AB  - Antidepressant fluoxetine (Flx) is the first therapeutic choice for the treatment of major depression (MD), however neuroanatomical spots of its action remain unclear. Immunohistochemical detection of c-Fos protein expression has been used for mapping activated neuronal circuits upon various stressors and drugs. We investigated the effect of 3 weeks of Flx treatment (15 mg/kg/day) on changes in neuronal activity, by mapping the number of c-Fos+ cells, in several brain subregions in adult male rats of control and following 3 weeks of chronic social isolation (CSIS), an animal model of depression. The aim was to identify brain subregions activated by vehicle or Flx treatment in both controls or simultaneously applied with CSIS. Flx prevented depressive- and anxiety-like behaviors in CSIS rats. In controls, Flx increased the number of c-Fos+ cells in the anterior/posterior piriform cortex (aPirCx, pPirCx), retrosplenial cortex dysgranular (RSD) and granular, c region (RSGc), dorsal hippocampal subregions (CA1d, CA2, CA3d, DGd), lateral habenula (LHB), paraventricular thalamic nucleus, posterior part (PVP) and lateral/basolateral complex of amygdala (LA/BL). CSIS-induced neuronal activation was observed in brain subregions implicated in mood and other mental disorders such as aPirCx, pPirCx, caudate putamen (CPu), acumbens nucleus shell (AcbSh), RSD, RSGc, DGd, PVP and LA/BL. Flx increased neuronal activation in both controls and CSIS rats in the CA1d, CA2, CA3d, PVP, LA/BL, while in striatum increased neuronal activation was observed only in CSIS. Our data identify activated CSIS-related brain subregions and/or Flx treatment, in which Flx increased c-Fos protein expression in CSIS rats.

AB  - Olanzapine (Olz) is an atypical antipsychotic used to treat depression, anxiety and schizophrenia, which can be caused by chronic psychosocial stress. c-Fos protein expression has been used as an indirect marker of neuronal activity in response to various forms of stress or pharmacological treatments. We examined the effects of a 3-week treatment of Olz (7.5 mg/kg/day) on c-Fos protein expression in stress-relevant brain sub/regions, its relationship with isolation-induced behavioral changes, and potential sites of Olz action on control and male rats exposed to 6 weeks of chronic social isolation (CSIS), an animal model of depression. Olz treatment reversed depression- and anxiety-like behaviors induced by CSIS and suppressed a CSIS-induced increase in the number of c-Fos-positive cells in subregions of the dorsal hippocampus, ventral (v) DG, retrosplenial cortex, and medial prefrontal cortex. In contrast, no change in c-Fos expression was seen in the CA3v, amygdala and thalamic, hypothalamic or striatal subregions in Olz-treated CSIS rats, suggesting different brain sub/regions’ susceptibility to Olz. An increased number of c-Fos-positive cells in the CA1v, amygdala and thalamic, hypothalamic and striatal subregions in controls as well as in the CA1v and subregion of the hypothalamus and nucleus accumbens in Olz-treated CSIS rats was found. Results suggest the activation of brain sub/regions following CSIS that may be involved in depressive and anxiety-like behaviors. Olz treatment showed region-specific effects on neuronal activation. Our data contribute to a better understanding of the mechanisms underlying the CSIS response and potential brain targets of Olz in socially isolated rats. © 2018 IBRO
