Morphine treatment altered endogenous opioid peptide (POMC/prodynorphin) production in inflammatory immune cells, with implications for how opioid drugs interact with the body's natural inflammatory pain control.

What the researchers found
Morphine modified proopiomelanocortin and prodynorphin system activity in immune cells during zymosan-induced peritonitis, demonstrating that exogenous opioid drugs alter the endogenous opioid-immune pain control system at inflammation sites.
Why it matters
