英文摘要Parkinson's disease is characterized by slow and progressive degeneration of dopaminergic neurons. Increasing evidence has suggested an important role for exposure to pesticides such as rotenone in the pathogenesis of Parkinson's disease. Although rotenone can elicit immune responses in microglia, the intracellular signaling events mediating these effects are poorly defined. Here we show that cell-free supernatants of rotenone-treated monocytic THP-1 cells induced cytotoxicity in dopaminergic neuroblastoma SH-SY5Y cells. Exposure of THP-1 cells to rotenone led to transient production of reactive oxygen species (ROS) and phosphorylation of Akt. Akt activation was also induced by exogenous hydrogen peroxide. Pretreatment of THP-1 cells with either a phosphatidylinositol 3-kinase (PI3K) inhibitor or ROS scavengers prevented Akt activation and protected SH-SY5Y cells from the cytotoxic effect of conditioned media from rotenone-treated THP-1 cells. Roterione treatment of THP-1 cells also led to upregulation of cyclooxygenase-2 and secretion of prostaglandin E-2. These results suggest that rotenone-induced activation of ROS/PI3K/Akt pathway in THP-1 cells leads to the release of factors that are toxic to SH-SY5Y cells and have implications for the onset of Parkinson's disease.
