After 9 days post infection, the expression of Tnfa (p < 0.001), Il6 (p < 0.0001), Il1b (p < 0.001) and Il10 (p < 0.05) was significantly heightened in the distal colon of infected mice, despite no difference on Foxp3, when compared to non-infected animals (Fig. 3E and Fig. S4). This evidence concerns the gene IL10 and infection.
