| Outline of Final Research Achievements |
Extracellular DNA and hitone-like DNA binding protein (HLP) play crucial roles in biofilm development and its rigidity. eDNA also induces the morphological transition from yeast to hyphal growth form during Candida albicans biofilm development. MPC-polymer treatment significantly reduced the adherence of Pophyromonas gingivalis, major periodontitis-related pathogen, on oral keratinocytes and inhibited TLR2-mediated IL-8 production by blocking the binding of its specific-ligand in a concentration-dependent manner. This study suggests that eDNA- and HLP-targeting strategies may be applicable to novel treatments for bacterial biofilm-related infectious diseases and MPC-polymer is potentially useful for oral care to prevent oral infection.
