| Research Abstract |
In this study, we investigated expression pattern of inflammasome in periodontal tissue and cells to assess the involvement of inflammasome in periodontal tissue homeostasis, destruction and regeneration. It was shown that inflammasome-associated molecules are expressed in periodontal tissues and cells in normal conditions and these expressions are up-regulated in inflammatory conditions. Periodontal ligament associated extracellular matrix (PDL-ECM) proteins show the interaction with inflammasome, suggesting the regulation of tissue-homeostasis and inflammatory responses by PDL-ECM-inflammasome pathway.
