AB We describe a novel reporter molecule, the murine surface antigen Thy-1,
useful for immunoselection and detection of retrovirus-mediated
transduction by flow cytometry. A cDNA encoding the murine thy-1 gene
was isolated, and cell surface expression of its gene product was
demonstrated. The Thy-1 glycoprotein was tested as a cell surface
reporter molecule in the context of replication-defective and -competent
retroviruses. Cells transduced via murine retroviral vectors carrying
the thy-1 and the neomycin phosphotransferase genes express Thy-1
glycoprotein on their surfaces. The Thy-1 marker is potentially useful
in gene transfer protocols because selection of transduced cells can be
achieved by immunoselection with anti-Thy-1 antibodies shortly after
infection with the retroviral vector. In addition, a human
immunodeficiency virus type 1 (HIV-1) recombinant expressing Thy-1 is
described, which is replication-competent and syncytium-inducing in
human peripheral blood mononuclear cells (PBMCs) and immortalized
CD4-positive cell lines. Cells infected with this HIV-1 recombinant
express Thy-1 on their surfaces and can be detected and purified by
fluorescence-activated cell sorting (FACS). Because of these properties,
retroviruses expressing this genetic marker can be useful for studies in
gene therapy and of the retroviral life-cycle.
