Abstract
Atherosclerosis is a systemic inflammatory disease characterized by the accumulation of inflammatory cells in the intima of large arteries. The presence of platelets at the site of inflammation and endothelial injury has been known since the early 1960s. In the following years, it was generally accepted that rupture or erosion of advanced atherosclerotic lesions initiates platelet activation and aggregation on the thrombogenic surface of a disrupted atherosclerotic plaque. Thrombotic vascular occlusion is associated with ischaemic episodes in the retina, brain, heart, and other organs. While it is widely accepted that platelets play a significant role in thromboembotic events generated by atherosclerotic lesions (atherothrombosis), their involvement in the initiation of the atherosclerotic process has not been widely recognized by the scientific community. An expanding body of evidence on the role of platelets in the development of atherosclerotic lesions continues to build. Platelets bind to leukocytes and endothelial cells, and initiate the transformation of monocytes into macrophages. Additionally, platelets internalize oxidized phospholipids and promote foam cell formation, as well as recruit progenitor cells that are able to differentiate into foam or endothelial cells. In total, platelets play a key role in the initiation, development, and total extent of atherosclerotic lesions.
