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…

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…

The anti-inflammatory medication VX-765, which is delivered through the nose (intranasal), was found to limit disease progression in a preclinical model of multiple sclerosis (MS) by blocking a protein called caspase-1. The medication helped prevent damage to brain cells in mice. Researchers from the University of…

The presence of a particular gut bacterium widely used in probiotics, called Lactobacillus reuteri (L. reuteri), was sufficient to increase disease severity in a mouse model of multiple sclerosis (MS), but only in genetically susceptible animals, a recent study shows. These findings highlight the complex interactions between…

The nutritional supplement NanoStilbene, developed by Therapeutic Solutions International, worked better to reduce neurological damage and disease symptoms in an animal model of multiple sclerosis (MS) than the market-leading MS therapy Copaxone, the company announced. NanoStilbene is composed of easily absorbed nano-particles of pterostilbene, a…

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…

Oral administration of N-acetylglucosamine (GlcNAc) — a natural simple sugar sold as a dietary supplement — prevents myelin degeneration and loss of motor function in a mouse model of multiple sclerosis (MS). Myelin, the protective sheath around nerve fibers that helps to speed transmission of signals between nerve cells, is damaged…

Changing the gut’s microbial community (microbiota) with antibiotics prevented the development of multiple sclerosis (MS), but not its progression after the disease was established, data from a mouse model of the disease show. These findings support evidence that microbiota manipulations affect inflammatory immune responses involved in MS development, but…

Eliminating SARM1, an enzyme that plays a key role in nerve cell degeneration, protects neurons in mice with experimental autoimmune encephalomyelitis (EAE), a condition that mimics the key pathological features of multiple sclerosis (MS) in humans. The preclinical findings were presented by researchers at Disarm Therapeutics in a…

Treatment with Mayzent (siponomod) may reduce myelin deterioration by lessening the accumulation of immune cells in brain meninges, and preventing the migration of pro-inflammatory lymphocytes into the brain, according to a study in a mouse model of multiple sclerosis (MS). The research, “A Mouse Model of…

Inactivation of S1PR2, a cell surface protein, helps improve clinical disability and reduce demyelination in a mouse model of experimental autoimmune encephalitis (EAE), a condition similar to multiple sclerosis (MS) in humans, a study shows. This finding suggests that therapies blocking S1PR2 could have the potential to treat MS. The…

A small synthetic molecule called TDP6 mimics a natural growth factor and promotes myelin regeneration in a mouse model of demyelination diseases such as multiple sclerosis (MS), a new study from Australia shows. TDP6 works by targeting a receptor at the surface of myelin-producing cells called oligodendrocytes. The study, “…

Non-psychoactive cannabidiol (CBD), one of the active compounds in medical cannabis, significantly reduced clinical signs of multiple sclerosis (MS)-like disease in an experimental autoimmune encephalomyelitis mouse model. Researchers found that CBD promoted the increase of inflammatory-suppressor cells called myeloid-derived suppressor cells. The findings were reported in the study “Cannabidiol Attenuates Experimental Autoimmune…

Vitamin D3 insufficiency increases multiple sclerosis (MS) susceptibility in a gene and sex-dependent manner, a mouse study suggests. The study with that finding, “Sex-Specific Gene-by-Vitamin D Interactions Regulate Susceptibility to Central Nervous System Autoimmunity,” by researchers at the University of Vermont, was published in the journal Frontiers in…

Activation of the immune response mediated by cells called microglia favors remyelination and myelin repair in multiple sclerosis (MS), according to a new Canadian study using mice. The research, “mCSF-Induced Microglial Activation Prevents Myelin Loss and Promotes Its Repair in a Mouse Model of Multiple Sclerosis,” was…

Subtle changes in myelin, the protective layer of nerve fibers, may be an early event in multiple sclerosis (MS) prior to the inflammatory reaction, a new University of Calgary study shows. The study, “Biochemically altered myelin triggers autoimmune demyelination,” was published in the journal Proceedings…

Inhibiting an enzyme responsible for turning genes on and off can reverse damage to the myelin sheath that protects nerve cells, improving limb function, a multiple sclerosis-related study in mice shows. The research, which involved mice with sciatic nerve damage rather than MS, was published in the journal Nature Medicine.

Scientists at the University of Maryland have developed an experimental treatment to control the immune system and recover movement in a paralyzed mouse model of multiple sclerosis (MS). The team presented its research April 2 during the 253rd National Meeting & Exposition of the American Chemical Society in San Francisco. In…

Using a small RNA molecule belonging to the family of microRNAs (miRs), scientists could restore myelin in nerve cells and improve limb function in mouse models of human multiple sclerosis (MS). The study, “miR-219 Cooperates with miR-338 in Myelination and Promotes Myelin Repair in the CNS,” was published in…

Researchers managed to retrain the immune system to ignore antigens that trigger an autoimmune reaction. This approach alleviated the symptoms of multiple sclerosis (MS) and type 1 diabetes in a mouse model.

Canadian researchers are testing mice to see if cannabinoid oil products — a common medical marijuana treatment — could help alleviate the neuropathic pain that often afflicts patients with multiple sclerosis (MS). The preclinical study, “Identifying the molecular mechanisms involved in supressing multiple sclerosis induced neuropathic pain following cannabinoid treatment in…

Researchers have tested a new compound called ST266 in a mouse model of multiple sclerosis (MS) and found that its anti-inflammatory properties prevent the loss of cells related to optic neuritis — a condition that leads to vision loss. The study, “Intranasal Delivery of a Novel Amnion Cell Secretome Prevents…

Researchers showed that it could be possible to treat and cure inflammatory diseases such as multiple sclerosis (MS) by injecting a single dose of biodegradable polymer particles containing myelin self-antigen into the lymph nodes.

Researchers at the University of Heidelberg, Germany, recently showed that peripheral blood cells loaded with a drug that resembles the myelin protein are able to inhibit harmful immune responses and prevent relapses in a mouse model of relapsing-remitting multiple sclerosis (MS). The findings were described in the study “…
