[The impact of S.gordonii on P. gingivalis on the form of biofilm].

Shanghai kou qiang yi xue = Shanghai journal of stomatology, 2016
To investigate the impact of S.gordonii on the ultrastructure of P. gingivalis biofilm and on the amount of P. gingivalis in biofilm.P. gingivalis and/or S.gordonii grew on the culture slides to form single P. gingivalis biofilm and heterotypic biofilm of P.gingivalis-S.gordonii.

Cytokine profiles of Porphyromonas gingivalis‐reactive T lymphocyte lines and clones derived from P. gingivalis‐infected subjects

Oral Diseases, 1995
Porphyromonos gingivolis is generally recognized as a major periodontopathogen such that a study of T cell responses to this organism may help to elucidate immune regulation in periodontal disease.OBJECTIVE The aim of this study was to examine interleukin (IL)‐4, interferon (IFN)‐gamma and IL‐10 production by p‐gingivolis‐responsive T cell lines and ...

P. gingivalis Regulates the Expression of Cathepsin B and Cystatin C

Journal of Dental Research, 2008
Porphyromonas gingivalis is a major etiological agent of periodontitis that could affect the expression of Cathepsins B and C by disrupting the balance between these enzymes and their inhibitor, Cystatin C. We tested this hypothesis by infecting human oral epithelial cells with P. gingivalis or activating solely by its lipopolysaccharide.

Dendritic-NK Cell Interactions in P. gingivalis -specific Responses

Journal of Dental Research, 2005
Patients with localized aggressive periodontitis have type-1 cytokines in gingival crevicular fluid and high titers of IFN-γ-dependent IgG2 reactive with P. gingivalis in gingival crevicular fluid and serum. Localized aggressive periodontitis monocytes spontaneously differentiate into dendritic cells that can stimulate IFN-γ production by NK cells ...

Mechanism and functional verification of genes by virulence factors of P. gingivalis in ferroptosis

Archives of Oral Biology
Porphyromonas gingivalis (P. gingivalis) is a key etiological agent in periodontitis and functions as a facultative intracellular microorganism and involves many virulence factors. These virulence factors participate in multiple intracellular processes, like ferroptosis, the mechanistic underpinnings remain to be elucidated.

[Identification of P. gingivalis P. intermedia P. nigrescens by 16S rDNA and membrane microarray chip].

Shanghai kou qiang yi xue = Shanghai journal of stomatology, 2015
The aim of this study is to identify three kinds of black-pigmented periodontal pathogens P. gingivalis Pg, P. intermedia Pi, P. nigrescens Pn by 16S rDNA and microarray.A pair of universal primers which can amplify a section of conservative domain of bacterial 16S rDNA based on the sequences of 16S rDNA in Genebank were designed.
