title: Characterization of human immunodeficiency virus-1-infected cells of myeloid-monocytic lineage (ML-1, HL-60, THP-1, U-937).
abstract: The myeloid-monocytic cells ML-1, HL-60, THP-1, and U-937 were chronically infected (for > 2 years) with the lymphotropic human immunodeficiency virus type 1 (HIV-1) strain HTLV-IIIB. Reinfection experiments revealed that viruses obtained from chronically infected ML-1/HIV-1 and HL-60/HIV-1 cells showed a low infectivity if tested with uninfected ML-1 and HL-60 cells in contrast to virus preparations from chronically infected THP-1/HIV-1 and U-937/HIV-1 with their corresponding uninfected cell lines. Analyses of selected cell surface markers revealed a differential expression of CD4, CD8, CD11c, CD14, CD15, CD20, HLA-DR, and HLA-DQ in non- or chronically infected cells. In chronically infected cells, the steady-state levels for tumor necrosis factor-alpha, interleukin (IL)-1 beta, and granulocyte-macrophage colony-stimulating factor mRNA remained unchanged whereas the one for IL-6 dropped.
