Transfer of Human CD4+ T Lymphocytes
Producing Beta Interferon in Hu-PBL-SCID Mice Controls Human
Immunodeficiency Virus Infection

) exerts pleiotropic antiretroviral
activities and affects many different stages of the human
immunodeficiency virus (HIV) infectious cycle in IFN-treated cells. To
explore whether transfer of genetically engineered human
CD4+ T cells producing constitutively low amounts of
IFN-
can eradicate HIV in vivo, we developed a new Hu-PBL-SCID mouse
model supporting a persistent, replicative HIV infection maintained by
periodic reinoculations of activated human CD4+ T cells.
Transferring human CD4+ T cells containing the IFN-
retroviral vector drastically reduced the preexisting HIV infection and
enhanced CD4+ T-cell survival and Th1 cytokine expression.
Furthermore, in 40% of the Hu-PBL-SCID mice engrafted with
IFN-
-transduced CD4+ T cells, HIV-1 was undetectable in
vivo as well as after cocultivation of mouse tissues with human
phytohemagglutinin-stimulated lymphoblasts. These results indicate that
a therapeutic strategy based upon IFN-
transduction of
CD4+ T cells may be an approach to controlling a
preexisting HIV infection and allowing immune restoration.
