Background and Objective: Pseudomonas aeruginosa is an opportunistic pathogen that causes severe and lethal infections in immunocompromised individuals. This bacterium possesses a single polar flagellum. Flagellum and its subunit Flagellin play important roles in the pathogenesis of P. aeruginosa. Flagellin induces immune responses by interaction of its N-terminal domain with TLR-5. Our main ai...
pseudomonas aeruginosa as an opportunistic pathogen is a significant cause of acute and chronic infections in patients with compromised defenses. this bacterium is motile via a single polar flagellum made of polymerized flagellin subunits differentiated into two major serotypes: a and b. flagellin plays an important role as a virulence factor in the adhesion, colonization and invasion of p. aer...

results cloning and subcloning of the flic gene were confirmed by colony pcr, restriction enzymes digestion and dna sequencing of the recombinant plasmids pprime-flic and pvax-flic. the expression of flagellin protein in eukaryotic cells was approved by immunofluorescence assay (ifa), western blotting analysis and the reverse transcriptase polymerase chain reaction (rt-pcr) method. conclusions t...
Abstract Background In inflammatory bowel disease (IBD), including Crohn’s (CD) and ulcerative colitis (UC), CD4+ T cell-responses to unknown microbial antigens drive intestinal inflammation. Both hypo- or hyperactive anti-microbial innate immunity may underlie these pathogenic T-cell responses. Previously, IgG responses Lachnospiraceae flagellins were detected in spontaneously colitic mice wit...
Pseudomonas aeruginosa possesses a polar flagellum made up of flagellin subunits that encoded by fliC gene. Flagellin from several strains of P. aeruginosa on the basis of reaction with polyclonal antibodies and apparent molecular weight was divided into a or b types. Material and Methods: After extraction of the genomic DNA from two standard strains 8821M (Type a) and PAO1 (Type b) and some c...
Monoclonal antibodies directed against the major Borrelia burgdorferi flagellar protein, the 41-kilodalton (kDa) protein flagellin, were used to monitor cloning and expression of the flagellin gene from a Borrelia burgdorferi genomic library. The structure of the gene was analyzed, and recombinant nonfusion flagellin was produced in Escherichia coli. A DNA sequence analysis of the 41-kDa flagel...
Bacillus sp. PS3 produces a glycosylated flagellin. In this study, a number of the glycosylated residues of the flagellin protein were found to be located in the central variable region of this protein. We also report that the motility defect of the Bacillus subtilis flagellin mutant was complemented by Bacillus sp. PS3 flagellin variants without glycosylation, which contained amino acid substi...
The aim of this study was to separate, purify, and identify Salmonella paratyphi A flagellin, and to prepare its antisera. Primary flagellin was isolated from S. paratyphi A using the acid lysis method. The flagellin was purified with weak anion exchange chromatography and the protein was identified with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), Western blot, and neg...
A number of studies have clearly demonstrated that flagellin is a potent adjuvant that promotes robust immune responses when it is given with a protein antigen. In view of the potential biological and practical benefits of a recombinant protein vaccine composed of a single fusion protein containing flagellin and antigen, we have evaluated the efficacy of a fusion protein composed of flagellin a...
