The effect of endurance exercise and methadone on μ-opioid receptor gene expression in morphine-dependent rats following withdrawal syndrome

Opiate dependence (e.g., morphine) is one of the most important problems affecting human health. Morphine reduces the irritability of neurons in the pain pathway by attaching to some such opioid receptors such as μ receptor (MOR). Exercise can improve destructions due to opiate dependence in many of the body organs including nerve systems. Thus, the aim of this study was to investigate the effect of endurance exercise training (8 weeks of...
