The influence of PHDi on Th17 responses in the Citrobacter rodentium model of infectious colitis. Flow cytometric analysis of intracellular cytokine production from LPL re-stimulated in vitro. (a) Representative dot plots of LPL CD3+CD4+ T cells producing IL-17 and IFN-γ or IL-22 from naive (N) uninfected or C. rodentium-infected mice receiving vehicle (Veh) or PHDi (AKB-4924 5mg kg−1) 14 days post infection. (b) % live CD3+CD4+ T cells expressing IFN-γ, IL-17 and IL-22 or (c) IL-17/IFN-γ and IL-17/IL-22 double-expression. (d) Real-time PCR analysis of il17a and il22 expression in isolated LPL populations. (e) Changes in mucosal thickening (f) spleen weight and (g) histological colitis score in C. rodentium-infected animals with vehicle or PHDi treatment, compared with naive animals. (h) Representative H&E-stained histological images of colons from uninfected naive animals, or C. rodentium infected animals treated with vehicle or PHDi. Data expressed as mean ±s.e.m., (n=6 per group). **P<0.01; ***P<0.005. One-way ANOVA, *P<0.05. ANOVA, analysis of variance.
