TNF and inflammatory bowel disease: The expression of IL-6 (Figure 2C, the middle panel) and TNF-α (Figure 2C, the bottom panel) was higher (IHC score = 2.0 for IL-6 and TNF-α) in the intestinal epithelium of mice with TNBS-induced IBD, but both declined when mice further consumed PAW (IHC score = 1.0 for IL-6 and TNF-α).
