While the physical disability is widely known to influence the QoL, the relative contributions of cognitive impairm…

Eomes-expressing T-helper cells as potential target of therapy in chronic neuroinflammation.

Reserch progresses in understanding the pathogenicity of multiple sclerosis (MS) in the last couple of decade has enabled us to develop new drug entities available in the clinic. However, we still have not succeeded in preventing conversion from relapsing-remitting MS (RR-MS) to secondary progressive MS (SP-MS) and curing this intractable form of MS. Furthermore, diagnosis is usually retrospective and subjective, relying on gradual worsening of neurological signs/symptoms. This is obviously due to the lack of understanding for the pathogenicity driving disease progression in MS and of reliable…

LRR domain of NLRX1 protein delivery by dNP2 inhibits T cell functions and alleviates autoimmune encephalomyelitis.

Multiple sclerosis (MS) is a demyelinating inflammatory disease of the central nervous system (CNS), which is a chronic progressive disease and is caused by uncontrolled activation of myelin antigen specific T cells. It has high unmet medical needs due to the difficulty of efficient drug delivery into the CNS to control tissue inflammation. In this study, we demonstrate that a fusion protein of NOD-like receptor family member X1 (NLRX1) and blood brain barrier (BBB)-permeable peptide, dNP2 ameliorates experimental autoimmune encephalomyelitis (EAE). Methods: We purified recombinant LRR or NBD …

Cellular Senescence in Neurodegeneration: From Cell Types to Therapeutic Opportunities.

Neurodegenerative diseases of the central nervous system, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis, represent a growing health challenge in ageing populations. Among the mechanisms underlying these disorders, increasing attention has been directed toward the role of cellular senescence. This process, triggered by chronic cellular and oxidative stress as well as DNA damage, leads to irreversible cell-cycle arrest and the development of the senescence-associated secretory phenotype (SASP). Within the central nervous system, the accumulation of senescent cells indu…

Immune reconstitution for the treatment of myasthenia gravis: the focus on cladribine.

Autoimmune diseases (AID) such as multiple sclerosis, rheumatoid arthritis, type 1 diabetes, inflammatory neuropathies, and some 100 other conditions, affect 5-10% of the global population, and their incidence is increasing, particularly in women. Among these, myasthenia gravis (MG) is a relatively rare but debilitating disease, which represents a prototype antibody-mediated autoimmune condition with well-studied pathogenesis. MG is a neuromuscular junction disorder marked clinically by fatigable muscle weakness and serologically by the presence of pathogenic autoantibodies. In MG pathological…

Mechanisms in the loss of capillaries in systemic sclerosis: angiogenesis versus vasculogenesis.

Systemic sclerosis (SSc, scleroderma) is a chronic, multisystem connective tissue disorder affecting the skin and various internal organs. Although the disease is characterized by a triad of widespread microangiopathy, fibrosis and autoimmunity, increasing evidence indicates that vascular damage is a primary event in the pathogenesis of SSc. The progressive vascular injury includes persistent endothelial cell activation/damage and apoptosis, intimal thickening, delamination, vessel narrowing and obliteration. These profound vascular changes lead to vascular tone dysfunction and reduced capilla

Effectiveness of first-line treatment for relapsing-remitting multiple sclerosis in Brazil: A 16-year non-concurrent cohort study.

BACKGROUND: Relapsing-remitting multiple sclerosis (RRMM) is a chronic, progressive, inflammatory and immune-mediated disease that affects the central nervous system and is characterized by episodes of neurological dysfunction followed by a period of remission. The pharmacological strategy aims to delay the progression of the disease and prevent relapse. Interferon beta and glatiramer are commonly used in the Brazilian public health system and are available to patients who meet the guideline criteria. The scenario of multiple treatments available and in development brings the need for discussi…

Long-term disability trajectories in primary progressive MS patients: A latent class growth analysis.

BACKGROUND: Several natural history studies on primary progressive multiple sclerosis (PPMS) patients detected a consistent heterogeneity in the rate of disability accumulation. OBJECTIVES: To identify subgroups of PPMS patients with similar longitudinal trajectories of Expanded Disability Status Scale (EDSS) over time. METHODS: All PPMS patients collected within the MSBase registry, who had their first EDSS assessment within 5 years from onset, were included in the analysis. Longitudinal EDSS scores were modeled by a latent class mixed model (LCMM), using a nonlinear function of time from o…

Use of Magnetic Resonance Imaging to Visualize Leptomeningeal Inflammation in Patients With Multiple Sclerosis: A Review.

IMPORTANCE: Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system traditionally characterized by an initial relapsing-remitting clinical course and focal inflammatory lesions that have a predilection for the periventricular white matter. Recently, however, histopathologic and imaging studies have illustrated a more complex pathologic substrate involving cortical demyelination, gray matter atrophy, and meningeal inflammation. Neuroimaging advances have facilitated improved detection of cortical pathology, but our understanding of the pathogenesis of cortical d…

Oligodendrocyte и Myelin патофизиология в мультиклерозе.

Множественный склероз (MS) — хроническое аутоиммунное и прогрессивное нейродегенеративное заболевание центральной нервной системы (CNS), имеющее весьма изменчивое клиническое проявление и курс. MS преследует главным образом миелина и олигодендроглию; однако все глиальные клетки и нейроны начинают участвовать в патологии. Таким образом, воспаление, которое широко считается инициированным в периферии, расширяется через CNS, причем астроциты и микроглиа попадают в активированное состояние не только вокруг и внутри повреждений, но и широко распространены. В этой главе будут подчеркнуты патофизиоло

Multiple sclerosis (MS) is a chronic autoimmune and progressive neurodegenerative disease of the central nervous system (CNS) that has a highly variable clinical manifestation and course. MS targets primarily myelin and oligodendroglia; however, all glial cells and neurons become involved early in the pathology. Thus, inflammation, which is widely thought to…

Nutrients and bioactive compounds as modifiers of neurodegenerative trajectories: molecular mechanisms, translational barriers, and precision nutrition.

The Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS) are a growing health burden across the world with minimal disease-modifying treatment and therapy. It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and sub…

Neuron-specific activation of necroptosis signaling in multiple sclerosis cortical grey matter.

Sustained exposure to pro-inflammatory cytokines in the leptomeninges is thought to play a major role in the pathogenetic mechanisms leading to cortical pathology in multiple sclerosis (MS). Although the molecular mechanisms underlying neurodegeneration in the grey matter remain unclear, several lines of evidence suggest a prominent role for tumour necrosis factor (TNF). Using cortical grey matter tissue blocks from post-mortem brains from 28 secondary progressive MS subjects and ten non-neurological controls, we describe an increase in expression of multiple steps in the TNF/TNF receptor 1 si…

Immune responses against Helicobacter pylori-specific antigens differentiate relapsing remitting from secondary progressive multiple sclerosis.

To assess whether Helicobacter pylori (Hp) antibody (ab) reactivity against individual Hp antigens is pathogenetically relevant to multiple sclerosis (MS), we systematically investigated prevalence and clinical significance of abs against 14 immunodominant and subdominant Hp antigens by ELISA and immunoblotting in 139 consecutive MS patients with relapsing-remitting (RRMS, n = 102) or secondary progressive (SPMS, n = 37). Sera from 39 patients with Parkinson's disease (PD), 21 with Alzheimer's disease (ALZ) and 68 healthy controls (HCs), were also tested. Anti-flagellin (18.3%) and anti-p41 (2…

Other covariates controlled for in the multivariate regression included disease duration (years), use of d …

Microglia: The Missing Link to Decipher and Therapeutically Control MS Progression?

Therapeutically controlling chronic progression in multiple sclerosis (MS) remains a major challenge. MS progression is defined as a steady loss of parenchymal and functional integrity of the central nervous system (CNS), occurring independent of relapses or focal, magnetic resonance imaging (MRI)-detectable inflammatory lesions. While it clinically surfaces in primary or secondary progressive MS, it is assumed to be an integral component of MS from the very beginning. The exact mechanisms causing progression are still unknown, although evolving evidence suggests that they may substantially di…
