Abstract
Thrombin and adenosine diphosphate (ADP) are perhaps the two most important activators of platelet function (Stormorken, 1986). Both agents elicit a rapid “shape change” where platelet discoid shape is lest and pseudopodia are extended, followed by aggregation. Thrombin also induces massive granule secretion under a variety of conditions, while ADP is much less potent (Mustard et al., 1975). There is therefore considerable functional similarity for both agents and much research has been directed to understanding the biochemical basis for how they cause the initial events in signal transduction, leading to “shape change”, activation of the glycoprotein IIb/Illa receptor with binding of fibrinogen, and resulting platelet aggregation.
