Inhibiting blood to save the brain

A fibrous protein called fibrinogen, found in circulating blood and important in blood clotting, can promote multiple sclerosis (MS) when it leaks from the blood into the brain, triggering inflammation that leads to MS-related nerve damage. Researchers at the University of California, San Diego (UCSD) School of Medicine have identified a fibrin-derived peptide that inhibits this specific inflammation process in mouse models of MS, reducing MS symptoms.
