Porphyromonas gingivalis, neuroinflammation and Alzheimer’s disease

Nigerian Journal of Physiological Sciences, 2022
The oral microbiota dysbiosis, as well as lifestyle, geographical location, drug consumption, and dietary habits, are involved in the incidence and progression of dementia, Mild Cognitive Impairment (MCI), and some diseases such as obesity, diabetes, cardiovascular disease, preterm birth, rheumatoid arthritis, cancer, inflammatory bowel disease, and ...

How Porphyromonas gingivalis Navigate the Map: The Effect of Surface Topography on the Adhesion of Porphyromonas gingivalis on Biomaterials

, 2022
The main purpose of this study is to develop an understanding of how Porphyromonas gingivalis responds to subperiosteal implant surface topography. A literature review was drawn from various electronic databases from 2000 to 2021.

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 ...

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 ...

Characterization of the  - and  -Mannosidases of Porphyromonas gingivalis [PDF]

Journal of Bacteriology, 2013
Mannose is an important sugar in the biology of the Gram-negative bacterium Porphyromonas gingivalis. It is a major component of the oligosaccharides attached to the Arg-gingipain cysteine proteases, the repeating units of an acidic lipopolysaccharide (A-LPS), and the core regions of both types of LPS produced by the organism (O-LPS and A-LPS) and a ...

Porphyromonas Gingivalis Sialidase Reshapes Gut Microbiota And Systemic Immunity

International Dental Journal
Aim or purpose: Porphyromonas gingivalis can alter the gut microbiota and serum metabolites. However, its sialidase in modulating gut microbiota composition, host metabolism, and immune responses remains unexplored.

Roles of Oral Bacteria in Cardiovascular Diseases — From Molecular Mechanisms to Clinical Cases: Involvement of Porphyromonas gingivalis in the Development of Human Aortic Aneurysm

Journal of Pharmacological Sciences, 2010
Accumulating evidence suggests the involvement of Porphyromonas gingivalis (P. gingivalis), a periodontal pathogen, in cardiovascular diseases. Clinical specimens of aneurysmal tissue and dental plaque collected from patients infected with or without P ...

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 test of Peperomia pellucida (L.) Kunth extract against Porphyromonas Gingivalis as a potential herb for periodontitis: a laboratory experiment

Padjadjaran Journal of Dentistry, 2023
Introduction: Periodontitis is a multifactorial inflammatory disease which is generally caused by plaque accumulation. Many studies have shown that Porphyromonas gingivalis (Pg) is the main etiological agent that contributes to chronic periodontitis ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.
