| Research Abstract |
We previously purified and identified the protein from cell surface component on P. gingivalis, a major periodontal pathogen. This protein was able to induce Toll-like receptor 2 (TLR2)- and TLR4-independent signaling in CHO cells and that this component can be degraded by gingipains. Therefore, we named the protein as gingipain-sensitive ligand A (GslA). P. gingivalis gingipain-null mutant was partially inhibited by antiserum against a recombinant protein expressed from the first one third of gslA. Furthermore, the gslA gene was present in four of seven P. gingivalis strains tested.
