目的:构建携带人白细胞介素-10(hIL-10)基因的腺病毒载体,并验证其对大鼠肝细胞损伤的保护作用。方法:以pORF-hIL-10质粒为模板, PCR 扩增 hIL-10,插入腺病毒质粒 pDC315,构建 pDC315-hIL-10。将pDC315-hIL-10质粒与腺病毒包装质粒共转染293细胞,产生复制缺陷型重组腺病毒Ad5-hIL-10;感染大鼠肝细胞,免疫学方法鉴定目的基因的表达;建立CCL4诱导的大鼠肝细胞损伤模型,观察Ad5-hIL-10不同感染强度( MOI)预处理对损伤肝细胞存活率的影响。结果:经PCR扩增,证明已正确构建重组腺病毒Ad5-hIL-10。大鼠肝细胞感染Ad5-hIL-10后,随着病毒MOI的升高,hIL-10表达上升(F=52.667,P<0.001)。不同感染强度( MOI=1、5、10和50) Ad5-hIL-10预处理组大鼠肝细胞存活率较损伤对照组升高,差异有统计学意义(F=23.645、22.533、30.697、35.559,P均<0.001)。结论:成功构建了重组腺病毒 Ad5-hIL-10,其能提高肝细胞的存活能力,对肝细胞有保护作用。

Aim:To construct the adenovirus vector carrying human interleukin-10 (hIL-10) gene, and then identify the expression of hIL-10 and detect its protection effects on rat hepatocytes during liver injury .Methods:The hIL-10 gene was amplified by PCR from template plasmid pORF-hIL-10, then digested with endonuclease and inserted into pDC 315 to construct pDC315-hIL-10.The plasmid pDC315-hIL-10 and the adenovirus vector were cotransfected to 293 cells togenerate the replication-deficient recombinant adenovirus Ad 5-hIL-10.Ad5-hIL-10 was used to infect rat hepatocytes and the expres-sion of hIL-10 was identified by immunology method .Rat hepatocyte injury model was constructed , and the protection effects of Ad5-hIL-10 was investigated in rat model at different multiplicities of infection (MOI).Results: The recombi-nant adenovirus Ad5-hIL-10 was recombined successfully .Rat hepatocytes expressed hIL-10 after infection of Ad5-hIL-10. The expression level of hIL-10 was increased along with the increase of MOI (F=52.667,P<0.001).Cell viability of rat hepatocytes in Ad5-hIL-10-treated group(MOI=1,5,10 and 50) was higher than that in the control group ,the difference has a statistical significance(F=23.645,22.533,30.697,35.559,P<0.001).Conclusion:The recombinant adenovirus Ad5-hIL-10 has been successfully constructed , which could improve hepatocytes viability and protect hepatocytes .
