Opioid Receptor Delta 1 (OPRd1)

The δ-opioid receptor is an opioid receptor that has enkephalins as their endogenous ligands.Activation of delta receptors produces some analgesia, although less than that of mu-opioid agonists. Many delta agonists may also cause seizures at high doses, although not all delta agonists produce this effect. Activation of delta receptors produces some analgesia, although less than that of mu-opioid agonists. Many delta agonists may also cause seizures at high doses, although not all delta agonists produce this effect. Until comparatively recently, there were few pharmacological tools for the study of δ receptors. Activation of δ receptors produces some analgesia, although less than that of mu-opioid agonists. Many δ agonists may also cause seizures at high doses, although not all δ agonists produce this effect.
