Fimbriae assisted bacterial surface display of heterologous peptides
The display of peptide segments on the surface of bacteria offers many new and exciting applications in biotechnology and medical research. Fimbria-assisted display of heterologous sequences is a paradigm for chimeric organelle display on bacteria. Fimbriae are particularly attractive candidates for epitope display for several reasons: (1) they are ...

Bacterial Fimbriae Stimulate Proinflammatory Activation in the Endothelium through Distinct TLRs [PDF]
Abstract The major and minor fimbriae proteins produced by the human pathogen Porphyromonas gingivalis are required for invasion of human aortic endothelial cells and for the stimulation of potent inflammatory responses. In this study, we report that native forms of both the major and minor fimbriae proteins bind to and signal through ...

P-fimbriae, bacterial adhesion, and pyelonephritis. [PDF]
L'aptitude des agents pathogenes a adherer aux membranes muqueuses est maintenant reconnue comme un facteur potentiel de virulence; elle est souvent en rapport avec la presence de filaments proteiniques capables de reconnaitre des recepteurs, souvent glucidiques sur les membranes des cellules epitheliales.

Biofilm formation by Klebsiella pneumoniae on indwelling medical devices increases the risk of infection. Both type 1 and type 3 fimbriae are important factors in biofilm formation by K. pneumoniae. We found that a putative enzyme II (EII) complex of the

Type 3 Fimbriae Encoded on Plasmids Are Expressed from a Unique Promoter without Affecting Host Motility, Facilitating an Exceptional Phenotype That Enhances Conjugal Plasmid Transfer. [PDF]
Horizontal gene transfer (HGT), the transmission of genetic material to a recipient that is not the progeny of the donor, is fundamental in bacterial evolution.

Chaperone-tip adhesin complex is vital for synergistic activation of CFA/I fimbriae biogenesis.
Colonization factor CFA/I defines the major adhesive fimbriae of enterotoxigenic Escherichia coli and mediates bacterial attachment to host intestinal epithelial cells.

Adhesion of bacteria to the glycosylated surface of their target cells is typically mediated by fimbrial lectins, exposed on the bacterial surface. Among the best-investigated and most important fimbriae are type 1 fimbriae, for which α-d-mannopyranoside-

Uncoiling mechanics of Escherichia coli type I fimbriae are optimized for catch bonds. [PDF]
We determined whether the molecular structures through which force is applied to receptor-ligand pairs are tuned to optimize cell adhesion under flow. The adhesive tethers of our model system, Escherichia coli, are type I fimbriae, which are anchored to ...

Expression of the short fimbriae ofPorphyromonas gingivalisis regulated in oral bacterial consortia [PDF]
The Mfa1 protein of Porphyromonas gingivalis is the structural subunit of the short fimbriae and mediates coadhesion between P. gingivalis and Streptococcus gordonii. We utilized a promoter-lacZ reporter construct to examine the regulation of mfa1 expression in consortia with common oral plaque bacteria.

Fimbriae are essential virulence factors for many bacterial pathogens. Fimbriae are extracellular structures that attach bacteria to surfaces. Thus, fimbriae mediate a critical step required for any pathogen to establish infection by anchoring a ...
