    • The present invention provides a composition of matter comprising a defective interfering virus particle, wherein said particle naturally occurs in a human infection and wherein said particles has a naturally occurring core antigen internal deletion. Provided is a pharmaceutical composition, comprising defective interfering virus particle and a pharmaceutically acceptable carrier. Provided is a method for preparing defective interfering virus, comprising the steps of: (1) introduce a defective interfering virus and a complementing plasmid expressing a wild type virus core antigen and optionally containing a drug resistance gene, into a recipient cell; (2) selecting for stably transfected colonies; (3) growing the drug resistant cells and screening for the production of virus DNA replication; and (4) collecting defective interfering virus particles from the medium. Further provided is a vaccine, comprising a defective interfering virus particle.
    • 本发明提供了包含有缺陷的干扰性病毒颗粒的物质组合物,其中所述颗粒天然存在于人感染中,并且其中所述颗粒具有天然存在的核心抗原内部缺失。 提供了一种药物组合物,其包含有缺陷的干扰性病毒颗粒和药学上可接受的载体。 本发明提供一种制备有缺陷的干扰性病毒的方法,其特征在于包括以下步骤:(1)将受损细胞引入缺陷干扰病毒和表达野生型病毒核心抗原的互补质粒,并任选地含有耐药性基因; (2)选择稳定转染的菌落; (3)生长耐药细胞并筛选生产病毒DNA复制; 和(4)从介质中收集有缺陷的干扰性病毒颗粒。 还提供了包含有缺陷的干扰性病毒颗粒的疫苗。
