Objective To investigate the effect of running exercise on depression-like behaviors in chronic unpredictable stress (CUS)-induced depression mice and GABAergic interneurons, PV+ interneurons and ratio of GAD67+/PV+ cells in medial prefrontal cortex (mPFC). Methods After mouse model of depression was successfully established through CUS, these male C57BL/6 mice aged 4~6 weeks were randomly divided into control group, CUS control group and CUS+running group according to the results of sucrose preference test. The behaviors of the 3 groups were evaluated with sucrose preference test, forced swimming test and tail suspension test. The mRNA expression levels of GAD1, GAD2, PV and CCK in mPFC of mice were detected using qRT-PCR. The number of GABAergic interneurons and PV+ interneurons in mPFC of mice were quantified using immunohistochemical assay and unbiased stereological technique, and the ratio of PV+/GAD67+ cells was calculated. Results Compared with those in CUS control group, the mice from the CUS+running and control groups showed a significantly higher percentage of sucrose preference (P0.05). The mRNA level of PV, number of PV+ interneurons and ratio of PV+/GAD67+ cells in mPFC were remarkably lower in the CUS group than the CUS +running group and control group (P |
