J Periodontol:共生菌群对脂多糖牙周免疫应答的影响

2018-10-05 MedSci MedSci原创

共生菌群参与成熟免疫系统的发育。然而,尚不清楚共生菌群如何促进针对牙周病原体的免疫应答,包括对脂多糖(LPS)的反应。本研究的目的是评估在无菌(GF)和无特定病原体(SPF)小鼠中局部施用LPS后免疫应答的表达。

共生菌群参与成熟免疫系统的发育。然而,尚不清楚共生菌群如何促进针对牙周病原体的免疫应答,包括对脂多糖(LPS)的反应。本研究的目的是评估在无菌(GF)和无特定病原体(SPF)小鼠中局部施用LPS后免疫应答的表达。

方法:将8周龄的GF和SPF小鼠随机分成4组:基线组(n = 4 /组)和3个实验组(n = 6 /组)。实验组腭龈沟局部应用牙龈卟啉单胞菌LPS(10μg/μL)。在LPS应用(实验前)之前和应用后3小时、24小时或72小时进行取样。通过免疫组织化学评估牙周组织中的中性粒细胞,CD4 +和CD8 + T细胞的数量。通过实时PCR确定编码细胞因子,趋化因子和转录因子的基因的表达。

结果:与实验前的数量相比,SPF小鼠在LPS应用后3小时,牙周组织中CD4 + T细胞的数量增加(p <0.05)。在施用LPS后3小时,SPF小鼠中肿瘤坏死因子-α(Tnf-α)和叉头盒蛋白p3(Foxp3)的基因表达也显着高于GF小鼠(p <0.05)。在GF和SPF小鼠中,中性粒细胞的数量在24小时达到峰值。

与GF小鼠相比,暴露于LPS的SPF小鼠的牙周组织中CD4 + T细胞数量和Tnf-α和Foxp3基因表达增加。
