Histaminski H₄ receptor je član familije G protein spregnutih receptora.^[1]^[2]^[3]

Distribucija u tkivu

H₄ je visoko izražen u koštanoj srži i belim krvnim zrncima. On reguliše otpuštanje neutrofila iz kičmene moždine i naknadnu infiltraciju u zimosanom indukovanom mišjem modelu zapaljenja plućne maramice.^[4] On je takođe izražen u crevima, jetri, plućima, slezini, testisima, timusu, krajnicima, i dušniku.^[5]

Funkcija

Pokazano je da H₄ posreduje hemotaksu mastocita.^[6] Smatra se da do toga dolazi putem mehanizma G_i spregnutog smanjenja cAMP.^[7]

Struktura

3D struktura H₄ receptora nije rešena usled problema vezanih za GPCR kristalizaciju. Razvijen je niz strukturnih modela H₄ receptora za različite svrhe. Prvi model H₄ receptora^[8] je formiran putem homolognog modelovanja baziranog na kristalnoj strukturi goveđeg rodopsina.^[9] Taj model je korišten za interpretaciju podataka mutageneze pojedinih mesta sekvence, čime je otkriven značaj Asp94 (3.32) i Glu182 (5.46) ostataka za vezivanje liganda i aktivaciju receptora.

Drugi strukturni model H₄ receptora baziran na rodopsinu je uspešno korišten za identifikaciju novih liganda.^[10]

Nedavni progres u GPCR kristalizaciji, posebno određivanje strukture ljudskog histaminskog H₁ receptora u kompleksu sa doksepinom^[11] će uticati na poboljšanje kvaliteta novih strukturnih modela H₄ receptora.

Terapeutski potencijal

Inhibicija H₄ receptora se može koristiti u tretiranju astme i alergije.^[7]

Visoko selektivni antagonist histaminskog H₄ receptora VUF-6002 je oralno aktivan i inhibira aktivnost mastocita i eozinofila in vivo.^[12] On ima antiinflamatorne i antihiperalgezivne efekte.^[13]
