    ..Thus, our data indicate that PI3K, together with the integrin outside-in signaling, play a central role in inducing the second wave of platelet secretion, which leads to the second wave of irreversible platelet aggregation. ..

    ..Therefore, while none of the antagonists, thus far developed for targeting TPRs, have made it into clinical use, this peculiar receptor can be antagonized by a large number of drugs used for indications unrelated to thrombosis. ..

    ..We conclude that TPr activation via PKC-?-mediated NAD(P)H oxidase activation increases both O(2)(·-) and ONOO(-), resulting in eNOS uncoupling in endothelial cells. ..

    ..These results suggest that the 12/15LO- and TxA(2) receptor-mediated pro-atherogenic effects are two distinct pathways and represent two separate therapeutic targets for a better anti-atherogenic strategy. ..

    ..The increased embolization in alpha2-null mice may argue against the use of alpha2beta1 integrin inhibitors for antithrombotic therapy. ..

    ..Increased responsiveness of TP receptors occurs in diabetic ApoE-KO mouse kidneys. Thus early changes in TP receptor-mediated vasoconstrictor activity may participate in the development of kidney disease in atherosclerosis and diabetes. ..

    ..Nascent LTC4 may activate platelets at a synapse with granulocytes before it is converted to LTD4, promoting mediator generation and the formation of leukocyte-platelet complexes that facilitate inflammation. ..

    ..TP ligands, including COX-1 (but not COX-2)-derived TxA2, promote initiation and early progression of atherogenesis in Apobec-1/LDLR DKOs but appear unimportant in the maintenance of established disease. ..
