Functional interactions between G protein-coupled receptors are poised to enhance neuronal sensitivity to neuromodulators and therapeutic drugs. Mu and delta opioid receptors (MORs and DORs) can interact when overexpressed in the same cells. but whether co-expression of endogenous MORs and DORs in neurons leads to functional interactions is unclear.
