Splitting Sclerosis: by Nature Video

A new diagnostic test can tell whether beta-interferon — the major treatment for multiple sclerosis — will work for multiple sclerosis patients even before therapy begins. A team led by Larry Steinman, a neurologist at Stanford University, found the efficacy of the $25,000 per year drug depends on which type of immune cell is involved in the disease.
