Researchers discover new culprit in atherosclerosis

from plaques.

In the study researchers used a florescent tracking technique to label and monitor the movement of macrophage cells in and out of plaques. This experiment showed how macrophages were immobilized and retained in plaque by netrin-1 expression and also demonstrated macrophage emigration from plaque after the deletion of netrin-1.

"Our study identifies netrin-1 as a novel target for future therapeutic intervention for the treatment of atherosclerosis and cardiovascular disease," said Janine M. van Gils, PhD, lead author of the study and a post-doctoral researcher in the Marc and Ruti Bell Vascular Biology and Disease Program, Leon H. Charney Division of Cardiology, Department of Medicine at NYU Langone Medical Center. "This discovery provides new clues to help reduce the amount of plaque in arteries and the threat of atherosclerosis, a major cause of mortality in Western countries. The development of a new strategy to diminish macrophage accumulation in plaque offers great promise to reducing the occurrence of fatal cardiac events."
