开发用于产生基于HVT的重组疫苗的快速管道。NHEJ修复途径使外源基因的靶向插入更有效。RFP盒的掺入使得重组病毒的鉴定变得容易。重组病毒具有与具有稳定插入物的亲本病毒相似的生长速率。40多年来,火鸡疱疹病毒(HVT)单独或与其他血清型联合使用,已在全球范围内成功用作马立克氏病(MD)的活疫苗。HVT还被广泛用作载体平台,用于使用常规重组方法或重组工程工具在克隆的病毒基因组上产生针对多种禽类疾病如传染性法氏囊病(IBD)、纽卡斯尔病(ND)和禽流感(AI)的重组疫苗。在本研究中,我们描述了基于CRISPR/Cas9的基因组编辑作为产生表达IBDV VP 2蛋白的HVT重组体的快速有效方法的应用。这种方法提供了一种将其他病毒抗原引入HVT基因组的有效方法,用于重组疫苗的快速开发。
Development of a rapid pipeline for generating recombinant HVT-based vaccines. NHEJ repair pathway makes targeted insertion of the foreign gene more efficient. Incorporation of RFP cassette enables the easy identification of recombinant virus. The recombinant virus has similar growth rate as parental virus with stable inserts. Herpesvirus of turkeys (HVT) has been successfully used as live vaccine against Marek's disease (MD) worldwide for more than 40 years either alone or in combination with other serotypes. HVT is also widely used as a vector platform for generation of recombinant vaccines against a number of avian diseases such as infectious bursal disease (IBD), Newcastle disease (ND) and avian influenza (AI) using conventional recombination methods or recombineering tools on cloned viral genomes. In the present study, we describe the application of CRISPR/Cas9-based genome editing as a rapid and efficient method of generating HVT recombinants expressing VP2 protein of IBDV. This approach offers an efficient method to introduce other viral antigens into the HVT genome for rapid development of recombinant vaccines.
