In accordance with the higher colitis severity of this model, the numbers of IFN-γ+ and IFN-γ+ IL-17A+ CD4+ cells, but not IL-17+ or IL-10+ CD4+ T cells, in the large intestinal lamina propria were higher in LysoPS-treated mice than in control mice (Fig. 4 D). This evidence concerns the gene IL17A and colitis.
