Nanotherapy Reduces Plaque Buildup

A drug-coated nanoparticle reduces plaque buildup in mouse arteries without causing harmful side effects, researchers have found.

Atherosclerosis, the accumulation of plaque inside artery walls, can lead to heart attacks and strokes. It’s the world’s No. 1 killer. Available therapies treat risk factors such as high blood pressure and high cholesterol but fail to address the accumulation of diseased cells and inflammation within artery walls.

This is precision medicine,” said Nicholas Leeper, MD, professor of vascular surgery and cardiovascular medicine. “We used the nanotubes to deliver a payload like a Trojan horse.”

Leeper, who sees patients at Stanford Health Care’s vascular and endovascular care clinic, is a senior author of a paper about the research that was published Jan. 27 in Nature Nanotechnology. The other senior author is Bryan Smith, PhD, a former visiting associate professor at the School of Medicine. He is now an associate professor of biomedical engineering at Michigan State University.
