    • This invention provides recombinant entomopoxvirus as a novel vector and method of using such vector for delivery and expression of genes of biological significance to vertebrate cells, including human cells. This invention includes the use of an early entomopoxvirus or like gene promoter to drive the expression of an heterologous gene product in a vertebrate cell infected with the recombinant entomopoxvirus vector. We have discovered that, while the entomopoxvirus vector of this invention does not replicate in the vertebrate cell, it enters vertebrate cell cytoplasm and achieves expression of an heterologous gene inserted into the rEPV without causing cytopathic or cytotoxic effects. We further provide a method for expression of the heterologous gene under control of late, strong entomopoxvirus gene promoters, vertebrate gene or viral promoters, and for stable integration of the heterologous gene delivered by the rEPV into the vertebrate cell.
    • 本发明提供了重组昆虫痘病毒作为新的载体和使用这种载体递送和表达对包括人细胞在内的脊椎动物细胞具有生物学意义的基因的基因的方法。 本发明包括使用早期昆虫病毒或类似基因启动子来驱动感染重组昆虫病毒载体的脊椎动物细胞中异源基因产物的表达。 我们已经发现,虽然本发明的昆虫病毒载体在脊椎动物细胞中不复制,但是它进入脊椎动物细胞质,并且实现插入到rEPV中的异源基因的表达,而不引起细胞病变或细胞毒性作用。 我们进一步提供了一种在晚期,强烈的昆虫痘病毒基因启动子,脊椎动物基因或病毒启动子的控制下表达异源基因的方法,并且将由rEPV递送的异源基因稳定整合到脊椎动物细胞中。
