(a–c) Relative mRNA abundance of Th1 cytokines ((a) TNF-α; (b) IL-1β; (c) IFN-γ): gastric corpus, 12-week-old mice infected with H. felis *P<0.05, **P<0.01. (d) Western blot demonstrating expression of NF-κB2 in gastric corpus of WT, Nfkb1−/−, Nfkb2−/− and c-Rel−/− mice infected with H. felis for 6 weeks. (e) DNA-binding enzyme-linked immunosorbent assay (ELISA) demonstrating relative DNA binding of NF-κB2 p52 in gastric mucosa of WT, Nfkb1−/−, Nfkb2−/− and c-Rel−/− mice infected with H. felis for 6 weeks, *P<0.05.
