| 摘 要： | 为研究兔出血症病毒(RHDV)的复制机制、病毒与宿主之间的相互作用以及致病机制等,创建一个安全、有效的技术平台,在前期构建的RHDV侵染性克隆基础上,将病毒的衣壳蛋白编码区删除,保留了RHDV复制必需的所有蛋白酶基因和两端的非编码区,构建了RHDV复制子。试验结果证明,将该复制子RNA导入RK13细胞中后,能够进行高水平的复制和表达。

| Abstract: | To provide an efficient and safe technology platform for studying the replication and pathogenesis mechanisms of RHDV,the interaction between the RHDV and its host cells,a replicon system of RHDV,was constructed based on the infectious cDNA clone of RHDV,in which VP60 gene encoding the capsid protein was deleted,but all the necessary protease coding regions and non-coding regions were retained.Results from RT-PCR,IFA and qRT-PCR confirmed that the replicon RNA could efficiently replicate in RK-13cells.Besides,the results also suggested that the capsid protein which is the structural protein of RHDV is necessary for maintaining the viral infectivity. |
