title: Interleukin-10 receptor expression in human dental pulp cells in response to lipopolysaccharide from Prevotella intermedia.
abstract: Interleukin-10 receptor (IL-10R) expression in human, dental pulp, fibroblast cultures was investigated by using the reverse transcriptase-polymerase chain reaction (RT-PCR) technique. After exposure to lipopolysaccharide (LPS) from Prevotella intermedia, the IL-10R mRNA levels increased after 4 h, peaked at 7 h, and dropped back to the unstimulated level at 24 h. Maximal production of the IL-10R protein in dental pulp fibroblast cultures was detected by Western blot analysis after 12 h of LPS stimulation. In contrast, the human skin fibroblast (SF-MA) and human monocyte (U937) cell lines expressed IL-10R mRNA. Anti-CD14 antibodies inhibited P. intermedia LPS-induced IL-10R mRNA expression. These results indicate that P. intermedia LPS induces IL-10R gene expression in human, dental pulp fibroblasts in vitro.
