Lentiviral vectors have proven to be valuable tools for in vitro and in vivo gene delivery because they can transduce dividing and non-dividing cells efficiently, and mediate long-term gene expression. Pseudotyping of lentiviral vectors with envelope proteins other than VSV-G has resulted in enhanced transduction of certain cell types and tissues. In order to improve lentiviral vector-based gene therapy for peripheral neuroectodermal and brain tumors, we compared the efficiency of eight different lentivirus pseudotypes in transducing neuronal and glial tumor cell lines. Here, lentiviral vectors pseudotyped with the envelopes from human foamy virus, rabies, Mokola or amphotropic murine leukemia virus displayed the highest transduction efficiency in neuroblastomas, whereas pseudotyping with the lymphocytic choriomeningitis virus glycoprotein from strain Armstrong 53b resulted in the highest transduction efficiency in gliomas.
慢病毒载体已被证明是用于体外和体内基因递送的有价值工具,因为它们可以高效转导分裂细胞和非分裂细胞,并介导长期基因表达。用除VSV-G以外的包膜蛋白对慢病毒载体进行假型化已导致某些细胞类型和组织的转导增强。为了改进基于慢病毒载体的外周神经外胚层肿瘤和脑肿瘤基因治疗,我们比较了八种不同慢病毒假型转导神经元和胶质肿瘤细胞系的效率。在这里,用人泡沫病毒、狂犬病病毒、莫科拉病毒或嗜异性小鼠白血病病毒包膜假型化的慢病毒载体在神经母细胞瘤中显示出最高的转导效率,而用来自阿姆斯特朗53b株的淋巴细胞性脉络丛脑膜炎病毒糖蛋白进行假型化在胶质瘤中产生了最高的转导效率。
