Moreover, cytokine profiles of the ilea of WT and Crtam−/− mice after infection with T. gondii confirmed a strong reduction in the abundance of IL-17A and IL-17F mRNAs in Crtam−/− mice, while the amounts of IFN-γ, IL-22, and IL-10 mRNAs were not significantly different between WT and Crtam−/− strains. The gene discussed is IL17F; the disease is infection.
