TRPV3
{{Short description|Protein-coding gene in humans}}
{{Infobox_gene}}
Transient receptor potential cation channel, subfamily V, member 3, also known as TRPV3, is a human gene encoding the protein of the same name.
The TRPV3 protein belongs to a family of nonselective cation channels that function in a variety of processes, including temperature sensation and vasoregulation. The thermosensitive members of this family are expressed in subsets of human sensory neurons that terminate in the skin, and are activated at distinct physiological temperatures. This channel is activated at temperatures between 22 and 40 degrees C. The gene lies in close proximity to another family member (TRPV1) gene on chromosome 17, and the two encoded proteins are thought to associate with each other to form heteromeric channels.{{cite web | title = Entrez Gene: TRPV3 transient receptor potential cation channel, subfamily V, member 3| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=162514}}
Function
The TRPV3 channel has wide tissue expression that is especially high in the skin (keratinocytes) but also in the brain. It functions as a molecular sensor for innocuous warm temperatures.{{cite journal | vauthors = Peier AM, Reeve AJ, Andersson DA, Moqrich A, Earley TJ, Hergarden AC, Story GM, Colley S, Hogenesch JB, McIntyre P, Bevan S, Patapoutian A | display-authors = 6 | title = A heat-sensitive TRP channel expressed in keratinocytes | journal = Science | volume = 296 | issue = 5575 | pages = 2046–9 | date = June 2002 | pmid = 12016205 | doi = 10.1126/science.1073140 | bibcode = 2002Sci...296.2046P | s2cid = 6180133 | url = https://hal.science/hal-00311330 }} Mice lacking these protein are unable to sense elevated temperatures (>33 °C) but are able to sense cold and noxious heat.{{cite journal | vauthors = Moqrich A, Hwang SW, Earley TJ, Petrus MJ, Murray AN, Spencer KS, Andahazy M, Story GM, Patapoutian A | display-authors = 6 | title = Impaired thermosensation in mice lacking TRPV3, a heat and camphor sensor in the skin | journal = Science | volume = 307 | issue = 5714 | pages = 1468–72 | date = March 2005 | pmid = 15746429 | doi = 10.1126/science.1108609 | bibcode = 2005Sci...307.1468M | s2cid = 11504772 | url = https://hal.science/hal-00118759 }} In addition to thermosensation TRPV3 channels seem to play a role in hair growth because mutations in the TRPV3 gene cause hair loss in mice.{{cite journal | vauthors = Imura K, Yoshioka T, Hikita I, Tsukahara K, Hirasawa T, Higashino K, Gahara Y, Arimura A, Sakata T | display-authors = 6 | title = Influence of TRPV3 mutation on hair growth cycle in mice | journal = Biochemical and Biophysical Research Communications | volume = 363 | issue = 3 | pages = 479–83 | date = November 2007 | pmid = 17888882 | doi = 10.1016/j.bbrc.2007.08.170 }} The role of TRPV3 channels in the brain is unclear, but appears to play a role in mood regulation.{{cite news | title = Incense on the brain, by Ran Shapira, Haaretz| newspaper = Haaretz| url = http://www.haaretz.com/print-edition/features/incense-on-the-brain-1.248292}} The protective effects of the natural product, incensole acetate were partially mediated by TRPV3 channels.{{cite journal | vauthors = Moussaieff A, Yu J, Zhu H, Gattoni-Celli S, Shohami E, Kindy MS | title = Protective effects of incensole acetate on cerebral ischemic injury | journal = Brain Research | volume = 1443 | pages = 89–97 | date = March 2012 | pmid = 22284622 | pmc = 3294134 | doi = 10.1016/j.brainres.2012.01.001 }}
Modulation
The TRPV3 channel is directly activated by various natural compounds like carvacrol, thymol and eugenol.{{cite journal |vauthors=Xu H, Delling M, Jun JC, Clapham DE |title=Oregano, thyme and clove-derived flavors and skin sensitizers activate specific TRP channels |journal=Nat.

Resolvin E1 (RvE1), RvD2, and 17R-RvD1 (see resolvins) are metabolites of the omega 3 fatty acids, eicosapentaenoic acid (for RvE1) or docosahexaenoic acid (for RvD2 and 17R-RvD1). These metabolites are members of the specialized proresolving mediators (SPMs) class of metabolites that function to resolve diverse inflammatory reactions and diseases in animal models and, it is proposed, humans. These SPMs also dampen pain perception arising from various inflammation-based causes in animal models. The mechanism behind their pain-dampening effects involves the inhibition of TRPV3, probably (in at least certain cases) by an indirect effect wherein they activate other receptors located on neurons or nearby microglia or astrocytes. CMKLR1, GPR32, FPR2, and NMDA receptors have been proposed to be the receptors through which these SPMs operate to down-regulate TRPV3 and thereby pain perception.{{cite journal | vauthors = Qu Q, Xuan W, Fan GH | title = Roles of resolvins in the resolution of acute inflammation | journal = Cell Biology International | volume = 39 | issue = 1 | pages = 3–22 | year = 2015 | pmid = 25052386 | doi = 10.1002/cbin.10345 | s2cid = 10160642 }}{{cite journal | vauthors = Serhan CN, Chiang N, Dalli J, Levy BD | title = Lipid mediators in the resolution of inflammation | journal = Cold Spring Harbor Perspectives in Biology | volume = 7 | issue = 2 | pages = a016311 | year = 2015 | pmid = 25359497 | doi = 10.1101/cshperspect.a016311 | pmc=4315926}}{{cite journal | vauthors = Lim JY, Park CK, Hwang SW | title = Biological Roles of Resolvins and Related Substances in the Resolution of Pain | journal = BioMed Research International | volume = 2015 | pages = 830930 | year = 2015 | pmid = 26339646 | pmc = 4538417 | doi = 10.1155/2015/830930 | doi-access = free }}{{cite journal | vauthors = Ji RR, Xu ZZ, Strichartz G, Serhan CN | title = Emerging roles of resolvins in the resolution of inflammation and pain | journal = Trends in Neurosciences | volume = 34 | issue = 11 | pages = 599–609 | year = 2011 | pmid = 21963090 | pmc = 3200462 | doi = 10.1016/j.tins.2011.08.005 }}{{cite journal | vauthors = Serhan CN, Chiang N, Dalli J | title = The resolution code of acute inflammation: Novel pro-resolving lipid mediators in resolution | journal = Seminars in Immunology | volume = 27 | issue = 3 | pages = 200–15 | year = 2015 | pmid = 25857211 | pmc = 4515371 | doi = 10.1016/j.smim.2015.03.004 }}
