Early Life Environment Permanently Shapes Brain Opioid Peptides Through Adulthood
Postnatal environment (maternal care quality) permanently altered brain opioid peptide (dynorphin, enkephalin) levels in young and adult rats, with effects persisting through maturation — early life programs the opioid system.
Quick Facts
What This Study Found
Postnatal environment quality produced lasting changes in brain opioid peptide levels (dynorphin, enkephalin) across development into adulthood in Wistar rats, demonstrating enduring early-life programming of the opioid system that may predispose to later psychopathology.
