Outline of Final Research Achievements

Inflammatory cacpases 1,4,5 are involved in production of interleukin-1β and proptosis cell death in inflammatory diseases, and contribute to the clearance of invasive bacterial pathogens. Therefore, we investigated the role of capases in periodontal inflammation in rat experimental periodontal models. We used anti-diabetic drug, gluburide, which is act as NLRP3 inhibitor, to inhibit the activation of caspase 1. The rats given glyburide exhibit significantly lower number of inflammatory cells and osteoclasts and bone resorption compared with control. This results indicate that caspase 1 play an important role in periodontal inflammatory responses and alveolar bone resorption.
