Expression of GABA and glutamate vesicular transporter in depressed mice / 重庆医学

ABSTRACT

Objective To study the expression of vesicular GABA transporter and vesicular glutamate transporter 1 in de‐pression .Methods Mice was divided into control group and defeat group stochastically .By social defeat model and social avoidance , the defeat group was divided into two groups:susceptible group and unsusceptible group .Synaptic proteins were extracted respec‐tively from the 3 groups .We detected the expression abundance of VGAT and VGLUT1 by Western blot .Results Compared with the control group ,in susceptible group ,the residence time in the contact area was significantly reduced ,and the residence time in the corner area was significantly increased ,with statistical difference(P0 .05) .In the striatum ,although the expression levels of VGAT and VGLUT1 were increased in susceptible group ,but in unsusceptible group ,the expression of these proteins also increased significantly .Conclusion The prefrontal cortex and hippo‐campus excitability and inhibitory vesicle transport were changed in depression ,which may relate to the transcription disorder .
