Immunization with gingipain A hemagglutinin domain of Porphyromonas gingivalis induces IgM antibodies binding to malondialdehyde-acetaldehyde modified 

The effect of P. gingivalis strains on epithelial cell detachment was investigated using the HO‐1‐N‐1 and Ca9‐22 epithelial cell lines. 2020-01-21 2003-04-01 Gingipain inhibition reduced the bacterial load of an established P. gingivalis brain infection, blocked A 1–42 pro- duction, reduced neuroinflammation, and rescued neurons in the hippocampus. gingipain has been observed to possess hemolytic activity (43), the role of Lys-gingipain in hemolysis remains unknown. Re-cently, a hemoglobin binding protein called HbR, intrageni-cally encoded by the rgpA, kgp, and hagA genes, has been identified (35). In addition, the Lys-gingipain has shown he-moglobin binding activity (28).

HRgpA (95 kDa) and RgpB (50 kDa), products of 2 distinct but related genes, rgpA and rgpB, respectively, are specific for Arg-Xaa peptide bonds. Kgp, a product of the kgp gene, is specific for Lys-Xaa bonds. Growth studies with site-directed gingipain-deficient mutants ofP. gingivalis revealed that inactivation of both gingipains prevents growth, whereas inactivation of either Arg- or Lys-gingipain activity extended the doubling times to 33 or 13 h, respectively, compared to 9 h for the parent strain.

gingipain inhibitors. (B) Proteolysis of cellular ApoE was detected in infected cells at MOI 50. Incubation of P.g prior to infection with the lysine-gingipain (Kgp) inhibitor COR388 protected ApoE protein from degradation. However, this protective effect was not seen with the RgpB inhibitor COR613. This data suggests that

They are produced as pre-proproteins which mature into ARGININE and LYSINE specific endopeptidases.

Two of the recombinant antigens that we identified, Lys-gingipain (Kgp) and Arg-gingipain (RgpA), are strong cysteine proteases that are capable of self-digestion and, thus, are unstable.

In addition, the Lys-gingipain has shown he-moglobin binding activity (28). We now show that the lysine-specific gingipain (gingipain K; KGP) is also biosynthesized as a polyprotein precursor that contains a proteinase domain that is 22% homologous to the proteinase domain of RGP-1 and multiple adhesin domains.

The GAIN (GingipAIN Inhibitor for Treatment of Alzheimer’s Disease) Trial is based on a growing body of scientific evidence that the bacteria P. gingivalis, most commonly associated with degenerative gum disease, can infect the brain and cause Alzheimer’s disease.

Porphyromonas Gingivalis is the key bacteria to chronic gum disease, according to recent research if you bleed when you brush your teeth you may want to get that looked at.

gingivalis, Pg) and if these effects are through complement component 5a (C5a) pathway. Gingipain inhibitors may also help treat systemic disorders that are associated with periodontitis, including cardiovascular disease, rheumatoid arthritis, aspiration pneumonia, pre-term birth 2021-02-18 · We were able to detect several of the predicted hemoglobin fragments rendered by digestion with purified Lys-gingipain. Thus, we postulate that the Lys-gingipain of P. gingivalis is a hemoglobinase which plays a role in heme and iron uptake by effecting the accumulation of FePPIX on the bacterial cell surface.

This Recombinant Porphyromonas gingivalis Gingipain R1 (rgpA) with N-terminal 6xHis-tags is a partial protein expressed in yeast. Its encoding region corresponds to 228-720aa of rgpA of Porphyromonas gingivalis-origin. This recombinant rgpA protein was validated …

The investigators, including Stephen Dominy, MD, the chief scientific officer of Cortexyme, which has developed a gingipain inhibitor, CORE-388, identified the pathogen in the brains of patients with Alzheimer disease, as well as the organism’s gingipains—lysine-gingipain (Kgp), arginine-gingipain A (RgpA), and arginine-gingipain B (RgpB)—in the neurons of these patients. Gingipain not only bestows gum-destroying powers to P. gingivalis, the protease is also neurotoxic, the researchers claim. It killed neurons in culture and upon injection into mouse hippocampus, but its deadly action was blocked by small-molecule inhibitors.

PMCID: PMC93978 PMID: 10438761 2008-07-01 · Proteolytically cleaved into a catalytic subunit and three adhesins. Arg-gingipain is involved in this post-translational processing (By similarity).
