| Outline of Final Research Achievements |
Kog1 is derived from Lactobacillus rhamnosus KO isolated from a patient with no caries experience. Kog1 significantly inhibited the expression of inflammatory cytokines and chemokines induced by LPS of Porhyromonas gingivalis in gingival epithelial cells and fibroblasts. Kog1 highly bound to LPS. It is suggested that Kog1 binds and neutralizes LPS, resulted in the inhibitory effects as with known anti-microbial peptides.
