Neutrophil elastase alters the murine gut mirobiota resulting in enhanced Salmonella colonization
Download2012
Hartmann, Martin, Sekirov, Inna, Finlay, B. Brett, Al-Zahrani, Fatimah, Willing, Benjamin P., Ferreira, Rosana B. R., Gill, Navkiran, Antunes, L. Caetano M.
The intestinal microbiota has been found to play a central role in the colonization of Salmonella enterica serovar Typhimurium in the gastrointestinal tract. In this study, we present a novel process through which Salmonella benefit from inflammatory induced changes in the microbiota in order to...

Small intestine early innate immunity response during intestinal colonization by Escherichia coli depends on its extra-intestinal virulence status

Denamur, Erick, Tourret, Jérôme, Dion, Sara, Willing, Benjamin P., Wachtel, Sarah, Finlay, B. Brett, Dufour, Nicolas, Croxen, Matthew A.
Uropathogenic Escherichia coli (UPEC) strains live as commensals in the digestive tract of the host, but they can also initiate urinary tract infections. The aim of this work was to determine how a host detects the presence of a new UPEC strain in the digestive tract. Mice were orally challenged...

The intestinal microbiota plays a role in Salmonella-induced colitis independent of pathogen colonization

Antunes, L. Caetano M., Gill, Navkiran, Russell, Shannon L., Finlay, B. Brett, Ferreira, Rosana B., Croxen, Matthew A., Willing, Benjamin P.
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...

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 role of intestinal microbiota in development of irinotecan toxicity and in toxicity reduction through dietary fibres in rats

Baracos, Vickie, Dieleman, Levinus, Farhangfar, Arazm, Lin, Xiaoxi B., Gänzle, Michael G., Sawyer, Michael B., Valcheva, Rosica, Schieber, Andreas
CPT-11 is a drug used as chemotherapy for colorectal cancer. CPT-11 causes toxic side-effects in patients. CPT-11 toxicity has been attributed to the activity of intestinal microbiota, however, intestinal microbiota may also have protective effects in CP!-11 chemotherapy. This study aimed to...

The role of small intestinal permeability in the pathogenesis of colitis in the interleukin-10 gene deficient mouse
DownloadSpring 2011
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...

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...
