Figure 3. The expressions of IFN-γ and IL-4 on stimulated lymphocytes were evaluated by flow cytometry. A: The frequencies of IFN-γ and IL-4 were detected by flow cytometry. Results of a representative experiment are shown. B: The frequencies of IFN-γ and IL-4 are shown by a histogram. All data shown represent the mean ± SD of at least three independent experiments. *p<0.05 compared with the control group; #p<0.05 compared with the DM-NDR group.
