摘要/Abstract

摘要： 目的探讨他米巴罗汀（Tamibarotene，Am80）对经牙龈卟啉单胞菌（Porphyromonas gingivalis，P.gingivalis）抗原刺激后的小鼠单核巨噬细胞RAW264.7的影响。方法采用P.gingivalis抗原刺激RAW264.7细胞，分别用不同浓度的Am80进行干预;相差显微镜下观察各组细胞生长情况；MTS法检测不同浓度Am80对抗原刺激RAW264.7细胞的增殖情况；酶联免疫吸附法（ELISA）检测细胞培养上清中抗炎因子IL-10的含量。结果 10 nmol/L Am80能够显著抑制P.gingivalis抗原刺激RAW264.7细胞的增殖分化（P<0.001）；Am80（10 nmol/L）致抗原刺激的细胞IL-10的分泌量显著增加（P<0.05）；倒置相差显微镜下观察显示Am80抑制抗原刺激细胞的增殖分化。结论 Am80（10 nmol/L）时可显著促进P.gingivalis抗原诱导小鼠巨噬细胞分泌抗炎因子IL-10，并可能由此抑制P.gingivalis抗原诱导的炎症反应。

Abstract: Objective To investigate the effect of Am80 on murine macrophage RAW264.7 after P.gingivalis antigen stimulation.Methods RAW264.7 cells were stimulated by P.gingivalis antigen and treated with different concentrations of Am80.Cell growth was observed in each group under a phase contrast microscope; the proliferation of antigen-stimulated RAW264.7 cells with different concentrations of Am80 were detected by MTS assay; enzyme-linked immunosorbent assay(ELISA) was used to detect anti-inflammatory factor levels of IL-10 in cell culture supernatant.Results 10 nmol/L Am80 significantly inhibited the proliferation and differentiation of P.gingivalis antigen-stimulated RAW264.7 cells（P<0.001）while Am80 (10 nmol/L) significantly increased the secretion of IL-10 by antigen-stimulated cells (P<0.05); inverted phase contrast microscope showed that Am80 inhibited antigen-stimulated proliferation and differentiation of RAW264.7 cells.Conclusions Am80 (10 nmol/L) can significantly promote P.gingivalis antigen-induced murine macrophages secretion of anti-inflammatory cytokine IL-10,and it may inhibit P.gingivalis antigen-induced inflammation.
