Opioid Peptides Have a Secret Life Beyond Pain: Immune, Growth, and Cardiovascular Effects

Opioid peptides exert extensive non-opioid-receptor effects including immune modulation, cell growth regulation, cardiovascular protection, and neuroprotection — activities mediated through non-classical pathways like OGFr and direct membrane interactions.
