Characterization of Cells of the Myeloid-Monocytic Lineage (ML-1, HL-60, THP-1, U-937) Chronically Infected with the Human Immunodeficiency Virus-1

The myeloid-monocytic cells ML-1, HL-60, THP-1 and U-937 were chronically infected (for more than 2 years) with the lymphotropic HIV-1 strain HTLV-IIIB. Reinfection experiments revealed that viruses o
