Webor mitogenesis. Thrombin receptor and PAR-4 appear to account for most Thrombin signaling in platelets. Activation of PAR-2 in vitro is induced by trypsin, suggesting that PAR-2 is not an alternative Thrombin receptor. Cyto-kines including TNF-α and IL-1β increase PAR-2 expression, indicating PAR-2 involvement in the acute inflammatory response. WebAug 20, 2024 · Thrombin receptor (also designated protease-activated receptor-1 or PAR-1), PAR-2 and PAR-3 compose a distinct class of G protein-coupled receptors activated by proteolysis. Cleavage of these receptors by proteases occurs within the amino-terminal extracellular domain.

WebThrombi can cause tissue ischemia, and fibrin degradation products and activated platelets can enhance inflammation. In addition, coagulation proteases activate cells by cleavage of PARs (protease-activated receptors), including PAR1 and PAR2. WebDepicted centrally is the main thrombin receptor, PAR-1 which is activated when thrombin cleaves the N-terminal domain, unmasking a tethered ligand. PAR-1 activation leads to platelet activation and endothelial cell activation with exocytosis of Von Willebrand factor and P-selectin, which are critical steps in thrombosis and inflammation.
