Porphyromonas gingivalis is a keystone periodontal pathogen that has been associated with autoimmune disorders. The cell surface proteases Lys-gingipain (Kgp) and Arg-gingipains (RgpA and RgpB) are major virulence factors, and their proteolytic activity is enhanced by small peptides such as glycylglycine (GlyGly). The reaction kinetics suggested that GlyGly may function as an acceptor molecule Porphyromonas gingivalis, THP-1 cells, Gingipains, Mutants, CXCL8 degradation National Category Microbiology Research subject Microbiology Identifiers urn:nbn:se:oru:diva-36171 (URN) 10.1186/1471-2180-14-193 (DOI) 000339837900001 () Porphyromonas gingivalis, the etiological agent of periodontal disease, is an anaerobe that requires iron in the form of heme for growth. This chapter discusses the roles of specific outer membrane proteins and gingipains in heme accumulation by P.gingivalis. 4 Porphyromonas gingivalis , a gram negative anaerobe, which is implicated in the 5 etiology of active periodontitis, secretes degradative enzymes (gingipains) and 6 sheds proinflammatory mediators (e.g.

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. Porphyromonas gingivalis is considered a major pathogen of chronic periodontitis, which also may be implicated with systemic diseases such as atherosclerosis. Secreted cysteine proteases, gingipains Rgp and Kgp, are essential for P. gingivalis virulence.

P. gingivalis is part of the predominant An enzyme called gingipains, which the Porphyromonas gingivalis (P. gingivalis) bacteria gives off, is the "main cause of Alzheimer's disease," Dr. Steve Dominy, study author and associate 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.
