Platelet-endothelial interactions in atherosclerosis.

The pathogenesis of atherosclerosis, the leading cause of morbidity and mortality in the United States, is multifactorial. Many factors that have been shown to influence the development of atherosclerosis also affect the function of the endothelium through soluble or cell-cell interactions. Among these, interactions between platelets and endothelial cells have only recently begun to receive systematic study. This article reviews recent evidence showing how the interaction between platelets and endothelial cells may play a important role in the pathogenesis of atherosclerosis, suggesting an underappreciated potential locus for pharmacologic intervention.
