Activation of platelets and the subsequent aggregation of platelets has a crucial role maintaining normal haemostasis. Disturbance in this system can lead to cerebrovascular, cardiovascular and peripheral vascular diseases where it can lead to a stroke, unstable angina and myocardial infarction. When a vessel is damaged ADP is released from damaged cells and activated platelets, inducing further platelet aggregation. WebJul 28, 2024 · In addition to the key role in hemostasis and thrombosis, platelets have also been wildly acknowledged as immune regulatory cells and involving in the pathogenesis of inflammation-related diseases.
