In a previous study, an apathogenic strain of bovine herpesvirus 4 (BoHV-4) cloned as a bacterial artificial chromosome and expressing a chimeric peptide (gE2/gD) as a secreted form was described. Recombinant virus-inoculated animals produced antibodies against bovine viral diarrhea virus (BVDV) gE2 and BoHV-1 gD. However, neutralizing antibodies were produced only against BVDV, not against BoHV-1. In the present work a recombinant BoHV-4 expressing a membrane-linked form of gE2/gD chimeric peptide was constructed, and inoculated rabbits produced serum-neutralizing antibodies against both BVDV and BoHV-1. Protein cell sorting and targeting are a very important issue when immunodominant antigens are engineered for recombinant virus vaccine development.
在之前的一项研究中,描述了一种牛疱疹病毒4(BoHV-4)的无致病性菌株,其作为细菌人工染色体进行克隆,并表达一种作为分泌形式的嵌合肽(gE2/gD)。接种重组病毒的动物产生了针对牛病毒性腹泻病毒(BVDV)gE2和BoHV-1 gD的抗体。然而,仅产生了针对BVDV的中和抗体,而未产生针对BoHV-1的中和抗体。在本研究中,构建了一种表达gE2/gD嵌合肽膜连接形式的重组BoHV-4,接种后的兔子产生了针对BVDV和BoHV-1的血清中和抗体。当为重组病毒疫苗开发设计免疫显性抗原时,蛋白质细胞分选和靶向是一个非常重要的问题。
