Mapping the biology of drug-resistant multiple sclerosis

People suffering from multiple sclerosis have relied on a drug called interferon-beta to prevent flare-ups of the disease and avoid its crippling neurological symptoms. But interferon-beta treatment has its downsides: the drug is expensive, it can cause flu-like side-effects, and for up to half of patients, it simply doesn’t work. New research may point to alternative treatments for MS, report scientists.
