Effect of sodium selenite and SIN1 on the redox balance of imDCs. The activity of superoxide dismutase (A) and glutathione peroxidase (B) and content of glutathione (C) were assayed by their respective kits and read using a spectrophotometer, and the level of reactive oxygen species was detected by flow cytometry (D). Data are presented as mean±SD of 3 independent experiments. * P<0.05, ** P<0.01, *** P<0.001, compared with the control group. #
P<0.05, ###
P<0.001, compared with the SIN1 group.
