We demonstrated previously that the incorporation of a membrane-anchored form of flagellin into influenza virus-like particles (VLPs) improved the immunogenicity of VLPs significantly, inducing partially protective heterosubtypic immunity by intramuscular immunization. Because the efficacy of mucosal vaccination is highly dependent on an adjuvant, and is particularly effective for preventing mu...

objective: pseudomonas aeruginosa is the major cause of septicemia and wound infection in burned patients. immunotraphy is the best practical way for prevention and treatment of these infections. flagella as one of the most important bacterial virulence factors has important role in attachment, motility, chemotaxis and tlr-5-dependent immune response so that it propounded as a vaccine candidate...

Murine monoclonal antibodies to Campylobacter jejuni recognized a flagellin epitope common to most Campylobacter species and an epitope restricted to C. jejuni and C. coli. These epitopes are distinct from the serotype-specific epitope recently detected on the flagellin and have not been described previously.

We have determined the nucleotide sequence of a flagellin gene locus from the haloalkaliphilic archaeon Natrialba magadii, identified the gene products among proteins forming flagella, and demonstrated cotranscription of the genes. Based on the sequence analysis we suggest that different regions of the genes might have distinct evolutionary histories including possible genetic exchange with bac...

The antigenic properties of Bacillus subtilis flagella and periodate-treated flagellin were compared by using immobilization-inhibition and diethylaminoethyl cellulose binding assay. The results suggest that there are both unique and cross-reactive antibodies elicited by B. subtilis flagella and flagellin.

Objective. We hypothesized that HMGB1 in complex with bacterial components, such as flagellin, CpG-ODN, and LPS, promotes HIV-1 replication. Furthermore, we studied the levels of antiflagellin antibodies during HIV-1-infection. Methods. Chronically HIV-1-infected U1 cells were stimulated with necrotic extract/recombinant HMGB1 in complex with TLR ligands or alone. HIV-1 replication was estimate...

Flagella were isolated from strains of Campylobacter jejuni belonging to different heat-labile serogroups and from a strain of Campylobacter fetus, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the flagellin molecular weights (Mr) were approximately 62,000. The flagellins were cleaved by hydrolysis with cyanogen bromide, and sodium dodecyl sulfate-urea peptide gel el...

Bacterial H antigens are specified by flagellin molecules, which constitute the flagellar filament. Escherichia coli 781-55 and E2987-73 are the type strains for H44 and H55 antigens, respectively. Unlike E. coli K-12, they possess two flagellin genes, fliC and fllA, on their chromosomes. However, they are monophasic, expressing exclusively the fllA genes, which specify the type antigens. In th...

A gene encoding a flagellin protein of Campylobacter coli VC167 has been cloned and sequenced. The gene was identified in a pBR322 library by hybridization to a synthetic oligonucleotide probe corresponding to amino acids 4 to 9 of the N-terminal sequence obtained by direct chemical analysis (S. M. Logan, L. A. Harris, and T. J. Trust, J. Bacteriol. 169:5072-5077, 1987). The DNA was sequenced a...

Our previous studies indicated that recombinant rabies viruses (rRABV) expressing chemokines or cytokines (including GM-CSF) could enhance the immunogenicity by recruiting and/or activating dendritic cells (DC). In this study, bacterial flagellin was cloned into the RABV genome and recombinant virus LBNSE-Flagellin was rescued. To compare the immunogenicity of LBNSE-Flagellin with recombinant v...
