摘要 目的:构建重组人T细胞转录因子T-bet穿梭载体,研究其在人鼻黏膜上皮细胞(Nasal Mucosa EpithelialCell,NMEC)中的表达,探讨其在儿童变应性鼻炎治疗中的意义。方法:采用RT-PCR方法从健康人PBMC总RNA中扩增出转录因子T-bet的cDNA序列,从而构建成重组穿梭载体pDC316T-bet;采用阳离子脂质体介导将重组穿梭载体pDC316T-bet转染至体外培养的人NMEC。RT-PCR半定量检测T-bet mRNA含量。结果:成功构建重组人T-bet穿梭载体pDC316T-bet。mRNA水平检测,T-bet在转染的人NMEC有稳定的表达。结论:重组穿梭载体pDC316T-bet可转染T-bet基因在体外培养的人NMEC内稳定表达。
