Nociceptin Blocks ALL Three Types of Opioid Pain Relief in the Spinal Cord

Nociceptin/orphanin FQ blocked antinociception induced by mu, kappa, AND delta opioid agonists at the spinal level, confirming it as a universal anti-opioid peptide that counteracts all forms of opioid-mediated pain relief.

What This Study Found

Nociceptin/OFQ blocked spinal antinociception from mu (DAMGO), kappa (U50,488H), and delta (DPDPE) opioid agonists in the cold water tail-flick test, confirming nociceptin as a universal anti-opioid peptide opposing all three opioid receptor systems.
