Single gene may trigger arterial hardening
“Most drugs used to treat atherosclerosis do so by reducing LDL cholesterol levels. Although this approach is highly successful, it has been a mystery for decades as to how LDL gets from the blood into the vessel wall to initiate atherosclerosis,” says William Sessa of the Yale School of Medicine. The Yale researchers have identified a single gene that, when active, seems to trigger atherosclerosis.
