A risk variant in the BDNF gene is tied to increased brain inflammation and reduced cortical thickness on MRI scans in people newly diagnosed with relapsing-remitting multiple sclerosis (RRMS), a recent study found. “We report for the first time an association between the BDNF [genetic variant] and central inflammation…

An increased production of CD25 – an immune receptor that regulates T-cell proliferation and activation – is the most noticeable blood cell immune alteration in people with multiple sclerosis (MS) compared with their unaffected identical twins, a study discovered. The increased CD25 levels, which correlated with disease severity, were…

A researcher at the University of Adelaide, in Australia, has received an AU$390,000 grant (about $280,000) to investigate how inflammatory T-cells reach the blood and brain of people with multiple sclerosis (MS). The 3-year fellowship grant was awarded to Iain Comerford, PhD, for his project, titled “Stopping T cells…

Therapeutics designed to produce new oligodendrocytes — the cells responsible for the protective myelin sheath that is damaged in multiple sclerosis (MS) — might be the most effective approach for disorders such as MS, according to a study conducted in a fish model. That’s because oligodendrocytes that survive being…

Changes in the genome of oligodendrocytes were found in DNA regions associated with immune genes and risk mutations linked to multiple sclerosis (MS), a study shows. The changes identified make it possible for these immune genes and MS-associated regions to have an altered expression — meaning being…

KAT7, an enzyme known to regulate gene activity, is essential for the process of teaching immune T-cells to correctly identify the body’s molecules and cells as ‘self’ — a process that goes awry in multiple sclerosis (MS) and other autoimmune diseases. This enzyme is also critical for training T-cells…

A novel algorithm that combines genetic, environmental, and clinical data could be useful for predicting whether people with a first onset of multiple sclerosis (MS)-like disease — known as clinically isolated syndrome (CIS) — will experience relapses or a worsening of their disease over time. The…

Multiple sclerosis (MS) is characterized by changes in methylation — a type of chemical modification in the DNA that changes how genes are read — in immune cells called T-cells, according to a new study. The results also suggest that treatments for MS can help to normalize methylation…

People with a higher genetic risk for multiple sclerosis (MS) are significantly more likely to develop the disease at an earlier age, a large study found. Specifically, those with the highest genetic risk were on average five years younger at the time their symptoms started than those with the…

A nuclear protein called heterogeneous nuclear ribonucleoprotein A1 or hnRNP A1 — abnormally found outside the nucleus in people with neurodegenerative diseases such as multiple sclerosis (MS) — is essential for nerve cell function and survival. Those are the findings of a new study, by Canadian researchers, of nerve…

Increasing the activity of a gene called Myc can make oligodendrocyte precursor cells, or the cells that repair myelin, more efficient — “ground-breaking research” that could have implications for advancing MS treatments, according to a new study by Cambridge researchers. The study, “Myc determines the functional age…

In an unexpected discovery, scientists working to understand the biological underpinnings of brain tumors found that increasing the activity of a protein receptor called PDGFRA reduces the production of myelin — the fatty coating that is lost in multiple sclerosis (MS) — in the nervous system. “We saw that…

A new research project, funded by the National Institutes of Health (NIH), aims to better understand how different types of cells in the nervous system — specifically neurons and glia cells — communicate with each other and ultimately affect both motor and non-motor functions. Its findings may have important implications…

A variation in a gene called STK11, previously shown to increase the risk for multiple sclerosis (MS) among Caucasians, is now also linked to a greater likelihood of MS in Black people. In fact, the variation was significantly more common in Black MS patients with secondary progressive MS (SPMS),…

A signaling protein called fractalkine helps to regulate the development of oligodendrocytes, cells of the nervous system responsible for making myelin — the protecting coating of nerve cell fibers that is damaged and lost in multiple sclerosis (MS). This finding was in the study, “Fractalkine signaling regulates…

Skin Reactions ‘Frequent’ With Mavenclad, Real-world Study Finds I regularly see people posting on social media about having a rash or itchy skin, or losing hair while taking Mavenclad. Researchers in this study say these side effects aren’t mentioned in the risk management plans for this disease-modifying therapy. Therefore,…

Genetic susceptibility to multiple sclerosis (MS) depends on an individual’s particular combination of multiple risk variants, a study reveals. The study, “Genetic susceptibility to multiple sclerosis: interactions between conserved extended haplotypes of the MHC and other susceptibility regions,” was published in the journal BMC Medical…

Inherited or familial multiple sclerosis (MS) occurs most frequently in children, women, and people living in warmer climates, a new study suggests. Prevalence rates also differ according to geographical areas, with Canada exhibiting the highest rates and Hungary the lowest. The study, “The global prevalence of familial multiple sclerosis:…

Children born to women with multiple sclerosis (MS) are not at a higher risk of brain disorders than are children whose mothers don’t have this disease, an observational study reported. However, children born to women with a family with a history of other autoimmune conditions and brain disorders, or…

T-cells in the fluid around the brain share a large percentage of receptors among different multiple sclerosis (MS) patients, a new report suggests. Better understanding the diversity of T-cell receptors in MS, and how these cells vary in different parts of the body, could be useful in understanding the…

The enzyme TET1, which is progressively lost with age, is essential to activate genes needed to repair myelin — the sheath around nerve cells that is damaged in people with multiple sclerosis (MS) — a study in mice has found. The…
