摘要
Novel lentivirus packaging systems engineered with a synthetic gene network having a positive feedback loop to amplify the expression of virus genes are provided. When co-transfected into a host cell with a transfer plasmid and envelope vector, extremely high viral titers are achieved when compared to transfection of a host cell with conventional third generation packaging systems. Methods for enhancing production of lentivirus, compositions comprising high titer lentivirus, and therapeutic methods based on delivery of lentiviral nucleic acid to target cells are also provided.
