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.

What the researchers found
Mu-opioid receptor function was essential for delta-opioid receptor-mediated anti-hyperalgesia in inflammatory pain, with mu blockade eliminating delta agonist efficacy — demonstrating mu-delta functional dependence and implications for selective opioid drug design.
