Treg-cell intrinsic deletion of Blimp1 leads to mild intestinal inflammation. (A) Left: scatter plots showing histology score of cecum (CE), colon (CO) and rectum (RE) among control (Ctrl), CD4creCKO and Foxp3creCKO mice. Each symbol represents one mouse (N ≥ 5 mice/group, Bars indicate average ± SEM. *P < 0.05, **P < 0.01, one-way ANOVA. Right: representative pictures (20X magnification) of histological sections of colon of mice in each group. (B) Representative FACS plots (left) and scatter plots (right) showing the frequency of IL17A expression in TCRβ+ CD4+ Foxp3− cells in spleen (SP) and large intestine lamina propria (LI-LP) from Ctrl, CD4creCKO or Foxp3creCKO mice after stimulation. Right scatter plots: Each symbol represents one mouse (N ≥ 4 mice/group). Bars indicate average ± SEM. **P < 0.01, one-way ANOVA. (C) Representative FACS plots (left) and Scatter plots showing the frequency (right, top) or the total numbers (right, bottom) of IL10-producing cells in TCRβ+ CD4+ Foxp3− or TCRβ+ CD4+ Foxp3+ cells in the SP from Ctrl, CD4creCKO or Foxp3creCKO mice. Each symbol represents one mouse (N ≤ 6 mice/group). Bars indicate average ± SEM. *P < 0.05, **P < 0.01, one-way ANOVA.
