FoxO3a是FoxO转录因子家族成员之一,它参与自噬的转录调控。这篇研究的目的是为了探讨FoxO3a调节的自噬对人的感染牙髓和脂多糖培养的mDPC6T细胞的抗炎功效。

FoxO3a是FoxO转录因子家族成员之一,它参与自噬的转录调控。这篇研究的目的是为了探讨FoxO3a调节的自噬对人的感染牙髓和脂多糖培养的mDPC6T细胞的抗炎功效。

研究通过免疫组化和Western blot检测龋齿和牙髓炎状态下人牙髓细胞的FoxO3a和自噬标志物的表达情况。另外,研究对mDPC6T细胞施加脂多糖刺激在体外培养不同时间观察上述指标变化。随后,研究通过免疫荧光观察FoxO3a的核转运,并通过miRNA技术敲除FoxO3a观察和评估FoxO3a和自噬之间的潜在联系。

结果显示,在人龋齿和牙髓炎样本中提取的成牙本质细胞中,FoxO3a和自噬蛋白均表达上调。另外,研发发现,FoxO3a的核转运增强与炎症进程呈正相关。体外研究表明,脂多糖刺激6小时会增加FoxO3a的核转运以及激活mDPC6T细胞的自噬反应。并且,敲除FoxO3a会抑制自噬。

结论:研究表明,FoxO3a可能对自噬活性起到重要作用并且维持炎症成牙本质细胞的胞内动态平衡。
