Неожиданное возрождение в отсутствие матричной металопротеины 7.

В множестве склерозов (MS) приток иммунных клеток в центральную нервную систему приводит к обезвоживанию мозга, зрительного нерва и спинного мозга. По мере того как MS прогрессирует, воспоминание становится все более неэффективным, что делает нейронные аксоны уязвимыми для дегенерации и приводит к постоянной неврологической инвалидности. При хронических поражениях MS аберрантная аккумуляция молекул внеклеточной матрицы (ECM), включая фибронектин и гиалуронан, ухудшает олигодендроцитную дифференциацию клеточных клеток, что ведет к сбоям в ремилинации. Таким образом, устранение ингибиторских УХМ

In multiple sclerosis (MS), an influx of immune cells into the central nervous system leads to focal demyelinating lesions in the brain, optic nerve, and spinal cord. As MS progresses, remyelination increasingly fails, leaving neuronal axons vulnerable to degeneration and resulting in permanent neurological disability. In chronic MS lesions, the aberrant acc…

Functional response to active and passive ankle movements with clinical correlations in patients with primary progressive multiple sclerosis.

Patients with multiple sclerosis (MS) activate a more diffuse cortical network than do healthy subjects when they perform motor tasks. This brain functional reorganisation might contribute to the limiting of disability, but it is unclear whether there is a loss of regional activation in more advanced disease. The aim of this study was to assess whether functional reorganisation diminishes in more disabled patients with primary progressive (PP) MS. The differences in the fMRI response to active and passive movements of the dominant ankle of 13 patients and 16 controls were assessed. The relatio…

MD1003 (High-Dose Pharmaceutical-Grade Biotin) for the Treatment of Chronic Visual Loss Related to Optic Neuritis in Multiple Sclerosis: A Randomized, Double-Blind, Placebo-Controlled Study.

BACKGROUND: Chronic visual loss is a disabling feature in patients with multiple sclerosis (MS). It was recently shown that MD1003 (high-dose pharmaceutical-grade biotin or hdPB) may improve disability in patients with progressive MS. OBJECTIVE: The aim of this study was to evaluate whether MD1003 improves vision compared with placebo in MS patients with chronic visual loss. METHODS: The MS-ON was a 6-month, randomized, double-blind, placebo-controlled study with a 6-month open-label extension phase. Adult patients with MS-related chronic visual loss of at least one eye [visual acuity (VA) b…

Chimeric antigen receptor (CAR) T-cell therapy is rapidly emerging as a transformative approach for treating multiple sclerosis (MS) and other neuroimmune disorders such as neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), and myasthenia gravis (MG), alongside several other rare neuroimmu…

Oligodendrocyte PTEN is required for myelin and axonal integrity, not remyelination.

OBJECTIVE: Repair of myelin injury in multiple sclerosis may fail, resulting in chronic demyelination, axonal loss, and disease progression. As cellular pathways regulated by phosphatase and tensin homologue deleted on chromosome 10 (PTEN; eg, phosphatidylinositol-3-kinase [PI-3K]) have been reported to enhance axon regeneration and oligodendrocyte maturation, we investigated potentially beneficial effects of Pten loss of function in the oligodendrocyte lineage on remyelination. METHODS: We characterized oligodendrocyte numbers and myelin sheath thickness in mice with conditional inactivation…

Hyper-aging in systemic sclerosis: linking genome instability, mitochondrial dysfunction, and inflammaging to fibrosis.

PURPOSE OF REVIEW: Systemic sclerosis (SSc) is a progressive autoimmune disease characterized by fibrosis, vasculopathy, and immune dysregulation. Emerging evidence indicates that SSc shares multiple hallmarks of accelerated biological aging, including genomic instability, telomere attrition, mitochondrial dysfunction, cellular senescence, and chronic innate immune activation. This review summarizes recent advances published during the last 18 months supporting the concept of SSc as a disorder of maladaptive or 'hyper-aging'. RECENT FINDINGS: Recent epigenetic clock studies, including Dunedin

Exploring the Protective Role and the Mechanism of Sphingosine 1 Phosphate in Endotoxic Cardiomyocytes.

FTY720 is a sphingosine 1 phosphate (S1P) receptor agonist approved for the treatment of multiple sclerosis, which is a chronic inflammatory autoimmune disorder. Sepsis is a complex syndrome associated with progressive endotoxemic developments, which finally leads to damage of multiple organs, including the heart. In critical patients, cardiovascular dysfunction due to sepsis is a major cause of death. Previous studies have shown an association between S1P and cardioprotection in the situation of ischemia reperfusion and myocardial infarction. Therefore, we will study the role of S1P towards e…

The gut microbiota-miRNA axis in multiple sclerosis: Mechanisms and therapeutic potentials.

Multiple sclerosis (MS) is a chronic immune-mediated neuroinflammatory and neurodegenerative disease characterized by demyelination, blood-brain barrier disruption, and progressive neurological disability. Increasing evidence identifies the gut microbiota (GM) as a key environmental factor in MS pathogenesis, with microbial dysbiosis contributing to immune dysregulation, impaired intestinal barrier integrity, and chronic systemic inflammation. At the same time, microRNAs (miRNAs) have emerged as pivotal post-transcriptional regulators of immune responses, neuroinflammation, and neurodegenerati…

Follicle on the Roof: Tertiary Lymphoid Structures in Central Nervous System Autoimmunity.

Leptomeningeal tertiary lymphoid structures (TLS) have emerged as a relatively common pathological feature of autoimmune disease, including multiple sclerosis (MS) and particularly in people with progressive and nonremitting MS. These ectopic lymphoid aggregates, observed in the leptomeninges adjacent to so-called "Type 3" sub-pial cortical lesions, are associated with more severe gray matter damage and worse clinical outcomes. Mouse models of MS that recapitulate TLS formation in the central nervous system (CNS) have provided critical insights into the mechanisms driving their development and…

Role of Caveolin-1 in Inflammation: Genetic Predisposition and Potential Implication for Multiple Sclerosis.

Multiple Sclerosis (MS) is a chronic, immune-mediated disorder of the central nervous system characterized by leukocyte infiltration, inflammation, demyelination, and progressive neurodegeneration. Susceptibility to MS is influenced by genetic factors, including variants within the human leukocyte antigen (HLA) region, (notably HLA-DR15), and multiple single nucleotide polymorphisms that modulate T cell function and immune regulation. Clinically, early manifestations such as visual disturbances, sensory deficits, fatigue, and impaired coordination often precede more advanced features, includin…

Transcriptomic profiling and structural characterization reveal UQCRC1 and COX4I1 as key mitochondrial regulators associated with oxidative stress in multiple sclerosis.

Multiple sclerosis (MS) is a chronic immune-mediated disorder of the central nervous system characterized by inflammatory demyelination, progressive neurodegeneration, and irreversible disability. While immune dysregulation initiates disease pathology, the molecular mechanisms linking chronic inflammation to mitochondrial dysfunction and oxidative stress remain incompletely understood. An integrative, multi-layered systems biology approach was applied to four independent RNA-sequencing datasets derived from MS white matter lesions, lesion-border microglia/macrophages, and Epstein-Barr virus-as…

Fingolimod Effects on Motor Function and BDNF-TrkB Signaling in a Huntington's Mouse Model Are Disease-Stage-Dependent.

Huntington's Disease (HD) is characterized by prominent degeneration of the principal neurons of the striatum and by progressive motor and cognitive deterioration. Striatal neurons degenerate in HD due to multiple cell-autonomous and non-autonomous factors. Impaired neurotrophin signaling by brain-derived neurotrophic factor (BDNF) and its cognate receptor Tropomyosin receptor kinase B (TrkB) is an important mechanism underlying neuronal loss in HD. Fingolimod, a clinically approved oral drug for Multiple Sclerosis, was originally developed based on its anti-inflammatory properties. Recent wor…

A Novel Approach to Discriminate Subgroups in Multiple Sclerosis.

Multiple sclerosis (MS) is an autoimmune disease of central nervous system. Since different types of immune cells are involved in MS pathogenesis, in this study we aimed to evaluate serum levels of several immunological components including soluble CD4 (sCD4), sCD8, sCD163, and immunoglobulins as markers of activity of T-cells, macrophages, and B-cells in different types of MS. Serum levels of sCD4, sCD8, and sCD163 of patients with relapsing-remitting MS (RRMS, n=61), primary progressive MS (PRMS, n=31), secondary progressive MS (SPMS, n=31), clinical isolated syndrome (CIS, n=31) and neuromy…

Virus-induced brain pathology and the neuroinflammation-inflammation continuum: the neurochemists view.

Fascinatingly, an abundance of recent studies has subscribed to the importance of cytotoxic immune mechanisms that appear to increase the risk/trigger for many progressive neurodegenerative disorders, including Parkinson's disease (PD), Alzheimer's disease (AD), amyotrophic lateral sclerosis, and multiple sclerosis. Events associated with the neuroinflammatory cascades, such as ageing, immunologic dysfunction, and eventually disruption of the blood-brain barrier and the "cytokine storm", appear to be orchestrated mainly through the activation of microglial cells and communication with the neur…

Linking Personality Traits to Disability Progression in Multiple Sclerosis: A Longitudinal Analysis.

OBJECTIVE: Living with a chronic disease often involves facing many personal changes. In multiple sclerosis (MS), these changes can occur in both physical and psychological domains. Interestingly, psychological factors, including personality traits, have been suggested as potential contributors to disability progression in MS. However, longitudinal studies exploring these associations are scarce. The objective of this study is to highlight and understand long-term associations between personality and disability progression in MS using advanced statistical methods that provide a robust approach…

T Helper Cells: The Modulators of Inflammation in Multiple Sclerosis.

Multiple sclerosis (MS) is a chronic neurodegenerative disease characterized by the progressive loss of axonal myelin in several areas of the central nervous system (CNS) that is responsible for clinical symptoms such as muscle spasms, optic neuritis, and paralysis. The progress made in more than one decade of research in animal models of MS for clarifying the pathophysiology of MS disease validated the concept that MS is an autoimmune inflammatory disorder caused by the recruitment in the CNS of self-reactive lymphocytes, mainly CD4+ T cells. Indeed, high levels of T helper (Th) cells and rel…

Neuropsychiatric Symptoms of Multiple Sclerosis: State of the Art.

Multiple Sclerosis (MS) is a chronic disabling neuroinflammatory disease. Psychiatric manifestations have a high prevalence in MS patients and may worsen the illness progression and the patients' quality of life (QoL). Depression is a highly prevalent condition in MS patients, associated with poorer adherence to treatment, decreased functional status and QoL, and increased suicide risk. Diagnosis and treatment of this disorder is challenging because of symptom overlap. Other prevalent psychiatric comorbidities are anxiety disorders, bipolar disorder, psychotic disorders, substance misuse and p…
