MS lesions

People with secondary progressive multiple sclerosis (SPMS) have more microscopic damage in normal-appearing brain tissue than do patients with relapsing-remitting multiple sclerosis (RRMS), according to a new imaging study. These patients also have a greater number of chronic active lesions than those with RRMS. “Using advanced diffusion MRI…

Abnormalities in the auditory and vestibular systems, which control hearing and balance, are frequently reported among people with multiple sclerosis (MS), a new study found. However, there is a substantial amount of variability in scientific studies that assess these abnormalities, making it difficult to draw an overarching conclusion about…

The protective barrier that prevents cells and large molecules from crossing into the central nervous system (CNS) is known to be unusually “leaky” in multiple sclerosis (MS), but targeting a protein called ARF6 can help to stabilize this barrier, a study in mouse models of MS found. Such a treatment…

People who had infectious mononucleosis — a contagious disease for which the Epstein-Barr virus (EBV) is the leading cause — had a higher incidence of multiple sclerosis (MS) in the 10 years following diagnosis compared with individuals not diagnosed with the virus, a study found. This link was particularly…

The U.S. Food and Drug Administration (FDA) has granted orphan drug designation to Trethera Corporation’s experimental oral therapy TRE-515 for demyelinating optic neuritis, an eye condition that may progress to multiple sclerosis (MS) or occur during the disease course. The first-in-class therapy is expected to lessen the inflammation…

A set of receptors involved in dopamine signaling may play a key role in the activation of astrocytes, nerve support cells that contribute to the inflammation that drives multiple sclerosis (MS), according to a study in a mouse model of the neurodegenerative disease. Mice lacking these receptors — called dopamine…

Calyx and Qynapse have joined forces to expand the use of artificial intelligence (AI)-based neuroimaging tools in clinical trials of treatment candidates for conditions affecting the central nervous system (CNS), or the brain and spinal cord.

Rune Labs has partnered with Coastal Research Institute (CRI) to identify new and noninvasive biomarkers of the loss of myelin, the fatty sheath surrounding nerve fibers that is progressively damaged by multiple sclerosis (MS). The collaboration involves a patient study that will take advantage of Rune Labs’…

The presence of iron rim lesions (IRLs), which are regions of chronic nervous system damage with ongoing inflammation, visible on MRI scans, is linked with more substantial disability in people with multiple sclerosis (MS), according to a new study. However, the connection between these lesions and worse disability does not…

An MRI technique called quantitative susceptibility mapping (QSM) can be used to accurately identify remyelinated brain lesions in people with multiple sclerosis (MS), a research team has discovered. Remyelinated lesions are those in which the myelin sheath — the protective coating around nerve fibers that is progressively lost…

Taking the pregnancy hormone estriol in combination with Copaxone (glatiramer acetate) significantly reduced the blood levels of neurofilament light chain (NfL) — a marker of nerve damage — in women with relapsing-remitting multiple sclerosis (RRMS), clinical trial data show. These lower NfL levels were significantly associated with a…

OM1 has created an artificial intelligence (AI)-based algorithm to estimate scores on the expanded disability status scale (EDSS), an established method for evaluating disability and disease progression in people with multiple sclerosis (MS). The algorithm, using a method called machine learning, was trained to estimate EDSS scores…

Proteins called tenascins block the regeneration of myelin by modulating the activity of oligodendrocytes, myelin-making cells of the central nervous system, a study in mouse models indicates. “Our research results open up new therapeutic approaches for the treatment of demyelinating diseases such as multiple sclerosis,” Juliane Bauch, a researcher at Ruhr-University…

Vidofludimus Calcium Safely Reduced RRMS Brain Lesions Vidofludimus calcium, also called IMU-838, is an oral therapy designed to reduce the activity of B- and T-cells. These are immune cells believed to be responsible for the inflammation that results in MS damage. In this small study, active lesions — including…

Treatment with the experimental immune-modulating therapy vidofludimus calcium reduced disease activity on MRI scans in adults with relapsing-remitting multiple sclerosis (RRMS), data from the Phase 2 EMPhASIS clinical trial shows. Top-line results from EMPhASIS were reported by the therapy’s developer Immunic Therapeutics in 2020. Researchers at…

A new tool called signal detection theory (SDT) found a relationship between subjective cognitive fatigue, often experienced by people with multiple sclerosis (MS), and the activation of certain brain regions, a study reported. Although the relationship was found in both patients and healthy controls after cognitive fatigue was…

Higher numbers of immune cells circulating in the bloodstream may mean a greater likelihood of developing multiple sclerosis (MS), according to a study based on a large pool of genetic data in people of European ancestry. One particular type of immune cell, called natural killer (NK) cells, was linked…

A protein called nephronectin mediates autoimmunity in a mouse model of multiple sclerosis (MS), and blocking this protein was found to prevent disease progression and processes that drive T-cells toward an inflammatory state, researchers reported. Study findings support nephronectin, a protein involved in kidney development, as a promising treatment…

A blood biomarker test developed by Octave can effectively monitor overall disease activity in people with multiple sclerosis (MS), helping to improve the care being given, the company reported. The assay, dubbed the MS Disease Activity (MSDA) test, can also be used to monitor disease activity across…

A new scoring system might more precisely evaluate disease development, severity, and treatment response in a commonly used mouse model of multiple sclerosis (MS) known as the experimental autoimmune encephalomyelitis or EAE model, scientists report. This scoring system, called “I AM D EAE,” was described in the study, “…

Among multiple sclerosis (MS) patients starting on Lemtrada (alemtuzumab), an early decrease in the leakiness of the blood-brain barrier (BBB) is associated with a lower likelihood of disease activity after two years, according to a new study. The blood-brain barrier is a cellular divisor that regulates which substances…

People with multiple sclerosis (MS) are more likely to have lesions in three regions of the brain — the anterior temporal horn, periventricular region, and cerebellar hemisphere — compared with people with other inflammatory brain diseases, a study reports. Looking for lesions in these parts of the brain may…
