| Research Abstract |
Proliferative responses of keratinocytes in the skin and the gingiva that overexpressed an immunoregulatory molecule B7-H1 were accelerated. Early inflammatory skin responses were suppressed by B7-H1 on keratinocytes in a PD-1-dependent manner, but the inflammatory responses in the gingiva were impaired. A murine model of periodontitis was induced by a TDC60 strain of Prophyromonas gingivalis. Serum titers of TDC60-specific IgG were markedly elevated in the mice that exhibited severe alveolar bone loss.
