英文摘要
We previously reported that MT-2 cells, model of regulatory T cells, showed resistance to high concentration of asbestos and up-regulation of IL-10 and TGFβ production after long-term exposure to low concentration of asbestos. In this study, we analyzed the involvement of transcription factors, FoxP3, NFAT and FoxO1, in change of functions of MT-2 cells induced by asbestos. It was revealed that long-term exposure to asbestos reduced expression of FoxP3 and FoxO1, and FoxO1 regulated apoptosis induced by asbestos. These results are important for elucidating the mechanism of up-regulation of regulatory T cell induced by asbestos.
