Multiple Ca(2+)-dependent processes are involved in capsaicin-induced desensitization of transient receptor potential vanilloid 1 (TRPV1), but desensitization of TRPV1 by heat occurs even in the absence of extracellular Ca(2+), although the mechanisms are unknown. In this study, we tested the hypothesis that capsaicin and heat desensitize TRPV1 through(More)
TRPV1 is a nociceptive ion channel activated by polymodal stimuli such as capsaicin, proton, and noxious heat. Multiple inflammatory mediators activate protein kinases, especially protein kinase C (PKC), which phosphorylates TRPV1. Emerging evidence suggests that phosphorylation of TRPV1 constitutes specific signals underpinning pathological nociception.(More)
UNLABELLED Elevated glutamate levels within injured muscle play important roles in muscle pain and hyperalgesia. In this study, we hypothesized that protein kinase C (PKC)-dependent TRPV1 phosphorylation contributes to the muscle mechanical hyperalgesia following activation of Group I metabotropic glutamate receptors (mGlu1/5). Mechanical hyperalgesia(More)
