alpha-3 beta-4 nicotinic receptor
The alpha-3 beta-4 nicotinic receptor, also known as the α3β4 receptor and the ganglion-type nicotinic receptor,Pharmacology, (Rang, Dale, Ritter & Moore, {{ISBN|0-443-07145-4}}, 5th ed., Churchill Livingstone 2003) p. 138. is a type of nicotinic acetylcholine receptor, consisting of α3 and β4 subunits.{{cite journal | vauthors = Stauderman KA, Mahaffy LS, Akong M, Veliçelebi G, Chavez-Noriega LE, Crona JH, Johnson EC, Elliott KJ, Gillespie A, Reid RT, Adams P, Harpold MM, Corey-Naeve J | title = Characterization of human recombinant neuronal nicotinic acetylcholine receptor subunit combinations alpha2beta4, alpha3beta4 and alpha4beta4 stably expressed in HEK293 cells | journal = The Journal of Pharmacology and Experimental Therapeutics | volume = 284 | issue = 2 | pages = 777–89 | date = February 1998 | pmid = 9454827 | url = http://jpet.aspetjournals.org/cgi/pmidlookup?view=long&pmid=9454827 }}{{cite journal | vauthors = Xiao Y, Kellar KJ | title = The comparative pharmacology and up-regulation of rat neuronal nicotinic receptor subtype binding sites stably expressed in transfected mammalian cells | journal = The Journal of Pharmacology and Experimental Therapeutics | volume = 310 | issue = 1 | pages = 98–107 | date = July 2004 | pmid = 15016836 | doi = 10.1124/jpet.104.066787 | s2cid = 23900581 }} It is located in the autonomic ganglia{{cite journal | vauthors = Poth K, Nutter TJ, Cuevas J, Parker MJ, Adams DJ, Luetje CW | title = Heterogeneity of nicotinic receptor class and subunit mRNA expression among individual parasympathetic neurons from rat intracardiac ganglia | journal = The Journal of Neuroscience | volume = 17 | issue = 2 | pages = 586–96 | date = January 1997 | pmid = 8987781 | publisher = US National Library of Medicine | doi = 10.1523/JNEUROSCI.17-02-00586.1997 | pmc = 6573231 | doi-access = free }} and adrenal medulla,{{cite journal | vauthors = Gotti C, Clementi F, Fornari A, Gaimarri A, Guiducci S, Manfredi I, Moretti M, Pedrazzi P, Pucci L, Zoli M | title = Structural and functional diversity of native brain neuronal nicotinic receptors | journal = Biochemical Pharmacology | volume = 78 | issue = 7 | pages = 703–11 | date = October 2009 | pmid = 19481063 | doi = 10.1016/j.bcp.2009.05.024 | publisher = US National Library of Medicine | url = https://hal.archives-ouvertes.fr/hal-00509504/file/PEER_stage2_10.1016%252Fj.bcp.2009.05.024.pdf }} where activation yields post- and/or presynaptic excitation, mainly by increased Na+ and K+ permeability.
As with other nicotinic acetylcholine receptors, the α3β4 receptor is pentameric [(α3)m(β4)n where m + n = 5]. The exact subunit stoichiometry is not known and it is possible that more than one functional α3β4 receptor assembles in vivo with varying subunit stoichiometries.
Ligands which inhibit the α3β4 receptor have been shown to modulate drug-seeking behavior,{{cite journal |last1=HarringtonEtAl |first1=L. |title=Role of β4* Nicotinic Acetylcholine Receptors in the Habenulo–Interpeduncular Pathway in Nicotine Reinforcement in Mice |journal=Neuropsychopharmacology |date=2015 |volume=41 |issue=7 |pages=1790–1802 |doi=10.1038/npp.2015.346 |pmid=26585290 |pmc=4869047 }} making α3β4 a promising target for the development of novel antiaddictive agents.
