Itaconate, a common metabolite, shows promise in MS mouse model

Itaconate, a metabolite produced during cellular energy production activities, was found to restore the balance of immune T cells and reduce multiple sclerosis (MS) symptoms in a mouse model of the disease, a study reported. The common metabolite specifically suppressed the production of pro-inflammatory T cells while promoting the…

TRE-515 Appears to Block Immune Cell Attacks in Mouse Study

An experimental oral therapy called TRE-515 significantly reduced disease severity and the growth of the abnormal immune cells that drive multiple sclerosis (MS) in two mouse models of the disease, a study found. Notably, the efficacy of Trethera Corp.’s potential treatment, administered either in a preventive or therapeutic…

Astrocytes May Promote MS Inflammation via D2 Receptors

A set of receptors involved in dopamine signaling may play a key role in the activation of astrocytes, nerve support cells that contribute to the inflammation that drives multiple sclerosis (MS), according to a study in a mouse model of the neurodegenerative disease. Mice lacking these receptors — called dopamine…

Heart Medication Digoxin Helps With Remyelination in Early Study

Digoxin, an approved medication for certain heart conditions, promoted the repair of myelin — the protective sheath around nerve fibers that is progressively lost in multiple sclerosis — in mouse models of the disease, a study reports. Combining digoxin with an experimental immune-modulating therapy was more effective at promoting myelin…

Targeting Ion Channel Piezo1 in T-cells Eased MS in Mice

Removing an ion channel called Piezo1 from immune T-cells lessened disease severity in a mouse model of multiple sclerosis (MS), a study showed. Notably, these beneficial effects were associated with an expansion of regulatory T-cells (Tregs) — a type of immune cell that typically dampens immune and inflammatory responses —…

Male Immune Cells Drive More Severe MS, Study Suggests

Due to differences in sex chromosomes, certain immune cells cause more severe disease in males than females, according to a new study in a mouse model of multiple sclerosis (MS). The findings could help to explain why biological males with MS tend to have more severe disease. The study,…

SERPINA3 Nerve Injury-induced Protein May Be Biomarker of PPMS

People with primary progressive multiple sclerosis (PPMS) have significantly higher levels of a nerve injury-induced protein, called SERPINA3, in the cerebrospinal fluid (CSF) than do those with relapsing-remitting MS (RRMS) and those without the neurodegenerative disease, a study shows. Of note, the CSF is the liquid that bathes…
