The periodontal pathogen Porphyromonas gingivalis produces a unique class of cysteine proteinases termed gingipains that comprises Arg‐gingipain (Rgp) and Lys‐gingipain (Kgp).

In this systematic review authors have evaluated the 2 on periodontal tissue metabolism. 1. Introduction Periodontium is characterized by the tissues that involve and support the teeth such as the gingiva, alveolar mucosa, cementum, periodontal ligament, and alveolar bone. Peri-odontitis, an oral disease which leads to alveolar bone loss, can be mediated by some of the endogenous host enzymes, Many efforts have been made to develop therapeutic agents for Alzheimer’s Disease (AD) based on the amyloid cascade hypothesis, but there is no effective Gingipains play a role in bacterial housekeeping and infection, including amino acid uptake from host proteins and fimbriae maturation.

Growing evidence indi-cates that these 2 types of gingipains synergistically contribute to the entire virulence of the organism and increase the risk of periodontal disease (PD) by disrupt-ing the host immune system and degrading the host tissue and plasma proteins.

Gingipains play a role in bacterial housekeeping and infection, including amino acid uptake from host proteins and fimbriae maturation. Based on the important activities of gingipains in the bacterial infection and the pathogenesis of periodontitis, the bacterial proteinases can be targets for periodontal disease therapy.

The periodontal pathogen Porphyromonas gingivalis produces a unique class of cysteine proteinases termed gingipains that comprises Arg‐gingipain (Rgp) and Lys‐gingipain (Kgp). In addition to their function in virulence, gingipains are also essential for the growth and survival of P. gingivalis in periodontal pockets through the acquisition of amino acids and heme groups. Furthermore, Rgp and Kgp gingipains are critical in processing fimbriae and several bacterial proteins that contribute to hemagglutination, coaggregation, and hemoglobin binding.

same manner. It has been thought that these gingipains play critical roles in the onset of periodontal inflammation through their proteolytic activities, i.e. enhancement of vas-cular permeability by activation of the kallikrein/kinin path-way, dysregulation of plasma clot formation, activation of complement components and modification of neutrophil The study confirmed via animal testing that P. gingivalis can travel from the mouth to the brain and that the related gingipains can destroy brain neurons. These findings are noteworthy in that they suggest a biological mechanism for how periodontal disease bacteria may play a role in the development and progression of Alzheimer’s.
