Background :

PAR-2 belongs to a four member family of G protein-coupled receptors (PAR-1 to -4) that are activated as a result of proteolytic cleavage by certain serine proteases, hence their name. In this modality of activation, a specific proteinase cleaves the PAR receptor within a defined sequence in its extracellular N-terminal domain. This cleavage results in the creation of a new N-terminal sequence (tethered ligand), which subsequently binds to a site in the second extracellular loop of the same receptor. This binding results in the coupling of the receptor to G proteins and in the activation of several signal transduction pathways1-3 Different PARs are activated by different proteinases. Hence, PAR-1 is activated by thrombin as are PAR-3 and PAR-4, while PAR-2 is activated by trypsin1-3. PAR-2 can be also cleaved and activated by other proteinases such as tryptase, membrane-type serine protease 1, and proteinase 31-3 PAR-2-mediated intracellular signaling has not been clearly elucidated, but activators of PAR-2 induce generation of IP3 and mobilization of intracellular Ca2+. Activation of the ERK1/2 and NF-kB intracellular pathways following PAR-2 activation has been also described1-3 Tissue distribution of PAR-2 is wide with the highest expression levels found in pancreas, small intestine, liver and kidney. In addition, PAR-2 expression was observed in dorsal root ganglion neurons, smooth muscle cells and endothelial cells. The physiological role of PAR-2 is not yet clearly understood, however studies using PAR-2 knockout mice have suggested roles in the cardiovascular, pulmonary and gastrointestinal systems. Several studies suggest that PAR-2 plays a central role in inflammatory diseases and nociceptive pain transduction; hence PAR-2 blockers have been proposed to be useful in the therapeutic control of inflammation and pain1-3.
