DUAL VECTOR FOR INHIBITION OF HUMAN IMMUNODEFICIENCY VIRUS

摘要

The present invention provides an expression vector for preventing or inhibiting HlV entry, fusion or replication in mammalian cells. In particular, the invention provides a recombinant retroviral vector that encodes an inhibitor of a HlV co-receptor, such as CCR5 or CXCR4, and a protein that inhibits HIV fusion to target cells and/or HIV replication. Pharmaceutical compositions comprising such constructs and methods of use thereof to prevent or treat HIV infection in a patient are also disclosed.
