Immune cell influences on neuronal viability and repair

Summary: microRNAs are molecules which have been implicated in regulating neurons in response to inflammatory stimuli. They have the ability to silence the expression of many genes at once. Whether microRNAs can silence many genes that prevent nerve cell repair simultaneously is unknown. The research... Read the full article

Bacillus Calmette-Guerin (BCG) vaccination and multiple sclerosis: A population-based study in Quebec

Affiliation: Institut national de la recherche scientifique (INRS) Summary: Bacillus Calmette-Guerin (BCG) vaccine, which is normally given to protect against tuberculosis, can slow short-term multiple sclerosis (MS) progression. It is unknown if having received the BCG vaccine as a child could prevent... Read the full article

A Randomized, Controlled, Clinical Trial of Continuous Positive Airway Pressure Treatment of Obstructive Sleep Apnea-Hypopnea in Multiple Sclerosis

Summary: Poor sleep is a problem for many people with multiple sclerosis (MS) and is related to fatigue. Whether treatment of sleep disorders can markedly improve fatigue and other symptoms in some MS patients needs to be tested in a study. The research team is: Conducting a randomized, controlled, Read the full article

Effects of FES cycling combining leg and trunk muscle stimulations in persons with multiple sclerosis: a pilot study

Summary: Exercising slows progression, reduces pain and maintains good physical and mental health in multiple sclerosis (MS). Functional electrical stimulation(FES) is one approach where a mild electrical stimulation is applied to the muscle groups to promote movement. While some studies have identified...

Understanding Multiple Sclerosis Cortical Pathology From a Neuroanatomical Perspective: Laminar Quantitative MRI Analysis of Cortical Neuroinflammation

Summary: MS is often characterized by the damage (or lesions) in the brain and spinal cord. One type of MS lesion particularly widespread is called a "sub-pial" cortical lesion. It lies along the surface of the brain. This research team is developing improved methods to detect "sub-pial" lesions using... Read the full article

The Interleukin-1 Cytokine System as a Target for the Treatment of Multiple Sclerosis

Summary: The molecule, interleukin (IL)-1ß, has been identified as a key messenger involved in the development and severity of central nervous system autoimmunity. IL-1ß may be acting like a key that opens the door to the central nervous system, allowing entry of aggressive immune cells in to the brain... Read the full article

Targeting T Cell Metabolism to Reduce Neuroinflammation in Multiple Sclerosis

Summary:  Western diet, obesity and related comordities are risk factors for MS onset and progression. Scientific evidence shows that restricting intake of methionine, an essential amino acid found in high-levels in meat-based diets, is associated with a prolonged lifespan (anti-aging), slower cancer...

Characterization of a Novel Dendritic Cell-specific Protein in Demyelinating Autoimmune Diseases

Summary: Autoreactive immune cells called T cells play a central role in diseases such as multiple sclerosis (MS) and MS-like animal models (EAE mouse model). To perform their role, T cell activity is regulated by dendritic cells (DC). Recently, the team found a novel cell-surface protein of unknown... Read the full article

Sex Chromosomes Dictate T Cell (Th17) Pathogenicity
