Proteases produced by Porphyromonas gingivalis , an oral pathogen, are considered important virulence factors and may affect the responses of cells equipped with proteinase-activated receptors. The aim of this study was to investigate the effect of the arginine-specific cysteine protease gingipain-R produced by P. gingivalis on chemokine production by human gingival fibroblasts (HGF) and the Both Lys-gingipain (gingipain-K) and Arg-gingipain (gingipain-R) prolonged plasma TT in a dose- and time-dependent manner, and this was also found with vesicles which are the biological carriers of P. gingivalis proteinases.

In ex vivo studies, it was shown that gingipain K retained its IgG hydrolyzing activity in human plasma despite the high content of natural protease inhibitors; that IgG(1) cleavage products were detected in gingival crevicular fluid samples from patients with severe periodontitis; and that gingipain K treatment of serum samples from patients with high antibody titers against P. gingivalis significantly hindered opsonin-dependent phagocytosis of clinical isolates of P. gingivalis by neutrophils. Porphyromonas gingivalis is a member of the dysbiotic oral microbiome and a "keystone pathogen" that causes severe periodontal disease, which is among the most prevalent infectious diseases. Part of the virulence factors secreted by P. gingivalis are the essential cysteine peptidases gingipain K (Kg … 2019-03-20 · Structural determinants of inhibition of Porphyromonas gingivalis gingipain K by KYT-36, a potent, selective, and bioavailable peptidase inhibitor Abstract.
