Impact of Lifestyle Interventions on Multiple Sclerosis: Focus on Adipose Tissue www.mdpi.com Sept. 16, 2024, 11:15 a.m.
MS is a chronic autoimmune disease affecting the CNS over a long-term period. The severity of MS varies widely and is influenced by several factors, comprising the endocrine activity of AT. The involvement of AT in MS pathogenesis remains to be further clarified; certainly, MS is characterized by an altered immune response in which AT also participates through dysregulated adipokine secretion, increasing the risk of disease development and accelerating its progression. Based on the data presented in this review, it is plausible that the functionality of AT is positively influenced by lifestyle factors such as physical activity and nutrition, which are essential in the management of MS.

Découverte du premier variant génétique qui aggrave la sclérose en plaques www.sciencesetavenir.fr June 29, 2023, 5:26 a.m.
Pour la première fois, un élément crucial de la progression de la maladie vient d'être mis au jour : le premier variant génétique associé à une sévérité accrue de la sclérose en plaques. Dans l'ADN, les variants sont des changements permanents sur les gènes. On les appelle des "polymorphismes" lorsque ces changements sont fréquents dans la population ou des "mutations" lorsque le changement est rare. Peu importe leur nature, les variants, de par les modifications qu'ils entraînent dans l'ADN, peuvent être à l'origine de maladies.

A physical therapist reflects on her multiple sclerosis diagnosis www.statnews.com Nov. 28, 2022, 11:08 p.m.
A little under 10 years ago, Leigh Krauss was almost done with her schooling to become a physical therapist. A former guard on the women’s basketball team at Trinity College in Hartford, Conn., she had always been active and healthy. That is, until one day, walking to class, she lost vision in one eye. Krauss was soon diagnosed with multiple sclerosis, a chronic autoimmune disease where nervous system glitches cause a disconnect between the brain and the body.
The Impact Of Multiple Sclerosis On The Body dralexjimenez.com July 29, 2022, 10:32 a.m.
Everyone knows that the brain is the command center of the body. This organ is part of the central nervous system that works with the spinal cord and the vital organ systems to send signals that provide motor-sensory functions to make the body do everyday movements. The signals from the brain have a casual relationship with the immune system. When environmental factors enter the body, the brain signals the immune system to send inflammatory cytokines to the area where it was affected and begin the body’s healing process. The immune system helps clean up the body’s cellular structure by replacing old, damaged cells with new, healthy cells. However, when the immune system starts to attack specific parts of the body mistakenly, it can damage the healthy cells causing autoimmune diseases to develop in the body.

Molecular Basis of Multiple Sclerosis Development and Treatment www.mdpi.com July 29, 2022, 10:26 a.m.
The progress that has been made in developing new immune-modifying therapies for MS in recent years is fascinating. Nevertheless, all current drugs fail to prevent neurodegeneration. Moreover, not only are the molecular and cellular mechanisms underlying their effects not completely characterized, but the specificity also needs to be improved in order to spare the protective cellular subtypes.
The Role of Antibodies in the Pathogenesis of Multiple Sclerosis pubmed.ncbi.nlm.nih.gov July 29, 2022, 10:24 a.m.
The presence of persistent intrathecal oligoclonal immunoglobulin G (IgG) bands (OCBs) and lesional IgG deposition are seminal features of multiple sclerosis (MS) disease pathology. Despite extensive investigations, the role of antibodies, the products of mature CD19+ B cells, in disease development is still controversial and under significant debate. Recent success of B cell depletion therapies has revealed that CD20+ B cells contribute to MS pathogenesis via both antigen-presentation and T-cell-regulation. However, the limited efficacy of CD20+ B cell depletion therapies for the treatment of progressive MS indicates that additional mechanisms are involved. In this review, we present findings suggesting a potential pathological role for increased intrathecal IgGs, the relation of circulating antibodies to intrathecal IgGs, and the selective elevation of IgG1 and IgG3 subclasses in MS.
Switching Disease Modifying Therapies in Multiple Sclerosis Fact Sheet my.clevelandclinic.org July 29, 2022, 10:22 a.m.
None of the currently available disease modifying therapy is 100% effective in halting disease activity; therefore, it is not unexpected that patients may experience breakthrough disease activity while on therapy during their disease courses. If breakthrough disease activity is observed while the patient has been confirmed to be treatment-compliant, and sufficient time has passed to allow for full physiologic effect of disease modifying therapy since initiation, then a switch should be considered. Response to disease modifying therapy is difficult to define given ambiguity of monitoring criteria.

Longitudinal analysis reveals high prevalence of Epstein-Barr virus associated with multiple sclerosis www.science.org Feb. 10, 2022, 10:50 p.m.
Multiple sclerosis is a chronic demyelinating disease of the central nervous system. The underlying cause of this disease is not known, but Epstein-Barr virus is thought to be a possible culprit. However, most people infected with this common virus do not develop multiple sclerosis, and it is not feasible to directly demonstrate causation of this disease in humans. Using data from millions of US military recruits monitored over a 20-year period, Bjornevik et al. determined that Epstein-Barr virus infection greatly increased the risk of subsequent multiple sclerosis and that it preceded the development of disease, supporting its potential role in the pathogenesis of multiple sclerosis (see the Perspective by Robinson and Steinman). —YN
Induction and stability of vaccine-specific antibodies in multiple sclerosis patients on different disease-modifying therapies www.news-medical.net Feb. 10, 2022, 10:49 p.m.
The authors highlight that they have confirmed that the antibody response in the treated patients was significantly lower than in the control groups, in some cases virtually absent, and that this is likely at least partially due to the impaired humoral responses seen in these groups. As well as this, the T cell response to the spike protein is significantly muted in fingolimod-treated patients. The correlation analyses helped show that the length of treatment and reduced capacity to respond to the antibody is likely linked.
The Gut Microbiome in Multiple Sclerosis: A Potential Therapeutic Avenue www.ncbi.nlm.nih.gov Feb. 10, 2022, 10:48 p.m.
The findings suggest that the interactions between the host and the microbiota are reciprocal, although more extensive work is required to confirm this. Moreover, evidence indicates that changes in microbiota composition may result in imbalances that could result in disease, with the gut as a potential novel therapeutic avenue. By understanding the biological effects of aberrant gut microbiome composition, it is possible to contemplate current therapeutic options and their efficacy. Ultimately, more research is necessary in this field, but targeting the gut microbiota may lead to the development of novel therapeutic strategies.
3 Biotech Leaders In Multiple Sclerosis Innovation www.sickeconomics.com Feb. 10, 2022, 10:46 p.m.
Multiple sclerosis is one of the most detrimental progressive diseases that doesn’t have a cure. Even if it were to be caught early, the current treatment can only slow the progression of multiple sclerosis by reducing nerve cell inflammation and damage. Basically, multiple sclerosis is where the protective coating of nerves in the spinal cord and the brain gets damaged and destroyed by the body’s own immune system. So it can lead to symptoms such as vision loss, muscle spasms, and impaired coordination. Unfortunately, the cause of this disease is unknown.
