Multiple sclerosis (MS) is a multicomponent disease characterized by inflammation, neurodegeneration, and cancellation of the central nervous system recovery mechanisms. The cause of MS is still unknown, but it is undeniable that genetic, environmental and immune factors are involved in the etiopathogenesis of this complex and heterogeneous disease. From the aspect of immunopathogenesis, until recently the opinion prevailed that autoreactive T lymphocytes played a major role, the activation of which is a key step in MS. The knowledge of the effector and regulatory roles of B cells supports a new concept of MS immunopathogenesis that is based on the highly com-plex interaction of T and B cells, with B cells actively participating in cellular immunity by directing the intensity and quality of cellular immune response. The mechanisms of B cell activity in MS immunopathogenesis are multiple and include antigen presentation and T cell costimulation, cytokine secretion, antibody synthesis, and formation of ectopic lymphoid B cell aggregates in the intrameningeal spaces. The importance of B cells has been confirmed by modern therapeutic options for the treatment of MS.

The imbalance between Tregs and proinflammatory Th17 cells in children with biliary atresia (BA) causes immune damage to cholangiocytes. Dimethyl fumarate (DMF), an immunomodulatory drug, regulates the Treg/Th17 balance in diseases like multiple sclerosis (MS). This study explores DMF's effect on Treg/Th17 balance in BA and its potential mechanism.

Background: Evidence from preclinical studies suggests that IL-6 signalling has the potential to modulate immunopathogenic mechanisms upstream of autoantibody effector mechanisms in patients with generalised myasthenia gravis. We aimed to assess the safety and efficacy of satralizumab, a humanised monoclonal antibody targeting the IL-6 receptor, in patients with generalised myasthenia gravis.
Methods: LUMINESCE was a randomised, double-blind, placebo-controlled, multicentre, phase 3 study at 105 sites, including hospitals and clinics, globally.

There is currently no cure or disease-modifying treatment for post-traumatic osteoarthritis (PTOA). This study aims to assess the efficacy of dimethyl fumarate (DMF), a US-FDA approved drug for multiple sclerosis, as a treatment for PTOA. PTOA was induced in male Lewis rats by medial meniscal transection (MMT) surgery, and DMF was intra-articularly administered once, one week following surgery.

Background/objective: Identifying research priorities of Veterans, MS researchers, and key stakeholders is critical to advance high-quality, evidence-based, and Veteran-specific MS care.
Methods: We used a modified Delphi approach to identify research priorities for Veterans with MS. Electronic surveys were distributed to Veterans with MS (n = 50,975), MS researchers (n = 191), VA healthcare providers (1,337), and funding agency representatives (n = 6) asking about their 2-3 most important research questions that would benefit Veterans with MS for researchers to answer in the next 5-10 years.

Multiple sclerosis (MS) is a chronic autoimmune disorder marked by neuroinflammation, demyelination, and neuronal damage. Recent advancements highlight a novel interaction between iron-dependent cell death, known as ferroptosis, and gut microbiota, which may significantly influences the pathophysiology of MS. Ferroptosis, driven by lipid peroxidation and tightly linked to iron metabolism, is a pivotal contributor to the oxidative stress observed in MS.
