Funkcija уреди

Aktivacija delta receptora proizvodi analgeziju u manjoj meri nego aktivacija mu-opioidnih receptora.[2] Mnogi delta agonisti mogu takođe da uzrokuju epileptičke napade u visokim dozama, mada nemaju svi ovo svojstvo.[3]

Ligandi уреди

Do nedavno je veoma mali broj fizioloških agenasa za studiranje δ receptora bio dostupan. Kao posledica toga razumevanje njihove funkcije je znatno ograničenije nego što je to slučaj s drugim opioidnim receptorima za koje su selektivni ligandi bili dostupni.

Nekoliko selektivnih delta opioidnih agonista je dostupno. Među njima su peptidi DPDPE i deltorfin II, i ne-peptidni lekovi poput SNC-80,[4] i potentnijeg (+)-BW373U86,[5] i novijeg leka DPI-287, koji ne proizvodi probleme sa konvulzijama viđene kod ranijih agenasa,[6] i mešoviti mu/delta agonist DPI-3290, koji je mnogo potentniji analgetik nego visoko selektivni delta agonisti.[7] Selektivni antagonisti delta receptora su takođe dostupni. Među njima je najpoznatiji opijatni derivat naltrindol.[8]

Interakcije уреди

Za delta opioidni receptor je pokazano da integuje sa Beta-2 adrenergičkim receptorom,[10] arestin beta 1[11] i GPRASP1.[12]
