The U.S. Food and Drug Administration has designated SetPoint Medical’s neurostimulator a breakthrough device for the treatment of relapsing-remitting multiple sclerosis (RRMS). This designation is intended to accelerate the development of devices intending to more effectively treat or diagnose life-threatening or chronically debilitating diseases than standard approaches.

Convelo Therapeutics is developing two experimental oral treatments to promote myelin repair in multiple sclerosis (MS) and both have shown promise in preclinical models. The company is in the final stages of safety studies in large animals. Once those studies are done, it plans to start studies that…
Supplements of indole 3-lactate (ILA), a molecule made by gut bacteria, significantly reduced disease severity and promoted myelin repair in mouse models of multiple sclerosis (MS). That’s according to new findings presented by Larissa Jank, PhD, a postdoctoral researcher at Johns Hopkins University, at the Americas Committee for Treatment…
In neurological inflammatory conditions like multiple sclerosis (MS), inflammatory immune cells may enter the brain through arachnoid cuff exit (ACE) points — newly discovered structures that normally seem to serve as a type of sewer system in the brain, helping to move out waste. Figuring out exactly how immune…
People in the early stages of multiple sclerosis (MS) who have more spontaneous myelin repair in the cortex — the outermost layer of the brain that’s critical for higher cognitive abilities — are less likely to experience worsening disability, a new analysis suggests. These findings have important implications for…
Problems with the workings of a protein called hnRNP A1 drives nerve death in multiple sclerosis (MS) by affecting how nerve cells process RNA, a study reports. RNA is an intermediary molecule that’s produced when genes are “read,” and it is used as a template for protein production. Abnormalities…
Junctions between nerve cells and certain cells called oligodendrocyte precursor cells, or OPCs, in the brain and spinal cord may play an important role in producing myelin, the protective substance that’s progressively lost in multiple sclerosis (MS), new research suggests. OPCs are abundant in the brain and spinal…
A novel compound that can lessen toxic overactivation of nerve cells was found to significantly reduce disease activity and restore lost myelin in two mouse models of multiple sclerosis (MS), a new study reports. Researchers say the compound, ZCAN262, may be a potential new treatment for MS should future…
The presence of damaged myelin — the fatty, protective substance surrounding nerve cells that’s lost in multiple sclerosis (MS) — may be more harmful to nerve cells than its removal altogether, according to new preclinical research. In mouse models of myelin-associated disease, a failure of microglia — the…
Targeting genes that control the daily activity cycle of cells that are responsible for repairing myelin in the brain and spinal cord may be a useful strategy for treating multiple sclerosis (MS), a new study shows. Findings also point to a potential link between myelin disorders such as MS…
In a surprise discovery, researchers found that deleting a protein called integrin alpha-3 blocked harmful immune cells from accessing the brain — and prevented the onset of symptoms — in a mouse model of multiple sclerosis (MS). Now, the researchers say that targeting this protein might be one way…
Infection with the Epstein-Barr virus (EBV) may prime the immune system to accidentally attack a brain protein called ANO2, new research shows. The findings may explain how EBV infection can lead to developing multiple sclerosis (MS), at least in some patients. Daniel Jons, PhD, a scientist at the…
The expression of a viral protein known as W-Env leads to the inflammatory activation of brain cells and impairs myelin repair in mouse models of multiple sclerosis (MS), a study reports. “Our study shows that the presence of W-Env in the brains of MS patients appears to generate a…
Note: This story was updated Sept. 15, 2023, to clarify ANK-700 was developed based on the preclinical work described in the study. An “inverse vaccine” that’s designed to teach the immune system not to attack a specific target, effectively reduced disease activity in mouse models of multiple sclerosis (MS),…
A protein called Daam2 helps to regulate the activity of cells in the brain that make myelin, the fatty covering around nerve fibers that’s damaged in multiple sclerosis (MS), a new study shows. By uncovering how that protein functions in the brain to boost myelin repair, researchers have discovered…
Four researchers working in multiple sclerosis (MS) were awarded incubator grants in MS Australia’s latest funding round, which they’ll use to kickstart projects designed to better understand the progressive neurodegenerative disease. Worth a total of AU$92,565, or roughly $60,000, this round of incubator grants provides seed funding…
A new system that can use MRI scans to effectively measure myelin content in brain tissue may help assess the progression of multiple sclerosis (MS) and evaluate the effectiveness of treatments. The technique was described in “Quantitative magnetic resonance mapping of the myelin bilayer,” which…
Treatment with polysialic acid, a sugar molecule naturally made in the body, may be a promising approach to boost myelin repair in people with multiple sclerosis (MS), according to a new study in lab-grown brain samples. Findings show that the molecule increased myelin repair, or remyelination, in the cell…
ASH41020, an investigational therapy from Ashvattha Therapeutics, significantly reduced disease severity and exhibited immunomodulatory properties in a mouse model of multiple sclerosis (MS), according to a recent presentation. Evidence indicated the therapy works by shifting the balance of immune cells called macrophages toward a less inflammatory and more…
Researchers have shed new light on the molecular mechanisms that help immune cells get into the brain to drive inflammation in multiple sclerosis (MS). Two proteins called MMP-9 and MMP-2 were found to break down some components of the barrier that keeps immune cells out of the brain, helping…
Delivering an antibody against the Nogo-A protein to a specific region of the nose called the olfactory mucosa improved motor function and preserved myelin in the spinal cord of a mouse model of multiple sclerosis (MS), according to a recent study. This intranasal mode of delivery enabled significant concentrations…
Welcome to “MS News Notes,” a column where I comment on multiple sclerosis (MS) news stories that caught my eye last week. Here’s a look at what’s been happening: Is it MS or something else? Should all autoimmune diseases that damage myelin be called MS? Probably not, according…
INmune Bio‘s experimental therapy XPro1595 may promote myelin restoration through the activation of two types of nervous system support cells, according to new data that may lead to novel treatment strategies for multiple sclerosis (MS) and other neurodegenerative disorders. The findings highlight the activation of microglia, key…

The changes in myelin were examined with a noninvasive MRI method that more…
Disease-associated inflammatory activity of microglia — a type of immune cell with a central role in the development of multiple sclerosis (MS) — is driven in part by molecular mechanisms that are activated when microglia try to clear the corpses of dead myelin-making cells. That’s according to a new…
