Our results suggest that TRPA1 acts as a molecular target for ET-1, and sensitization of TRPA1 through ET<sub>A</sub>R-PKA pathway contributes to ET-1-induced mechanical hyperalgesia.
Role of ET(A) and ET(B) endothelin receptors on endothelin-1-induced potentiation of nociceptive and thermal hyperalgesic responses evoked by capsaicin in rats.
