[Understanding and treatment strategy of the pathogenesis of periodontal disease based on chronic inflammation].
Prolonged inflammation continuously promotes the infiltration of macrophages in the organization and chronically induces the production of pro-inflammatory cytokines such as TNF and IL-1. In periodontal tissues, these inflammatory cytokines enhance the differentiation and activity of osteoclasts, which cause destruction of the alveolar bone. Therefore, inhibition of inflammatory cytokine production leads to the prevention or treatment of periodontal disease. IL-1 is a pro-inflammatory cytokine that strongly enhances the bone-resorbing activity of osteoclasts. Elucidation of mechanisms for the production of IL-1 is critical for understanding the pathogenesis of periodontal disease. This paper reviews recent findings of the molecular mechanisms regulating IL-1 production and focuses on inflammasome.
