Mechanism Underlying Acupuncture-Ameliorated Depressive Behaviors by Enhancing Glial Glutamate Transporter in Chronic Unpredictable Mild Stress (CUMS) Rats

摘要

BackgroundMajor depressive disorder (MDD) is a recurrent mental illness worldwide. The glutamatergic neurotransmission system is now a target for antidepressant therapy because it takes part in synaptic plasticity and cognition in physical condition and has a potential excitatory neurotoxicity in pathological conditions. Glial glutamate transporter EAAT2 performs 90% of Glu neurotransmission. Therefore, the aim of the study was to evaluate the effect of acupuncture on depressive behaviors and EAAT2 in CUMS.
