Characterization of Porphyromonas gingivalis-induced degradation of epithelial cell junctional complexes.
Porphyromonas gingivalis is considered among the etiological agents of human adult periodontitis. Although in vitro studies have shown that P. gingivalis has the ability to invade epithelial cell lines, its effect on the epithelial barrier junctions is not known. Immunofluorescence analysis of human gingival epithelial cells confirmed the presence of tight-junction (occludin), adherens junction...
متن کاملPorphyromonas gingivalis
Editorial Periodontal diseases have long been associated with an increased, yet moderate, risk for the development of atherosclerosis and coronary heart disease. The postulated mechanism underlying this association is the low grade systemic inflammatory response to pathogens engaged in chronic periodontal infection, such as Porphyromonas gingivalis, which may facilitate atheroma formation and t...

Characterization of a hemophore-like protein from Porphyromonas gingivalis.
The porphyrin auxotrophic pathogen Porphyromonas gingivalis obtains the majority of essential iron and porphyrin from host hemoproteins. To achieve this, the organism expresses outer membrane gingipains containing cysteine proteinase domains linked to hemagglutinin domains. Heme mobilized in this way is taken up by P. gingivalis through a variety of potential portals where HmuY/HmuR of the hmu ...
