover an epigenetic-mitochondrial axis sustaining microglial pathogenicity and establish KAT7 as a potential therapeutic target for AD.\n\nID: 42263472\nTitle: Bifidobacterium pseudolongum alleviates chronic intermittent hypoxia-induced cognitive impairment by restoring acetate metabolism and suppressing hippocampal neuroinflammation and neuronal PANoptosis.\nAbstract: Obstructive sleep apnea, characterized by chronic intermittent hypoxia (CIH), is a common sleep disorder frequently accompanied by cognitive impairment. Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction. Targeting B.p and acetate may offer a promising therapeutic strategy for neuroprotection in OSA.\n\nID: 42258028\nTitle: Targeting inflammaging in Alzheimer's disease: molecular pathways and emerging pharmacotherapies.\nAbstract: Alzheimer's disease (AD), the leading cause of dementia, is intrinsically linked to the aging process. A central mechanism driving this association is inflammaging, a state of chronic, low-grade inflammation resulting from innate immune dysregulation. Emerging evidence suggests that inflammaging is not merely a background feature of aging but an active pathogenic driver of AD, accelerating amyloid-\u03b2 accumulation, tau hyperphosphorylation, and synaptic failure. This review synthesizes the molecular circuitry connecting inflammaging to AD, detailing the synergistic roles of the NLRP3 inflammasome, impaired autophagy, TREM2 signaling, and the cGAS-STING pathway. Furthermore, we critically evaluate pharmacological strategies designed to disrupt these cascades, including specific NLRP3 inhibitors, senolytic agents, and autophagy enhancers. We propose that these therapies offer a vital complementary approach to amyloid-targeting treatments, potentially modifying disease progression by extinguishing the persistent inflammatory milieu of the aging brain.\n\nID: 42254023\nTitle: Ferroptosis: an emerging key mechanism linking aging, surgical and anesthetic exposure to postoperative cognitive dysfunction.\nAbstract: Postoperative cognitive dysfunction (POCD) is a common complication in older surgical patients. While its pathogenesis remains unclear, ferroptosis-an iron-dependent form of cell death driven by lipid peroxidation-has emerged as a key mechanism in neurodegeneration. This review proposes that aging creates a ferroptosis-prone environment in the brain through iron dyshomeostasis, impaired antioxidant defenses, and enrichment of polyunsaturated fatty acids, and that surgical trauma and anesthetic exposure may trigger ferroptosis by activating interconnected pathways such as neuroinflammation, blood-brain barrier disruption, and oxidative stress, leading to neuronal injury in cognition-critical regions like the hippocampus. However, the available evidence is largely correlative, and whether ferroptosis acts as a proximal driver of neuronal death or as a late consequence of pre-existing damage remains undetermined. We dissect the core molecular machinery (GPX4, ACSL4, NCOA4, Nrf2) and emerging regulators (MD2/Hepcidin, CPT1A, RUNX1/RBM47/cGAS-STING, miRNAs, mitophagy, gut microbiota-exosome axis). Therapeutic strategies including iron chelators, lipophilic antioxidants, natural products, physical therapies, and nanomaterials are reviewed, but most remain preclinical. Elucidating the role of ferroptosis may open new avenues for early diagnosis, targeted prevention, and effective treatment, provided that causality can be rigorously established.\n\nID: 42254019\nTitle: Plasmacytoid dendritic cells in systemic and cutaneous lupus erythematosus: an evolving understanding.\nAbstract: Lupus erythematosus is a chronic, heterogenous autoimmune disease driven by a complex interplay of genetic, environmental and hormonal factors, which can manifest as systemic lupus erythematosus (SLE), cutaneous lupus erythematosus (CLE), or both simultaneously. Plasmacytoid dendritic cells (pDCs) are thought to play a central role in disease pathogenesis following the dysregulated and sustained production of type I interferon (IFN-I), leading to widespread immune system activation and chronic inflammation, resulting in organ and tissue damage characteristic of lupus. While treatment of lupus has shown success with approaches that inhibit the IFN pathway/IFN-I production, targeting pDCs is of great interest due to their accumulation in lesional tissues and key role in IFN-I production. However, SLE and CLE pathogenesis is clouded by unknowns including limited understanding of the pathophysiological loss of IFN pathway negative feedback, the complexity of IFN production by non-pDC cells (including pDC plasticity and role of different subsets/states), the role of other cytokines and chemokines in disease pathogenesis, and differences in pDC activation and downstream effects in SLE and CLE. Conceivably, different IFN-I-producing cells may be important in different organs, patients, and disease stages. As understanding of the role of pDCs in IFN-I production evolves, there is great potential to develop more targeted and effective treatments that can enhance patient outcomes to ensure pathophysiological and chronic inflammation is negated while maintaining physiological immunity to infection.\n\nID: 42252031\nTitle: Neuroprotection by lactate in Parkinson's disease: A novel anti-inflammatory mechanism via 14-3-3 protein lactylation.\nAbstract: Novel therapeutic strategies for Parkinson's disease (PD) are urgently needed. Neuroinflammation is a critical driver of disease progression and represents a promising target for intervention. Emerging evidence highlights lactate as a signaling metabolite that regulates inflammatory responses through protein lactylation. Given the involvement of 14-3-3 proteins in PD pathogenesis, we investigated whether lactate confers neuroprotection by promoting 14-3-3 lactylation and modulating neuroinflammatory signaling in PD. A rat model of PD was induced by subcutaneous injection of Rotenone (ROT) into the dorsal cervical region. Lactate was administered intracerebroventricularly. Motor function was assessed using open field, grid, and suspension tests. TH-positive neurons in the substantia nigra were evaluated by immunohistochemistry. The lactylation of 14-3-3 proteins and their interaction with NLRP3 were examined by co-immunoprecipitation (Co-IP). Mitochondrial localization of GSDMD was visualized by immunoelectron microscopy. The cytosolic mtDNA was assessed using qPCR. NLRP3 inflammasome components, the cGAS-STING pathway, and mitochondrial GSDMD were analyzed by western blotting. Levels of inflammatory cytokines and cGAMP were quantified by ELISA. Lactate ameliorated motor deficits and dopaminergic neuron loss in ROT-treated rats. Lactate increased 14-3-3 lactylation and enhanced 14-3-3 binding to NLRP3, accompanied by reduced NLRP3 inflammasome activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppressed cGAS-STING pathway activation. Lactate exerts neuroprotective effects in PD through a mechanism associated with enhanced 14-3-3 lactylation, reduced NLRP3/GSDMD pathway activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppression of cGAS-STING signaling.\n\nID: 42242586\nTitle: Early-onset neuroinflammation drives neurodegeneration caused by lysosomal PI(3,5)P2 insufficiency.\nAbstract: Phosphatidylinositol 3,5-bisphosphate [PI(3,5)P2] is a lysosomal signaling lipid whose deficiency, caused by mutations in the PIKfyve complex subunits FIG4 or VAC14, underlies a spectrum of fatal neurologic diseases including Charcot-Marie-Tooth type 4J (CMT4J) and amyotrophic lateral sclerosis (ALS). To map the molecular consequences of PI(3,5)P2 insufficiency in the brain, we performed quantitative proteomic and transcriptomic analyses of three mouse lines bearing distinct loss-of-function mutations in Fig4 or Vac14, examining the brain at the presymptomatic and end stages. Strikingly, profound neuroinflammation was already present at postnatal day 5 (before significant neurodegeneration), characterized by complement activation, interferon signaling, and parenchymal infiltration of peripheral myeloid cells and T-cells. Isolated mutant microglia exhibited a markedly pro-oxidative transcriptional state with elevated reactive oxygen species, a partly non-cell-autonomous phenotype, being present in microglia from mice with conditional Fig4 inactivation in just neurons and astrocytes. Comparison of early (P5) and late (P25) proteomics data revealed that PI(3,5)P2 insufficiency impairs developmental remodeling of the brain proteome: proteins typically upregulated during postnatal maturation failed to accumulate, implicating lysosomal function in neurodevelopment. We identify coordinated elevation of p53, Fas receptor, inflammatory caspases, Gasdermin D, RIPK1, and ZBP1, consistent with multifactorial inflammatory cell death with features of apoptosis, pyroptosis, and necroptosis. Many of the dysregulated proteins are encoded by genes mutated in lysosomal storage disorders, ALS, CMT, Alzheimer's and Parkinson diseases, extending the pathogenic relevance of PI(3,5)P2 insufficiency. Together, these findings establish that early neuroinflammation is a defining - and likely initiating - feature of neurodegeneration caused by disruption of lysosomal PI(3,5)P2.\n\nID: 42406597\nTitle: Protocol for isolation of live tumor-infiltrating immune cells from immunocompetent murine brains for high-dimensional profiling.\nAbstract: Here, we present an optimized workflow to isolate viable immune cells from tumor-bearing mouse brains, with particular emphasis on myeloid populations, to enable detailed functional analysis of the tumor-immune microenvironment. We describe steps for intracardiac perfusion and regional brain dissection. We then detail procedures for gentle enzymatic-mechanical dissociation, efficient myelin and red blood cell removal, and optional CD11b+ enrichment. This approach preserves immune cell viability and epitope diversity, supporting high-dimensional proteomic profiling via spectral flow cytometry and single-cell multi-omics.\n\nID: 42405451\nTitle: Susceptibility Source Separation Unveils Paramagnetic and Diamagnetic Trajectories in Healthy Brains From 5 to 90\u2009Years.\nAbstract: Susceptibility source separation (SSS) enables independent evaluation of both paramagnetic iron and diamagnetic myelin in the human brain. The aim of this work was to analyze healthy brain lifespan trajectories of paramagnetic and diamagnetic susceptibilities in deep gray matter (DGM) and white matter (WM) from a large database (339 subjects, 5 to 90\u2009years), all acquired at 3\u2009T on the same scanner, using \u03c7-separation and comparing it to two other common SSS methods (\u03c7-sepnet and APART-QSM). A 3D multiple echo gradient echo sequence was used to measure phase, R2* and QSM, as well as dual echo fast spin echo to measure R2. The mean value of WM and DGM regions was calculated for SSS output maps and plotted against age to evaluate trajectories across the lifespan. With \u03c7-separation, most DGM regions showed an increasing trend with age in the paramagnetic map, except for thalamus, which showed an inverted-U quadratic trajectory, and all DGM regions showed an increase in diamagnetic content with age. In WM, for the paramagnetic maps, body of corpus callosum, splenium and corticospinal tract showed an inverted quadratic trajectory, cingulum an increasing exponential, while no significant changes were seen in genu. For the diamagnetic WM maps, all regions followed a similar trajectory, increase in early life, peak around 40 to 60\u2009years, and decrease with age. The different SSS approaches yielded different curve shapes and mean values in many instances. For example, APART-QSM had consistently lower ppb values, \u03c7-sepnet had biologically unexpected results for early ages, and \u03c7-separation data had higher standard deviation of best-fit residuals when compared to the other evaluated methods for all analyzed regions and maps. All SSS methods enabled depiction of independent iron and myelin trends; however, different results between methods suggest caution in choosing SSS methods and the need for further methodological advances.\n\nID: 42404668\nTitle: RETRACTION: A Rare Case of Tumefactive Demyelination of Brain: A Case Report and Literature Review.\nAbstract: [This retracts the article DOI: 10.1002/ccr3.8369.].\n\nID: 42404389\nTitle: Transcutaneous electrical acupoint stimulation for intercostobrachial nerve syndrome after breast cancer surgery: a randomized controlled trial protocol.\nAbstract: Intercostobrachial nerve (ICBN) syndrome is a common peripheral sensory nerve injury following axillary surgery for breast cancer. It is characterized by persistent numbness and burning pain extending from the affected axilla to the medial aspect of the upper arm, as well as restricted shoulder joint mobility, which severely impacts postoperative recovery and quality of life. Current interventions primarily focus on symptomatic analgesia and functional exercises, lacking standardized external treatment protocols to promote nerve repair. Transcutaneous electrical acupoint stimulation (TEAS) combines the advantages of acupuncture and transcutaneous electrical stimulation. It is non-invasive and has high patient acceptance. Preliminary studies suggest it can promote axonal regeneration and myelin formation, yet scientific evidence-based evidence for ICBN syndrome is lacking. This study aims to systematically evaluate the therapeutic effects and safety of TEAS on ICBN syndrome through a prospective, randomized, sham-controlled trial, providing evidence-based medical evidence for clinical practice. This prospective, randomized, sham-controlled clinical trial will be conducted at the Yunnan Provincial Hospital of Traditional Chinese Medicine. We plan to recruit 200 patients with ICBN syndrome after breast cancer surgery. Participants will be randomly assigned in a 1:1 ratio to either the TEAS group or the Sham TEAS group, with 100 cases in each group. Both groups will start receiving treatment on the first postoperative day, administered once every other day. Ten sessions will constitute one course, for a total of three courses. The primary outcome measure is CMS. Secondary outcome measures include MMT, EMG, VAS, SWMT, FACT-B, SF-36, and TCM-SD. Adverse events will be recorded throughout the study. https://itmctr.ccebtcm.org.cn/mgt/project/view/2041939715654978881, identifier, ITMCTR2024000864.\n\nID: 42403632\nTitle: Effects of volatile anesthetics on peripheral nerve regeneration in a sciatic cut repair murine model.\nAbstract: We previously showed that 2% isoflurane conditioning promoted axonal and myelin regeneration leading to improved functional outcomes after peripheral nerve injury (PNI) in a sciatic nerve cut repair model. Whether the 1 MAC (minimum alveolar concentration) dose of isoflurane (1.2%) and other commonly used volatile anesthetics such as sevoflurane (2%), and desflurane (6%), support peripheral nerve regeneration is not known. The aim of the current study is to examine these possibilities in a rodent sciatic nerve injury model. Twelve-week-old male Lewis rats underwent sciatic nerve cut and repair and were divided into following groups. (1) control (no treatment), (2) isoflurane (1.2%), (3) sevoflurane (2%), and (4) desflurane (6%). Volatile anesthetic conditioning was achieved by administering isoflurane, sevoflurane, and desflurane for 1 h, beginning 1-h post sciatic nerve cut and repair, and the anesthetic exposure was repeated for the next two consecutive days for 1 h. Functional outcomes such as compound muscle action potential (CMAP), evoked muscle force (tetanic and specific tetanic force), wet muscle mass, and axonal counts were measured at 12 weeks post-surgery. A significant increase in the axonal numbers and myelin width was observed in the desflurane group. This was associated with the improvement in the specific tetanic force measured at 12 weeks post-surgery. Desflurane promoted axonal regeneration and myelination at 12 weeks post-peripheral nerve injury and repair in a murine model. Future experiments focusing on identifying the optimal dose to improve functional outcomes, and the molecular mechanisms underlying desflurane's potential protective effect are warranted.\n\nID: 42403013\nTitle: Fus-depleted oligodendrocytes reduce neuronal damage and Alzheimer's disease progression in the AppNL-G-F mouse.\nAbstract: Alzheimer's Disease (AD) is an age-dependent neurodegenerative disorder and represents the most common type of dementia, increasing in incidence at an alarming rate in the aging population. The hallmarks of the disease are amyloid plaque accumulation, microglia and astrocyte activation, and loss of presynaptic structure leading to cognitive decline. Recently, oligodendrocyte (OL) and myelin abnormalities have emerged as important contributors to the pathogenesis of AD. In normal brain homeostatic conditions, OL maintain neuronal health through myelin axon interactions and by supplying neurotrophic and metabolic support. How strengthening OL function may support neuronal health in AD neurodegeneration remains to be fully characterized and represents a gap in knowledge and a missed therapeutic opportunity. This study sought to examine how myelin and OL may improve neuronal deficits associated with AD. We have generated a novel mouse model (AD/cKO) by crossing the AppNL-G-F mouse, an established AD model, which carries three human AD mutations in the mouse App gene, with the FusOLcKO whose OL depleted of Fus (Fused in Sarcoma) produce thicker myelin associated with greater cholesterol biosynthesis. We evaluated spatial memory function with standardized cognitive testing. We evaluated microglia density and state, astrocytic activation and toxic phenotype, myelin density, cholesterol content, amyloid plaque burden, presynaptic structures, and neuronal hypoxic and oxidative damage in the hippocampus and cortex. We characterized the transcriptome of AD/cKO hippocampal OL compared to AD by using single-cell transcriptomic studies. Spatial working memory was fully preserved in the aged AD/cKO mouse relative to the AD mouse. This outcome was associated with reduced neuronal oxidative damage, preserved presynaptic structures at the amyloid plaque niches, and a shift in microglia state at the niches in both hippocampus and cortex. In contrast, amyloid plaque burden and microglia density were decreased in the hippocampus but not in cortex, uncoupling the neuronal and microglia effects from the amyloid burden. Fus dependent myelin increase was present in both hippocampus and cortex. Single-cell transcriptomics of AD/cKO hippocampal OL revealed upregulation of energy metabolism and antioxidant genes, suggesting a role of OL enhanced energy metabolism in mediating protection of neurons and affecting microglia state in AD pathology. This work provides new insight into how oligodendrocytes may protect neurons in AD, communicate with other glial cellular players, and point to potential targets for disease intervention aimed at slowing AD progression.\n\nID: 42402860\nTitle: Ferroptosis of microvascular pericytes contributes to ischemia-reperfusion injury in mice.\nAbstract: Ferroptosis is an iron-dependent form of programmed cell death implicated in various pathological conditions. We investigated whether ferroptosis contributes to acute ischemic stroke using a transient middle cerebral artery occlusion model in pial collateral-deficient CB-17/Icr-+/+Jcl mice. Mice were subjected to 90\u2009min of ischemia followed by reperfusion, and the effects of the ferroptosis inhibitor UAMC-3203 on infarct evolution and post-stroke histological changes were examined. UAMC-3203 increased the survival of CD13-positive pericytes within infarct areas and enhanced infarct reduction in the subacute phase. In vitro, the glutathione peroxidase 4 inhibitor RAS-selective lethal 3 (RSL3) induced dose-dependent cell death in pericytes but not in endothelial cells, which was suppressed by UAMC-3203 but not by inhibitors of apoptosis or necroptosis. RSL3 induced lipid peroxidation in pericytes, as evidenced by malondialdehyde accumulation. Extracellular ferrous iron (Fe2+), but not ferric iron (Fe3+) or transferrin, caused intracellular Fe2+ accumulation and cell death in pericytes, which was further enhanced by oxygen-glucose deprivation with reperfusion and suppressed by UAMC-3203. Myelin debris containing abundant Fe2+ induced ferroptosis in cultured pericytes. These findings indicate that pericytes are a major ferroptosis-vulnerable cell type during ischemia-reperfusion and may represent a therapeutic target in acute ischemic stroke.\n\nID: 42402732\nTitle: Alcohol-induced structural and cellular brain alterations: molecular and histopathological mechanisms.\nAbstract: Chronic alcohol consumption is a leading cause of acquired neurodegeneration with well-documented structural and ultrastructural brain alterations. This review analyzes the cellular and molecular mechanisms underlying alcohol neurotoxicity, integrating findings from animal models, human post-mortem studies, and neuroimaging investigations. Ethanol crosses the blood-brain barrier and generates toxic metabolites including acetaldehyde and reactive oxygen species, triggering oxidative stress, lipid peroxidation, and mitochondrial dysfunction. Chronic exposure induces glutamatergic and gamma-aminobutyric acid (GABA)ergic adaptations leading to excitotoxicity during withdrawal. Cell death occurs through apoptotic, necrotic, and necroptotic pathways, while microglial and astrocytic activation perpetuates neuroinflammation. Histopathological (HP) changes include selective neuronal loss in the prefrontal cortex, hippocampus, and cerebellum, dendritic simplification, and synaptic alterations. White matter pathology manifests as demyelination and axonal degeneration. Associated thiamine deficiency produces characteristic lesions in the mammillary bodies, thalamus, and cerebellar vermis. Neuroimaging techniques provide valuable HP correlates and biomarkers for disease monitoring. While some changes demonstrate partial reversibility with abstinence through remyelination and synaptic plasticity, extensive neuronal loss remains irreversible. Understanding these mechanisms is essential for developing neuroprotective therapeutic strategies.\n\nID: 42402307\nTitle: White matter abnormalities in Alzheimer's disease: Implications for pathophysiology, diagnosis, and treatment.\nAbstract: White matter (WM) abnormalities have emerged as a critical element in Alzheimer's disease (AD) pathogenesis, shifting from their former status as a passive consequence to an active contributor to disease progression. Notably, microstructural WM alterations, detectable early via advanced neuroimaging techniques such as diffusion tensor imaging, frequently precede overt gray matter atrophy and cognitive decline, highlighting their potential as early contributors to AD pathogenesis. The origins of WM pathology are multifactorial, involving a complex interplay among \u03b2-amyloid (A\u03b2) and tau aggregation, energy dysmetabolism, neuroinflammation, vascular dysfunction, and cellular senescence. Importantly, we emphasize a paradigm-shifting perspective: WM degeneration acts not merely as a downstream outcome but as a key driver of AD pathogenesis, capable of accelerating protein aggregation, amplifying neuroinflammation, and compromising neural plasticity. Given its early manifestation and close association with symptom onset, WM integrity has emerged as a sensitive and reliable biomarker for early AD detection and progression monitoring. Moving beyond diagnostics, the growing understanding of WM pathophysiology has unveiled a new frontier of therapeutic interventions aimed at myelin regeneration and WM protection. Despite persisting translational challenges, targeting WM integrity represents a pivotal avenue for developing disease-modifying therapies capable of slowing disease progression and improving clinical outcomes in patients with AD.\n\nID: 42402004\nTitle: Editorial for \"Association of Iron and Myelin Alterations in the Contralesional Dentate Nucleus and Thalamus With Functional Outcome in Acute Ischemic Stroke: A Susceptibility Source Separation Study\".\nAbstract: \n\nID: 42401664\nTitle: Evaluation of autophagy in neonatal rat glial cells in an in vitro model of hypoxic-ischemic injury.\nAbstract: The autophagy process is crucial for cell functioning, yet it is still understudied in glial cells during neurodevelopment. To address this, cultures of the main glial cell types in the central nervous system (CNS), including astrocytes, microglia, oligodendrocyte progenitors, and differentiating oligodendrocytes, were created to examine the impact of an in vitro hypoxia-ischemia (HI) model on autophagy. The HI insult was mimicked by applying temporal oxygen-glucose deprivation (OGD). Since neonatal hypoxic-ischemic insults primarily affect the brain's white matter, the study predominantly focused on oligodendrocytes at different stages of maturation: progenitor cells versus cells that express myelin components (e.g. MBP). The results show that the different glial fractions exhibit varying sensitivity to the applied conditions. Maturing oligodendrocytes were found to be more sensitive to OGD conditions than the progenitor fraction. The OGD procedure was proven to impact the expression of autophagy markers, indicating the activity of this process in response to injury. Western blot analysis of oligodendrocyte progenitor cells (OPCs) showed that the autophagy substrate marker p62 increased after six hours, which may suggest transient inhibition and subsequent activation of autophagy. To verify the involvement of autophagy in the differentiation of neonatal oligodendrocytes, the process was modulated using chloroquine (CQ) treatment. CQ is recognised as an inhibitor of autophagic flux because it disrupts lysosomal acidity and prevents the breakdown of autophagosomes. CQ treatment resulted in the accumulation of autophagosomes. The results suggest that abnormalities in the functioning of glial cells, particularly oligodendrocytes, in response to hypoxic-ischaemic (HI)-like conditions might be associated with altered autophagic flux in response to cellular stress. Transient alterations in autophagy were observed within 24\u00a0h of limiting oxygen and glucose supply, and these alterations may contribute to subsequent disorders in oligodendrocyte differentiation. This is recognised as one of the major issues in the pathogenesis of neonatal hypoxia-induced damage. Therefore, modulation of autophagy could be a promising therapeutic approach to prevent these adverse changes.\n\nID: 42401247\nTitle: Panax quinquefolius saponins promote remyelination via orchestrating HMGCS1-NPC1-MAL-mediated lipid metabolism and rebalancing JAK-STAT signaling in a cuprizone-induced demyelination model.\nAbstract: Panax quinquefolius L. is traditionally used as a \"Qi-tonifying and Yin-nourishing\" herb for weakness and limb flaccidity, symptoms described as \"Feng fei\" or flaccidity syndrome. These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.\n\nID: 42401006\nTitle: Spinal cord microglia exhibit a dysfunctional response to myelin damage.\nAbstract: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that affects both the brain and spinal cord, although the brain has historically received greater attention. In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair.\n\nID: 42400702\nTitle: The Potential of Rehabilitation to Amplify Experience-Induced Myelin Plasticity and Remyelination in Multiple Sclerosis: A Narrative Review.\nAbstract: This narrative review synthesizes emerging evidence on experience-dependent myelin plasticity and its relevance for neurorehabilitation in persons with multiple sclerosis (MS). Building on foundational work demonstrating motor learning-induced neuroplasticity, we highlight growing recognition that myelination remains adaptable across the lifespan and may be harnessed to support motor relearning, neuroprotection, and remyelination in MS. Preclinical and human studies demonstrate that neuronal activity, especially that induced by motor learning, regulates oligodendrocyte behavior and myelin remodeling. Rodent models show that skilled training enhances oligodendrocyte precursor cell proliferation and myelin thickness, while human neuroimaging confirms training-related increases in myelin-sensitive metrics within task-relevant systems. In MS, early evidence from exercise and motor training studies suggests task-specific white matter plasticity, though sample sizes remain small and imaging outcomes heterogeneous. Additional work points to synergistic potential between behavioral training, neuromodulation, and pharmacologic remyelinating agents. Notably, the combination of exercise and clemastine produces robust remyelination in preclinical models. With MS patients now living longer, aging introduces additional vulnerabilities-including inflammation, microglial dysfunction, and reduced regenerative capacity-but myelin retains responsiveness to behavioral and environmental enrichment. Experience-dependent myelin plasticity represents a promising but underexplored mechanism for enhancing neurorehabilitation outcomes. Motor learning, physical exercise, and multimodal interventions may support adaptive myelination, though optimized dosing, timing, and biomarkers remain undefined. Future research should employ targeted, multimodal imaging approaches and integrate behavioral, neuromodulatory, and pharmacologic strategies, in addition to following patients longitudinally post-intervention, to clarify the therapeutic potential of activity-driven remyelination.\n\nID: 42400220\nTitle: AQP4 and MOG Characterize the Autoantibody Landscape of Checkpoint Blockade-Induced Optic Neuritis.\nAbstract: The objective of this study was to investigate the autoantibody profile in immune checkpoint inhibitor (ICI)-induced optic neuritis (CBON) and identify key autoantibodies for diagnostic and therapeutic purposes. In this multicenter retrospective study (January 2020-June 2025), we screened 327 neuro-ophthalmic patients from a bio-repository of 2,321 ICI-treated individuals, identifying 88 patients with CBON across 3 independent cohorts (n\u2009=\u200925, 29, and 34). Longitudinal serum samples (pre-ICI, prodromal, onset, and follow-up) were available for 12 patients. A matched control group of 49 ICI-treated patients without neuro-ophthalmic symptoms was included. Serum samples were analyzed using cell-based assays for 25 neural-specific IgG autoantibodies. Longitudinal samples were assessed for antibody dynamics. Correlations between serostatus and clinical features were evaluated. Autoantibody profiling revealed a highly focused immune response concentrated against aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG). Seropositivity rates for these antibodies ranged from 17.3% to 32.4% across cohorts, whereas other neural antibodies were detected at markedly lower frequencies (<12%). Longitudinal analysis demonstrated a clear seroconversion pattern, with antibodies undetectable at pre-ICI baseline but emerging at symptom onset, which remained detectable during follow-up in a subset of patients. These AQP4/MOG antibodies were virtually absent in control patients (0-2%). This study establishes AQP4 and MOG as the dominant autoantibodies in CBON, providing a serological framework for diagnosis and classification. The persistent antibody response following ICI-induced seroconversion offers direction for future mechanistic investigations.

Human umbilical cord blood mononuclear cells (hUCB-MNCs) have shown neuroprotective and immunomodulatory properties; however, their therapeutic efficacy and underlying mechanisms in VaD remain incompletely understood. In this study, we investigated the effects of hUCB-MNCs treatment in a mouse model of VaD induced by bilateral common carotid artery stenosis (BCAS). Behavioral assessments showed that hUCB-MNCs treatment improved cognitive performance, affective-like behaviors, and motor coordination in BCAS mice. Histopathological analyses demonstrated that hUCB-MNCs treatment attenuated white matter injury, preserved myelin integrity, and mitigated neuronal and synaptic damage. Integrated transcriptomic and proteomic analyses of corpus callosum (CC) tissues revealed enrichment of immune-regulatory, phagocytosis-related, and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT)-associated pathways after hUCB-MNCs treatment. In vivo and in vitro analyses further indicated that hUCB-MNCs helped preserve microglial homeostatic features and improved myelin debris-handling responses. Collectively, these findings suggest that hUCB-MNCs ameliorate VaD-associated pathology, at least in part, by modulating microglial myelin debris-handling responses and PI3K/AKT-related signaling, highlighting hUCB-MNCs as a promising cell-based therapeutic candidate for VaD.\n\nID: 42399801\nTitle: Clinical risk factors for recurrence in adult-onset myelin oligodendrocyte glycoprotein antibody-associated optic neuritis.\nAbstract: Myelin oligodendrocyte glycoprotein antibody-associated optic neuritis (MOG-ON) is a subtype of demyelinating optic neuritis (ON) characterized by a considerable risk of relapse; however, the demographic and clinical factors associated with recurrence remain poorly defined, posing ongoing challenges for patient management. A retrospective analysis was conducted on adult-onset MOG-ON patients diagnosed in the Ophthalmology Department of the Chinese People's Liberation Army General Hospital (PLAGH) from January 2019 to January 2024. Patients were divided into two groups based on their experience of a relapse course: the relapsing group and the monophasic group. Multivariate analysis was performed to examine the effects of various clinical factors on the risk of recurrence. Among 126 screened participants, 56 were excluded. A total of 70 patients (median [IQR] age at onset, 35.50 [30.00, 48.75] years; 46 females [65.71%]) were included. During a median follow-up of 31.50 (IQR 21.25-52.75) months, disease relapse occurred in 54.29% (38/70) of patients. Multivariate analysis revealed that being female significantly elevated recurrence risk (hazard ratio [HR] 3.92, 95% CI 1.63-9.42, p\u2009=\u20090.002), while administration of immunosuppressive maintenance therapy after the first episode was associated with a lower likelihood of recurrence (HR 0.30, 95% CI 0.10-0.87, p\u2009=\u20090.026). At the final follow-up, the relapsing group had significantly worse visual outcomes compared with the monophasic group (median [IQR] VA, 0.40 [0.16-0.82] logMAR vs. 0.22 [0.10-0.40] logMAR; p\u2009=\u20090.012). In adult-onset MOG-ON, female sex is associated with an increased risk of recurrence, whereas early maintenance immunosuppressive therapy is associated with a lower recurrence risk. Furthermore, patients with a relapsing disease course exhibit poorer visual outcomes at follow-up compared with those with a monophasic course.\n\nID: 42399180\nTitle: Characteristics of Nerve Injury, Regeneration, and Vocal Fold Movement After Recurrent Laryngeal Nerve Electrocautery Injury.\nAbstract: To investigate the temporal patterns of regeneration and functional recovery following a unilateral recurrent laryngeal nerve (URLN) electrocautery injury. Unilateral recurrent laryngeal nerve\uff08RLN\uff09 injury rabbit models (n\u00a0=\u00a012) were established. At 2, 4, 8, and 12 weeks post-injury, RLN and neuromuscular junction\u00a0regeneration were evaluated via transmission electron microscopy\u00a0and immunofluorescence. Thyroarytenoid\u00a0muscle histopathology was assessed by hematoxylin and eosin\u00a0staining, and vocal fold (VF) movement was quantified via laryngoscopy. Correlation between neuroelectrophysiological changes and VF motion was analyzed in eight patients with RLN electrocautery injuries. At 2 weeks, myelin sheaths and synaptic membranes showed extensive disintegration. The single muscle fiber diameter (SMFD) decreased to 56.16%, the muscle fiber area ratio (MFAR) decreased to 40.35%, and the motion range ratio (MRR) decreased to 12.2%. At 4 weeks, the myelin lamellae continued to disintegrate with a small amount of regeneration. Regeneration of the presynaptic membrane (more than the postsynaptic membrane) began. MFAR was 46.86%, and MRR was 77.9%. At 8 weeks, the density of myelinated axon (DMA) peaked, but the axons and myelin sheath remained thin and immature. Postsynaptic membrane regeneration was significant, with partial overlap by the presynaptic membrane. MFAR rose to 58.59%, and MRR recovered to 96.9%. At 12 weeks, myelin sheaths thickened and matured despite a drop in DMA. Synaptic membrane number and morphology were normalized. SMFD and MFAR neared normal levels at 94.52% and 91.57%, respectively, and MRR recovered fully. 77.8% of patients exhibited partial or complete VF movement recovery. Despite causing initial injury, electrocautery may still permit sufficient axonal regeneration and subsequent muscle reinnervation to enable partial or complete recovery of VF movement.\n\nID: 42399024\nTitle: Post-Treatment Causes of Encephalopathy.\nAbstract: This article provides a comprehensive review of acute encephalopathic syndromes caused by multiple therapeutic medications, emphasizing their imaging features and underlying mechanisms. It covers chemotherapeutic-related acute encephalopathies such as acute toxic leukoencephalopathy, posterior reversible encephalopathy syndrome, and neurovascular complications of chemotherapy; immunotherapy-induced neurotoxicities including immunotherapy-associated encephalitis, aseptic meningitis, cranial neuropathies, demyelination, and hypophysitis; and chimeric antigen receptor T-cell therapy-related syndromes such as cytokine release syndrome, immune effector cell-associated neurotoxicity, and tumor inflammation-associated neurotoxicity. Toxicities from non-cancer medications-metronidazole, vigabatrin, and anti-amyloid monoclonal antibodies-are also discussed.\n\nID: 42398276\nTitle: Rising burden and future projections of multiple sclerosis in East Asia: Findings from the global burden of disease study 2021.\nAbstract: Multiple sclerosis (MS) is a chronic central nervous system disorder characterized by immune-mediated inflammation and demyelination. Although East Asia was historically regarded as a low-prevalence region, recent evidence suggests a rising MS burden, yet region-wide analyses of long-term trends and future projections remain limited. Using data from the Global Burden of Disease (GBD) 2021 study, we assessed MS burden in China, Japan, South Korea, North Korea, and Mongolia from 1990 to 2021. Age-standardized prevalence (ASPR), incidence (ASIR), mortality (ASMR), and disability-adjusted life years (DALYs) were analyzed, with temporal trends quantified using estimated annual percentage change (EAPC) and future burdens projected to 2041 through autoregressive integrated moving average (ARIMA) models. Between 1990 and 2021, ASPR in East Asia steadily increased, while ASDR declined. Mongolia consistently carried the highest burden, whereas China experienced the fastest growth, with ASPR projected to rise by more than 80% by 2041. Japan and South Korea showed relatively stable patterns, while North Korea exhibited moderate increases. Across all countries, females consistently bore higher burdens than men, and MS indicators were positively correlated with the Sociodemographic Index (SDI). Overall, the burden of MS in East Asia is increasing, with China projected to experience the steepest rise by 2041 and Mongolia continuing to carry a disproportionately high load. This study integrates long-term trends, cross-country comparisons, and gender-specific analyses to evaluate the burden of MS in East Asia, providing relevant evidence for formulating region-specific and gender-sensitive policies, enhancing preparedness, and strengthening health systems in East Asia to respond to the increasing burden of multiple sclerosis.\n\nID: 42398168\nTitle: YTHDF1 promotes myelin phagocytosis through m6A-dependent regulation of Galectin-3 to enhance macrophage glycolysis in painful diabetic neuropathy.\nAbstract: Painful diabetic neuropathy (PDN) represents a prevalent complication of diabetes, impacting sensory, motor, and autonomic nerves, with its pathogenesis remaining unclear, thereby hindering effective treatment. This study investigates the mechanisms underlying PDN and aims to identify potential molecular treatment targets. Male C57BL/6\u00a0J wild-type mice were employed to establish a PDN model, receiving intrathecal administration of shRNA targeting Galectin-3 (sh-Gal-3), shRNA targeting YTHDF1 (sh-YTHDF1), a YTHDF1 overexpression vector, or the m6A inhibitor 3-deazaadenosine (3-DAA), either individually or in combination. Macrophages underwent gene knockdown or overexpression and/or treatment with the glycolysis inhibitor 2-deoxy-d-glucose (2-DG) or 3-DAA. Diabetes was confirmed by monitoring blood glucose levels. Pain behavior was evaluated using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) assessments. Expression levels of Gal-3 and YTHDF1 were analyzed via Real-time PCR and Western blot, while myelin phagocytosis was evaluated through immunofluorescence and/or transmission electron microscopy. Glycolysis was assessed by measuring glucose uptake, lactate production, extracellular acidification rate (ECAR), and oxygen consumption rate (OCR). The RNA pull-down assay facilitated the detection of YTHDF1 binding to Gal-3 mRNA, and the half-life of Gal-3 mRNA was measured following transcription blockade using actinomycin D. Additionally, meRIP-qPCR assessed the m6A modification on Gal-3 mRNA. In vivo analyses revealed upregulation of Gal-3, which colocalized with IBA1. Silencing Gal-3 alleviated mechanical allodynia and diminished myelin phagocytosis. In vitro, Gal-3 silencing inhibited glycolysis, while Gal-3 overexpression enhanced myelin phagocytosis, an effect reversed by 2-DG treatment. Furthermore, high glucose stimulation elevated YTHDF1 expression, subsequently increasing Gal-3 levels; this induction was abrogated by YTHDF1 knockdown. Mechanistically, YTHDF1 enhanced Gal-3 mRNA stability through an m6A-dependent mechanism, promoting glycolysis and myelin phagocytosis. Consistently, YTHDF1 overexpression exacerbated PDN symptoms and myelin phagocytosis in vivo, which were mitigated by YTHDF1 knockdown or 3-DAA administration. YTHDF1 enhances Gal-3 mRNA stability and expression via an m6A-dependent mechanism, thereby facilitating glycolysis and myelin phagocytosis in PDN.\n\nID: 42398134\nTitle: FGF17 synergistically targets neuronal survival and oligodendrogenesis to restore stroke deficits.\nAbstract: Stroke remains a leading cause of long-term disability, and recovery is often limited by impaired neurorestoration and glial scar-mediated inhibition of axonal regeneration. Although fibroblast growth factor 17 (FGF17) regulates oligodendrocyte plasticity during aging, its therapeutic potential and underlying mechanisms in ischemic stroke remain unclear. We investigated whether FGF17 could promote functional recovery by enhancing neuronal restoration and overcoming glial scar-associated inhibition. Fgf17-positive cell distribution was mapped using Fgf17-reporter mice (Fgf17CreERT2/+;Rosa-CAG-LSL-tdTomato). Focal ischemia was induced in the motor cortex and anterior cingulate cortex of wild-type and Fgf17-deficient (Fgf17-/-) mice via photothrombosis. Recombinant FGF17 was administered intranasally. Functional recovery was evaluated using motor and cognitive behavioral tests. Mechanistic studies were performed using viral tracing, immunofluorescence, and molecular assays focusing on the extracellular signal-regulated kinase (Erk)-serum response factor (SRF) and phospholipase C gamma (PLC\u03b3)-cyclic adenosine monophosphate (cAMP) signaling pathways. FGF17 was predominantly expressed in neurons, whereas its receptor, fibroblast growth factor receptor 3 (FGFR3), was widely distributed. Fgf17-/- mice exhibited larger infarcts and more severe functional deficits, whereas intranasal FGF17 significantly improved motor and cognitive outcomes in both wild-type and knockout mice. Mechanistically, FGF17 promoted oligodendrogenesis and myelin repair by upregulating SRF through the Erk signaling pathway. Concurrently, FGF17 activated the PLC\u03b3-adenylyl cyclase axis, increased intracellular cAMP levels, and enabled axonal regeneration within the inhibitory microenvironment through downregulation of mRNA levels of oligodendrocyte myelin glycoprotein, neurite outgrowth inhibitor A, and myelin-associated glycoprotein. In addition, FGF17 enhanced neuronal survival and preserved dendritic spines via the PI3K-Akt pathway. Overall, FGF17 promotes oligodendrogenesis and enhances the intrinsic regenerative capacity of neurons. These findings identify FGF17 signaling as a promising therapeutic target for neurorestoration after stroke.\n\nID: 42397737\nTitle: STING-dependent peripheral inflammaging drives neurodegeneration via extracellular vesicles.\nAbstract: All animals age. However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration.\n\nID: 42397532\nTitle: Spatiotemporal profiling of white matter lesions and their contribution in the pathologies of Parkinson's disease animal models.\nAbstract: Increasing evidence has identified significant white matter lesions (WMLs) in Parkinson's disease (PD) patients. However, the complex relationships between WMLs and the neuropathological changes of PD remain unclear. In this study, we comprehensively elucidated the spatiotemporal dynamics of WMLs in rotenone-, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD models, and \u03b1-synuclein (\u03b1-Syn) (A53T) transgenic mice. The results showed that WMLs occurred across multiple brain regions and gradually aggravated as PD models progressed. Notably, WMLs emerged as early pathological events of PD prior to dopaminergic neuronal loss. Consistently, WMLs-related axial movement disorders, including gait and balance impairments, preceded those caused by nigrostriatal injury. Further in vitro studies revealed that oligodendrocyte precursor cells (OPCs) dysfunction caused by 1-methyl-4-phenylpyridinium (MPP\u207a) or \u03b1-Syn could induce dopaminergic axonal breakage and neuronal damage, confirming myelination disorder promoted dopaminergic neuronal degeneration. This finding was certified in additional in vivo studies using lysophosphatidylcholine (LPC)-induced demyelination models. The results validated that WMLs could independently induce dopaminergic neuronal damage and nigrostriatal pathway-related movement disorders. Moreover, comorbid WMLs in PD mice further aggravated this process. In summary, our findings uncovered the spatiotemporal characteristics of WMLs and their contribution to PD pathological development, highlighting that targeting WMLs might be a potential strategy for PD intervention.\n\nID: 42396941\nTitle: Anti-MAG Polyneuropathy: Characterization of the Monoclonal Gammopathy and Clonal B-Cell Population.\nAbstract: Polyneuropathy due to antibodies to myelin-associated glycoprotein (MAG) is a rare disease with an estimated prevalence of 1 per 100,000. Symptoms start in the sixth or seventh decade of life, presenting sensory polyneuropathy with sensory ataxia, paresthesia, mild motor deficit, and tremor of upper extremities. The neurophysiological features are compatible with length-dependent demyelination. It is caused by monoclonal gammopathy of the IgM type produced by clonal B cells. In recent years the monoclonal anti-CD20 antibody has become the preferred first-line treatment, but with limited efficacy. We identified a cohort of 42 patients diagnosed with anti-MAG polyneuropathy. Clinical data were collected retrospectively, and flow cytometry files and immune histochemistry slides were reassessed. We report that in most cases of anti-MAG polyneuropathy, the monoclonal IgM is kappa-restricted, the B-cell population shows lymphoplasmacytic differentiation, MYD88L265P mutation is a frequent finding, and the clonal B-cell population includes plasma cells. These findings most likely explain the low efficacy of rituximab monotherapy. We found the burden of symptoms to be high among patients with anti-MAG polyneuropathy as most of our patients had received intravenous immunoglobulin infusions and/or B-cell-directed treatment. We suggest that future treatment protocols for anti-MAG polyneuropathy should incorporate plasma cell-directed drugs. Furthermore, we found complement receptor 1 (CD35) to be down regulated on clonal B lymphocytes but not on normal B lymphocytes in these patients. We suggest that this may be a common feature of clonal B lymphocytes in chronic lymphoproliferative diseases.\n\nID: 42396559\nTitle: Myelin development in the peripheral nervous system of Trachemys scripta.\nAbstract: Myelin is one of the most important features of the vertebrate nervous system, formed by glial cells. In the peripheral nervous system, Schwann cells produce myelin. While much is known about the molecules and processes involved in mammalian myelination, little is known about it in other vertebrate groups. In this study, we examined myelin development in the peripheral nerves of the turtle Trachemys scripta using qPCR, RNA sequencing, immunofluorescence, and TEM. Our findings indicate that in T. scripta, myelination begins during the late stages of embryonic development and continues beyond hatching. Expression profiles reveal both conservation and divergence of core myelination components between mammals and amphibians; however, direct gene-level comparisons across species require further investigation given our small sample size. The upregulation of orthologous myelin genes in the turtle PNS supports the idea that these components are conserved, although their timing, regulation, or network structure may differ across tetrapods. We based our inference of conservation on orthology and the coordinated expression of key myelin genes (e.g., ErbB2, Mag, Mpz, Mbp, Pmp22) in T. scripta. TEM analysis of turtle sciatic nerves shows myelin rings in a few axons starting at stage 21, increasing significantly by stage 24, and becoming prominent in most axons of the adult nerve. Furthermore, antibodies against MPZ, DRP2, and Kv1.1 indicate that T. scripta adult peripheral nerves at various axial levels contain myelin segments with structures consistent with appositions and Schmidt-Lanterman incisures. Overall, this is the first study of PNS myelin development in a reptile, demonstrating that myelination is a highly conserved process in vertebrates.\n\nID: 42395866\nTitle: The role of SUMOylation in regulating proteins that drive neuronal disease progression.\nAbstract: SUMOylation is a post-translational modification in which a Small Ubiquitin-like Modifier (SUMO) protein is reversibly attached to a lysine residue on a target protein in an ATP-dependent process. This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders.\n\nID: 42395502\nTitle: Distinct Hippocampal Cellular Pathologies Influence Cognition Across Diagnostic Categories, Also Distinguishing Schizophrenia from Affective Psychoses.\nAbstract: Total and social cognition deficits independently predict functioning in psychosis, but targeting these in clinical trials are unsuccessful in improving function. The admixture of schizophrenia and affective psychoses cases could be a roadblock if these differ in cellular pathology. We examined cognitive functioning (MATRICS) and hippocampal cellular pathologies based on metabolite biomarker concentrations ( 1 H-MRSI), using categorical and transdiagnostic classifications in 80 participants: 22 non-psychotic affective disorder (NP-aff), 25 healthy controls (HC), and 33 with psychosis (Psy), including 20 schizophrenia and 13 affective psychoses (aff-P) cases. NP-aff and HC had similar total cognition (46.64\u00b112.01 vs 41.10\u00b117.88), both superior to Psy (28.34\u00b112.34; p's<0.01). Mean metabolite concentrations were similar across all groups but showed significant within-group associations to cognitive tests. For HC, total cognition, working memory and reasoning deficits were associated with reduced neuronal integrity (-.414, -.422, -.433, p's<.05), although no biomarker predicted total cognition in the clinical groups. For NP-aff, elevated myelin/membrane concentrations accompanied cognitive deficits; significantly so for visual learning deficits (.446, p<.05), which were also associated with decreased glia (-.503, p<.05). Opposite NP-aff, reduced myelin/membrane concentrations predicted cognitive deficits in Psy (-.514, p<.05). Separating schizophrenia from aff-P on social cognition showed reduced glutamate/excitation in schizophrenia (-.673, p<.05) but higher myelin/membrane turnover and neuronal integrity concentrations in aff-P (.575, .581, p's<.05). Schizophrenia and affective psychosis significantly differed for biomarkers of cellular pathology related to social cognition. Distinctly different underpinnings for cognition were also identified for other groups, aligning with DSM-5 and ICD disorder based categories. These findings include support for heterogeneous, but not transdiagnostic, conceptualizations of cognition and psychosis.\n\nID: 42394357\nTitle: Characterizing Combined Central and Peripheral Demyelination-Insights From a Multimodal Comparison With Chronic Inflammatory Demyelinating Polyneuropathy and Multiple Sclerosis.\nAbstract: Combined central and peripheral demyelination (CCPD) is a rare dysimmune disorder sharing features with multiple sclerosis (MS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Direct comparisons of central and peripheral diagnostic findings across these entities remain limited. We, therefore, performed a systematic study assessing nervous system involvement in CCPD, using magnetic resonance imaging (MRI), nerve ultrasound (US), and nerve conduction study (NCS) and compared findings to MS and CIDP controls. We conducted a descriptive case study including 4 CCPD patients, 13 CIDP patients, and 10 MS controls. All subjects underwent a standardized protocol of NCS and US. In addition, MS and CCPD patients also underwent brain and spinal cord MRI. Cerebrospinal fluid testing was performed in 20/27 patients. NCS revealed electrodiagnostic features suggestive of demyelination in all CCPD and CIDP patients, fulfilling the electrodiagnostic criteria for CIDP. We found motor conduction abnormalities in two MS patients, not fulfilling criteria for demyelination. US showed a similar pattern of multifocal nerve enlargement in CCPD and CIDP patients, while three MS patients also demonstrated mild proximal median nerve enlargement. Finally, CSF oligoclonal bands were only found in MS patients. Peripheral diagnostic tools reveal strikingly similar electrophysiological and morphologic features in CCPD and CIDP, underscoring a potential overlap in their disease mechanisms and the challenges of distinguishing these entities based on peripheral nerve assessment alone. Our findings further suggest that US could serve as a potentially useful screening tool in patients with predominantly central nervous system demyelinating syndromes and suspected peripheral involvement, helping to guide subsequent electrophysiological testing.\n\nID: 42394260\nTitle: Therapeutic potential of liver X receptor agonist GW3965 in preserving myelin integrity following traumatic brain injury.\nAbstract: Myelin, a multilamellar sheath produced by oligodendrocytes, ensures rapid electrical impulse conduction and maintains axonal integrity in the central nervous system (CNS). Demyelination, the loss or disruption of this protective sheath, is a key pathological consequence of traumatic brain injury (TBI) that exacerbates axonal injury and ultimately contributes to persistent cognitive and motor deficits. Currently, no therapies specifically target demyelination after TBI. Liver X receptors (LXRs) regulate lipid metabolism, cholesterol homeostasis, and inflammation in CNS cells. Activation of LXRs promotes oligodendrocyte maturation, enhances myelin gene expression, and facilitates remyelination. We hypothesized that GW3965, a synthetic LXR agonist, would enhance myelination and improved cognitive outcomes after TBI. C57BL/6 mice were subjected to mild TBI using a closed-head injury model and treated orally with GW3965 (10\u00a0mg\u00b7kg-1\u00b7day-1) starting 1\u2009day post-injury for 3\u2009weeks. Cognitive and behavioural performance was assessed using the modified Neurological Severity Score, open-field, novel object recognition, and Y-maze tests. On day 28 post-TBI, cortical tissues were analysed by immunofluorescence and a ProteinSimple\u00ae capillary-based immunoassay. TBI caused sustained neurological and cognitive impairments characterized by demyelination, axonal injury, and neuronal loss. GW3965 treatment significantly preserved mature oligodendrocytes and myelin, reduced axonal degeneration, and improved behavioural performance. This study provides novel insights into the role of LXR activation via GW3965 in mitigating TBI-induced demyelination and axonal injury, while preserving mature oligodendrocytes and cognitive and behavioural outcomes. These findings advance our understanding of brain repair mechanisms and highlight LXR activation as a promising therapeutic strategy for TBI-related neurological damage.\n\nID: 42393898\nTitle: Heterocyclic Scaffolds as Therapeutic Agents in Multiple Sclerosis: Mechanisms and SAR Study.\nAbstract: Multiple sclerosis (MS) is a progressive, immune-mediated condition characterized by the destruction of myelin, the protective insulation surrounding nerve fibers. This ongoing assault triggers a cascade of damage, including persistent inflammatory responses, loss of myelinproducing oligodendrocytes, axonal degradation, and cumulative neurological impairment. While motor and sensory difficulties are hallmark features, patients frequently contend with less visible but equally debilitating symptoms such as cognitive dysfunction, profound fatigue, affective disorders, nerve pain, and autonomic instability. These often-overlooked manifestations critically impact well-being and functional capacity. The pathophysiology of MS is increasingly understood as a network of overlapping cellular and molecular dysfunctions. Alongside irregularities in the endocannabinoid signaling network, key contributors include aberrant immune communication, persistently activated microglia, impaired mitochondrial energy production, and dysregulated activity of enzymes like PDE7, MAGL, ROCK, and PADs. These interconnected pathways collectively drive disease initiation and advancement. This analysis synthesizes established information on current FDA-approved treatments for MS and examines promising novel small-molecule compounds aimed at specific disease-relevant targets. A significant focus is placed on medicinal chemistry advancements, particularly the design and optimization of heterocyclic compounds. Scaffolds incorporating quinolines, pyrimidines, indoles, and related nitrogen-containing structures demonstrate considerable potential for conferring immunomodulation, reducing inflammation, and protecting neural tissue. By evaluating structure-activity relationships, binding mechanisms, and strategic drug design, this review offers an integrated perspective to inform the creation of new, targeted therapies for MS.\n\nID: 42393438\nTitle: Association of Iron and Myelin Alterations in the Contralesional Dentate Nucleus and Thalamus With Functional Outcome in Acute Ischemic Stroke: A Susceptibility Source Separation Study.\nAbstract: Susceptibility alterations in deep gray matter (DGM) nuclei after acute ischemic stroke (AIS) may relate to impaired functional independence. However, conventional quantitative susceptibility mapping (QSM) cannot separate paramagnetic iron-related from diamagnetic myelin-related sources, potentially obscuring relevant pathophysiological alterations. To apply \u03c7-separation to disentangle paramagnetic susceptibility (\u03c7para) and diamagnetic susceptibility (\u03c7dia) in DGM nuclei after AIS and assess associations with 3-month functional independence. Prospective. 82 AIS patients (52\u2009M/30 F) and 82 healthy controls (49\u2009M/33 F). 3\u2009T; 3D multi-echo gradient-echo sequence for QSM and \u03c7-separation reconstruction. \u03c7para and \u03c7dia were measured in the caudate, putamen, globus pallidus, substantia nigra, red nucleus, thalamus, and dentate nucleus. Contralesional nuclei were analyzed in patients. Group differences and 3-month outcome associations were assessed. Functional independence was defined as modified Rankin Scale score 0-2, and poor outcome as 3-6. Linear mixed-effects models, analysis of covariance, logistic regression, receiver operating characteristic analysis; p\u2009<\u20090.05 was significant. Compared with healthy controls, patients showed higher \u03c7para in all seven nuclei, including the dentate nucleus (84.065\u2009\u00b1\u200915.086 vs. 76.172\u2009\u00b1\u200911.387\u2009ppb) and thalamus (30.633 [28.036, 34.454] vs. 28.867 [26.749, 31.804] ppb), and higher \u03c7dia in the caudate, putamen, red nucleus, thalamus, and dentate nucleus (dentate nucleus: -18.916\u2009\u00b1\u20096.496 vs. -22.220\u2009\u00b1\u20095.002\u2009ppb). Poor 3-month outcome was independently associated with higher dentate nucleus \u03c7para (OR, 1.07; 95% CI, 1.03-1.11), higher dentate nucleus \u03c7dia (OR, 1.14; 95% CI, 1.04-1.26), and higher thalamus \u03c7para (OR, 1.22; 95% CI, 1.08-1.38). The combined model, incorporating conventional model factors (age, sex, stroke subtype, NIHSS score, and infarct volume) and \u03c7-separation metrics, outperformed the conventional model (AUC, 0.862 vs. 0.757). \u03c7-separation revealed iron- and myelin-related susceptibility alterations in contralesional DGM nuclei after AIS. Susceptibility metrics in the dentate nucleus and thalamus were associated with poor 3-month functional outcome. 2. Stage 1. Stroke recovery may depend not only on the visible infarct lesion, but also on distant brain regions related to functional independence. Quantitative susceptibility mapping can detect tissue susceptibility alterations, but cannot separate iron\u2010related and myelin\u2010related sources, which may obscure pathophysiological changes relevant to poor recovery. The researchers used \u03c7\u2010separation to assess these sources in contralesional deep gray matter nuclei, meaning nuclei opposite the infarct lesion, after acute ischemic stroke. Alterations in the dentate nucleus and thalamus were associated with poorer independence after 3\u2009months, helping clarify remote brain changes during recovery.\n\nID: 42404903\nTitle: Cholinergic regulation of neuroinflammation: linking microglia, immunometabolism, and neuromodulation.\nAbstract: Neuroinflammation is increasingly recognized as a core pathological process in various neurological diseases, including neurodegenerative disorders, stroke, autoimmune demyelinating diseases, and acute brain dysfunction associated with systemic inflammation. Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42404434\nTitle: Inflammatory alterations mediate tau-associated neurodegeneration.\nAbstract: Microglia monitor and respond to the brain's microenvironment to maintain homeostasis. However, in Alzheimer's disease and related dementias, chronically pro-inflammatory microglia may contribute to pathology. We hypothesized that inflammatory alterations, measured as microglia density via 18\u2005kDa translocator PET, would be elevated with a topography similar to tau, be most strongly associated with tau compared to amyloid and neurodegeneration, and mediate pathways among amyloid, tau and neurodegeneration. Participants (21 cognitively unimpaired, 25 cognitively impaired) from the Longitudinal Imaging of Microglial Activation in Different Clinical Variants of Alzheimer's Disease study underwent baseline amyloid PET (Florbetaben standard uptake value ratio), tau PET (MK6240 standard uptake value ratio), 18\u2005kDa translocator PET (ER176 standard uptake value ratio) and structural MRI (grey matter volume). Biomarkers were quantified in 13 a priori regions of interest. Cognitive assessments and consensus diagnoses were performed at the Columbia Alzheimer's Disease Research Center with biomarker information when available to define cognitive impairment. We evaluated cross-sectional regional colocalization of microglia density and amyloid, tau and neurodegeneration biomarker elevations in cognitively impaired individuals compared to amyloid-negative cognitively unimpaired individuals, microglia density associations with amyloid, tau and neurodegeneration biomarkers and microglia density mediation pathways among amyloid, tau and neurodegeneration. Exploratory analyses were stratified by amyloid positivity. Across all cognitively impaired individuals with different underlying brain microenvironments to which microglia are sensitive, higher microglia density colocalized with greater tau (10 regions) more often than with amyloid (8 regions) and neurodegeneration (4 regions), was associated with greater tau (\u03b2 = 0.29-0.67 in cingulate, lingual and parietal regions) and neurodegeneration (\u03b2 = -3.6 to -0.14 in limbic and medial temporal regions), and mediated tau-associated neurodegeneration (\u03b2 = -0.44 to -0.26 in limbic, temporal and parietal regions). In the context of amyloid-positivity, microglia may also mediate amyloid-associated tau (\u03b2 = 0.24-0.25 in parietal regions) and tau spreading (\u03b2 = 0.09-0.12 across progressive Braak stage regions), whereas amyloid may not be necessary for tau-associated neurodegeneration, particularly in limbic regions (\u03b2 = -0.46 to -0.37 in amyloid-negative individuals with cognitive impairment alone). Glia may represent a promising target for intervening on tau-associated neurodegeneration across individuals with cognitive impairment.\n\nID: 42404111\nTitle: Didymin mitigates neuroinflammation and preserves blood-brain barrier integrity after subarachnoid hemorrhage.\nAbstract: Subarachnoid hemorrhage (SAH) is a highly lethal and disabling type of stroke. The main causes of poor prognosis are neuroinflammation, blood-brain barrier (BBB) disruption and brain edema following hemorrhage. Didymin has shown neuroprotective effects in intracerebral hemorrhage; however, its regulatory role in SAH remains unclear. The rat SAH model was established using the internal carotid artery puncture method, while an in vitro model was developed by stimulating human brain microvascular endothelial cells (HBMECs) with hemoglobin (Hb). Following didymin treatment, neurological functional outcomes were assessed using the modified Garcia score and the balance beam test. Nissl staining was performed to evaluate neuronal pathological changes. Immunofluorescence staining was employed to assess microglial activation and BBB integrity. Brain water content was measured to evaluate the severity of cerebral edema. Western blot analysis was utilized to detect the expression of matrix metalloproteinase 9 (MMP9), apoptosis-related proteins (Bcl-XL, Bcl-2, Bax), pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and tight junction proteins (ZO-1, Occludin). Didymin treatment significantly improved neurological function scores in SAH rats by alleviating neuronal damage and apoptosis. On one hand, didymin reduced post-SAH neuroinflammation by inhibiting excessive microglial activation and the expression of pro-inflammatory cytokines. On the other hand, didymin preserved BBB integrity and alleviated brain edema by downregulating MMP9 expression. In Hb-induced cell model, didymin suppressed MMP9 expression and promoted the expression of tight junction proteins. In this study, we demonstrated that didymin mitigates neuronal damage and apoptosis following SAH, effectively suppresses neuroinflammation, maintains the integrity of the BBB, and attenuates brain edema. These findings suggest that didymin holds promise as a potential therapeutic candidate for the treatment of SAH.\n\nID: 42403363\nTitle: Roles of Microglia in Cerebral Small Vessel Disease.\nAbstract: Cerebral small vessel disease (CSVD) is a major cause of vascular dementia, characterized by heterogeneous pathologies affecting the brain's microvasculature. In recent years, researchers have recognized the significant role of neuroinflammation and increased permeability of the blood-brain barrier (BBB) in the development of CSVD. Within this framework, microglia exert multifaceted roles. This review synthesizes current evidence on microglial involvement in CSVD, covering their heterogeneity, associations with neuroimaging markers, pathogenic mechanisms, and the translational prospects of microglia-directed therapies. Chronic cerebral hypoperfusion drives microglial activation toward pro-inflammatory phenotypes, triggering oxidative stress, inflammatory mediator release, and BBB disruption. These pathological changes correlate spatially with white matter hyperintensities, enlarged perivascular spaces, and lacunes. Microglia also interact with other glial cells to modulate disease progression. Preclinical studies have shown that modulating microglial phenotypes can be beneficial, though clinical translation remains challenging. Microglia serve as pivotal double-edged players, central to both neuroinflammation and BBB dysfunction in CSVD.Understanding the intricate relationship between microglia and CSVD is essential for elucidating the underlying mechanisms and paves the way for novel therapeutic approaches.\n\nID: 42403147\nTitle: Tangeretin ameliorates sepsis-induced neurocognitive impairment in adult male mice by suppressing Akt-driven glycolytic reprogramming and neuroinflammation.\nAbstract: Sepsis, a life-threatening organ dysfunction caused by a dysregulated host response to infection, frequently leads to long-term cognitive impairment. Tangeretin, a polymethoxylated citrus flavonoid, has neuroactive and anti-inflammatory properties. We investigated whether tangeretin protects against sepsis-associated neurocognitive deficits and delineated the underlying mechanisms, focusing on Akt signalling and microglial metabolism. Sepsis was induced by caecal ligation and puncture in mice. Tangeretin (15 or 30\u2009mg\u00b7kg-1\u00b7day-1, intraperitoneal) was initiated immediately after surgery and maintained throughout the study. Cognitive function was assessed by Morris water maze and novel object recognition. Hippocampal microglial activation and neuroinflammation were quantified. In vitro, BV2 cells and primary microglia were exposed to lipopolysaccharide (LPS, 1\u00a0\u03bcg\u00b7ml-1) with/without tangeretin (40\u2009\u03bcM) to measure cytokine production, migration and Akt activity. Direct tangeretin-Akt interaction was tested by surface plasmon resonance and cellular thermal shift assay. Metabolic readouts focused on glycolysis. Tangeretin improved sepsis-induced cognitive deficits, decreased hippocampal microglial activation, and lowered proinflammatory cytokine levels and microglial migration. It exerted anti-inflammatory effects via inhibition of the Akt pathway, and pharmacological Akt activation blocked these effects. Surface plasmon resonance and cellular thermal shift assay showed hat tangeretin binds Akt. Metabolically, tangeretin reduced LPS-induced glycolysis (decreased extracellular acidification rate and glycolytic capacity), consistent with diminished Akt phosphorylation and microglial activation. Tangeretin mitigates sepsis-associated neuroinflammation and cognitive impairment by targeting microglial Akt signalling and restraining glycolytic reprogramming. These data support tangeretin as a mechanistically informed candidate for adjunctive therapy in sepsis-related neurocognitive dysfunction.\n\nID: 42401768\nTitle: Pharmacokinetics of Fentanyl and Norfentanyl in a Rat Model of Fixed-Volume Hemorrhagic Shock.\nAbstract: Hemorrhagic shock (HS) remains a leading cause of trauma-related mortality, primarily due to severe hypovolemia and systemic hypoperfusion. These pathophysiological changes may profoundly affect the pharmacokinetics of fentanyl, an opioid widely used for analgesia in trauma care. Previous studies, predominantly based on fixed-pressure shock models, may not adequately reflect clinically relevant hemodynamic conditions. Therefore, we employed a fixed-volume HS model as an alternative approach to reflect hypovolemia-associated perfusion deficits influencing fentanyl disposition. This study aimed to evaluate the pharmacokinetics of fentanyl and its primary metabolite, norfentanyl, in an experimental model of fixed-volume HS. Male Wistar rats were randomly divided into two groups: a control group (C; n\u00a0=\u00a06) and a fixed-volume hemorrhagic shock group (HS; n\u00a0=\u00a06). In the HS group, hemorrhage was induced by withdrawal of 30% of the estimated blood volume (EBV) following vascular cannulation. Fentanyl (10\u00a0\u00b5g/kg) was administered intravenously, and serial blood samples were collected over 60\u00a0min. The concentrations of plasma fentanyl and norfentanyl were determined by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Pharmacokinetic parameters were calculated using Phoenix WinNonlin software. Non-compartmental analysis demonstrated significantly increased systemic exposure to fentanyl in the HS group, reflected by higher area under the concentration-time curve (AUC0-\u221e and AUC0-t) values, accompanied by a marked reduction in systemic clearance (CL). Mean residence time (MRT) and terminal elimination half-life (t\u00bd\u03bbz) were significantly prolonged. Compartmental analysis confirmed a more than two-fold increase in fentanyl exposure, driven primarily by reduced clearance and prolonged elimination. In contrast, peak plasma concentrations (Cmax) showed only a borderline increase, and no statistically significant differences were detected in distribution-related parameters. These findings suggest that the major detectable pharmacokinetic changes associated with HS were primarily related to impaired fentanyl elimination. The metabolic conversion ratio (MCR), defined as the ratio of norfentanyl\u00a0AUC0-t to fentanyl\u00a0AUC0-t, was lower in the HS group (0.117) compared with controls (0.197). HS significantly alters fentanyl pharmacokinetics in rats by reducing clearance and increasing systemic exposure. The lower norfentanyl-to-fentanyl AUC0-t ratio suggests that HS may also affect metabolite formation or disposition.\n\nID: 42401313\nTitle: Chronic stress primes TLR3-mediated systemic inflammation to produce persistent post-viral fatigue syndrome-like symptoms in mice.\nAbstract: This study examined the long-term effects of polyinosinic:polycytidylic acid (poly I:C), a synthetic double-stranded RNA and Toll-like receptor 3 (TLR3) agonist, on behavioral and immune outcomes in chronically stressed mice. Male C57BL/6J mice were exposed to 21\u202fdays of wet bedding stress followed by a poly I:C injection. Post viral fatigue syndrome (PVFS)-like symptoms were evaluated over 7\u202fdays post-injection using grip strength testing, the forced swim test, von Frey filament testing, the Morris water maze, the open field test, and the social interaction test. Body temperature and locomotor activity were continuously monitored via intraperitoneally implanted dataloggers. Serum concentrations of interleukin-6 (IL-6), IL-10, and C-X-C motif chemokine ligand 10 (CXCL10) were quantified. In separate cohorts, minocycline (a microglial activation inhibitor) or RU486 (a glucocorticoid receptor antagonist) was administered prior to poly I:C injection. Following IP injection of poly I:C, body temperatures in both stressed and unstressed mice were significantly elevated, indicating a polyphasic febrile response. At 7\u202fdays post-injection, stressed mice treated with poly I:C exhibited persistent fatigue, mechanical allodynia, depressive-like behavior, impaired spatial memory, increased anxiety-like behavior, and reduced social interaction. Serum levels of IL-6 and CXCL10 remained elevated and correlated with behavioral outcomes. Pretreatment with minocycline partially attenuated both the behavioral and immune responses, whereas RU486 pretreatment did not. These findings demonstrate that TLR3-mediated systemic inflammation induced by poly I:C produces persistent, multi-domain PVFS-like symptoms in chronically stressed mice. The attenuation by minocycline implicates neuroinflammation as a possible mechanism.\n\nID: 42400090\nTitle: Study protocol: double-blind, randomized, prospective, placebo controlled parallel group phase II study to investigate the effect of glycerol phenylbutyrate (GPB) on neurofilament light chain (NfL) levels in patients with corticobasal syndrome (CBS).\nAbstract: Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disorder, with no disease-modifying treatments currently available. The most common underlying pathology is a 4-repeat tauopathy. Neurofilament light chain (NfL) is a biomarker of neuronal damage and has shown potential as a measure of disease progression. Glycerol phenylbutyrate (GPB), a prodrug of phenylbutyric acid, has demonstrated potential neuroprotective properties in preclinical studies on tauopathies. This phase II clinical trial will investigate the effects of GPB on NfL levels in CBS patients. The primary objective is to assess the efficacy of GPB in reducing NfL levels over 26\u00a0weeks compared to placebo as well as safety and tolerability of GPB. Secondary objectives include evaluating changes in clinical scales. This is an investigator-initiated double-blind, randomized, placebo-controlled, parallel-group phase II clinical trial, performed in two German university hospitals. A total of 32 patients with CBS will be enrolled and randomized to receive either GPB or placebo. The primary outcome is the change in NfL levels between baseline and 26\u00a0weeks as well as safety and tolerability of GPB. Secondary outcomes are changes in clinical scores. Exploratory analyses involve pharmacokinetics, changes in the metabolomic, proteomic and lipidomic profiles and imaging outcomes, such as MRI and microglia-PET. The study protocol has been approved by the lead ethics committee at LMU Munich and conforms to the ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines. If successful, this clinical trial could identify a novel therapeutic approach for slowing disease progression in CBS, contributing to a broader understanding of GPB's therapeutic potential. The clinical trial has been registered in ClinicalTrials.gov (NCT05983588) and due to Transition in the Clinical Trials Information System (CTIS; EUCT No. 2024-516897-31-00, date of transition: 2024-09-26).\n\nID: 42399983\nTitle: Regional mapping of CSF1R-positive microglia in neurodegenerative diseases and progressive MS, with exploratory presynaptic marker analyses.\nAbstract: Microglial colony-stimulating factor-1 receptor (CSF1R) is a therapeutic and imaging target, yet the regional, disease-specific distribution of CSF1R-positive microglia in the human brain remains incompletely defined, limiting interpretation of emerging CSF1R-PET signals. We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers. A cross\u2011disease, region\u2011resolved map reveals region\u2011specific changes in CSF1R\u2009+\u2009cell density in neurodegeneration, but only white matter in MS. These findings provide the histological context needed to interpret future CSF1R\u2011PET. Prospective studies pairing CSF1R\u2011PET with SV2A\u2011PET and multiplex tissue profiling are warranted to define microglial states and synaptic outcomes in vivo.\n\nID: 42399626\nTitle: Neuroinflammation and depression: immune-brain interface mechanisms, biomarker stratification, and therapeutic strategies.\nAbstract: Major depressive disorder is among the most prevalent and disabling conditions in global medicine, yet its biological underpinnings remain incompletely understood, and current pharmacological treatments fail to produce adequate responses in approximately one-third of patients. A rapidly accumulating body of evidence has not simply challenged the long-dominant monoamine deficiency hypothesis but has provided a mechanistic framework that may explain many of the observed monoaminergic alterations in depressive cohorts, including IDO1-driven serotonin depletion, cytokine-mediated AMPA receptor internalization, and HPA-immune feedback dysregulation. Neuroinflammation, particularly glial activation across microglial, astrocytic, and oligodendrocyte lineages, and its downstream consequences for tryptophan metabolism, glutamatergic transmission, synaptic plasticity, and neurotrophic signaling, represents a central pathophysiological mechanism in a substantial subgroup of depressed patients. Peripheral inflammatory markers, including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha, are elevated in a significant proportion of individuals with major depressive disorder, and these elevations predict poor response to conventional antidepressants while identifying patients who may respond preferentially to anti-inflammatory strategies. Post-mortem studies, positron emission tomography imaging of translocator protein density, and transcriptomic analyses of brain tissue have collectively provided consistent, though not yet fully definitive, evidence that microglial activation is a neurobiological feature of depression rather than a consequence of comorbid physical illness. This review synthesizes current mechanistic understanding of the neuroinflammatory hypothesis of depression, examines the evidence base from epidemiological, biomarker, neuroimaging, and interventional studies, including null findings and methodological limitations, evaluates emerging therapeutic strategies targeting the immune-brain interface, and identifies the critical questions that will determine whether immunopsychiatry fulfills its promise as a precision medicine framework for treatment-resistant depression.\n\nID: 42397694\nTitle: Border-Associated Macrophages in CNS Health and Disease: A Comprehensive Review of Ontogeny, Heterogeneity, and Functional Plasticity at Neural Interfaces.\nAbstract: Border-associated macrophages (BAMs) represent a specialized population of tissue-resident immune cells strategically positioned at the critical interfaces between the central nervous system (CNS) and peripheral circulation, including the meninges, choroid plexus, and perivascular spaces. As frontline sentinels of the neuroimmune system, BAMs perform essential functions in immune surveillance, barrier integrity maintenance, and homeostatic regulation, yet their unique biology and disease-associated roles remain incompletely characterized compared to parenchymal microglia. This review aims to synthesize current knowledge on BAM ontogenetic origins, compartment-specific heterogeneity, transcriptional programs, and functional outputs in both health and neurological disorders. We conducted a comprehensive literature analysis integrating findings from lineage tracing studies, single-cell RNA sequencing, spatial transcriptomics, and functional interrogation in animal models of disease. The results reveal that BAMs exhibit remarkable cellular diversity shaped by distinct ontogenetic origins-primarily yolk sac-derived erythro-myeloid progenitors with variable contributions from fetal liver and postnatal monocytes depending on anatomical compartment. Compartment-specific marker combinations (CD206, LYVE1, CD163, MHCII) define functionally distinct subsets, and core transcriptional regulators including PU.1 and IRF8 maintain BAM identity while CSF-1/IL-34-CSF1R signaling governs survival and renewal. In neurological disorders including ischemic stroke, Alzheimer's disease, multiple sclerosis, and brain tumors, BAMs display pronounced double-edged roles, transitioning from protective homeostatic guardians to pathogenic drivers depending on disease stage and microenvironmental context. This comprehensive analysis establishes a unified framework for understanding BAM biology and identifies critical opportunities for developing subset-specific therapeutic strategies targeting these interface macrophages in neurological diseases.\n\nID: 42397162\nTitle: Spinal 5-HT1A Receptor-Related and Microglial Mechanisms Associated With Intrathecal Cannabidiol-Induced Antinociception in Neuropathic Pain.\nAbstract: Although first-line pharmacological treatments for neuropathic pain are often ineffective, cannabidiol has shown promise. However, the analgesic effects of orally administered, cannabidiol are limited by low bioavailability and a short half-life. Therefore, this study investigated the effects of intrathecal (i.t.), cannabidiol administration on neuropathic pain, focusing on spinal 5-HT1A receptors and microglial modulation. Male C57BL/6 mice were subjected to neuropathic pain-induced by chronic constriction injury (CCI). Mechanical nociceptive thresholds were assessed using von Frey filaments. The involvement of spinal 5-HT1A receptors was examined by i.t. administration of the selective antagonist WAY-100635. mRNA expression, IL-10, and TNF-\u03b1 levels, and microglial activation were evaluated. Intrathecal, cannabidiol significantly reversed mechanical allodynia, producing a more potent and prolonged antinociceptive effect than oral administration. This effect was abolished by WAY-100635, indicating spinal 5-HT1A receptor involvement. Moreover, i.t. cannabidiol increased spinal IL-10 levels and 5-HT1A receptor mRNA expression, while reducing microglial activation. In vitro, cannabidiol attenuated microglial activation and significantly reduced TNF-\u03b1 production. In conclusion, i.t. cannabidiol effectively alleviates neuropathic pain in mice, with findings that may suggest the involvement of spinal mechanisms associated with 5-HT1A receptor-related signaling and modulation of microglial activation.\n\nID: 42395461\nTitle: Microglia-Specific Molecular Magnetic Resonance Imaging Probe Enables Noninvasive Separation of Parkinsonian Mice from Controls.\nAbstract: Neuroinflammation mediated by reactive microgliosis is a central driver of Parkinson's disease (PD) pathogenesis. This inflammatory process unfolds years before clinical symptoms, creating an opportunity for early intervention. In vivo imaging technologies that could detect and quantify microglial reactivity are therefore essential for early diagnosis, patient stratification, and evaluating emerging immunomodulatory therapies that target this fundamental driver of PD progression. Yet no standardized, sensitive, and specific technology currently achieves this goal. Molecular magnetic resonance imaging (mMRI) is uniquely suitable to address this problem because it integrates inherent high spatial resolution and soft-tissue contrast of conventional MRI with molecularly targeted contrast agents, enabling simultaneous acquisition of anatomical detail and functional/biological information at submillimeter isotropic resolution. Here we present a novel mMRI probe designed to specifically target colony stimulating factor-1 receptor, expressed primarily on microglia in the brain. In silico data show that the targeting ligand binds the extracellular Ig domain of the receptor. In vitro cell uptake studies with both murine and human microglia cell lines show that the probe binds the receptor triggering active cell uptake and in vivo MRI enabled effective separation of the A53T mouse model of Parkinson's disease from control mice using radiomics-assisted MR image analysis. Ex-vivo immunohistochemical analysis showed signal from the probe largely in the cytosolic compartment of IBA-1 reactive cells, confirming that the observed in vivo MRI signal is due primarily to retention of the agent by microglia. This novel technology has the potential to interrogate the rgional presentation of microglial activation in PD. A microglia targeted MRI probe generates disease-specific contrast after injection, clearly distinguishing A53T Parkinsonian mice from controls.\n\nID: 42394930\nTitle: Brain cell-released Cyclophilin A induces neuroinflammation and exacerbates blood-brain barrier injury in acute ischemic stroke.\nAbstract: Excessive neuroinflammation mediates blood-brain barrier (BBB) disruption and poor outcomes after acute ischemic stroke (AIS). Cyclophilin A (CypA), when released into the extracellular space (designated as eCypA), may participate in inflammatory reactions and vascular dysfunction. However, its role in regulating neuroinflammation and BBB injury in AIS, as well as the therapeutic potential of targeting eCypA remain unclear. ELISA was used to detect eCypA release in serum from 22 AIS patients (17 mild, 5 severe; 13 males, 9 females; mild: age 65.41\u202f\u00b1\u202f10.20\u202fyears, NIHSS 2.88\u202f\u00b1\u202f1.45; severe: age 64.00\u202f\u00b1\u202f5.04\u202fyears, NIHSS 9.40\u202f\u00b1\u202f3.29; blood sampled within 48\u202fh of onset), in serum/cerebrospinal fluid (CSF) from transient middle cerebral artery occlusion (tMCAO) rats, and in supernatants from BV2 (microglia) or bEnd.3 (brain microvascular endothelial cells) exposed to oxygen-glucose deprivation/reoxygenation (OGD/R) or lipopolysaccharide (LPS). Nine-week-old male Sprague-Dawley rats (n =\u202f5 per group) underwent 1.5\u202fh of tMCAO via the intraluminal suture method followed by 24\u202fh of reperfusion before sampling. These rats received intracerebroventricular injection of cyclophilin A-binding heptameric peptide (C46) before tMCAO establishment. Cerebral infarct volume was measured via TTC staining. BBB permeability was assessed by Evans blue extravasation. Western blot was employed to determine protein levels of tight junction (TJ) proteins, matrix metalloproteinases (MMPs) and proinflammatory mediators. Microglial activation was evaluated by immunofluorescence. eCypA levels were significantly elevated in AIS patient serum (1.74\u202f\u00b1\u202f0.23\u202fng/mL in mild, 2.39\u202f\u00b1\u202f0.09\u202fng/mL in severe vs. 1.30\u202f\u00b1\u202f0.19\u202fng/mL in healthy controls, p <\u202f0.001), in tMCAO rat serum (2.57\u202f\u00b1\u202f0.14 vs. 1.62\u202f\u00b1\u202f0.07\u202fng/mL, p <\u202f0.001) and CSF (2.14\u202f\u00b1\u202f0.23 vs. 1.47\u202f\u00b1\u202f0.19\u202fng/mL, p <\u202f0.001), as well as in the supernatants of OGD/R-challenged BV2 (0.92\u202f\u00b1\u202f0.01 vs. 0.55\u202f\u00b1\u202f0.03\u202fng/mL, p <\u202f0.001) and bEnd.3 cells (1.10\u202f\u00b1\u202f0.05 vs. 0.52\u202f\u00b1\u202f0.03\u202fng/mL, p <\u202f0.001) and LPS-induced BV2 cells (1.12\u202f\u00b1\u202f0.08 vs. 0.56\u202f\u00b1\u202f0.13\u202fng/mL, p <\u202f0.001) compared with their respective control groups. The eCypA inhibitory peptide C46 effectively improved neurological function, reduced cerebral infarct volume and edema in tMCAO rats. Moreover, C46 mitigated BBB permeability, preserved the expression levels of TJ proteins, and suppressed the activation of MMPs in tMCAO rats and OGD/R-treated bEnd.3 cells. Meanwhile, C46 administration inhibited microglial activation and downregulated the expression of proinflammatory mediators both in vivo (tMCAO rats) and in vitro (OGD/R- or LPS-induced BV2 microglia). eCypA, released by microglia and brain microvascular endothelial cells under ischemic-hypoxic and inflammatory conditions, serves as a critical pathogenic mediator that drives neuroinflammation and BBB disruption in AIS. Targeting eCypA with C46 peptide effectively abrogates these pathological cascades, thereby supporting eCypA as a novel therapeutic target for AIS.\n\nID: 42393340\nTitle: OTUB1 non-canonically inhibits TAB2 ubiquitination to govern microglia-mediated neuroinflammation.\nAbstract: Microglia contribute to detrimental neuroinflammation under pathological conditions and thereby drive the pathogenesis and development of various diseases of the central nervous system (CNS). Here, the deubiquitinating enzyme OTUB1 is identified as a regulator of microglial activation and CNS inflammation. In mice, microglia-specific OTUB1 deletion significantly ameliorates ischemic brain injury by reducing the pro-inflammatory activation of microglia. OTUB1 enhances Toll-like receptor (TLR) signaling through stabilizing UBC13 and TAB2, leading to the increased induction of cytokines. Notably, OTUB1 reduces the proteasomal degradation of TAB2 by reducing its K48 ubiquitination in a catalytic activity-independent manner. Moreover, microglia-confined OTUB1 deficiency also alleviates lipopolysaccharide-induced sickness behavior and experimental autoimmune encephalomyelitis in mice due to decreased neuroinflammation. Pharmacological inhibition of OTUB1 significantly mitigated ischemic stroke injury in mice. These findings reveal an important role of OTUB1 in potentiating microglial activation and neuroinflammation, providing a proof-of-principle observation for targeting OTUB1 in the treatment of TLR-associated neuroinflammatory diseases.\n\nID: 42392741\nTitle: [Dihydroartemisinin ameliorates inflammation in experimental autoimmune encephalomyelitis by enhancing AXL signaling in microglia].\nAbstract: This study aimed to investigate the mechanism of dihydroartemisinin(DHA) in ameliorating multiple sclerosis(MS). Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.\n\nID: 42392258\nTitle: Ablation of microglial estrogen receptor alpha predisposes male mice to diet-induced obesity.\nAbstract: Estrogen receptor alpha (ER\u03b1) signaling has metabolic and anti-inflammatory properties in addition to its impact on reproductive function. Compared to females, male mice generally exhibit greater inflammatory activation of microglia and increased susceptibility to diet-induced obesity (DIO). Given the established metabolic protective effects of estrogen, these observations raise the possibility that sex differences in microglial estrogen signaling contribute to this sexual dimorphism. In this study, we assessed metabolic and CNS histopathological properties in a mouse model with inducible microglia-specific ablation of ER\u03b1 (MG-ER\u03b1KO). Male MG-ER\u03b1KO mice developed increased weight gain and insulin resistance relative to controls during high-fat diet (HFD) feeding. Indirect calorimetry and food intake analysis revealed that reduced energy expenditure, coupled with an inadequate compensatory reduction in food intake, was the primary driver of the obese phenotype. In contrast, female MG-ER\u03b1KO mice fed HFD developed mild insulin resistance, with no change in body weight gain compared to controls, despite a similar reduction in energy expenditure. Immunohistochemical analyses of the microglial activation marker IBA1 in the mediobasal hypothalamus (MBH) revealed that female MG-ER\u03b1KO mice had an increased number of microglia without showing morphological signs of activation. In contrast, MBH microglial number was unchanged in MG-ER\u03b1KO male mice, but the cells adopted more activated morphological profiles. Finally, HFD-fed MG-ER\u03b1KO male mice had increased POMC neuron-microglia interactions but fewer overall hypothalamic POMC neurons, suggesting microglia may disrupt POMC neuron integrity to promote DIO. Together, these findings indicate that sex-specific actions of estrogen in microglia limit the metabolic complications of HFD feeding.\n\nID: 42392131\nTitle: Interferon-\u03b1 as a precision medicine tool in Sj\u00f6gren's disease: a cohort and experimental medicine study.\nAbstract: Mechanistic heterogeneity is a major obstacle to the development of effective treatment for Sj\u00f6gren's disease, and there is a pressing need to stratify Sj\u00f6gren's disease according to precision medicine principles. Aberrant activation of the type 1 interferon (IFN) pathway represents a leading candidate pathway, but a causal role of elevated IFN\u03b1 in driving Sj\u00f6gren's disease has yet to be established. We aimed to examine the role of IFN\u03b1 in driving a Sj\u00f6gren's disease endotype and relevance to precision medicine principles. We used data from the UK Primary Sj\u00f6gren's Syndrome Registry (UKPSSR), a multicentre observational cohort of participants with Sj\u00f6gren's disease, and UK Biobank, a large population-based cohort which includes people with and without Sj\u00f6gren's disease, to study the role of IFN\u03b1 in Sj\u00f6gren's disease. Ultrasensitive single molecule ELISA and an oligoprotein IFN signature score derived from broad capture proteomics were used to analyse samples from UKPSSR and data from the UK Biobank Pharma Proteomics Project (a subset of individuals from UK Biobank) to establish the timecourse and immune endotype associated with elevated IFN\u03b1. To address causality, we created a new transgenic mouse model of IFN\u03b1 overexpression to establish whether chronically elevated IFN\u03b1 drives this immune endotype. People with lived experience of Sj\u00f6gren's disease were involved in the design of the UKPSSR and shaping of research questions. Between Aug 1, 2009, and March 31, 2012, we identified 177 people with Sj\u00f6gren's disease in UKPSSR (mean age 57\u00b75 years [IQR 46\u00b70-65\u00b70], 163 [92%] women, 14 [8%] men, and 162 [92%] White ethnicity). In addition, between March 13, 2006, to Oct 1, 2010, we identified 47\u2008606 people without Sj\u00f6gren's disease and 257 people with Sj\u00f6gren's disease in the UK Biobank Pharma Proteomics Project, including 137 individuals sampled before diagnosis. IFN\u03b1 concentrations were elevated in 108 (61%) of 177 people with Sj\u00f6gren's disease in the UKPSSR. Oligoprotein IFN signatures were detected up to 14 years before diagnosis of Sj\u00f6gren's disease in the UK Biobank Pharma Proteomics Project. Individuals in UKPSSR with elevated IFN\u03b1 had a distinct immunological endotype characterised by cytopenia, hypergammaglobulinaemia, multiple autoantibodies, and autoimmunity against the Sj\u00f6gren autoantigen TRIM21/Ro52. In a mouse model of systemic chronic IFN\u03b1 elevation, in which IFN\u03b14 was overexpressed by conventional dendritic cells, the key features of the endotype were recapitulated and could be partly reversed by type 1 interferon receptor (IFNAR1) blockade. We found that the elevation of IFN\u03b1 drives an immune endotype of Sj\u00f6gren's disease, and elevated IFN\u03b1 can be detected over a decade before diagnosis. People with Sj\u00f6gren's disease with elevated IFN\u03b1 concentrations were broadly clinically similar to those with normal IFN\u03b1 concentrations, yet were immunologically distinct. This highlights the mechanistic heterogeneity of Sj\u00f6gren's disease and the need for immunological stratification along precision medicine principles, using high resolution biomarkers. In addition to demonstrating causal direction, biological modelling in a mouse model showed that chronic IFN\u03b1 elevation over the lifecourse had the potential to establish persistent immune dysregulation, which responded only partly to IFNAR1 blockade. These findings provide insights into Sj\u00f6gren's disease and other interferonopathic rheumatological disorders.

Due to shared pathological mechanisms between AD and diabetes, antidiabetic drugs like sodium-glucose cotransporter-2 inhibitors (SGLT2is) are potential therapeutic options. Although SGLT2is have shown cognitive benefits in diabetes models, their effects in AD models are not fully established. This study aimed to evaluate the therapeutic effects of sotagliflozin (Sota), an SGLT2i, in both in vivo and in vitro AD models. The network pharmacology analysis was used to predict the potential targets and pathways of Sota. And we selected 6-month-old APP/PS1 transgenic mice to investigate the effects of Sota. Cognitive function was assessed using the Morris water maze test. Immunohistochemistry and immunofluorescence were employed to quantify amyloid-beta (A\u03b2) plaque deposition in the hippocampal or cortex and analyze neuronal loss. Additionally, amyloid \u03b2 oligomers induction and microglial cells were used to evaluate the effects of Sota on the release of pro-inflammatory mediators and to investigate the underlying mechanisms. In vivo, Sota treatment improved cognitive impairments, reduced pro-inflammatory cytokines, inhibited microglial activation, and promoted neuronal survival. In vitro, Sota mitigated A\u00df oligomer-induced toxicity in microglial cells by decreasing reactive oxygen species and pro-inflammatory cytokine release. Mechanistically, Sota treatment was associated with suppression of extracellular signal-regulated kinase (ERK) signaling. Our findings suggest that Sota improved cognitive impairment and attenuates neuroinflammation in AD. Sota may be a promising candidate for the treatment of AD.\n\nID: 42391876\nTitle: CIRBP mediates hypoxia-induced mitochondrial metabolic reprogramming in microglia to regulate polarization and anxiety-like behavior.\nAbstract: Exposure to high-altitude hypoxia can lead to anxiety-like behaviors, social issues, and other dysfunctions of the central nervous system (CNS), but the molecular mechanisms behind these effects are not fully understood. Microglial M1 polarization and changes in mitochondrial metabolism are crucial in hypoxic brain injury. The cold-inducible RNA-binding protein (CIRBP) is known to regulate mitochondrial balance and inflammatory responses. However, its role in hypoxia-induced microglial metabolic changes, polarization issues, and anxiety-like behaviors is still unclear. This study established an in vivo mouse model of high-altitude hypoxia, an in vitro hypoxic injury model of BV2 microglia, and an in vitro neuronal intervention model with microglia-derived conditioned medium. Integrating in vivo and in vitro experimental designs, we further systematically elucidated the potential molecular mechanisms underlying hypoxic brain injury. Findings indicated that high-altitude hypoxic exposure led to anxiety-like behaviors, social dysfunction, and neuronal and synaptic damage in the hippocampal CA1 region of mice. Hypoxia first triggered mitochondrial metabolic reprogramming in microglia, characterized by inhibition of oxidative phosphorylation, decreased ATP production, and accumulation of reactive oxygen species (ROS) and lactate, which subsequently drove the conversion to the M1 pro-inflammatory phenotype. Inhibition of microglial activation by minocycline significantly reversed hypoxia-induced synaptic damage. At the molecular level, hypoxia downregulated CIRBP expression in microglia. Overexpression of CIRBP in microglia ameliorated mitochondrial metabolic dysfunction and regulated microglial polarization, while knockdown of CIRBP in microglia exacerbated these abnormalities. Targeted overexpression of CIRBP in microglia within the hippocampal CA1 region significantly attenuated hypoxia-induced neuronal damage and behavioral abnormalities. This study elucidates a novel mechanism by which CIRBP in microglia mediates hypoxic brain injury, offering a potential therapeutic target for neuropsychiatric disorders associated with high-altitude hypoxia.\n\nID: 42389758\nTitle: Limitations of Current Therapies and Barriers in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) remains a major global health crisis due to its complex pathophysiology and limited therapeutic effectiveness. Despite advances in understanding key mechanisms such as amyloid-beta accumulation, tau pathology and neuroinflammation, current therapies provide limited clinical benefit. Multiple factors contribute to limitations and highlight the difficulty of translating scientific advancements into meaningful improvement in patient outcomes. This article provides a comprehensive and critical review of therapeutic, biological, clinical, and systemic barriers to effective Alzheimer's disease management as well as showcasing emerging strategies aimed to improve early detection, treatment approaches, and overall disease prevention.\n\nID: 42389350\nTitle: Infiltrating monocytes augment alternative complement activation and exacerbate inherited retinal degeneration in a mouse model.\nAbstract: In retinal degenerative disease, microglia and macrophages accumulate at sites of pathology and strongly influence disease progression, yet their distinct contributions remain unclear. To define the fate and function of infiltrating monocyte-derived macrophages (MDM) in retinal degeneration, we generated a CCR2-CreER mouse line on the rd10 background to enable precise monocyte-specific tracking and ablation. Infiltrating monocytes rapidly downregulated CCR2 and LY6C upon entering the retina and acquired de novo TMEM119 and P2RY12 expression, together with a ramified, microglia-like morphology. Immunohistochemistry and transcriptomic profiling showed that a subset of these cells was cleared by resident microglia. Microglia-monocyte interactions enhanced M\u00fcller cell C3 production, whereas activated microglia increased CFB and decreased CFH expression, thereby promoting complement alternative pathway activation. Selective ablation of infiltrating monocytes reduced microglial activation and phagocytosis, suppressed M\u00fcller cell C3 expression and complement deposition, lowered proinflammatory cytokine levels, and ultimately ameliorated photoreceptor degeneration. These findings identify infiltrating monocytes as key drivers of immune dysregulation and proinflammation, highlighting them as potential targets for neuroprotective therapy.\n\nID: 42388793\nTitle: Extracellular vesicles from wild-type Epstein-Barr virus-transformed B-cells export host DNA and EBV EBER1.\nAbstract: Epstein-Barr virus (EBV) infection is nearly ubiquitous and strongly linked to multiple sclerosis (MS), but how EBV-infected B cells communicate with distal tissues remains unclear. We performed an integrated multiomic characterization of small extracellular vesicles (sEVs) released from spontaneous lymphoblastoid cell lines (SLCLs) derived from healthy donors and patients with MS, transformed ex vivo by endogenous wild-type EBV. Proteomics identified over 6,000 shared proteins enriched in nucleic acid-binding and chromatin-associated factors. EV-associated DNA resolved into two structurally distinct compartments: DNase-sensitive, high-molecular weight DNA associated with the vesicle corona and DNase-resistant, nucleosome-sized (\u223c130-150 bp) DNA. Both compartments were overwhelmingly host-derived and broadly genomically distributed, whereas EBV DNA was minimal. In contrast, viral RNA cargo was dominated by the EBV noncoding RNA EBER1, which was strikingly enriched across all lines and confirmed within individual vesicles by ddPCR and super-resolution microscopy. EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency, pointing to EV-mediated export of EBER1 as a candidate mechanism linking peripheral EBV infection to distal tissue signaling in MS and beyond.\n\nID: 42387307\nTitle: Baseline Neuroinflammation Stratifies TSPO-PET Response to Disease-Modifying Therapy in Multiple Sclerosis.\nAbstract: To investigate which baseline clinical and imaging characteristics best predict TSPO-PET-measurable reduction in glial activation following treatment of multiple sclerosis (MS), to utilize this information for designing more efficient biomarker-based clinical trials targeting glial activation. This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS.\n\nID: 42387204\nTitle: Microglial tunneling nanotubes: an intercellular transfer facilitating mitochondrial dysfunction and neuroinflammation in experimental cerebral malaria.\nAbstract: Cerebral malaria (CM), the most severe neurological manifestation of Plasmodium infection, is characterized by microglial activation that plays a pivotal role in initiating pathogenic neuroinflammatory cascades. Tunneling nanotubes (TNTs) are dynamic F-actin-based intercellular connections which transfer mitochondria and pathogenic factors. Although TNTs have been implicated in various neuropathological conditions, their precise involvement in CM pathogenesis, particularly in relation to microglial activation, remains undefined. In this study, single-cell RNA-sequencing (scRNA-seq) revealed significant dysregulation of TNT-associated genes and actin cytoskeleton pathway remodeling in microglia of ECM model. In vitro studies demonstrated that Plasmodium-infected red blood cells (pRBCs)-stimulated primary microglia formed extensive F-actin-rich tunneling nanotubes, which mediated the bidirectional transfer for mitochondria and facilitated intercellular trafficking of lysosomal contents and malarial pigment. These TNT-mediated intercellular communication amplified microglial activation, as evidenced by: (i) lipid peroxidation, (ii) mitochondrial dysfunction, and (iii) autophagosome (LC3+) accumulation. This process further amplifies neuroinflammation through TNF\u03b1/IL-6 secretion and expansion of CD45high microglial populations. Pharmacological TNT inhibition restores microglial homeostasis in ECM model. In conclusion, TNTs mediate neuroinflammation in the ECM model by transferring mitochondria and malarial pigment between microglia. Although mitochondrial transfer may transiently support cellular homeostasis, progressive malarial pigment accumulation triggers lipid metabolism dysregulation and amplified neuroinflammation. Inhibiting TNTs formation attenuates microglial hyperactivation, highlighting targeted regulation of TNT-mediated intercellular communication as a potential therapeutic approach for CM-associated neuropathology.\n\nID: 42385853\nTitle: Raffinose targets the NQO1/NF-\u03baB axis to attenuate DON-driven microglial activation and neuroinflammation via metabolic reprogramming.\nAbstract: Deoxynivalenol (DON), a prevalent mycotoxin in grain crops, can cross the blood-brain barrier (BBB) and cause neuroinflammation and neurobehavioral deficits in humans and animals. To date, the precise molecular mechanisms remain incompletely understood. Herein, we showed that DON triggers neurotoxicity by reprogramming microglial glycolysis via activation of the NQO1/NF-\u03baB pathway. Raffinose (Raf), a natural trisaccharide, effectively attenuated DON-induced neuroinflammation in vivo and in vitro. Mechanistically, Raf upregulated NQO1 transcription by selectively binding to Nrf2 at Val-514 and Cys-368, thereby reinforcing the NQO1-I\u03baB\u03b1 interaction, possibly through NQO1-associated regulatory interfaces. This interaction inhibited NF-\u03baB hyperactivation, suppressed glycolysis, and restored oxidative phosphorylation, thereby attenuating DON-induced pro-inflammatory microglial activation. Furthermore, NQO1 knockdown or Nrf2 knockout weakened the inhibitory effect of Raf on the NF-\u03baB signaling pathway and inflammatory activation state of microglia. In conclusion, our findings revealed that Raf supplementation could efficiently alleviate DON exposure-induced neuroinflammation and neurobehavioral deficits by modulating NQO1/NF-\u03baB-associated metabolic remodeling. These findings suggested that Raf may represent a potential therapeutic strategy against DON-induced neuroinflammation.\n\nID: 42385676\nTitle: Microglial fitness in moderation: Tuning TREM2 signaling through Ptpn6.\nAbstract: In this issue of Neuron, Etxeberria et al.1 report that Ptpn6 (SHP-1) restrains TREM2-driven microglial survival and DAM-like activation. Complete loss enhances amyloid containment and protects cortical neurites but triggers white matter degeneration, whereas partial reduction preserves benefit without harm-revealing that the threshold separating protective from detrimental microglial activation is regionally dissociable.\n\nID: 42384348\nTitle: Microglial Alkbh5 Deficiency Alleviates Chronic Restraint Stress-Induced Depression-like Behaviors in Mice.\nAbstract: Depression is a common and severe neuropsychiatric disorder, and its underlying biological regulatory mechanisms remain unclear. Microglia are resident immune cells of the central nervous system (CNS) that critically mediate the occurrence and development of CNS diseases, including depression. As the most abundant RNA modification, N6-methyladenosine (m6A) regulates microglial function. However, its role and molecular mechanisms in depression remain unclear. In this study, we found that m6A levels decreased in the microglia of the chronic restraint stress (CRS)-induced depression mouse model. Among m6A modulation factors, Alkbh5, a demethylase, showed a significant increase in expression level. Therefore, we generated microglial-specific conditional Alkbh5 knockout mice and found that Alkbh5 deficiency alleviated CRS-induced depression-like behaviors. Mechanistically, microglial Alkbh5 deficiency inhibited excessive microglial activation, rescued dendritic spine loss, and regulated the vascular changes during CRS. Together, these results highlight the important role of Alkbh5 in regulating microglial function in the CRS-induced depression mouse model, providing a potential therapeutic target for depression.\n\nID: 42383355\nTitle: Molecular mechanisms regulating cGAS/STING activation in health and disease.\nAbstract: The cGAS/STING pathway enables cells to sense cytosolic DNA and mount rapid innate immune responses to infection, cellular stress, and tissue damage. While essential for host defense and immune surveillance, inappropriate or sustained activation of this pathway can drive chronic inflammation, autoimmunity, and disease-associated immune dysfunction, which can promote cancer growth. Effective immunity therefore depends on precise regulatory control that restrains cGAS/STING activity under homeostatic conditions while preserving the capacity for swift and robust responses to diverse danger signals. In this Review, we synthesize emerging principles that regulate cGAS/STING signaling across cellular contexts to control signal initiation, amplification, and termination. We discuss how disruption, persistence, or pathological rewiring of these regulatory processes contributes to immune imbalance across health and disease, promoting chronic inflammation, immunosuppression, and tissue pathology, with particular relevance to tumor progression and therapeutic resistance. Finally, we consider how restoring appropriate cGAS/STING regulation, rather than simply enhancing or inhibiting pathway activity, may reestablish immune homeostasis and improve therapeutic outcomes in cancer and other inflammatory diseases, framing the pathway as a dynamic regulatory circuit rather than a simple linear signaling cascade.\n\nID: 42383100\nTitle: T Helper Cells and Cytokine Networks in the Immunopathogenesis of Multiple Sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder of CNS with demyelination, neurodegeneration and compartmentalized inflammatory disorder. Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta. The review also explores the cytokine network biomarkers, CSF and serum signatures and single-cell immune states, as well as existing and new drugs. These include migration blockade, targeting of S1P-receptors, anti-CD20 therapy, targeting of Th17/GM-CSF and JAK-STAT pathways, low-dose IL-2, approaches of targeting antigens and engineered Tregs. Investigating the areas of stage and compartment-specific CD4+ T-cell circuits can help to advance targeted immunomodulation in progressive MS and neuro-repair.\n\nID: 42382783\nTitle: HLA-DRB1*15:01 drives sex- and age-dependent microglial immune phenotypes and neuroimmune signaling.\nAbstract: The major histocompatibility complex class II (MHC-II) pathway is central to adaptive immunity and immune tolerance, and its age-related dysregulation is increasingly linked to chronic neuroinflammation. The HLA-DRB1*15:01 allele, the strongest genetic risk factor for multiple sclerosis, has been implicated in shaping pathogenic CD4+ T-cell responses and broader neuroimmune vulnerability, yet how this allele modulates age- and sex-dependent neuroimmune processes within the central nervous system (CNS) remains poorly defined. We investigated the impact of HLA-DRB1*15:01 expression using a humanized mouse model (HLA mice) and wild-type (WT) controls. Male and female mice were analyzed at 6, 9, and 15 months of age, with endocrine stratification in females. Behavioral testing, flow cytometry, immunofluorescence, and multiplex cytokine analyses were used to assess cognitive performance, glial immune-associated changes and oxidative stress, astrocyte-microglia IL-3/IL-3R signaling, endothelial activation, selective immune cell accumulation at CNS borders, tissue organization, and hippocampal cytokine profiles. HLA mice developed age- and sex-dependent cognitive impairment, most pronounced in aged females. HLA-DRB1*15:01 expression promoted progressive microglial immune-associated changes, characterized by increased CD14 and CD68 expression, elevated mitochondrial oxidative stress, altered astrocyte phenotypes, and enhanced IL-3/IL-3R signaling. Hippocampal axonal and myelin organization was disrupted in aged HLA mice and was spatially associated with increased microglial presence. HLA mice also exhibited selective immune remodeling, including increased accumulation of CD4+ T cells and NK1.1+CD3+ natural killer T (NKT) cells, particularly in females, accompanied by endothelial activation marked by elevated ICAM-1 and E-selectin expression. Hippocampal cytokine profiling revealed selective sex-biased alterations, without broad induction of classical inflammatory cytokines. Together, these findings demonstrate that HLA-DRB1*15:01 drives a coordinated, age- and sex-dependent neuroinflammatory program linking behavioral dysfunction, glial immune-associated changes and oxidative stress, selective immune cell recruitment, endothelial activation, tissue remodeling, and targeted cytokine imbalance. This integrated phenotype provides mechanistic insight into how this major MS risk allele confers vulnerability to chronic neuroinflammation during aging, with heightened impact in females, independent of reproductive cycling stage.\n\nID: 42377966\nTitle: Blood cytotoxic natural killer-like CD8 + CD94+ T cells migrate to the brain and predict multiple sclerosis severity.\nAbstract: Memory CD8+ T cells are central to multiple sclerosis (MS) and undergo clonal expansion, but disease-associated states remain incompletely defined. By single-cell profiling of circulating memory CD8+ T cells from patients with relapsing-remitting MS, healthy volunteers, and neuroinflammatory controls, we identified an MS-associated cytotoxic subset with NK-like features. These cells increase around relapse activity and belong to an oligoclonal reservoir. In an independent cohort sampled at the first clinical event, an elevated frequency of NK-like CD8+ T cells predicted an aggressive MS course two years later and was associated with a migratory/inflammatory program. Bulk and single-cell RNA-seq confirmed the NK-like transcriptional signature, and functional assays demonstrated TCR-independent cytotoxicity. Immunostaining and spatial transcriptomics revealed enrichment of these cells in MS lesions and a spatial association with macrophages/microglia. Together, our results identify a cytotoxic NK-like CD8+ T-cell subset that links peripheral inflammation to CNS lesions and may serve as an early biomarker of MS severity.\n\nID: 42377668\nTitle: Near\u2011Infrared Photobiomodulation in White\u2011Matter Disease: From Microglial States to Measurable Endpoints.\nAbstract: White-matter (WM) injury contributes to disability across multiple sclerosis, traumatic brain injury, Alzheimer's disease and related dementias, and small-vessel disease. We use microglial state programs as an organizing axis for WM injury-to-repair logic, while emphasizing that WM outcomes are multicellular and involve oligodendrocyte-lineage cells, astrocytes, axons/neurons, and vascular factors. Microglia span an injury-repair continuum, from inflammatory programs that increase oxidative stress and debris burden to repair-competent programs that support debris handling, remyelination, and axonal integrity. Near-infrared photobiomodulation (PBM; ~800-1100\u00a0nm) is most consistently associated with modulation of mitochondrial redox/bioenergetic pathways and inflammatory tone. CCO-centered mechanistic framing is best established near ~\u2009800-850\u00a0nm, whereas longer wavelengths (e.g., ~\u20091064-1070\u00a0nm) may involve additional initiating mechanisms with downstream convergence on shared redox/bioenergetic and inflammatory pathways. Across demyelination and spinal cord injury models, appropriately dosed PBM has been reported to reduce inflammatory glial readouts and to associate with improved myelin/axon-related endpoints and functional measures, although mechanistic certainty varies across models. Human evidence remains early but broadly supports safety; a randomized trial in moderate traumatic brain injury reported treatment-related changes in diffusion-MRI WM metrics, while small dementia and chronic-injury studies report heterogeneous cognitive and physiological signals. Given dose dependence and depth-limited transcranial delivery, we synthesize mechanism-informed, dose-aware reporting guidance and WM-anchored outcome frameworks that pair diffusion MRI/DTI with interpretable biomarkers (e.g., NfL, GFAP, sTREM2) and thermally controlled sham designs. We also note potential indirect/systemic contributions that could help reconcile depth-dose constraints with deeper WM effects.\n\nID: 42376811\nTitle: Longitudinal magnetic resonance spectroscopy study of metabolite changes over 2\u2009years in relapsing and primary progressive multiple sclerosis treated with ocrelizumab.\nAbstract: Magnetic resonance spectroscopy (MRS) offers non-invasive assessments of neuron-oligodendrocyte coupling and neuroinflammation to monitor treatment response in multiple sclerosis (MS). To track changes in N-acetylaspartate and myo-inositol in relapsing MS (RMS) and primary progressive MS (PPMS) patients treated with ocrelizumab over 2\u2009years. Single-voxel MRS at 3T was acquired at baseline in 10 healthy controls (HCs), and weeks 0, 12, 24, 52, and 96 in MS participants at a single center. Baseline myo-inositol was higher in PPMS than RMS (p\u2009=\u20090.047) and HC (p\u2009=\u20090.001), and correlated with disability across both MS groups (r\u2009=\u20090.57, p\u2009=\u20090.0006). Following treatment with ocrelizumab, both RMS and PPMS demonstrated declines in myo-inositol over time, returning toward HC levels (RMS p\u2009=\u20090.016; PPMS p\u2009=\u20090.004). Conversely, N-acetylaspartate was not different between groups and remained stable over time. Ocrelizumab treatment is associated with declining myo-inositol levels measured by MRS in both RMS and PPMS. Myo-inositol offers a unique biomarker to track resolution of gliosis and reactive microglia with treatment. Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

Aging modifies MS pathobiology, with the dominant disease mechanisms moving from focal, relapse-driven inflammation to chronic, compartmentalized neuroinflammation and neurodegeneration. In this narrative review, we summarize current knowledge on the relationship between brain aging and MS, integrating clinical, radiological, pathological and therapeutic evidence. We first discuss mechanisms of immunosenescence and \"inflammaging\", including changes in adaptive and innate immunity, gut microbiota dysbiosis, mitochondrial dysfunction and blood-brain barrier dysfunction, and how these processes favor microglial activation, slowly expanding lesions, smouldering MS and progression independent of relapse activity. We then examine the impact of age on disability trajectories, cognitive decline and comorbidities, and the role of vascular and neurodegenerative mechanisms. The review also addresses age-related changes in safety and efficacy of disease-modifying therapies (DMT), with a focus on high-efficacy DMT, de-escalation and discontinuation strategies, and the management of infections, malignancies and polypharmacy in older pwMS. Finally, we describe new approaches relevant to this population, including Bruton's tyrosine kinase inhibitors, neuroprotective and remyelinating agents, advanced cellular therapies and lifestyle-based interventions. We conclude by outlining practical implications for personalized treatment decisions in older pwMS and open questions that future clinical trials and biomarker studies must address.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The main causes of poor prognosis are neuroinflammation, blood-brain barrier (BBB) disruption and brain edema following hemorrhage. Didymin has shown neuroprotective effects in intracerebral hemorrhage; however, its regulatory role in SAH remains unclear. The rat SAH model was established using the internal carotid artery puncture method, while an in vitro model was developed by stimulating human brain microvascular endothelial cells (HBMECs) with hemoglobin (Hb). Following didymin treatment, neurological functional outcomes were assessed using the modified Garcia score and the balance beam test. Nissl staining was performed to evaluate neuronal pathological changes. Immunofluorescence staining was employed to assess microglial activation and BBB integrity. Brain water content was measured to evaluate the severity of cerebral edema. Western blot analysis was utilized to detect the expression of matrix metalloproteinase 9 (MMP9), apoptosis-related proteins (Bcl-XL, Bcl-2, Bax), pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and tight junction proteins (ZO-1, Occludin). Didymin treatment significantly improved neurological function scores in SAH rats by alleviating neuronal damage and apoptosis. On one hand, didymin reduced post-SAH neuroinflammation by inhibiting excessive microglial activation and the expression of pro-inflammatory cytokines. On the other hand, didymin preserved BBB integrity and alleviated brain edema by downregulating MMP9 expression. In Hb-induced cell model, didymin suppressed MMP9 expression and promoted the expression of tight junction proteins. In this study, we demonstrated that didymin mitigates neuronal damage and apoptosis following SAH, effectively suppresses neuroinflammation, maintains the integrity of the BBB, and attenuates brain edema. These findings suggest that didymin holds promise as a potential therapeutic candidate for the treatment of SAH.\n --- END ACTUAL ABSTRACT FOR 42404111 ---\n\n- ERROR: You cited ID: 42399626 for the quote: \"Neuroinflammation, particularly glial activation across microglial, astrocytic, and oligodendrocyte lineages, and its downstream consequences... represents a central pathophysiological mechanism\"\n FACT: Ellipses (...) are strictly forbidden.

A rapidly accumulating body of evidence has not simply challenged the long-dominant monoamine deficiency hypothesis but has provided a mechanistic framework that may explain many of the observed monoaminergic alterations in depressive cohorts, including IDO1-driven serotonin depletion, cytokine-mediated AMPA receptor internalization, and HPA-immune feedback dysregulation. Neuroinflammation, particularly glial activation across microglial, astrocytic, and oligodendrocyte lineages, and its downstream consequences for tryptophan metabolism, glutamatergic transmission, synaptic plasticity, and neurotrophic signaling, represents a central pathophysiological mechanism in a substantial subgroup of depressed patients. Peripheral inflammatory markers, including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha, are elevated in a significant proportion of individuals with major depressive disorder, and these elevations predict poor response to conventional antidepressants while identifying patients who may respond preferentially to anti-inflammatory strategies. Post-mortem studies, positron emission tomography imaging of translocator protein density, and transcriptomic analyses of brain tissue have collectively provided consistent, though not yet fully definitive, evidence that microglial activation is a neurobiological feature of depression rather than a consequence of comorbid physical illness. This review synthesizes current mechanistic understanding of the neuroinflammatory hypothesis of depression, examines the evidence base from epidemiological, biomarker, neuroimaging, and interventional studies, including null findings and methodological limitations, evaluates emerging therapeutic strategies targeting the immune-brain interface, and identifies the critical questions that will determine whether immunopsychiatry fulfills its promise as a precision medicine framework for treatment-resistant depression.\n --- END ACTUAL ABSTRACT FOR 42399626 ---\n\n- ERROR: You cited ID: 42391876 for the quote: \"Hypoxia first triggered mitochondrial metabolic reprogramming in microglia... which subsequently drove the conversion to the M1 pro-inflammatory phenotype.\"\n FACT: Ellipses (...) are strictly forbidden.

Microglial M1 polarization and changes in mitochondrial metabolism are crucial in hypoxic brain injury. The cold-inducible RNA-binding protein (CIRBP) is known to regulate mitochondrial balance and inflammatory responses. However, its role in hypoxia-induced microglial metabolic changes, polarization issues, and anxiety-like behaviors is still unclear. This study established an in vivo mouse model of high-altitude hypoxia, an in vitro hypoxic injury model of BV2 microglia, and an in vitro neuronal intervention model with microglia-derived conditioned medium. Integrating in vivo and in vitro experimental designs, we further systematically elucidated the potential molecular mechanisms underlying hypoxic brain injury. Findings indicated that high-altitude hypoxic exposure led to anxiety-like behaviors, social dysfunction, and neuronal and synaptic damage in the hippocampal CA1 region of mice. Hypoxia first triggered mitochondrial metabolic reprogramming in microglia, characterized by inhibition of oxidative phosphorylation, decreased ATP production, and accumulation of reactive oxygen species (ROS) and lactate, which subsequently drove the conversion to the M1 pro-inflammatory phenotype. Inhibition of microglial activation by minocycline significantly reversed hypoxia-induced synaptic damage. At the molecular level, hypoxia downregulated CIRBP expression in microglia. Overexpression of CIRBP in microglia ameliorated mitochondrial metabolic dysfunction and regulated microglial polarization, while knockdown of CIRBP in microglia exacerbated these abnormalities. Targeted overexpression of CIRBP in microglia within the hippocampal CA1 region significantly attenuated hypoxia-induced neuronal damage and behavioral abnormalities. This study elucidates a novel mechanism by which CIRBP in microglia mediates hypoxic brain injury, offering a potential therapeutic target for neuropsychiatric disorders associated with high-altitude hypoxia.\n --- END ACTUAL ABSTRACT FOR 42391876 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained.

"rawResponse": "### [CLAIM EVALUATED AND ANSWER TO USER]\nDoes chronic latent Epstein-Barr Virus (EBV) reactivation drive microglial activation and subsequent myelin destruction in Multiple Sclerosis via the activation of the cGAS-STING innate immune pathway?\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the potential causality of EBV in Multiple Sclerosis (MS) has highlighted an association, but the specific mechanistic requirement of the cGAS-STING pathway as a conduit for microglial-mediated myelin destruction in this context remains an area of active study rather than established fact. While mitochondrial DNA leakage and cGAS-STING activation are verified drivers of neuroinflammation and white matter pathology in various neurological conditions, the evidence linking these to EBV specifically is limited to the potential role of extracellular vesicles (sEVs) in disseminating viral components such as EBER1.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenesis of Multiple Sclerosis is increasingly recognized as a multi-axial process involving both peripheral immune triggers and chronic, compartmentalized neuroinflammation. Epigenetic and metabolic studies indicate that \"Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression.\" Specifically, the cGAS-STING axis has emerged as a major mediator of such progression, as \"mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction.\" \n\nWhile EBV is a strong candidate as an MS trigger, its precise mechanism of CNS influence remains under scrutiny. Current literature identifies sEVs as a vector for viral components, noting that \"EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency\". However, the direct, causal coupling of EBV-encoded products to cGAS-STING activation in microglia, and the subsequent extent of myelin loss, requires further investigation. We observe that \"Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner,\" suggesting that viral-induced metabolic reprogramming could potentially act as a trigger.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **sEV-Mediated Viral Dissemination:** Small extracellular vesicles act as carriers for immunostimulatory EBV non-coding RNAs (EBER1) to distal tissues.\n* **cGAS-STING Rheostat:** The cGAS-STING pathway functions as a tunable control node, not merely a binary switch, making it highly sensitive to metabolic shifts.\n* **Mitochondrial DNA (mtDNA) Leakage:** Cytosolic leakage of mtDNA is a conserved activator of STING-mediated neuroinflammation across AD, PD, and ischemia models.\n* **Metabolic Checkpoints:** Lactylation of core pathway components serves as a metabolic-immune bridge regulating STING stability and activity.\n* **Regional Glial Heterogeneity:** Spinal cord and brain microglia exhibit distinct activation profiles during demyelination, complicating global neuroinflammatory models.\n* **T-Cell-Microglia Crosstalk:** Cytotoxic NK-like CD8+ T cells spatially associate with microglia in MS lesions, linking peripheral immune states to local tissue destruction.\n* **Mitochondrial Protection:** Preserving mitochondrial integrity effectively suppresses mtDNA-driven innate immune activation, as demonstrated by the efficacy of EE and other interventions.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The etiology of Multiple Sclerosis (MS) is unknown but several data support the hypothesis of possible infectious agents which may act as a trigger for the pathogenic cascade. Human endogenous retrovirus (HERV-W/MSRV), Epstein Barr Virus (EBV) and Mycobacterium avium ss. paratuberculosis (MAP) have been associated to Multiple Sclerosis. In this study, we evaluated the humoral response against different peptides: the human endogenous retrovirus HERV-Wenv73-88, MAP106c121-132 from MAP, EBNA1 400-413 from EBV and the homologous human peptide MBP85-98 in a cohort of MS patients treated with natalizumab. Results showed a statistically significant difference in the response against the HERV-W peptide in MS patients after two years of natalizumab treatment.",
"33291536": "ID: 33291536\nTitle: The STING-IFN-\u03b2-Dependent Axis Is Markedly Low in Patients with Relapsing-Remitting Multiple Sclerosis.\nAbstract: Cyclic GMP-AMP-synthase is a sensor of endogenous nucleic acids, which subsequently elicits a stimulator of interferon genes (STING)-dependent type I interferon (IFN) response defending us against viruses and other intracellular pathogens. This pathway can drive pathological inflammation, as documented for type I interferonopathies. In contrast, specific STING activation and subsequent IFN-\u03b2 release have shown beneficial effects on experimental autoimmune encephalomyelitis (EAE) as a model for multiple sclerosis (MS). Although less severe cases of relapse-remitting MS (RRMS) are treated with IFN-\u03b2, there is little information correlating aberrant type I IFN signaling and the pathologic conditions of MS. We hypothesized that there is a link between STING activation and the endogenous production of IFN-\u03b2 during neuroinflammation. Gene expression analysis in EAE mice showed that Sting level decreased in the peripheral lymphoid tissue, while its level increased within the central nervous system over the course of the disease. Similar patterns could be verified in peripheral immune cells during the acute phases of RRMS in comparison to remitting phases and appropriately matched healthy controls. Our study is the first to provide evidence that the STING/IFN-\u03b2-axis is downregulated in RRMS patients, meriting further intensified research to understand its role in the pathophysiology of MS and potential translational applications.",
"33948692": "ID: 33948692\nTitle: Multiple sclerosis is linked to MAPKERK overactivity in microglia.\nAbstract: Reassessment of published observations in patients with multiple sclerosis (MS) suggests a microglial malfunction due to inappropriate (over)activity of the mitogen-activated protein kinase pathway ERK (MAPKERK). These observations regard biochemistry as well as epigenetics, and all indicate involvement of this pathway. Recent preclinical research on neurodegeneration already pointed towards a role of MAPK pathways, in particular MAPKERK. This is important as microglia with overactive MAPK have been identified to disturb local oligodendrocytes which can lead to locoregional demyelination, hallmark of MS. This constitutes a new concept on pathophysiology of MS, besides the prevailing view, i.e., autoimmunity. Acknowledged risk factors for MS, such as EBV infection, hypovitaminosis D, and smoking, all downregulate MAPKERK negative feedback phosphatases that normally regulate MAPKERK activity. Consequently, these factors may contribute to inappropriate MAPKERK overactivity, and thereby to neurodegeneration. Also, MAPKERK overactivity in microglia, as a factor in the pathophysiology of MS, could explain ongoing neurodegeneration in MS patients despite optimized immunosuppressive or immunomodulatory treatment. Currently, for these patients with progressive disease, no effective treatment exists. In such refractory MS, targeting the cause of overactive MAPKERK in microglia merits further investigation as this phenomenon may imply a novel treatment approach.",
"38878778": "ID: 38878778\nTitle: STING orchestrates the neuronal inflammatory stress response in multiple sclerosis.\nAbstract: Inflammation-induced neurodegeneration is a defining feature of multiple sclerosis (MS), yet the underlying mechanisms remain unclear. By dissecting the neuronal inflammatory stress response, we discovered that neurons in MS and its mouse model induce the stimulator of interferon genes (STING). However, activation of neuronal STING requires its detachment from the stromal interaction molecule 1 (STIM1), a process triggered by glutamate excitotoxicity. This detachment initiates non-canonical STING signaling, which leads to autophagic degradation of glutathione peroxidase 4 (GPX4), essential for neuronal redox homeostasis and thereby inducing ferroptosis. Both genetic and pharmacological interventions that target STING in neurons protect against inflammation-induced neurodegeneration. Our findings position STING as a central regulator of the detrimental neuronal inflammatory stress response, integrating inflammation with glutamate signaling to cause neuronal cell death, and present it as a tractable target for treating neurodegeneration in MS.",
"39656548": "ID: 39656548\nTitle: Cathelicidin antimicrobial peptide expression in neutrophils and neurons antagonistically modulates neuroinflammation.\nAbstract: Multiple sclerosis (MS) is an autoimmune disease that affects the CNS, the pathophysiology of which remains unclear and for which there is no definitive cure. Antimicrobial peptides (AMPs) are immunomodulatory molecules expressed in various tissues, including the CNS. Here, we investigated whether the cathelicidin-related AMP (CRAMP) modulated the development of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. We showed that, at an early stage, CNS-recruited neutrophils produced neutrophil extracellular traps (NETs) rich in CRAMP that were required for EAE initiation. NET-associated CRAMP stimulated IL-6 production by dendritic cells via the cGAS/STING pathway, thereby promoting encephalitogenic Th17 response. However, at a later disease stage, neurons also expressed CRAMP that reduced EAE severity. Camp knockdown in neurons led to disease exacerbation, while local injection of CRAMP1-39 at the peak of EAE promoted disease remission. In vitro, CRAMP1-39 regulated the activation of microglia and astrocytes through the formyl peptide receptor (FPR) 2. Finally, administration of butyrate, a gut microbiota-derived metabolite, stimulated the expression of neural CRAMP via the free fatty acids receptors 2/3 (FFAR2/3), and prevented EAE. This study shows that CRAMP produced by different cell types has opposing effects on neuroinflammation, offering therapeutic opportunities for MS and other neuroinflammatory disorders.",
"39766068": "ID: 39766068\nTitle: Epstein Barr Virus (EBV) Latent Membrane Protein 1 (LMP-1) Regulates Functional Markers in Intermediate and Non-Classical Monocytes.\nAbstract: Background: The Epstein-Barr virus (EBV) infects more than 90 percent of the human population. In pediatric patients, the innate immune response against EBV primary infection plays a key role. Monocytes and macrophages can have distinct functions depending on the microenvironment surrounding them. At least three monocyte subpopulations can be differentiated depending on membrane protein expression: classical (C, CD14++CD16-), intermediate (I, CD14++CD16+), and non-classical (NC, CD14+CD16++). They also modulate T and B lymphocyte activation/inhibition through the expression of costimulatory molecules such as CD80, CD86, and PD-L1. Yet, little is known about monocytes' role in EBV infection. Methods: Peripheral blood and tonsil biopsies of EBV primary infected (PI) patients, healthy carriers (HCs), and patients undergoing reactivation (R) were studied. Results: Classical monocytes prevailed in all infectious statuses. Tonsillar CD163 positively correlated with CD163 expression in NC monocytes in HCs. PD-L1+ cells in the tonsil positively correlated with PD-L1 expression in NC monocytes. LMP-1 viral latent protein presented a positive correlation with PD-L1, CD163, and CD206 expression in the NC subpopulation. Conclusions: Our results evidence the predominant role of I and NC monocytes' response against EBV infection. Furthermore, the viral oncoprotein LMP-1 could be involved in the expression of regulatory proteins in I and NC monocytes.",
"40079734": "ID: 40079734\nTitle: EBV enhances immunotherapy sensitivity in intrahepatic cholangiocarcinoma through cGAS-STING pathway activation.\nAbstract: The absence of representative Epstein-Barr virus-associated intrahepatic cholangiocarcinoma (EBVaICC) cell lines has limited our understanding of the molecular and immunological characteristics of this cancer subtype. We reviewed patients with metastatic cholangiocarcinoma at Sun Yat-sen University Cancer Center from January 2015 to August 2023. Among them, 22 patients with EBVaICC and 66 patients with non-EBVaICC who received anti-PD1 treatment were included. Additionally, 2 EBV-positive ICC cell lines, RBE-EBV and HuH28-EBV, were developed through cell-to-cell infection. Stable EBV infection and responsiveness to viral reactivation were confirmed. Transcriptomic and bioinformatics analyses were performed, and in vitro experiments examined the immune effects of EBV-positive ICC. Key immune-related genes and cytokines were validated by reverse transcription quantitative polymerase chain reaction and ELISA in cell lines and patient plasma samples. In this study, we found that patients with EBVaICC showed enhanced immune responses and improved overall and progression-free survival compared to patients with non-EBVaICC. We first successfully established and validated 2 EBV-positive ICC cell lines (RBE-EBV and HuH28-EBV). These cell lines were confirmed for stable EBV infection and displayed responsiveness to viral reactivation, making them suitable for future studies. Transcriptomic analyses and in vitro studies revealed that EBV activated the cGAS-STING pathway, resulting in MHC-I upregulation and CXCL10 secretion in ICC cells, which collectively enhanced CD8+ T cell chemotaxis and cytotoxicity. Furthermore, ELISA analysis showed higher plasma levels of CXCL10 and IFN-\u03b3 in patients with EBVaICC, suggesting a potential role for EBV in enhancing immunotherapy sensitivity in this subtype. The established EBV-positive ICC cell lines revealed enhanced immunogenicity driven by cGAS-STING pathway activation, providing valuable models for future research and insights into the mechanisms of improved immunotherapy sensitivity in EBVaICC.",
"40275354": "ID: 40275354\nTitle: Targeting microglia-Th17 feed-forward loop to suppress autoimmune neuroinflammation.\nAbstract: Microglia and Th17 cells are the major immunopathogenic cells in multiple sclerosis and its animal model of immune aspects, experimental autoimmune encephalomyelitis (EAE). While studies have highlighted the distinct roles of microglia and Th17 cells in EAE, it remains unclear whether microglia, as potential professional antigen-presenting cells, activate and stabilize the effector program of EAE-pathogenic Th17 cells in vivo; and if so, whether the Th17 could in turn reinforce the active state of the microglia. Our data demonstrate in an array of mouse models, including active/passive-EAE and transgenic mice, a microglia-Th17 feed-forward activation loop drives EAE disease progression through a mechanism dependent on both MHC-II, proinflammatory cytokines, inflammatory chemokines as well as STING\u2192NF-\u03baB pathway in the microglia and effector cytokines produced by the pathogenic Th17 cells. We also captured and identified the molecular properties of the feed-forward loop, which are two-cell entities of microglia-Th17, and proved them as the functional units of antigen presentation and bi-directional activation between the two cell types. Moreover, ACT001, an orphan drug to treat glioblastoma, disrupts this feed-forward activation loop by inhibiting the STING\u2192NF-\u03baB pathway in microglia, thereby alleviating EAE. These findings emphasize the importance of interactions and bi-directional activations between microglia and Th17 in the autoimmune neuroinflammation, and provide rationale for further investigation on ACT001 as therapeutic option for autoimmune inflammatory diseases driven by similar mechanisms.",
"40399572": "ID: 40399572\nTitle: Innate Immune Recognition of EBV.\nAbstract: Epstein-Barr virus (EBV) is a very successful human pathogen, with ~95% seroprevalence worldwide (Mentzer et al, Nat Commun 13:1818, 2022). If contracted in early childhood, EBV infection is typically asymptomatic; however, infections in adolescence and adulthood can manifest as infectious mononucleosis (IM). The innate immune response is the first line of defense, and its function is critical for controlling EBV infection. During EBV infection, components of the virus, known as pathogen-associated molecular patterns (PAMPs), are recognized by germline-encoded pattern recognition receptors (PRRs). PRRs are found on both non-immune and immune cells including antigen-presenting cells, such as macrophages, monocytes, dendritic cells, natural killer (NK), and mast cells. PRRs are also found on B cells and epithelial cells, the primary targets of EBV infection. Without immune surveillance, EBV can transform cells inducing various malignancies. Conversely, a prolonged innate immune response can lead to chronic inflammation which increases the likelihood of cancer. This review discusses innate immune recognition of EBV and its associated diseases.",
"40526717": "ID: 40526717\nTitle: Sp140L functions as a herpesvirus restriction factor suppressing viral transcription and activating interferon-stimulated genes.\nAbstract: Herpesviruses, including Epstein-Barr virus (EBV) - a human oncogenic virus and essential trigger of multiple sclerosis - must bypass host DNA-sensing mechanisms to establish lifelong, latent infection. Therefore, herpesviruses encode viral proteins to disrupt key host factors involved in DNA sensing and viral restriction. The first viral latency protein expressed, EBNA-LP, is essential for transformation of na\u00efve B cells and establishment of viral gene expression, yet its role in evading host defenses remains unclear. Using single-cell RNA sequencing of EBNA-LP Knockout (LPKO)-infected B cells, we reveal an antiviral response landscape implicating the \"speckled proteins\" as key cellular restriction factors countered by EBNA-LP. Specifically, loss of Sp100 or the primate-specific Sp140L reverses the restriction of LPKO, suppresses a subset of canonically interferon-stimulated genes, and restores transcription of essential latent viral genes and cellular proliferation. Notably, we also identify Sp140L as a restriction target of the herpesvirus saimiri ORF3 protein, implying a role for Sp140L in immunity to other diverse DNA viruses. This study reveals Sp140L as a restriction factor that we propose links sensing and transcriptional suppression of viral DNA to an Interferon-independent innate immune response, likely relevant to all nuclear DNA viruses.",
"40613364": "ID: 40613364\nTitle: Stimulator of Interferon Genes (STING)-Type I Interferon Signaling: Bridging Immunity and Pain.\nAbstract: Interferons (IFNs) are cytokines with diverse functions, possessing antiviral, antiproliferative, and immunomodulatory effects. IFN-\u03b1 and IFN-\u03b2, key members of the type I interferon (IFN-I) family, are widely used in the treatment of diseases such as hepatitis and multiple sclerosis. In the nervous system, microglia, astrocytes, and neurons express IFN-I receptors. Beyond their classical transcriptional roles, IFN-Is can suppress neuronal activity and synaptic transmission through nongenomic mechanisms, producing potent analgesic effects. However, IFN-Is are active in signaling pathways such as phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK), and the MAPK-interacting serine/threonine-protein kinase (MNK)-eukaryotic initiation factor 4E (eIF4E) pathway, which can sensitize peripheral nociceptors and contribute to nociceptive responses. This narrative review explores recent advances in understanding the roles of IFN-I and the cyclic-GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling cascade in acute and chronic nociceptive responses, which are increasingly recognized but remain a subject of debate. Recent studies suggest that the STING-IFN-I pathway has complex, stage-dependent effects on nociception. In the middle to late stages of the nociceptive response, this pathway can activate signal transducer and activator of transcription (STAT) signaling, as well as microglial mediated STING pathways and tumor necrosis factor (TNF) receptor-associated factor (TRAF) family member-associated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB activator) collectively referred to as TANK. These pathways increase pro- and anti-inflammatory cytokine production, promote microglial M1 polarization, and inhibit endoplasmic reticulum-phagy (ER-phagy) in the central nervous system (CNS). These mechanisms contribute to central sensitization while modulating the analgesic effects of IFN-Is. Thus, the STING-IFN-I pathway plays a dual role in nociception, with both pro-nociceptive and analgesic effects that are dependent on the stage of the nociceptive response. Understanding the differential roles of STING-IFN-I signaling in nociceptors under physiological and pathological conditions could pave the way for the development of targeted nociceptive response management therapies.",
"40686188": "ID: 40686188\nTitle: Type I Interferon Signaling Augments Autoimmunity in Neuromyelitis Optica Spectrum Disorder.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by anti-aquaporin 4 (AQP4) antibody-mediated astrocyte damage and subsequent demyelination. Prior attempts to treat NMOSD with interferon-beta (IFN-\u03b2), a disease-modifying therapy for multiple sclerosis, resulted in worsening of disease activity, with an unknown mechanism. Here, robust activation of the cGAS-STING-IFN-I signaling pathway is identified\u00a0in myeloid cells in both the periphery and central nervous system. The abnormal IFN-I response gives rise to an increase in the number of AQP4 antigen-specific autoreactive T cells. Sting deficiency can significantly blunt the activation of AQP4-specific T cells, as well as the IFN-I activity in microglia, and attenuate astrocyte damage. Consequently, the clinical manifestation of NMOSD is ameliorated in a passive transfer mouse model of NMOSD. Further, treatment with STING inhibitor H151 alleviates the severity of NMOSD mouse models. These findings uncover the cGAS-STING-IFN-I pathway in promoting autoreactive T cells and establish a foundation for inhibiting this pathway as a new therapeutic revenue for NMOSD.",
"40808412": "ID: 40808412\nTitle: cGAS-STING axis: A central regulator of neural homeostasis and neuroinflammatory pathogenesis.\nAbstract: An increasing amount of evidence shows that type I interferon response, which is induced by cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) and stimulator of interferon genes (STING) is closely associated with health and neuroinflammatory diseases. Abnormal activation or loss of control of the cGAS-STING axis affects the development of neuroinflammation. Thus, we examined its role in major neurological diseases, including traumatic brain injury, Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, herpes simplex encephalitis, and ataxia-telangiectasia. Additionally, targeted intervention of the cGAS-STING axis to control neuroinflammation and treat related diseases has become the focus of current clinical research. This article describes the development of cGAS inhibitors and small molecules that target the cGAS-STING axis and explores the potential applications of STING inhibitors and agonists in clinical research. In summary, the cGAS-STING axis may impact neurological diseases more than a single protein or gene. Future studies should focus on elucidating the functional dynamics and regulatory networks of this axis and delineating its crosstalk with other signaling cascades. These investigations will provide mechanistic insights for developing targeted therapeutic strategies for associated disorders and potentially facilitate drug repurposing across diverse disease contexts.",
"40817248": "ID: 40817248\nTitle: TRIM6 ablation reverses ICB resistance in MSS gastric cancer by unleashing cGAS-STING-dependent antitumor immunity.\nAbstract: Gastric cancers are classified into four molecular subtypes according to The Cancer Genome Atlas (TCGA) classification: Epstein-Barr virus-positive (EBV-positive), microsatellite instability-high (MSI-H), chromosomal instability (CIN), and genomically stable (GS). Unlike MSI-H gastric cancer, GS and CIN subtypes exhibit immunologically inert microenvironments and demonstrate minimal response to immune checkpoint blockade (ICB), necessitating novel strategies to overcome immunotherapy resistance. Through weighted gene co-expression network analysis (WGCNA), we identified the E3 ubiquitin ligase TRIM6 as inversely associated with MSI-H status. TRIM6-knockout murine models and subcutaneous tumors were subjected to flow cytometry, RNA sequencing, immunoblotting, and ubiquitination assays to characterize tumor-infiltrating lymphocytes (TILs), pathway activation, and TRIM6-mediated regulation of the cGAS-STING axis. Hypermethylation-mediated TRIM6 downregulation distinguished MSI-H from microsatellite stable (MSS) gastric cancers. Clinically, TRIM6 expression inversely correlated with cytotoxic T lymphocyte (CTL) infiltration and anti-PD-1/PD-L1 therapeutic efficacy. Mechanistically, TRIM6 catalyzed K27-linked polyubiquitination of cGAS, triggering its proteasomal degradation and consequent suppression of the cGAS-STING pathway. TRIM6 ablation enhanced CD8+ T lymphocytes infiltration via cGAS-mediated innate immune response and synergized with anti-PD-L1 therapy in MSS gastric tumors. Our results elucidate TRIM6-mediated suppression of antitumor immunity as a novel mechanism underlying ICB resistance in MSS gastric cancer, positioning TRIM6 as both a predictive biomarker and therapeutic target for immunologically cold subtypes.",
"40906893": "ID: 40906893\nTitle: LRRK2 kinase activity restricts NRF2-dependent mitochondrial protection in microglia.\nAbstract: Mounting evidence supports a critical role for central nervous system (CNS) glial cells in neuroinflammation and neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's Disease (PD), Multiple Sclerosis (MS), as well as neurovascular ischemic stroke. Previously, we found that loss of the PD-associated gene leucine-rich repeat kinase 2 (Lrrk2) in macrophages, peripheral innate immune cells, induced mitochondrial stress and elevated basal expression of type I interferon (IFN) stimulated genes (ISGs) due to chronic mitochondrial DNA engagement with the cGAS/STING DNA sensing pathway. Here we report that loss of LRRK2 results in a paradoxical response in microglial cells, a CNS-specific macrophage population. In primary murine microglia and microglial cell lines, loss of Lrrk2 reduces tonic IFN signaling leading to a reduction in ISG expression. Consistent with reduced type I IFN, mitochondria from Lrrk2 KO microglia are protected from stress and have elevated metabolism. These protective phenotypes involve upregulation of NRF2, an important transcription factor in the response to oxidative stress and are restricted by LRRK2 kinase activity. Collectively, these findings illustrate a dichotomous role for LRRK2 within different immune cell populations and give insight into the fundamental differences between immune regulation in the CNS and the periphery.",

However, the mechanisms of protein conformational changes underlying the interactions between nanoparticles and protein coronas remain poorly understood. In this study, we prepared small molecule self-assembled nanoparticles (Aloin NPs) as a research tool to investigate the allosteric mechanism of protein coronas. Aloin NPs showed a propensity to capture multiple proteins in cells. In particular, Aloin NPs specifically bound to myotrophin (MPTN) as a major protein corona through a multivalent hydrogen bond-mediated nanoprotein interface. Molecular modeling and hydrogen-deuterium exchange mass spectrometry (MS) demonstrated that Aloin NPs promoted a conformational rearrangement of MPTN via a 'finger-unclasping' pattern. We then adapted the APEX2 proximity labeling strategy to investigate the conformation-dependent changes in the MPTN interactome and identified peroxiredoxin 6 (PRDX6) as a key substrate protein of MPTN in microglia. Additionally, we observed that MPTN conformational change-dependent PRDX6 release protected the mitochondrial membrane by reducing reactive oxygen species. Consequently, Aloin NPs effectively inhibited the release of mitochondrial DNA to block the downstream cGAS-STING signaling pathway, thereby reprogramming microglial polarization. In translational medicine, Aloin NPs play a role in protecting neurons from microglia-induced inflammatory injury with no significant adverse effects, ultimately improving Parkinson's disease-associated symptoms. Taken together, our study provides insights into the molecular mechanisms by which nanoparticles regulate the conformational change of protein coronas for human disease therapy.",

The presence of EBV-infected cells in the central nervous system (CNS) of MS patients, but not in neurologically healthy individuals, suggests that viral persistence in the CNS may drive MS. However, why there is such a long interval between initial infection and the development of disease is unknown. To model the effects of EBV infection on the brain, we intracerebrally infected mice with murine gammaherpesvirus-68 (MHV68), a virus genetically related to EBV that causes transient pathology strikingly similar to that seen in humans after acute EBV infection. One month following MHV68 infection, we administered myelin oligodendrocyte glycoprotein (MOG) peptide to evaluate the effects of prior MHV68 infection on the response to an additional inflammatory stimulus of the CNS. Virus persistence, microglial activation and immune cell infiltration were evaluated over time using flow cytometry. Intracerebral MHV68 infection induced mild brain demyelination and ataxia, a common symptom of MS, that both quickly resolved. However, administration of MOG peptide one month later led to more severe brain demyelination and more sustained ataxia, suggesting that prior MHV68 infection sensitized the mice to a newly introduced immune stimulus. Further investigation revealed that following CNS infection, MHV68 persisted in microglia, where it induced a primed phenotype marked by elevated MHC-II expression and heightened immune reactivity for at least six months. Primed microglia displayed increases in the labile iron pool, and iron chelation reduced microglial priming. Early antiviral treatment during MHV68 infection completely prevented subsequent MOG-induced demyelinating disease. These findings support a two-step mechanism by which CNS infection with a gammaherpesvirus closely related to EBV sensitizes the host to a second unrelated immune stimulus that triggers MS-like disease manifestations. Chronic priming of microglia resulting from the initial infection contributes to this process, and prevention of such priming with early antiviral treatment also prevents neuropathology following the second stimulus. EBV infection may similarly sensitize humans to a second stimulus and, if so, treatment of acute EBV infection may avert subsequent MS development.",
"41073405": "ID: 41073405\nTitle: Extracellular vesicles derived EBV tegument protein BRRF2 suppresses cGAS phase separation to promote anti-viral innate immune evasion.\nAbstract: Viral strategies to antagonize the robust host innate immune response have a major function in the pathogenicity of viral infection and virus-associated cancers. Epstein-Barr virus (EBV) infection causes infectious mononucleosis (IM) and several human cancers. While latent EBV can reactivate in some nasopharyngeal carcinoma (NPC) cells, the impact of EBV reactivation on the anti-viral innate immune and immunotherapy response of NPC patients remains incompletely understood. Here, we reveal the function of the EBV-encoded BRRF2 protein as a pivotal regulator of the host immune system. We show that BRRF2, which is secreted via extracellular vesicles (EVs) from NPC cells undergoing EBV reactivation, specifically targets macrophages. It disrupts the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway, which is crucial for innate immunity. BRRF2 inhibits the enzymatic activity of cGAS by interfering with the interaction of cGAS with dsDNA and reducing cGAS-DNA phase separation. Notably, our research shows a marked increase in the levels of BRRF2+ EVs in the bloodstream of NPC patients, which is closely associated with a diminished response to immunotherapy. By identifying BRRF2 as a potential biomarker for immunotherapy resistance, our findings provide deeper insight into the contribution of EBV to viral immunology and suggest further avenues for therapeutic intervention to increase the efficacy of immunotherapy.",
"41207217": "ID: 41207217\nTitle: Emerging and Re-emerging viruses as triggers of human endogenous retrovirus activation: Implications for aging and age-related pathologies.\nAbstract: The human genome contains a substantial legacy of ancient retroviral infections known as Human Endogenous Retroviruses (HERVs), composing 8\u00a0% of our DNA. In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases.",
"41265623": "ID: 41265623\nTitle: Oxymatrine regulates microglia to produce IFN-\u03b2 by activating the STING/TBK1/IRF3 pathway against experimental autoimmune encephalomyelitis.\nAbstract: Oxymatrine is an alkaloid with the property of immunomodulation. Recent studies have demonstrated that oxymatrine inhibits experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), by promoting the production of interferon-\u03b2 (IFN-\u03b2). However, the mechanism through which oxymatrine regulates the production of IFN-\u03b2 remains unclear. The aim of this study was to investigate the pharmacological effects and related molecular mechanisms of oxymatrine in the treatment of EAE through in vivo and in vitro experiments. Oxymatrine alleviated neurological dysfunction, demyelination, and inflammation in EAE mice. It reduced microglia/macrophage infiltration and polarization, lowered pro-inflammatory cytokine levels (iNOS, TNF-\u03b1), and enhanced the expression of IL-10 and IL-27. Additionally, oxymatrine upregulated the STING/TBK1/IRF3 signaling pathway in EAE mice, promoting IFN-\u03b2 production by microglia. Similarly, in LPS-induced BV2 cells, oxymatrine suppressed inflammatory factors and activated the STING/TBK1/IRF3 pathway to enhance IFN-\u03b2 production. Notably, treatment with the STING inhibitor, C176, reversed these effects in both EAE mice and LPS-induced BV2 cells, confirming the pathway's critical role in the mechanism of oxymatrine therapy. Oxymatrine promotes IFN-\u03b2 production in microglia by upregulating the STING/TBK1/IRF3 signaling pathway, thereby alleviating the neurological dysfunction of EAE and reducing pathological and inflammatory events. This study identifies a novel anti-EAE mechanism of oxymatrine: promoting IFN-\u03b2 production in microglia by activating the STING/TBK1/IRF3 pathway. However, it lacks clinical sample verification. If validated later, oxymatrine may provide a more economical, convenient endogenous IFN-\u03b2 induction regimen for MS patients.",
"41386298": "ID: 41386298\nTitle: Sterile innate immune mechanisms in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by the dysfunction and death of susceptible neuronal populations. Increasing evidence has demonstrated that sustained neuroinflammation and activation of innate immune complexes underlie neurodegeneration, worsening disease progression and outcomes. Sterile inflammation (which occurs in the absence of infection) can be triggered by neurodegenerative disease-associated misfolded proteins. These studies highlight the need to decipher the complexities of innate immune signaling mechanisms and their contribution to neuropathology. In this review, we focus on major neurodegenerative diseases that have a well-documented neuroinflammatory component: Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, and frontotemporal dementia. In the context of these diseases, we discuss recent advances in innate-immune mechanisms that have been demonstrated to partake in disease progression and neurodegeneration. These include evolutionarily conserved innate-immune signaling complexes whose uncontrolled activation amplifies neurodegeneration, damaging lipid droplets that accumulate within myeloid cells and prevent their ability to clear toxic protein aggregates, as well as genome-wide studies-implicated genes/proteins. The individual and/or concerted actions of these pathways could be leveraged to rationally target the pathogenesis or progression of neurodegenerative diseases.",
"41459768": "ID: 41459768\nTitle: ETS Translocation Variant 5 Negatively Modulates Innate Immunity to Facilitate Epstein-Barr Virus Reactivation.\nAbstract: Epstein-Barr virus (EBV) is a member of the gamma-herpesvirus subfamily that is prevalent in the human population. There are two phases of EBV infection: latent infection and lytic infection. During lytic reactivation, host innate immune responses are activated to restrict EBV replication. Here, we identified ETS translocation variant 5 (ETV5) as a negative regulator of innate immune responses to facilitate EBV reactivation. ETV5 expression was upregulated by the EBNA1/BRD7 axis, which had been previously described by us, during EBV latent infection. When EBV was induced into lytic replication, the expression of ETV5 was further increased, and ETV5 overexpression dramatically enhanced the lytic replication of EBV. Mechanistically, upon EBV reactivation, the overexpression of ETV5 suppressed the activation of TANK-binding kinase 1 and interferon regulatory factor 3 (IRF3), as well as the transcription of interferon beta (IFNB1) gene and interferon-stimulated genes (ISGs). The effect of ETV5 knockdown could be reversed by an inhibitor of innate immunity pathway. These findings position ETV5 as a critical accelerator of EBV reactivation through immune evasion, revealing new therapeutic targets for managing EBV-associated diseases.",
"41484491": "ID: 41484491\nTitle: Microglia Mitochondrial Metabolism in Neurological Diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), play critical roles in maintaining brain homeostasis and responding to neurological insults. Recent advances have fundamentally reshaped our understanding of how microglial mitochondrial metabolism influences neuroinflammation and disease progression. Single-cell transcriptomics has revealed unexpected metabolic heterogeneity, identifying distinct phenotypes such as disease-associated microglia (DAM) and lipid-laden microglia (LLM) that represent not merely activated states but terminal endpoints of metabolic paralysis. These discoveries converge on a unified pathogenic mechanism: mitochondrial quality control failure leads to mitochondrial DNA release, which activates the cGAS-STING pathway to create an \"epigenetic lock\" that drives sustained neuroinflammation. Interestingly, we highlight that the loss of metabolic flexibility-rather than glycolysis per se-is the true driver of pathology, explaining why the same metabolic shift can be protective during acute injury but pathological when sustained chronically. We critically examine conflicting evidence across Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ischemic stroke, including the puzzling dual roles of glycolysis, controversies surrounding the experimental autoimmune encephalomyelitis (EAE) model in multiple sclerosis research, and the paradoxical worsening of stroke outcomes following microglial depletion. By synthesizing these mechanistic insights with lessons from failed clinical trials, we identify critical translational gaps-including the lack of longitudinal human data and validated biomarkers-and propose a precision medicine framework focused on restoring mitochondrial dynamics and metabolic flexibility in neurological diseases.",
"41638453": "ID: 41638453\nTitle: Buyang Huanwu Decoction alleviates vascular cognitive impairment by inhibiting neuroinflammation via regulation of the p53/cGAS/STING pathway.\nAbstract: Buyang Huanwu Decoction (BYHWD), a traditional Chinese medicine (TCM) formulation renowned for its properties in replenishing qi and promoting blood circulation, corresponds closely with the pathophysiological framework of \"qi deficiency and blood stasis\" observed in vascular cognitive impairment (VCI). Consequently, there is a critical need to validate its therapeutic efficacy and elucidate the pharmacological mechanisms underlying its use in VCI treatment. This investigation aimed to systematically assess the therapeutic effects of BYHWD on VCI and to clarify the molecular mechanisms involved. The bioactive constituents of BYHWD were characterized via UHPLC-MS/MS. A rat model of VCI was established through two-vessel occlusion (2VO). Experimental groups received oral gavage administration of BYHWD at dosages of 6.4, 12.8, and 25.6\u00a0g/kg daily for four weeks, with Ginaton (14.4\u00a0mg/kg) employed as a positive control. Cerebral blood flow was assessed using laser speckle imaging. Cognitive performance was evaluated through the Morris water maze (MWM) test. Histopathological changes in brain tissue were assessed by Nissl and LFB staining. To investigate pharmacological mechanisms, ELISA, immunohistochemistry, Western blot, and immunofluorescence analyses were conducted. Additionally, in vitro studies utilized an oxygen-glucose deprivation (OGD) model in BV2 microglial cells, with intervention by the p53 activator Nutlin-3 to further validate mechanistic pathways. Administration of BYHWD markedly enhanced learning and memory functions, increased cerebral perfusion, and mitigated neuronal loss and white matter injury in 2VO rats. Furthermore, BYHWD significantly inhibited microglial activation and decreased the secretion of pro-inflammatory cytokines. Mechanistic investigations demonstrated that BYHWD downregulated the expression of proteins associated with the p53/cGAS/STING signaling pathway in the 2VO model. In vitro, activation of p53 by Nutlin-3 negated the neuroprotective effects of BYHWD on OGD-induced BV2 cells and concurrently intensified inflammatory responses. BYHWD ameliorates cognitive deficits and neuropathological damage in 2VO rats primarily through suppression of the p53/cGAS/STING signaling cascade and attenuation of neuroinflammation. This study provides strong pharmacological evidence for the early prevention and clinical treatment of VCI.",

This study aimed to investigate the role of neuronal Toll-like receptor 4 (TLR4) in promoting ferroptosis, an iron-dependent cell death pathway, during experimental autoimmune encephalomyelitis (EAE). We leveraged a MOG35-55-induced EAE mouse model (n\u00a0=\u00a010 per group) alongside in vitro LPS-stimulated SH-SY5Y mono- and co-culture systems (n\u00a0=\u00a03 biological replicates) to interrogate the crosstalk between TLR4 signaling and ferroptosis. This link was comprehensively evaluated via biochemical assays, Western blotting, RT-qPCR, co-immunoprecipitation, immunofluorescence analyses, and transmission electron microscopy. Furthermore, we mechanistically dissected the underlying signaling cascades using siRNA-mediated gene silencing and co-immunoprecipitation. Both in vivo and in vitro models recapitulated classical ferroptosis features, including NCOA4-mediated ferritinophagy, lipid peroxidation, and iron overload. Mechanistically, we suggest that neuronal TLR4 activation may provoke the release of mitochondrial DNA into the cytosol, thereby potentially engaging the cGAS-STING axis and precipitating dysregulated iron metabolism. Observations indicate that the TLR4 signaling contributes to ferroptosis even within the complex inflammatory microenvironment of microglia-neuron co-cultures. In EAE mice, pharmacological blockade of ferroptosis via Liproxstatin-1 appeared to ameliorate clinical severity, associated with restored neuronal GPX4 expression in the brain and spinal cord, and concomitantly suppressed lipid peroxidation. This study proposes a specific TLR4-mtDNA-cGAS-STING-NCOA4 signaling cascade that may facilitate neuronal ferroptosis in EAE mice. These findings suggest a novel mechanism of neuronal injury in MS and underscore that targeting this intrinsic neuronal pathway could represent a promising therapeutic strategy to ameliorate progressive neurodegeneration.",

However, the precise molecular mechanisms underlying its antidepressant effects remain to be fully elucidated. This study aimed to characterize the chemical composition of ZZHP and investigate its antidepressant-like effects and underlying mechanisms, specifically focusing on the regulation of Mitochondrial Transcription Factor A (TFAM)-mediated mitophagy and the cGAS-STING innate immune pathway. Chemical constituents of ZZHP were profiled using UPLC-Q-TOF-MS/MS. The antidepressant efficacy was evaluated in vivo using a Chronic Unpredictable Mild Stress (CUMS) mouse model with behavioral batteries (SPT, TST, FST, OFT) and in vitro using corticosterone (CORT)-injured PC12\u00a0cells. Mechanistic explorations involved immunofluorescence, Western blotting, transmission electron microscopy, and co-immunoprecipitation to assess mitochondrial integrity, autophagy flux, and the TFAM-LC3B interaction. Furthermore, TFAM-targeted siRNA transfection and a neuron-microglia co-culture system were employed to verify the molecular targets and intercellular crosstalk. Chromatographic analysis identified 22 bioactive compounds within ZZHP. In CUMS mice, ZZHP administration robustly ameliorated depressive-like behaviors, restored hippocampal neuronal morphology, and attenuated oxidative stress and neuroinflammation. Mechanistically, ZZHP upregulated neuronal TFAM expression and enhanced the formation of the TFAM-LC3B complex, thereby facilitating the autophagic clearance of damaged mitochondria and cytosolic mtDNA. This restoration of selective mitophagy effectively abrogated the activation of the cGAS-STING signaling pathway. Notably, TFAM knockdown in PC12\u00a0cells abolished the neuroprotective and anti-inflammatory effects of ZZHP, confirming TFAM as a critical therapeutic target. Additionally, ZZHP-conditioned neuronal medium promoted the polarization of microglia toward the anti-inflammatory M2 phenotype. These findings indicate that ZZHP exerts potent antidepressant effects by orchestrating TFAM-dependent mitophagy to eliminate immunogenic mtDNA, thereby inhibiting the cGAS-STING inflammatory axis and remodeling the neuroimmune microenvironment.",
"41949651": "ID: 41949651\nTitle: An autoantibody signature predictive for multiple sclerosis: evidence at the protein level and association with histopathological lesion types.\nAbstract: Recently, an autoantibody signature considered to be predictive of multiple sclerosis (MS) has been reported in an article by Zamecnik et al. published in Nature Medicine, which is characterized by immunoglobulin G (IgG) responses to peptides sharing the amino acid motif P-(SA)-x-(SGA)-R-(SN)-(LRKH). These results are highly important, all the more so as the same motif is present also in two proteins expressed by Epstein-Barr virus (EBV), a pathogen that likely plays a key role in MS pathogenesis. However, clinically relevant autoantibody responses often target conformational epitopes, and peptides often differ from their corresponding proteins in terms of conformation. We were therefore interested in whether these findings can be reproduced at protein level and may thus play a role also in vivo. Here, we report findings from complementary experiments employing a microarray covering nearly 10,000 human full-length proteins and using serum and cerebrospinal fluid samples from patients with a histopathologically confirmed diagnosis of MS. Our data show that prominent IgG responses to full-length proteins bearing the P-(SA)-x-(SGA)-R-(SN)-(LRKH) motif can indeed be found in a substantial proportion of MS patients, although considerable inter-patient variability exists in both the type and number of individual responses. Notably, these IgG responses were more pronounced in patients with histopathologically defined pattern II MS (which is characterized by intralesional IgG and complement deposition) and pattern III MS than in patients with pattern I MS in our study. New motif-bearing candidate antigens identified in this study include RBMY2FP, CHMP2B, SRSF8 (SFRS2B), NUS1 (NgBR, Nogo-B receptor), and RTN2. Further studies investigating the diagnostic, pathophysiological, therapeutic, and prognostic implications of this antibody signature, as well as the potential role of cross-reactivity with EBV-suggested by the presence of the motif of interest in both EBV BRRF2 and EBV envelope glycoprotein M-are warranted and may significantly advance our understanding of MS.",

Corosolic acid (CA) has proven lipid-lowering and hepatoprotective effects, yet the underlying mechanism by which CA mitigates MASLD remains unclear. In this study, mice were fed a high-fat diet for 8 weeks to induce MASLD, followed by 8 weeks of CA intervention. We found that CA significantly suppressed weight gain, reduced serum lipid levels, and improved liver function in the HFD-fed mice. Fecal metabolomic analysis showed that CA regulated multiple metabolic pathways including histidine metabolism and altered 10 shared metabolites between feces and serum, such as HAD-Car. 16S rRNA sequencing and fecal microbiota transplantation confirmed that CA reshaped gut microbiota, upregulating beneficial bacteria (e.g., Lachnospiraceae_NK4A136_group) and downregulating harmful strains (e.g., Blautia ).

METHODS: Next generation sequencing of Ig heavy chains (VH) originating from bulk-sorted B cell populations was performed in 33 pwMS and ten healthy controls. All 33 pwMS were examined longitudinally at baseline and six months after treatment with ozanimod, fingolimod, dimethyl fumarate, teriflunomide, cladribine or natalizumab. Ig peptides were obtained longitudinally in a subset of treated pwMS by Ig mass spectrometry, overlapped with VH transcriptomes through nf-core bioinformatics workflow analysis and additionally Ig serum level and anti-Epstein-Barr virus IgG level (EBNA1) were measured. RESULTS: VH repertoires of treatment-na\u00efve pwMS showed a significantly decreased diversity in the double negative B cells and different usage of IGHV genes when compared with healthy controls. Quantitative changes in B cell subsets during treatment were accompanied by qualitative changes in Ig repertoires with a significantly decreased diversity in the naive, memory B cells and plasmablasts during ozanimod treatment. A similar trend was noticeable for all other treatments except natalizumab. No qualitative change in Ig peptides overlapping with Ig transcriptome repertoires was observed. CONCLUSIONS: This study provides first evidence for an altered peripheral Ig repertoire in pwMS. In addition, various treatments seem to shift the composition of B cells towards an increased fraction and activation of the naive B cell pool and a reduced fraction of memory B cells with reduced clonal diversity.",

A self-controlled design was adopted, collecting colorectal tubular adenoma (TA) and paired normal mucosa (NM) from 15 patients with TA. Differentially expressed proteins were screened by DIA proteomics, followed by GO and KEGG enrichment analyses. Immunohistochemistry was performed to detect the expression of SLC30A10, cGAS, STING, p-IRF3, ISG15, and \u03b2-catenin; immunofluorescence double staining was used to observe the co-localization of p-IRF3 and \u03b2-catenin; inductively coupled plasma mass spectrometry (ICP-MS) was employed to determine tissue manganese content. DIA analysis showed that SLC30A10 protein expression was significantly downregulated in TA tissues. Functional enrichment analysis indicated abnormalities in signal transduction, metabolic reprogramming, and nitrogen metabolism in TA tissues. IHC results demonstrated that, compared with NM, TA tissues exhibited reduced expression of SLC30A10, while the expression of cGAS, STING, p-IRF3, ISG15, and \u03b2-catenin was upregulated. Manganese content in TA tissues was also significantly increased. Immunofluorescence revealed enhanced nuclear signals of p-IRF3 in TA cells, with co-localization of p-IRF3 and \u03b2-catenin observed in the nucleus. Downregulation of SLC30A10 in colorectal tubular adenoma is associated with manganese accumulation and alterations in the cGAS-STING pathway, suggesting its potential role in the development and progression of adenoma, a finding with promising research implications.",

However, the development of pharmacological inhibitors for cGAS-STING signaling is currently hindered by lacking cell-specific targeting capability. This study aimed to develop a potent, drug-free nanodevice that specifically targets pulmonary macrophages to modulate the cGAS-STING pathway for ameliorating infection-associated detrimental lung inflammation. Cigarette smoke extract-modified peptide gold nanoparticle hybrids (CSE-P12) were synthesized. Transcriptomic analysis, western blotting, autophagy reporter assays, and confocal microscopy were employed to assess the effects of CSE-P12 on gene expression, STING degradation, autophagic flux, and inflammation. TEM imaging and LC-MS/MS were utilized to elucidate the molecular mechanisms underlying CSE-P12-induced autophagy in macrophages. Finally, the HAdV4-induced pneumonia and CLP-induced sepsis models on wild-type and STING-/- mice were used to evaluate the therapeutic efficacy of CSE-P12 and validate its inhibitory mechanisms on the cGAS-STING pathway. CSE-P12 nanodevices are extensively internalized by macrophages via energy-dependent cellular uptake. This large internalization triggers autophagic degradation of STING, thereby effectively inhibiting the cGAS-STING-mediated interferon responses and inflammation. In the HAdV4-induced viral pneumonia mouse model, intratracheally instilled CSE-P12 effectively targets pulmonary macrophages, suppresses STING activation, and significantly alleviates lung inflammation and injury. The depletion of the pulmonary macrophages abolishes these protective effects. The therapeutic potential of CSE-P12 is further validated in a CLP-induced polymicrobial sepsis mouse model, where it significantly prolongs mouse survival and decreases lung inflammation. CSE-P12 effectively targets pulmonary macrophages and exhibits potent anti-inflammatory activities in viral pneumonia and sepsis-induced acute lung injury by inducing autophagic flux to facilitate STING degradation. This work provides a new paradigm for designing targeted nanotherapeutics to modulate STING activation in inflammatory diseases.",

Hongqi Shenmai Yin (HSY) has been used in clinical practice for many years, can improve cardiac function in MI patients. However, its underlying therapeutic mechanisms remain unclear. This study aimed to determine whether HSY alleviates adverse cardiac remodeling following MI by inhibiting stimulator of interferon genes (STING)-dependent PANoptosis. The MI model was established by ligating the left anterior descending coronary artery (LAD) in rats. Ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS) identified bioactive compounds in HSY. Cardiac function, hypertrophy, and fibrosis were assessed via echocardiography and histological staining. ELISA measured cardiac injury biomarkers, inflammatory cytokines, and oxidative stress markers. Transcriptomic analyses identified potential HSY targets in post-MI remodeling. Molecular docking and surface plasmon resonance (SPR) assessed binding interactions between HSY's key active components and STING. Mechanistic rescue experiments determined whether HSY regulates PANoptosis via STING inhibition. Functional studies were further conducted by transfecting H9c2 cardiomyocytes with lentivirus vectors encoding STING-overexpression. HSY attenuated inflammation, oxidative stress, and adverse remodeling while improving cardiac function post-MI. UPLC-MS identified 107 major HSY constituents. Transcriptomics linked HSY's cardioprotective effects to STING signaling and PANoptosis modulation. Molecular docking and SPR confirmed strong binding affinity between HSY's primary active compounds and STING. Both in vivo and in vitro experiments revealed that HSY suppressed STING-induced ZBP1-PANoptosome assembly, downregulating PANoptosis-associated proteins (p-MLKL, p-RIPK1, p-RIPK3, GSDMD-NT, GSDME-NT, Cle-CASP1, Cle-CASP3, Cle-CASP8) in post-MI remodeling.

Compelling epidemiological studies now demonstrate that EBV infection precedes MS onset and is a necessary precondition for disease development. This is supported by pathology findings revealing EBV-infected B cells within CNS lesions and immunogenetic data linking viral and human genetic susceptibility to MS risk. Mechanistically, EBV appears to act as an upstream trigger that reshapes B cell function, promotes molecular mimicry with CNS antigens, and drives compartmentalized neuroinflammation. In this Review, we synthesize epidemiological, pathological, immunogenetic, and clinical-therapeutic evidence to construct a coherent model of EBV-driven MS pathogenesis. We examine how current MS therapies intersect with EBV biology and discuss the challenges and opportunities in developing EBV-targeted strategies, including vaccines and antivirals, for disease prevention and early intervention. Finally, we highlight key unresolved questions and outline a translational research agenda aimed at intercepting MS through virologically informed approaches.",

DPV infection induces severe immunosuppression, yet the mechanisms by which this pathogen subverts host innate immunity, particularly through manipulation of the host ubiquitin system, remain unclear. The cGAS-STING signaling pathway is a cornerstone of anti-DNA viral immunity. In avian species, where IRF3 has been evolutionarily lost, the transcription factor IRF7 plays a pivotal role in activating type I interferons (IFN-I). Here, we identify duck RNF34 (DuRNF34) as a host E3 ubiquitin ligase that broadly suppresses the duck cGAS-STING pathway by targeting multiple components, including DucGAS, DuSTING, and DuIRF7, for ubiquitination and degradation. Importantly, DPV infection upregulates DuRNF34 expression, which selectively targets DuIRF7 for degradation to facilitate viral replication. Further affinity purification-mass spectrometry (AP-MS) analysis revealed that LORF2, a DPV-specific protein, recruits DuRNF34 to catalyze K11- and K48-linked polyubiquitination of DuIRF7 at lysine residues K51 and K453, leading to DuIRF7 degradation and suppression of IFN-\u03b2 and downstream antiviral genes. Functional validation confirmed that siRNA-mediated knockdown of LORF2 markedly attenuated DPV-induced DuIRF7 degradation and impaired viral replication. Collectively, these findings reveal a novel immune evasion strategy in which DPV hijacks the host E3 ligase DuRNF34 via its unique protein LORF2, thereby targeting DuIRF7 for degradation to subvert innate immunity. This work provides new insights into herpesviral immune evasion and suggests potential targets for therapeutic intervention.",

While acute COVID-19 is generally milder in children due to a more robust innate immune response, the mechanisms driving the persistence of symptoms in PPCC remain incompletely understood and likely multifactorial. This narrative review synthesizes current epidemiological data and explores the \"perfect storm\" of immunological and pathophysiological alterations underpinning the condition. We examine critical hypotheses including a dysregulated immune response characterized by altered T-cell subsets, monocyte activation, and autoantibody production. We discuss the potential role of persistent SARS-CoV-2 viral reservoirs in \"sanctuary sites\" like the gastrointestinal tract and the reactivation of latent viruses such as Epstein-Barr virus (EBV). Furthermore, the review details downstream pathogenic pathways, including vascular endothelial inflammation (thrombo-inflammation), neuroinflammation, and metabolic dysfunctions affecting the mitochondria and tryptophan-kynurenine pathway. Finally, we address the role of microbiome dysbiosis in perpetuating systemic inflammation and the gut-lung axis dysfunction. Given the heterogeneity of clinical presentations, we conclude that PPCC is likely a syndrome of overlapping biological phenotypes. Future research must prioritize identifying these specific biological endotypes to develop targeted diagnostic and therapeutic strategies for the pediatric population.",
"42041941": "ID: 42041941\nTitle: Triple Latency as a Driver of Chronic Inflammation: An Integrative View of HSV, EBV, and CMV Persistence in Immunocompetent Hosts.\nAbstract: Background: Herpes simplex virus (HSV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) establish lifelong latency in sensory neurons, lymphoid tissue, and myeloid-endothelial cells, respectively. A substantial proportion of adults worldwide are infected with all three viruses and may experience concurrent herpesvirus latency, yet they have largely been studied independently. This review examined whether latent and intermittently reactivating herpesviruses share overlapping inflammatory signatures and whether their combined presence contributes to chronic inflammatory burden. Methods: A narrative integrative review was conducted using MEDLINE, Embase, and Google Scholar (inception-October 2025). Evidence from thirty-one cohort studies and mechanistic investigations spanning virology, immunology, neurology, and clinical medicine was synthesized. Results: Herpesvirus reactivation rates ranged from 23% in general Intensive Care Unit (ICU) populations to 85% in severe COVID-19. Concurrent reactivation of multiple viruses occurred in 34-63% of critically ill patients and was associated with worse clinical outcomes. Notably, simultaneous CMV and EBV reactivation independently predicted mortality (adjusted hazard ratio, 3.17; 95% CI, 1.41-7.13). Across infections, overlapping inflammatory biomarkers, including IL-6, TNF-\u03b1, CRP, and PGE2, were consistently elevated, reflecting convergent activation of IFN and NF-\u03baB signaling pathways. Mechanistic studies suggest cross-compartment immune priming, where CMV-driven T-cell exhaustion facilitates EBV reactivation, and viral cytokine signaling enhances HSV-associated neuroinflammation. Conclusions: HSV, EBV, and CMV triple latency may represent an underrecognized contributor to chronic inflammation in immunocompetent hosts. Understanding this multi-virus inflammatory network may inform mechanistic research, biomarker-guided risk stratification, and therapeutic strategies targeting convergent inflammatory pathways. Prospective interventional studies incorporating concurrent multi-virus monitoring are needed to clarify causal relationships.",

Irisin, an exercise-induced myokine, has been reported to exhibit neuroprotective effects, including anti-inflammatory activity and cognitive improvement. To investigate the therapeutic potential of irisin in the experimental autoimmune encephalomyelitis (EAE) mouse model and its effects on microglial behavior along with the underlying molecular mechanisms, we conducted the present study. Results demonstrated that irisin treatment significantly alleviated EAE severity, evidenced by reduced disease incidence, attenuated weight loss, and improved neurological scores. Histopathological analysis revealed that irisin suppressed inflammatory cell infiltration and reduced demyelination in spinal cord tissues. Furthermore, irisin inhibited microglial overactivation and promoted a phenotypic shift from the pro-inflammatory M1 to the anti-inflammatory M2 microglia. Mechanistically, immunofluorescence co-localization and Western blot analyses confirmed that these beneficial effects were mediated via suppression of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway, as indicated by downregulation of STING and phosphorylated interferon regulatory factor 3 (p-IRF3) expression. Collectively, these findings indicate that irisin alleviates neuroinflammation and exerts neuroprotective effects in EAE by modulating microglial activity through inhibition of the cGAS-STING pathway, underscoring its potential as a novel therapeutic candidate for MS.",

In vitro 2D monolayer cell cultures and in vivo transgenic animal models have been the primary tools for investigating mechanisms of neurodegenerative diseases. However, the ineffectiveness of these models in translating outcomes into human pathophysiology, necessitates innovative approaches to bridge the translational gap. In this review, we focus on the intricate pathogenic processes by which environmental toxicants and viral infections trigger neurodegeneration. The growing significance of three-dimensional (3D) brain organoids (BOs) derived from induced pluripotent stem cells (iPSCs) can be used as a groundbreaking platform for examining neurodegenerative pathways induced by exposure to environmental toxicants and viral infections. It also addressed how BO's overcomes the fundamental limitations of traditional models, such as 2D cultures and animal models, thereby creating novel opportunities for the mechanistic study of multifactorial neurodegeneration and the development of therapeutic interventions.",

These viruses may induce autoimmune reactions by molecular mimicry, leading to damage to self-epitopes in the central nervous system (CNS). This study seeks to explore the common pentapeptides present in EBV and HHV-6 viral antigens alongside various CNS-related proteins via molecular mimicry. Additionally, it will assess the immunogenicity of these shared pentapeptides in T and B cells. Sequence alignment was conducted to assess molecular mimicry between 32 EBV and HHV-6 antigens and 10 CNS autoantigens. Protein sequences were obtained from UniProt, structural homology was analyzed using AlphaFold and PyMol, and shared pentapeptides were identified with Alignmentaj. Immunogenicity was assessed via the Immune Epitope Database (IEDB) for potential T- and B-cell activation. A total of 91 mimicry pentapeptides were identified between viral antigens (42 EBV and 49 human HHV-6), and 10 CNS proteins. Notably, synapsin (SYN)1 exhibited the highest mimicry, sharing 13 pentapeptides with (7 with EBV and 6 with HHV-6) viral antigens such as EBV nuclear antigen (EBNA)1, EBNA6, latent membrane protein (LMP)1, and early antigen diffused (EA-D). Myelin proteins, including myelin-associated glycoprotein with 12 shared pentapeptides, myelin basic protein with 9, and myelin-oligodendrocyte glycoprotein with 5, displayed immune cross-reactivity with EBV/HHV-6 antigens. EBNA1, EBNA2, EBNA6, LMP1, LMP2, EA-D, and BLLF1 structurally resemble CNS autoantigens and act as immunoreactive epitopes for human T and B cells. Except for EBNA2 and protein U94, all share immunogenic pentapeptide sequences with SYN1. Shared pentapeptides suggest a link between viral infections and CNS autoimmunity. Further research is needed to clarify molecular mechanisms and explore targeted therapies to mitigate virus-induced neuroinflammation.",

Increasing evidence indicates that ISG15 and its conjugation system (ISGylation) extend far beyond canonical antiviral activity to critically regulate neuroinflammatory responses in the central nervous system (CNS), contributing to the pathogenesis of viral encephalitis, neurodegenerative disorders, autoimmune demyelination, and certain neuropsychiatric conditions. Mechanistically, ISG15 functions in both conjugated and free forms, exerting context-dependent effects on key inflammatory pathways, including JAK-STAT , NF-\u03baB, inflammasome activation, and cGAS-STING signaling. Through these coordinated actions, ISG15 acts as a molecular rheostat that fine-tunes neuroimmune responses, with outcomes determined by cell type, disease stage, and the balance between intracellular ISGylation and extracellular ISG15 signaling. This functional versatility underscores its translational relevance, as multiple components of the ISGylation machinery, such as the E1 enzyme UBE1L, the E2 enzyme UBE2L6, the E3 ligase HERC5, and the deISGylating Ubiquitin-specific protease 18 (USP18), representing emerging druggable nodes within interferon-driven networks. In this review, we summarize current insights into the molecular and cellular roles of ISG15 in neuroinflammation, highlight its dual protective and pathogenic functions, and discuss therapeutic strategies and future directions for targeting ISG15-related pathways in CNS diseases.",

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

The pyroptosis of colonic epithelial cells (CECs) disrupts the colonic barrier, and its inhibition might be a therapeutic approach for ulcerative colitis (UC), but the mechanisms are not fully understood. A DSS-induced UC model was established to assess the level of colonic epithelial cell pyroptosis. 16S rDNA sequencing and LC\u2012MS/MS were applied to screen potential candidate bacterial species and metabolites. The roles of target metabolites were evaluated in vivo using GSDMD-knockout mice. FHC cells treated with LPS\u2009+\u2009ATP were used as a cellular model of pyroptosis, and the underlying molecular mechanism was explored mainly by siRNA transfection and lentivirus infection. We found that DSS-treated mice exhibited increased levels of pyroptosis in the colon. Fecal microbiota transplantation (FMT) significantly suppressed mucosal inflammation and CEC pyroptosis, accompanied by increased levels of butyrate-producing bacteria and butyrate in feces. Butyrate treatment alleviated DSS-induced colitis in mice. Moreover, GSDMD knockout mitigated DSS-induced colitis in mice, whereas a butyrate intervention failed to further ameliorate colitis in GSDMD-knockout mice. Mechanistically, we found that butyrate significantly inhibited LPS\u2009+\u2009ATP-induced pyroptosis by activating its receptor, aryl hydrocarbon receptor (AhR), in FHC cells, while silencing AhR suppressed this effect. The overexpression of cGAS in FHC increased the level of pyroptosis, whereas the administration of butyrate inhibited the activation of the cGAS-STING pathway. Treatment with a cGAS inhibitor significantly reversed the increase in pyroptosis caused by AhR knockdown in pyroptotic FHC cells. Gut microbiota-derived butyrate levels were increased after FMT. Butyrate suppressed the proinflammatory cGAS-STING-NF-\u03baB signaling axis via AhR to inhibit CEC pyroptosis and thereby alleviate UC.",

Herpes simplex virus type 1, human immunodeficiency virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, influenza, SARS-CoV-2, West Nile virus, and Zika virus each enter or engage the brain through distinct routes, yet converge on four shared molecular pathways that selectively damage hippocampal circuits: mitochondria-associated membrane (MAM) dysfunction, chronic neuroinflammation, blood-brain barrier (BBB) disruption, and impaired CREB-BDNF signaling. These pathways specifically compromise the dentate gyrus, CA3, and CA1 subfields, producing predictable deficits in pattern separation, associative retrieval, and temporal memory binding. Antiretroviral and antiviral therapies suppress viral replication but fail to reverse organelle-level dysfunction, leaving most hippocampal injury unaddressed. Emerging plasma biomarkers, p-tau217, neurofilament light chain, and GFAP, combined with hippocampal subfield MRI, now enable mechanistic stratification before irreversible circuit loss occurs. This review proposes, as a unifying hypothesis, that virus-associated memory impairment represents a convergent hippocampal syndrome driven by shared downstream pathways, and that combination therapies targeting these pathways simultaneously offer greater therapeutic promise than pathogen-specific approaches alone. The evidentiary basis for this framework varies across pathogens and conditions; direct mechanistic evidence, mechanistic analogy, and preclinical data are distinguished throughout.",

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

To map the molecular consequences of PI(3,5)P2 insufficiency in the brain, we performed quantitative proteomic and transcriptomic analyses of three mouse lines bearing distinct loss-of-function mutations in Fig4 or Vac14, examining the brain at the presymptomatic and end stages. Strikingly, profound neuroinflammation was already present at postnatal day 5 (before significant neurodegeneration), characterized by complement activation, interferon signaling, and parenchymal infiltration of peripheral myeloid cells and T-cells. Isolated mutant microglia exhibited a markedly pro-oxidative transcriptional state with elevated reactive oxygen species, a partly non-cell-autonomous phenotype, being present in microglia from mice with conditional Fig4 inactivation in just neurons and astrocytes. Comparison of early (P5) and late (P25) proteomics data revealed that PI(3,5)P2 insufficiency impairs developmental remodeling of the brain proteome: proteins typically upregulated during postnatal maturation failed to accumulate, implicating lysosomal function in neurodevelopment. We identify coordinated elevation of p53, Fas receptor, inflammatory caspases, Gasdermin D, RIPK1, and ZBP1, consistent with multifactorial inflammatory cell death with features of apoptosis, pyroptosis, and necroptosis. Many of the dysregulated proteins are encoded by genes mutated in lysosomal storage disorders, ALS, CMT, Alzheimer's and Parkinson diseases, extending the pathogenic relevance of PI(3,5)P2 insufficiency. Together, these findings establish that early neuroinflammation is a defining - and likely initiating - feature of neurodegeneration caused by disruption of lysosomal PI(3,5)P2.",

Here we summarize evidence that sex hormones, sex-chromosome effects and immune-glial interactions shape key components of the secondary injury cascade, including blood-spinal cord barrier (BSCB) disruption, neuroinflammation, oxidative stress, cell death and remyelination. Estrogens and progesterone generally support barrier stabilization, temper leukocyte infiltration, bias microglia/macrophages toward reparative programs, and promote neurotrophin signaling and myelin repair. In males, post-injury androgen deficiency together with stronger early innate immune activation may exacerbate oxidative damage, demyelination and scar formation, potentially limiting plasticity. Clinical evidence remains limited and confounded, but available data support the need for adequately powered, sex-stratified trials, particularly for time-sensitive hormonal and immunomodulatory interventions. Incorporating sex as a biological variable in experimental design and translation may improve target selection, dosing and therapeutic windows for SCI.",

Neuroinflammation is a critical driver of disease progression and represents a promising target for intervention. Emerging evidence highlights lactate as a signaling metabolite that regulates inflammatory responses through protein lactylation. Given the involvement of 14-3-3 proteins in PD pathogenesis, we investigated whether lactate confers neuroprotection by promoting 14-3-3 lactylation and modulating neuroinflammatory signaling in PD. A rat model of PD was induced by subcutaneous injection of Rotenone (ROT) into the dorsal cervical region. Lactate was administered intracerebroventricularly. Motor function was assessed using open field, grid, and suspension tests. TH-positive neurons in the substantia nigra were evaluated by immunohistochemistry. The lactylation of 14-3-3 proteins and their interaction with NLRP3 were examined by co-immunoprecipitation (Co-IP). Mitochondrial localization of GSDMD was visualized by immunoelectron microscopy. The cytosolic mtDNA was assessed using qPCR. NLRP3 inflammasome components, the cGAS-STING pathway, and mitochondrial GSDMD were analyzed by western blotting. Levels of inflammatory cytokines and cGAMP were quantified by ELISA. Lactate ameliorated motor deficits and dopaminergic neuron loss in ROT-treated rats. Lactate increased 14-3-3 lactylation and enhanced 14-3-3 binding to NLRP3, accompanied by reduced NLRP3 inflammasome activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppressed cGAS-STING pathway activation. Lactate exerts neuroprotective effects in PD through a mechanism associated with enhanced 14-3-3 lactylation, reduced NLRP3/GSDMD pathway activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppression of cGAS-STING signaling.",

Typically occurring in young and middle-aged individuals, untreated MS can have high rates of disability and recurrence, thereby imposing a significant burden on the patient, their family, and society. Many factors are implicated in the etiology of MS, with the relationship between Epstein-Barr Virus (EBV) infection and the development of MS being the subject of extensive research recently. When the human body experiences a decline in immune function, it may trigger reactivation of EBV, and this reactivation is also believed to increase the risk of onset or relapse of MS. Currently, the phenomenon of cross-reactivity resulting from molecular mimicry following EBV infection (including reactivation status) is theorized as a contributing etiology. EBV-mediated abnormalities in T cells and B cells also play a key role in the development of MS. However, the underlying mechanisms have not been thoroughly understood. Meanwhile, the limited availability of effective treatment options for MS, in particular MS progression, underscores the urgent need for novel therapeutic strategies. Here, we discuss the pathophysiological mechanisms underlying MS, specifically emphasizing the relationship between EBV infection and the disease pathology. Furthermore, we introduced relevant pharmacological targets in order to propose a broader range of therapeutic alternatives for individuals diagnosed with MS.",

Plasmacytoid dendritic cells (pDCs) are thought to play a central role in disease pathogenesis following the dysregulated and sustained production of type I interferon (IFN-I), leading to widespread immune system activation and chronic inflammation, resulting in organ and tissue damage characteristic of lupus. While treatment of lupus has shown success with approaches that inhibit the IFN pathway/IFN-I production, targeting pDCs is of great interest due to their accumulation in lesional tissues and key role in IFN-I production. However, SLE and CLE pathogenesis is clouded by unknowns including limited understanding of the pathophysiological loss of IFN pathway negative feedback, the complexity of IFN production by non-pDC cells (including pDC plasticity and role of different subsets/states), the role of other cytokines and chemokines in disease pathogenesis, and differences in pDC activation and downstream effects in SLE and CLE. Conceivably, different IFN-I-producing cells may be important in different organs, patients, and disease stages. As understanding of the role of pDCs in IFN-I production evolves, there is great potential to develop more targeted and effective treatments that can enhance patient outcomes to ensure pathophysiological and chronic inflammation is negated while maintaining physiological immunity to infection.",

While its pathogenesis remains unclear, ferroptosis-an iron-dependent form of cell death driven by lipid peroxidation-has emerged as a key mechanism in neurodegeneration. This review proposes that aging creates a ferroptosis-prone environment in the brain through iron dyshomeostasis, impaired antioxidant defenses, and enrichment of polyunsaturated fatty acids, and that surgical trauma and anesthetic exposure may trigger ferroptosis by activating interconnected pathways such as neuroinflammation, blood-brain barrier disruption, and oxidative stress, leading to neuronal injury in cognition-critical regions like the hippocampus. However, the available evidence is largely correlative, and whether ferroptosis acts as a proximal driver of neuronal death or as a late consequence of pre-existing damage remains undetermined. We dissect the core molecular machinery (GPX4, ACSL4, NCOA4, Nrf2) and emerging regulators (MD2/Hepcidin, CPT1A, RUNX1/RBM47/cGAS-STING, miRNAs, mitophagy, gut microbiota-exosome axis). Therapeutic strategies including iron chelators, lipophilic antioxidants, natural products, physical therapies, and nanomaterials are reviewed, but most remain preclinical.

Emerging evidence suggests that inflammaging is not merely a background feature of aging but an active pathogenic driver of AD, accelerating amyloid-\u03b2 accumulation, tau hyperphosphorylation, and synaptic failure. This review synthesizes the molecular circuitry connecting inflammaging to AD, detailing the synergistic roles of the NLRP3 inflammasome, impaired autophagy, TREM2 signaling, and the cGAS-STING pathway. Furthermore, we critically evaluate pharmacological strategies designed to disrupt these cascades, including specific NLRP3 inhibitors, senolytic agents, and autophagy enhancers.

Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction. Targeting B.p and acetate may offer a promising therapeutic strategy for neuroprotection in OSA.",

Here, we identify the histone acetyltransferase KAT7 (HBO1) as a central epigenetic regulator that links chromatin remodeling to mitochondrial immune activation. KAT7 and its histone mark H3K14ac are elevated in microglia from 5\u00d7FAD mice and human AD brains. Integrative transcriptomic and epigenomic analyses reveal that KAT7 activates transcription of cytidine/uridine monophosphate kinase 2 (Cmpk2), a mitochondrial kinase essential for mtDNA synthesis. Loss of KAT7 reduces Cmpk2 expression, impairs mtDNA replication and release, and consequently suppresses cyclic guanosine monophosphate-AMP synthase (cGAS)-stimulator of interferon genes (STING) and NLRP3 signaling. Importantly, both microglia-specific deletion and pharmacological inhibition of KAT7 mitigate cytosolic mtDNA-induced neuroinflammation, decrease \u03b2-amyloid burden, restore synaptic plasticity, and improve cognitive function in 5\u00d7FAD mice. Together, these findings uncover an epigenetic-mitochondrial axis sustaining microglial pathogenicity and establish KAT7 as a potential therapeutic target for AD.",

This review elucidates the molecular mechanisms underlying the immunomodulatory effects of NPs, their associated physiological outcomes, and the core structure-activity relationships. Mechanistically, NPs exert anti-inflammatory or immunostimulatory functions by modulating immune organ indices, activating or suppressing various immune cells (e.g., macrophages, dendritic cells, and NK cells), and regulating pivotal immune signaling pathways, including the TLR-NF-\u03baB/MAPK, JAK-STAT, and cGAS-STING pathways. Notably, NPs can indirectly modulate systemic inflammation by remodeling gut microbiota composition and its metabolites (e.g., short-chain fatty acids and tryptophan derivatives). In terms of applications, leveraging these immunomodulatory properties, NPs demonstrate considerable potential in maintaining intestinal homeostasis, ameliorating neuroinflammation-related disorders, exerting anti-cancer effects, and alleviating allergic diseases. Furthermore, this review examines the structural determinants of NPs' immunomodulatory potency, including molecular weight, monosaccharide composition (with a focus on mannose, arabinogalactans, and uronic acids), chemical modifications (such as acetylation, phosphorylation, and sulfation), and degree of branching. Finally, the review outlines the shortcomings of current research and suggests future research directions, proposing that future studies should shift from \"discovery and characterization\" to \"rational design and synthesis\".",

Disrupting this axis requires precise antioxidant delivery to neuronal mitochondria, a major therapeutic hurdle. Here, we uncover that the natural flavonoid quercetin (Quer) possesses an intrinsic ability to bind mitochondrial outer membrane proteins, revealing its unexploited potential as a natural mitochondrial-targeting ligand. Leveraging this discovery, we engineered an ultrasmall mitochondria-targeting cascade nanozyme through coordination-driven self-assembly of the natural flavonoid Quer with Fe3+. MCN currently generates Fe2+/Fe3+ dual-valence centers that confer potent, superoxide dismutase-catalase cascade catalytic enzyme activities. We further confirmed that the MCN traverse the compromised blood-brain barrier, localize within the ischemic brain, and are selectively delivered to neuronal mitochondria in a rodent stroke model. Through its cascade elimination of key ROS, MCN stabilizes mitochondrial function and prevents mtDNA leakage. By blocking the released mtDNA from activating the cGAS-STING pathway in microglia, MCN reprograms the neuroinflammatory microenvironment and robustly attenuates brain injury, leading to significant functional recovery. This work establishes a paradigm of transforming inherent bioactivity of natural products into targeted catalytic nanomedicines, offering a precise therapeutic strategy for mitochondrial-centric diseases.",

While type I interferon signatures are biomarkers in several autoinflammatory diseases, their role in Blau syndrome remains unclear. We assessed the interferon score in 11 patients with Blau syndrome and correlated it with disease activity. Our results demonstrate that type I interferon signatures were detected in only a minority of patients and showed no significant correlation with clinical disease activity, inflammatory markers, or treatment response. These findings suggest that type I interferon signatures are not useful biomarkers for disease monitoring in Blau syndrome, highlighting the need to identify alternative biomarkers reflecting NOD2-mediated inflammatory pathways.",

Emerging evidence indicates that biological sex is an important determinant of mitochondrial function, in part through the regulatory effects of sex hormones on mitochondrial biogenesis, oxidative phosphorylation, reactive oxygen species production, and quality control mechanisms. Estrogen, testosterone, and progesterone differentially modulate mitochondrial dynamics, substrate utilization, antioxidant capacity, and immune signaling, resulting in distinct mitochondrial phenotypes that may influence disease susceptibility across the lifespan. In this review, we synthesize current knowledge on the mechanistic basis of sex differences in mitochondrial function and highlight mitochondria as key mediators linking endocrine signaling to immunometabolic regulation. We discuss how mitochondrial-derived signals, including mitochondrial reactive oxygen species, mitochondrial DNA release, and cardiolipin exposure, activate inflammatory pathways such as NF-\u03baB, cGAS-STING, and NLRP3 inflammasome signaling. These pathways may contribute to chronic inflammation, gut barrier dysfunction, and systemic metabolic disruption. We further examine the impact of major endocrine transitions, including pregnancy, the postpartum period, menopause, and androgen imbalance in conditions such as polycystic ovary syndrome, on mitochondrial function and disease risk. Particular emphasis is placed on the gastrointestinal tract as a metabolically active and mitochondria-dependent interface, where mitochondrial dysfunction may contribute to epithelial barrier disruption, microbial dysbiosis, and systemic inflammation. Finally, we discuss emerging therapeutic strategies targeting mitochondrial function, including exercise, hormone-based therapies, mitochondria-targeted antioxidants, and interventions aimed at improving mitochondrial quality control. Understanding sex-specific mitochondrial regulation may provide a framework for improved endocrine stratification, mitochondrial phenotyping, and precision medicine approaches across diverse clinical contexts.",
"42288132": "ID: 42288132\nTitle: The leaked mitochondrial DNA activated the cGAS-STING signaling pathway and exacerbated the motor dysfunction in mice caused by MPTP.\nAbstract: Parkinson's disease (PD) is the fastest-growing neurological disorder worldwide, outpacing even the rate of population aging. The Global Burden of Disease Study estimated that more than 10 million individuals were affected in 2020, a figure projected to double by 2040. Pathologically, PD is characterised by the progressive degeneration of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNc). Although early mechanistic work centred on gross anatomical changes and neuronal injury, converging evidence now positions neuroinflammation as an early and causal driver of DA neurodegeneration across the entire PD continuum. While cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING)-dependent innate immune signaling has been implicated in several neurodegenerative disorders, its contribution to PD has remained undefined. Here, using complementary in vitro and in vivo PD models, we demonstrate that mitochondrial stress triggers mitochondrial DNA (mtDNA) leakage into the cytosol, thereby activating the cGAS-STING pathway and precipitating SNcDA neuronal loss and overt motor dysfunction. Genetic knockdown of STING markedly attenuated DA neuronal demise and preserved motor performance, identifying STING-mediated neuroinflammation as a critical mediator of DAergic neurodegeneration in MPTP-induced motor deficits. Collectively, our data indicate that selective inhibition of the cGAS-STING inflammatory cascade robustly mitigates MPTP-induced nigrostriatal DA neurodegeneration and motor deficits in mice, and nominate this pathway as a tractable therapeutic target for disease-modifying intervention in PD.",

Current treatments help control inflammation but have limited success in progressive stages and repairing nerve damage. This review aims to summarize new therapies for MS that target both inflammation and neurodegeneration beyond traditional immunosuppressive drugs. We conducted a thorough literature search to summarize key findings from original studies, including clinical trials investigating novel MS treatments such as Bruton's tyrosine kinase (BTK) inhibitors, CAR T-cell therapy, vaccines targeting Epstein-Barr virus (EBV) and specific antigens, drugs promoting remyelination, monoclonal antibodies, stem cell therapy, sphingosine-1-phosphate receptor modulators, cytokine blockers, gut microbiome interventions, and nanotechnology-based drug delivery. Emerging therapeutic strategies in MS increasingly target mechanisms beyond conventional immunosuppression, including B-cell and microglial modulation, immune tolerance induction, remyelination, cytokine signaling, microbiome regulation, and enhanced central nervous system drug delivery. BTK inhibitors and S1P receptor modulators demonstrated anti-inflammatory activity in clinical trials, although some agents failed to show superiority over established therapies. Cell-based therapies, including CAR T-cell therapy and stem cell transplantation, showed early promise in refractory disease but remain limited by safety concerns and insufficient long-term data. Remyelination-promoting agents and EBV-targeted immunotherapies demonstrated encouraging preliminary findings; however, many approaches remain in preclinical or early-phase clinical stages. Nanotechnology-based delivery systems and microbiome-directed therapies represent emerging areas with potential translational relevance. Emerging therapies in MS reflect a growing shift toward mechanism-based and potentially personalized therapeutic strategies. Although several approaches demonstrate promising preclinical and early clinical results, many remain investigational, and further large-scale studies are required to establish long-term efficacy, safety, and clinical applicability.",

How viral persistence, immune responses, and regional CNS T-cell architecture relate to cognitive functioning remains unclear. We performed a cross-sectional, multi-compartmental immune-genomic study in 12 people with HIV on long-term viral suppression enrolled in the Last Gift rapid autopsy program. Quantitative HIV reservoir measures (total-episomal DNA, unspliced-multiply spliced RNA) and paired \u03b1\u03b2 T-cell receptor repertoire (TCRR) sequencing were performed in peripheral blood mononuclear cells and five CNS regions: hippocampus, frontal motor cortex, basal ganglia, occipital cortex, and spinal cord. Cognitive performance was assessed within one year of death. Tissue-resolved associations between cognition and HIV reservoir, TCRR architecture (richness, diversity, clonality), and pathogen-specific T-cell clonotypes (HIV, CMV, EBV, and riboflavin derivatives) were evaluated using participant-clustered multivariable models. False discovery rate was applied. HIV DNA and RNA were detectable across all tissues but were not associated with cognitive performance or TCRR metrics. Peripheral TCRR architecture was unrelated to cognition, whereas higher TCRR richness and diversity in the hippocampus and spinal cord were associated with worse verbal, motor, and attention/working memory scores. Higher TCRR richness in the spinal cord was also associated with better recall. T-cell receptor clonotype frequency distributions differed across CNS regions, consistent with regional immune compartmentalization. Epitope-inference analyses revealed pathogen-dependent associations: higher number of HIV-specific T-cell clonotypes in the basal ganglia was associated with better global and attention/working memory scores, whereas riboflavin derivative-specific clonotypes in frontal motor cortex were associated with better motor performance. CMV-specific clonotypes showed nominal associations with worse learning and memory. CNS-localized T-cell receptor architecture and antigenic imprinting related more closely to neurocognitive variability than quantitative measures of HIV persistence under viral suppression, highlighting regional specialization of T-cell responses as a potential correlate of brain health.",
"42309183": "ID: 42309183\nTitle: cGAS-STING signaling pathway: a central pathological mechanism and emerging therapeutic target for postoperative cognitive dysfunction.\nAbstract: Postoperative cognitive dysfunction (POCD) is a prevalent neurological complication in older patients following surgery. However, the upstream molecular triggers of perioperative neuroinflammation, a key factor in its pathogenesis, remain insufficiently understood. This review systematically examines the emerging evidence implicating the cGAS-STING signaling pathway as a potentially central mediator in the pathological progression of POCD. Integrating recent advancements, we outline a critical pathological cascade in POCD: perioperative stressors, including anesthesia and surgical trauma, induce mitochondrial injury, resulting in the release of mitochondrial DNA (mtDNA) into the cytosol. This leaked mtDNA functions as an endogenous danger signal, activating the cGAS-STING pathway in brain microglia. Activation of this pathway drives neuroinflammation, characterized by proinflammatory (M1-like) microglial polarization, regulated cell death (e.g., pyroptosis), and a self-perpetuating cycle of mitochondrial dysfunction, ultimately leading to neuronal damage and cognitive decline. We propose the mtDNA-cGAS-STING axis as a candidate pivotal link between perioperative stress and the neuropathology of POCD, based on converging preclinical evidence. Therapeutic strategies targeting this pathway, such as cGAS-STING inhibition or the promotion of mitophagy, have shown significant neuroprotective effects in preclinical studies. These findings offer promising avenues for the prevention and treatment of POCD and highlight potential implications for perioperative neuroprotection in older adults.",
"42321474": "ID: 42321474\nTitle: TLR7 in systemic lupus erythematosus: genetics and emerging therapies.\nAbstract: Systemic lupus erythematosus (SLE) is a disease with considerable unmet treatment needs. Endosomal nucleic acid sensing by Toll-like receptor 7 (TLR7) is emerging as a key pathogenic pathway. Gain-of-function mutations in the genes encoding TLR7 and its chaperone UNC93B1 can cause monogenic childhood-onset SLE; rare variants in proteins that regulate ligand availability or downstream signalling proteins also contribute to disease. TLR7 variants can increase the affinity of this receptor for its ligands and can alter binding to endogenous antagonists. Both self RNA-protein complexes and viruses have been implicated in TLR7 activation. Key pathogenic mechanisms include breakdown in B cell tolerance and autoantibody production and type I interferon secretion. Although current therapies such as B cell-depleting chimeric antigen receptor\u00a0(CAR) T cells and anifrolumab (anti-type I interferon receptor) offer benefit, they are limited by high costs and lack of oral options. In this context, TLR7 has emerged as a promising therapeutic target. Phase II trials of an oral dual TLR7-TLR8 antagonist show durable suppression of the interferon signature in all patients, indicating that TLR7 and TLR8 drive this signature in SLE. This treatment has shown clinical benefit for SLE and cutaneous lupus erythematosus, although the primary endpoint (a dose-response effect) was only met in cutaneous lupus erythematosus. Thus, TLR7-TLR8 antagonists might reshape SLE treatment, alone or in combination with other drugs.",

This study sought to determine whether cGAS-STING-mediated microglial activation and aberrant synaptic pruning underlie sevoflurane-induced cognitive deficits and to assess how environmental conditions modulate these processes. Neonatal mice underwent sevoflurane exposure followed by rearing in enriched (EE) or impoverished (IE) environments. Cognitive function, synaptic structure, microglial activity, mitochondrial status, and cGAS-STING signaling were evaluated using behavioral tests, immunostaining, biochemical assays, and pharmacological inhibition. Sevoflurane exposure induced cognitive impairment, microglial overactivation, mitochondrial dysfunction, and excessive synaptic pruning resulting from microglial overactivation. EE mitigated these abnormalities by preserving mitochondrial integrity and reducing mtDNA-driven cGAS-STING activation, thereby preventing the microglia-mediated imbalance in synaptic pruning and improving cognitive outcomes. In contrast, IE exacerbated mitochondrial injury, aggravated synaptic loss, and further worsened cognitive impairment. Sevoflurane disrupts neurodevelopment through a mitochondria-cGAS-microglia-synapse pathway. Environmental enrichment offers significant neuroprotection, highlighting both cGAS-STING signaling and early-life environmental modulation as promising targets for preventing anesthesia-related neurodevelopmental injury.",
"42323525": "ID: 42323525\nTitle: Lactylation: a novel post-translational modification for cGAS-STING pathway.\nAbstract: Lysine lactylation (Kla) is a lactate-derived post-translational modification that has emerged as a critical metabolic-epigenetic regulator linking cellular metabolic states to innate immune signaling. The cGAS-STING pathway, a central cytosolic DNA-sensing mechanism essential for antiviral defense, antitumor immunity, and inflammatory regulation, is profoundly influenced by the metabolic milieu. However, the precise role of lactylation in modulating this pathway remains to be systematically synthesized. This review aims to comprehensively analyze the molecular mechanisms by which lysine lactylation regulates the cGAS-STING signaling axis, and to discuss the pathophysiological implications and therapeutic potential of targeting this modification in diseases ranging from autoimmunity and neuroinflammation to cancer. A comprehensive review of the relevant literature was conducted to summarize the biochemical basis of lactylation (including writers, erasers, and readers) and to systematically examine emerging evidence demonstrating direct and indirect regulation of cGAS-STING components by lactylation. Studies involving site-specific modifications, disease models, and therapeutic interventions were collated and analyzed. Lactylation directly targets core pathway components-cGAS at residues such as K21, K131, K156, K162, K275, and K409, and STING-altering their stability, enzymatic activity, DNA-binding capacity, phase separation, and downstream signaling outputs. Depending on context, lactylation exerts dual effects: it stabilizes cGAS and amplifies type I interferon responses in autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis) and hypoxic-ischemic encephalopathy, but promotes cGAS degradation or suppresses STING activity in cancer (lung adenocarcinoma, glioblastoma) and neuropathic pain, thereby facilitating immune evasion or pain sensitization. Indirectly, lactylation modulates cytosolic DNA ligand availability by influencing mitochondrial DNA release (via HMGB1, VDAC1, Arg1, DRP1) or DNA repair (via KU70). The discovery of specific lactyltransferases (AARS1/2, p300) and delactylases (SIRT1-3, HDAC1-3) establishes lactylation as a dynamic, enzymatically controlled process. Lactylation functions as a pivotal metabolic-immune checkpoint that fine-tunes cGAS-STING signaling in a cell-type- and disease-specific manner. Targeting the lactylation regulatory axis-by inhibiting pathogenic lactylation to restore anti-tumor immunity or enhancing it to dampen deleterious inflammation-offers a novel immunometabolic therapeutic strategy for autoimmune disorders, chronic infections, neurodegeneration, and cancer.",

The different cell types and varying degrees of regulation of STING may lead to a paradoxical effect on pain and emotions in the neuropathic pain model. Up to now, whether STING modulates neuropathic pain in PrL neurons via ER-phagy is still unknown. In this study, we investigated the effect of ER-phagy in the prefrontal cortex (PrL) on neuropathic pain. We administered 4-phenylbutyric acid, tunicamycin, 3-methyladenine, and rapamycin to evaluate the interaction between endoplasmic reticulum (ER) stress and autophagy in the PrL of SNL (spinal nerve ligation). We injected AAV to investigate whether ER-phagy modulated pain and emotional behaviors. We further explored whether STING and its pathway as a modulation target for ER-phagy to participate in the pain process. We injected 2'3-cGAMP and RU521 to modulate the cGAS/STING pathway in ER-phagy in SNL mice. Moreover, we modulated STING expression and regulated the levels of ER-phagy and the interaction between STING and LC3 in neurons through PrL AAV injections. The data indicated that ER-phagy alleviated the excessive ER stress induced by SNL in PrL through the cGAS/STING pathway. Regulating ER-phagy in PrL neurons through AAV tools altered pain and emotion-related behaviors. In addition, regulating STING in PrL neurons altered the comorbidity of pain and emotion. Importantly, the binding interaction between STING and LC3 in PrL neurons provides a novel target for PrL ER-phagy. Enhanced ER-phagy of PrL neurons provides analgesic, anti-anxiety, and antidepressant effects through modulating STING in SNL mice.",

The cGAS-STING pathway is involved in immune modulation. We propose to clarify the specific function of this pathway in CD4+ T cells and its potential contribution to the development of the pathogenesis of PD. We screened common differential proteins in peripheral and midbrain CD4+ T cells from PD mice by proteomic analyses and defined the common upregulated differential protein Myosin VI (MYO6) as a target protein by Protein-Protein Interaction (PPI) analysis. The expression of MYO6 and cGAS-STING pathway proteins was assayed by western blot. The validation experiment found that the upregulation of MYO6 protein expression was accompanied by the activation of the cGAS-STING pathway, including cGAS, phosphorylated- STING (p-STING)/STING, phosphorylated-TBK1 (p-TBK1)/TBK1, and phosphorylated-IRF3 (p-IRF3)/IRF3, together with increased IL-6 and iNOS expressions in peripheral and midbrain CD4+ T cells from PD mice. Strikingly, deletion of MYO6 and TBK1 in CD4+ T cells attenuated neuroinflammation and DA neuronal death. MYO6 was a novel upstream regulator of TBK1. Here, we determined that the MYO6-cGAS-STING-TBK1 cascade of signaling was involved in the progression of PD. MYO6 may be a potentially CD4+ T cell-associated target for the treatment of PD.",

Delphinidin, an anthocyanidin with reported protective effects, represents a promising candidate, but its direct molecular target and mechanism of action are unclear. The molecular target of delphinidin was identified using Activity-Based Protein Profiling (ABPP), DARTS-MS, SPR, and CETSA. Its functional effects were investigated in 661 W photoreceptor cells and in a light-induced retinal damage model in Sprague-Dawley rats. Protein carbonylation was assessed via an alkynylaniline probe, and Voltage-Dependent Anion Channel 1 (VDAC1) oligomerization was examined by chemical crosslinking. Mitochondrial function, cGAS-STING pathway activation, and ferroptosis markers were evaluated to delineate the underlying mechanism. VDAC1 was identified as a direct target of delphinidin. Light exposure induced VDAC1 carbonylation and oligomerization, leading to mitochondrial dysfunction characterized by cytochrome c release and mitochondrial DNA (mtDNA) leakage into the cytosol. Cytosolic mtDNA activated cGAS-STING pathway, which in turn promoted loss of the ferroptosis suppressor GPX4 and triggered ferroptosis. Delphinidin interrupted this cascade by binding to VDAC1 and inhibiting its carbonylation and oligomerization, thus limiting mtDNA leakage, attenuating cGAS-STING activation, preserving GPX4 abundance, and inhibiting ferroptosis. In vivo, delphinidin intervention conferred significant protective effects, as evidenced by preservation of retinal histoarchitecture and reduced oxidative damage and ferroptosis, CONCLUSION: This study identifies a novel mechanistic axis in RPD linking VDAC1 dysregulation to mtDNA-driven innate immune activation and ferroptosis. It further establishes delphinidin as a direct VDAC1 targeting compound and highlights its therapeutic potential for the prevention of RPD.",

Epidemiological and clinical evidence suggests that lamivudine, a nucleoside reverse transcriptase inhibitor, is associated with a reduced risk of Alzheimer's disease and shows potential in alleviating neuroinflammation. This study therefore aims to employ AD mouse models to further investigate the molecular mechanisms by which lamivudine ameliorates AD-related phenotypes. In this study, we showed that lamivudine administration inhibited cGAS-STING activation and attenuated mitochondrial damage in the 5\u202f\u00d7FAD mouse model, as supported by improved mitochondrial morphology and enhanced mitophagy. These changes were associated with improved spatial memory, alongside reduced neuronal apoptosis and synaptic loss.

HSPA8 is a constitutively expressed molecular chaperone involved in cellular signaling and immune-inflammatory regulation, but its role in EAE-associated neuroinflammation remains unclear. In this study, we found that HSPA8 was significantly upregulated in the spinal cord tissues of EAE mice and positively correlated with disease severity. Immunofluorescence co-staining showed that HSPA8 upregulation was more prominently associated with Iba1-positive microglia/macrophage-enriched regions than with GFAP- or NeuN-positive regions. Intrathecal knockdown of HSPA8 attenuated EAE progression, reduced inflammatory responses, and alleviated demyelination and axonal injury. In vitro, HSPA8 knockdown reduced NLRP3 inflammasome-mediated IL-1\u03b2/IL-18 release, caspase-1 activation, GSDMD-N formation, and pyroptosis in THP-1 cells, bone marrow-derived macrophages, and BV2 microglia, and these effects were partially restored by siRNA-resistant HSPA8 rescue. Mechanistically, HSPA8 knockdown was associated with impaired NF-\u03baB-dependent priming, as reflected by reduced p65 phosphorylation, nuclear translocation, NF-\u03baB transcriptional activity, and pro-IL-1\u03b2 expression. HSPA8 is also associated with ASC, and HSPA8 knockdown impaired NLRP3-ASC interaction, ASC oligomerization, and ASC speck formation during inflammasome assembly. These findings suggest that HSPA8 is functionally associated with NLRP3 inflammasome activation through both NF-\u03baB\u2011dependent priming and ASC\u2011associated assembly, thereby contributing to neuroinflammation in EAE. HSPA8 may represent a potential therapeutic target for MS-related and other inflammasome-driven neuroinflammatory disorders.",

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

"42346242": "ID: 42346242\nTitle: Radiobiotherapy in Osteosarcoma: A State-Based Educational Framework for Strategy Selection and Trial Design.\nAbstract: Background: Osteosarcoma remains a biologically complex and clinically challenging malignancy, with survival gains plateauing despite decades of multimodal therapy incorporating surgery and cytotoxic chemotherapy. Unlike cancers in which mutation-centric precision oncology has yielded transformative advances, osteosarcoma is characterized by profound structural variation, copy number alteration dominance, and dynamic clonal evolution, limiting the effectiveness of single-target approaches. These realities motivate alternative strategy-level frameworks that better align treatment selection with evolving disease behavior. Methods: This narrative educational review synthesizes contemporary evidence from osteosarcoma biology, radiobiology, and translational oncology to propose a state-based framework for integrating radiotherapy-particularly stereotactic body radiotherapy (SBRT/SABR) and spatially fractionated radiotherapy (SFRT)-into osteosarcoma management and clinical trial design. Rather than relying solely on static anatomic stage, this framework emphasizes clinically actionable, time-varying state variables, including disease burden patterns (localized, oligometastatic, polymetastatic), tempo of progression, prior systemic response, and feasibility of complete local control. Results: Within this context, radiotherapy is presented not only as a local control modality but also as a hypothesis-generating biologic intervention, capable of perturbing tumor vasculature, inflammatory signaling, innate DNA-sensing pathways, and immune/myeloid programs in a dose-, fractionation-, and spatial-distribution-dependent manner. The review critically examines both the potential opportunities (e.g., local eradication, immune modulation) and limitations (e.g., rarity of abscopal responses, risk of unintended systemic signaling) of radiobiotherapy combinations, emphasizing the need for cautious interpretation and prospective validation. Conclusions: Finally, the article outlines practical implications for state-stratified, biomarker-embedded clinical trials, highlighting endpoints beyond conventional response criteria, including circulating tumor DNA dynamics, immune and myeloid signatures, and long-term patterns of disease progression. Overall, this review frames radiobiotherapy as an educational and investigational paradigm intended to support rational hypothesis generation, multidisciplinary decision-making, and learning-oriented trial designs in osteosarcoma, rather than as definitive clinical guidance.",

This variability complicates efforts to relate lesion pathology to clinical trajectories. In previous work in the Netherlands Brain Bank MS autopsy cohort (NBB-MS), we showed that relative proportions of different lesion types, lesion load, and microglia/macrophage activity score, associate with clinical severity, while also revealing marked inter-individual variability. Here, we extend these observations by examining whether selected donor-specific pathological features relate to genetic background, quantitative lesion type distributions, and clinical disease course, and thereby help contextualize this heterogeneity.Brain tissue from 287 NBB-MS donors was assessed for the presence of the donor-specific pathological features, namely perivascular cuffs, microglial nodules, broad rim lesions (BRLs), and remyelination efficiency. Perivascular cuffs and microglial nodules were more prevalent among carriers of the MS susceptibility allele HLA-DRB1*15:01 (rs3135388). BRLs and perivascular cuffs were enriched in carriers of the MS severity-associated SNP in the DYSF-ZNF638 locus (rs10191329). Perivascular cuffs associated with increased microglia/macrophage activation score and decreased age at death. Microglial nodules in the normal appearing white matter associated with a higher proportion of active lesions. BRLs were linked to increased proportions of active and mixed active/inactive lesions, higher brainstem lesion rate, and a higher age related MS severity score. Poor remyelination efficiency associated with a higher proportion of mixed active/inactive and inactive lesions, and a shorter disease duration.Together, these findings show that specific pathological features of donors relate to genetic risk, lesion type distribution, and clinical outcome. Integrating these donor-specific pathological features alongside lesion classification will enable a more biologically refined interpretation of post-mortem MS tissue study results and will improve understanding of inter-individual heterogeneity in MS.",

(St. John's Wort) is extensively utilized in ethnopharmacology due to its anti-inflammatory and immunomodulatory properties. However, its effects on the interaction between innate immunity and oxidative homeostasis remain incompletely characterized, particularly in alternative invertebrate models. This study aimed to evaluate the effects of H. perforatum extract on oxidative homeostasis and protein metabolism using the Galleria mellonella model, a 3R-compliant and ethically sustainable platform for preliminary immunological and redox-related screening. Methods: Last instar G. mellonella larvae were administered increasing concentrations of H. perforatum extract (0.001-20 mg mL-1) by intrahemocoelic injection. After 24 h, hemolymph samples were analyzed for total protein (TP), total hemocyte count (THC), encapsulation and melanization responses, superoxide dismutase (SOD) activity, catalase (CAT) activity, and malondialdehyde (MDA) levels. The phytochemical profile of the extract was additionally evaluated using GC-MS analysis. Results: Significant group-dependent alterations were observed in TP levels and THC values, with the HP-2 group demonstrating the highest hemocyte counts and enhanced strong encapsulation responses. Higher extract concentrations, particularly HP-4, were associated with increased weak encapsulation profiles, suggesting altered cellular immune organization. Melanization responses became significantly elevated at 24 h following treatment. In contrast, SOD activity, CAT activity, and MDA levels did not differ significantly among groups, indicating preservation of oxidative homeostasis under the tested conditions. Conclusions: H. perforatum extract induced dose-dependent modulation of cellular and humoral immune responses in G. mellonella without evidence of detectable oxidative disruption during acute exposure. These findings support the utility of the G. mellonella model for preliminary evaluation of botanical immunomodulators and suggest that H. perforatum may influence immunophysiological pathways independently of overt oxidative toxicity.",

We describe four adults referred to a tertiary endocrinology service for unexplained osteoporosis or low-trauma fractures, in whom systemic mastocytosis (SM) was identified during work-up. All had elevated basal serum tryptase (41.4-87.0 \u00b5g/L), bone-marrow biopsy showing atypical mast cells and the KIT D816V variant; cutaneous lesions were absent in every case. Three patients fulfilled WHO 2022 criteria for ISM. The fourth had coexistent JAK2 V617F-positive post-essential-thrombocythaemia myelofibrosis and was classified as SM with associated haematological neoplasm (SM-AHN); his mast cell clone (tryptase 43.7 \u00b5g/L; KIT D816V VAF 0.391%) behaved indolently and contributed clinically through osteoporosis alone, illustrating that an indolent mast cell component can be overlooked when a chronic myeloid neoplasm dominates the picture. Presentations ranged from an isolated low-energy L5 fracture in a 55-year-old man, to multiple vertebral compression fractures despite denosumab in a 71-year-old woman with primary hyperparathyroidism, to severe wasp-sting anaphylaxis in a 43-year-old man. After multidisciplinary review, all received intravenous zoledronic acid with vitamin D repletion; KIT-targeted therapy is under consideration in selected patients. Although causal inferences cannot be drawn from four retrospectively identified cases, the series illustrates how ISM may be missed in unexplained or treatment-refractory osteoporosis-particularly in younger men, those with prior severe anaphylaxis, and those fracturing on antiresorptive therapy-and supports combining basal serum tryptase with high-sensitivity peripheral-blood KIT D816V testing, in line with the WHO/ICC/AIM-ECNM 2022-2024 criteria. Prospective studies are needed.",

While there is a small component of genetic susceptibility to MS risk, environmental factors, including infectious exposures, are gaining increased recognition as playing a critical role in MS initiation and progression. Viral infections, especially by Epstein-Barr virus (EBV), have emerged as strong candidates and triggers of MS symptoms, through antibody-mediated molecular mimicry and B-cell dysregulation. In contrast, parasitic infections, including helminths and select protozoa, appear to exert neuroprotective effects by skewing immune responses toward regulation and tolerance. In this review, we examine antibody-driven mechanisms by which viral pathogens promote autoimmunity in MS and contrast these with parasite-induced immunoregulatory pathways that suppress pathogenic inflammation. We further discuss diagnostic and therapeutic implications, highlighting how insights from infectious immunology may inform novel strategies for MS treatment.",

Interferon-\u03b2 (IFN-\u03b2) is one of the earliest disease-modifying treatments (DMTs) approved for MS and remains widely used in special populations (pregnant and elderly patients) owing to its favorable safety profile. However, the exact mechanism of action of this drug and reliable biomarkers of treatment response remain unclear. Transcriptomic profiling and data integration approaches offer powerful tools for investigating complex patterns of regulation and molecular mechanisms underlying therapeutic efficacy. In this study, we performed an integrative analysis of openly available transcriptomic datasets to characterize IFN-\u03b2-induced gene expression changes in MS patients. By combining data from large independent cohorts, we identified a 43-gene transcriptional signature consistently associated with IFN-\u03b2 treatment across disease stages, including progressive MS. To explore the relevance of this signature, we cross-referenced the 43-gene signature with publicly available expression quantitative trait loci (eQTL) datasets to determine whether these genes could be influenced by known MS-associated risk variants highlighting Interferon-Induced Transmembrane Protein 3 (IFITM3) as a candidate molecular mediator of MS. This integrative approach provides new insights into IFN-\u03b2-driven immune modulation and supports the development of therapeutic strategies for MS.",
"42353155": "ID: 42353155\nTitle: Early Combined B-Cell Depletion and BTK Inhibition Reduced TLS-like Structures and Relapse in PLP139-151-Induced EAE.\nAbstract: B-cell-depleting therapies have revolutionized multiple sclerosis (MS) treatment, yet relapses persist in some patients-suggesting additional pathogenic drivers beyond peripheral B cells. Tertiary lymphoid structures (TLS) are extensively documented in progressive MS at autopsy, but whether their formation begins during the relapsing-remitting phase and how they evolve during the transition to progression remain undefined. Here, using the relapsing-remitting PLP139-151-induced EAE model, we uncover that TLS-like structures form in the subventricular zone during relapse, once established, persist through remission as niches containing both B cells and persistently activated microglia. Neither B-cell depletion alone nor BTK inhibition alone fully prevents relapse. Strikingly, early combined B-cell depletion and BTK inhibition virtually abolishes TLS-like structure formation and may effectively prevent complete disease relapse in this model. By contrast, late initiation of the same combination fails to resolve existing TLS-like structures or prevent relapse, although it attenuates disease severity. These data indicate that established TLS-like structures may represent treatment-resistant compartments, and that both B cells and microglia may be crucial during early formation for sustaining their disease relapse-driving activity. Our study confirms that TLS-like structures may be a key factor driving the compartmentalization of central nervous system inflammation, points to a potentially narrow therapeutic window for intervention, and proposes that early combined B-cell depletion and BTK inhibition may represent a promising strategy worthy of further investigation.",
"42354813": "ID: 42354813\nTitle: BTNL2 Inhibits Pyroptosis in H37Ra-Infected Macrophages by Maintaining Mitochondrial Homeostasis.\nAbstract: Butyrophilin-like 2 (BTNL2) is an immunomodulatory molecule critically involved in regulating the host immune response to infection with the avirulent Mycobacterium tuberculosis strain H37Ra. However, its functional role in modulating pyroptosis and associated inflammatory responses remains incompletely characterized. Here, we demonstrate that BTNL2 deficiency exacerbates pyroptosis and the inflammatory response in H37Ra-infected murine peritoneal macrophages via two distinct pathways. First, the loss of BTNL2 induces excessive mitochondrial damage, which leads to aberrant release of mitochondrial DNA (mtDNA) and accumulation of mitochondrial reactive oxygen species (mtROS), thereby triggering NLRP3 (NOD-like receptor family pyrin domain containing 3) inflammasome activation and gasdermin D (GSDMD)-mediated pyroptosis. Second, cytosolic mtDNA accumulation hyperactivates the cGAS-STING signaling axis, resulting in transcriptional upregulation of NLRP3 and consequent amplification of pro-inflammatory cytokine production. Collectively, these findings demonstrate that BTNL2 acts as a regulator of mitochondrial homeostasis and innate immune balance during H37Ra infection in primary peritoneal macrophages. The results provide mechanistic insights into BTNL2 function in the context of H37Ra-induced pyroptosis.",

Zhi-Zi-Chi Decoction (ZZCD), a classic Traditional Chinese Medicine (TCM) formula, has been clinically used to alleviate mental disturbances via the TCM principle of \"clearing heat and relieving restlessness.\" Still, its modern neuroprotective mechanisms, especially its links to gut microbiota and central signaling pathways, remain incompletely elucidated. Purpose: This study aimed to systematically investigate the therapeutic effects of ZZCD on chronic restraint stress (CRS)-induced neurodysfunction in mice and clarify its mechanisms from the perspectives of TCM theory, material basis, gut microbiota-metabolite axis, and central signaling pathways. Method: CRS mice were treated with ZZCD or protocatechuic acid. Behavioral tests evaluated depression- and anxiety-like behaviors. UHPLC-Q-TOF/MS identified ZZCD's chemical constituents; 16S rRNA sequencing and untargeted metabolomics analyzed gut microbiota and metabolite changes. Western blot, immunofluorescence, and proteomics examined neuroinflammation, microglial polarization, and signaling pathway activity (PI3K/Akt/mTOR, AMPK). Results: ZZCD reversed CRS-induced depression- and anxiety-like behaviors and suppressed neuroinflammation. Mechanistically, UHPLC-Q-TOF/MS identified 424 ZZCD constituents, with prenol lipids, organooxygen compounds, and flavonoids as the most abundant. ZZCD reversed CRS-induced imbalance in gut microbiota, reducing pro-inflammatory Prevotella and enriching beneficial Lactobacillus, and mediated the enrichment of the prebiotic metabolite PCA in colonic and serum samples, which crossed the blood-brain barrier (BBB) to exert neuroprotection. Additionally, ZZCD and PCA normalized the PI3K/Akt/mTOR pathway and activated AMPK, promoting M2 microglial polarization and restoring synaptic plasticity. Conclusions: ZZCD exerts antidepressant effects by a gut-microbiota-dependent modulation of PCA-PI3K/Akt/mTOR and AMPK dual axes that converts microglia from M1 to M2, providing ethnopharmacological evidence and a mechanistic rationale for its clinical application in major depressive disorder.",

Methods: We constructed a sialic acid-disulfide bond-camptothecin (SA-SS-CPT) nanowire system. Sialic acid was used as a targeting ligand to specifically recognize the overexpressed Siglec-E receptor on TAMs. Upon cellular internalization, the disulfide bond was designed to respond to intracellular glutathione (GSH), enabling controlled drug release. Results: The SA-SS-CPT nanowires significantly improved CPT solubility and enabled targeted delivery to TAMs. Following GSH-responsive cleavage and CPT release, the nanowires induced DNA damage in TAMs, activating the cGAS-STING signaling pathway. This promoted TAM polarization toward the M1 phenotype, enhanced pro-inflammatory and anti-tumor immune responses, and inhibited tumor immune escape. Furthermore, SA-SS-CPT synergistically improved the efficacy of PD-L1 blockade immunotherapy, remodeling the tumor immune microenvironment. Conclusions: The SA-SS-CPT nanoplatform effectively targets TAMs, repolarizes them to an anti-tumor M1 phenotype, and activates the cGAS-STING pathway. It shows strong potential for overcoming tumor immune escape and synergizing with PD-L1 checkpoint blockade to achieve significant tumor clearance.",

Its role has expanded from conventional local tumor eradication to active regulation of the tumor immune microenvironment. In recent years, emerging radiotherapy strategies, including FLASH radiotherapy, boron neutron capture therapy, lattice radiotherapy, spatially fractionated radiation therapy, precision particle therapy, immunomodulatory stereotactic body radiotherapy, and immune-optimized carbon ion therapy, have provided new opportunities to improve tumor control, reduce normal tissue toxicity, and overcome radioresistance. Radiotherapy can induce DNA damage and immunogenic cell death, promote tumor antigen release, enhance dendritic cell maturation and antigen cross-presentation, and increase CD8+ T-cell infiltration and antitumor immunity through the cGAS-STING type I interferon pathway. However, radiotherapy may also trigger immunosuppressive feedback, including the accumulation of myeloid-derived suppressor cells, tumor-associated macrophages, and regulatory T cells, as well as the upregulation of immune checkpoint molecules such as programmed death-ligand 1 (PD-L1). These changes may limit antitumor immune responses and contribute to radioresistance. Combining radiotherapy with immune checkpoint inhibitors can amplify antitumor immunity, but therapeutic efficacy is influenced by dose fractionation, treatment timing, tumor type, and baseline immune status. This mini review summarizes emerging radiotherapy strategies and their regulatory effects on the tumor immune microenvironment, and discusses the mechanistic basis, current challenges, and future directions of radiotherapy combined with immunotherapy.",

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.",

This study presents an integrated multidimensional computer-aided drug design (CADD) approach that utilises machine learning (ML), molecular docking, molecular dynamics (MD) simulations, and ADMET prediction to efficiently prioritize\u00a0new STING expression\u00a0suppressor candidates from natural products. We developed a precise ML-based STING classification model with 90.2% accuracy and a robust STING inhibitor activity regression model demonstrating strong predictive capabilities, as evidenced by an R2 of 0.826, MAE of 0.357, and RMSE of 0.452. Virtual screening across multiple traditional Chinese medicine (TCM) compound libraries (Tao Shu L6810, TCMIO, TCMBank, and HERB) yielded 1,596 compounds with predicted pIC50\u2009\u2265\u20097.00. After a rigorous multistep screening, seven compounds were selected for ADMET evaluation and experimental validation. Notably, two natural compounds, Cassiaside and Plantaginin, showed inhibitory activity on STING protein expression in THP-1-derived macrophages, and MD simulations, along with CETSA experiments, further validated their stable binding to the STING protein.

CSF1R inhibitors are under investigation for various diseases, including cancer, autoimmune/inflammatory diseases, and neurodegenerative disorders. PLX5622 is a highly specific, brain-penetrant, and orally bioavailable CSF1R inhibitor that is being evaluated in a clinical trial for rheumatoid arthritis and considered as an attractive candidate for the treatment of Alzheimer's disease (AD). Drug metabolism significantly influences both the efficacy and safety of therapeutic agents. In particular, bioactivation leading to the formation of reactive metabolites is often implicated in adverse drug effects. In this study, we investigated the metabolism and potential bioactivation of PLX5622 in mouse and human liver microsomes (MLM/HLM) and mice using LC-MS-based metabolomic approaches. Reduced glutathione (GSH) and methoxyamine (NH2OMe) were used to capture reactive intermediates. In total, 12 PLX5622-GSH adducts and five NH2OMe adducts were identified in both HLM and MLM, along with 22 nontrapped metabolites generated from demethylation, hydroxylation, and carbon-carbon cleavage reactions. PLX5622-GSH-related adducts in mice were also assessed and 8 GSH adducts were detected in mouse liver, confirming the occurrence of bioactivation in vivo. Using recombinant human cytochrome P450 (CYP) enzymes and selective chemical inhibitors in liver microsomes, CYP3A was determined to be the primary enzyme responsible for the metabolic activation of PLX5622. These insights into the metabolic pathways of PLX5622 are valuable for further study of its safety and potential drug interactions of CYP3A. Future studies using human primary hepatocytes or physiologically human-relevant models such as liver-on-a-chip systems are warranted to confirm clinical relevance and better predict in vivo outcomes.",
"42364023": "ID: 42364023\nTitle: Neurotherapeutic roles of the protective arm of the renin-angiotensin system: from inflammation to cognitive rescue.\nAbstract: The renin-angiotensin system (RAS), traditionally recognized for its role in regulating blood pressure and fluid homeostasis, is increasingly understood to exert important effects across multiple organ systems, including the central nervous system (CNS). A local brain RAS contributes to neurovascular regulation, inflammation, oxidative stress, synaptic plasticity, and cognitive function. This review critically summarizes the neurotherapeutic relevance of the protective RAS arm, particularly the angiotensin-converting enzyme 2 (ACE2)-angiotensin-(1-7)-Mas receptor axis, the angiotensin II type 2 receptor (AT2R), and the alamandine/Mas-related G protein-coupled receptor D (MrgD) pathway. Experimental evidence suggests that these pathways may counterbalance angiotensin II type 1 receptor signaling by reducing neuroinflammation, oxidative injury, vascular dysfunction, and neuronal loss in models of ischemic stroke, Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The strongest evidence remains preclinical, with most data derived from cell culture and animal models, whereas human evidence is still indirect and largely based on observational or early translational studies of RAS-modifying drugs. Important uncertainties remain regarding blood-brain barrier penetration, receptor-specific signaling, disease-stage dependency, systemic vascular effects, and reproducibility across models. Therefore, protective RAS signaling should be considered a promising but still exploratory therapeutic framework rather than an established treatment strategy for neurological disease. Future work should prioritize selective brain-penetrant agonists, validated biomarkers of central RAS activity, and rigorously designed clinical trials to determine whether modulation of ACE2-angiotensin-(1-7)-Mas, AT2R, or alamandine/MrgD signaling can produce clinically meaningful neuroprotection.",
"42364313": "ID: 42364313\nTitle: Occlusal abnormalities and temporomandibular joint osteoarthritis: A narrative review of cross-scale mechanical-metabolic-immune mechanisms.\nAbstract: To synthesize recent multiscale evidence and propose a unified mechanical-metabolic-immune framework for the role of occlusal abnormalities in temporomandibular joint osteoarthritis (TMJOA) pathogenesis. A narrative literature search was conducted in PubMed/MEDLINE, Scopus, and Web of Science for English-language articles published between January 2011 and April 2026. Search terms combined concepts related to temporomandibular joint osteoarthritis, malocclusion or occlusal abnormalities, mechanotransduction, Piezo1, integrin signaling, mitochondrial dysfunction, cGAS-STING activation, single-cell transcriptomics, macrophages, and sexual dimorphism. Clinical, imaging, animal, cellular, omics-based, and mechanistic studies relevant to TMJOA were narratively synthesized. Occlusal abnormalities may alter mandibular kinematics and joint stress distribution, thereby activating mechanotransduction through Piezo1, integrins, and related developmental feedback loops. Sustained mechanical overload may promote calcium dysregulation, endoplasmic reticulum stress, mitochondrial dysfunction, and activation of the cGAS-STING pathway. These changes can shift cellular metabolism toward increased glycolysis and contribute to a pro-inflammatory microenvironment. Single-cell and lineage-tracing evidence further suggests that sex-related immune regulation, including macrophage ontogeny and Xist-associated inflammatory responses, may contribute to the female predominance of temporomandibular joint disorders, although TMJ-specific validation remains needed. TMJOA progression can be interpreted as a cross-scale process in which abnormal occlusal loading links biomechanical stress, metabolic dysfunction, and immune remodeling. These pathways may represent potential targets for future mechanism-based diagnosis and therapy.",

However, effective suppression of pro-inflammatory macrophage polarization for treating radiation-induced hematopoietic stem cell injury is largely hindered by the inherent physiological barriers of bone marrow-targeted drug delivery. In this study, we develop a STING nanoinhibitor composed of poly(lactic-co-glycolic acid) nanoparticle loaded with a STING inhibitor and surface-coated senescent neutrophil membrane for targeted treatment of ionizing radiation-induced hematopoietic injury. Our STING nanoinhibitor can home to bone marrow via the CXCR4/SDF-1 axis and be phagocytosed by macrophages to shift activated pro-inflammatory M1 macrophages to the anti-inflammatory M2 phenotype through suppressing cGAS-STING signaling, and this STING inhibition can further reduce radiation-induced reactive oxygen species (ROS) accumulation to reduce M2-to-M1 macrophage polarization. In irradiation-treated mouse models, the STING nanoinhibitor preferentially accumulates in bone marrow to alleviate pancytopenia, preserve bone marrow architecture, and accelerate hematopoietic recovery while avoiding significant side effects. This study highlights the targeted modulation of bone marrow macrophages as a promising strategy for promoting hematopoietic cell recovery from radiation-induced injury.",

Given the global rise in metabolic dysfunction, this study investigated whether prediabetes amplifies the neurotoxic impact of chronic chlorpyrifos (CPF) exposure and examined arachidonic acid (AA) as a potential modulator of the associated detrimental phenotype, with emphasis on endocannabinoid system (ECS) perturbation. Male Sprague-Dawley rats were rendered prediabetic and dermally exposed to CPF for 35 days, in the absence or presence of oral AA supplementation (3\u202fmg/kg/day). Chronic CPF exposure induced systemic metabolic dysfunction, cerebrovascular hypoperfusion, adipose inflammation, and marked neuroinflammation accompanied by cognitive and motor impairment, as assessed by behavioral testing, laser speckle imaging, biochemical assays, histopathology, immunohistochemistry, and LC-MS/MS. These effects were exacerbated in prediabetic rats. CPF accumulated preferentially in adipose depots and brain tissue and was associated with elevated IL-1\u03b2 and oxidative stress. Molecularly, CPF disrupted ECS homeostasis, with increased hippocampal 2-arachidonoylglycerol levels, downregulation of CB1 receptors, and upregulation of CB2 receptors, consistent with a stress-induced but functionally impaired endocannabinoid response. AA supplementation significantly mitigated CPF- and prediabetes-induced dysfunctional phenotype, and rebalanced ECS signaling. Collectively, these findings identify early prediabetes as a critical vulnerability state that aggravates OP neurotoxicity and demonstrate that AA exerts broad neuroprotective and metabolic benefits, in part through modulation of endocannabinoid and inflammatory signaling. This work highlights the ECS-adipose-brain axis as a pharmacologically relevant interface linking environmental toxicant exposure to metabolic and neurocognitive decline.",
"42365629": "ID: 42365629\nTitle: Current perspectives on the pathogenesis of multiple sclerosis: A minireview.\nAbstract: Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disease of the central nervous system characterized by inflammation, reactive gliosis, and progressive neuroaxonal damage resulting in heterogeneous clinical and histopathological manifestations. As MS often leads to disability at a young age, it represents a substantial socio-economic burden in developed countries. The etiopathogenesis of MS is multifactorial and incompletely understood, involving genetic, immunologic, and environmental factors. Recent research highlights immune responses to Epstein-Barr virus, blood-brain barrier disruption, microbiome-gut-brain axis alterations, oxidative damage, and mitochondrial dysfunction. Studying patients with newly diagnosed MS without significant comorbidities provides insight into early disease mechanisms before disability development or long-term treatment effects. This mini-review focuses on early vascular and metabolic alterations that may contribute to MS, including lipoprotein subfractions as markers of incipient atherosclerosis, endothelial dysfunction as an initiating vascular event, and autonomic nervous system imbalance during disease progression. It also addresses insulin sensitivity as a key metabolic factor alongside chronic inflammation and oxidative damage as interconnected mechanisms driving tissue injury. Metabolic changes reflecting neuronal impairment, mitochondrial dysfunction, and astroglial activation are detectable in both lesional and normal-appearing white matter in early stages. Reduced antioxidant capacity supports a role of oxidative damage in MS pathogenesis. Accelerated vascular aging, independent of traditional cardiovascular risk factors, may progress from endothelial dysfunction to structural atherosclerotic changes. Subtle alterations in lipoprotein profiles further suggest an increased risk of atherosclerosis, potentially influenced by inflammatory activity and oxidative damage, with possible sex-specific differences. Autonomic dysfunction appears to develop secondary to disease progression rather than as a primary driver of pathogenesis.",
"42365956": "ID: 42365956\nTitle: Dive Injury and Jellyfish Sting Case Study.\nAbstract: Wildlife exposure is a risk that trained divers are fully aware of. Examples of hazardous wildlife that divers may encounter include, but are not limited to, sharks, coral, sponges, eels, and jellyfish. Encountering wildlife can lead to a diver panicking or being forced to surface rapidly or in an uncontrolled manner due to panic or avoidance of the hazard. This may increase the risk of decompression illness (DCI), mainly pulmonary overinflation syndrome (POIS). Injuries caused by hazardous aquatic wildlife can also be distracting, leading dive supervisors and/or medical personnel to overlook unrelated injuries, such as DCI. If this occurs, the affected diver may suffer a grave outcome that could otherwise have been prevented. A 23-year-old Army Engineer diver developed sharp chest pain shortly after a 70-foot SCUBA dive complicated by suspected Portuguese man-of-war envenomation. He had painful tentacle contact on both hands/arms and neck, treated immediately with oxygen, vinegar, and seawater irrigation. In the ED, he was stable with normal oxygenation, ECG, labs, venous blood gas, and troponin. His chest pain resolved within 90 minutes, and skin findings improved with topical steroids and antihistamine therapy. He was diagnosed with jellyfish envenomation and atypical chest pain rather than a diving-related injury. At one-month follow-up, he was asymptomatic with normal chest radiographs and was cleared to return to diving. It is of the utmost importance to be aware of all possible injuries or maladies that could have occurred to a diver, and for medical personnel to avoid becoming hyper-focused on a single injury, such as wildlife exposure or trauma.",

Aging modifies MS pathobiology, with the dominant disease mechanisms moving from focal, relapse-driven inflammation to chronic, compartmentalized neuroinflammation and neurodegeneration. In this narrative review, we summarize current knowledge on the relationship between brain aging and MS, integrating clinical, radiological, pathological and therapeutic evidence. We first discuss mechanisms of immunosenescence and \"inflammaging\", including changes in adaptive and innate immunity, gut microbiota dysbiosis, mitochondrial dysfunction and blood-brain barrier dysfunction, and how these processes favor microglial activation, slowly expanding lesions, smouldering MS and progression independent of relapse activity. We then examine the impact of age on disability trajectories, cognitive decline and comorbidities, and the role of vascular and neurodegenerative mechanisms. The review also addresses age-related changes in safety and efficacy of disease-modifying therapies (DMT), with a focus on high-efficacy DMT, de-escalation and discontinuation strategies, and the management of infections, malignancies and polypharmacy in older pwMS. Finally, we describe new approaches relevant to this population, including Bruton's tyrosine kinase inhibitors, neuroprotective and remyelinating agents, advanced cellular therapies and lifestyle-based interventions. We conclude by outlining practical implications for personalized treatment decisions in older pwMS and open questions that future clinical trials and biomarker studies must address.",

However, this immune effect lacks specificity, and prolonged stimulation by live bacterial colonization may lead to immune tolerance. Sonodynamic therapy triggers cellular death and lysis, fully activating the antigen presentation process by providing heterologous DNA and tumor antigen in situ. Herein, to enhance the immunological effect facilitated by ultrasonic treatment, a manganese-containing porphyrin-based metal-organic framework (Mn-MOF) was modified as an acoustic sensitizer on the surface of Escherichia coli to form bacterial sonosensitizer hybrid systems (HA@Mn-MOF@E). Importantly, HA@Mn-MOF@E was able to target and colonize 4T1 tumors due to the anoxic tendency of anaerobes. The ultrasound-induced bacterial and tumor cell death and released manganese could activate macrophages and dendritic cells (DCs) through the activation of the cGAS-STING pathway, which increased the proportion of CD3+ T cells and M1/M2 ratio within the tumor, as well as CD8+ effector T cells and CD86+ DCs in lymph nodes. By sono-sensitized immunotherapy, HA@Mn-MOF@E was demonstrated to inhibit orthotopic 4T1 tumor progression and induce tumor necrosis effectively. Such a designed bacterial sonosensitizer hybrid system offered the possibility of using sonodynamic assistance to sensitize live microorganisms-induced immunotherapy, with thorough activation of the antigen presentation in the tumor.",

Recent findings implicate chemokine-like factor 1 (CKLF1) as a key contributor to the impaired clearance of dying neurons. Here, we established an integrated high-throughput screening strategy combining biolayer interferometry (BLI), liquid chromatography-tandem mass spectrometry (LC-MS/MS), and NanoBRET technologies to identify CKLF1 inhibitors among Panax notoginseng saponins (PNS). Of note, ginsenoside Rg1 (GRg1) exhibits the highest affinity for CKLF1 and the most potent inhibitory efficacy against the CKLF1-CCR4 interaction, effectively suppressing CKLF1-C27 peptide-induced calcium influx and cytokine production. In experimental AIS models, GRg1 confers neuroprotective properties by mitigating ischemic brain damage and promoting neuronal functional recovery. Mechanistically, GRg1 binds to CKLF1 and modulates the mTORC1/TFEB pathway, enhancing lysosomal function and thereby facilitating the clearance of dead/dying neurons. This study presents an efficient approach for the discovery of natural CKLF1 inhibitors and highlights GRg1 as a promising therapeutic candidate for enhancing the clearance of dead/dying neurons in AIS.",

Various underlying mechanisms are likely to contribute, augmented by comorbidities (such as vascular risk) and ageing. In the phase 2b MS-STAT trial, simvastatin (80\u2005mg) (Sandoz Ltd, Camberley, UK) reduced the mean annualised whole brain atrophy rate by 43% compared to placebo in patients with secondary progressive multiple sclerosis (p\u2005=\u20050.003). We now report the phase 3, MS-STAT2 trial, with confirmed progression of disability as the primary outcome. A multicentre, phase 3, randomised, double-blind, placebo-controlled clinical trial was conducted at 31 UK neuroscience centres and district general hospitals. Secondary progressive multiple sclerosis participants aged 18-65 years were randomised 1\u2005:\u20051 to oral simvastatin (80\u2005mg), or matched placebo, based on a minimisation algorithm that incorporated the following factors: sex (male/female); age (< or \u2265\u200545 years); Expanded Disability Status Scale baseline score (\u2264\u20055.5 or \u2265\u20056); whether participants were taking newly licensed (2017 onward) disease-modifying treatments for secondary progressive multiple sclerosis; and trial site. An independent and secure online randomisation service was used. All participants, site investigators and the trial co-ordinating team were blinded to treatment allocation. The Expanded Disability Status Scale was measured every 6 months and was compared to baseline scores, with remote data collection used when enforced by the COVID-19 pandemic. The primary outcome was time to Expanded Disability Status Scale-confirmed disability progression. Progression of disability was defined as an increase of at least one point on the Expanded Disability Status Scale if the baseline score was <\u20056, or an increase of 0.5 point if the baseline score was \u2265\u20056. The initial disability progression event was finalised as confirmed if the increase in Expanded Disability Status Scale score persisted at the next assessments \u2265\u20056 months later. Follow-up was for 36 months, or 54 months, for those without confirmed disability progression at 36 months who agreed to enter an optional blinded extension. An intention-to-treat analysis was carried out. The study was conducted between 10 May 2018 and 26 July 2024. There were 964 participants randomised, with 482 in the placebo group and 482 in the simvastatin group. 173 (35.9%) participants in the placebo group and 192 (39.8%) participants in the simvastatin group experienced Expanded Disability Status Scale-confirmed disability progression (adjusted hazard ratio =\u20051.13, 95% confidence interval 0.91 to 1.39, p\u2005=\u20050.263). No material differences in the secondary outcomes were observed. No major safety issues were seen. The MS-STAT2 trial did not demonstrate a treatment effect of simvastatin in slowing disability progression in participants with secondary progressive multiple sclerosis. Despite the favourable outcomes of the previous phase 2b trial, simvastatin use in secondary progressive multiple sclerosis should be confined to existing vascular indications. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 15/57/143. Multiple sclerosis is a lifelong condition that affects the brain and spinal cord. Many people with multiple sclerosis start with a type called relapsing-remitting multiple sclerosis, which can later become secondary progressive multiple sclerosis. Secondary progressive multiple sclerosis causes steady worsening of disability over time, and currently, there are very few treatment options for people without signs of active inflammation. Simvastatin is a cholesterol-lowering drug (a statin) that is widely used for heart disease. Earlier research (the Simvastatin in Secondary Progressive Multiple Sclerosis phase 2 trial) suggested that high-dose simvastatin might slow brain shrinkage and disability in people with secondary progressive multiple sclerosis. To test this further, researchers ran a large phase 3 clinical trial called Simvastatin in Secondary Progressive Multiple Sclerosis (phase 3 trial), involving 964 participants across the United Kingdom. Half were given simvastatin and half a placebo, and they were followed up while continuing to take these for 3 years. For participants whose disability was stable at 3 years, they could continue in the trial on the same medication for up to 4.5 years if they were happy to do so. The main aim was to see if simvastatin could slow down worsening disability, which was measured using a scale called Expanded Disability Status Scale. The Expanded Disability Status Scale data were mainly collected at face-to-face appointments, but some assessments were conducted by telephone when enforced by the COVID-19 pandemic. The results showed no significant difference between the simvastatin and placebo groups. Simvastatin did not delay disability progression. The trial also looked at other outcomes such as walking speed, hand function, memory and quality of life. Again, there were no meaningful differences. Importantly, simvastatin was generally safe, and side effects were rare. The trial also found that people with higher disability levels faced higher personal and financial costs, and many relied on unpaid care from family or friends. Overall, the Simvastatin in Secondary Progressive Multiple Sclerosis phase 3 trial provides clear evidence that simvastatin does not have a therapeutic effect in slowing disability progression in people with secondary progressive multiple sclerosis. It also offers valuable insights for future research into progressive multiple sclerosis and highlights the need for new treatments that target the disease\u2019s underlying causes.",

Adipose tissue functions as a critical endocrine organ, playing a central role in maintaining glucose homeostasis during fasting, feeding, and stress responses. In this study, we demonstrated that prolonged chronic hyperinsulinemic stress increases the burden of senescent adipocytes, accompanied by activation of the cGAS-STING signalling pathway. Chronic hyperinsulinemia-induced insulin-resistant 3T3-L1 and human mesenchymal stem cell-derived adipocytes exhibited elevated senescence-associated phenotypes, mitochondrial dysfunction and impaired cellular energetics. Notably, we found that mitochondrial DNA leakage triggered the cGAS-STING pathway in insulin-resistant adipocytes and mouse models. Temporal analysis revealed that mitochondrial dysfunction was detectable at earlier stages of chronic insulin exposure, preceding activation of the cGAS-STING pathway and senescence-associated markers, supporting a progressive model of cellular dysfunction. This phenomenon was also observed in adipose depots of individuals with Type 2 diabetes, underscoring the translational relevance of our findings. Targeting cGAS or STING, either pharmacologically or through genetic silencing, significantly reduced inflammatory and senescence-related features in hyperinsulinemia-induced insulin-resistant 3T3-L1 adipocytes. Furthermore, attenuation of senescence treatment with the combination of Dasatinib and Quercetin alleviated mitochondrial stress and associated adipose dysfunction. Collectively, our findings support a model in which prolonged hyperinsulinemic stress induces early mitochondrial dysfunction, followed by activation of cGAS-STING signalling and the subsequent emergence of adipocyte senescence-associated phenotypes, contributing to adipose tissue dysfunction in insulin resistance and Type 2 Diabetes.",
"42372812": "ID: 42372812\nTitle: Qufeng xuanbi formula attenuates HDM-induced allergic asthma by targeting the STING/HIF-1\u03b1/glycolysis axis.\nAbstract: Qufeng Xuanbi Formula (QFXBF), a traditional Chinese medicine prescription used for asthma-like respiratory disorders, has shown anti-asthmatic activity. However, whether it attenuates allergic airway remodeling through innate immune-metabolic regulation remains unknown. This study aimed to determine whether QFXBF alleviates house dust mite (HDM)-induced allergic airway inflammation and remodeling through targeting the STING/HIF-1\u03b1/glycolysis axis, and to evaluate the specific inhibitory potential of its constituent tectorigenin on STING-mediated immunometabolic signaling. An HDM-induced allergic asthma model was established in male C57BL/6 mice by intranasal sensitization and challenge, followed by oral administration of QFXBF at 12.5, 25, and 50\u202fg/kg/day or dexamethasone at 2\u202fmg/kg/day. Airway hyperresponsiveness, lung histopathology, mucus secretion, collagen deposition, \u03b1-SMA expression, inflammatory mediators in BALF and serum, and glycolytic metabolic indices were evaluated. BSMCs were stimulated with IL-4 and LPS, both at 5\u202fng/mL, and treated with QFXBF at 2, 4, and 8\u202fmg/mL. Cell proliferation, migration, glucose consumption, lactate production, RT-qPCR, Western blotting, and immunofluorescence were performed to assess airway smooth muscle activation and metabolic reprogramming. Transcriptomic analysis of lung tissue, STING overexpression, HIF-1\u03b1 pharmacological inhibition, LC-MS/MS-based identification of tectorigenin, molecular docking, and molecular dynamics simulations were further used to investigate the STING/HIF-1\u03b1/glycolysis axis and the potential STING-targeting activity of tectorigenin. QFXBF markedly reduced airway hyperresponsiveness, inflammatory infiltration, and collagen deposition in HDM-challenged mice, accompanied by decreased asthma-related markers in bronchoalveolar lavage fluid and serum. QFXBF also downregulated STING, HIF-1\u03b1, and key glycolytic enzymes at both mRNA and protein levels in lung tissue. In IL-4+LPS-stimulated BSMCs, QFXBF dose-dependently suppressed proliferation and migration, reduced glucose utilization and lactate accumulation, and concurrently inhibited STING/HIF-1\u03b1 and glycolysis-associated factors. Mechanistically, QFXBF attenuated HIF-1\u03b1 activity and glycolytic flux through suppression of STING. Liquid chromatography-based analysis identified tectorigenin as a bioavailable constituent of QFXBF. In STING-overexpressing BSMCs, tectorigenin significantly reduced STING expression, proliferative activity, and lactate metabolism, supporting STING inhibition as a key pharmacological basis of QFXBF. QFXBF can alleviate allergic remodeling by suppressing the STING/HIF-1\u03b1-mediated glycolytic program. Tectorigenin may act as a potential STING inhibitor that disrupts innate immune-metabolic signaling, providing mechanistic support for QFXBF-derived therapeutic strategies in asthma.",
"42373786": "ID: 42373786\nTitle: Innate immune signaling and functions in astrocytes.\nAbstract: Astrocytes, long considered supportive cells of the central nervous system (CNS), have critical roles in innate immunity. This Review explores immune signaling pathways in astrocytes, including pattern recognition through Toll-like receptors, nucleic acid sensors and inflammasomes. These pathways enable the detection of danger signals and initiate protective responses and endogenous innate immune functions. Downstream signaling pathways, including the interferon, NF-\u03baB and STAT3 pathways, mediate astrocyte reactivity and drive cytokine secretion, antiviral responses, phagocytosis and many other immune functions. While these responses are crucial for CNS health, their dysregulation can contribute to chronic inflammation and neurodegeneration in conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis. Additionally, astrocytes exhibit regional heterogeneity in their immune behaviors, which may influence disease trajectories. We highlight unresolved questions regarding the immune functions of astrocytes, their interplay with professional immune cells and their dual protective and pathological roles.",

Despite US Food and Drug Administration approval of numerous algorithms in neuroimaging, neurophysiology, genetics and chatbots, their real-world impact remains limited. This disconnect between research promise and clinical reality represents a gap in understanding how to translate AI algorithms into clinical benefit for patients globally. In this Perspective, we examine the challenges that prevent clinical AI use in neurology moving beyond pilot studies towards meaningful clinical impact. We consider the steps required in the process of translation, including research, validation of AI models, regulatory approval pathways and clinical implementation. We discuss implementation of AI models as stand-alone products versus embedded platforms, and the requirements for sustainable deployment. Beyond traditional clinical decision support tools, we examine paraclinical applications of AI, including chatbots and ambient voice documentation. We recommend expanding capacity for prospective validation and scaling by implementing and validating technologies across multiple sites and countries, which requires infrastructure from long-term partnerships. Neurology must shift from asking whether AI can work to understanding how to use it safely at scale.",

The understanding of the pathogenesis is still limited. Key factors such as neuroinflammation, neurovascular dysfunction, and disruption of cellular energy metabolism have been identified. There are no evidence-based treatments targeting the pathologic mechanisms of cognitive impairment associated with PCS available to date. Thus, treatment is directed towards symptom relief. EGb 761\u00ae, a dry extract from the leaves of Ginkgo biloba has anti-neuroinflammatory properties, improves microcirculation and neuronal mitochondrial function. Clinical efficacy in the treatment of cognitive impairment has been demonstrated. It is therefore reasonable to assume that the extract might be beneficial for use in cognitive impairment associated with PCS. Case series of patients with PCS reported significant improvement in cognitive function within 6\u202fmonths of treatment. The EGb 761\u00ae Post COVID Cognitive Impairment Study (EGb COCOS) aims to establish whether EGb 761\u00ae is an effective treatment for cognitive impairment in PCS. In this prospective, multicentre, randomised, placebo-controlled, triple-blind trial, treatment effects and safety of EGb 761\u00ae in patients with cognitive impairment associated with PCS will be investigated. Eligible patients aged \u226518\u202fyears with a history of probable or confirmed SARS-CoV-2 infection, diagnosis of PCS with cognitive symptoms that have been present for at least 2\u202fmonths, objective cognitive impairment, and mild-to-moderate anxiety or depressive symptoms will be enrolled. Participants (n\u202f=\u202f400 planned) will be randomised to oral, 12-week treatment with EGb 761\u00ae (240\u202fmg) or matching placebo once daily. The effect of EGb 761\u00ae will be assessed on cognitive, neuropsychiatric, neurosensory, and functional outcomes. The analysis will be exploratory in nature, since generally accepted and validated primary endpoints have not been established. For safety, the incidence of adverse events (AEs) and serious AEs will be recorded. The results of this trial will show for the first time whether EGb 761\u00ae is an effective treatment for cognitive impairment in PCS. https://euclinicaltrials.eu/ctis-public/view/2024-517199-39-00?lang=en, Identifier CTIS2024-517199-39-00.",

To track changes in N-acetylaspartate and myo-inositol in relapsing MS (RMS) and primary progressive MS (PPMS) patients treated with ocrelizumab over 2\u2009years. Single-voxel MRS at 3T was acquired at baseline in 10 healthy controls (HCs), and weeks 0, 12, 24, 52, and 96 in MS participants at a single center. Baseline myo-inositol was higher in PPMS than RMS (p\u2009=\u20090.047) and HC (p\u2009=\u20090.001), and correlated with disability across both MS groups (r\u2009=\u20090.57, p\u2009=\u20090.0006). Following treatment with ocrelizumab, both RMS and PPMS demonstrated declines in myo-inositol over time, returning toward HC levels (RMS p\u2009=\u20090.016; PPMS p\u2009=\u20090.004). Conversely, N-acetylaspartate was not different between groups and remained stable over time. Ocrelizumab treatment is associated with declining myo-inositol levels measured by MRS in both RMS and PPMS. Myo-inositol offers a unique biomarker to track resolution of gliosis and reactive microglia with treatment. Furthermore, the relationship between a higher concentration of myo-inositol and greater disability across both MS subtypes at baseline supports the presence of \"smouldering inflammation\" as a disease process across the spectrum of MS.

"42377668": "ID: 42377668\nTitle: Near\u2011Infrared Photobiomodulation in White\u2011Matter Disease: From Microglial States to Measurable Endpoints.\nAbstract: White-matter (WM) injury contributes to disability across multiple sclerosis, traumatic brain injury, Alzheimer's disease and related dementias, and small-vessel disease. We use microglial state programs as an organizing axis for WM injury-to-repair logic, while emphasizing that WM outcomes are multicellular and involve oligodendrocyte-lineage cells, astrocytes, axons/neurons, and vascular factors. Microglia span an injury-repair continuum, from inflammatory programs that increase oxidative stress and debris burden to repair-competent programs that support debris handling, remyelination, and axonal integrity. Near-infrared photobiomodulation (PBM; ~800-1100\u00a0nm) is most consistently associated with modulation of mitochondrial redox/bioenergetic pathways and inflammatory tone. CCO-centered mechanistic framing is best established near ~\u2009800-850\u00a0nm, whereas longer wavelengths (e.g., ~\u20091064-1070\u00a0nm) may involve additional initiating mechanisms with downstream convergence on shared redox/bioenergetic and inflammatory pathways. Across demyelination and spinal cord injury models, appropriately dosed PBM has been reported to reduce inflammatory glial readouts and to associate with improved myelin/axon-related endpoints and functional measures, although mechanistic certainty varies across models. Human evidence remains early but broadly supports safety; a randomized trial in moderate traumatic brain injury reported treatment-related changes in diffusion-MRI WM metrics, while small dementia and chronic-injury studies report heterogeneous cognitive and physiological signals. Given dose dependence and depth-limited transcranial delivery, we synthesize mechanism-informed, dose-aware reporting guidance and WM-anchored outcome frameworks that pair diffusion MRI/DTI with interpretable biomarkers (e.g., NfL, GFAP, sTREM2) and thermally controlled sham designs. We also note potential indirect/systemic contributions that could help reconcile depth-dose constraints with deeper WM effects.",

This study investigated the protective effects of vanillic acid, exercise, and their combination on early-life stress-induced anxiety- and depression-like behaviors and neuronal damage in the maternal separation (MS) rat model. Pups from Wistar albino rats were subjected to a maternal separation protocol, whereas control pups were not. After the MS protocol, rats were randomly divided into four groups: saline, exercise, vanillic acid (VA; 100\u00a0mg/kg, oral), or a combination group. Before decapitation, behavioral tests were conducted, and tissue samples were collected for assessments. Compared with the MS group, vanillic acid reduced corticosterone levels and anxiety- and depression-like behaviors (p\u2009<\u20090.05\u2009-\u20090.001). Compared with the MS group, oxidative damage (malondialdehyde, glutathione, myeloperoxidase), apoptotic parameters (B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax)), neuronal damage, neuroinflammation (TNF-\u03b1, IL-6), and BDNF activity were reversed in all groups (p\u2009<\u20090.01\u2009-\u20090.001). Nuclear factor-\u03baB (NF-\u03baB) was suppressed in the VA and exercise groups compared with the MS group (p\u2009<\u20090.001), whereas no difference was observed in the combined group. These findings suggest that vanillic acid or exercise may offer a promising strategy for mitigating the harmful neurological consequences of early-life psychological stress.",

By single-cell profiling of circulating memory CD8+ T cells from patients with relapsing-remitting MS, healthy volunteers, and neuroinflammatory controls, we identified an MS-associated cytotoxic subset with NK-like features. These cells increase around relapse activity and belong to an oligoclonal reservoir. In an independent cohort sampled at the first clinical event, an elevated frequency of NK-like CD8+ T cells predicted an aggressive MS course two years later and was associated with a migratory/inflammatory program. Bulk and single-cell RNA-seq confirmed the NK-like transcriptional signature, and functional assays demonstrated TCR-independent cytotoxicity. Immunostaining and spatial transcriptomics revealed enrichment of these cells in MS lesions and a spatial association with macrophages/microglia.

Nucleotide-binding oligomerization domain-like receptors detect pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), activating multiple signaling pathways, including nuclear factor-\u03baB (NF-\u03baB) and mitogen-activated protein kinase (MAPK), and triggering immune responses through inflammasome activation.

"42381886": "ID: 42381886\nTitle: Unlocking the healing power of Berberine: A promising aid for multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a debilitating autoimmune disorder characterized by inflammatory demyelination and progressive neurodegeneration within the central nervous system (CNS). Despite advances in disease-modifying therapies (DMTs), current treatments primarily mitigate relapses and slow disease progression but fall short in comprehensively addressing cumulative disability or neurodegeneration. Berberine (BBR), a naturally occurring isoquinoline alkaloid, has emerged as a promising therapeutic candidate due to its potent immunomodulatory, anti-inflammatory, and neuroprotective properties. In this narrative review, we synthesize the molecular mechanisms underpinning BBR's effects on MS pathology and evaluate preclinical evidence from MS-relevant animal models. Studies in experimental autoimmune encephalomyelitis (EAE) -the primary MS model-and the cuprizone (CPZ) -induced demyelination model demonstrate that BBR (typically 5-300\u202fmg/kg in preclinical protocols) reduces pro-inflammatory cytokines, modulates immune responses, and promotes remyelination-processes critical for counteracting MS-associated neurodegeneration. BBR modulates key signaling pathways, including JAK/STAT and SPHK1/S1P, which are pivotal in attenuating immune-mediated damage and preserving blood-brain barrier (BBB) integrity. Despite its therapeutic potential, challenges such as poor bioavailability and suboptimal pharmacokinetics have spurred investigations into advanced delivery systems. Nanoformulations, particularly BBR-loaded iron oxide nanoparticles (BBR-IONP), have shown superior efficacy in preclinical models by enhancing CNS delivery and improving remyelination outcomes. By highlighting BBR's multifaceted bioactivities, this review underscores its promise as a complementary or alternative approach to address unmet needs in MS management, while acknowledging the critical need for clinical trials to validate these preclinical findings.",

Vaccine efficacy and safety need many field years of study; time constraints due to the pandemic limited the same. A hospital-based study was done in South India among patients who presented with immune-mediated disorders in temporal correlation with COVID-19 vaccination. The study period was 20 months, from March 2020 to November 2021. There were a total of 3,235 patients with neurological issues seen in two tertiary institutions, catering predominantly to patients from lower socio-economic strata in South India. A total of 1,007 (31.12%) patients had\u00a0received COVID-19 vaccination (single dose in 511 [50.7%] and both doses in 496 [49.3%]). The general prevalence of primary demyelinating disease was compared with the background of vaccine-induced demyelination. Chi-square test was utilised for determining the association between neurological sequelae and the type of vaccine administered. Eighteen patients had neurological sequelae, and 16 had a monophasic pattern. Recurrent autoimmunity was seen in two patients who took the Sputnik vaccine. Comparing the prevalence of primary multiple sclerosis (MS) versus vaccine-induced demyelination, there was a statistically significant difference (\u03c7 2 = 572.38; p < .001), which indicates a definite role of vaccination in these patients. The association between neurological manifestations of Covishield and Covaxin showed no statistically significant difference in neurological sequelae (\u03c7 2 = 0.0466; p = .8). The Sputnik vaccine was not considered, as the number was less than five. Anti-myelin oligodendrocyte glycoprotein-associated recurrent optic neuritis was seen in one patient, and tongue atrophy, pyramidal signs, ulcerative colitis and arthritis after 3 months, and C-ANCA positivity were seen following the Sputnik vaccine in one patient. Vaccination is an effective public health intervention. However, in susceptible individuals, it can probably trigger a recurrent and multisystem event by immune dysregulation. The association is an observation-based postulate that needs a longer, larger follow-up. As per this study, it is non-fatal and remits permanently.",

The HLA-DRB1*15:01 allele, the strongest genetic risk factor for multiple sclerosis, has been implicated in shaping pathogenic CD4+ T-cell responses and broader neuroimmune vulnerability, yet how this allele modulates age- and sex-dependent neuroimmune processes within the central nervous system (CNS) remains poorly defined. We investigated the impact of HLA-DRB1*15:01 expression using a humanized mouse model (HLA mice) and wild-type (WT) controls. Male and female mice were analyzed at 6, 9, and 15 months of age, with endocrine stratification in females. Behavioral testing, flow cytometry, immunofluorescence, and multiplex cytokine analyses were used to assess cognitive performance, glial immune-associated changes and oxidative stress, astrocyte-microglia IL-3/IL-3R signaling, endothelial activation, selective immune cell accumulation at CNS borders, tissue organization, and hippocampal cytokine profiles. HLA mice developed age- and sex-dependent cognitive impairment, most pronounced in aged females. HLA-DRB1*15:01 expression promoted progressive microglial immune-associated changes, characterized by increased CD14 and CD68 expression, elevated mitochondrial oxidative stress, altered astrocyte phenotypes, and enhanced IL-3/IL-3R signaling. Hippocampal axonal and myelin organization was disrupted in aged HLA mice and was spatially associated with increased microglial presence. HLA mice also exhibited selective immune remodeling, including increased accumulation of CD4+ T cells and NK1.1+CD3+ natural killer T (NKT) cells, particularly in females, accompanied by endothelial activation marked by elevated ICAM-1 and E-selectin expression. Hippocampal cytokine profiling revealed selective sex-biased alterations, without broad induction of classical inflammatory cytokines. Together, these findings demonstrate that HLA-DRB1*15:01 drives a coordinated, age- and sex-dependent neuroinflammatory program linking behavioral dysfunction, glial immune-associated changes and oxidative stress, selective immune cell recruitment, endothelial activation, tissue remodeling, and targeted cytokine imbalance. This integrated phenotype provides mechanistic insight into how this major MS risk allele confers vulnerability to chronic neuroinflammation during aging, with heightened impact in females, independent of reproductive cycling stage.",

Excessive T-helper cell (CD4+) activation and unregulated cytokine signaling play a key role in its onset and progression. These changes impair communication between peripheral immune cells and CNS resident microglia, astrocytes and oligodendrocytes. This review provides an overview on the contribution of specific subsets of T-helper cells to MS pathology/immunity. Th1 cells release interferon-\u03b3 and lymphotoxin, that stimulate activation of myeloid cells/antigen presentation. Activated by IL-23, the Th17 cells produce IL-17A/F that lowers the blood-brain barrier (BBB) integrity, recruit neutrophils and monocytes, and enhance microglial killing. Activation of CD4+ T cells leads to activation of B cells via T follicular helper cells which couple these processes through the production of IL-21 and CXCR5. This leads to the development of tissue-like aggregates and intrathecal antibody production. T-cell plasticity adds to epitope spreading as well as chronic inflammation, IL-22, IL-9, IL-1\u03b2, IL-6, and TGF-\u03b2 (these are additional mediators involved in the regulation of effector phenotypes). In MS, the regulation of dendritic cell co-stimulation and of glial activation often does not work. This is due to the lack of control of dendritic-cells co-stimulation and the lack of regulation of glial activation by regulatory pathways such as FOXP3+ regulatory T cells and Tr1 cells that secrete IL-10 and TGF-Beta. The review also explores the cytokine network biomarkers, CSF and serum signatures and single-cell immune states, as well as existing and new drugs. These include migration blockade, targeting of S1P-receptors, anti-CD20 therapy, targeting of Th17/GM-CSF and JAK-STAT pathways, low-dose IL-2, approaches of targeting antigens and engineered Tregs. Investigating the areas of stage and compartment-specific CD4+ T-cell circuits can help to advance targeted immunomodulation in progressive MS and neuro-repair.",

While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch.",
"42383355": "ID: 42383355\nTitle: Molecular mechanisms regulating cGAS/STING activation in health and disease.\nAbstract: The cGAS/STING pathway enables cells to sense cytosolic DNA and mount rapid innate immune responses to infection, cellular stress, and tissue damage. While essential for host defense and immune surveillance, inappropriate or sustained activation of this pathway can drive chronic inflammation, autoimmunity, and disease-associated immune dysfunction, which can promote cancer growth. Effective immunity therefore depends on precise regulatory control that restrains cGAS/STING activity under homeostatic conditions while preserving the capacity for swift and robust responses to diverse danger signals. In this Review, we synthesize emerging principles that regulate cGAS/STING signaling across cellular contexts to control signal initiation, amplification, and termination. We discuss how disruption, persistence, or pathological rewiring of these regulatory processes contributes to immune imbalance across health and disease, promoting chronic inflammation, immunosuppression, and tissue pathology, with particular relevance to tumor progression and therapeutic resistance. Finally, we consider how restoring appropriate cGAS/STING regulation, rather than simply enhancing or inhibiting pathway activity, may reestablish immune homeostasis and improve therapeutic outcomes in cancer and other inflammatory diseases, framing the pathway as a dynamic regulatory circuit rather than a simple linear signaling cascade.",

The gut microbiota influences the immune system, metabolism, and nerve cells through the production of neurotransmitters and microbial metabolites that can cross the blood-brain barrier (BBB). The interplay between neuroinflammation and altered oral and gut microbiota is a bidirectional complex path modulated by inflammatory mediators. Recent studies suggest a potential role for Toll-like receptor (TLR) signaling pathways in the induction of neuroinflammation via the oral-gut-brain axis. As neuroinflammation is one of the key elements in the pathophysiology of neurodegenerative and neuropsychiatric disorders, this review was conducted to reflect on the pathophysiological pathways and clinical evidence on the role of TLR and inflammasome signaling pathways via oral-gut-brain axis in neurodegenerative diseases such as cognitive impairment, Alzheimer's disease, Multiple sclerosis, Parkinson's disease, Huntington's disease, and Amyotrophic lateral sclerosis, and psychiatric disorders such as major depressive disorder, anxiety disorders, schizophrenia, bipolar disorders, and Autism spectrum disorders. Because the contributing factors have not been fully understood yet, further studies could help provide novel therapeutic opportunities.",

Microglia are resident immune cells of the central nervous system (CNS) that critically mediate the occurrence and development of CNS diseases, including depression. As the most abundant RNA modification, N6-methyladenosine (m6A) regulates microglial function. However, its role and molecular mechanisms in depression remain unclear. In this study, we found that m6A levels decreased in the microglia of the chronic restraint stress (CRS)-induced depression mouse model. Among m6A modulation factors, Alkbh5, a demethylase, showed a significant increase in expression level. Therefore, we generated microglial-specific conditional Alkbh5 knockout mice and found that Alkbh5 deficiency alleviated CRS-induced depression-like behaviors. Mechanistically, microglial Alkbh5 deficiency inhibited excessive microglial activation, rescued dendritic spine loss, and regulated the vascular changes during CRS. Together, these results highlight the important role of Alkbh5 in regulating microglial function in the CRS-induced depression mouse model, providing a potential therapeutic target for depression.",
"42384430": "ID: 42384430\nTitle: Viruses, Periodontitis, and Systemic Diseases.\nAbstract: Viruses are increasingly recognized as potential modulators of oral biofilm ecology and periodontal inflammation, expanding the traditional bacterial paradigm of periodontitis. Members of the Herpesviridae family, including Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), and herpes simplex virus (HSV), are frequently detected in periodontal tissues and may influence disease activity through latency, reactivation, immune modulation, epithelial barrier disruption, and interactions with bacteria. These processes may contribute to local dysbiosis and sustained periodontal inflammation. The potential systemic relevance of oral viruses is biologically plausible but remains incompletely established. Viral persistence or reactivation in oral niches may contribute to systemic immune activation through hematogenous spread, saliva-mediated dissemination, aspiration, or amplification of inflammatory mediators as IL-1\u03b2, IL-6, and TNF-\u03b1. Accordingly, viruses may act as disease modifiers within the broader relationship between periodontitis and systemic conditions including cardiovascular, metabolic, respiratory, neurogenerative, pregnancy-related, and cancer-associated outcomes. However, the strength of evidence differs across these conditions. Current data support a model in which oral viruses, bacteriophages, bacteria, and fungi form an interconnected biofilm ecosystem that may influence periodontitis progression and systemic inflammatory burden. Nevertheless, most available evidence is observational, associative, or derived from mechanistic experimental models, and definitive proof that viruses are independent etiopathogenic drivers of periodontitis is lacking. Future longitudinal and interventional studies are needed to determine whether viral detection reflects bystander association, disease amplification, or a true pathogenic role, and whether antiviral or phage-based strategies offer clinical benefit beyond established periodontal therapy.",

The immune system primarily targets myelin, the protective covering of nerve fibers, leading to inflammation and damage, and secondary neurodegeneration is a major cause of long-term disability. Common symptoms include vision problems, sensory disturbances, muscle weakness, balance difficulties, and bladder dysfunction. Important advances in treatment have improved outcomes in patients with relapsing forms of multiple sclerosis, particularly through highly effective immune-modifying therapies such as CD20-targeting monoclonal antibodies. However, treatment options for progressive forms remain limited, which highlights the need for therapies that can prevent progression and promote myelin repair.

To date, the precise molecular mechanisms remain incompletely understood. Herein, we showed that DON triggers neurotoxicity by reprogramming microglial glycolysis via activation of the NQO1/NF-\u03baB pathway. Raffinose (Raf), a natural trisaccharide, effectively attenuated DON-induced neuroinflammation in vivo and in vitro. Mechanistically, Raf upregulated NQO1 transcription by selectively binding to Nrf2 at Val-514 and Cys-368, thereby reinforcing the NQO1-I\u03baB\u03b1 interaction, possibly through NQO1-associated regulatory interfaces. This interaction inhibited NF-\u03baB hyperactivation, suppressed glycolysis, and restored oxidative phosphorylation, thereby attenuating DON-induced pro-inflammatory microglial activation. Furthermore, NQO1 knockdown or Nrf2 knockout weakened the inhibitory effect of Raf on the NF-\u03baB signaling pathway and inflammatory activation state of microglia. In conclusion, our findings revealed that Raf supplementation could efficiently alleviate DON exposure-induced neuroinflammation and neurobehavioral deficits by modulating NQO1/NF-\u03baB-associated metabolic remodeling. These findings suggested that Raf may represent a potential therapeutic strategy against DON-induced neuroinflammation.",

Tunneling nanotubes (TNTs) are dynamic F-actin-based intercellular connections which transfer mitochondria and pathogenic factors. Although TNTs have been implicated in various neuropathological conditions, their precise involvement in CM pathogenesis, particularly in relation to microglial activation, remains undefined. In this study, single-cell RNA-sequencing (scRNA-seq) revealed significant dysregulation of TNT-associated genes and actin cytoskeleton pathway remodeling in microglia of ECM model. In vitro studies demonstrated that Plasmodium-infected red blood cells (pRBCs)-stimulated primary microglia formed extensive F-actin-rich tunneling nanotubes, which mediated the bidirectional transfer for mitochondria and facilitated intercellular trafficking of lysosomal contents and malarial pigment. These TNT-mediated intercellular communication amplified microglial activation, as evidenced by: (i) lipid peroxidation, (ii) mitochondrial dysfunction, and (iii) autophagosome (LC3+) accumulation. This process further amplifies neuroinflammation through TNF\u03b1/IL-6 secretion and expansion of CD45high microglial populations. Pharmacological TNT inhibition restores microglial homeostasis in ECM model. In conclusion, TNTs mediate neuroinflammation in the ECM model by transferring mitochondria and malarial pigment between microglia. Although mitochondrial transfer may transiently support cellular homeostasis, progressive malarial pigment accumulation triggers lipid metabolism dysregulation and amplified neuroinflammation. Inhibiting TNTs formation attenuates microglial hyperactivation, highlighting targeted regulation of TNT-mediated intercellular communication as a potential therapeutic approach for CM-associated neuropathology.",

This study pooled data from 47 pwMS treated with various approved disease-modifying therapies and 18 untreated pwMS with TSPO-PET imaging before and after. Therapeutic response was quantified using [11C]PK11195 distribution volume ratio and percentage of active voxels in seven brain regions. Variables predicting therapeutic response were identified using linear mixed-effect models. Power calculation was used to estimate the required sample size for predictor-enriched cohorts. High baseline TSPO binding in the white matter (HOT-PET) was identified as the best predictor for reduction in glial activation following treatment in 6 of 14 (43%) PET variables. Internal validation confirmed that treated HOT-PET patients showed enhanced therapeutic response compared with non-HOT-PET patients in 9 of 14 (64%) PET variables. The percentage of active voxels in the white matter was the best PET variable at capturing a significant therapeutic effect, with a Cohen's d effect size of -0.779 (95% confidence interval -1.332; -0.207). In this cohort, enrichment for HOT-PET patients markedly reduced the sample size required to show a positive treatment effect. HOT-PET patients are more likely to benefit from neuroinflammation-targeting treatments compared to non-HOT-PET patients. Accordingly, enriching trial cohorts for individuals with greater neuroinflammatory burden could improve statistical power and reduce the required number of participants in trials targeting harmful glial activation in MS.",

Data on their prevalence and kinetics in low- and middle-income countries, including Morocco, remain limited. This study aimed to evaluate these infections at the Children's Hospital in Rabat. We conducted a retrospective descriptive study of pediatric patients who underwent HSCT at the Children's Hospital in Rabat from January 2018 to June 2025. Post-transplant viral monitoring included weekly quantitative PCR for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) until day 100. Targeted PCR for adenovirus, BK virus, HHV-6, and respiratory viruses was performed in symptomatic patients. Out of 33 patients, CMV was the most frequently detected agent, with an incidence of 51,5% (n\u2009=\u200917), of which 30.3% had a viral load\u2009>\u20092.5 log\u2081\u2080 IU/ml. The median time to first reactivation was 3\u2009weeks (IQR: 2-6). The vast majority of episodes occurred in seropositive (R+) recipients, mainly D+/R+. The highest viral loads were observed in patients with CMV viremia temporally associated with pulmonary involvement (2.62 log\u2081\u2080 IU/ml [IQR: 0.00-3.42]) compared to those without pulmonary involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04]; p\u2009=\u20090.007), despite the absence of virological confirmation of CMV-related pulmonary disease. Similarly, patients with gastrointestinal (GI) complications had higher viral loads (3.13 log\u2081\u2080 IU/ml [IQR: 2.23-3.89]) compared with those without GI involvement (0.00 log\u2081\u2080 IU/ml [IQR: 0.00-2.04], p\u2009=\u20090.002). Concerning EBV, viral loads showed transient reactivations, fluctuating between quantifiable and undetectable, mainly between the 1st and 7th week post-transplant. Infections were more frequent in recipients who were initially seronegative (D+/R-) included 8 of 13 patients (61.5%), No cases of post-transplant lymphoproliferative disease were reported. BK virus showed an early peak of infection between the 1st and 4th week, strongly associated with the occurrence of hemorrhagic cystitis, highlighting its significant clinical impact during this period. This study highlights the particularly early kinetics of CMV, BK virus, and EBV in our pediatric patients after HSCT, with CMV appearing around week 3, transient EBV reactivations in initially seronegative patients, and an early BK virus peak linked to hemorrhagic cystitis.",

While several individual mechanisms of reactivation have been well characterized, there are potentially other unresolved vulnerabilities that drive HSV-1 reactivation. Traumatic brain injury (TBI) has emerged as a potential trigger of HSV-1 reactivation and represents a complex and clinically relevant perturbation that disrupts neuronal homeostasis, immune surveillance, and inflammatory signaling, processes that are also central to HSV-1 latency and reactivation. However, the mechanisms linking TBI to HSV-1 reactivation remain poorly understood.In this review, we examine whether known mechanisms of TBI-induced cellular stress overlap with pathways implicated in HSV-1 latency and reactivation. We synthesize shared mechanisms, including stress signaling, neuroinflammation, and immune dysregulation during TBI that may create conditions permissive for HSV-1 reactivation in the injured brain. This integrated perspective reframes TBI as a context in which established drivers of HSV-1 reactivation converge and may increase reactivation susceptibility.We propose that HSV-1 reactivation is an emergent property of dysregulated neural systems and that TBI may engage many of these processes. In this framework, viral reactivation is inseparable from the broader neuronal and systemic context in which it occurs. This perspective highlights the importance of integrating neural state, injury, and immune dynamics into models of HSV-1 latency and reactivation. Advancing this multidimensional view will be critical for developing therapeutic strategies that not only suppress viral reactivation but also address neuroinflammation following brain injury.",

Disease outcome in TBM depends critically on early diagnosis and timely initiation of treatment. However, the non-specific clinical presentation of TBM poses a major diagnostic challenge, as no single test can reliably establish a definitive diagnosis. The recommended diagnostic approach, GeneXpert MTB/RIF ultra, combined with mycobacterial culture of cerebrospinal fluid (CSF), remains limited by suboptimal sensitivity and restricted availability in many resource-constrained settings. These limitations underscore the urgent need for novel biomarkers that reflect TBM-specific pathophysiology and enable a single rapid, reliable, and accessible diagnosis. This perspective paper draws on insights from LC-MS-based CSF metabolomic profiling to highlight metabolic alterations in TBM. Key metabolic pathways-fatty acid \u03b2-oxidation reflected by altered acylcarnitine profiles, amino acid perturbations, and the tryptophan-kynurenine pathway-are discussed in relation to cellular energy disruption and neuroinflammation. Based on these alterations, free carnitine and quinolinic acid emerge as priority candidates for further investigation. Free carnitine reflects TBM-associated energy dysregulation, while quinolinic acid appears to mirror the severity of neuroinflammation. Future studies should focus on validating these metabolites in independent cohorts and on assessing their translational potential in more readily accessible biofluids, with the ultimate goal of enabling simplified, widely implemented diagnostic assays.",

We performed an integrated multiomic characterization of small extracellular vesicles (sEVs) released from spontaneous lymphoblastoid cell lines (SLCLs) derived from healthy donors and patients with MS, transformed ex vivo by endogenous wild-type EBV. Proteomics identified over 6,000 shared proteins enriched in nucleic acid-binding and chromatin-associated factors. EV-associated DNA resolved into two structurally distinct compartments: DNase-sensitive, high-molecular weight DNA associated with the vesicle corona and DNase-resistant, nucleosome-sized (\u223c130-150 bp) DNA. Both compartments were overwhelmingly host-derived and broadly genomically distributed, whereas EBV DNA was minimal. In contrast, viral RNA cargo was dominated by the EBV noncoding RNA EBER1, which was strikingly enriched across all lines and confirmed within individual vesicles by ddPCR and super-resolution microscopy. EBER1 has previously been detected in MS brain tissue, yet its route to the CNS has remained unexplained. Our findings identify sEVs as a plausible vehicle for disseminating this immunostimulatory viral ncRNA beyond sites of latency, pointing to EV-mediated export of EBER1 as a candidate mechanism linking peripheral EBV infection to distal tissue signaling in MS and beyond.",

This study analyses the clinical presentation, diagnostic pathways, therapeutic strategies and outcomes of PTLD in renal and pancreatic transplant recipients at the Manchester Centre for Transplantation. A retrospective cohort study was carried out on a cohort of 73 patients diagnosed with PTLD between 2002 and 2025 following renal, simultaneous pancreas-kidney (SPK) or pancreas-only transplantation. Data were collected from electronic medical records and analysed descriptively. Clinical presentations were categorised into organ system involvement. Time from presentation to diagnosis and survival outcomes were assessed. The median time from transplant to PTLD diagnosis was 132 months, with 56% of cases diagnosed more than 10 years post-transplant. Monomorphic PTLD, in particular diffuse large B-cell lymphoma (DLBCL), was the most common subtype. EBV-positivity was seen in all early cases and in 57% overall. Abdominal and B symptoms were the most frequent presentations. Bleeding and/or anaemia were significantly associated with diagnostic delay (p\u2009=\u20090.045), and delays over one month were associated with reduced survival (p\u2009=\u20090.061). Complete or partial remission was achieved in 75% of patients. The 5-year overall survival rate was 68% while 1-year survival was 83% and death-censored graft survival was 82%. In our cohort, PTLD in transplant recipients presents with diverse symptoms and can occur several years post-transplant highlighting the need for long-term vigilance. Streamlined referral pathways and increased awareness could reduce diagnostic delays. Establishing a national PTLD registry would benefit future research.",

To define the fate and function of infiltrating monocyte-derived macrophages (MDM) in retinal degeneration, we generated a CCR2-CreER mouse line on the rd10 background to enable precise monocyte-specific tracking and ablation. Infiltrating monocytes rapidly downregulated CCR2 and LY6C upon entering the retina and acquired de novo TMEM119 and P2RY12 expression, together with a ramified, microglia-like morphology. Immunohistochemistry and transcriptomic profiling showed that a subset of these cells was cleared by resident microglia. Microglia-monocyte interactions enhanced M\u00fcller cell C3 production, whereas activated microglia increased CFB and decreased CFH expression, thereby promoting complement alternative pathway activation. Selective ablation of infiltrating monocytes reduced microglial activation and phagocytosis, suppressed M\u00fcller cell C3 expression and complement deposition, lowered proinflammatory cytokine levels, and ultimately ameliorated photoreceptor degeneration. These findings identify infiltrating monocytes as key drivers of immune dysregulation and proinflammation, highlighting them as potential targets for neuroprotective therapy.",

Existing reviews lack an integrated synthesis of viral mechanisms, TME spatial architecture, and therapeutic translation. We conducted a comprehensive literature search across PubMed, Embase, and Web of Science from inception to December 2025, with an update check to May 2026, following PRISMA guidelines. Given the broad scope, a narrative synthesis was adopted rather than a formal systematic review. Two reviewers independently screened 4,235 records, and 182 studies were included. Methodological quality was assessed using Cochrane RoB 2 and Newcastle-Ottawa tools, with detailed risk-of-bias summaries provided in the Supplementary Materials. EBV establishes hierarchical immunosuppression in NPC. Latent proteins LMP1, LMP2A, and EBNA1, together with non-coding RNAs (BART miRNAs, EBERs), constitutively activate NF-\u03baB, PI3K/AKT/mTOR, and JAK/STAT pathways; LMP1 further promotes exosomal secretion and metabolic reprogramming that expands myeloid-derived suppressor cells. Lytic-phase genetic polymorphisms in BALF2, BZLF1, and BRLF1 are associated with differential immune signatures, though these associations remain correlative and lack functional validation. Based on limited spatial profiling studies, the TME can be provisionally conceptualized as five distinct immunosuppressive niches-immune-excluded fibrotic stroma, immunosuppressive interface, tertiary lymphoid structures, vascular niches, and hypoxic tumor cores. Anti-PD-1-based chemo-immunotherapy achieves 20-91% objective response rates and is now the first-line standard for recurrent/metastatic disease, as established by the JUPITER-02 and RATIONALE-309 trials. EBV-directed adoptive cell therapies, therapeutic vaccines, lytic induction, and stromal modulators have shown early promise, although definitive efficacy data are still lacking. Biomarker integration-including plasma EBV DNA, viral genetic variants, spatial omics, and liquid biopsy-offers potential for patient stratification, yet most emerging markers remain investigational. This comprehensive review provides an evidence-based framework linking EBV latent and lytic mechanisms to TME remodeling and precision therapeutics.

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

From a mechanistic standpoint, our previous work explained this genetic association by defining an immunomodulatory function for ataxin-1 in controlling specific genetic programs underlying B cell proliferation, activation, immunoglobulin production, and antigen presentation. Here, we employed a high-resolution multiomics analytical pipeline to further dissect the role of ataxin-1 in distinct B cell subsets upon encephalitogenic stress. By combining single-nuclei RNA-seq and ATAC-seq, along with mass-spectrometry proteomics, we documented that ataxin-1 is significantly enriched in B1 cells, marginal zone B cells, memory B cells, and precursor B cells. Pathway analysis highlighted that ataxin-1 is implicated in RNA splicing and translation processes. Conversely, no major effects were implicated for ataxin-1 in chromatin remodeling in the B cell population. Our findings expand the current knowledge of the cellular functions controlled by ataxin-1 outside of the central nervous system, and further describe a key regulator of B cell biology in health and disease.",

Berberine and metformin independently activate AMPK and may engage Nrf2-mediated antioxidant defenses, yet their combined neuroprotective interaction has not been formally quantified using validated synergy frameworks, nor has its pharmacokinetic basis been verified. Streptozotocin-nicotinamide diabetic rats were allocated to twelve groups (n\u2009=\u200913/group) receiving berberine (50, 100, 150\u00a0mg/kg/day) or metformin (100, 200, 300\u00a0mg/kg/day) monotherapy, fixed-ratio 1:2 combinations, or vehicle controls (including a non-diabetic combination group) orally for six weeks. The novel object recognition (NOR) discrimination index served as the predefined primary endpoint for Chou-Talalay combination index (CI) analysis. Hippocampal mechanistic (n\u2009=\u20096/group) and satellite LC-MS/MS pharmacokinetic (n\u2009=\u20096/group) analyses were performed. Diabetes impaired NOR discrimination index (37.2\u2009\u00b1\u20093.8% vs. 68.4\u2009\u00b1\u20093.2%; p\u2009<\u20090.001). The reference combination (100\u2009+\u2009200\u00a0mg/kg) restored NOR to 67.1\u2009\u00b1\u20093.6% with CI\u2009=\u20090.65 (95% CI: 0.43-0.91), synergism maintained across the full effect range. All six neuroinflammatory endpoints achieved Benjamini-Hochberg-corrected significance (p_adj\u2009=\u20090.006-0.043; Tier 2). Non-diabetic combination animals showed reduced AMPK activation magnitude (1.53 vs. 2.31-fold; P_adj\u2009=\u20090.067; Tier 3, hypothesis-generating). LC-MS/MS verified bioequivalent drug exposure. Berberine-metformin co-treatment is associated with CI-quantified supra-additive recognition memory recovery in diabetic encephalopathy, with neuroinflammatory suppression as the most statistically robust mechanistic correlate. Pharmacokinetic findings are consistent with a pharmacodynamic rather than pharmacokinetic basis. Causal involvement of the AMPK-Nrf2 axis remains correlative pending direct loss-of-function validation.",
"42390760": "ID: 42390760\nTitle: The dual role of mTOR in multiple sclerosis pathophysiology: a systematic review.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disease characterized by demyelination, neuroinflammation, and progressive neurodegeneration. The mechanistic target of rapamycin (mTOR) pathway plays a key role in regulating immune responses, cell metabolism, autophagy, and repair processes. Although the role of mTOR in neurodegeneration has been explored in previous reviews, a systematic assessment of its function in MS across different models is still lacking. This systematic review aimed to examine the role of mTOR signaling in the pathophysiology of MS. Following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, we screened preclinical and clinical studies using two databases and assessed the risk of bias specific to the study types. A total of 189 records were identified, of which 90 met the\u00a0inclusion criteria for qualitative analysis. Studies using in vitro and in vivo (mainly rodent models, both sexes) models of MS, as well as MS patient tissue or data, consistently demonstrated that mTOR is involved in the MS-related processes neuroinflammation, myelination, autophagy, gliosis, mitochondrial dysfunction, and oxidative stress. mTOR inhibition reduces pro-inflammatory signaling and may enhance autophagy, offering neuroprotection. In contrast, activation of mTOR promotes remyelination by enhancing oligodendrocyte differentiation and maturation. These remyelinating effects may be masked in inflammatory environments, because activation of mTOR supports immune cell expansion and glial reactivity, inducing inflammation and oxidative stress. Overall, our findings underscore a dual role of mTOR in MS pathology, with important implications for disease stage and timing of intervention. Although mTOR is mechanistically important in MS, its therapeutic modulation is unlikely to be readily clinically translatable without a substantial risk of unintended and context-dependent effects.",

However, the RNA structures regulating the splicing of the critical EBV gene, latent membrane protein 1 (LMP1), remain uncharacterized. To identify these regulatory elements, we applied spliceosome inhibition with RNA probing and sequencing (SIRP-seq) to the BJAB-B1 cell line. By utilizing the spliceosome inhibitor pladienolide B, we enriched pre-mRNA species, enabling the detection of structural features within both the full-length pre-mRNA (LMP1-FL) and an alternatively spliced isoform retaining intron 2 (LMP1-AS). The resulting chemical probing datasets informed the RNA folding algorithms RNAfold and ScanFold to generate the first high-resolution secondary structure models for the LMP1 pre-mRNA, encompassing both exonic and intronic regions. Our results identify 11 novel, thermodynamically stable RNA structures, with several key elements positioned near splice junctions. Notably, three structures (Structures 8, 9, and 10) were identified near the 3' splice site of intron 2, appearing in alternative conformations that may influence splicing accessibility. Furthermore, these structures map to regions containing disease-relevant mutations associated with patient survival in Burkitt lymphoma. This structural framework provides new insights into how LMP1 splicing may be regulated by RNA structure and identifies potential novel therapeutic targets for mitigating EBV-associated diseases.",
"42391599": "ID: 42391599\nTitle: Factors Associated With Disability Improvement and Worsening Independent of Attacks in Patients With AQP4-IgG+ NMOSD and MOGAD: A Multicenter Cohort Study.\nAbstract: Disability trajectories in aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorder (AQP4-IgG+ NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are primarily driven by attack-related damage. Confirmed disability worsening (CDW) independent of attacks has been described but occurs infrequently in AQP4-IgG+ NMOSD and MOGAD. Confirmed disability improvement (CDI) has not been evaluated in large cohorts. We determined the frequency of CDI and CDW independent of attacks and identified clinical factors associated with these outcomes in AQP4-IgG+ NMOSD and MOGAD. This retrospective, multicenter cohort study analyzed data from the German Neuromyelitis Optica Study Group (NEMOS) registry. Adult patients with AQP4-IgG+ NMOSD or MOGAD and longitudinal Expanded Disability Status Scale (EDSS) assessments were included. EDSS episodes were defined as periods with \u22653 EDSS assessments without attacks, obtained \u226590 days after attack. CDW and CDI were defined as sustained EDSS increase or decrease (\u22651.5 for baseline EDSS 0; \u22651.0 for EDSS 1.0-5.5; \u22650.5 for EDSS \u22656.0) confirmed after at least 6 months. The primary outcomes were annualized CDI and CDW rates. Risk factors were assessed using multivariable Anderson-Gill regression models. A total of 338 EDSS episodes of 307 patients (n: 202/105, median age at EDSS change: 56/41 years, 88/49% female, both p < 0.001; AQP4-IgG+ NMOSD/MOGAD) were included. Adjusted annualized CDI and CDW rates did not differ between AQP4-IgG+ NMOSD (CDI: 0.083, 95% CI 0.029-0.233; CDW: 0.025, 95% CI 0.007-0.092) and MOGAD (CDI: 0.057, 95% CI 0.012-0.277; CDW: 0.036, 95% CI 0.002-0.513). In AQP4-IgG+ NMOSD, a lower number of prior attacks was associated with higher CDI rates (hazard ratio [HR] 0.89, 95% CI 0.82-0.97). Younger age was associated with increased CDI rates in both AQP4-IgG+ NMOSD and MOGAD (HR 0.96, 95% CI 0.94-0.99, for both). CDI and CDW independent of attacks, although rare, occur in AQP4-IgG+ NMOSD and MOGAD. The association between fewer prior attacks and higher CDI rates in AQP4-IgG+ NMOSD underscores the importance of early attack prevention. Limitations include the retrospective design, and the limited number of CDI and CDW events.",

Growing evidence, however, suggests that chronic infection may exert systemic effects extending to the central nervous system. This review critically examines the potential neurological implications of H.\u00a0pylori infection within the emerging framework of the gut-brain axis. We performed a narrative, hypothesis-generating review of human observational and interventional studies complemented by mechanistic experimental research. The literature was evaluated with particular attention to study design, heterogeneity, and potential confounding in reported associations between H.\u00a0pylori infection and neurological disorders. Across multiple studies, H.\u00a0pylori infection has been linked to a modestly increased prevalence of Parkinson's disease and dementia, although findings remain heterogeneous. In Parkinson's disease, infection may exacerbate motor fluctuations and reduce levodopa bioavailability, with partial clinical improvement reported following eradication in selected patients. Experimental studies further demonstrate that bacterial outer membrane vesicles can access the brain and promote neuroinflammatory and amyloidogenic processes, supporting biological plausibility. By contrast, several epidemiological studies report an inverse association with multiple sclerosis, suggesting potential immunomodulatory effects. Evidence relating H.\u00a0pylori to migraine and mood disorders remains inconsistent. Current data do not support H.\u00a0pylori as a primary cause of neurological disease. Instead, the infection may act as a context-dependent modifier within the complex inflammatory and immunometabolic networks of the gut-brain axis. Clarifying this relationship will require prospective studies integrating microbial strain profiling, biomarker-defined neurological phenotypes, and adequately powered interventional trials.",
"42391876": "ID: 42391876\nTitle: CIRBP mediates hypoxia-induced mitochondrial metabolic reprogramming in microglia to regulate polarization and anxiety-like behavior.\nAbstract: Exposure to high-altitude hypoxia can lead to anxiety-like behaviors, social issues, and other dysfunctions of the central nervous system (CNS), but the molecular mechanisms behind these effects are not fully understood. Microglial M1 polarization and changes in mitochondrial metabolism are crucial in hypoxic brain injury. The cold-inducible RNA-binding protein (CIRBP) is known to regulate mitochondrial balance and inflammatory responses. However, its role in hypoxia-induced microglial metabolic changes, polarization issues, and anxiety-like behaviors is still unclear. This study established an in vivo mouse model of high-altitude hypoxia, an in vitro hypoxic injury model of BV2 microglia, and an in vitro neuronal intervention model with microglia-derived conditioned medium. Integrating in vivo and in vitro experimental designs, we further systematically elucidated the potential molecular mechanisms underlying hypoxic brain injury. Findings indicated that high-altitude hypoxic exposure led to anxiety-like behaviors, social dysfunction, and neuronal and synaptic damage in the hippocampal CA1 region of mice. Hypoxia first triggered mitochondrial metabolic reprogramming in microglia, characterized by inhibition of oxidative phosphorylation, decreased ATP production, and accumulation of reactive oxygen species (ROS) and lactate, which subsequently drove the conversion to the M1 pro-inflammatory phenotype. Inhibition of microglial activation by minocycline significantly reversed hypoxia-induced synaptic damage. At the molecular level, hypoxia downregulated CIRBP expression in microglia. Overexpression of CIRBP in microglia ameliorated mitochondrial metabolic dysfunction and regulated microglial polarization, while knockdown of CIRBP in microglia exacerbated these abnormalities. Targeted overexpression of CIRBP in microglia within the hippocampal CA1 region significantly attenuated hypoxia-induced neuronal damage and behavioral abnormalities. This study elucidates a novel mechanism by which CIRBP in microglia mediates hypoxic brain injury, offering a potential therapeutic target for neuropsychiatric disorders associated with high-altitude hypoxia.",
"42391971": "ID: 42391971\nTitle: Sotagliflozin improves cognitive deficits and attenuates neuroinflammation of Alzheimer's disease.\nAbstract: Effective treatments for Alzheimer's disease (AD) are limited. Due to shared pathological mechanisms between AD and diabetes, antidiabetic drugs like sodium-glucose cotransporter-2 inhibitors (SGLT2is) are potential therapeutic options. Although SGLT2is have shown cognitive benefits in diabetes models, their effects in AD models are not fully established. This study aimed to evaluate the therapeutic effects of sotagliflozin (Sota), an SGLT2i, in both in vivo and in vitro AD models. The network pharmacology analysis was used to predict the potential targets and pathways of Sota. And we selected 6-month-old APP/PS1 transgenic mice to investigate the effects of Sota. Cognitive function was assessed using the Morris water maze test. Immunohistochemistry and immunofluorescence were employed to quantify amyloid-beta (A\u03b2) plaque deposition in the hippocampal or cortex and analyze neuronal loss. Additionally, amyloid \u03b2 oligomers induction and microglial cells were used to evaluate the effects of Sota on the release of pro-inflammatory mediators and to investigate the underlying mechanisms. In vivo, Sota treatment improved cognitive impairments, reduced pro-inflammatory cytokines, inhibited microglial activation, and promoted neuronal survival. In vitro, Sota mitigated A\u00df oligomer-induced toxicity in microglial cells by decreasing reactive oxygen species and pro-inflammatory cytokine release. Mechanistically, Sota treatment was associated with suppression of extracellular signal-regulated kinase (ERK) signaling. Our findings suggest that Sota improved cognitive impairment and attenuates neuroinflammation in AD. Sota may be a promising candidate for the treatment of AD.",
"42392131": "ID: 42392131\nTitle: Interferon-\u03b1 as a precision medicine tool in Sj\u00f6gren's disease: a cohort and experimental medicine study.\nAbstract: Mechanistic heterogeneity is a major obstacle to the development of effective treatment for Sj\u00f6gren's disease, and there is a pressing need to stratify Sj\u00f6gren's disease according to precision medicine principles. Aberrant activation of the type 1 interferon (IFN) pathway represents a leading candidate pathway, but a causal role of elevated IFN\u03b1 in driving Sj\u00f6gren's disease has yet to be established. We aimed to examine the role of IFN\u03b1 in driving a Sj\u00f6gren's disease endotype and relevance to precision medicine principles. We used data from the UK Primary Sj\u00f6gren's Syndrome Registry (UKPSSR), a multicentre observational cohort of participants with Sj\u00f6gren's disease, and UK Biobank, a large population-based cohort which includes people with and without Sj\u00f6gren's disease, to study the role of IFN\u03b1 in Sj\u00f6gren's disease. Ultrasensitive single molecule ELISA and an oligoprotein IFN signature score derived from broad capture proteomics were used to analyse samples from UKPSSR and data from the UK Biobank Pharma Proteomics Project (a subset of individuals from UK Biobank) to establish the timecourse and immune endotype associated with elevated IFN\u03b1. To address causality, we created a new transgenic mouse model of IFN\u03b1 overexpression to establish whether chronically elevated IFN\u03b1 drives this immune endotype. People with lived experience of Sj\u00f6gren's disease were involved in the design of the UKPSSR and shaping of research questions. Between Aug 1, 2009, and March 31, 2012, we identified 177 people with Sj\u00f6gren's disease in UKPSSR (mean age 57\u00b75 years [IQR 46\u00b70-65\u00b70], 163 [92%] women, 14 [8%] men, and 162 [92%] White ethnicity). In addition, between March 13, 2006, to Oct 1, 2010, we identified 47\u2008606 people without Sj\u00f6gren's disease and 257 people with Sj\u00f6gren's disease in the UK Biobank Pharma Proteomics Project, including 137 individuals sampled before diagnosis. IFN\u03b1 concentrations were elevated in 108 (61%) of 177 people with Sj\u00f6gren's disease in the UKPSSR. Oligoprotein IFN signatures were detected up to 14 years before diagnosis of Sj\u00f6gren's disease in the UK Biobank Pharma Proteomics Project. Individuals in UKPSSR with elevated IFN\u03b1 had a distinct immunological endotype characterised by cytopenia, hypergammaglobulinaemia, multiple autoantibodies, and autoimmunity against the Sj\u00f6gren autoantigen TRIM21/Ro52. In a mouse model of systemic chronic IFN\u03b1 elevation, in which IFN\u03b14 was overexpressed by conventional dendritic cells, the key features of the endotype were recapitulated and could be partly reversed by type 1 interferon receptor (IFNAR1) blockade. We found that the elevation of IFN\u03b1 drives an immune endotype of Sj\u00f6gren's disease, and elevated IFN\u03b1 can be detected over a decade before diagnosis. People with Sj\u00f6gren's disease with elevated IFN\u03b1 concentrations were broadly clinically similar to those with normal IFN\u03b1 concentrations, yet were immunologically distinct. This highlights the mechanistic heterogeneity of Sj\u00f6gren's disease and the need for immunological stratification along precision medicine principles, using high resolution biomarkers. In addition to demonstrating causal direction, biological modelling in a mouse model showed that chronic IFN\u03b1 elevation over the lifecourse had the potential to establish persistent immune dysregulation, which responded only partly to IFNAR1 blockade. These findings provide insights into Sj\u00f6gren's disease and other interferonopathic rheumatological disorders.

"42392258": "ID: 42392258\nTitle: Ablation of microglial estrogen receptor alpha predisposes male mice to diet-induced obesity.\nAbstract: Estrogen receptor alpha (ER\u03b1) signaling has metabolic and anti-inflammatory properties in addition to its impact on reproductive function. Compared to females, male mice generally exhibit greater inflammatory activation of microglia and increased susceptibility to diet-induced obesity (DIO). Given the established metabolic protective effects of estrogen, these observations raise the possibility that sex differences in microglial estrogen signaling contribute to this sexual dimorphism. In this study, we assessed metabolic and CNS histopathological properties in a mouse model with inducible microglia-specific ablation of ER\u03b1 (MG-ER\u03b1KO). Male MG-ER\u03b1KO mice developed increased weight gain and insulin resistance relative to controls during high-fat diet (HFD) feeding. Indirect calorimetry and food intake analysis revealed that reduced energy expenditure, coupled with an inadequate compensatory reduction in food intake, was the primary driver of the obese phenotype. In contrast, female MG-ER\u03b1KO mice fed HFD developed mild insulin resistance, with no change in body weight gain compared to controls, despite a similar reduction in energy expenditure. Immunohistochemical analyses of the microglial activation marker IBA1 in the mediobasal hypothalamus (MBH) revealed that female MG-ER\u03b1KO mice had an increased number of microglia without showing morphological signs of activation. In contrast, MBH microglial number was unchanged in MG-ER\u03b1KO male mice, but the cells adopted more activated morphological profiles. Finally, HFD-fed MG-ER\u03b1KO male mice had increased POMC neuron-microglia interactions but fewer overall hypothalamic POMC neurons, suggesting microglia may disrupt POMC neuron integrity to promote DIO. Together, these findings indicate that sex-specific actions of estrogen in microglia limit the metabolic complications of HFD feeding.",

Here, using IP and LC-MS/MS analyses, we identified grass carp THOC7 (CiTHOC7) as a candidate protein that interacts with SNX8. THOC7 was significantly up-regulated in all tested tissues following GCRV infection. Moreover, THOC7 suppressed virus-induced IFN 1 signaling, aggravated GCRV-induced developmental abnormalities of zebrafish embryos, and reduced their survival rates. Further investigations demonstrated that SNX8 interacted with THOC7, facilitated its phosphorylation, and promoted the association between THOC7 and TBK1, thereby suppressing TBK1 phosphorylation. Either THOC7 alone or SNX8 collaborated with THOC7 significantly suppressed GCRV-induced irf3, irf7, and ifn 1 gene transcription, IFN 1 promoter and ISRE activation, as well as IRF7 expression and IFN 1 production. Additionally, they attenuated phosphorylation of TBK1 and IRF3, while affecting IRF7 expression but not its phosphorylation. Collectively, these findings indicated that SNX8 cooperates with THOC7 to negatively regulate the IFN 1 response through the TBK1-IRF3 signaling axis, providing novel insights into the regulatory mechanism of antiviral innate immunity in grass carp.",

In this study, we compared five PARPi with different PARP-trapping capacities in PDX-derived cell lines and mouse models. Talazoparib, the strongest PARP-trapping agent, showed markedly greater efficacy than olaparib or veliparib. It triggered extensive DNA damage, micronuclei formation, and activation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway, leading to robust type I interferon and pro-inflammatory cytokine release, an effect not seen in osteosarcoma. In vivo, talazoparib also reshaped the tumor microenvironment, increasing macrophage infiltration and reducing tumor growth. In vitro, conditioned media from treated EwS cells promoted M0-like macrophage polarization towards an inflammatory M1-like status. These immunostimulatory effects were initiated by tumor-derived interferons and were absent in talazoparib-resistant and olaparib-treated EwS cells, underscoring the importance of the PARP trapping activity of PARPi rather than catalytic inhibition. Combination of talazoparib with exogenous 2'-3'-cyclic GMP-AMP (cGAMP) does not further increase phagocytosis of EwS cells when co-cultured with macrophages, and no additive effects were observed under the tested conditions. Thus, talazoparib is a potent cytotoxic agent with innate immune activation/macrophage-mediated effects, prompting further clinical evaluation in this tumor type.",

Hematoxylin and eosin(HE) staining was used to assess inflammatory cell infiltration, while luxol fast blue(LFB) staining and electron microscopy were performed to evaluate myelin sheath structure. In cell experiments, this study measured programmed cell death ligand 1(PD-L1) expression on BV2 cells and forkhead box protein p3(Foxp3) expression in Jurkat T cells co-cultured with BV2 cells, determined the C-C motif chemokine ligand 5(CCL5) concentration in the supernatant of BV2 cells, and evaluated BV2 cell chemotaxis. Western blot(WB) was performed to detect protein levels of receptor tyrosine kinase(AXL), phosphorylated AXL(p-AXL), signal transducer and activator of transcription 1(STAT1), phosphorylated STAT1(p-STAT1), and suppressors of cytokine signaling 3(SOCS3). To confirm the role of AXL, key cellular assays were repeated following inhibition of AXL. Additionally, under physiological conditions, the effects of DHA on body weight, spleen weight, and peripheral blood immune cell profiles were examined. The results showed that DHA significantly reduced disease scores, attenuated body weight loss, suppressed inflammatory infiltration, and promoted myelin sheath repair in experimental autoimmune encephalomyelitis(EAE) mice. At the cellular level, DHA upregulated PD-L1 expression on BV2 cells and Foxp3 expression in co-cultured Jurkat cells, and inhibited CCL5 release and BV2 cell chemotaxis. It also upregulated AXL, p-AXL, p-STAT1, and SOCS3 protein expression in BV2 cells. When AXL was inhibited, these effects are nullified. In healthy mice, DHA did not have any effect on their various parameters. In conclusion, DHA maintains inflammatory homeostasis in the EAE model by activating the AXL signaling pathway in microglia.",

Firstly, ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was used to identify the blood-entering components of TTWC. Then, network pharmacology and molecular docking were used to predict the potential antidepressant active components and mechanisms of TTWC. Finally, an in vitro model constructed using lipopolysaccharide(LPS)-treated BV2 cells was used to validate the main active components. A total of 38 triterpenoid components of W. cocos were detected in the blood. Thirty potential active components were obtained through screening by network pharmacology, and 122 component-disease overlapping targets were obtained, which showed that interleukin(IL)-6, tumor necrosis factor(TNF), Albumin(ALB), non-receptor tyrosine kinase(SRC), and IL-1\u03b2 might be the core targets. The Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment results indicated that the antidepressant effect of TTWC might be influenced by neuroactive ligand-receptor interaction signaling pathway, Fc \u03b5 RI signaling pathway, TNF signaling pathway, and mitogen-activated protein kinase(MAPK) signaling pathway. The molecular docking results showed that the potential antidepressant active components of TTWC had a good binding effect with the core targets. The results of cell assays showed that TTWC and nine components, including pachymic acid and pachymic acid A, reduced the secretion levels of tumor necrosis factor-\u03b1(TNF-\u03b1), IL-6, IL-1\u03b2, IL-18, and nitric oxide(NO) to varying degrees and down-regulated the protein expression levels of phosphorylated p38 mitogen-activated protein kinase(p-p38) and phosphorylated c-Jun amino-terminal protein kinase(p-JNK). Comparison of the results of the experiments in each group showed that there were differences in the potency and main targets of the components. On the basis of previous studies, the present study explored the antidepressant active components of TTWC and demonstrated that they can effectively reduce the secretion of inflammatory factors and inflammatory mediators, and realize the control of neuroinflammation through the regulation of the MAPK pathway. The results of this study showed that TTWC inhibited neuroinflammation in a multi-component, multi-target, and multi-pathway manner, thus realizing the antidepressant effect.",

Here, the deubiquitinating enzyme OTUB1 is identified as a regulator of microglial activation and CNS inflammation. In mice, microglia-specific OTUB1 deletion significantly ameliorates ischemic brain injury by reducing the pro-inflammatory activation of microglia. OTUB1 enhances Toll-like receptor (TLR) signaling through stabilizing UBC13 and TAB2, leading to the increased induction of cytokines. Notably, OTUB1 reduces the proteasomal degradation of TAB2 by reducing its K48 ubiquitination in a catalytic activity-independent manner. Moreover, microglia-confined OTUB1 deficiency also alleviates lipopolysaccharide-induced sickness behavior and experimental autoimmune encephalomyelitis in mice due to decreased neuroinflammation. Pharmacological inhibition of OTUB1 significantly mitigated ischemic stroke injury in mice. These findings reveal an important role of OTUB1 in potentiating microglial activation and neuroinflammation, providing a proof-of-principle observation for targeting OTUB1 in the treatment of TLR-associated neuroinflammatory diseases.",

Contralesional nuclei were analyzed in patients. Group differences and 3-month outcome associations were assessed. Functional independence was defined as modified Rankin Scale score 0-2, and poor outcome as 3-6. Linear mixed-effects models, analysis of covariance, logistic regression, receiver operating characteristic analysis; p\u2009<\u20090.05 was significant. Compared with healthy controls, patients showed higher \u03c7para in all seven nuclei, including the dentate nucleus (84.065\u2009\u00b1\u200915.086 vs. 76.172\u2009\u00b1\u200911.387\u2009ppb) and thalamus (30.633 [28.036, 34.454] vs. 28.867 [26.749, 31.804] ppb), and higher \u03c7dia in the caudate, putamen, red nucleus, thalamus, and dentate nucleus (dentate nucleus: -18.916\u2009\u00b1\u20096.496 vs. -22.220\u2009\u00b1\u20095.002\u2009ppb). Poor 3-month outcome was independently associated with higher dentate nucleus \u03c7para (OR, 1.07; 95% CI, 1.03-1.11), higher dentate nucleus \u03c7dia (OR, 1.14; 95% CI, 1.04-1.26), and higher thalamus \u03c7para (OR, 1.22; 95% CI, 1.08-1.38). The combined model, incorporating conventional model factors (age, sex, stroke subtype, NIHSS score, and infarct volume) and \u03c7-separation metrics, outperformed the conventional model (AUC, 0.862 vs. 0.757). \u03c7-separation revealed iron- and myelin-related susceptibility alterations in contralesional DGM nuclei after AIS. Susceptibility metrics in the dentate nucleus and thalamus were associated with poor 3-month functional outcome. 2. Stage 1. Stroke recovery may depend not only on the visible infarct lesion, but also on distant brain regions related to functional independence. Quantitative susceptibility mapping can detect tissue susceptibility alterations, but cannot separate iron\u2010related and myelin\u2010related sources, which may obscure pathophysiological changes relevant to poor recovery. The researchers used \u03c7\u2010separation to assess these sources in contralesional deep gray matter nuclei, meaning nuclei opposite the infarct lesion, after acute ischemic stroke. Alterations in the dentate nucleus and thalamus were associated with poorer independence after 3\u2009months, helping clarify remote brain changes during recovery.",
"42393712": "ID: 42393712\nTitle: The mitochondrial protease, LonP1, is a potential cardioprotective target for attenuating doxorubicin-induced cardiomyocyte death.\nAbstract: Doxorubicin (DOX), a first-line chemotherapeutic agent, has been linked to severe off-target cardiotoxicity in the clinic. Previous works suggest that mitochondria are key mediators of this cardiotoxicity. Leakage of mitochondrial contents after DOX treatment, including mitochondrial DNA (mtDNA), is thought to activate apoptotic and inflammatory signaling pathways implicated in cardiomyocyte cell death. Whether the master mitochondrial protease, LonP1, can dampen these pathways and improve cardiomyocyte viability following DOX treatment remains unknown. Human cardiac cells (AC-16) and primary (1\u00b0) human cardiomyocytes were subjected to DOX treatment, followed by bulk RNA-Seq, RT-qPCR, qPCR, and immunoblotting to assess apoptotic signaling, inflammatory signaling, mtDNA release, and LonP1 expression, respectively. Lentivirus transduction of AC-16 cells was used to generate both knockdown (KD) and overexpression (OE) LonP1 cell lines to determine the effects of altered LonP1 levels on DOX-induced apoptosis and mtDNA release. Further, levels of mitochondrial DNA (mtDNA) were measured using qPCR from serum samples obtained from patients undergoing DOX treatment to assess the clinical relevance of released mtDNA as a potential biomarker for the development of DOX cardiotoxicity. DOX treatment of AC-16 cells, as well as 1\u00b0 human cardiomyocytes, upregulated both apoptotic and inflammatory signaling in both cell models. Increased LonP1 levels were also observed under DOX treatment in AC-16 cells and 1\u00b0 human cardiomyocytes. Likewise, DOX increased mtDNA release from both cell lines, both prior to, and as a sequel to cell death. Decreasing LonP1 levels exacerbated DOX-mediated apoptotic signaling and mtDNA release, whereas overexpression of LonP1 attenuated these effects. Furthermore, DOX treatment in cancer patients increases plasma mtDNA levels. These findings suggest LonP1 plays a protective role in the heart following DOX treatment, supporting LonP1 as a potential novel therapeutic target for prevention of DOX cardiotoxicity. Patterns of mtDNA release within patients undergoing DOX treatment also highlight the potential of mtDNA as a potential biomarker and target for prevention of DOX cardiotoxicity, justifying the need for more extensive, prospectively monitored cohort studies to expand upon these findings and statistically model mtDNA release patterns.",
"42393750": "ID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.",
"42393898": "ID: 42393898\nTitle: Heterocyclic Scaffolds as Therapeutic Agents in Multiple Sclerosis: Mechanisms and SAR Study.\nAbstract: Multiple sclerosis (MS) is a progressive, immune-mediated condition characterized by the destruction of myelin, the protective insulation surrounding nerve fibers. This ongoing assault triggers a cascade of damage, including persistent inflammatory responses, loss of myelinproducing oligodendrocytes, axonal degradation, and cumulative neurological impairment. While motor and sensory difficulties are hallmark features, patients frequently contend with less visible but equally debilitating symptoms such as cognitive dysfunction, profound fatigue, affective disorders, nerve pain, and autonomic instability. These often-overlooked manifestations critically impact well-being and functional capacity. The pathophysiology of MS is increasingly understood as a network of overlapping cellular and molecular dysfunctions. Alongside irregularities in the endocannabinoid signaling network, key contributors include aberrant immune communication, persistently activated microglia, impaired mitochondrial energy production, and dysregulated activity of enzymes like PDE7, MAGL, ROCK, and PADs. These interconnected pathways collectively drive disease initiation and advancement. This analysis synthesizes established information on current FDA-approved treatments for MS and examines promising novel small-molecule compounds aimed at specific disease-relevant targets. A significant focus is placed on medicinal chemistry advancements, particularly the design and optimization of heterocyclic compounds. Scaffolds incorporating quinolines, pyrimidines, indoles, and related nitrogen-containing structures demonstrate considerable potential for conferring immunomodulation, reducing inflammation, and protecting neural tissue. By evaluating structure-activity relationships, binding mechanisms, and strategic drug design, this review offers an integrated perspective to inform the creation of new, targeted therapies for MS.",
"42394260": "ID: 42394260\nTitle: Therapeutic potential of liver X receptor agonist GW3965 in preserving myelin integrity following traumatic brain injury.\nAbstract: Myelin, a multilamellar sheath produced by oligodendrocytes, ensures rapid electrical impulse conduction and maintains axonal integrity in the central nervous system (CNS). Demyelination, the loss or disruption of this protective sheath, is a key pathological consequence of traumatic brain injury (TBI) that exacerbates axonal injury and ultimately contributes to persistent cognitive and motor deficits. Currently, no therapies specifically target demyelination after TBI. Liver X receptors (LXRs) regulate lipid metabolism, cholesterol homeostasis, and inflammation in CNS cells. Activation of LXRs promotes oligodendrocyte maturation, enhances myelin gene expression, and facilitates remyelination. We hypothesized that GW3965, a synthetic LXR agonist, would enhance myelination and improved cognitive outcomes after TBI. C57BL/6 mice were subjected to mild TBI using a closed-head injury model and treated orally with GW3965 (10\u00a0mg\u00b7kg-1\u00b7day-1) starting 1\u2009day post-injury for 3\u2009weeks. Cognitive and behavioural performance was assessed using the modified Neurological Severity Score, open-field, novel object recognition, and Y-maze tests. On day 28 post-TBI, cortical tissues were analysed by immunofluorescence and a ProteinSimple\u00ae capillary-based immunoassay. TBI caused sustained neurological and cognitive impairments characterized by demyelination, axonal injury, and neuronal loss. GW3965 treatment significantly preserved mature oligodendrocytes and myelin, reduced axonal degeneration, and improved behavioural performance. This study provides novel insights into the role of LXR activation via GW3965 in mitigating TBI-induced demyelination and axonal injury, while preserving mature oligodendrocytes and cognitive and behavioural outcomes. These findings advance our understanding of brain repair mechanisms and highlight LXR activation as a promising therapeutic strategy for TBI-related neurological damage.",

Direct comparisons of central and peripheral diagnostic findings across these entities remain limited. We, therefore, performed a systematic study assessing nervous system involvement in CCPD, using magnetic resonance imaging (MRI), nerve ultrasound (US), and nerve conduction study (NCS) and compared findings to MS and CIDP controls. We conducted a descriptive case study including 4 CCPD patients, 13 CIDP patients, and 10 MS controls. All subjects underwent a standardized protocol of NCS and US. In addition, MS and CCPD patients also underwent brain and spinal cord MRI. Cerebrospinal fluid testing was performed in 20/27 patients. NCS revealed electrodiagnostic features suggestive of demyelination in all CCPD and CIDP patients, fulfilling the electrodiagnostic criteria for CIDP. We found motor conduction abnormalities in two MS patients, not fulfilling criteria for demyelination. US showed a similar pattern of multifocal nerve enlargement in CCPD and CIDP patients, while three MS patients also demonstrated mild proximal median nerve enlargement. Finally, CSF oligoclonal bands were only found in MS patients. Peripheral diagnostic tools reveal strikingly similar electrophysiological and morphologic features in CCPD and CIDP, underscoring a potential overlap in their disease mechanisms and the challenges of distinguishing these entities based on peripheral nerve assessment alone. Our findings further suggest that US could serve as a potentially useful screening tool in patients with predominantly central nervous system demyelinating syndromes and suspected peripheral involvement, helping to guide subsequent electrophysiological testing.",
"42394822": "ID: 42394822\nTitle: STING agonist 2'3'-cGAMP as an effective adjuvant for HPV16 peptide vaccine enhances anti-tumor immunity in TC-1 mice models.\nAbstract: Adjuvants are critical for enhancing vaccine immunogenicity. The agonists in cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway have demonstrated robust immune activation in preclinical models. Peptide vaccines targeting T cell epitopes of high-risk human papillomavirus (HPV) E6 and E7 represent a promising immunization strategy. To improve immunogenicity, we utilized the STING agonist 2'3'-cGAMP as an adjuvant and evaluated its ability to enhance immune responses and antitumor efficacy. The immunogenicity and efficacy of a candidate vaccine, consisting of the HPV16 E743-77 peptide adjuvanted with 2'3'-cGAMP, were evaluated in established TC-1 tumor transplantation models with different initial tumor sizes (2-3 mm and 5-6 mm in diameter). Tumor-bearing mice received three weekly peritumoral subcutaneous vaccine doses. The effects on tumor suppression, antigen-specific cytotoxic T lymphocyte (CTL) response induction, and related immune mechanisms were investigated both in vitro and in vivo. Immunization with the E743-77 peptide adjuvanted by 2'3'-cGAMP significantly suppressed tumor growth and elicited high levels of Interferon (IFN)-\u03b3 and Granzyme B in CD8+ cytotoxic T lymphocytes. The vaccine also enhanced the differentiation of natural killer (NK) cells, dendritic cells (DCs), and M1-type macrophages, reduced Myeloid-derived suppressor cells (MDSCs), and increased INF-\u03b2 levels, as well as promote lymphocyte infiltration and remodeling in tumor immune microenvironment (TME). Mechanistically, 2'3'-cGAMP promoted DC maturation, enhanced T cell proliferation and activation, and strengthened antigen-specific CTL responses by activating the STING-TBK1-IRF3 and STING-NF-\u03baB pathways in peptide-loaded DCs. The STING agonist 2'3'-cGAMP serves as an effective adjuvant that enhances the therapeutic efficacy of an HPV16 peptide vaccine. These findings indicate its potential as a candidate therapeutic for HPV16 persistent infection and associated malignancies.",

This review explains how non-invasive physical stimulation (NIPS) reprograms TAMs via defined couplings between physical inputs and signaling pathways. Hypoxia-tolerant photodynamic strategies and mild photothermal heating reset hypoxia- and lactate-driven programs; cavitation-dominant ultrasound and sonodynamic therapy trigger danger signaling and reactive oxygen species; ultrasound microbubble destruction provides endothelial repair cues; nanosecond pulsed electric fields activate cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway; piezoelectric materials convert mechanical input into calcium-dependent transcription; and appropriately dosed radiotherapy elicits immune-active responses while avoiding hypoxia-driven M2 recruitment. Across models, these regimens promote pro-inflammatory reprogramming, normalize aberrant vasculature, and strengthen antitumor immunity while restraining immunosuppression. We synthesize parameter windows, delivery options, and combination strategies with checkpoint blockade and macrophage-directed agents to guide the translation of NIPS into precise, low-toxicity TAM-targeted immunotherapy.",

Cyclophilin A (CypA), when released into the extracellular space (designated as eCypA), may participate in inflammatory reactions and vascular dysfunction. However, its role in regulating neuroinflammation and BBB injury in AIS, as well as the therapeutic potential of targeting eCypA remain unclear. ELISA was used to detect eCypA release in serum from 22 AIS patients (17 mild, 5 severe; 13 males, 9 females; mild: age 65.41\u202f\u00b1\u202f10.20\u202fyears, NIHSS 2.88\u202f\u00b1\u202f1.45; severe: age 64.00\u202f\u00b1\u202f5.04\u202fyears, NIHSS 9.40\u202f\u00b1\u202f3.29; blood sampled within 48\u202fh of onset), in serum/cerebrospinal fluid (CSF) from transient middle cerebral artery occlusion (tMCAO) rats, and in supernatants from BV2 (microglia) or bEnd.3 (brain microvascular endothelial cells) exposed to oxygen-glucose deprivation/reoxygenation (OGD/R) or lipopolysaccharide (LPS). Nine-week-old male Sprague-Dawley rats (n =\u202f5 per group) underwent 1.5\u202fh of tMCAO via the intraluminal suture method followed by 24\u202fh of reperfusion before sampling. These rats received intracerebroventricular injection of cyclophilin A-binding heptameric peptide (C46) before tMCAO establishment. Cerebral infarct volume was measured via TTC staining. BBB permeability was assessed by Evans blue extravasation. Western blot was employed to determine protein levels of tight junction (TJ) proteins, matrix metalloproteinases (MMPs) and proinflammatory mediators. Microglial activation was evaluated by immunofluorescence. eCypA levels were significantly elevated in AIS patient serum (1.74\u202f\u00b1\u202f0.23\u202fng/mL in mild, 2.39\u202f\u00b1\u202f0.09\u202fng/mL in severe vs. 1.30\u202f\u00b1\u202f0.19\u202fng/mL in healthy controls, p <\u202f0.001), in tMCAO rat serum (2.57\u202f\u00b1\u202f0.14 vs. 1.62\u202f\u00b1\u202f0.07\u202fng/mL, p <\u202f0.001) and CSF (2.14\u202f\u00b1\u202f0.23 vs. 1.47\u202f\u00b1\u202f0.19\u202fng/mL, p <\u202f0.001), as well as in the supernatants of OGD/R-challenged BV2 (0.92\u202f\u00b1\u202f0.01 vs. 0.55\u202f\u00b1\u202f0.03\u202fng/mL, p <\u202f0.001) and bEnd.3 cells (1.10\u202f\u00b1\u202f0.05 vs. 0.52\u202f\u00b1\u202f0.03\u202fng/mL, p <\u202f0.001) and LPS-induced BV2 cells (1.12\u202f\u00b1\u202f0.08 vs. 0.56\u202f\u00b1\u202f0.13\u202fng/mL, p <\u202f0.001) compared with their respective control groups. The eCypA inhibitory peptide C46 effectively improved neurological function, reduced cerebral infarct volume and edema in tMCAO rats. Moreover, C46 mitigated BBB permeability, preserved the expression levels of TJ proteins, and suppressed the activation of MMPs in tMCAO rats and OGD/R-treated bEnd.3 cells. Meanwhile, C46 administration inhibited microglial activation and downregulated the expression of proinflammatory mediators both in vivo (tMCAO rats) and in vitro (OGD/R- or LPS-induced BV2 microglia). eCypA, released by microglia and brain microvascular endothelial cells under ischemic-hypoxic and inflammatory conditions, serves as a critical pathogenic mediator that drives neuroinflammation and BBB disruption in AIS. Targeting eCypA with C46 peptide effectively abrogates these pathological cascades, thereby supporting eCypA as a novel therapeutic target for AIS.",

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

Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.",

Previous studies in mice have shown that stimulating type I interferon (IFN) signaling during BCG vaccination can bolster protection against Mycobacterium tuberculosis , yet clinically feasible delivery strategies for this approach are lacking. Adenoviral vectors, which induce potent type I IFN responses and are utilized in approved vaccine platforms, represent a promising adjuvant strategy. To evaluate the host immune response to this combination, bone marrow-derived murine macrophages were co-infected with replication-deficient adenovirus and BCG. Adenovirus-infected macrophages elicited a robust type I IFN response via the cGAS/STING pathway. Compared to BCG infection alone, co-infected macrophages exhibited additive expression of genes with known host-protective roles against M. tuberculosis . Conversely, co-infection with BCG suppressed adenovirus-induced type I IFN signaling and diminished the production of IFN-stimulated genes compared to adenovirus infection alone. Together, these findings reveal a complex regulatory interplay during adenovirus and BCG co-infection. While BCG partially restricts adenoviral IFN induction, the co-infection still drives an enhanced host-protective gene profile, suggesting that adenoviral vectors could serve as a viable platform to modulate innate immunity and improve BCG vaccine efficacy. Tuberculosis (TB) remains the leading cause of death by a single infectious organism with approximately 1.25 million deaths annually. M. bovis BCG remains the only approved vaccine for TB; however, its efficacy against the contagious and most common pulmonary form of the disease is limited. There have been numerous attempts to improve BCG efficacy, but these approaches have not resulted in any clinically approved vaccine. We propose that BCG combined with a replication-deficient adenovirus presents a way to bolster vaccine-conferred protection as the combination may elicit a robust innate immune response and drive a more protective T cell response. Moreover, BCG and replication-deficient adenoviruses have well-assessed safety profiles and decades of studies regarding their use in patients. The significance of our work is in leveraging their complementary immunology to function as a combined vaccine platform. This approach presents a novel and clinically feasible approach to improve the BCG vaccine.",

This inflammatory process unfolds years before clinical symptoms, creating an opportunity for early intervention. In vivo imaging technologies that could detect and quantify microglial reactivity are therefore essential for early diagnosis, patient stratification, and evaluating emerging immunomodulatory therapies that target this fundamental driver of PD progression. Yet no standardized, sensitive, and specific technology currently achieves this goal. Molecular magnetic resonance imaging (mMRI) is uniquely suitable to address this problem because it integrates inherent high spatial resolution and soft-tissue contrast of conventional MRI with molecularly targeted contrast agents, enabling simultaneous acquisition of anatomical detail and functional/biological information at submillimeter isotropic resolution. Here we present a novel mMRI probe designed to specifically target colony stimulating factor-1 receptor, expressed primarily on microglia in the brain. In silico data show that the targeting ligand binds the extracellular Ig domain of the receptor. In vitro cell uptake studies with both murine and human microglia cell lines show that the probe binds the receptor triggering active cell uptake and in vivo MRI enabled effective separation of the A53T mouse model of Parkinson's disease from control mice using radiomics-assisted MR image analysis. Ex-vivo immunohistochemical analysis showed signal from the probe largely in the cytosolic compartment of IBA-1 reactive cells, confirming that the observed in vivo MRI signal is due primarily to retention of the agent by microglia. This novel technology has the potential to interrogate the rgional presentation of microglial activation in PD. A microglia targeted MRI probe generates disease-specific contrast after injection, clearly distinguishing A53T Parkinsonian mice from controls.",

The admixture of schizophrenia and affective psychoses cases could be a roadblock if these differ in cellular pathology. We examined cognitive functioning (MATRICS) and hippocampal cellular pathologies based on metabolite biomarker concentrations ( 1 H-MRSI), using categorical and transdiagnostic classifications in 80 participants: 22 non-psychotic affective disorder (NP-aff), 25 healthy controls (HC), and 33 with psychosis (Psy), including 20 schizophrenia and 13 affective psychoses (aff-P) cases. NP-aff and HC had similar total cognition (46.64\u00b112.01 vs 41.10\u00b117.88), both superior to Psy (28.34\u00b112.34; p's<0.01). Mean metabolite concentrations were similar across all groups but showed significant within-group associations to cognitive tests. For HC, total cognition, working memory and reasoning deficits were associated with reduced neuronal integrity (-.414, -.422, -.433, p's<.05), although no biomarker predicted total cognition in the clinical groups. For NP-aff, elevated myelin/membrane concentrations accompanied cognitive deficits; significantly so for visual learning deficits (.446, p<.05), which were also associated with decreased glia (-.503, p<.05). Opposite NP-aff, reduced myelin/membrane concentrations predicted cognitive deficits in Psy (-.514, p<.05). Separating schizophrenia from aff-P on social cognition showed reduced glutamate/excitation in schizophrenia (-.673, p<.05) but higher myelin/membrane turnover and neuronal integrity concentrations in aff-P (.575, .581, p's<.05). Schizophrenia and affective psychosis significantly differed for biomarkers of cellular pathology related to social cognition. Distinctly different underpinnings for cognition were also identified for other groups, aligning with DSM-5 and ICD disorder based categories. These findings include support for heterogeneous, but not transdiagnostic, conceptualizations of cognition and psychosis.",
"42395866": "ID: 42395866\nTitle: The role of SUMOylation in regulating proteins that drive neuronal disease progression.\nAbstract: SUMOylation is a post-translational modification in which a Small Ubiquitin-like Modifier (SUMO) protein is reversibly attached to a lysine residue on a target protein in an ATP-dependent process. This modification can affect the function of target proteins by enhancing their stability or changing cellular translocation, thereby making SUMOylation a critical regulator in the pathogenesis of multiple diseases. The functional consequences of SUMOylation, however, are highly context dependent. In Alzheimer's disease, SUMOylation stabilizes proteins that drive disease progression and enhances neurotoxicity, thereby exacerbating these conditions. Similarly, in Progressive Supranuclear Palsy, SUMO-1 conjugation stabilizes truncated tau and blocks its ubiquitination, whereas SUMO-2/3 conjugation promotes Tau clearance and recovery from neuroinflammation, illustrating how distinct SUMO paralogues can exert opposing effects within the same disease. Conversely, increased SUMOylation can be neuroprotective in cerebral ischemia and Parkinson's disease by promoting autophagic clearance of pathogenic proteins. Beyond alterations in protein stability, aberrant SUMOylation can also lead to mis-localization of target proteins, which has been identified as a pathogenic mechanism in disorders such as Huntington's disease and Amyotrophic Lateral Sclerosis that results in impaired clearance and pathogenic buildup, which results in neuronal death. From a therapeutic standpoint, the SUMO inhibitor TAK-981 has shown promise in both Multiple Sclerosis and in pre-clinical glioblastoma models, underscoring the translational potential of targeting of this pathway. This review examines the multifaceted role of SUMOylation across diverse neurological conditions, evaluates the therapeutic potential of SUMO inhibitors and activators, and highlights the opportunities and challenges of modulating this pathway in currently incurable neurological disorders.",

In the peripheral nervous system, Schwann cells produce myelin. While much is known about the molecules and processes involved in mammalian myelination, little is known about it in other vertebrate groups. In this study, we examined myelin development in the peripheral nerves of the turtle Trachemys scripta using qPCR, RNA sequencing, immunofluorescence, and TEM. Our findings indicate that in T. scripta, myelination begins during the late stages of embryonic development and continues beyond hatching. Expression profiles reveal both conservation and divergence of core myelination components between mammals and amphibians; however, direct gene-level comparisons across species require further investigation given our small sample size. The upregulation of orthologous myelin genes in the turtle PNS supports the idea that these components are conserved, although their timing, regulation, or network structure may differ across tetrapods. We based our inference of conservation on orthology and the coordinated expression of key myelin genes (e.g., ErbB2, Mag, Mpz, Mbp, Pmp22) in T. scripta. TEM analysis of turtle sciatic nerves shows myelin rings in a few axons starting at stage 21, increasing significantly by stage 24, and becoming prominent in most axons of the adult nerve. Furthermore, antibodies against MPZ, DRP2, and Kv1.1 indicate that T. scripta adult peripheral nerves at various axial levels contain myelin segments with structures consistent with appositions and Schmidt-Lanterman incisures. Overall, this is the first study of PNS myelin development in a reptile, demonstrating that myelination is a highly conserved process in vertebrates.",

Typically, patients present in their fifth decade with extranodal disease in the upper aerodigestive tract. Pediatric NKTCL is rare, with no established pediatric standard of care treatment. We describe the case of a healthy 15-year-old Filipino-Canadian male who presented with transverse colon perforation and was diagnosed with extranodal EBV\u2009+\u2009nasal type NKTCL of the gastrointestinal (GI) tract. After a complicated initial surgical course, we elected to treat him using six cycles of modified SMILE (dexamethasone, PEG-asparaginase, ifosfamide, and etoposide) chemotherapy and consolidative hematopoietic stem cell transplant (HSCT). The post-HSCT course involved cytomegalovirus reactivation (buccal lesions, viremia); adenovirus reactivation (positive nasal swab, viremia); zoster reactivation; acute and chronic oral/upper GI graft-versus-host disease (GVHD); chronic skin GVHD (vitiligo); and avascular necrosis. At the most recent follow-up, surveillance imaging and investigations at 2\u2009years post-transplant showed durable CR1 and 100% donor chimerism. To our knowledge, this is the fourth reported case of primary GI NKTCL in a pediatric/adolescent patient; the only patient treated with an asparaginase-containing regimen; and the only patient to undergo consolidative HSCT. Our patient's outcome supports the utilization of an aggressive approach to treat GI NKTCL in young, fit patients similar to Stage III/VI nasal NKTCL. Our case also highlights unique treatment considerations for adolescent cancer patients, including delayed diagnoses and lack of standardized protocols.",

Symptoms start in the sixth or seventh decade of life, presenting sensory polyneuropathy with sensory ataxia, paresthesia, mild motor deficit, and tremor of upper extremities. The neurophysiological features are compatible with length-dependent demyelination. It is caused by monoclonal gammopathy of the IgM type produced by clonal B cells. In recent years the monoclonal anti-CD20 antibody has become the preferred first-line treatment, but with limited efficacy. We identified a cohort of 42 patients diagnosed with anti-MAG polyneuropathy. Clinical data were collected retrospectively, and flow cytometry files and immune histochemistry slides were reassessed. We report that in most cases of anti-MAG polyneuropathy, the monoclonal IgM is kappa-restricted, the B-cell population shows lymphoplasmacytic differentiation, MYD88L265P mutation is a frequent finding, and the clonal B-cell population includes plasma cells. These findings most likely explain the low efficacy of rituximab monotherapy. We found the burden of symptoms to be high among patients with anti-MAG polyneuropathy as most of our patients had received intravenous immunoglobulin infusions and/or B-cell-directed treatment. We suggest that future treatment protocols for anti-MAG polyneuropathy should incorporate plasma cell-directed drugs. Furthermore, we found complement receptor 1 (CD35) to be down regulated on clonal B lymphocytes but not on normal B lymphocytes in these patients. We suggest that this may be a common feature of clonal B lymphocytes in chronic lymphoproliferative diseases.",

However, the analgesic effects of orally administered, cannabidiol are limited by low bioavailability and a short half-life. Therefore, this study investigated the effects of intrathecal (i.t.), cannabidiol administration on neuropathic pain, focusing on spinal 5-HT1A receptors and microglial modulation. Male C57BL/6 mice were subjected to neuropathic pain-induced by chronic constriction injury (CCI). Mechanical nociceptive thresholds were assessed using von Frey filaments. The involvement of spinal 5-HT1A receptors was examined by i.t. administration of the selective antagonist WAY-100635. mRNA expression, IL-10, and TNF-\u03b1 levels, and microglial activation were evaluated. Intrathecal, cannabidiol significantly reversed mechanical allodynia, producing a more potent and prolonged antinociceptive effect than oral administration. This effect was abolished by WAY-100635, indicating spinal 5-HT1A receptor involvement. Moreover, i.t. cannabidiol increased spinal IL-10 levels and 5-HT1A receptor mRNA expression, while reducing microglial activation. In vitro, cannabidiol attenuated microglial activation and significantly reduced TNF-\u03b1 production. In conclusion, i.t. cannabidiol effectively alleviates neuropathic pain in mice, with findings that may suggest the involvement of spinal mechanisms associated with 5-HT1A receptor-related signaling and modulation of microglial activation.",

However, the complex relationships between WMLs and the neuropathological changes of PD remain unclear. In this study, we comprehensively elucidated the spatiotemporal dynamics of WMLs in rotenone-, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD models, and \u03b1-synuclein (\u03b1-Syn) (A53T) transgenic mice. The results showed that WMLs occurred across multiple brain regions and gradually aggravated as PD models progressed. Notably, WMLs emerged as early pathological events of PD prior to dopaminergic neuronal loss. Consistently, WMLs-related axial movement disorders, including gait and balance impairments, preceded those caused by nigrostriatal injury. Further in vitro studies revealed that oligodendrocyte precursor cells (OPCs) dysfunction caused by 1-methyl-4-phenylpyridinium (MPP\u207a) or \u03b1-Syn could induce dopaminergic axonal breakage and neuronal damage, confirming myelination disorder promoted dopaminergic neuronal degeneration. This finding was certified in additional in vivo studies using lysophosphatidylcholine (LPC)-induced demyelination models. The results validated that WMLs could independently induce dopaminergic neuronal damage and nigrostriatal pathway-related movement disorders. Moreover, comorbid WMLs in PD mice further aggravated this process. In summary, our findings uncovered the spatiotemporal characteristics of WMLs and their contribution to PD pathological development, highlighting that targeting WMLs might be a potential strategy for PD intervention.",

As frontline sentinels of the neuroimmune system, BAMs perform essential functions in immune surveillance, barrier integrity maintenance, and homeostatic regulation, yet their unique biology and disease-associated roles remain incompletely characterized compared to parenchymal microglia. This review aims to synthesize current knowledge on BAM ontogenetic origins, compartment-specific heterogeneity, transcriptional programs, and functional outputs in both health and neurological disorders. We conducted a comprehensive literature analysis integrating findings from lineage tracing studies, single-cell RNA sequencing, spatial transcriptomics, and functional interrogation in animal models of disease. The results reveal that BAMs exhibit remarkable cellular diversity shaped by distinct ontogenetic origins-primarily yolk sac-derived erythro-myeloid progenitors with variable contributions from fetal liver and postnatal monocytes depending on anatomical compartment. Compartment-specific marker combinations (CD206, LYVE1, CD163, MHCII) define functionally distinct subsets, and core transcriptional regulators including PU.1 and IRF8 maintain BAM identity while CSF-1/IL-34-CSF1R signaling governs survival and renewal. In neurological disorders including ischemic stroke, Alzheimer's disease, multiple sclerosis, and brain tumors, BAMs display pronounced double-edged roles, transitioning from protective homeostatic guardians to pathogenic drivers depending on disease stage and microenvironmental context. This comprehensive analysis establishes a unified framework for understanding BAM biology and identifies critical opportunities for developing subset-specific therapeutic strategies targeting these interface macrophages in neurological diseases.",
"42397737": "ID: 42397737\nTitle: STING-dependent peripheral inflammaging drives neurodegeneration via extracellular vesicles.\nAbstract: All animals age. However, aging is a heterogeneous process, and individual organisms age differently. Moreover, within the same organism, cells or organs do not age at the same speed. For instance, neurodegeneration, a hallmark of aging, generally manifests later than other peripheral aging signs. The genetic determinants of aging are not completely understood. Gain-of-function (GoF) mutations in leucine-rich repeat kinase 2 (LRRK2GoF) are major genetic risk factors for Parkinson's disease (PD). By analyzing PD patients and LRRK2GoF mice, we show that PD represents an accelerated aging disorder driven by STING-dependent inflammation. This inflammation begins peripherally, disrupts the blood-brain barrier, and causes dopaminergic neurodegeneration. Mechanistically, aging or LRRK2GoF causes endolysosomal decline, resulting in cytosolic self-DNA accumulation and the release of DNA-containing extracellular vesicles (EVs) that activate the cGAS-STING pathway within and between cells. Our findings identify LRRK2GoF as a key driver of accelerated aging and systemic inflammaging through DNA-containing EVs, highlighting potential therapeutic targets to counteract inflammaging and neurodegeneration.",
"42398134": "ID: 42398134\nTitle: FGF17 synergistically targets neuronal survival and oligodendrogenesis to restore stroke deficits.\nAbstract: Stroke remains a leading cause of long-term disability, and recovery is often limited by impaired neurorestoration and glial scar-mediated inhibition of axonal regeneration. Although fibroblast growth factor 17 (FGF17) regulates oligodendrocyte plasticity during aging, its therapeutic potential and underlying mechanisms in ischemic stroke remain unclear. We investigated whether FGF17 could promote functional recovery by enhancing neuronal restoration and overcoming glial scar-associated inhibition. Fgf17-positive cell distribution was mapped using Fgf17-reporter mice (Fgf17CreERT2/+;Rosa-CAG-LSL-tdTomato). Focal ischemia was induced in the motor cortex and anterior cingulate cortex of wild-type and Fgf17-deficient (Fgf17-/-) mice via photothrombosis. Recombinant FGF17 was administered intranasally. Functional recovery was evaluated using motor and cognitive behavioral tests. Mechanistic studies were performed using viral tracing, immunofluorescence, and molecular assays focusing on the extracellular signal-regulated kinase (Erk)-serum response factor (SRF) and phospholipase C gamma (PLC\u03b3)-cyclic adenosine monophosphate (cAMP) signaling pathways. FGF17 was predominantly expressed in neurons, whereas its receptor, fibroblast growth factor receptor 3 (FGFR3), was widely distributed. Fgf17-/- mice exhibited larger infarcts and more severe functional deficits, whereas intranasal FGF17 significantly improved motor and cognitive outcomes in both wild-type and knockout mice. Mechanistically, FGF17 promoted oligodendrogenesis and myelin repair by upregulating SRF through the Erk signaling pathway. Concurrently, FGF17 activated the PLC\u03b3-adenylyl cyclase axis, increased intracellular cAMP levels, and enabled axonal regeneration within the inhibitory microenvironment through downregulation of mRNA levels of oligodendrocyte myelin glycoprotein, neurite outgrowth inhibitor A, and myelin-associated glycoprotein. In addition, FGF17 enhanced neuronal survival and preserved dendritic spines via the PI3K-Akt pathway. Overall, FGF17 promotes oligodendrogenesis and enhances the intrinsic regenerative capacity of neurons. These findings identify FGF17 signaling as a promising therapeutic target for neurorestoration after stroke.",

This study investigates the mechanisms underlying PDN and aims to identify potential molecular treatment targets. Male C57BL/6\u00a0J wild-type mice were employed to establish a PDN model, receiving intrathecal administration of shRNA targeting Galectin-3 (sh-Gal-3), shRNA targeting YTHDF1 (sh-YTHDF1), a YTHDF1 overexpression vector, or the m6A inhibitor 3-deazaadenosine (3-DAA), either individually or in combination. Macrophages underwent gene knockdown or overexpression and/or treatment with the glycolysis inhibitor 2-deoxy-d-glucose (2-DG) or 3-DAA. Diabetes was confirmed by monitoring blood glucose levels. Pain behavior was evaluated using mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) assessments. Expression levels of Gal-3 and YTHDF1 were analyzed via Real-time PCR and Western blot, while myelin phagocytosis was evaluated through immunofluorescence and/or transmission electron microscopy. Glycolysis was assessed by measuring glucose uptake, lactate production, extracellular acidification rate (ECAR), and oxygen consumption rate (OCR). The RNA pull-down assay facilitated the detection of YTHDF1 binding to Gal-3 mRNA, and the half-life of Gal-3 mRNA was measured following transcription blockade using actinomycin D. Additionally, meRIP-qPCR assessed the m6A modification on Gal-3 mRNA. In vivo analyses revealed upregulation of Gal-3, which colocalized with IBA1. Silencing Gal-3 alleviated mechanical allodynia and diminished myelin phagocytosis. In vitro, Gal-3 silencing inhibited glycolysis, while Gal-3 overexpression enhanced myelin phagocytosis, an effect reversed by 2-DG treatment. Furthermore, high glucose stimulation elevated YTHDF1 expression, subsequently increasing Gal-3 levels; this induction was abrogated by YTHDF1 knockdown. Mechanistically, YTHDF1 enhanced Gal-3 mRNA stability through an m6A-dependent mechanism, promoting glycolysis and myelin phagocytosis. Consistently, YTHDF1 overexpression exacerbated PDN symptoms and myelin phagocytosis in vivo, which were mitigated by YTHDF1 knockdown or 3-DAA administration. YTHDF1 enhances Gal-3 mRNA stability and expression via an m6A-dependent mechanism, thereby facilitating glycolysis and myelin phagocytosis in PDN.",

Although East Asia was historically regarded as a low-prevalence region, recent evidence suggests a rising MS burden, yet region-wide analyses of long-term trends and future projections remain limited. Using data from the Global Burden of Disease (GBD) 2021 study, we assessed MS burden in China, Japan, South Korea, North Korea, and Mongolia from 1990 to 2021. Age-standardized prevalence (ASPR), incidence (ASIR), mortality (ASMR), and disability-adjusted life years (DALYs) were analyzed, with temporal trends quantified using estimated annual percentage change (EAPC) and future burdens projected to 2041 through autoregressive integrated moving average (ARIMA) models. Between 1990 and 2021, ASPR in East Asia steadily increased, while ASDR declined. Mongolia consistently carried the highest burden, whereas China experienced the fastest growth, with ASPR projected to rise by more than 80% by 2041. Japan and South Korea showed relatively stable patterns, while North Korea exhibited moderate increases. Across all countries, females consistently bore higher burdens than men, and MS indicators were positively correlated with the Sociodemographic Index (SDI). Overall, the burden of MS in East Asia is increasing, with China projected to experience the steepest rise by 2041 and Mongolia continuing to carry a disproportionately high load. This study integrates long-term trends, cross-country comparisons, and gender-specific analyses to evaluate the burden of MS in East Asia, providing relevant evidence for formulating region-specific and gender-sensitive policies, enhancing preparedness, and strengthening health systems in East Asia to respond to the increasing burden of multiple sclerosis.",

It has long been used to activate blood circulation and remove blood stasis for the treatment of ischemic stroke. Modern pharmacological research has verified its potent anticoagulant and anti-inflammatory activities. Current studies mainly focus on its polypeptide components that exert antithrombotic effects to improve cerebral ischemia, while the neuroprotective potential and related mechanisms of its small-molecule constituents remain largely unclear. This study aimed to investigate the therapeutic effects of the ethyl acetate extract (EA) of P. manillensis on cerebral ischemia-reperfusion injury and to clarify its underlying molecular mechanism. The chemical constituents of EA were identified by UPLC-Q-TOF-MS/MS. Network pharmacology and molecular docking were used to predict and verify core targets and pathways. Neuroprotective and anti-inflammatory effects of EA were evaluated in a rat MCAO/R model, OGD/R-injured SH-SY5Y cells, and LPS-stimulated BV2 cells, using histological staining, Western blot, immunohistochemistry, and RT-qPCR. Seven small-molecule components were identified in EA, and 314 overlapping targets related to ischemic stroke were screened. Network analysis showed that TLR4 was the core target, and the main enriched pathways included NF-\u03baB, Toll-like receptor, apoptosis and TNF signaling pathways. Consistent with the predicted results, EA significantly reduced cerebral infarct volume and improved neurological deficits in MCAO/R rats, and inhibited neuronal apoptosis and microglial inflammation in vivo. In vitro, EA notably improved the survival of OGD/R-injured neurons and suppressed LPS-induced inflammatory responses in BV2 cells. Meanwhile, EA markedly downregulated the expression of TLR4/NF-\u03baB and NLRP3 inflammasome-related molecules. The present study demonstrated that EA protects against cerebral ischemia-reperfusion injury by inhibiting neuronal apoptosis and TLR4/NF-\u03baB-mediated neuroinflammation. These findings provide a scientific basis for the traditional clinical application of P. manillensis and suggest that EA could serve as a potential therapeutic candidate for ischemic stroke.",

Unilateral recurrent laryngeal nerve\uff08RLN\uff09 injury rabbit models (n\u00a0=\u00a012) were established. At 2, 4, 8, and 12 weeks post-injury, RLN and neuromuscular junction\u00a0regeneration were evaluated via transmission electron microscopy\u00a0and immunofluorescence. Thyroarytenoid\u00a0muscle histopathology was assessed by hematoxylin and eosin\u00a0staining, and vocal fold (VF) movement was quantified via laryngoscopy. Correlation between neuroelectrophysiological changes and VF motion was analyzed in eight patients with RLN electrocautery injuries. At 2 weeks, myelin sheaths and synaptic membranes showed extensive disintegration. The single muscle fiber diameter (SMFD) decreased to 56.16%, the muscle fiber area ratio (MFAR) decreased to 40.35%, and the motion range ratio (MRR) decreased to 12.2%. At 4 weeks, the myelin lamellae continued to disintegrate with a small amount of regeneration. Regeneration of the presynaptic membrane (more than the postsynaptic membrane) began. MFAR was 46.86%, and MRR was 77.9%. At 8 weeks, the density of myelinated axon (DMA) peaked, but the axons and myelin sheath remained thin and immature. Postsynaptic membrane regeneration was significant, with partial overlap by the presynaptic membrane. MFAR rose to 58.59%, and MRR recovered to 96.9%. At 12 weeks, myelin sheaths thickened and matured despite a drop in DMA. Synaptic membrane number and morphology were normalized. SMFD and MFAR neared normal levels at 94.52% and 91.57%, respectively, and MRR recovered fully. 77.8% of patients exhibited partial or complete VF movement recovery.

A rapidly accumulating body of evidence has not simply challenged the long-dominant monoamine deficiency hypothesis but has provided a mechanistic framework that may explain many of the observed monoaminergic alterations in depressive cohorts, including IDO1-driven serotonin depletion, cytokine-mediated AMPA receptor internalization, and HPA-immune feedback dysregulation. Neuroinflammation, particularly glial activation across microglial, astrocytic, and oligodendrocyte lineages, and its downstream consequences for tryptophan metabolism, glutamatergic transmission, synaptic plasticity, and neurotrophic signaling, represents a central pathophysiological mechanism in a substantial subgroup of depressed patients. Peripheral inflammatory markers, including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha, are elevated in a significant proportion of individuals with major depressive disorder, and these elevations predict poor response to conventional antidepressants while identifying patients who may respond preferentially to anti-inflammatory strategies. Post-mortem studies, positron emission tomography imaging of translocator protein density, and transcriptomic analyses of brain tissue have collectively provided consistent, though not yet fully definitive, evidence that microglial activation is a neurobiological feature of depression rather than a consequence of comorbid physical illness. This review synthesizes current mechanistic understanding of the neuroinflammatory hypothesis of depression, examines the evidence base from epidemiological, biomarker, neuroimaging, and interventional studies, including null findings and methodological limitations, evaluates emerging therapeutic strategies targeting the immune-brain interface, and identifies the critical questions that will determine whether immunopsychiatry fulfills its promise as a precision medicine framework for treatment-resistant depression.",

A retrospective analysis was conducted on adult-onset MOG-ON patients diagnosed in the Ophthalmology Department of the Chinese People's Liberation Army General Hospital (PLAGH) from January 2019 to January 2024. Patients were divided into two groups based on their experience of a relapse course: the relapsing group and the monophasic group. Multivariate analysis was performed to examine the effects of various clinical factors on the risk of recurrence. Among 126 screened participants, 56 were excluded. A total of 70 patients (median [IQR] age at onset, 35.50 [30.00, 48.75] years; 46 females [65.71%]) were included. During a median follow-up of 31.50 (IQR 21.25-52.75) months, disease relapse occurred in 54.29% (38/70) of patients. Multivariate analysis revealed that being female significantly elevated recurrence risk (hazard ratio [HR] 3.92, 95% CI 1.63-9.42, p\u2009=\u20090.002), while administration of immunosuppressive maintenance therapy after the first episode was associated with a lower likelihood of recurrence (HR 0.30, 95% CI 0.10-0.87, p\u2009=\u20090.026).

We sought to build a cross-disease, multi-region, quantitative map of CSF1R-positive microglia in neurodegenerative conditions and progressive multiple sclerosis (MS) lesions, with an exploratory comparison to presynaptic marker burden. CSF1R mRNA\u2011positive microglia were quantified by RNAscope across six cortical regions (MFG, IFG, ITG, AG, CA1, EC) in early\u2011onset Alzheimer's disease (EOAD), late\u2011onset AD (LOAD), progressive supranuclear palsy (PSP), and frontotemporal lobar degeneration with TDP-43 inclusions due to progranulin mutation (FTLD\u2011GRN), and in primary and secondary progressive MS (PPMS, SPMS) within cortical gray\u2011matter plaques, plaque-adjacent gray matter and white matter. Positivity was defined a priori as\u2009\u2265\u20093 puncta with housekeeping\u2011probe pass and negative\u2011control verification, counting blinded, and densities were cortical\u2011thickness corrected. Iba-1 immunolabeling verified microglial identity. Western blot provided protein\u2011level verification. We explored ROI\u2011level associations of CSF1R with SV2A and synaptophysin previously measured in the same regions/cases. In neurodegeneration, increases were smaller and region\u2011specific (e.g., EOAD-ITG/CA1; LOAD-AG; PSP-AG; FTLD\u2011GRN-IFG/ITG/AG/EC), with minimal white\u2011matter change. In progressive MS, gray-matter CSF1R-positive microglia densities did not differ from controls, whereas SPMS white matter was increased. Exploratory analysis showed that CSF1R and SV2A were positively associated across ROIs in neurodegenerative diseases (e.g., PSP approximately \u03c1\u2009=\u20090.66), and weakest in LOAD; synaptophysin showed similar patterns, suggesting that regions with higher CSF1R-positive microglia density can coincide with relative preservation of presynaptic markers.

In this study, we investigated the effects of hUCB-MNCs treatment in a mouse model of VaD induced by bilateral common carotid artery stenosis (BCAS). Behavioral assessments showed that hUCB-MNCs treatment improved cognitive performance, affective-like behaviors, and motor coordination in BCAS mice. Histopathological analyses demonstrated that hUCB-MNCs treatment attenuated white matter injury, preserved myelin integrity, and mitigated neuronal and synaptic damage. Integrated transcriptomic and proteomic analyses of corpus callosum (CC) tissues revealed enrichment of immune-regulatory, phagocytosis-related, and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT)-associated pathways after hUCB-MNCs treatment. In vivo and in vitro analyses further indicated that hUCB-MNCs helped preserve microglial homeostatic features and improved myelin debris-handling responses. Collectively, these findings suggest that hUCB-MNCs ameliorate VaD-associated pathology, at least in part, by modulating microglial myelin debris-handling responses and PI3K/AKT-related signaling, highlighting hUCB-MNCs as a promising cell-based therapeutic candidate for VaD.",
"42400090": "ID: 42400090\nTitle: Study protocol: double-blind, randomized, prospective, placebo controlled parallel group phase II study to investigate the effect of glycerol phenylbutyrate (GPB) on neurofilament light chain (NfL) levels in patients with corticobasal syndrome (CBS).\nAbstract: Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disorder, with no disease-modifying treatments currently available. The most common underlying pathology is a 4-repeat tauopathy. Neurofilament light chain (NfL) is a biomarker of neuronal damage and has shown potential as a measure of disease progression. Glycerol phenylbutyrate (GPB), a prodrug of phenylbutyric acid, has demonstrated potential neuroprotective properties in preclinical studies on tauopathies. This phase II clinical trial will investigate the effects of GPB on NfL levels in CBS patients. The primary objective is to assess the efficacy of GPB in reducing NfL levels over 26\u00a0weeks compared to placebo as well as safety and tolerability of GPB. Secondary objectives include evaluating changes in clinical scales. This is an investigator-initiated double-blind, randomized, placebo-controlled, parallel-group phase II clinical trial, performed in two German university hospitals. A total of 32 patients with CBS will be enrolled and randomized to receive either GPB or placebo. The primary outcome is the change in NfL levels between baseline and 26\u00a0weeks as well as safety and tolerability of GPB. Secondary outcomes are changes in clinical scores. Exploratory analyses involve pharmacokinetics, changes in the metabolomic, proteomic and lipidomic profiles and imaging outcomes, such as MRI and microglia-PET. The study protocol has been approved by the lead ethics committee at LMU Munich and conforms to the ethical principles outlined in the Declaration of Helsinki and Good Clinical Practice (GCP) guidelines. If successful, this clinical trial could identify a novel therapeutic approach for slowing disease progression in CBS, contributing to a broader understanding of GPB's therapeutic potential. The clinical trial has been registered in ClinicalTrials.gov (NCT05983588) and due to Transition in the Clinical Trials Information System (CTIS; EUCT No. 2024-516897-31-00, date of transition: 2024-09-26).",

In this multicenter retrospective study (January 2020-June 2025), we screened 327 neuro-ophthalmic patients from a bio-repository of 2,321 ICI-treated individuals, identifying 88 patients with CBON across 3 independent cohorts (n\u2009=\u200925, 29, and 34). Longitudinal serum samples (pre-ICI, prodromal, onset, and follow-up) were available for 12 patients. A matched control group of 49 ICI-treated patients without neuro-ophthalmic symptoms was included. Serum samples were analyzed using cell-based assays for 25 neural-specific IgG autoantibodies. Longitudinal samples were assessed for antibody dynamics. Correlations between serostatus and clinical features were evaluated. Autoantibody profiling revealed a highly focused immune response concentrated against aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG). Seropositivity rates for these antibodies ranged from 17.3% to 32.4% across cohorts, whereas other neural antibodies were detected at markedly lower frequencies (<12%). Longitudinal analysis demonstrated a clear seroconversion pattern, with antibodies undetectable at pre-ICI baseline but emerging at symptom onset, which remained detectable during follow-up in a subset of patients. These AQP4/MOG antibodies were virtually absent in control patients (0-2%). This study establishes AQP4 and MOG as the dominant autoantibodies in CBON, providing a serological framework for diagnosis and classification. The persistent antibody response following ICI-induced seroconversion offers direction for future mechanistic investigations. ANN NEUROL 2026.",

Building on foundational work demonstrating motor learning-induced neuroplasticity, we highlight growing recognition that myelination remains adaptable across the lifespan and may be harnessed to support motor relearning, neuroprotection, and remyelination in MS. Preclinical and human studies demonstrate that neuronal activity, especially that induced by motor learning, regulates oligodendrocyte behavior and myelin remodeling. Rodent models show that skilled training enhances oligodendrocyte precursor cell proliferation and myelin thickness, while human neuroimaging confirms training-related increases in myelin-sensitive metrics within task-relevant systems. In MS, early evidence from exercise and motor training studies suggests task-specific white matter plasticity, though sample sizes remain small and imaging outcomes heterogeneous. Additional work points to synergistic potential between behavioral training, neuromodulation, and pharmacologic remyelinating agents. Notably, the combination of exercise and clemastine produces robust remyelination in preclinical models. With MS patients now living longer, aging introduces additional vulnerabilities-including inflammation, microglial dysfunction, and reduced regenerative capacity-but myelin retains responsiveness to behavioral and environmental enrichment. Experience-dependent myelin plasticity represents a promising but underexplored mechanism for enhancing neurorehabilitation outcomes. Motor learning, physical exercise, and multimodal interventions may support adaptive myelination, though optimized dosing, timing, and biomarkers remain undefined. Future research should employ targeted, multimodal imaging approaches and integrate behavioral, neuromodulatory, and pharmacologic strategies, in addition to following patients longitudinally post-intervention, to clarify the therapeutic potential of activity-driven remyelination.",
"42401006": "ID: 42401006\nTitle: Spinal cord microglia exhibit a dysfunctional response to myelin damage.\nAbstract: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that affects both the brain and spinal cord, although the brain has historically received greater attention. In the inducible, oligodendrocyte-specific knockout model of Myrf, which results in white matter damage to both the brain and spinal cord, our laboratory previously demonstrated that the brain undergoes remyelination following white matter damage, whereas the spinal cord has limited remyelination. We also observed that brain microglia display a much stronger activation than spinal cord microglia. Microglia regulate remyelination by clearing myelin debris, processing resulting lipids, and modulating the inflammation response. Therefore, we hypothesized that microglia are involved in limiting spinal cord remyelination in this model, either by having a limited phagocytosis response or by causing neuroinflammation. To test our hypothesis, we characterized microglial phenotypes during demyelination in both brain and spinal cord in the Myrf demyelination model. The brain exhibited an earlier microglial activation response and showed a higher percentage of microglia expressing phagocytic markers, suggesting a primed state for responding to damage. In contrast, spinal cord microglia showed a delayed increase in cells expressing phagocytic markers, sustained inflammation, and a predominately ameboid morphology during demyelination. Together, these findings in the Myrf demyelination model indicate that brain microglia mount a timely and coordinated response to demyelination that supports remyelination, whereas spinal cord microglia adopt a dysfunctional phenotype that likely contributes to reduced myelin repair.",

These manifestations partially resemble motor dysfunction in multiple sclerosis. Panax quinquefolius Saponins (PQS), are major bioactive constituents, but their effects on demyelination and related molecular changes remains unclear. To investigate the effects of PQS on demyelination and explore associated changes in inflammatory signaling and lipid metabolism. PQS was qualitatively profiled by UPLC-QTOF-MS and quantitatively standardized by HPLC-DAD. Male C57BL/6N mice were randomly divided into six groups (n = 12-16/ group): Control, Model (daily intragastric administration of 330 mg/kg of cuprizone for 6 weeks), Positive control (10 mg/kg of Clemastine), and low-, medium-, and high-dose PQS groups (25, 50, or 100 mg/kg). During week 2-6, mice received drugs by daily intragastric administration. Behavioral assessments including pole test, rotarod, and open field test were performed. Myelin integrity and related molecular changes were evaluated by histological staining, immunofluorescence, transcriptomics, Western blotting, and molecular docking. PQS ameliorated CPZ-induced motor dysfunction in behavioral assessments (P < 0.05). PQS also attenuated myelin loss in the corpus callosum, with the high-dose group increasing myelinated areas to approximately 74% of control levels (P < 0.01). Transcriptomic and protein analyses showed that PQS downregulated JAK1/STAT3/NLRP3 inflammatory pathway. In parallel, the HMGCS1-NPC1-MAL axis was upregulated, accompanied by increased mevalonate and total cholesterol levels (P < 0.05) and reduced PLIN2 expression (P < 0.001), suggesting decreased lipid droplet accumulation and altered cholesterol metabolism.Molecular docking predicted ginsenosides Rb3, Rk3, Re, Rc, Ro, and Rf may interact with targets related to inflammatory and lipid metabolism. PQS supported myelin restoration, which is correlated with a modulation of the JAK-STAT signaling pathway and HMGCS1/NPC1-associated lipid homeostasis. PQS may represent a potential therapeutic lead for demyelinating diseases, although mechanisms require further validation.",

The cGAS-STING pathway has been widely shown to regulate HK2 expression in macrophages, but whether it participated in SVPLA2-induced HK2 upregulation was unknown. Herein, we found that in RAW 264.7 macrophages, N. atra SVPLA2 triggered mitochondrial dysfunction and mtDNA release. Subsequently, SVPLA2 activated the cGAS-STING pathway. Gene silencing of STING using siRNA abrogated SVPLA2-induced HK2 upregulation and suppressed M1 polarization. Taken together, this study revealed the cGAS-STING-HK2 axis as an important upstream mechanism underlying N. atra SVPLA2-induced metabolic reprogramming of macrophages, providing new insights into the pathogenic mechanisms of snake venom.",

However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17\u202fA+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.",

Male C57BL/6J mice were exposed to 21\u202fdays of wet bedding stress followed by a poly I:C injection. Post viral fatigue syndrome (PVFS)-like symptoms were evaluated over 7\u202fdays post-injection using grip strength testing, the forced swim test, von Frey filament testing, the Morris water maze, the open field test, and the social interaction test. Body temperature and locomotor activity were continuously monitored via intraperitoneally implanted dataloggers. Serum concentrations of interleukin-6 (IL-6), IL-10, and C-X-C motif chemokine ligand 10 (CXCL10) were quantified. In separate cohorts, minocycline (a microglial activation inhibitor) or RU486 (a glucocorticoid receptor antagonist) was administered prior to poly I:C injection. Following IP injection of poly I:C, body temperatures in both stressed and unstressed mice were significantly elevated, indicating a polyphasic febrile response. At 7\u202fdays post-injection, stressed mice treated with poly I:C exhibited persistent fatigue, mechanical allodynia, depressive-like behavior, impaired spatial memory, increased anxiety-like behavior, and reduced social interaction. Serum levels of IL-6 and CXCL10 remained elevated and correlated with behavioral outcomes. Pretreatment with minocycline partially attenuated both the behavioral and immune responses, whereas RU486 pretreatment did not. These findings demonstrate that TLR3-mediated systemic inflammation induced by poly I:C produces persistent, multi-domain PVFS-like symptoms in chronically stressed mice. The attenuation by minocycline implicates neuroinflammation as a possible mechanism.",

To address this, cultures of the main glial cell types in the central nervous system (CNS), including astrocytes, microglia, oligodendrocyte progenitors, and differentiating oligodendrocytes, were created to examine the impact of an in vitro hypoxia-ischemia (HI) model on autophagy. The HI insult was mimicked by applying temporal oxygen-glucose deprivation (OGD). Since neonatal hypoxic-ischemic insults primarily affect the brain's white matter, the study predominantly focused on oligodendrocytes at different stages of maturation: progenitor cells versus cells that express myelin components (e.g. MBP). The results show that the different glial fractions exhibit varying sensitivity to the applied conditions. Maturing oligodendrocytes were found to be more sensitive to OGD conditions than the progenitor fraction. The OGD procedure was proven to impact the expression of autophagy markers, indicating the activity of this process in response to injury. Western blot analysis of oligodendrocyte progenitor cells (OPCs) showed that the autophagy substrate marker p62 increased after six hours, which may suggest transient inhibition and subsequent activation of autophagy. To verify the involvement of autophagy in the differentiation of neonatal oligodendrocytes, the process was modulated using chloroquine (CQ) treatment. CQ is recognised as an inhibitor of autophagic flux because it disrupts lysosomal acidity and prevents the breakdown of autophagosomes. CQ treatment resulted in the accumulation of autophagosomes. The results suggest that abnormalities in the functioning of glial cells, particularly oligodendrocytes, in response to hypoxic-ischaemic (HI)-like conditions might be associated with altered autophagic flux in response to cellular stress. Transient alterations in autophagy were observed within 24\u00a0h of limiting oxygen and glucose supply, and these alterations may contribute to subsequent disorders in oligodendrocyte differentiation. This is recognised as one of the major issues in the pathogenesis of neonatal hypoxia-induced damage. Therefore, modulation of autophagy could be a promising therapeutic approach to prevent these adverse changes.",

These pathophysiological changes may profoundly affect the pharmacokinetics of fentanyl, an opioid widely used for analgesia in trauma care. Previous studies, predominantly based on fixed-pressure shock models, may not adequately reflect clinically relevant hemodynamic conditions. Therefore, we employed a fixed-volume HS model as an alternative approach to reflect hypovolemia-associated perfusion deficits influencing fentanyl disposition. This study aimed to evaluate the pharmacokinetics of fentanyl and its primary metabolite, norfentanyl, in an experimental model of fixed-volume HS. Male Wistar rats were randomly divided into two groups: a control group (C; n\u00a0=\u00a06) and a fixed-volume hemorrhagic shock group (HS; n\u00a0=\u00a06). In the HS group, hemorrhage was induced by withdrawal of 30% of the estimated blood volume (EBV) following vascular cannulation. Fentanyl (10\u00a0\u00b5g/kg) was administered intravenously, and serial blood samples were collected over 60\u00a0min. The concentrations of plasma fentanyl and norfentanyl were determined by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Pharmacokinetic parameters were calculated using Phoenix WinNonlin software. Non-compartmental analysis demonstrated significantly increased systemic exposure to fentanyl in the HS group, reflected by higher area under the concentration-time curve (AUC0-\u221e and AUC0-t) values, accompanied by a marked reduction in systemic clearance (CL). Mean residence time (MRT) and terminal elimination half-life (t\u00bd\u03bbz) were significantly prolonged. Compartmental analysis confirmed a more than two-fold increase in fentanyl exposure, driven primarily by reduced clearance and prolonged elimination. In contrast, peak plasma concentrations (Cmax) showed only a borderline increase, and no statistically significant differences were detected in distribution-related parameters. These findings suggest that the major detectable pharmacokinetic changes associated with HS were primarily related to impaired fentanyl elimination. The metabolic conversion ratio (MCR), defined as the ratio of norfentanyl\u00a0AUC0-t to fentanyl\u00a0AUC0-t, was lower in the HS group (0.117) compared with controls (0.197). HS significantly alters fentanyl pharmacokinetics in rats by reducing clearance and increasing systemic exposure. The lower norfentanyl-to-fentanyl AUC0-t ratio suggests that HS may also affect metabolite formation or disposition.",

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

Notably, microstructural WM alterations, detectable early via advanced neuroimaging techniques such as diffusion tensor imaging, frequently precede overt gray matter atrophy and cognitive decline, highlighting their potential as early contributors to AD pathogenesis. The origins of WM pathology are multifactorial, involving a complex interplay among \u03b2-amyloid (A\u03b2) and tau aggregation, energy dysmetabolism, neuroinflammation, vascular dysfunction, and cellular senescence. Importantly, we emphasize a paradigm-shifting perspective: WM degeneration acts not merely as a downstream outcome but as a key driver of AD pathogenesis, capable of accelerating protein aggregation, amplifying neuroinflammation, and compromising neural plasticity. Given its early manifestation and close association with symptom onset, WM integrity has emerged as a sensitive and reliable biomarker for early AD detection and progression monitoring. Moving beyond diagnostics, the growing understanding of WM pathophysiology has unveiled a new frontier of therapeutic interventions aimed at myelin regeneration and WM protection. Despite persisting translational challenges, targeting WM integrity represents a pivotal avenue for developing disease-modifying therapies capable of slowing disease progression and improving clinical outcomes in patients with AD.",

This review analyzes the cellular and molecular mechanisms underlying alcohol neurotoxicity, integrating findings from animal models, human post-mortem studies, and neuroimaging investigations. Ethanol crosses the blood-brain barrier and generates toxic metabolites including acetaldehyde and reactive oxygen species, triggering oxidative stress, lipid peroxidation, and mitochondrial dysfunction. Chronic exposure induces glutamatergic and gamma-aminobutyric acid (GABA)ergic adaptations leading to excitotoxicity during withdrawal. Cell death occurs through apoptotic, necrotic, and necroptotic pathways, while microglial and astrocytic activation perpetuates neuroinflammation. Histopathological (HP) changes include selective neuronal loss in the prefrontal cortex, hippocampus, and cerebellum, dendritic simplification, and synaptic alterations. White matter pathology manifests as demyelination and axonal degeneration. Associated thiamine deficiency produces characteristic lesions in the mammillary bodies, thalamus, and cerebellar vermis. Neuroimaging techniques provide valuable HP correlates and biomarkers for disease monitoring. While some changes demonstrate partial reversibility with abstinence through remyelination and synaptic plasticity, extensive neuronal loss remains irreversible. Understanding these mechanisms is essential for developing neuroprotective therapeutic strategies.",

We investigated whether ferroptosis contributes to acute ischemic stroke using a transient middle cerebral artery occlusion model in pial collateral-deficient CB-17/Icr-+/+Jcl mice. Mice were subjected to 90\u2009min of ischemia followed by reperfusion, and the effects of the ferroptosis inhibitor UAMC-3203 on infarct evolution and post-stroke histological changes were examined. UAMC-3203 increased the survival of CD13-positive pericytes within infarct areas and enhanced infarct reduction in the subacute phase. In vitro, the glutathione peroxidase 4 inhibitor RAS-selective lethal 3 (RSL3) induced dose-dependent cell death in pericytes but not in endothelial cells, which was suppressed by UAMC-3203 but not by inhibitors of apoptosis or necroptosis. RSL3 induced lipid peroxidation in pericytes, as evidenced by malondialdehyde accumulation. Extracellular ferrous iron (Fe2+), but not ferric iron (Fe3+) or transferrin, caused intracellular Fe2+ accumulation and cell death in pericytes, which was further enhanced by oxygen-glucose deprivation with reperfusion and suppressed by UAMC-3203. Myelin debris containing abundant Fe2+ induced ferroptosis in cultured pericytes. These findings indicate that pericytes are a major ferroptosis-vulnerable cell type during ischemia-reperfusion and may represent a therapeutic target in acute ischemic stroke.",

The hallmarks of the disease are amyloid plaque accumulation, microglia and astrocyte activation, and loss of presynaptic structure leading to cognitive decline. Recently, oligodendrocyte (OL) and myelin abnormalities have emerged as important contributors to the pathogenesis of AD. In normal brain homeostatic conditions, OL maintain neuronal health through myelin axon interactions and by supplying neurotrophic and metabolic support. How strengthening OL function may support neuronal health in AD neurodegeneration remains to be fully characterized and represents a gap in knowledge and a missed therapeutic opportunity. This study sought to examine how myelin and OL may improve neuronal deficits associated with AD. We have generated a novel mouse model (AD/cKO) by crossing the AppNL-G-F mouse, an established AD model, which carries three human AD mutations in the mouse App gene, with the FusOLcKO whose OL depleted of Fus (Fused in Sarcoma) produce thicker myelin associated with greater cholesterol biosynthesis. We evaluated spatial memory function with standardized cognitive testing. We evaluated microglia density and state, astrocytic activation and toxic phenotype, myelin density, cholesterol content, amyloid plaque burden, presynaptic structures, and neuronal hypoxic and oxidative damage in the hippocampus and cortex. We characterized the transcriptome of AD/cKO hippocampal OL compared to AD by using single-cell transcriptomic studies. Spatial working memory was fully preserved in the aged AD/cKO mouse relative to the AD mouse. This outcome was associated with reduced neuronal oxidative damage, preserved presynaptic structures at the amyloid plaque niches, and a shift in microglia state at the niches in both hippocampus and cortex. In contrast, amyloid plaque burden and microglia density were decreased in the hippocampus but not in cortex, uncoupling the neuronal and microglia effects from the amyloid burden. Fus dependent myelin increase was present in both hippocampus and cortex. Single-cell transcriptomics of AD/cKO hippocampal OL revealed upregulation of energy metabolism and antioxidant genes, suggesting a role of OL enhanced energy metabolism in mediating protection of neurons and affecting microglia state in AD pathology. This work provides new insight into how oligodendrocytes may protect neurons in AD, communicate with other glial cellular players, and point to potential targets for disease intervention aimed at slowing AD progression.",

Tangeretin, a polymethoxylated citrus flavonoid, has neuroactive and anti-inflammatory properties. We investigated whether tangeretin protects against sepsis-associated neurocognitive deficits and delineated the underlying mechanisms, focusing on Akt signalling and microglial metabolism. Sepsis was induced by caecal ligation and puncture in mice. Tangeretin (15 or 30\u2009mg\u00b7kg-1\u00b7day-1, intraperitoneal) was initiated immediately after surgery and maintained throughout the study. Cognitive function was assessed by Morris water maze and novel object recognition. Hippocampal microglial activation and neuroinflammation were quantified. In vitro, BV2 cells and primary microglia were exposed to lipopolysaccharide (LPS, 1\u00a0\u03bcg\u00b7ml-1) with/without tangeretin (40\u2009\u03bcM) to measure cytokine production, migration and Akt activity. Direct tangeretin-Akt interaction was tested by surface plasmon resonance and cellular thermal shift assay. Metabolic readouts focused on glycolysis. Tangeretin improved sepsis-induced cognitive deficits, decreased hippocampal microglial activation, and lowered proinflammatory cytokine levels and microglial migration. It exerted anti-inflammatory effects via inhibition of the Akt pathway, and pharmacological Akt activation blocked these effects. Surface plasmon resonance and cellular thermal shift assay showed hat tangeretin binds Akt. Metabolically, tangeretin reduced LPS-induced glycolysis (decreased extracellular acidification rate and glycolytic capacity), consistent with diminished Akt phosphorylation and microglial activation. Tangeretin mitigates sepsis-associated neuroinflammation and cognitive impairment by targeting microglial Akt signalling and restraining glycolytic reprogramming. These data support tangeretin as a mechanistically informed candidate for adjunctive therapy in sepsis-related neurocognitive dysfunction.",
"42403363": "ID: 42403363\nTitle: Roles of Microglia in Cerebral Small Vessel Disease.\nAbstract: Cerebral small vessel disease (CSVD) is a major cause of vascular dementia, characterized by heterogeneous pathologies affecting the brain's microvasculature. In recent years, researchers have recognized the significant role of neuroinflammation and increased permeability of the blood-brain barrier (BBB) in the development of CSVD. Within this framework, microglia exert multifaceted roles. This review synthesizes current evidence on microglial involvement in CSVD, covering their heterogeneity, associations with neuroimaging markers, pathogenic mechanisms, and the translational prospects of microglia-directed therapies. Chronic cerebral hypoperfusion drives microglial activation toward pro-inflammatory phenotypes, triggering oxidative stress, inflammatory mediator release, and BBB disruption. These pathological changes correlate spatially with white matter hyperintensities, enlarged perivascular spaces, and lacunes. Microglia also interact with other glial cells to modulate disease progression. Preclinical studies have shown that modulating microglial phenotypes can be beneficial, though clinical translation remains challenging. Microglia serve as pivotal double-edged players, central to both neuroinflammation and BBB dysfunction in CSVD.Understanding the intricate relationship between microglia and CSVD is essential for elucidating the underlying mechanisms and paves the way for novel therapeutic approaches.",

Whether the 1 MAC (minimum alveolar concentration) dose of isoflurane (1.2%) and other commonly used volatile anesthetics such as sevoflurane (2%), and desflurane (6%), support peripheral nerve regeneration is not known. The aim of the current study is to examine these possibilities in a rodent sciatic nerve injury model. Twelve-week-old male Lewis rats underwent sciatic nerve cut and repair and were divided into following groups. (1) control (no treatment), (2) isoflurane (1.2%), (3) sevoflurane (2%), and (4) desflurane (6%). Volatile anesthetic conditioning was achieved by administering isoflurane, sevoflurane, and desflurane for 1 h, beginning 1-h post sciatic nerve cut and repair, and the anesthetic exposure was repeated for the next two consecutive days for 1 h. Functional outcomes such as compound muscle action potential (CMAP), evoked muscle force (tetanic and specific tetanic force), wet muscle mass, and axonal counts were measured at 12 weeks post-surgery. A significant increase in the axonal numbers and myelin width was observed in the desflurane group. This was associated with the improvement in the specific tetanic force measured at 12 weeks post-surgery. Desflurane promoted axonal regeneration and myelination at 12 weeks post-peripheral nerve injury and repair in a murine model. Future experiments focusing on identifying the optimal dose to improve functional outcomes, and the molecular mechanisms underlying desflurane's potential protective effect are warranted.",
"42404111": "ID: 42404111\nTitle: Didymin mitigates neuroinflammation and preserves blood-brain barrier integrity after subarachnoid hemorrhage.\nAbstract: Subarachnoid hemorrhage (SAH) is a highly lethal and disabling type of stroke. The main causes of poor prognosis are neuroinflammation, blood-brain barrier (BBB) disruption and brain edema following hemorrhage. Didymin has shown neuroprotective effects in intracerebral hemorrhage; however, its regulatory role in SAH remains unclear. The rat SAH model was established using the internal carotid artery puncture method, while an in vitro model was developed by stimulating human brain microvascular endothelial cells (HBMECs) with hemoglobin (Hb). Following didymin treatment, neurological functional outcomes were assessed using the modified Garcia score and the balance beam test. Nissl staining was performed to evaluate neuronal pathological changes. Immunofluorescence staining was employed to assess microglial activation and BBB integrity. Brain water content was measured to evaluate the severity of cerebral edema. Western blot analysis was utilized to detect the expression of matrix metalloproteinase 9 (MMP9), apoptosis-related proteins (Bcl-XL, Bcl-2, Bax), pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and tight junction proteins (ZO-1, Occludin). Didymin treatment significantly improved neurological function scores in SAH rats by alleviating neuronal damage and apoptosis. On one hand, didymin reduced post-SAH neuroinflammation by inhibiting excessive microglial activation and the expression of pro-inflammatory cytokines. On the other hand, didymin preserved BBB integrity and alleviated brain edema by downregulating MMP9 expression. In Hb-induced cell model, didymin suppressed MMP9 expression and promoted the expression of tight junction proteins. In this study, we demonstrated that didymin mitigates neuronal damage and apoptosis following SAH, effectively suppresses neuroinflammation, maintains the integrity of the BBB, and attenuates brain edema. These findings suggest that didymin holds promise as a potential therapeutic candidate for the treatment of SAH.",

It is characterized by persistent numbness and burning pain extending from the affected axilla to the medial aspect of the upper arm, as well as restricted shoulder joint mobility, which severely impacts postoperative recovery and quality of life. Current interventions primarily focus on symptomatic analgesia and functional exercises, lacking standardized external treatment protocols to promote nerve repair. Transcutaneous electrical acupoint stimulation (TEAS) combines the advantages of acupuncture and transcutaneous electrical stimulation. It is non-invasive and has high patient acceptance. Preliminary studies suggest it can promote axonal regeneration and myelin formation, yet scientific evidence-based evidence for ICBN syndrome is lacking. This study aims to systematically evaluate the therapeutic effects and safety of TEAS on ICBN syndrome through a prospective, randomized, sham-controlled trial, providing evidence-based medical evidence for clinical practice. This prospective, randomized, sham-controlled clinical trial will be conducted at the Yunnan Provincial Hospital of Traditional Chinese Medicine. We plan to recruit 200 patients with ICBN syndrome after breast cancer surgery. Participants will be randomly assigned in a 1:1 ratio to either the TEAS group or the Sham TEAS group, with 100 cases in each group. Both groups will start receiving treatment on the first postoperative day, administered once every other day. Ten sessions will constitute one course, for a total of three courses. The primary outcome measure is CMS. Secondary outcome measures include MMT, EMG, VAS, SWMT, FACT-B, SF-36, and TCM-SD. Adverse events will be recorded throughout the study. https://itmctr.ccebtcm.org.cn/mgt/project/view/2041939715654978881, identifier, ITMCTR2024000864.",

However, in Alzheimer's disease and related dementias, chronically pro-inflammatory microglia may contribute to pathology. We hypothesized that inflammatory alterations, measured as microglia density via 18\u2005kDa translocator PET, would be elevated with a topography similar to tau, be most strongly associated with tau compared to amyloid and neurodegeneration, and mediate pathways among amyloid, tau and neurodegeneration. Participants (21 cognitively unimpaired, 25 cognitively impaired) from the Longitudinal Imaging of Microglial Activation in Different Clinical Variants of Alzheimer's Disease study underwent baseline amyloid PET (Florbetaben standard uptake value ratio), tau PET (MK6240 standard uptake value ratio), 18\u2005kDa translocator PET (ER176 standard uptake value ratio) and structural MRI (grey matter volume). Biomarkers were quantified in 13 a priori regions of interest. Cognitive assessments and consensus diagnoses were performed at the Columbia Alzheimer's Disease Research Center with biomarker information when available to define cognitive impairment. We evaluated cross-sectional regional colocalization of microglia density and amyloid, tau and neurodegeneration biomarker elevations in cognitively impaired individuals compared to amyloid-negative cognitively unimpaired individuals, microglia density associations with amyloid, tau and neurodegeneration biomarkers and microglia density mediation pathways among amyloid, tau and neurodegeneration. Exploratory analyses were stratified by amyloid positivity. Across all cognitively impaired individuals with different underlying brain microenvironments to which microglia are sensitive, higher microglia density colocalized with greater tau (10 regions) more often than with amyloid (8 regions) and neurodegeneration (4 regions), was associated with greater tau (\u03b2 = 0.29-0.67 in cingulate, lingual and parietal regions) and neurodegeneration (\u03b2 = -3.6 to -0.14 in limbic and medial temporal regions), and mediated tau-associated neurodegeneration (\u03b2 = -0.44 to -0.26 in limbic, temporal and parietal regions). In the context of amyloid-positivity, microglia may also mediate amyloid-associated tau (\u03b2 = 0.24-0.25 in parietal regions) and tau spreading (\u03b2 = 0.09-0.12 across progressive Braak stage regions), whereas amyloid may not be necessary for tau-associated neurodegeneration, particularly in limbic regions (\u03b2 = -0.46 to -0.37 in amyloid-negative individuals with cognitive impairment alone). Glia may represent a promising target for intervening on tau-associated neurodegeneration across individuals with cognitive impairment.",

While manganese ions (Mn) can activate the cGAS-STING pathway to potentiate innate immunity, their clinical application is limited by poor tumor accumulation and potential systemic toxicity. Alendronate (ALN), an FDA-approved agent, exerts T cell immunomodulatory activity but is hampered by low bioavailability and undesired bone targeting. To effectively potentiate antitumor immunity against CRC, we developed a manganese-alendronate (MnALN) nanomedicine via infinite coordination, leveraging Mn and ALN to synergistically eliminate tumor cells. In addition, Mn triggers reactive oxygen species (ROS)-mediated endoplasmic reticulum (ER) stress and subsequent immunogenic cell death (ICD) in tumor cells, while its combination with ALN further enhances T cell immune responses, ultimately achieving efficient tumor growth inhibition and intense anti-tumor immune response. This study presented a dual-functional MnALN nanomedicine synthesized from clinically available Mn and ALN, simultaneously activating apoptosis and inflammation-related pathways in CRC cells, which provides an effective strategy for immune tolerance CRC therapy.",

"42404802": "ID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.",
"42404887": "ID: 42404887\nTitle: Mechanisms and impact of long COVID: pathophysiology, neuropsychiatric effects and vaccination.\nAbstract: Long COVID or post-acute sequelae of COVID-19 is defined as an after-effect of acute COVID-19 infection. Its broad clinical symptoms include brain fog, shortness of breath, fatigue, joint, chest, or muscle pain, dysautonomia and neuropsychiatric symptoms such as anxiety, depression and post-traumatic stress disorder. It is estimated that 1 in every 5 COVID-19 survivors exhibit symptoms within the Long COVID bracket. An array of risk factors such as smoking habit, age, obesity, female sex, and prior hospitalization may increase the probability of a person developing Long COVID. While the underlying mechanisms of Long COVID remain elusive, we examine the various possible pathophysiologies involved in Long COVID. We take up impactful neuropsychiatric issues as another spectrum of Long COVID symptoms and the likely effect of various forms of COVID-19 vaccines. In this review, the focus will be on the main mechanisms associated with the development of long COVID, which include latent Epstein-Barr virus reactivation, molecular mimicry, virus persistence, autoantibodies, and mitochondrial dysfunction. Understanding these mechanisms shed light on the continued persistence of COVID-19 related symptoms long after the resolution of acute infection. For instance, the reactivation of Epstein-Barr virus in the immunocompromised context seen post-acute SARS-CoV-2 infection could lead to the symptoms commonly observed in Long COVID such as fatigue and brain fog. The Epstein-Barr virus could possibly disrupt mitochondrial function, explaining the fatigue commonly observed in Long COVID patients. Other factors such as continued presence of viral particles in specific areas such as the gut may result in continued inflammation, leading to manifestations such as fatigue, cognitive impairment and gastrointestinal dysfunction. Additionally, heightened and persistent presence of autoantibodies post-acute infection results in persistent symptoms and could potentially trigger the onset of autoimmune disorders. We also aim to revisit the diverse and prolonged effects of the COVID-19 pandemic that continue to affect the well-being and quality of human life.",

To investigate the efficacy and safety of rituximab administration during conditioning regimen following haploidentical hematopoietic stem cell transplantation(haplo-HSCT)in the prevention of post-transplant EBV infection. We conducted a retrospective analysis of 100 patients with acute leukemia or myelodysplastic syndrome who underwent haplo-HSCT. Patients in observation group(R group) received rituximab (375 mg/m\u00b2) on day -3 before transplantation due to the presence of donor-specific antibody (MFI \u2265 2000) (n = 25) and patients in control group (C group) did not receive rituximab (n = 75) and donor-specific antibody was low (MFI < 2000). The primary objectives were the incidence of EBV-DNA viremia and PTLD within one-year post-transplantation. Secondary objectives included the incidence of CMV infection, cumulative incidence of acute graft-versus-host disease (aGVHD) and chronic GVHD, 100-day non-relapse mortality (NRM), progression-free survival (PFS), and overall survival (OS). No significant differences were observed in baseline characteristics between the two groups except for primary disease. When compared with the C group, patients in R group exhibited a lower cumulative incidence of EBV viremia within one-year post - transplantation (4.00% vs. 22.67%, P\u00a0=\u00a00.049) and a lower incidence of aGVHD (28% vs. 50.67%, P\u00a0=\u00a00.048). There was a trend toward reduction of PTLD in the R group compared with C group (0% vs. 10.67%, P\u00a0=\u00a00.089).There were no significant differences of the incidence of CMV viremia (24% vs. 13.33%, P\u00a0=\u00a00.208), cGVHD (16% vs. 12%, P\u00a0=\u00a00.607), and 100 - day NRM (4.0% vs. 10.67%, P\u00a0=\u00a00.313) between two groups. The 2-year OS rates in the R group and C group were 83.8% \u00b1 0.086% and 81.9% \u00b1 0.050% respectively (P\u00a0=\u00a00.360). The 2-year PFS rates in the R group and C group were 83.8% \u00b1 0.086% and 72.6% \u00b1 0.068% respectively (P\u00a0=\u00a00.360). The combined use of rituximab during the conditioning regimen may be regarded as an effective strategy for preventing EBV reactivation after rATG - based haplo - HSCT in the era of letermovir for CMV prophylaxis.Prospective randomized controlled trials are still required to further validate the reliability of the results.",
"42404903": "ID: 42404903\nTitle: Cholinergic regulation of neuroinflammation: linking microglia, immunometabolism, and neuromodulation.\nAbstract: Neuroinflammation is increasingly recognized as a core pathological process in various neurological diseases, including neurodegenerative disorders, stroke, autoimmune demyelinating diseases, and acute brain dysfunction associated with systemic inflammation. Among its regulatory mechanisms, the cholinergic anti-inflammatory pathway links neural activity with immune regulation. However, its neurological relevance extends beyond the classical peripheral vagus nerve-mediated inflammatory reflex. Within the central nervous system, cholinergic signaling interacts with resident immune cells, particularly microglia, and influences inflammatory tone, neuronal vulnerability, and tissue repair. Recent advances in immunometabolism further suggest that metabolic reprogramming may bridge cholinergic signaling and microglial inflammatory phenotypes. In this review, we discuss the role of cholinergic regulation of neuroinflammation from three interrelated perspectives: microglia as the hub of core cells, immune metabolism as the basis of mechanism, and neural regulation as the frontier of transformation. We first reviewed the cholinergic system and its role in neuroimmune communication, then discussed how cholinergic signals shape microglial state and metabolic process, and finally evaluated its disease-specific evidence in Alzheimer's disease, Parkinson's disease, stroke, multiple sclerosis and acute inflammatory brain dysfunction. We will also discuss pharmacological and bioelectronic methods, including targeting cholinergic receptors and vagus nerve stimulation, as emerging therapeutic strategies. By integrating cholinergic biology, microglial heterogeneity, and metabolic reprogramming, this review proposes an updated framework for understanding neuroinflammation in neurology, and highlights the future opportunities for precise neuroimmune intervention.",

The aim of this work was to analyze healthy brain lifespan trajectories of paramagnetic and diamagnetic susceptibilities in deep gray matter (DGM) and white matter (WM) from a large database (339 subjects, 5 to 90\u2009years), all acquired at 3\u2009T on the same scanner, using \u03c7-separation and comparing it to two other common SSS methods (\u03c7-sepnet and APART-QSM). A 3D multiple echo gradient echo sequence was used to measure phase, R2* and QSM, as well as dual echo fast spin echo to measure R2. The mean value of WM and DGM regions was calculated for SSS output maps and plotted against age to evaluate trajectories across the lifespan. With \u03c7-separation, most DGM regions showed an increasing trend with age in the paramagnetic map, except for thalamus, which showed an inverted-U quadratic trajectory, and all DGM regions showed an increase in diamagnetic content with age. In WM, for the paramagnetic maps, body of corpus callosum, splenium and corticospinal tract showed an inverted quadratic trajectory, cingulum an increasing exponential, while no significant changes were seen in genu. For the diamagnetic WM maps, all regions followed a similar trajectory, increase in early life, peak around 40 to 60\u2009years, and decrease with age. The different SSS approaches yielded different curve shapes and mean values in many instances. For example, APART-QSM had consistently lower ppb values, \u03c7-sepnet had biologically unexpected results for early ages, and \u03c7-separation data had higher standard deviation of best-fit residuals when compared to the other evaluated methods for all analyzed regions and maps. All SSS methods enabled depiction of independent iron and myelin trends; however, different results between methods suggest caution in choosing SSS methods and the need for further methodological advances.",
"42406535": "ID: 42406535\nTitle: Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway.\nAbstract: Pyroptosis is an inflammatory type of programmed cell death that may contribute to epilepsy initiation and progression through neuroinflammation. Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.",

A pediatric patient with CAEBV-transformed ENKTL admitted to Nanshan Hospital Affiliated to Shenzhen University was retrospectively enrolled in this study, who received allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patient achieved complete remission after multiple cycles of preoperative chemotherapy. Triple probiotic preparations containing Bifidobacterium, Bacillus licheniformis, and Lactobacillus were administered throughout the preconditioning phase and post-transplant period. Persistent complete remission was achieved after transplantation with full donor chimerism of 100%. Long-term follow-up over 1 year post-transplantation showed no disease recurrence, EBV reactivation, severe infectious complications, or acute and chronic transplantation-related complications. This case study confirmed that allo-HSCT is safe and effective for the treatment of pediatric CAEBV-transformed ENKTL, with a significantly superior long-term prognosis compared with chemotherapy alone. Peri-transplant adjuvant application of microecological preparations may reduce the risks of respiratory tract infection and graft-versus-host disease in children. Given that this is a single-case study with limited follow-up duration, there are certain limitations in the clinical generalization of the conclusions.",
"42407186": "ID: 42407186\nTitle: Inhibition of toll-like receptor 4 by allicin suppresses mitochondrial DNA-mediated inflammation and pyroptosis to alleviate myocardial ischemia-reperfusion injury.\nAbstract: Mitochondrial DNA (mtDNA) leakage after myocardial ischemia/reperfusion (MI/R) injury activates inflammation and pyroptosis. Although toll-like receptor 4 (TLR4) is a known mediator of MI/R injury, its interplay with mtDNA remains unclear. This study investigates the cardioprotective mechanism of allicin, focusing on its disruption of the TLR4-mtDNA axis. This study aimed to clarify the mechanisms of inflammatory response and pyroptosis in MI/R injury and the therapeutic targets of allicin. The cardioprotective mechanism of allicin was investigated in both in vivo and in vitro MI/R models. In Sprague-Dawley rats, different concentrations of allicin were administered pre-reperfusion. Myocardial injury, cytosolic mtDNA leakage, and activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) and nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing 3 (NLRP3)-gasdermin D (GSDMD) pathways were assessed. Network pharmacology combined with molecular dynamics simulation identified TLR4 as a candidate signaling pathway for validation. In H9C2 cells subjected to OGD/R, the role of TLR4 in mtDNA-induced inflammatory response and pyroptosis, and the therapeutic mechanism of allicin, were studied using TLR4 agonist RS09 and inhibitor resatorvid. Myocardial injury markers, cytosolic mtDNA leakage, cGAS-STING and NLRP3-GSDMD pathway activity, and TLR4 expression were measured. In vivo experiments demonstrated that allicin alleviated MI/R injury, suppressed cytosolic mtDNA leakage, and inhibited the cGAS-STING-mediated inflammatory response and the NLRP3-mediated pyroptosis pathways. Subsequent network pharmacology and molecular dynamics simulation identified TLR4 as a potential mediator of these effects. In vitro studies revealed that TLR4 activation promotes mtDNA-dependent inflammation and pyroptosis, which were effectively suppressed by allicin or TLR4 inhibition. TLR4 activation aggravates MI/R injury by promoting mitochondrial damage and cytosolic mtDNA leakage, which activates the pro-inflammatory (cGAS-STING) and pro-pyroptotic (NLRP3-GSDMD) pathways. Allicin protects against MI/R injury by inhibiting TLR4 activation and the subsequent mtDNA-induced pathways, thereby reducing inflammation and pyroptosis."
