 AB    The hypervariable region 3 (V3) within the disulfide-bridged loop of the
       envelope protein of the human immunodeficiency virus type 1 (HIV-1)
       contains an amino acid sequence that was defined as a principal
       neutralizing determinant (PND). A 19-amino acid residue consensus
       sequence (designated V3C) predicted from the PND sequences of 245
       isolates as well as a sequence from the PND of the WMJ2 HIV-1 isolate
       (designated V3M) were expressed on the variable region of murine-human
       immunoglobulin (Ig) chimeras that were designated Ig-V3C and Ig-V3M,
       respectively. The HIV-1 sequences on the Ig chimeras preserved their
       antigenicity and interacted with antibodies specific for peptides
       encompassing the V3C and V3M sequences. In baboons, Ig-V3C and Ig-V3M
       induced antibodies that bound V3C and V3M peptides as well as the
       glycoprotein gp120 envelope protein of HIV-1 MN isolate. In addition,
       the baboons' antisera were able to prevent infection of CD4 SupT1
       susceptible T cells by HIV-1 MN. Finally, Ig-V3M chimeras were able to
       stimulate in vitro production of antibodies specific for the HIV-1
       envelope-derived peptides by lymphocytes from HIV-1-infected human
       subjects.
