Research Abstract

Objectives: IL-33 is involved in Th2-mediated immune responses. We investigated the roles of IL-33 in the gingival inflammation. Methods: WT and IL-33 KO mice received LPS-injection into the gingiva and gingival inflammatory responses were evaluated. Results/Discussion: LPS-injection into gingiva enhanced IL-33 mRNA expression in WT mice. LPS induced inflammatory cytokine mRNA expression levels (IL-1b and TNFa) in IL-33KO mice were higher than wild-type mice. Assessment of alveolar bone loss after LPS injection showed a greater bone loss in both mice as compared with control PBS-injected groups, but IL-33 KO mice showed a significantly higher bone loss. Our results suggest protective roles of IL-33 in early gingival inflammatory responses and chronic alveolar bone loss.
