Role of Porphyromonas gingivalis gingipains in multi-species biofilm formation Kai Bao1, Georgios N Belibasakis2, Thomas Thurnheer2, Joseph Aduse-Opoku3, Michael A Curtis3 and Nagihan Bostanci1* Abstract Background: Periodontal diseases are polymicrobial diseases that cause the inflammatory destruction of the tooth-supporting (periodontal) tissues. Se hela listan på frontiersin.org It is worth mentioning that since periodontal diseases have been associated with COPD aggravation [[12, 13]], whereas COPD is linked to aspiration pneumonia occurrence [], and similarly, Pg gingipains were found to stimulate aspiration pneumonia []. We postulate that Pg gingipains may play a significant role in aggravating COPD. N2 - Porphyromonas gingivalis (P. gingivalis), a gram-negative anaerobe, is involved in the pathogenesis of periodontal disease, and is found frequently in the subgingival flora in patients with periodontitis.

Gingipains in periodontal disease

Periodontal ( gum) diseases including gingivitis (inflammation of the gums) and periodontitis important role in infection-induced periodontal disease.12, 13 Many groups: arginine gingipains (Rgp), which include RgpA and RgpB, and lysine. 82. Poor oral hygiene is the major cause of periodontal disease and gingivitis1,2. Take a closer look at the causes and mechanisms behind the condition, with a av C Åhman-Persson · 2020 — growth and gingipain activity in different strains of Porphyromonas gingivalis. There is also a high genetic factor that predisposes to periodontal disease and Periodontal pathogens, including Porphyromonas gingivalis, can form biofilms and suggests gingipains as targets for diagnosis and treatment of periodontitis. Sammanfattning : Periodontitis is a chronic inflammatory disease caused by exaggerated host immune responses to dysregulated microbiota in dental biofilms RANKL, kappa-b ligand, periodontal-disease, actinobacillus-actinomycetemcomitans, bone-resorption, marrow cultures, macrophages, gingipains, rankl.

Based on the important activities of gingipains in the bacterial infection and the pathogenesis of periodontitis, the bacterial proteinases can be targets for periodontal disease therapy. Gingipains play a role in bacterial housekeeping and infection, including amino acid uptake from host proteins and fimbriae maturation.

Lipoprotein modifications by gingipains of Porphyromonas gingivalis. J Lönn, S Modified lipoproteins in periodontitis: a link to cardiovascular disease?

The study, published in the journal Science Advances, uncovered a potential link between P. gingivalis, the bacteria associated with periodontal disease (commonly known as gum disease) and Alzheimer’s. Antibiotics can help reduce the prevalence and severity of periodontal disease. 5 Orally administered antibiotics, such as tetracyclines, which are concentrated in the gingival crevicular fluid of the periodontal pockets, have been particularly useful as adjuncts in the treatment of some types of periodontitis. 5

P. gingivalis produces a variety of virulence factors including gingipains and fimbriae. Periodontitis and coronary artery disease : Studies on the association

2001 Aug;46(11 Suppl):1781-8. [Pathophysiological roles of two types of gingipains in periodontal diseases]. [Article in Japanese] activity of gingipains R as a result of antibody recognition of a processing site on the gingipain R precursor. Periodontal diseases are a group of infections that lead to inflammation of the gingivae, destruction of the periodontal tissues, loss of alveolar bone, and in severe cases, exfoliation of teeth [1]. Periodontal experts stress the importance of gum health in older adults and other at-risk groups . CHICAGO – JANUARY 28, 2019 – A recent study has periodontists, experts in the treatment, diagnosis, and prevention of periodontal disease, encouraging patients to maintain gum health in an effort to reduce their Alzheimer’s disease risk. The study, published in the journal Science Advances 2019-11-07 Yamamoto K, Baba A, Okamoto K, Kadowaki T. Pathophysiological roles of two types of gingipains in periodontal diseases.

Porphyromonas gingivalis is one of the bacteria implicated in the biofilm formation of bacterial plaque, and plays an important role in the progression of periodontal disease. In this systematic review authors have evaluated the Recent studies have revealed that microglial cathepsin B is increasingly induced by lipopolysaccharide of Porphylomonas gingivalis, a major pathogen of periodontal disease. Moreover, gingipains produced by P. gingivalis play critical roles in neuroinflammation mediated by microglia and cognitive decline in mice. Background: Porphyromonas gingivalis (P. gingivalis) and its gingipain virulence factors have been identified as pathogenic effectors in Alzheimer’s disease (AD).In a recent study we demonstrated the presence of gingipains in over 90% of postmortem AD brains, with gingipains localizing to the cytoplasm of neurons.

Gingipains play a role in bacterial housekeeping and infection, including amino acid uptake from host proteins and fimbriae maturation. Based on the important activities of gingipains in the bacterial infection and the pathogenesis of periodontitis, the bacterial proteinases can be targets for periodontal disease therapy.

New diagnostic strategies for periodontitis and associated life-threatening systemic conditions such as cardiovascular disease (CVD) are greatly needed both from a health mainly by expressing a high proteolytic activity through gingipains.
