LptO (PG0027) is required for lipid A 1-phosphatase activity in Porphyromonas gingivalis W50 [PDF]

, 2017
Porphyromonas gingivalis produces outer membrane vesicles (OMVs) rich in virulence factors, including cysteine proteases and A-LPS, one of the two lipopolysaccharides (LPSs) produced by this organism. Previous studies had suggested that A-LPS

Immune Evasion Strategies of Porphyromonas gingivalis [PDF]

Journal of Oral Biosciences, 2011
Porphyromonas gingivalis is strongly correlated with chronic periodontitis. Its chronic persistence in the periodontium depends on its ability to evade host immunity without inhibiting the overall inflammatory response, which is actually beneficial for this and other periodontal bacteria.

Stress response of Porphyromonas gingivalis [PDF]

Oral Microbiology and Immunology, 1994
The heat shock response of Porphyromonas gingivalis was examined by 1 ‐ and 2‐dimensional polyacrylamide gel electrophoresis after metabolic labeling with [14C]‐amino acids. When P. gingivalis cells were shifted from 37° C to 42° C, elevated synthesis of 4 proteins with the apparent molecular weight of 92, 80, 74, and 62 kDa was observed, and synthesis

Biointerface Membranes Orchestrating Site‐Specific Osteoimmunomodulatory and Antibacterial Effects for Enhanced Osseous Regeneration in Periodontal Therapy

Advanced Functional Materials, EarlyView.
Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

Polymicrobial periodontal disease triggers a wide radius of effect and unique virome. [PDF]

, 2020
Periodontal disease is a microbially-mediated inflammatory disease of tooth-supporting tissues that leads to bone and tissue loss around teeth. Although bacterially-mediated mechanisms of alveolar bone destruction have been widely studied, the effects of

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 ...

Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

Advanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Porphyromonas gingivalis in Dental Caries: Prevalence and Association with Diabetes and Smoking

Journal of Medical Sciences and Health
Background and objectives: Porphyromonas gingivalis is an intraoral anaerobic bacterium that causes periodontal disease. Diabetes and smoking are thought to be the main associated risk factors. The aim of this study was to assess the prevalence of P.

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 ...
