Scientists at Case Western Reserve University (CWRU) in Ohio will use a new $2.5 million donation from the Thomas F. Peterson Jr. Charitable Trust to develop therapeutic strategies for multiple sclerosis (MS) and other neurological diseases. The commitment will support Paul Tesar, PhD, a CWRU professor and director of the…
Researchers have identified a protein that naturally slows myelin production — a finding that could lead to ways to repair myelin damage in multiple sclerosis (MS) and other neurological disorders. In mice, the protein (called Tfii-i) was found to limit the activity of genes that drive myelin formation. When…
A gene on the X chromosome that is more active in women than men appears to drive inflammation in the brain, helping to explain why women are more likely to develop neurological diseases such as multiple sclerosis (MS) and Alzheimer’s disease, according to a study out of the…
Researchers have identified a genetic biomarker that predicts whether people with relapsing forms of multiple sclerosis (MS) will respond to glatiramer acetate (sold as Copaxone, among others) therapy. A study based on an analysis of more than 3,000 MS patients showed that those who carry a form of…
A research project to explore the genetic connection between the Epstein-Barr virus (EBV) and the risk of developing multiple sclerosis (MS) has been awarded a $24,400 incubator grant by the nonprofit MS Australia. Titled “A novel use of human genetics to recruit participants for MS research,” the…
Multiple sclerosis (MS) may increase the risk of developing Alzheimer’s disease, according to a new analysis of genetic data. The findings indicate genetic changes that influence the activity of immune T-cells may play a role in both MS and Alzheimer’s. The study, “Multiple sclerosis…
Pro-inflammatory signaling molecules that have been implicated in multiple sclerosis (MS) cause problems with the growth and development of myelin-making cells in the brain, according to a study done in cell models. The findings may have implications for treating MS, as promoting the growth of myelin-making cells could be…
As multiple sclerosis (MS) progresses, the disease may reduce the number of mitochondrial DNA copies, suggesting the number of copies could serve as a biomarker for disease progression and response to treatment. That’s according to a genetic study involving data from thousands of patients of European ancestry. Mitochondria are…
Elevated levels of two bacterial strains from the Lachnospiraceae family in the gut may be a key risk factor for multiple sclerosis (MS), according to a study. The study, “Multiple sclerosis and gut microbiota: Lachnospiraceae from the ileum of MS twins trigger MS-like disease in germfree…
The risk of multiple sclerosis (MS) is significantly higher in people who carry a variant of the HLA gene called HLA-E*01:01 and have a history of infectious mononucleosis (mono), the manifestation of an Epstein-Barr virus (EBV) infection, according to a study based on U.K. Biobank data. The higher…
A researcher and neurologist at Penn Medicine in Philadelphia has won the 2025 John Dystel Prize for Multiple Sclerosis Research for his work in uncovering immune mechanisms of multiple sclerosis (MS), identifying disease biomarkers, and finding new avenues toward tailored medicine. The prize comes with a sculpture and…
Antibodies that target proteins from the Epstein-Barr virus (EBV) also can inadvertently attack proteins in the brain, which may help to explain the link between EBV and multiple sclerosis (MS), a new study shows. Findings also indicate that antibodies targeting EBV as well as a person’s genetics both…
Neurons, also called nerve cells, collected from brain lesions of people with multiple sclerosis (MS) were found to accumulate new genetic mutations at a significantly faster rate than healthy neurons did, according to a new report. The researchers also found that neurons in such lesions exhibited distinct mutation…
A new model that combines genetic and symptom-based risk scores to predict the development of multiple sclerosis (MS) could help to accelerate the disease’s diagnosis, and allow patients to receive earlier treatment, a team of U.S. researchers noted in a study. In a presentation detailing this work at this…
An interplay between genetic and environmental risk factors, including tobacco smoke exposure, affects brain development in early childhood, which could increase the likelihood a person will develop multiple sclerosis (MS), according to a recent study. Among young children in the Netherlands, being at a high genetic risk for MS,…
Researchers at the Oregon Health & Science University have discovered a plant-derived small molecule that can promote the growth of cells that produce myelin, the protective coating around nerve fibers that’s damaged in multiple sclerosis (MS). The naturally occurring molecule, sulfuretin, blocks the activity of an enzyme that…
Abnormal activity of ancient viral genes may play a role in the development of multiple sclerosis (MS) and other neurological disorders, a study found. “Future functional studies are essential to elucidate the molecular and cellular mechanisms underlying their involvement in these conditions,” the researchers wrote. The study, “…
Transplanting genetically engineered oligodendrocyte progenitor cells (OPCs), which give rise to mature myelin-making cells, significantly boosted myelin repair in mice with multiple sclerosis (MS)-like chronic brain lesions. The cells were engineered to ignore chemical signals that would normally inhibit OPCs being recruited into lesions and then restore…
By studying pairs of identical twins, researchers have identified a population of immune cells whose early activation and migration into the brain might contribute to multiple sclerosis (MS) onset. MS patients showed an altered profile of a population of immune cells called CD8 T-cells in the blood relative to…
People with multiple sclerosis (MS) are about half as likely as those without the disease to have signs of the amyloid-beta plaques in the brain that are a hallmark of Alzheimer’s disease, according to a study in the U.S. “Our findings imply that some component of the biology…
A specific epigenetic marker, or a chemical modification in DNA that alters gene activity, may explain why adult oligodendrocyte progenitor cells respond differently to therapies aiming to restore myelin than their neonatal counterparts, a study reports. The modification, called a lysine eight acetylation on histone H4, helps to regulate…
Using a newly developed molecular analysis, a research team has discovered previously unknown subsets of immune cells and genes that may play a role in multiple sclerosis (MS) and other immune-mediated diseases. “We discovered new types of helper T cells as well as genes related to immune disorders. We…
Alexander Gow, PhD, a professor at Wayne State University School of Medicine in Detroit, has been awarded a grant to study how stressed oligodendrocytes, the cells that produce myelin in the brain and spinal cord, could be at the origin of multiple sclerosis (MS). The three-year, $644,827 grant from…
When I was initially evaluated for multiple sclerosis (MS), I was asked if I had a family history of the disease. To my knowledge, I did not. Once I received my diagnosis, one of the first things that crossed my mind, after recovering from the initial shock…
