Discovery Of Tiny Protein-Activator Responsible For Brain Cell Damage In Huntington Disease

Johns Hopkins brain scientists have figured out why a faulty protein accumulates in cells everywhere in the bodies of people with Huntington's disease (HD), but only kills cells in the part of the brain that controls movement, causing negligible damage to tissues elsewhere. The answer, reported this week in Science, lies in one tiny protein called "Rhes" that's found only in the part of the brain that controls movement.
