Aerobic Exercise Alters Opioid Receptors Following Chronic Alcohol Exposure, James N. Brundage
Aerobic Exercise Alters Opioid Receptors Following Chronic Alcohol Exposure, James N. Brundage
Theses and Dissertations
Opioid receptors have been a target of pharmacological manipulation in alcohol use disorder (AUD) recovery protocols for many years. Aerobic exercise, a common adjunct in AUD recovery, is known to modulate opioid receptors (ORs) both during both acute and long term exposure. The three subtypes of ORs: mu (MOR), delta (DOR), and kappa (KOR) are all expressed on neurons in the mesocorticolimbic circuitry. Kappa-opioid receptors are expressed directly on dopamine (DA) neuron terminals in the nucleus accumbens (NAc). Mu and Delta ORs are expressed on cholinergic interneurons (CINs) and GABA neurons in the NAc. In alcohol dependent rodents, KORs are …
