STAT6 and colitis: C. rodentium infected mice treated with IL-4 for 3 consecutive days had lower colitis scores than vehicle or Stat6 inhibitor treated mice at 13 dpi (p < 0.05) and by 22 dpi the colitis scores of both vehicle (p < 0.005) and IL-4 (p < 0.05) treated mice had decreased, whereas the scores of Stat6 inhibitor treated mice remained high (Figures 7(a) and 8(a–d)).
