Abstract
Neutralization of human immunodeficiency virus type 1 (HIV-1) infection with soluble CD4 (sCD4) can be achieved over a broad range of concentrations for different virus strains. Laboratory virus strains passaged in transformed T-cell lines are typically sensitive to sCD4 neutralization, whereas primary virus isolates require over 100-fold-higher sCD4 concentrations. Using recombinant viruses generated from a laboratory strain, HIV-1NL4-3, and a primary macrophagetropic strain, HIV-1JR-FL, we mapped a region of gp120 important for determining sensitivity to sCD4 neutralization. This same region has previously been defined as important for macrophage and transformed T-cell line tropism and includes the V3 neutralization domain but does not include regions of gp120 that have been shown to be most important for CD4 binding.
