Objective: To construct the gene modified probiotic Escherichia coli nissle1917 (EcN) which can express human Elafin protein and to explore its protective effect on the acute colitis in mice.Methods: The recombinant plasmid with human Elafin gene was constructed and then transferred to EcN. Western blot results confirmed that the engineered probiotic expressed Elafin successfully in vitro. Benefiting from its good biocompatibility and ideal targeting ability as a biological carrier, Escherichia coli Nissle 1917 (ECN) has been focused on the treatment strategies of inflammatory bowel disease and tumor. The advantage of a bacterial carrier is that it can express exogenous protein while also acting as a natural capsule by releasing With this in mind, we developed the SLIC system in the probiotic strain E. coli Nissle 1917, which has been shown to colonize liver metastases when delivered orally , thus offering an additional translational route of therapeutic delivery for more advanced metastatic disease. Administration of the probiotic Escherichia coli strain Nissle 1917 (EcN) decreases visceral pain associated with irritable bowel syndrome. Mutation of clbA, a gene involved in the biosynthesis of secondary metabolites, including colibactin, was previously shown to abrogate EcN probiotic activity. As a proof-of-concept study, we chose a well-known probiotic bacterium, Escherichia coli Nissle 1917 (EcN), a host bacterium which has been used for treating gastrointestinal disorders and solid Here we used a synthetic biology approach to develop an engineered probiotic Escherichia coli Nissle 1917 strain that colonizes tumours and continuously converts ammonia, a metabolic waste product A non-pathogenic strain of E.coli (E. Coli Nissle 1917) has been one of the most clinically trialled probiotics with regard to Crohn's disease. In a 1997 double-blind study by Malchow 5 E.Coli Nissle 1917 or placebo was taken daily for twelve months by 32 patients with active Crohn's disease. Both groups also received standard steroid Probiotics, such as Escherichia coli Nissle 1917, are microorganisms that confer beneficial physiological or therapeutic activities. For example, some probiotics can alleviate intestinal inflammation and irritable bowel syndrome, strengthen host innate immune functions or protect the intestinal barrier against pathogens 2 , 3 , 4 .
