    • A method for the production of a replication-deficient recombinant virus vector is disclosed. The replication-deficient recombinant virus vector has a recombinant virus genome with one or more defective viral genes. The method comprises infecting a host cell with a carrier virus having a carrier virus genome encoding one or more trans factors or variants thereof, incubating the infected host cell for a desired period of time, and isolating the replication-deficient recombinant virus vector. The carrier virus is a cytoplasmic virus that retains the carrier virus genome in the cytoplasm of the host cell. The host cell contains the recombinant viral genome and retains the recombinant viral genome in a nucleus of the host cell. Also disclosed is a carrier virus for the production of a replication-deficient recombinant virus vector.
    • 公开了一种制备复制缺陷型重组病毒载体的方法。 复制缺陷型重组病毒载体具有带有一个或多个缺陷病毒基因的重组病毒基因组。 该方法包括用载体病毒感染宿主细胞,所述载体病毒具有编码一种或多种反式因子或其变体的载体病毒基因组,将所感染的宿主细胞孵育所需时间,并分离复制缺陷型重组病毒载体。 载体病毒是将载体病毒基因组保留在宿主细胞的细胞质中的细胞质病毒。 宿主细胞含有重组病毒基因组,并将重组病毒基因组保留在宿主细胞的细胞核中。 还公开了用于产生复制缺陷型重组病毒载体的载体病毒。

    • The present invention relates to a method for producing herpes simplex virus (HSV) amplicon particles which includes co-transfecting a host cell with the following: (i) an amplicon vector comprising an HSV origin of replication, an HSV cleavage/packaging signal, and a heterologous transgene expressible in a patient, (ii) one or more vectors individually or collectively encoding all essential HSV genes but excluding all cleavage/packaging signals, and (iii) a vhs expression vector encoding a virion host shutoff protein; and then isolating HSV amplicon particles produced by the host cell, the HSV amplicon particles including the transgene. Also disclosed are a system and a kit for preparing HSV amplicon particles, HSV amplicon particles prepared according to the process of the present invention, and their use.
