 AB    One strategy for somatic gene therapy for human immunodeficiency virus
       type 1 (HIV-1) infection is based on the regulated expression of
       dominant negative mutants of the HIV-1 gag gene. To limit expression of
       the mutant Gag polypeptide to HIV-1-infected cells, we have constructed
       a replication-defective retroviral vector that contains a Rev-responsive
       element. By using this construct we have obviated problems that can be
       associated with constitutive expression of an exogenous gene, an
       important step toward developing a human therapy. In uncloned T
       lymphocytes infected (transduced) with this retroviral construct, HIV-1
       replication was inhibited by 94% with a concomitant decrease in the
       cytopathic effects of the virus. In addition, simian immunodeficiency
       virus (SIV) replication was also shown to be significantly inhibited,
       suggesting that this mutant Gag protein may have antiviral efficacy
       against a broad range of primate lentiviruses and that an SIV/macaque
       model can be used for further in vivo studies. These results have
       important implications in assessing the potential of somatic gene
       therapy in the treatment of HIV-1 infection.
