The aim of the present study was to investigate the effects of high-intensity interval training (HIIT) versus low-intensity continuous training (LICT) on transcriptional levels of neurotrophic factors and oligodendrocyte/microglia cell loss in a cuprizone (CP) induced animal model of demyelination. Male C57BL/6 mice were assigned to six groups: control (C), cuprizone-induced demyelination (CP), interval training (IT), continuous training (CT), IT plus CP (ITCP), and CT plus CP (CTCP). Training programs on the treadmill were performed for four weeks, and then demyelination was induced by feeding mice a diet containing 0...

Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of the CNS. In addition to motor, sensory and visual deficits, MS is also characterized by hippocampal demyelination and memory impairment. We recently demonstrated that a recombinant human-derived monoclonal IgM antibody, which is designated rHIgM22 and currently in clinical development for people with MS, accelerates remyelination of the corpus callosum in the brains of cuprizone-treated mice. Here, we investigated the effects of rHIgM22 in the hippocampus and on hippocampal-dependent learning and memory in the same mouse model of cuprizone-induced demyelination and spontaneous remyelination...

An intermittent fasting or calorie restriction diet has favorable effects in the mouse forms of multiple sclerosis (MS) and may provide additional anti-inflammatory and neuroprotective advantages beyond benefits obtained from weight loss alone. We conducted a pilot randomized controlled feeding study in 36 people with MS to assess safety and feasibility of different types of calorie restriction (CR) diets and assess their effects on weight and patient reported outcomes in people with MS. Patients were randomized to receive 1 of 3 diets for 8 weeks: daily CR diet (22% daily reduction in energy needs), intermittent CR diet (75% reduction in energy needs, 2 days/week; 0% reduction, 5 days/week), or a weight-stable diet (0% reduction in energy needs, 7 days/week)...

Multiple sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system. In addition to the genetic, epigenetic and immunological components, various other factors e.g. unhealthy dietary habits play a role in the MS pathogenesis. Dietary intervention is a highly appealing approach, as it presents a simple and relatively low risk method to potentially improve outcomes in patients with brain disorders in order to achieve remission and improvement of clinical status, well-being and life expectancy of patients with MS...

Immune mediated diseases (IMDs) are complex chronic inflammatory diseases involving genetic and environmental factors. Salt intake has been proposed as a diet factor that can influence the immune response. Indeed, experimental data report the influence of sodium chloride on the differentiation of naive CD4+ T cells into IL-17 secreting T helper (Th) cells (Th17 cells), by a mechanism involving the serum glucocorticoid kinase-1 (SGK1) that promotes the expression of the IL-23 receptor (IL-23R). The IL-23/IL-23R is critical for pathogenic inflammatory Th17 cell differentiation...

Epidemiology of Multiple Sclerosis (MS) has been intensively studied and we know now that its occurrence result from the combined action of genetic and environmental factors. There are significant geographic and temporal variations in MS incidence and the risk associated with the development of MS may be affected by many potential factors (including infections, climate, diet, etc.). But none of these factors has been identified as "causal". The accumulation of these different agents as well as their interactions probably contribute to the development of the disease...

Weight loss has substantial health benefits, but it is not risk-free. Various neurological disorders have been reported following bariatric surgery-induced weight loss. Here, we report 3 patients who developed multiple sclerosis (MS), one of whom also developed myasthenia gravis (MG), shortly after significant weight loss. Two patients lost weight by following a diet plan and one underwent bariatric surgery. There may be an association between significant weight loss and the development of an autoimmune neurological disorder such as MS or MG; a high index of suspicion is required...

Neurodegeneration is a critical problem in aging populations and is characterized by severe central nervous system (CNS) inflammation. Macrophages closely regulate inflammation in the CNS and periphery by taking on different activation states. The source of inflammation in many neurodegenerative diseases has been preliminarily linked to a decrease in the CNS M2 macrophage population and a subsequent increase in M1-mediated neuroinflammation. The Recepteur D'Origine Nantais (Ron) is a receptor tyrosine kinase expressed on tissue-resident macrophages including microglia...

Background/objectives: Although the current evidence is insufficient to recommend a special diet for people with multiple sclerosis (MS), dietary advice for people with MS is prolific online and in the media. This study aimed to describe dietary changes made in the year following a first clinical diagnosis of central nervous system demyelination (FCD), a common precursor to MS. Subjects/methods: We used follow-up data from the Ausimmune Study, a multicentre matched case-control study examining the environmental risk factors for a FCD...

Purpose: Pediatric-onset multiple sclerosis (POMS) accounts for ~5% of all multiple sclerosis cases, and has a prevalence of ~10,000 children in the USA. POMS is associated with a higher relapse rate, and results in irreversible disability on average 10 years earlier than adult-onset multiple sclerosis. Other manifestations of POMS include mental and physical fatigue, cognitive impairment, and depression. We believe that the health behaviors of physical activity, diet, and sleep may have potential benefits in POMS, and present a scoping review of the existing literature...

Multiple sclerosis (MS) is a demyelinating and inflammatory disease. Myelin is enriched in lipids, and more specifically, oleic acid. The goal of this study was to evaluate the concentration of oleic acid following demyelination and remyelination in the cuprizone model, test if these changes occurred in specific lipid species, and whether differences in the cuprizone model correlate with changes observed in post-mortem human brains. Eight-week-old C57Bl/6 mice were fed a 0.2% cuprizone diet for 5 weeks and some animals allowed to recover for 11 days...

B cells possess a predominant role in adaptive immune responses via antibody-dependent and -independent functions. The microbiome of the gastrointestinal tract is currently being intensively investigated due to its profound impact on various immune responses, including B cell maturation, activation, and IgA antibody responses. Recent findings have demonstrated the interplay between dietary components, gut microbiome, and autoantibody production. "Western" dietary patterns, such as high fat and high salt diets, can induce alterations in the gut microbiome that in turn affects IgA responses and the production of autoantibodies...

PURPOSE OF REVIEW: This review aims to critically evaluate published studies examining diets and nutritional supplements (excepting vitamin D) for the impact on prevention and prognosis of multiple sclerosis (MS). RECENT FINDINGS: There is a negative relationship between the Mediterranean diet and vascular disease, and vascular co-morbidities are associated with a worse MS prognosis. Low-fat, fish-based diets, sodium-restricted diets, calorie restriction, the paleo diet, and gluten-free diets have been examined, mostly in observational studies; results are inconclusive...

Optic neuritis is an acute inflammatory demyelinating disorder of the optic nerve (ON) and is an initial symptom of multiple sclerosis (MS). Optic neuritis is characterized by ON degeneration and retinal ganglion cell (RGC) loss that contributes to permanent visual disability and lacks a reliable treatment. Here, we used the experimental autoimmune encephalomyelitis (EAE) mouse model of MS, a well-established model also for optic neuritis. In this model, C57BL6 mice, intraperitoneally injected with a fragment of the myelin oligodendrocyte glycoprotein (MOG), were found to develop inflammation, Müller cell gliosis, and infiltration of macrophages with increased production of oncomodulin (OCM), a calcium binding protein that acts as an atypical trophic factor for neurons enabling RGC axon regeneration...

INTRODUCTION: Dietary approaches to management of MS has been proposed for several decades, yet very little is known concerning dietary composition or adherence to specialized diets in people with multiple sclerosis (MS). METHODS: We conducted a survey of participants in the North American Research Committee on MS (NARCOMS) registry assessing diet composition and the prevalence of 19 different diets. We characterized prevalence of different diets and compared diet composition with estimated intakes from the National Health and Nutrition Examination Survey (NHANES) survey respondents and across demographics and MS clinical characteristics...

Cuprizone (CZ) is a widely used copper chelating agent to develop non-autoimmune animal model of multiple sclerosis, characterized by demyelination of the corpus callosum (CC) and other brain regions. The exact mechanisms of CZ action are still arguable, but it seems that the only affected cells are the mature oligodendrocytes, possibly via metabolic disturbances caused by copper deficiency. During the pathogenesis of multiple sclerosis, high amount of deposited iron can be found throughout the demyelinated areas of the brain in the form of extracellular iron deposits and intracellularly accumulated iron in microglia...
