Research progress in medicines on protease-activated receptor 2

Protease-activated receptor 2 (PAR2) is a member of protease-activated receptors (PARs). PAR2 distributed in tissues and cells (such as skin, airway epithelial cell, pancreas, etc.) has a broad biological effects, and is involved in pathogenesis of many diseases, such as mechanical pain, asthma, pain of pancreatic cancer, inflammation, pruritus, etc. Intervention of PAR2 will help us to identify the role of PAR2 in the mechanisms of diseases and in the development of new drugs. This article concentrates on the research progress of agonist, antagonist, and pepducin on PAR2.
