摘要:

目的:研究印记基因PEG10修饰的树突状细胞(DC)疫苗对肝癌细胞的杀伤效应,为肝癌的治疗提供新的策略。方法:将重组PEG10腺病毒rAd-PEG10感染HLA-A2阳性的人外周血来源的DC,制备PEG10基因修饰的DC疫苗,并在体外刺激HLA-A2阳性限制性的单个核细胞,酶联免疫斑点试验(Enzyme Linked Immunospot Assay, ELISPOT)和标准51Cr释放试验分别检测PEG10腺病毒感染的DC所诱导的特异性CTL活性,并检测对HLA-A2阳性的HepG2肝癌细胞的杀伤作用。结果:成功制备了PEG10基因修饰的树突状细胞(DC)疫苗,并在体外能有效诱导抗原特异性CTL效应,对HepG2肝癌细胞有明显的杀伤毒性。结论:PEG10基因修饰的树突状细胞能有效激发出特异性CTL应答,并对HepG2肝癌细胞有明显的杀伤毒性,为肝癌治疗提供了新思路。

Abstract:

Objective:To explore the effect of dendritic cell modified by PEG10 gene for liver cancer. Methods:Dendritic cells originated from the HLA-A2+ PBMCs were transfected with recombinant adenovirus containing PEG10 full length cDNA, and the modified DC were utilized to generate specific cytotoxicity T lymphocytes (CTL). The activity was analyzed by standard 51Cr releasing assay and ELISPOT. Results:The transfected DCs could elicit specific CTLs, which could secrete IFN-γ and lyse liver tumor cells. Conclusions:The PEG10 recombinant adenovirus transfected DCs may provide a new therapeutic strategy for hepatocellular carcinoma.

Key words: PEG10    Dendritic cell    Hepatocellular carcinoma    Imprinted gene
