title: The antidepressant -like effects of delta-opioid receptor agonists.
abstract: Activation of the delta-opioid receptor (DOR) system produces an interesting behavioral profile distinct from that of other opioids. Unlike mu- and kappa-opioid agonists, delta-opioid agonists alone have limited pain-relieving qualities as measured in morphine-sensitive antinociceptive assays. Recent evidence, however, suggests that the DOR system may play a role in regulating mood and emotional states. For example, DOR activation stimulates robust antidepressant-like effects in preclinical assays, suggesting that these compounds may have therapeutic potential for treating human depression. This review discusses the role of the DORs in depression and the antidepressant-like effects of delta-opioid agonists as well as their limitations.
