A functional measles virus replication and transcription machinery encoded by the vaccinia virus genome.

Measles virus encodes three proteins required for the encapsidation, transcription and replication of viral genomes. The genes for these proteins have been inserted into the vaccinia virus genome together with the gene for the bacteriophage T7 RNA polymerase. Cells infected with this recombinant virus were able to encapsidate, transcribe and replicate a CAT gene positioned in the negative polarity behind a T7 promoter and flanked by measles virus genomic termini. Inhibition of the accumulation of the nucleocapsid proteins by actinomycin D led to an increase in CAT expression. Thus the measles virus polymerase activity, encoded by the vaccinia genome, was regulated by the level of measles proteins just as the authentic polymerase. The recombinant vaccinia described in this study could be useful for the production of measles virus-like particles encoding foreign genes and employed in vaccination or gene therapy strategies.[1]
