Insights into the platelet releasate
1Protein Mass Spectrometry lab, Department of Cell Biology, The Scripps Research Institute, La Jolla, California, USA.
Abstract:
The platelet releasate comprises of a multitude of inflammatory and vasoactive substances, which can attract atherogenic leukocytes from the circulation, activate endothelial cells and stimulate vessel growth and repair by triggering vascular cell proliferation, migration, and inflammation. Thus, platelets are believed central in the development and progression of atherosclerotic lesions and recent progress in uncovering more than 300 proteins in the thrombin-activated platelet releasate may advance our ability to understand the events involved and responses triggered in the progression of atherosclerosis. Furthermore, neutralisation of these platelet-derived pro-inflammatory factors may become an interesting means for therapeutic or preventative intervention in atherosclerosis.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
