Thermoreceptor - tissue damage
WebbThermoreceptors primarily sensitive to cold have increased activity at temperatures cooler than the neutral skin temperature (about 34 °C [93 °F]), and thermoreceptors primarily … WebbAbstract: The transient receptor potential vanilloid 1 (TRPV1) is a thermoreceptor that responds to noxious temperatures, as well as to chemical agonists, such as vanilloids and protons. In addition, its channel activity is notably potentiated by proinflammatory mediators released upon tissue damage.
