Improved adhesive properties of recombinant bifidobacteria expressing the Bifidobacterium bifidum-specific lipoprotein BopA
BACKGROUND Bifidobacteria belong to one of the predominant bacterial groups in the intestinal microbiota of infants and adults. Several beneficial effects on the health status of their human hosts have been demonstrated making bifidobacteria interesting candidates for probiotic applications. Adhesion of probiotics to the intestinal epithelium is discussed as a prerequisite for colonisation of a...

28 The ability of bifidobacteria to adhere to the intestine of human host is considered to be 29 important for efficient colonization and achieving probiotic effects. Bifidobacterium 30 bifidum strains DSM20456 and MIMBb75 adhere well to human intestinal cell lines, 31 Caco-2 and HT-29. Surface lipoprotein BopA has previously been described to be 32 involved in mediating adherence of B. bifidum...
متن کاملImplication of an outer surface lipoprotein in adhesion of Bifidobacterium bifidum to Caco-2 cells.
We found that the human intestinal isolate Bifidobacterium bifidum MIMBb75 strongly adhered to Caco-2 cells. Proteinase K and lithium chloride treatments showed that proteins play a key role in MIMBb75 adhesion to Caco-2 cells. By studying the cell wall-associated proteins, we identified a surface protein, which we labeled BopA. We purified the protein chromatographically and found that it func...
متن کاملThe adhesive properties of coacervated recombinant hybrid mussel adhesive proteins.
Marine mussels attach to substrates using adhesive proteins. It has been suggested that complex coacervation (liquid-liquid phase separation via concentration) might be involved in the highly condensed and non-water dispersed adhesion process of mussel adhesive proteins (MAPs). However, as purified natural MAPs are difficult to obtain, it has not been possible to experimentally validate the coa...
متن کاملStrengthening of the intestinal epithelial tight junction by Bifidobacterium bifidum
Epithelial barrier dysfunction has been implicated as one of the major contributors to the pathogenesis of inflammatory bowel disease. The increase in intestinal permeability allows the translocation of luminal antigens across the intestinal epithelium, leading to the exacerbation of colitis. Thus, therapies targeted at specifically restoring tight junction barrier function are thought to have ...
