In Cav1-KO mice, the average score of gastritis (0.7±0.2 WT versus 1.7±0.1 KO; *p = 0.0002, n = 15 per genotype) was more severe (Table 1) than in WT mice, and the stomach mucosa exhibited intramucosal B-cell follicles, foveolar hyperplasia and loss of parietal cells. Here, CAV1 is linked to gastritis.
