AB The cell-to-cell transmission of human immunodeficiency virus type 1
(HIV-1) was studied using MOLT-4 cells chronically infected with a
variant strain of HIV-1SF-2 (MOLT-4/HIV-1SF-2H) and CD4+ human lymphoid
MT-4 cells. MOLT-4/HIV-1SF-2H cells produced less than 1 TCID50
infectious particles per day as determined by the cytopathogenicity in
MT-4 cells. However, the expression of envelope glycoproteins gp120 and
gp41 on the MOLT-4/HIV-1SF-2H cell membrane was satisfactory for
syncytium formation with the uninfected MOLT-4 cells. When
MOLT-4/HIV-1SF-2H and MT-4 cells were co-cultured, severe
cytopathogenicity was observed in MT-4 cells without being accompanied
by the formation of multi-nucleated cells. Thus, the system consisting
of MOLT-4/HIV-1SF-2H and MT-4 cells is convenient for exclusive study of
the mechanism of cell-to-cell transmission of HIV-1. Using various
compounds, it was confirmed that cell-to-cell transmission required both
gp120/gp41-CD4 binding and de novo DNA synthesis.
