CD25 PRE-SELECTIVE COMBINATION ANTI-HIV VECTORS, TARGETING VECTORS, AND METHODS OF USE

摘要

Recombinant vectors containing at least: a backbone comprising essential sequences for integration into a target cell genome; a nucleic acid encoding a CCR5 RNAi operatively linked to a a first expression control element that regulates expression of the nucleic acid encoding the RNAi of the CCR5; a nucleic acid encoding at least the extracellular domain of CD25 operatively linked to a second expression control element that regulates expression of the nucleic acid encoding at least the extracellular domain of CD25 are provided by this disclosure. In an alternative aspect, the vector also contains polynucleotides encoding TRIM5alpha 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.

1. A vector comprising:
(a) a backbone comprising essential sequences for integration into a target cell genome; (b) a nucleic acid encoding a CCR5 RNAi; (c) a first expression control element that regulates expression of the nucleic acid encoding the RNAi of element (b); (d) a nucleic acid encoding at least the extracellular domain of CD25; and (e) a second expression control element that regulates expression of the nucleic acid encoding at least the extracellular domain of CD25.
