Welcome to “MS News Notes,” a Monday morning 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: Testing a new MRI contrast agent One concern that some people with MS have when getting an MRI…

Nerve cells coated with myelin — the fatty substance that’s lost in multiple sclerosis (MS) — may be more vulnerable to degeneration in an inflammatory environment than cells lacking myelin, researchers working in MS patient tissues and mouse models report. The scientists believe the phenomenon arises when certain…

Welcome to “MS News Notes,” a Monday morning 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: MS experts offer more than 50 vaccine guidelines I know there are different opinions about vaccines, and I’ve…

Treatment with estriol, a hormone that’s produced during pregnancy, reduced disease severity and promoted myelin repair in the cortex — a key brain region affected in multiple sclerosis (MS) — in a mouse model of the disease. Those are the main findings of the study, “Neuroprotection in cerebral…

Welcome to “MS News Notes,” a Monday morning 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: Myelin repair and clemastine The Multiple Sclerosis News Today story “MRI method detects myelin repair with…

The over-the-counter antihistamine clemastine has demonstrated an ability to repair myelin, the protective coating on nerve fibers that’s damaged in multiple sclerosis (MS), according to an analysis of MRI data from the ReBUILD clinical trial. 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…

Microparticles that activate regulatory T-cells, or Tregs, an immune cell type with anti-inflammatory properties, reversed the accumulation of physical disability due to multiple sclerosis (MS) in a mouse model of the neurodegenerative disorder, a new study shows. Use of the novel strategy even cured some of the animals. “We…

A detailed examination of nerve tissue isolated from multiple sclerosis (MS) patients showed changes to the myelin sheath before the appearance of substantial inflammatory activity and lesions, a study reported. In MS patients, normal-appearing brain regions showed a less compact, detached, and disorganized myelin composition that may make…

When the immune system launches an attack to fight off infection with the Epstein-Barr virus, immune cells can accidentally end up targeting a protein called CRYAB that’s normally expressed by healthy myelin-making cells in the brain, a study found. The findings provide further evidence that molecular similarities between distinct…

Increased activation of microglia, the resident immune cells in the brain that contribute to chronic inflammation in multiple sclerosis (MS), is significantly associated with higher levels of neurofilament light chain (NfL) protein, indicating more nerve damage, a study found. Researchers particularly identified strong links between…

Modified nanocapsules containing retinoic acid can suppress inflammation and prompt the growth of cells that produce nerve fibers’ myelin coating, which is lost in multiple sclerosis (MS), a cell-based study shows. The results demonstrated how lipid (fat) nanocapsules that contain medicines can access the brain and treat the two…

A protein called Mfsd2a, which transports molecules that contain omega-3 fatty acids, is essential for regulating cells that make the fatty coating on nerve fibers, or myelin sheath, that’s damaged in multiple sclerosis (MS), a study indicates. In mice lacking Mfsd2a, the cells that make myelin, or oligodendrocytes, fail…

Attaching a kind of molecule backpack to myeloid cells — a type of immune cells involved in the inflammatory attack that drives multiple sclerosis (MS) — may help to halt inflammation and damage in the brain in MS by modulating immune cell activity, a study…

A newly developed laboratory model using tadpoles can help determine the remyelinating potential of new multiple sclerosis (MS) therapies via specific changes in behavior and vision tests, a new study suggests.
