AB Two clinical regimens have been proposed for gene therapies of acquired
immunodeficiency syndrome (AIDS): (i) Genetic modification of
differentiated peripheral mononuclear cells ex vivo and (ii) gene
delivery into hematopoietic stem/progenitor cells ex vivo. Various
antiviral strategies targeted at different molecular processes in the
human immunodeficiency virus type 1 (HIV-1) life cycle are currently
being pursued, all with the goal of reducing HIV-1 replication. Until
now, all successful studies have reported inhibition in acutely
HIV-infected cells that had been genetically modified prior to
infection. These promising results do not address a clinically relevant
question: What is the contribution of already infected peripheral
mononuclear and hematopoietic stem/progenitor cells to disease
progression? In this report, we demonstrate inhibition of both HIV-1
replication and production of infectious particles in chronically
infected human T leukemia cell lines. The antiviral effect on the
transduced cell population correlates with the expression of the
dominant-negative RevM10 protein. This is the first demonstration that a
gene therapy-based treatment can achieve antiviral efficacy in human T
leukemia cells chronically infected with HIV-1.
