CHARLOTTESVILLE, Va., Nov. 6, 2007 - Researchers at the University of Virginia Health System have identified an enzyme thought to be an important instigator of the inner-body conflict that causes Type 1 diabetes. A chronic condition that affects nearly three million American children and adults, Type 1 diabetes is more severe than Type 2. Type 1 diabetes, also called autoimmune diabetes, arises when the body’s infection-fighting white blood cells start destroying the beta-cells that produce insulin in the pancreas.
