  • Patent number: 11993782
    Abstract: Provided is a lentivirus packaging system, which comprises: a transfer plasmid comprising a nucleotide sequence of TAR-reserved-chimeric 5? long terminal repeat (LTR); at least one packaging plasmid comprising a nucleotide sequence encoding TAR RNA binding protein, a nucleotide sequence of rev gene, a nucleotide sequence of gag gene, and a nucleotide sequence of pol gene; and an envelope plasmid. Due to the expression of gene of TAR RNA binding protein by the packaging plasmids, the produced lentivirus has higher virus titer and can improve the transduction rate and the gene delivery efficiency during cell transduction. The present invention further provides a method of improving lentivirus production in a host cell, which comprises using the lentivirus packaging system to transfect the host cell. The present invention further provides a cell transduced by the lentivirus and a method of using the cell for treating cancer.
