WebFurthermore, both the N- and C-termini of TRPV1 have been implicated in thermosensation. Chimeras of TRPV1 and TRPM8 in which the C-termini were exchanged conferred heat sensitivity to TRPM8 and cold sensitivity to TRPV1, suggesting that the C-terminus is involved in the directionality of temperature sensation (Brauchi et al., 2006). WebSep 30, 2024 · Contrary to TRPV1, TRPV4, and TRPA1, TRPM8 activation may attenuate pain through suppression of TRPV1 activity and the inhibition of TRPA1 function [68,69].
