| Research Abstract |
The expression of CXCR3 in peripheral CD4+ T cells was decreased in asbestos-related patients with pleural plaque and malignant mesothelioma, and IFN-γexpression was impaired in only patients with malignant mesothelioma. Additionally, in vitro study showed that IL-17 expression was enhanced while CXCR3 and IFN-γexpression were suppressed by chronic exposure of CD4+ T cells to asbestos. These results suggested that chronic exposure to asbestos might induce impairment of antitumor immune function and promotion of tumor proliferation.
