Non-proteolytic PAR-1 signaling may refine platelet activation models; leaves open clinical translation to antithrombotic strategies.
This study demonstrates that thrombin enhances arachidonic acid liberation in human platelets via a non-proteolytic interaction with PAR-1, providing mechanistic insights into platelet activation.
Akiba et al. (1999) studied this question. Thrombin vs. Trypsin or no thrombin was evaluated on Arachidonic acid liberation and Ca2+ mobilization. Thrombin accelerates cPLA2-catalyzed arachidonic acid liberation in human platelets through a non-proteolytic action toward PAR-1, independent of glycoprotein Ib.
