Baicalin reverse AMPA receptor expression and neuron apoptosis in chronic unpredictable mild stress rats.


PMID 25065744

Abstract

Changes of a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor expression could impacts the viability of neurons and brain levels of brain-derived neurotrophic factor (BDNF) expression in the key brain structures in the pathophysiology of depressive disorder. In the present study, chronic unpredictable mild stress (CUMS) degraded performance decreased AMPA receptor expression and increased neuron apoptosis. Treatment with baicalin (20, 40mg/kg) significantly reversed these changes. This study demonstrates that baicalin has potent antidepressant effect, likely through up-regulated the expression of AMPA receptor and suppression neuron apoptosis in CUMS-treated rats.
