Mechanisms of transient receptor potential vanilloid 1 activation and sensitization by allyl isothiocyanate.
Allyl isothiocyanate (AITC; aka, mustard oil) is a powerful irritant produced by Brassica plants as a defensive trait against herbivores and confers pungency to mustard and wasabi. AITC is widely used experimentally as an inducer of acute pain and neurogenic inflammation, which are largely mediated by the activation of nociceptive cation channels transient receptor potential ankyrin 1 and trans...
متن کاملCa2+/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 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 کاملLactate is a potent inhibitor of the capsaicin receptor TRPV1
Tissue ischemia results in an accumulation of lactate and local or systemic lactic acidosis. In nociceptive sensory neurons, lactate was reported to sensitize or activate the transient receptor potential ion channel TRPA1 and acid-sensing ion channels (ASICs). However, it is unclear how lactate modulates the TRPV1 regarded as the main sensor for acidosis in sensory neurons. In this study we inv...
