摘要: 目的:构建人乳头瘤病毒的细胞毒性T淋巴细胞(CTL)表位疫苗并在大肠杆菌中表达。方法:应用多轮PCR 的方法合成CTL表位基因序列,将其亚克隆入pET28a表达载体中,并在大肠杆菌BL21 (DE3) 中表达重组蛋白质,用Western blotting对重组蛋白进行鉴定。结果:采用计算机表位预测的方法选取HPV6、11、16型的CTL表位,通过5轮PCR 人工合成人乳头瘤病毒CTL表位疫苗的基因片段HPVepi,用亚克隆的方法构建了重组表达质粒pET28a-Tat-HPVepi,并在大肠杆菌高效表达了该重组蛋白质,经Western blotting鉴定显示出特异性条带。结论:结合计算机表位预测和PCR的方法构建并在大肠杆菌中高效表达了一种人乳头瘤病毒CTL表位疫苗。

Abstract: To construct a CTL epitope vaccine against human papillomavirus and to express it in E. coli. Methods The gene sequences encoding CTL epitopes selected by computer-assisted epitope prediction were synthesized by PCR and sub-cloned into pET28a expression vector. The recombinant plasmid pET28a-Tat-HPVepi was transformed to E. coli for expression and the expressed protein was identified by Western blotting. Results The DNA sequences of selected CTL epitopes were obtained by 5 rounds of PCR, the constructed recombinant plasmid pET28a-Tat-HPVepi was effectively expressed in E. coli. The expressed products,identified by Western blotting,showed specific bands. Conclusion The CTL epitope vaccine against human papillomavirus is successfully constructed and express in E. coli.
