摘    要:目的评估广州地区人群中人腺病毒5型(HAdV-5)中和抗体阳性率情况。方法采用以β-半乳糖苷酶(LacZ)为报告基因,结合CMV启动子的人重组腺病毒5型载体,运用化学发光法,检测209份免疫功能正常的成人血清样本中HAdV-5的中和抗体。结果 HAdV-5中和抗体的阳性率为82.3%(172/209)。HAdV-5中和抗体在〈1:20(低滴度)、1:40-1:160(中滴度)、1:320-1:1280(高滴度)、〉1:1280(超高滴度)时均能检测到,而且随着滴度的增加,阳性率逐渐升高。在20~40岁时HAdV-5中和抗体阳性率最高,在〈20岁时HAdV-5阳性率最低。结论广州地区人群中针对HAdV-5的先存中和抗体阳性率高,应用基于该种DNA病毒作为载体进行基因疫苗及基因治疗的研究时,具有一定的局限性。

关 键 词:人腺病毒5型  化学发光法  中和抗体

Abstract:Objective To estimate the epidemic situation of preexisting neutralizing antibody of human adenovirus type 5(HAdV-5) in Guangzhou population.Methods β-galactosidase(LacZ) as reporter gene,CMV promoter driven recombinant HAdV-5 vector and chemiluminescence method were used to investigate the present of neutralizing antibodies against HAdV-5 in the serum of 209 immunocompetent individuals.Results We found that the positive rate of HAdV-5 neutralizing antibodies was 82.3%(172:209).The HAdV-5 neutralizing antibodies could be detected at low(〈1:20),medium(1:40-1:160),high(1:320-1:1 280) and ultra-high(〉1:1 280) titers.The positive rate of HAdV-5 neutralizing antibodies of the 20-40 year old age group was the highest,while the rate of 〈20 year old age group was the lowest.Conclusion The positive rate of HAdV-5 neutralizing antibodies was high in Guangzhou.So there are some limitations of using this virus vector for gene vaccination and gene therapy research.
Keywords:human adenovirus type 5  chemiluminescence  neutralizing antibody
