Results raise prospects for tailoring treatments for patients with MS.
Animal studies by University of Michigan scientists suggest that people who experience the same clinical symptoms of multiple sclerosis (MS) may have different forms of the disease that require different kinds of treatment.
The results, if borne out in further studies, point to a time when doctors will be able to target specific inflammatory processes in the body and more effectively help MS patients, using available drugs and new ones in the pipeline. Since the 1990s, the treatment picture has brightened for people with multiple sclerosis in its most common form, relapsing-remitting MS. Beta interferon drugs and glatiramer acetate (marketed as Copaxone) have proved effective at decreasing the attack rate and suppressing inflammatory plaque development in many patients with MS. Yet why the drugs help some patients, but not others, has remained a mystery.
The U-M research team conducted the studies in mice that have a disease similar to MS: experimental autoimmune encephalomyelitis or EAE. The team found that different inflammatory chemicals, whose activity is linked to two different types of immune system T cells, could bring on the same paralysis and other MS-like signs. They also showed that drugs that block one of the inflammation pathways were not effective at blocking the other. The results, published online ahead of print, will appear in the July 7 issue of the Journal of Experimental Medicine...................
