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, the keystone pathogen in chronic periodontitis, was identified in the brain of Alzheimer's disease patients. Toxic proteases from the bacterium called gingipains were also identified in the brain of Alzheimer's patients, and levels correlated with tau and ubiquitin pathology.

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

A. Amano. 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].

gingivalis) bacteria gives off, is the "main cause of Alzheimer's disease," Dr. Steve Dominy, study author and associate Gingipains, a class of P. gingivalis proteases, are found in association with neurons, tau tangles, and beta‐amyloid in specimens from the brains of individuals with AD. The brains of mice orally infected with P. gingivalis show evidence of P. gingivalis infiltration, along with various neuropathological hallmarks of AD. 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. Dominy et al.
