| Outline of Final Research Achievements |
High mobility group box 1 (HMGB 1) is a DNA binding protein, but it plays as an inflammatory mediator when it is secreted extracellularly due to tissue damage or necrosis. The detailed mechanism of how HMGB1 affects the progress of periodontitis has not been elucidated. As a result of this study, it was revealed that HMGB1 was produced from gingival epithelial cells, macrophage-like cells by inflammatory stimulation. In addition, by administering anti-HMGB 1 antibody to periodontitis model mice, inflammation due to periodontitis is suppressed. As a result, migration of neutrophils, production of IL-1βwere suppressed and the bone resorption by periodontitis was suppressed.
