Relationships between cellular events and signaling pathways in various pesticide-affected neural cells

Various pesticides are considered hazardous to human health. Of particular concern are potential problems of neurotoxicity associated with their use. Cellular toxicity may manifest as a variety of biological events, such as carcinogenesis (mutagenesis) and/or cell death. Recent reports indicate that signaling pathways regulate these cellular events. Thus, the toxicity of pesticides in cells may involve modulation of signaling pathways. In this review, we mainly focus on relationships between cellular events and signaling pathways in various pesticide-affected neural cells. Our data and those of related studies suggest that these pesticides affect both the viability and various signaling pathways of neural cells.
