AB Using recombinant and mutant viruses generated between two human
immunodeficiency virus type 1 isolates that display differences in cell
tropism and sensitivity to soluble CD4 neutralization, we show that
these two properties of the virus are regulated by different mechanisms.
Whereas there is an association between V3 loop conformation and a
particular cellular tropism, soluble CD4 neutralization sensitivity
appears to be determined by amino acid differences in the C2 domain of
the envelope gp120 that modulate the stability of gp120-gp41
association. Our findings further illustrate the importance of
functional interactions among different regions of the envelope gp120 in
regulating the biological phenotypes of human immunodeficiency virus and
suggest that additional probing of the V3 loop with monoclonal
antibodies may identify specific structural features of this loop that
determine cell tropism.
