A Moloney murine leukemia virus-based retroviral vector pseudotyped by the insect retroviral gypsy envelope can infect Drosophila cells.


ABSTRACT: The gypsy element of Drosophila melanogaster is the first retrovirus identified so far in invertebrates. Previous data suggest that gypsy ENV-like ORF3 mediates viral infectivity. We have produced in the 293GP/LNhsp701ucL.3 human cell line a Moloney murine leukemia virus-based retroviral vector pseudotyped by the gypsy ENV-like protein. We have shown by immunostaining that the gypsy envelope protein is produced in 293GP/LNhsp701ucL.3 cells and that vector particles collected from these cells can infect Drosophila cells. Our results provide direct evidence that the infectious property of gypsy is due to its ORF3 gene product.
