Patent FR-2644177-A1 (FR)
Title: System for selecting a replication domain of a recombinant poxvirus host
Inventor: PAOLETTI ENZO
IPC: C12N15/39
Filed: 1990-03-08
Abstract: The subject of the invention is a recombinant virus modified in order to express a gene product in a host. The genes which can be replicated in the host have been suppressed from this modified recombinant virus so that the virus manifests a limited replication in the host. The modified recombinant virus also contains DNA which encodes and expresses the gene product in the host even when there is a limited replication of the virus in the host. The modified recombinant virus is used in a process for expressing a gene product in a host or in a cell cultured in vitro and in a vaccine for inducing an immunological response in a host inoculated with the vaccine. The subject of the invention is also a selection system for the cloning and expression of open reading frames in poxviruses, especially in the vaccinia virus. The selection system is based on a poxvirus conditional lethal mutant (domain of replicability in the host). A suppression/recombinant mutant of the vaccinia virus is produced and is capable of forming plaques on fibroblasts of primary chicken embryos and monkey cell lines (BSC-40 or VERO) but is deficient in the replication of the human cell line MRC-5. The insertion of the host-replicable gene into the suppression/recombinant mutant restores the capacity for growth on MRC-5 cells. A series of plasmids are prepared which permit rapid cloning, in a single step, and also the expression of any open reading frame when it is recombined with the suppression/recombinant mutant and screened for culture on MRC-5 cells.
