Reduction of IL-17A Might Suppress the Th1 Response and Promote the Th2 Response by Boosting the Function of Treg Cells during Silica-Induced Inflammatory Response In Vitro
Figure 1
Anti-IL-17A mAb and IL-1Ra decreased the secretion of IL-17A in silica-induced Th response in vitro. (a) The secretion of IL-17A in supernatant of the macrophage-lymphocyte cocultured system was assayed by ELISA. ((b) and (c)) The expressions of IL-17A and ROR-t in lymphocytes were assayed by realtime PCR. The concentration of IL-1Ra is 15 μg/mL and the concentration of anti-IL-17A mAb is 20 μg/mL. Data were presented as (). #: , significantly different compared with the PBS group. Δ: , significantly different compared with the silica group.
