RESUMEN

ABSTRACTThis study evaluated the effects of Rubus sp. extract on behavioral and neurochemical parameters in female mice submitted to experimental model of depression induced by lipopolysaccharide (LPS). The results indicated that Rubus sp. extract protected against depressive-like behavior induced by LPS. Moreover, the administration of Rubus sp. extract was effective in preventing the increase in reactive species and nitrites levels, as well as the decrease in catalase activity induced by LPS in the cerebral cortex. In the serum, the Rubus sp. extract was effective in preventing the decrease in catalase activity induced by LPS. Treatment with Rubus sp. extract attenuated the increase in acetylcholinesterase activity induced by LPS in the cerebral cortex. Finally, blackberry extract also downregulated IL-1ß levels in cerebral cortex. In conclusion, our findings demonstrated that treatment with Rubus sp. exerted antidepressant, antioxidant, anticholinesterase and anti-inflammatory effects in a model of depressive - like behavior induced by LPS in female mice. This highlights Rubus sp. as a potential therapeutic agent for individuals with major depressive disorder.
