Figure 1. Schematics of activation, regulation and functions of transient receptor potential vanilloid subtype 3 (TRPV3) in keratinocytes.
Chemical and thermal agonists activate TRPV3 in keratinocytes. G-protein coupled receptors (GPCR), receptor tyrosine kinase (RTK), and other intracellular factors modulate the functions of TRPV3. TRPV3 activation induces the release of potential signaling molecules such as prostaglandins and cytokines.
