Treatment of mice suffering from DSS or TNBS colitis with gallic acid, also found in tormentil (Supplementary Figure S1, Supplementary Table S1), resulted in reduced colonic TNF-α and IFN-γ concentrations [89,90] (Table 3), which further supports our results of basal IFN-γ concentration in MLN taken from tormentil-treated C. jejuni-infected mice (Table 2). Here, IFNG is linked to colitis.
