Arg-gingipains (RgpA and RgpB) and Lys-gingipain (Kgp) are responsible for the majority of bacterial proteolytic activity and play essential roles in bacterial virulence. Therefore, gingipains are often considered as therapeutic targets.

2 The secretion of gingipain proteases is part of the asaccharolytic metabolism of P. gingivalis, and Pretreatment of mice with gingipain inhibitors protected their hippocampal neurons from the neurotoxic effects of injecting gingipain directly into the hippocampus. Furthermore, gingipain inhibitors protected the cultured cells from the toxic effects of P. gingivalis , whereas antibiotics, such as moxifloxacin and doxycycline, or semagacestat, a drug that inhibits the production of beta The periodontal pathogen Porphyromonas gingivalis produces a unique class of cysteine proteinases termed gingipains that comprises Arg‐gingipain (Rgp) and Lys‐gingipain (Kgp). 2016-04-08 · gingivalis gingipain-null mutant KDP136 did not induce IL-33 expression. A small interfering RNA for protease-activated receptor-2 (PAR-2) as well as inhibitors of phospholipase C, p38 and NF-κB inhibited the expression of IL-33 induced by P. gingivalis.

Porphyromonas gingivalis, a bacterium associated with active chronic periodontitis lesions, produces several proteolytic enzymes that are thought to be involved in host colonization, perturbation of the immune system, and tissue destruction. 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. 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.

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.
