5-HT1E receptor, (5-hidroksitriptaminski (serotoninski) 1E receptor, 5-HT_1E) je visoko izraženi humani G-protein spregnuti receptor^[1] koji pripada familiji 5-HT1 receptora (G_i-spregnutih serotoninskih receptora).^[2]^[3] Humani gen se označava sa HTR1E.^[4]

Funkcija

Funkcija 5-HT_1E receptora nije poznata usled nedostatka selektivnih farmakoloških oruđa, specifičnih antitela, i podobnih životinjskih modela.^[5] Gen 5-HT_1E receptora nema polimorfizama među ljudima (mali je broj mutacija), što je indikacija visokog nivoa evolucione konzervacije njegove genetičke sekvence, iz čega sledi da 5-HT_1E receptor ima važnu fiziološku ulogu kod ljudi.^[6] Pretpostavlja se da 5-HT_1E receptor učestvuje u regulaciji memorije kod ljudi, zbog zbog visoke zastupljenosti ovog receptora u frontalnom korteksu, hipokampusu, i bulbus olfactorius, što su integralni moždani regioni za regulaciju memorije.^[7]

Ovaj receptor je jedinstven među serotoninskim receptorima po tome što nije izražen kod glodarskih vrsta. Tim vrstama nedostaje gen koji kodira 5-HT_1E receptor. Međutim genomi svinje, rezus majmuna, i nekoliko lagomorfa (što obuhvata morsko prase i zeca) sadrže homologne 5-HT_1E gene.^[7] Morsko prase je najverovatniji kandidat za buduća ispitivanja funkcije 5-HT_1E receptor in vivo. Izražavanje 5-HT_1E receptora u mozgu morskog praseta je farmakološki potvrđeno. Obrasci izražavanja 5-HT_1E receptora u mozgu ljudi i morskog praseta su slični.^[5]

Selektivni ligandi

Visoko selektivni ligandi 5-HT_1E još uvek nisu dostupni. [³H]5-HT je jedini dostupni radioligand visokog afinita za 5-HT_1E receptor (5 nM).
