Colocalization of Porphyromonas gingivalis with CD4+ T cells in periodontal disease.
Porphyromonas gingivalis, an anaerobic, asaccharolytic gram-negative bacterium, is a causative agent in chronic periodontitis. It has many virulence factors that facilitate infection of the gingiva, but little is known about the local immune cells that respond to this bacterium. The aims of this study were to quantify P. gingivalis in gingival biopsies from patients with periodontitis using las...
متن کاملAltered T-Cell Responses by the Periodontal Pathogen Porphyromonas gingivalis
Several studies support an association between the chronic inflammatory diseases periodontitis and atherosclerosis with a crucial role for the periodontal pathogen Porphyromonas gingivalis. However, the interplay between this pathogen and the adaptive immune system, including T-cells, is sparsely investigated. Here we used Jurkat T-cells to determine the effects of P. gingivalis on T-cell-media...
متن کاملStudy of Porphyromonas gingivalis in periodontal diseases: A systematic review and meta-analysis
Background: The mouth cavity hosts various types of anaerobic bacteria including Porphyromonas gingivalis, which causes periodontal inflammatory diseases. P. gingivalis is a gram-negative oral anaerobe and is considered as a main etiological factor in periodontal diseases. Several studies have reported a relationship between P. gingivalis in individuals with periodontal diseases and a critical ...
متن کاملPresence of Treponema denticola and Porphyromonas gingivalis in children correlated with periodontal disease of their parents.
Considerable evidence exists suggesting that periodontal disease is due to the overgrowth of a finite number of specific bacteria such as Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Treponema denticola, Bacteroides forsythus, and Prevotella intermedia, among others. Three of these organisms-P. gingivalis, T. denticola, and B. forsythus-can be easily detected in plaque sample...
متن کاملHumoral immunity of older adults with periodontal disease to Porphyromonas gingivalis.
The effect of age on the humoral response to Porphyromonas gingivalis was assessed in groups of adults (25 to 54 years and 55 to 74 years) with periodontal disease and compared with that in age-matched healthy controls. To determine whether there was an antibody response against P. gingivalis, we measured serum antibodies against whole cells of P. gingivalis 381, A7A1-28, and W50. In addition, ...
