摘要

Protease-activated receptors (PARs) are a unique class of G protein-coupled receptors activated by proteolytic cleavage of the receptor N terminus. The exposed new N terminus acts as a tethered ligand that interacts with extracellular loop 2 of its receptor, resulting in the initiation of intracellular signaling. To date, four PAR subtypes (PAR1-4) have been reported; these are expressed in a variety of organs and have important functions both physiologically and pathologically.1,2 Activation of PARs is initiated by several serine proteases. PAR1 is activated by thrombin and PAR2 is activated by several serine proteases, including trypsin and mast cell tryptase. Recently, it was reported that PAR activation closely relates to sensory neuron-associated disorders, such as inflammation, pain and pruritus. Consequently, inhibitors of PAR signaling, including protease inhibitors, antagonists and intracellular signaling inhibitor, are expected to be therapeutic candidates for these disorders and biological tools.
