ABSTRACT
Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel, located on cell membranes. TRPV3 is extensively expressed in various organs such as skin, brain, dorsal root ganglia, heart and colon. It's reported that TRPV3 involves in many physiological processes including sensation, skin barrier formation, hair growth and vasodilatation, and pathological processes like pruritus, cutaneous inflammatory disease and cancer. TRPV3 can respond to innoxious warm stimulation (≥ 33 ℃), endogenous substances (e.g., farnesylpyrophosphate) and exogenous small molecules (e.g., carvacrol, camphor and 2-APB). Recently, several natural or synthetic small molecules (e.g., osthole, 74a and dyclonine) have been shown to suppress TRPV3 activity, accompanying with therapeutic efficacy in animal models of diseases, which suggests the potential of TRPV3 as drug target. This paper reviews the research progress on the structure, physiological functions, related diseases and modulators of the TRPV3 channel to provide theoretical references for the future study on TRPV3 channel.
