Ontogeny and molecular weight of immunoreactive arginine vasopressin and corticotropin-releasing factor in the ovine fetal hypothalamus.

abstract：:Cellular actions of nociceptin/orphanin FQ (N/OFQ) resemble those of micro-, delta-, and kappa-opioids, i.e. activation of inwardly rectifying K(+) conductance, inhibition of high-voltage-activated Ca(2+) channel currents, and impediment of neurotransmitter release. Differences in ORL(1) and micro-receptor distributio...
