- Titel:
- Enterococcus faecalis metalloprotease compromises epithelial barrier and contributes to intestinal inflammation.
- Abstract:
- BACKGROUND & AIMS: Matrix metalloproteases (MMPs) mediate pathogenesis of chronic intestinal inflammation. We characterized the role of the gelatinase (GelE), a metalloprotease from Enterococcus faecalis, in the development of colitis in mice. METHODS: Germ-free, interleukin-10-deficient (IL-10(-/-)) mice were monoassociated with the colitogenic E faecalis strain OG1RF and isogenic, GelE-mutant strains. Barrier function was determined by measuring E-cadherin expression, transepithelial electrical resistance (TER), and translocation of permeability markers in colonic epithelial cells and colon segments from
