Histaminski H₃ receptori su izraženi u centralnom nervnom sistemu i u manjoj meri u perifernom nervnom sistemu, gde oni deluju kao autoreceptori u presinaptičkim histaminergičkim neuronima, i takođe kontrolišu promet histamina putem povratne inhibicije sinteze i oslobađanja.^[1] H₃ receptor takođe presinaptički inhibira otpuštanje brojnih drugih neurotransmitera (i.e. on deluje kao inhibitorni heteroreceptor) uključujući, ali verovatno ne samo dopamina, GABA, acetilholina, noradrenalina, i serotonina.

Genska sekvenca H₃ receptora je samo oko 22% i 20% homologna sa H₁ i H₂ receptorima respektivno.

Tkivna distribucija[uredi | uredi kod]

Funkcija[uredi | uredi kod]

Poput svih histaminskih receptora H₃ receptor je G protein spregnuti receptor. H₃ receptor je spregnut sa G_i G proteinom, tako da dovodi do inhibicije formiranja cAMP. Takođe, β i γ podjedinice interaguju sa N-tipom naponom kontrolisanog kalcijumskog kanala, da redukuju dejstvo potencijalom posredovanog uliva kalcijuma i tako redukuju otpuštanje neurotransmitera.

H₃ receptori funkcionišu kao presinaptički autoreceptori na histaminskim neuronima.^[2]

Raznovrsnost izražavanja H₃ receptora širom korteksa i podkorteksa je indikacija njegove sposobnosti da moduliše otpuštanje velikog broja neurotransmitera.

H₃ receptori učestvuju u kontroli sitosti.^[3]

Isoforme[uredi | uredi kod]

Postoji najmanje šest izoformi H₃ receptora kod ljudi, i više od 20 je otkriveno do sada računajući druge vrste.^[4] Kod pacova je do sad otkriveno šest podtipova H₃ receptora, dok su kod miševa poznate tri.^[5] Ti podtipovi imaju suptilne razlike u pogledu farmakologije (kao i distribucije, sudeći po istraživanjina na pacovima), ali njihove precizne fiziološke uloge nisu razjašnjene.

Farmakologija[uredi | uredi kod]

Histamin

Agonisti

Nisu poznati terapeutski proizvodi koji deluju kao selektivni agonisti za H₃ receptore. Postoji nekoliko jedinjenja koja se koriste kao istraživačka oruđa koja su u znatnoj meri selektivni agonisti. Neka od njih su:

(R)-α-metilhistamin
Cipralisant - Inicijalno istraživan kao H₃ antagonist, ali je kasnije utvrđeno da je agonist, pokazuje funkcionalnu selektivnost. Aktivira deo G protein spregnutih puteva^[6]
Imepip
Imetit
Imetridin
Metimepip
Proksifan

Antagonisti

Primeri antagonista su:^[7]

A-349,821^[8]
ABT-239
Betahistin
Burimamid (takođe slab H₂ antagonist)
Ciproksifan
Konesin
Klobenpropit (takođe H₄ antagonist)
Impentamin
Jodofenpropit
Tioperamid (takođe H₄ antagonist)
VUF-5681 (4-[3-(1H-Imidazol-4-il)propil]piperidin)

Terapeutski potencijal[uredi | uredi kod]

Ovaj receptor je predložen za biološki cilj u tretiranju poremećaja sna.^[9] Takođe se smatra da modulacija dejstva ovog receptora može da nađe primenu u tretmanu neuropatičkog bola.^[10]

Usled njegove sposobnosti modulacije drugih neurotransmitera, ligandi H₃ receptora se istražuju za lečenje brojnih neuroloških poremećaja, uključujući gojaznost (zbog interakcije histaminskog i oreksinskog sistema), poremećaja kretanja (zbog modulacije dopamina i GABA putem H₃ receptora u bazalnim ganglijama), šizofrenije i ADHD.^[11]

Istorija[uredi | uredi kod]

1983 - H₃ receptor je farmakološki identikovan.^[12]
1988 - Utvrđeno je da H₃ receptor posreduje inhibiciju otpuštanja serotonina moždanoj kori pacova.^[13]
1997 - Pokazano je da H₃ receptori modulišu ishemično otpuštanje norepinefrina kod životinja.^[14]
1999 - H₃ receptor je kloniran^[15]
2000 - H₃ receptori se nazivaju "novim kursom ishemije miokarda"^[16]
2002 - H₃^(-/-) miš (miš bez ovog receptora)^[17]
