This study shows that perinatal morphine exposure in rats causes long-term intestinal microbiota changes that may affect immune system development and increase infection risk.

This study shows that perinatal morphine exposure in rats increases fever and sickness behavior after LPS, suggesting impaired immune function and increased infection susceptibility.

This study shows early life pain in rats increases febrile response and alters brain region activity after an immune challenge in adulthood.

This study shows that perigestational opioid exposure in rats alters alcohol and sucrose reward behaviors, with sex-specific effects on consumption and receptor expression.

This study shows that perinatal morphine exposure reduces social play in adolescent female rats, possibly due to altered oxytocin signaling in the nucleus accumbens.
