Ca2+/Calmodulin Modulates TRPV1 Activation by Capsaicin
TRPV1 ion channels mediate the response to painful heat, extracellular acidosis, and capsaicin, the pungent extract from plants in the Capsicum family (hot chili peppers) (Szallasi, A., and P.M. Blumberg. 1999. Pharmacol. Rev. 51:159-212; Caterina, M.J., and D. Julius. 2001. Annu. Rev. Neurosci. 24:487-517). The convergence of these stimuli on TRPV1 channels expressed in peripheral sensory nerv...

متن کاملNovel methodology to identify TRPV1 antagonists independent of capsaicin activation.
TRPV1 was originally characterized as an integrator of various noxious stimuli such as capsaicin, heat, and protons. TRPV1-null mice exhibit a deficiency in sensing noxious heat stimuli, suggesting that TRPV1 is one of the main heat sensors on nociceptive primary afferent neurons and a candidate target for heat hypersensitivity in chronic pain. Several different potent and selective TRPV1 antag...
متن کاملIntegrating TRPV1 Receptor Function with Capsaicin Psychophysics
Capsaicin is a naturally occurring vanilloid that causes a hot, pungent sensation in the human oral cavity. This trigeminal stimulus activates TRPV1 receptors and stimulates an influx of cations into sensory cells. TRPV1 receptors function as homotetramers that also respond to heat, proinflammatory substances, lipoxygenase products, resiniferatoxin, endocannabinoids, protons, and peptide toxins...
متن کاملProton activation does not alter antagonist interaction with the capsaicin-binding pocket of TRPV1.
Vanilloid receptor 1 (TRPV1) is activated by chemical ligands (e.g., capsaicin and protons) and heat. In this study, we show that (2E)-3-[2-piperidin-1-yl-6-(trifluoromethyl)pyridin-3-yl]-N-quinolin-7-ylacrylamide (AMG6880), 5-chloro-6-[(3R)-3-methyl-4-[6-(trifluoromethyl)-4-(3,4,5-trifluorophenyl)-1H-benzimidazol-2-yl]piperazin-1-yl]pyridin-3-yl)methanol (AMG7472), and N-(4-tertiarybutylphenyl...
