Outline of Final Research Achievements |
We studied effect of long-term exposure to asbestos with MT-2 cells as a regulatory T cell model. It was revealed that long-term exposure to asbestos reduced transcription factors, FoxO1 and FoxP3, in MT-2 cells. Furthermore, FoxO1 target molecules were suppressed by long-term exposure to asbestos. Expression of recombinant FoxP3 enhanced sensitivity to asbestos. These results suggest that exposure to asbestos modifies regulatory T cell function through the inactivation of FoxO1 and FoxP3. These are important to elucidate effect of asbestos on regulatory T cells and tumor immunity.
