Delta opioid modulation of hypothalamic serotonergic neurotransmission in the ovariectomized and steroid-primed rat.

: OBJECTIVES: We have investigated the modulating effects of DPDPE (a delta opioid agonist) and opioid receptor antagonists on both LH release and indoleamine concentrations in specific hypothalamic regions of the ovx and steroid-primed rat. METHODS: DPDPE was intracerebroventricularly infused alone or with either ICI 154129 (a delta op.....
