Investigation of Activating signals Transmitted during Platelet Aggregation

Funded Activity Summary

The blood platelet is a specialized adhesive cell that plays a critical role in the normal blood clotting process through its ability to rapidly adhere to sites of vascular damage. Upon injury to a blood vessel, platelets undergo a number of internal signalling process and strucural changes that allow them to rapidly adhere to the area of damage. Following this initial adhesion process, platelet-platelet interactions occur leading to the development of a stable blood clot. Our research studies are aimed at understanding more closely the factors that regulate platelet-platelet interactions during the course of blood clot formation, since this is an important determinant not only of normal clot formation, but also in the development of harmful blood clots (thrombi) associated with the onset of diseases such as heart attack and stroke. Our particular focus is on the way in which platelets communicate to one another during the course of platelet thrombus development. Particulary, we are interested in the role of calcium as a signal mediating platelet-platelet communication. We believe that the transmission of these calcium signals may be the key signaling mediator of blood clot formation and normal haemostasis.
