AB A strain of human immunodeficiency virus type 1 that is strictly tropic
for primary human blood cell cultures was constructed in vitro.
Mutational studies on the vif, vpr, vpu and nef genes of this virus were
performed to evaluate their biological functions in natural target
cells. For this purpose, replication properties of mutant viruses in
peripheral blood mononuclear cells (PBMCs) and macrophages (PBMPs) were
determined. Three phenotypes with respect to virus replication were
noticed: normal or mildly retarded growth (nef and vpr mutants),
impaired growth (vpu mutant), and no growth (vif mutant). These results
suggest that the Vif and Vpu proteins are more important than the Nef
and Vpr proteins for virus replication in PBMCs and PBMPs.
