It is known that H(2)S causes neurogenic inflammation and elicits hyperalgesia. Here we show that H(2)S activates mouse transient receptor potential ankyrin 1 (TRPA1) channels and elicits acute pain, using TRPA1-gene deficient mice (TRPA1(-/-)) and heterologous expression system. In wild-type mouse sensory neurons, H(2)S increased the intracellular Ca(2+) concentration ([Ca(2+)](i)), which was inhibited by ruthenium red (a nonselective TRP channel blocker) and HC-030031 (a TRPA1 blocker). H(2)S-responsive neurons highly corresponded to TRPA1 agonist-sensitive ones. [Ca(2+)](i) responses to H(2)S were observed in neurons from transient receptor potential vanilloid 1 (TRPV1(-/-)) mice but not from TRPA1(-/-) mice. Heterologously expressed mouse TRPA1, but not mouse TRPV1, was activated by H(2)S. H(2)S-induced [Ca(2+)](i) responses were inhibited by dithiothreitol, a reducing agent. Analyses of the TRPA1 mutant channel revealed that two cysteine residues located in the N-terminal internal domain were responsible for the activation by H(2)S. Intraplantar injection of H(2)S into the mouse hind paw caused acute pain which was significantly less in TRPA1(-/-) mice. The [Ca(2+)](i) responses to H(2)S in sensory neurons and in heterologously expressed channels, and pain-related behavior induced by H(2)S were enhanced under acidic conditions. These results suggest that H(2)S functions as a nociceptive messenger through the activation of TRPA1 channels. TRPA1 may be a therapeutic target for H(2)S-related algesic action, especially under inflammatory conditions."xsd:string |
