Research Abstract |
In this study we have investigated the effects of S1P, bioactive lipid mediator, on inflammatory responses of gingival epithelial cells. S1P receptors, S1P2 and S1P3, are expressed in gingival epithelial cells. S1P increased to produce IL-8 from gingival epithelial cells in a dose-dependent manner. S1P-induced IL-8 production upregulated synergistically in the presence of HMGB-1 or Poly(I:C). S1P-induced IL-8 induction was suppressed in S1P2/S1P3 knockdown gingival epithelial cells. These findings suggest that S1P induce inflammation in gingival epithelial cells via S1P2/S1P3.
