| Outline of Final Research Achievements |
It has been suggested that oxidatively modified proteins are associated with the pathogenesis of chronic inflammatory diseases and infectious diseases. However, little is known about how the oxidative modification of proteins contributes to the pathogenesis of periodontal diseases. In this study, we explored oxidatively modified proteins in mammalian cells by an inclusive analyzing technique and examined the role of oxidatively modified proteins in the pathogenesis of periodontal diseases. We examined oxidatively modified proteins in the macrophage cell line RAW264 cyclopaedically and found that a small G-protein, Rab5, was s-nitrosylated in the cells. S-nitrosylated Rab5 enhanced bacterial pagocytosis in RAW264 cells. S-nitrosylation of proteins may be an important mechanism to protect periodontal tissues from infection with periodontopathic bacteria.
