Dominy et al. have provided robust data linking the brain with the main, or keystone, pathogen (Porphyromonas gingivalis) of periodontitis—or gum disease, as it is commonly known. This bacterium appears to migrate from the mouth to the brain of some individuals as they age, and of a significant proportion of subjects who go onto develop Alzheimer’s disease.

Porphyromonas gingivalis, a gram-negative anaerobe present in subgingival plaque, was identified as a major etiologic agent of chronic periodontitis (Marcotte and Lavoie, 1998). The factors by which Po. gingivalis might express its virulence include lipopolysaccharides, hemagglutinin, fimbriae, and the Arg-X-specific (Rgp) and Lys-X-specific (Kgp) cysteine proteinases (the gingipains) ( Andrian et al., 2004 ).

Porphyromonas gingivalis (P. gingivalis) is a keystone pathogen in periodontitis. However, several clinical studies have revealed an enrichment of P. gingivalis in the stool samples and colorectal mucosa of colorectal cancer patients. Thus, the goal of this study was to determine whether P. gingivalis can promote colorectal cancer progression in vitro. We established an acute infection model

2016-02-01 · Porphyromonas gingivalis, an asaccharolytic bacterium, utilizes amino acids as energy and carbon sources. Since amino acids are incorporated into the bacterial cells mainly as di- and tri-peptides, exopeptidases including dipeptidyl-peptidase (DPP) and tripeptidyl-peptidase are considered to be prerequisite components for their metabolism. Porphyromonas gingivalis (Pg) is a periodontopathic pathogen that may affect MUC5AC‐related mucus hypersecretion along airway epithelial cells. Here, we attempted to establish whether Pg virulence factors (lipopolysaccharide, FimA fimbriae, gingipains) affect MUC5AC in immortalized and primary bronchial cells. Porphyromonas gingivalis is an asaccharolytic, black-pigmented, gram-negative anaerobe that is strongly associated with chronic periodontitis (13), a chronic inflammatory condition affecting tooth-supporting tissues that ultimately results in tooth loss, and may be involved in systemic illnesses, such as atherosclerosis (reviewed in references 28 and 44). Porphyromonas gingivalis, a gram-negative anaerobe present in subgingival plaque, was identified as a major etiologic agent of chronic periodontitis (Marcotte and Lavoie, 1998).

Keywords:porphyromonas gingivalis, arg- and lys-specific cell surface proteinases, virulence, pathogenic mechanism, vaccine Abstract: The gingipains are cell surface Arg- and Lys-specific proteinases of the bacterium Porphyromons gingivalis, which has been associated with periodontitis, a disease that results in the destruction of the teeths supporting tissues.

P. gingivalis cell-surface-located protease/adhesins, the gingipains, have been suggested to be involved in its interactions with several other bacterial species. Gingipains from Porphyromonas gingivalis 18329 Int J Clin Exp Med 2015;8(10):18327-18334 thalmic forceps in a “cuffing” manner, and the endothelium was mechanically removed by scraping with a sterile gauze after opening the media longitudinally. The separated rat aortic media was excised and cut into small pieces Vaccination against P. gingivalis: Many researchers have investigated a group of cell surface carbohydrates designated as K-antigens 199, lipopolysaccharides 200, 201 and various proteins, including fimbriae 202, the 53-KDa and 67K-Da cell surface proteins 203, hemagglutinin 204 and cysteine proteases referred to as gingipains 205, for making a vaccine against P. gingivalis.
