Fimbriae-mediated outer membrane vesicle production and invasion of Porphyromonas gingivalis
Porphyromonas gingivalis is a keystone periopathogen that plays an essential role in the progress of periodontitis. Like other gram-negative bacteria, the ability of P. gingivalis to produce outer membrane vesicles is a strategy used to interact with, and survive within its biological niches. Here we compared the protein components associated with vesicles derived from a fimbriated strain (3327...
متن کاملMajor outer membrane proteins and proteolytic processing of RgpA and Kgp of Porphyromonas gingivalis W50.
Porphyromonas gingivalis is an anaerobic, asaccharolytic Gram-negative rod associated with chronic periodontitis. We have undertaken a proteomic study of the outer membrane of P. gingivalis strain W50 using two-dimensional gel electrophoresis and peptide mass fingerprinting. Proteins were identified by reference to the pre-release genomic sequence of P. gingivalis available from The Institute f...
متن کاملCharacterization of a novel outer membrane hemin-binding protein of Porphyromonas gingivalis.
Porphyromonas gingivalis is a gram-negative, anaerobic coccobacillus that has been implicated as a major etiological agent in the development of chronic periodontitis. In this paper, we report the characterization of a protein, IhtB (iron heme transport; formerly designated Pga30), that is an outer membrane hemin-binding protein potentially involved in iron assimilation by P. gingivalis. IhtB w...
متن کاملImmunoreactive antigens recognized in serum samples from mice intranasally immunized with Porphyromonas gingivalis outer membrane vesicles.
Outer membrane vesicles (OMVs) of the periodontopathic bacterium Porphyromonas gingivalis contain a wide range of virulence factors including lipopolysaccharide (LPS), fimbriae and gingipains. We have recently reported strong immunogenicity of OMVs using an intranasal vaccine mouse model. In the present study, we performed sub-immunoproteome analysis of OMV-immunized mouse serum samples from si...
متن کاملOuter Membrane Vesicles of Porphyromonas gingivalis Elicit a Mucosal Immune Response
We previously reported that mutation of galE in Porphyromonas gingivalis has pleiotropic effects, including a truncated lipopolysaccharide (LPS) O-antigen and deglycosylation of the outer membrane protein OMP85 homolog. In the present study, further analysis of the galE mutant revealed that it produced little or no outer membrane vesicles (OMVs). Using three mouse antisera raised against whole ...
