ABSTRACT:
The present invention provides pseudotyped retroviral vectors and packaging systems and methods of using such vectors for retroviral-mediated gene transfer. In particular, the present invention provides a retroviral packaging system that comprises at least two vectors: a first vector comprising a gag, a pol, or gag and pol genes; and a second vector comprising a functionally modified or heterologous envelope gene, for example, a baculovirus envelope gene.
