Endothelial activation

Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis, among others. It is also implicated in the formation of deep vein thrombosis. As a result of activation, enthothelium releases Weibel–Palade bodies.
