Abstract: Presented are ways to address the problem of replication competent adenovirus in adenoviral production for use with, for example, gene therapy. Packaging cells having no overlapping sequences with a selected vector are suited for large-scale production of recombinant adenoviruses.

Abstract: Large-scale packaging of alphavirus replicons is accomplished by co-transfecting host cells with three RNA molecules: (1) an alphavirus replicon comprising a sequence encoding a heterologous protein; (2) a helper RNA encoding a capsid protein and (3) a helper RNA encoding two alphavirus glycoproteins. The helper RNAs contain cis-acting elements that allow efficient replication of the helper RNAs and their packaging into viral particles as well as packaging of replicon genomes. These populations of viral particles can be propagated at high titers in cell culture by infecting cells at high multiplicity. Propagation of packaged replicons at an escalating scale is useful for large-scale production of recombinant proteins and/or vaccine.
