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.

What the researchers found
Endogenous opioid peptides have extensive non-opioid receptor activities: immune modulation, cell proliferation control (via OGFr), cardiovascular protection, neuroprotection, and antimicrobial effects — mediated through non-classical receptors and direct physicochemical mechanisms.
Why it matters
Relevant for opioid-peptides, immune-function, receptor-signaling, neuroprotection.
How the study worked
