Endothelial microparticles and erectile dysfunction: an update / 中华男科学杂志

ABSTRACT

Microparticles are submicron vesicles shed from plasma membranes in response to cell activation, injury and/or apoptosis. Microparticles of various cellular origins, such as platelets, leukocytes, and endothelial cells, are found in the plasma of healthy subjects, and their amount increases under pathological conditions. Recent studies show that endothelial microparticles, a kind of envelope particles derived from endothelial cells, not only constitute a marker of endothelial dysfunction, but also play a major biological role in the diagnostic and therapeutic approaches to erectile dysfunction.
