platelet glycoprotein receptors

Platelet glycoprotein receptors are specialized proteins on the surface of blood cells called platelets, which play a key role in blood clotting. These receptors identify and bind to other molecules, allowing platelets to stick together and to injured blood vessels, forming a clot to stop bleeding. Different glycoproteins, such as GPIIb/IIIa and GPIb-IX-V, recognize specific partners like fibrinogen and von Willebrand factor. This complex system ensures a quick and accurate response to vascular injury, maintaining blood flow and preventing excessive bleeding while avoiding abnormal clot formation.
