Thrombosis and atherosclerosis: regulatory role of interactions among blood components and endothelium.

Complex interactions among constituents of blood and components of the vessel wall are involved in the pathogenesis of atherosclerosis and its subsequent thrombotic complications. Alterations in the endothelium are central both to the slowly progressive process of atherogenesis and to the acute events leading to thrombotic occlusion. Recent data, obtained by systematic evaluation of chronologic events that occur in diet-induced atherosclerosis, have extended our understanding of interactive processes among endothelium, monocytes, platelets, vascular smooth muscle cells, and humoral hemostatic elements in atherogenesis.
