Research Abstract |
NKT cell function on periodontal destruction was analyzed using mouse periodontitis model which was chronically and orally infected with periodontopathic bacteria, Porphyromonas gingivalis. In CD1d-/-mice alveolar bone resorption was inhibited. On the other hand, NKT cell-activated mice(stimulated withα-galactosylceramide) demonstrated higher level of alveolar bone resorption. In NKT cell-activated mice, NKT cells produced more IL-4 than IFN-γ. Furthermore, serum levels of P. gingivalis specific antibody and RANKL was upregulated. Those results suggest that NKT cells promote periodontal destruction through induction of Th2 response.
