Chemically defined diet alters the protective properties of fructo-oligosaccharides and isomalto-oligosaccharides in HLA-B27 transgenic ratsDownload
Non-digestible oligosaccharides (NDO) were shown to reduce inflammation in experimental colitis, but it remains unclear whether microbiota changes mediate their colitis-modulating effects. This study assessed intestinal microbiota and intestinal inflammation after feeding chemically defined...
Inulin and fructo-oligosaccharides have divergent effects on colitis and commensal microbiota in HLA-B27 transgenic ratsDownload
Modulation of intestinal microbiota by non-digestible carbohydrates may reduce inflammation in inflammatory bowel disease (IBD). The aim of the present study was to assess the effects of inulin and fructo-oligosaccharides (FOS) on intestinal microbiota and colitis in HLA-B27 transgenic rats, a...
Lactobacillus reuteri maintains a functional mucosal barrier during DSS treatment despite mucus layer dysfunctionDownload
Treatment with the probiotic bacterium Lactobacillus reuteri has been shown to prevent dextran sodium sulfate (DSS)-induced colitis in rats. This is partly due to reduced P-selectin-dependent leukocyte- and platelet-endothelial cell interactions, however, the mechanism behind this protective...
There is an increase in the prevalence of inflammatory bowel disease (IBD) worldwide, and this appears to be associated with an increase in the consumption of a Western diet high in fat and sugar, and low in fiber. Previous work shows that two-day exposure to high sugar diets increases the...
The tumor suppressor protein Ras association domain family 1A (RASSF1A) has roles in multiple signaling pathways including modulating apoptosis, the cell cycle, DNA damage, and microtubule organization. RASSF1A has been shown to be one of the most frequently epigenetically silenced genes in a...
The intestinal microbiota plays a role in Salmonella-induced colitis independent of pathogen colonizationDownload
The intestinal microbiota is composed of hundreds of species of bacteria, fungi and protozoa and is critical for numerous biological processes, such as nutrient acquisition, vitamin production, and colonization resistance against bacterial pathogens. We studied the role of the intestinal...
The role of small intestinal permeability in the pathogenesis of colitis in the interleukin-10 gene deficient mouseDownload
It is currently believed that the etiology of inflammatory bowel disease involves an aberrant immune response towards the gastrointestinal microbial flora. In addition, an increase in intestinal paracellular permeability may also be a contributing factor of disease, as it precedes disease in...
