Data Sheet

Background: PAR-2 (protease-activated receptor 2) is a G-protein-coupled receptor activated by certain serine proteases such as trypsin and tryptase. It is widely distributed in the body in various tissues, and is involved in the alimentary, circulatory, respiratory and neuronal systems. In the gastric mucosa, PAR-2 modulates multiple functions and exerts mucosal cytoprotection mainly by activating sensory neurons. Thus, PAR-2 may be an important therapeutic target for treatment of gastric mucosal injury. Other research have shown PAR-2 to play an important role in vascular diseases. PAR2-derived peptide agonists have been shown to reduce vascular tone, and therefore increase blood flow. A mechanism for PAR2-mediated endothelial- dependent relaxation and hyperpolarization of vascular smooth muscle in select arterial vascular beds suggests a strategy for correction of endothelium-based vascular dysfunction. In diseases and conditions such as atherosclerosis or to injury, vascular tissue show variable changes of PAR-2 expression. PAR-2 agonists and antagonists may become leads for a new class of therapeutic agents for treatment of vascular diseases.
