Use of a recombinant murine cytomegalovirus expressing vesicular stomatitis virus G protein to pseudotype retroviral vectors.
A new method of producing vesicular stomatitis virus (VSV) G protein pseudotyped retroviral vectors is described. In this method, stocks of VSV-G pseudotyped vector were reproducibly obtained by infecting an env-, human, retroviral vector producer cell line with a recombinant murine cytomegalovirus (CMV) which expresses VSV-G protein. The recombinant murine CMV, RMCMVG, expressed VSV-G protein under transcriptional control of the human CMV immediate-early promoter. RMCMVG, like murine CMV, can infect human cells, but the infection is limited to the expression of the viral immediate-early genes; no productive replication of murine CMV occurs. Recombinant murine CMV vector infection of non-permissive cells may be useful in situations where high levels of gene expression are desired without concomitant viral vector replication.
