The Transient receptor potential vanilloid 1 or TRPV1 can refer to the TPR cation channel receptor or the gene which encodes it in Homo sapiens.
TRPV1 is a nonselective ligand-gated cation channel that may be activated by a wide variety of exogenous and endogenous stimuli, including heat greater than 43°C, low pH, anandamide, N-arachidonoyl-dopamine, and capsaicin. TRPV1 receptors are found in the central nervous system and the peripheral nervous system and are involved in the transmission and modulation of pain, as well as the integration of diverse painful stimuli. [1].[2]
Additional recommended knowledge
Clinical significance
Novel TRPV1 antagonists have shown efficacy in reducing nociception from inflammatory and neuropathic pain models in rats. This provides evidence that TRPV1 is the capsaicin's sole receptor.[3]
In humans, drugs acting at TRPV1 receptors could potentially be used to treat neuropathic pain associated with multiple sclerosis, chemotherapy, or amputation, as well as pain associated with the inflammatory response of damaged tissue, such as in osteoarthritis.
