Mitigation of IL-17 response to ETBF in absence of Tregs is not restricted to CD4+ (Th17) cells.. B6.Foxp3DTR mice were inoculated with ETBF. Either 150 μl purified sterile H2O or 50 ng/g DT was administered ip on days -2, -1, 1, 3, & 5. Colonic LPLs from each mouse were harvested on day 7. Cells were stimulated ex vivo, followed by ICS. Dot plots show viable LPLs from 1 mouse per group and are representative of 2 experiments.
