Frequency of changes in systemic helper T (Th) cells in SMILE Tg mice. (A) Representative immunofluorescence images show the spleen tissues of C57BL/6 and SMILE Tg stained with anti-CD4 antibody (green) and anti-IL-17 antibody (red). Nuclei were stained by DAPI (blue). (B) The splenocytes of C57BL/6 and SMILE Tg were analyzed by flow cytometry. Th1 (CD4+ IFNγ+), Th2 (CD4+ IL-4+), Th17 (CD4+ IL-17+) and regulatory T cell (Treg; CD4+ CD25high Foxp3+) populations are shown. The data are presented as the mean ± standard deviation. *p < 0.05 and ***p < 0.001
