摘要：
Proteinase-activated receptors (PARs) function as cell sensors for proteinases. Expression of PARs in immune cells suggests a role in innate immunity. PAR(1) mediates the cellular effects of thrombin and causes cytokine and chemokine production by endothelial cells and macrophages. Expression of PAR(1) on fibroblasts mediates the profibrogenic activity of thrombin and triggers extracellular matrix protein deposition. PAR(2) activation by trypsin, tryptase, and coagulation proteinases triggers both pro- and anti inflammatory activities by regulating monocyte recruitment/activation in inflamed tissues.
