WebPAR1, the major thrombin receptor in most cells, has important roles in several biological processes and can trigger distinct effects based on “biased” signalling . For instance, in cerebral ECs, thrombin activation of PAR1 induces a pro-inflammatory phenotype, resulting in increased expression of ICAM-1 [ 18 ] and also barrier disruption ... WebIt is the main thrombin receptor on human platelets and is the target of the FDA-approved drug vorapaxar. In contrast to human platelets, mouse platelets do not express PAR1 making them an excellent model to study platelet-independent effects of PAR1. PAR1 is activated by a variety of proteases. As with other GPCRs, PAR1 exhibits biased signaling.
