COMBINATION ANTI-HIV VECTORS, TARGETING VECTORS, AND METHODS OF USE

摘要

Recombinant lentiviral vectors containing at least: a lentiviral backbone comprising essential lentiviral sequences for integration into a target cell genome; a nucleic acid encoding a CCR5 RNAi; and an expression control element that regulates expression of the nucleic acid encoding the CCR5 RNAi element, are provided by this invention. In an alternative aspect, the vector also contains polynucleotides encoding TRIM5 alpha and HIV TAR decoy sequences along with gene expression regulation elements such as promoters operatively linked to the polynucleotides. The vectors are combined with packaging plasmid and envelope plasmids and optionally conjugated to cell-specific targeting antibodies. Diagnostic and therapeutic methods for using the compositions are further provided herein.
