Figure 6. Gastric microflora are irrelevant to gastritis development in AID−/− mice.

Figure 6

AID−/− and AID+/+ mice were raised under germ-free (GF) or conventional (CV) conditions to examine whether the presence of gastric microflora affects the development of gastritis. (A) Histological examination of gastric tissues from AID−/− and AID+/+ mice maintained under GF condition. (B) Stomach weight and pathological score of gastritis were compared between AID−/− mice in GF and CV conditions. (C) Cytokine expression levels in gastric tissues of AID−/− and AID+/+ mice under GF and CV conditions were measured by Q-PCR. The mRNA expression level of each cytokine was normalized to that of GAPDH.
