Built-in bypass bolstered by key molecule
UNC-CHAPEL HILL(US)—An abundance of tiny specialized blood vessels, called collaterals, can reduce damage caused by a blocked artery—such as stroke, heart attack, or leg injury—by enlarging to create a natural bypass. Research shows that this ability is related to levels of nitric oxide, a key signaling molecule. (more…)

Cholesterol crystals form early in heart disease
MICHIGAN STATE (US)—Cholesterol crystals, known to be a catalyst for heart attacks and strokes, also cause cells to send out danger signals that can lead to the inflammation and hardening of arteries. (more…)

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.

Plaque buildup may be linked to stiffening arteries
CORNELL (US)—Joints are not the only parts of our body that stiffen as we age. Our blood vessels do, too. In more than half of the U.S. population over 65, this stiffening of the blood vessels is accompanied by a buildup of plaque inside arterial walls, known as atherosclerosis, which can increase the risk of a heart attack.
