GSTM1 and infection: Proximal colon mRNA expression is depicted in a heat map (Figure 3A) comparing expression changes occurring with infection (mean fold change of isotype Hb divided by mean fold change of isotype broth) and expression changes when Hb-infected mice were treated with anti-IL-7Rα M595 antibody (mean fold change of anti-IL-7R M595 divided by mean fold change of isotype Hb).
