Porphyromonas gingivalis and rheumatoid arthritis

Current Opinion in Rheumatology, 2019
Purpose of review To explore the pathogenic association between periodontal disease and rheumatoid arthritis focusing on the role of Porphyromonas gingivalis. Recent findings In the last decades our knowledge about the pathogenesis of rheumatoid arthritis substantially changed ...

Proteases and Collagenases of Porphyromonas Gingivalis

Advances in Dental Research, 1995
Proteases expressed by Porphyromonas gingivalis have been considered as potential virulence factors for these periodontopathic micro-organisms. The introduction of molecular genetic approaches to study these enzymes has clearly demonstrated that these organisms are capable of expressing multiple distinct proteases.

Citrullination in periodontium is associated with Porphyromonas gingivalis

Archives of Oral Biology, 2020
To analyse the citrulline level in the periodontium in association with the presence of or antibody levels against Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis.Gingival crevicular fluid (GCF), subgingival biofilm and blood serum were sampled from 98 subjects (26 with RA, 72 without RA (NoRA)).

Genetic Manipulation of Porphyromonas gingivalis

Current Protocols in Microbiology, 2007
AbstractPorphyromonas gingivalis, an oral anaerobic bacterium, is an important etiological agent of periodontal disease and may contribute to cardiovascular disease, preterm birth, and diabetes as well. Therefore, genetic studies are of crucial importance in investigating molecular mechanisms of P. gingivalis virulence. Although molecular genetic tools

Surface components of Porphyromonas gingivalis

Journal of Periodontal Research, 2009
Background and Objective:  Research on Porphyromonas gingivalis, a periodontopathogen, has provided a tremendous amount of information over the last 20 years, which may exceed in part than that on other closely related members in terms of phylogenetic as well as proteomic criteria, including Bacteroides fragilis and B.

Role for Porphyromonas gingivalis in the progression of atherosclerosis

Medical Hypotheses, 2009
An association between atherosclerosis and Porphyromonas gingivalis (P. gingivalis), a major periodontopathogen, has been shown. However, the question of whether this relationship is causal or coincidental still exist. Many individuals with evidence of atherosclerosis demonstrate seropositivity to this pathogen.

A Statistical Approach to the Ecology of Porphyromonas gingivalis

Journal of Dental Research, 1992
Previous studies have suggested that infections with Porphyromonas gingivalis, associated with periodontal disease, may consist of one clonal type. It has also been shown that each individual patient carries a unique clonal type of P. gingivalis, as assessed by DNA fingerprinting.

Mechanisms of evasion of complement by Porphyromonas gingivalis

Frontiers in Bioscience, 2008
The complement system is an important host response to invading bacteria. Activation leads to deposition on the bacterial surface of C3b and its' inactivation products and phagocytosis of the opsonised bacteria by host cells. Alternatively the entire complement pathway including terminal components C5b-9 may be activated on the cell surface which gives

Subgingival colonization by Porphyromonas gingivalis

Oral Microbiology and Immunology, 2000
Porphyromonas gingivalis, a gram‐negative anaerobe, is a major causative agent in the initiation and progression of severe forms of periodontal disease. In order to cause periodontal disease, P. gingivalis must colonize the subgingival region, a process that involves several distinct steps and multiple gene products.

Preferential Utilization of Dipeptides by Porphyromonas gingivalis

Journal of Dental Research, 2001
Although Porphyromonas gingivalis is known to utilize peptides preferentially, instead of free amino acids, as the source of energy and cell material, there is only limited information on what sizes and kinds of peptide this bacterium preferentially utilizes.
