The aim of the present study is to assess the neurogenesis effect of venlafaxine in the frontal cortices and nucleus accumbens of mice exposed to chronic mild stress (CMS) for 3 weeks. Mice were divided into three groups: Group (1) was control, non stressed, saline- treated mice, group (2) was control exposed to chronic mild stress, saline- treated mice and group (3) was treated by venlafaxine in dose of 8 mg/kg/day during exposure to chronic mild stress for another 3 weeks. The following parameters were measured at the end of the 6th week of the study: sucrose consumption & serum corticosterone in mice as indicators for induction of stress, brain derived neurotropic factor [BDNF] level in the frontal cortex and nucleus accumbens of mice as a marker of neurogenesis. The results showed that administration of venlafaxine ip to mice exposed to CMS produced significant (p<0.05) decrease of the serum corticosterone level in mice compared to stressed & saline-treated group (2). Additionally, significant (p<0.05) increase in BDNF concentration in both frontal cortices and nucleus accumbens of stressed mice compared with both control and stressed non-treated groups (1&2). The results of the present work provide an evidence for potential neurogenesis effect of venlafaxine which might add benefits to its therapeutic use in treatment of depressed mood.
