Early Life Environment Determines How Alcohol Affects Adult Brain Opioid Peptides
The opioid peptide response to alcohol in adult rats depended on their early life environment (maternal separation history), demonstrating gene-environment interaction for addiction vulnerability through the opioid system.
Quick Facts
What This Study Found
Ethanol-induced changes in brain opioid peptides (dynorphin, enkephalin) in adult Wistar rats were modulated by early postnatal environment (maternal separation), demonstrating gene × early environment interaction programming adult opioid system alcohol sensitivity.
