AspirinBlocksSignalingPathwayInvolvedinPlateletActivation
Activation of the protease-activated GPCRs in platelets contributes to platelet activation in clotting. The protease-activated receptors PAR1 and PAR4 are cleaved by the protease thrombin, releasing a tethered peptide ligand that activates the receptor and triggers intracellular calcium release. Platelets from mice lacking the PAR4 gene are not activated by thrombin and are impaired in clotting, supporting the import......阅读全文
