WebDec 12, 2024 · Studies have shown that TRPV1 displays tonic activity at body temperature 13,14. The up-regulation of TRPV1 may lead to spontaneous activity in corneal TRPM8 + … Antagonists block TRPV1 activity, thus reducing pain. Identified antagonists include the competitive antagonist capsazepine and the non-competitive antagonist ruthenium red. These agents could be useful when applied systemically. Numerous TRPV1 antagonists have been developed by pharmaceutical companies. TRPV1 antagonists have shown efficacy in reducing nociception from inflammatory and neuropathic pain models in rats.

WebSep 30, 2024 · This suggests that TRPV1 also regulates FAAH expression. It is known that low doses of endocannabinoids, such as AEA, activate CB1, which can subsequently excite or inhibit TRPV1 activity depending on the second messenger pathway activated (23, 59). However, at high concentrations, AEA can also directly activate TRPV1 . This direct … WebTRPV1 receptors are also found in muscles, joints, the urinary bladder and kidneys.
