abstract：:U46619 is a potent platelet agonist, its binding to the thromboxane A2 receptor resulting in Gq-binding protein-mediated responses; nevertheless, it is unable to cause platelet aggregation, unless released ADP is present. In this study we demonstrate that Gi activation is the step U46619 lacks to cause platelet aggreg...
