The study has shown that activation of delta1-opioid receptors by a highly selective peptide agonist DPDPE (100 µg/kg) results in a significant increase of the immune response to antigen (SRBC, 5×108) in CBA mice. SCH-23390 (1 mg/kg), a selective antagonist of the postsynaptic dopamine D1-receptors, and selective D2-blocker haloperidol (1 mg/kg) prevented immunostimulating effect of DPDPE. Comparison of effects of the antagonists suggests that delta1-opioidergic immunostimulation has more significant impact due to involvement of dopamine D1-receptors.
