摘    要:目的:将IL-12重组载体转染入小鼠成纤维细胞,研究探讨转染后的抗肿瘤作用.方法:取小鼠胚胎获得原代成纤维细胞,应用PEI法将IL-12重组载体转染到小鼠胚胎成纤维细胞,同时设对照.建立肉瘤细胞(S-180)荷瘤小鼠模型,分别接种S-180细胞.于注射瘤细胞后定期给予转染后的成纤维细胞瘤体内注射,并设对照组.于致瘤后第21日处死小鼠,测肿瘤质量; ELISA法检测小鼠血清IL-12及γ-干扰素(IFN-γ)的表达; 检测NK(natural killer cells)细胞活性和脾淋巴细胞增殖情况、CD4/IFN-γ、CD8/IFN-γ双标记阳性细胞的克隆能力.结果:抑瘤率、NK细胞活性及淋巴细胞增生反应、血清IL-12、IFN-γ水平、CD4/IFN-γ及CD8/IFN-γ双标记阳性细胞的百分率均高于对照组(P〈0.01).结论:转染后的IL-12重组质粒可进一步增强机体的免疫功能发挥其抗肿瘤的治疗作用.

Abstract:AIM:To investigate the anti-tumor effects of mouse embryonic fibroblasts-mediated interleukin-12(IL-12) on Sarcoma 180 xenografts.METHODS:The murine normal fibroblast were transfected with human IL-12 gene(FB/IL-12) by PEI.Controls were set up at the same time.The S-180 cells were inoculated in mice subcutaneously.Then FB/IL-12 was injected in mice in the same place subcutaneously at intervals,and controls were set up.On the 21st day,tumor weight was recorded.The serum levels of IL-12 and the expression of ...
