Anti-analgesic effect of the mu/delta opioid receptor heteromer revealed by ligand-biased antagonism.
Delta (DOR) and mu opioid receptors (MOR) can complex as heteromers, conferring functional properties in agonist binding, signaling and trafficking that can differ markedly from their homomeric counterparts.Because of these differences, DOR/MOR heteromers may be a novel therapeutic target in the treatment of pain.However, there are currently no lig
