Mu-Opioid Receptors Are Required for Delta-Opioid Pain Relief to Work

Mu-opioid receptor activation was essential for delta-opioid receptor-mediated anti-hyperalgesia, revealing that mu and delta receptors cooperate rather than working independently — delta analgesics need functional mu signaling.
