New Scale May Better Assess MS Changes, Therapy Response in Mice

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, “…

Cold Eases Inflammation, Disease Severity in MS Mouse Model

Colder ambient temperatures may ease the inflammation that drives multiple sclerosis (MS), early research in a mouse model suggests. Animals whose environment for two weeks was set at 10 C (about 50 F) had a “pronounced attenuation” of disease severity and other benefits compared with those kept at a…

Inflammatory Th17 Cells Seen to Trigger Obsessive Compulsive Disorder in MS Mouse Model

The pro-inflammatory Th17 cells that characterize multiple sclerosis (MS) may also underlie symptoms of obsessive-compulsive disorder (OCD), results of a mouse study show. The study, “Auto-Reactive Th17-Cells Trigger Obsessive-Compulsive-Disorder Like Behavior in Mice With Experimental Autoimmune Encephalomyelitis,” was published in the journal Frontiers in Immunology. “For the first time,…

Infection with Common Herpes Virus Speeds MS-like Disease Onset and Progression in Primate Model, Study Reports

Infection with the most common member of the herpes virus family, called HHV-6, may pass unnoticed and without symptoms, but the very act of being infected significantly accelerated the development and progression of a multiple sclerosis-like disease in nonhuman primates, a study reports. Its findings support the role of viral infection in…

Cannabidiol Increases Inflammatory Suppressor Cells, New MS Mouse Study Shows

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 MS Susceptibility in a Gene and Sex-dependent Manner

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…

Clomipramine, an Antidepressant, Shows Potential in Treating Progressive MS in Early Study

Clomipramine, an approved antidepressant, shows potential in treating people with progressive multiple sclerosis (MS)  — a disease form with few treatments — by protecting nerves from various processes thought to underly progressive MS, early research shows. The lab and animal study, which focused on already-approved treatments, was titled “Systematic…
