Sci Rep:研究揭示人牙周膜干细胞对IFN-γ和TLR激动剂的反应

2017-10-22 MedSci MedSci原创

与其他组织的间充质干细胞类似,牙周膜干细胞具有免疫调节特性,可受不同的细胞因子调节,特别是通过干扰素-γ(IFN-γ)调节。相比之下很少有研究探究了通道样受体配体对这些细胞的免疫调节特性的影响。本研究中,研究人员探究了人牙周膜干细胞(hPDLSCs)对IFN-γ和toll样受体(TLR)激动剂同时刺激的反应。探究了吲哚胺-2,3-双加氧酶-1(IDO-1)、白介素(IL)-6、IL-8和单核细胞趋

与其他组织的间充质干细胞类似,牙周膜干细胞具有免疫调节特性,可受不同的细胞因子调节,特别是通过干扰素-γ(IFN-γ)调节。相比之下很少有研究探究了通道样受体配体对这些细胞的免疫调节特性的影响。

本研究中,研究人员探究了人牙周膜干细胞(hPDLSCs)对IFN-γ和toll样受体(TLR)激动剂同时刺激的反应。探究了吲哚胺-2,3-双加氧酶-1(IDO-1)、白介素(IL)-6、IL-8和单核细胞趋化蛋白1(MCP-1)的表达。

结果显示,基因和蛋白质水平IDO-1的表达因IFN-γ刺激而上调。TLR2激动剂Pam3CSK4诱导IDO-1的基因表达,但对蛋白的表达并没有影响。Pam3CSK4进一步增强IFN-γ诱导的IDO-1蛋白的表达。TLR-4激动剂大肠杆菌LPS对IFN-γ诱导的IDO-1蛋白的表达无明显影响。由TLR激动剂可诱导IL-6、IL-8和MCP-1的产生。TLR激动剂诱导这些蛋白的产生不受IFN-γ的影响。

总之,该研究结果表明,hPDLSCs中IFN-γ和TLR2应答之间具有潜在的相互作用,可能参与调节炎性疾病中的免疫应答,特别是牙周炎。

研究发现高糖环境中miR-31抑制PDLSCs成骨分化的机制

糖尿病是一种慢性代谢性疾病,影响骨重塑。越来越多的证据表明,miRNAs与干细胞的成骨分化有关。然而,糖尿病引起的HG条件与牙周膜干细胞(PDLSCs)成骨分化能力受损之间潜在的联系机制仍不清楚。在这项研究中,研究人员发现,糖尿病小鼠牙周韧带中miR-31的水平升高则会表现出更大程度的骨丧失。在体外,高糖环境中,miR-31的高表达与PDLSCs成骨细胞分化能力受损相关。此外,miR-31抑制剂可
