Modulation of HIV-1 macrophage-tropism among R5 envelopes occurs before detection of neutralizing antibodies
HIV-1 R5 viruses vary widely in their capacity to infect primary macrophages. R5 macrophage-tropism is associated with an increased envelope:CD4 affinity that partly results from an increased exposure of CD4 contact residues on gp120 and allows the use of low levels of CD4 for infection. The selecti...
