摘要: 目的:探讨IL-18基因过表达的T细胞对胰腺癌细胞系SW1990的杀伤作用。方法:用PCR技术构建含IL-18基因的重组慢病毒,HEK293T细胞包装后感染分离培养的人T淋巴细胞,与胰腺癌细胞SW-1990共培养后,检测培养上清中的LDH含量、ELISA检测IL-2和IFN-γ的含量,以间接评估其对SW-1990细胞体外的杀伤作用。结果:成功构建和包装了人IL-18的重组慢病毒,感染人T淋巴细胞后,在与人胰腺癌细胞SW-1990共培养条件下,与空白对照组相比,LDH的释放显著增多(P < 0.01);IL-2和IFN-γ的分泌亦显著增多(P < 0.01)。结论:过表达人IL-18蛋白的T淋巴细胞对胰腺癌细胞SW-1990具有更强的杀伤作用。

Abstract: Objective Investigated the antitumor effects of IL-18 gene transfected T cells on pancreatic cancer SW-1990. Methods: Construction of IL-18 contained recombinant lentivirus using PCR method and packaged at HEK293T cell, then transfected the T cells and evaluated the antitumor effects when cocultured with SW-1990. Results the IL-18 gene contained recombinant lentivirus was successfully constructed and packaged, and could transfected the T cells, the LDH secretion and IL-2 and IFN-γ content were all increased significantly (P < 0.01) when cocultured with SW-1990 cell. Conclusions T cells transfected with IL-18 possessed more potent antitumor effects to pancreatic cancer SW-1990 as compared to the regular T cells.
