What are platelets coated in? Coated platelets, formed by collagen and thrombin activation, have been characterized in different ways: i) by the formation of a protein coat of α-granular proteins; ii) by exposure of procoagulant phosphatidylserine; or iii) by high fibrinogen binding.
What chemicals activate platelets? Thrombin is the most strong platelet agonist and also responsible for converting fibrinogen into fibrin to stabilize the platelet plugs [5, 6, 9, 13]. Thrombin activates platelets through protease-activated receptors (PAR) on the platelet surface via GPCR.
