由于其与循环血液直接接触,内皮细胞为用于基因治疗目的的逆转录病毒载体转导提供了有吸引力的靶标。为了了解有效的基因转移和表达是否可行,用三种莫洛尼鼠白血病病毒衍生的逆转录病毒载体感染兔主动脉内皮细胞。其中两个载体携带编码非分泌产物的基因:N2,仅包含选择标记geneneoR,以及SAX,包含neoR基因和SV40促进的腺苷脱氨酶(ADA)基因。第三个载体 G2N 包含分泌型大鼠生长激素 (rGH) 基因和 SV40 启动的 neoR 基因。所有三种载体的感染均导致各自基因的表达。在 G418 中选择之前和之后,在受感染的内皮细胞群中观察到高水平的人 ADA 表达。在合成血管移植物上生长的感染 G2N 的兔主动脉内皮细胞继续将 rGH 分泌到培养基中。这些研究表明内皮细胞可以作为在体内引入功能性重组基因的载体。
By virtue of its immediate contact with the circulating blood, the endothelium provides an attractive target for retroviral vector transduction for the purpose of gene therapy. To see whether efficient gene transfer and expression was feasible, rabbit aortic endothelial cells were infected with three Moloney murine leukemia virus-derived retroviral vectors. Two of these vectors carry genes encoding products that are not secreted: N2, containing only the selectable marker geneneoR, and SAX, containing both neoRgene and an SV40-promoted adenosine deaminase (ADA) gene. The third vector, G2N, contains a secretory rat growth hormone (rGH) gene and an SV40-promoted neoRgene. Infection with all three vectors resulted in expression of the respective genes. A high level of human ADA expression was observed in infected endothelial cell populations both before and after selection in G418. G2N-infected rabbit aortic endothelial cells that were grown on a synthetic vascular graft continued to secrete rGH into the culture medium. These studies suggest that endothelial cells may serve as vehicles for the introduction in vivo of functioning recombinant genes.
