Why Verily, others ponied up $76M for this company's new . 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. Gingipains are trypsin-like cysteine proteinases produced by Porphyromonas gingivalis, a major causative bacterium of adult periodontitis.

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. Stephen Dominy, MD, the chief scientific officer of Cortexyme. Stephen Dominy, MD. Recently, research has suggested that Alzheimer disease pathology could be driven in part by Porphyromonas gingivalis ( P. gingivalis ), an infectious agent involved in the development of chronic gum disease.
The gingipains are cell surface Arg- and Lys-specific proteinases of the bacterium Porphyromons gingivalis, which has been associated with periodontitis, a disease that results in the destruction of the teeth's supporting tissues. The proteinases are encoded by three genes designated rgpA, rgpB and kgp.

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.
Show full The anaerobic bacterium, Porphyromonas gingivalis, is This organism produces potent cysteine proteases known as gingipains, which have specificity for cleavage after arginine or lysine residues. The lysine-specific Porphyromonas gingivalis is known to produce a unique class of cysteine proteinases, termed gingipains. They consist of Arg-gingipain (Rgp) and Lys- gingipain ( Porphyromonas gingivalis, a major pathogen of chronic periodontitis, produces virulence factors that include gingipains, a family of cysteine proteases (Chen et al., Porphyromonas gingivalis, the major etiologic agent of chronic periodontitis, produces a broad spectrum of virulence factors, including Arg- and Lys-gingipain Dec 9, 2020 Background: The cell-surface cysteine proteinases RgpA, RgpB (Arg-gingipain), and Kgp (Lys-gingipain) are major virulence factors of P. Periodontitis is a biofilm-associated irreversible inflammation of the periodontal tissues.
