Most patients with nonactive secondary progressive multiple sclerosis (SPMS) who took foralumab nasal spray for at least six months saw a decrease in microglial activity in their brains, according to its developer Tiziana Life Sciences. The results were gleaned from PET imaging data from 10 nonactive SPMS patients…

In multiple sclerosis (MS), lesions in the brain may start with small clusters of immune cells called microglia, a new study reveals. Scientists are working to understand exactly how these small clusters may develop into MS lesions, which they hope could uncover new targets for treating the disease.

Myrobalan Therapeutics has secured $24 million in series A financing to support the development of oral medications for multiple sclerosis (MS) and other diseases of the central nervous system (CNS), which comprises the brain and spinal cord. The company’s pipeline currently includes three candidate therapies…

Six of eight patients with nonactive secondary progressive multiple sclerosis (SPMS) being treated with foralumab nasal spray — all part of an intermediate-size expanded access program (EAP) allowing the therapy’s use — have experienced reductions in their fatigue levels. That’s according to treatment developer Tiziana Life Sciences,…

Six months of treatment with foralumab, administered into the nose, led to decreases in microglial activity in five of six people with nonactive secondary progressive multiple sclerosis (SPMS) involved in an expanded access program. Microglia are resident immune cells in the brain believed to play a role in driving…

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…

Certain cells in the eyes — specifically blood vessel cells and a type of neurological immune cell called microglia — exhibit high expression or activity of genes that have been linked to multiple sclerosis (MS), a new study reports.  The researchers also “identified…

Treatment with foralumab nasal spray resulted in marked clinical improvements after three months in the second secondary progressive multiple sclerosis (SPMS) patient treated under a single-patient access program. The findings were generally consistent with those seen in the first SPMS patient and supported a decision by the U.S. Food…

A medication currently approved to treat certain kinds of cancer, called topotecan, could be repurposed for treating neuroinflammatory conditions such as multiple sclerosis (MS) because it reduces the inflammatory activity of immune cells called microglia. That’s according to the study, “Myeloid cell-specific topoisomerase 1 inhibition using DNA origami…

The experimental therapy XPro1595 was found to promote remyelination — the repair of the myelin sheath — in a mouse model of myelin loss, new data show. Myelin, the fatty covering that helps nerve fibers send electrical signals, is damaged by the immune system in …

Treatment with hydroxychloroquine, an anti-malaria medication, appeared to help slow disability progression among people with primary-progressive multiple sclerosis (PPMS) in a small, proof-of-concept clinical trial. Hydroxychloroquine “is a promising treatment candidate for PPMS and should be investigated further in randomized controlled clinical trials,” its researchers wrote. Results of the study…

An interaction between immune cells and glia cells in the brain, mediated by the C1q complement system protein, appears to drive chronic inflammation in multiple sclerosis (MS), new research shows. Inhibiting this protein helped to resolve inflammation in mouse models of MS and in tissue cultures, its researchers found.

Researchers have identified a molecular switch that awakens stem cells in a specific region of the mouse brain — and with their activation, two new types of glia, non-neuronal cells that play critical roles in brain function, also were discovered. Notably, the development of these new glial cell types also…

A professor at the University of Freiburg, in Germany, was awarded the Novo Nordisk Prize for his research into the role of microglia in diseases such as multiple sclerosis (MS) and Alzheimer’s disease, and how they might be used as early warning signs of these disorders. Marco Prinz, MD,…

A gene called Mertk has important roles in the repair of myelin, the fatty substance that surrounds and protects neurons and that is lost in multiple sclerosis (MS). The findings were published in Cell Press, in the study “Multiple sclerosis risk gene Mertk is required for…

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…

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,…

Oral administration of trehalose — a sugar molecule found in plants and fungi and reported to have neuroprotective effects — eased symptoms and halted disease progression in a mouse model of multiple sclerosis (MS). These benefits were associated with a restoration of the ability of microglia (the brain’s immune cells) to break down…

Tolebrutinib (SAR442168), an investigational oral BTK inhibitor to treat relapsing forms of multiple sclerosis (MS), was seen to prevent the loss of myelin when given to a mouse model of demyelination in a preclinical study. The investigative therapy achieves this by preventing…

Roche has launched a Phase 3 clinical trial program to evaluate fenebrutinib, its investigational oral BTK inhibitor, in people with relapsing forms of multiple sclerosis (MS) and primary progressive MS (PPMS). Data on fenebrutinib’s potency and selectivity, as well as the design of the clinical…
