The aim of this study was to investigate the antidepressant-like effect of red wine phenolic extracts in mouse model exposed to exogenous corticosterone. The results showed that 3-week corticosterone injections caused depression-like behavior in mice, as indicated by the significant decrease in sucrose consumption and increase immobility time in the forced swimming test (FST). Red wine phenolic extracts treatment significantly reduced serum corticosterone levels. Moreover, it was found that red wine phenolic extract increased the brain-derived neurotrophic factor protein (BNDF) and tropomyosin-related kinase B (TrkB) phosphorylation and cAMP-responsive element binding protein (CREB) phosphorylation levels in the hippocampus and prefrontal cortex. However, K252a, an inhibitor of TrkB, completely abolished those antidepressant-like effects. These results suggested that the red wine phenolic extracts produce an antidepressant-like effect in corticosteronetreated mice, at least in part, which is possibly mediated by modulating hypothalamic-pituitary-adrenal (HPA) axis, BDNF, TrkB and CREB phosphorylation levels in the brain region of mice.
Resumo
O objetivo deste trabalho foi estudar o efeito antidepressivo de extratos fenólicos do vinho tinto em rato-modelo exposto à corticosterona exógena. Os resultados mostraram que injeções de corticosterona de 3 semanas causaram comportamento semelhante à depressão em ratos, como indicado pela diminuição significativa no consumo de sacarose e aumento do tempo de imobilidade em teste de natação forçada (FST). O tratamento com extratos fenólicos de vinho tinto reduziu significativamente os níveis séricos de corticosterona. Além disso, verificou-se que o extrato fenólico do vinho tinto aumentou a proteína do fator neurotrófico derivado do cérebro (BNDF) e fosforilação da quinase B associada à tropomiosina (TrkB) e os níveis de fosforilação da proteína de ligação ao elemento cAMP-responsivo (CREB) no hipocampo e no córtex pré-frontal. No entanto, K252a, um inibidor de TrkB, aboliu completamente os efeitos do tipo antidepressivo. Estes resultados sugerem que os extratos fenólicos do vinho tinto produzem um efeito antidepressivo em ratos tratados com corticosterona, pelo menos em parte, o que é possivelmente mediado pela modulação do eixo hipotálamo-hipófise-adrenal (HPA), BDNF, TrkB e níveis de fosforilação de CREB na região do cérebro dos ratos.
