The Bacterial Secretome in IBD

2019-10-28 13:56:54 | BioPortfolio


Secreted bacterial effectors produced by the intestinal microbiota are in part responsible for the proinflammatory effect of the fecal content in inflammatory bowel disease (IBD) patients.


Fecal colonic content will be collected by suction during routine colonoscopy. From the fecal content different fractions (containing soluble bacterial fractions and membrane bound bacterial fractions) will be processed. These bacterial fractions (also termed as bacterial secretome) will be tested for proinflammatory potential in tissue culture assays including epithelial colonic cell lines and dendritic/monocytic cell lines. The main outcome parameter will be the secretion of proinflammatory cytokines from the tissue culture.

For this purpose the investigators will test different groups of patients including patients with active/inactive Crohn's disease or ulcerative colitis, patients with other inflammatory conditions of the colon, patients with colorectal carcinoma and healthy controls undergoing colonoscopy.

Medical and Biotech [MESH] Definitions

Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument along either natural body pathways such as the digestive tract, or through keyhole incisions to examine the interior parts of the body. With advances in imaging, endoscope, and miniaturization of endosurgical equipment, surgery can be performed during endoscopy.
