Postbiotics are functional bioactive substances manufactured during fermentation in a food matrix, which can be used to improve human health, but their influence on the adhesion potential and physicochemical cell surface of probiotics is still unclear. We examined postbiotic produced by Escherichia coli Nissle 1917 labneh properties (auto-aggregation, hydrophobicity, co-aggregation) capacities ...

Considerable evidence suggests that insulin resistance is closely linked to Parkinson's disease (PD), leading agents aiming at treating diabetes can be regarded as new neuroprotective strategies in PD, notably glucagon-like peptide-1 (GLP-1). However, the extremely short half-life of GLP-1 due degradation by ubiquitous proteolytic enzyme limits its clinical application. In this study, we engine...

The role of intestinal microbiota and probiotics in prevention and treatment of infectious diseases, including diarrheal diseases in children and animal models, is increasingly recognized. Intestinal commensals play a major role in development of the immune system in neonates and in shaping host immune responses to pathogens. Lactobacilli spp. and Escherichia coli Nissle 1917 are two probiotics...

The probiotic bacterium Escherichia coli Nissle 1917 (EcN) constitutes a prospective vector for delivering heterologous therapeutic molecules to treat several human disorders. To add versatility to this carrier system, bacteria should be equipped with expression modules that can be regulated deliberately in a temporal and quantitative manner. This approach is called in vivo remote control (IVRC...

Escherichia coli Nissle 1917 (EcN) is a probiotic strain with proven efficacy in inducing and maintaining remission of ulcerative colitis. However, the microbial factors that mediate these beneficial effects are not fully known. Gram-negative bacteria release outer membrane vesicles (OMVs) as a direct pathway for delivering selected bacterial proteins and active compounds to the host. In fact, ...

We evaluated the effects of the probiotic Escherichia coli Nissle 1917 (EcN) and the antibiotic Ciprofloxacin (Cipro) on mRNA expression of intestinal epithelial cells (IEC) in gnotobiotic (Gn) piglets colonized with a defined commensal microflora (DMF) and inoculated with human rotavirus (HRV) that infects IECs. We analyzed mRNA levels of IEC genes for enteroendocrine cells [chromogranin A (Cg...
