Sustained, excessive levels of interleukin 17A (IL-17A) — a pro-inflammatory molecule linked to multiple sclerosis (MS) and other autoimmune diseases — reduce the number and activity of the brain’s immune cells in the dentate gyrus, according to a study in mice. The dentate gyrus is part of the hippocampus, a…

An antibody analysis has identified two biomarkers that can be used to predict the development of multiple sclerosis (MS) in people with optic neuritis, a study reports.  Further research is, however, required to validate these findings…

National MS Society Urges DMT Dosing Changes for COVID-19 Vaccinations The National MS Society has revised its COVID-19 vaccine recommendations first issued about a month ago. The guidelines still say the Moderna and Pfizer vaccines are considered safe for people with MS, including those using disease-modifying therapies, or DMTs.

Proteins called PSGs suppress the pro-inflammatory activity of immune Th17 cells during pregnancy, potentially playing a protective role against complications and miscarriage, a study finds.  The impaired regulation of Th17 is associated with pregnancy complications, like preeclampsia and preterm delivery — and also with the development…

The levels of KIF5A protein are elevated in the cerebrospinal fluid (CSF) — the liquid surrounding the brain and spinal cord — of people with progressive multiple sclerosis (MS) and, further, are correlated with disease progression measures in patients with relapsing-remitting MS (RRMS), a new study shows. These…

C. Light Technologies announced it raised $2.5 million in seed funding to further develop a noninvasive eye tracking device that might diagnose multiple sclerosis (MS) and other neurological diseases through measures made in a matter of seconds. Currently a prototype, the device captures neurodegeneration by mapping what is called fixational…

Asymptomatic damage to spinal nerves occurs even in clinically stable cases of multiple sclerosis (MS) and carries an increased risk for further lesions, a recent study suggests. Although a firm link between the asymptomatic loss of myelin in the spine and worsening disability remains to be found, this work…

An estrogen-based therapy, called indazole chloride (IndCl), was shown to protect against optic nerve damage in a mouse model of multiple sclerosis (MS), a study reported. IndCl may help to improve vision in people with the disease, but…

Multiple sclerosis (MS)-associated inflammation in the cerebral cortex — the outermost layer of the brain that is involved in cognitive function — prompts the destruction of neural connections by specific immune cells, according to a study in a mouse model of MS. These immune cells targeted dendritic spines (nerve…

Innodem Neurosciences received $6 million to advance its digital biomarker eye-tracking technology as a possible way of diagnosing and monitoring neurodegenerative diseases. The technology is now being tested in people with multiple sclerosis (MS). Money raised by the Montreal-based startup came through a series A financing round led by Morningside Ventures.

A new primate model uncovered by researchers can help scientists understand the immune and inflammatory processes underlying the development of multiple sclerosis (MS) in humans, a study reports. It was already known that Japanese macaques — also called snow monkeys — can spontaneously develop encephalomyelitis (JME), a disorder that…

A thyroid hormone-mimicking compound not only prevented nerve cell damage but promoted the cells’ survival in a mouse model of multiple sclerosis (MS). This discovery advances previous research showing that the compound, called sobetirome, can induce the repair of myelin, the protective sheath around nerves. The data suggest…

Scientists at the UCLA Broad Stem Cell Research Center have developed a technique able to more efficiently isolate specific T-cells — immune cells involved not only in the fight against infections and cancer but also in autoimmune diseases such as multiple sclerosis (MS) — for research. In particular, the…

Imatinib, a cancer treatment, stopped an injury response mechanism of the central nervous system (CNS) from activating, damage to which is a hallmark of multiple sclerosis (MS), an early study reported. Treatment with imatinib lessened immune cell infiltration and eased disease progression in mouse models of MS. Study researchers…

CXCL13, an inflammatory biomarker, may be a good marker of likely future disease activity in people with multiple sclerosis (MS), a study suggests. The study, “Intrathecally produced CXCL13: A predictive biomarker in multiple sclerosis,” was published in the Multiple Sclerosis Journal – Experimental, Translational and Clinical. Clinicians caring…

Levels of myelin sheath components called ceramides are altered in the blood of people with multiple sclerosis (MS) and may be linked with retinal degeneration and physical disability, a study has found.  Specific ceramides were altered only in those with progressive…

New research in mice suggests that poor recycling of cholesterol in the brain impairs the repair of myelin, the protective coat surrounding nerve cells that is lost in multiple sclerosis (MS). Pharmacological stimulation of cholesterol synthesis by brain immune cells — called microglia — boosted the regeneration of myelin,…

The prevalence of primary headaches — those with no clear cause — is high among patients with multiple sclerosis (MS), a new study suggests. Clinical screening of headache among MS patients could help tailor individualized treatments and ease the impact of the disease for these patients. The study, “…

The levels of a protein called Neuregulin-1 beta 1 (Nrg-1beta1) decline with the onset and progression of multiple sclerosis (MS), a new study suggests. The findings support the potential of Nrg-1beta1 as a predictor of MS risk and progression and suggest that restoring its levels may help halt disease…

A new research project will seek to better understand the biological processes that drive memory problems in people with multiple sclerosis (MS), as a better understanding of these processes may open new avenues for intervention. The four-year study is titled “Neuroimaging of Hippocampally Mediated Memory Dysfunction in…

The pro-inflammatory environment characteristic of multiple sclerosis (MS) reduces the levels of PPAR-gamma — a receptor protein whose activation dampens inflammation — and impairs myelin processing in immune cells that clear myelin debris, a study suggests. These findings may help to better understand how PPAR-gamma regulates the function of these…

Exposure to stress before birth can worsen the clinical symptoms of multiple sclerosis (MS) during adulthood, a study in a mouse model of MS suggested. Investigators also found that prenatal stress can change the levels of a protein critical for neurological development, called…

A multiple sclerosis (MS)-specific computerized cognitive rehabilitation (CR) program led to significant improvements in mental skills among MS patients participating in a recent pilot study. These findings suggest that those with MS, and likely other disorders, might gain the greatest benefits from tailored cognitive tests that are specifically adapted…

The expansion of chronic white matter lesions in people with relapsing-remitting multiple sclerosis (RRMS) determined the increase in total lesion volume and significantly contributed to disease progression, a study has revealed. The study, “Expansion of chronic…

People with multiple sclerosis (MS) may have cognitive defects that cannot be detected using conventional paper-and-pen tests but that can be assessed with computer-based tests, a new study shows. The findings also indicate that people with MS may be more susceptible to cognitive impairment when the brain has to address increased…

A software platform, called CogniSoft, allows for automated assessments of cognitive health in people with multiple sclerosis (MS). The platform was described in the study “CogniSoft: A Platform for the Automation of Cognitive Assessment and Rehabilitation of Multiple Sclerosis,” published in the journal Computers. Cognitive impairment…

Scientists have created myelin-producing cells, called oligodendrocytes, from pluripotent stem cells derived from patients with multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) in just three weeks. They also demonstrated these lab-made oligodendrocytes were able to produce myelin — the fatty substance that normally wraps around neurons’…

Neurofilament Light Levels at First MS Event Can Predict Long-term Brain Atrophy Researchers are looking at a protein that’s released into the body’s fluids when neurons become damaged. They hope it will help them predict — as far as 10 years down the road from the first indication of…
