The recognition that the restoration of patency to occludedblood vessels can improve clinical outcomes has led to intenseinterest in the formation and dissolution of platelet thrombiand in the pathobiologic features of vascular repair after aninjury. To study these events in an experimental model, manyinvestigators challenge isolated platelets or endothelium withstimuli that represent physiologic or pathologic mediators,such as thrombin or adenosine diphosphate (ADP), and find thatthese agonists cause the generation of intracellular mediatorsthat can markedly alter the function of each cell type. A criticalfacet of thrombus formation and vascular response to . . . [Full Text of this Article]
