| 摘 要： | 本研究旨在研发经济、高效的人高致病性禽流感病毒H5N1实验疫苗并优化免疫方案。首先优化并合成H5N1(安徽株)的血凝素基因(HAop)和神经氨酸酶基因(NAop)并证实其正确表达,再构建含有H5N1(安徽株)结构基因的多个单顺反子(HAwt、HAop和NAop)和双顺反子(HAop/M2和NAop/M1)DNA疫苗质粒。随后,采用不同途径的体内电转法在第0周和第3周2次免疫Balb/C小鼠,初步分析了抗原特异性体液免疫(HA血凝抑制抗体,NA特异性抗体,中和抗体)和细胞免疫应答(IFN-γELISpot)的特点。结果表明:含有优化血凝素基因(HAop)和优化神经氨酸酶基因(NAop)的DNA疫苗可以快速激发较强的免疫应答,尤其是细胞免疫应答;皮内电转所激发的体液免疫应答强于肌肉电转。本研究为新型H5N1疫苗的研发以及免疫方案的优化奠定了基础。

| Abstract: | This study aims to develop inexpensive and effective experimental vaccines against highly pathogenic H5N1 Avian Influenza (HPAI) virus and to optimize their immunization programs. To this end,we first synthesized the codon-optimized hemagglutinin gene (HAop) and neuraminidase gene (NAop),both of which were derived from a H5N1 virus (Anhui strain),and constructed successfully the DNA vaccines containing a single cistronic construct (HAwt,HAop,or NAop) or a bicistronic construct (HAop/M2 or NAop/M1) of H5N1 i... |
