WebJan 17, 2024 · The capsaicin receptor TRPV1 is activated by noxious temperatures, however, acute heat pain is only marginally affected in mice after TRPV1 knockout but completely eliminated in mice lacking TRPV1 positive fibers. Exploring contribution of candidate signal transduction mechanisms to heat pain in humans needs translational … WebFeb 15, 2024 · The molecular mechanism of TRPV1 in heat and UV-induced MMP-1 expression in skin aging. Heat and UV light not only activate TRPV1 but also increase its expression. Heat and UV induce MMP-1 expression via Ca 2+ influx, PKC signaling and calcineurin/NFATc1 signaling. This scheme demonstrates the role of TRPV1 in skin aging …
