Abstract: Probiotic Escherichia coli Nissle 1917 (EcN) is a good colonizer of the human gut and its efficacy in the inflammatory process undergone in ulcerative colitis has been demonstrated. The probiotic action is mainly through the modulation of intestinal epithelial tight junctions and immune system. Here we review the role of outer membrane vesicles (OMVs) released by this probiotic strain on the modulation of intestinal homeostasis. EcN OMVs enter into host epithelial cells via clathrin-mediated endocytosis and are sorted to lysosomes via endocytic compartments. In cellular models of intestinal barrier, EcN OMVs stimulate the underlying immune system through the intestinal epithelium, triggering immune and defense responses. Thus, the use of probiotic derived OMVs could be a safe probiotic-derived strategy targeting intestinal inflammatory processes.
