Trpv1 in pain and itch
WebDifferent acute pain states and itch were found to be transmitted in TRPV1 neurons. TRPV1 channels are activated by intracellular long-chain acyl CoAs; TRPV1 protein channel is involved in cigarette smoke-induced ATP release in the lung. TRPV1-immunoreactive nerve fibers and NGF have a role in inflammation in interstitial cystitis/bladder pain ... WebInterestingly, topical delivery of the TRPV1 agonist capsaicin to human skin initially elicited a sensation of itch followed by burning pain 27, and topical application of menthol elicited itch in some subjects 20, suggesting that some TRP channel agonists initially activate pruriceptors followed later by nociceptors.
