Description

Celiac disease (CD) is a food enteropathy that occurs in genetically susceptible individuals following the ingestion of gluten. Both gluten cytotoxicity and immunity activation play a role in CD pathogenesis; however, the chronological assessment of the different pathogenic mechanisms remains elusive. The models developed so far have only partially addressed this issue. Herein, Ab°DQ8 transgenic mice were administered wheat gliadin and indomethacin for 10 days to induce enteropathy. Gliadin-induced alteration of the small intestinal architecture was associated with increased expression of tissue transglutaminase in the lamina propria and a marked hypoxic environment. Enteropathic mice showed activation of innate immunity, featuring an increase of pro-inflammatory IFN-γ and IL-15 mRNAs, as well as CD11c
