Background Porphyromonas gingivalis, a periodontal pathogen, expresses a number of virulence factors, including long (FimA) and short (Mfa) fimbriae as well as gingipains comprised of arginine-specific (Rgp) and lysine-specific (Kgp) cysteine proteinases.

Conclusion. Porphyromonas gingivalis has the potential to change the expression of lipoproteins in blood, which may represent a crucial link between periodontitis and CVD. Peter L.W. Yun, Arthur A. DeCarlo, Cheryl C. Chapple, Charles A. Collyer, Neil Hunter, Binding of Porphyromonas gingivalis gingipains to human CD4+ T cells preferentially down-regulates surface CD2 and CD4 with little affect on co-stimulatory molecule expression, Microbial Pathogenesis, 10.1016/j.micpath.2005.01.001, 38, 2-3, (85-96), (2005). Porphyromonas gingivalis (P. gingivalis) is a major oral pathogen and associated with periodontal diseases including periodontitis and alveolar bone loss. In this review, we indicate that two virulence factors, which are hemoglobin receptor protein (HbR) and cysteine proteases “gingipains”, expressed by P. gingivalis have novel functions on the pathogenicity of P. gingivalis . P. gingivalis is non-motile, anaerobic and asaccharolytic (i.e.

Takafumi Kato. Tamotsu Yoshimori. Keystone pathogens, such as Porphyromonas gingivalis (P. gingivalis), facilitate the subversion of the host immune response through polymicrobial synergy allowing for the growth of both themselves and other dysbiotic species [10,11,12]. Gingipains, a group of arginine or lysine specific cysteine proteinases (also known as RgpA, RgpB and Kgp), have been recognized as major virulence factors in Porphyromonas gingivalis. This bacterium is one of a handful of pathogens that cause chronic periodontitis.

310, 168–174. doi: 10.1111/j.1574-6968.2010.02059.x Periodontitis is a multifactorial disease, with participation of bacterial, environmental, and host factors. It results from synergistic and dysbiotic multispecies microorganisms, critical “keystone pathogens,” affecting the whole bacterial community. The purpose of this study was to review the role of Porphyromonas gingivalis in the immunopathogenesis of chronic Cysteine proteinase with a strong preference for substrates with Lys in the P1 position.

Gingipains from Porphyromonas gingivalis play a significant role in induction and regulation of CXCL8 in THP-1 cells. Jayaprakash, Kartheyaene . Örebro University, School of Health and Medical Sciences, Örebro University, Sweden. ORCID iD: 0000-0001-7105-0425. Khalaf, Hazem .

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 Studies have shown that Porphyromonas gingivalis surface structures play an important role in the life cycle of the oral anaerobe. In particular, cysteine proteases, fimbriae, membrane vesicles (MVs), and surface polysaccharides have been of primary interest.
