摘要: 目的使用不同的HIV-载体感染人肺动脉平滑肌细胞,并使用HIV慢病毒载体将外源基因转入人肺动脉平滑肌细胞。方法应用ADA/Luc、HXB2/Luc、VSV-G/Luc和VSV-G/GFP感染人肺动脉平滑肌细胞U87.CD4.CCR5和U87.CD4.CX-CR4。结果ADA/Luc和HXB2/Luc均能感染具有相应复合受体的U87.CD4,但不能感染人肺动脉平滑肌细胞。VSV-G/Luc和VSV-G/GFP能有效转导至人肺动脉平滑肌细胞中,于感染第3天,表达VSV-G/GFP的人肺动脉平滑肌细胞的阳性率为18%。结论应用HIV慢病毒载体能够向人肺动脉平滑肌细胞中导入外源基因。

Abstract: Objective To infect human pulmonary artery smooth muscle cells with different HIV-based vectors, and introduce foreign genes into the cells with HIV-based lentivirus vectors.MethodsThe human pulmonary artery smooth muscle cells, U87.CD4.CCR5 and U87.CD4.CXCR4, were infected with ADA/Luc, HXB2/Luc, VSV-G/Luc and VSV-G/GFP.ResultsU87.CD4 with corresponding coreceptors could be infected by ADA/Luc and HXB2/Luc, however, the human pulmonary artery smooth muscle cells could not be infected by ADA/Luc and HXB2/Luc, even pseudotypes. VSV-G/Luc and VSV-G/GFP could be transfered into the human pulmonary artery smooth muscle cells. After 3 days post-infection, the relative proportion of positive cells of human pulmonary artery smooth muscle cells expressing VSV-G/GFP was 18%.ConclusionHIV-based lentivirus vectors can introduce foreign genes into the human pulmonary artery smooth muscle cells.
