Bone loss and aggravated autoimmune arthritis in HLA-DRβ1-bearing humanized mice following oral challenge with Porphyromonas gingivalis [PDF]

, 2016
BACKGROUND: The linkage between periodontal disease and rheumatoid arthritis is well established. Commonalities among the two are that both are chronic inflammatory diseases characterized by bone loss, an association with the shared epitope ...

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis

PLOS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P. gingivalis strain ATCC 33277 was recently identified by an in silico structural homology search.

Intracellular Porphyromonas gingivalis Promotes the Tumorigenic Behavior of Pancreatic Carcinoma Cells

Cancers, 2020
Porphyromonas gingivalis is a member of the dysbiotic oral microbiome associated with oral inflammation and periodontal disease. Intriguingly, epidemiological studies link P. gingivalis to an increased risk of pancreatic cancer.

Hemin availability induces coordinated DNA methylation and gene expression changes in Porphyromonas gingivalis

mSystems, 2023
Periodontal disease is a chronic inflammatory disease in which the oral pathogen Porphyromonas gingivalis plays an important role. Porphyromonas gingivalis expresses virulence determinants in response to higher hemin concentrations, but the underlying ...

Polymicrobial oral biofilm models: simplifying the complex [PDF]

, 2019
Over the past century, numerous studies have used oral biofilm models to investigate growth kinetics, biofilm formation, structure and composition, antimicrobial susceptibility and host–pathogen interactions.

Porphyromonas gingivalis ligada a enfermedad periodontal y su relación con la artritis reumatoide: identificación de nuevos mecanismos biomoleculares

Acta Odontológica Colombiana, 2020
Objetivo: revisar la literatura científica existente con respecto a la patogenicidad de Porphyromonas gingivalis, ligada a enfermedad periodontal (EP) (disbiosis oral), y su asociación con la activación de mecanismos fisiopatológicos en la artritis ...

Antibacterial potential from periodontal dressing raw propolis Trigona itama bee based against Porphyromonas gingivalis: experimental research

Jurnal Kedokteran Gigi Universitas Padjadjaran, 2023
Introduction: One of the procedures used in dentistry to address periodontal disease is periodontal surgery, which can lead to open wounds. Periodontal dressing is a dental material that can help with this issue by accelerate the healing of wounds.

Functional Advantages of Porphyromonas gingivalis Vesicles

PLOS ONE, 2015
Porphyromonas gingivalis is a keystone pathogen of periodontitis. Outer membrane vesicles (OMVs) have been considered as both offense and defense components of this bacterium. Previous studies indicated that like their originating cells, P. gingivalis vesicles, are able to invade oral epithelial cells and gingival fibroblasts, in order to promote ...

Concordance of Porphyromonas gingivalis colonization in families [PDF]

Journal of Clinical Microbiology, 1997
Periodontitis is a widespread disease that appears to be due to a specific bacterial infection. Several species of bacteria have been investigated as potential pathogens, and particularly strong evidence links the presence of Porphyromonas gingivalis with indicators of periodontitis. Information concerning the transmission of P.

Age and prevalence of Porphyromonas gingivalis in children [PDF]

Journal of Clinical Microbiology, 1996
The acquisition of Porphyromonas gingivalis was examined in a cross-sectional study of 198 subjects from 0 to 18 years of age using a PCR-based assay. P. gingivalis was detected in the oral cavities of 37% of subjects and at similar frequencies among subjects of all ages. These data indicate that P. gingivalis may be acquired in the first days of life.
