摘要: Orphanin FQ/nociceptin (OFQ/N), the most recently identified endogenous opioid peptide, stimulates prolactin secretion in both male and female rats. OFQ/N, however, did not elicit this stimulatory effect through μ-, δ-, or κ-opiate receptor subtype. The role OFQ/N plays regulation under physiological conditions its mechanism of action are known. purpose these studies was to determine significance pharmacological specificity secretory response OFQ/N. In addition, tuberoinfundibular dopaminergic (TIDA) neurons mediating examined. Opioid receptor-like-1 (ORL-1) receptors were blocked by pretreatment with compound B (Comp B), a purported antagonist, synthesis disrupted ORL-1 antisense oligonucleotides. administration diestrous females measured. Furthermore, suckling-induced ...
