In an effort to develop a useful AIDS vaccine or vaccine component,
we have generated a combinatorial library of chimeric viruses in which
the sequence IGPGRAFYTTKN from the V3 loop of the MN strain
of human immunodeficiency virus type 1 (HIV-1) is displayed in many
conformations on the surface of human rhinovirus 14 (HRV14). The V3
loop sequence was inserted into a naturally immunogenic site of the
cold-causing HRV14, bridged by linkers consisting of zero to three
randomized amino acids on each side. The library of chimeric viruses
obtained was subjected to a variety of immunoselection schemes to
isolate viruses that provided the most useful presentations of the V3
loop sequence for potential use in a vaccine against HIV. The utility
of the presentations was assessed by measures of antigenicity and
immunogenicity. Most of the immunoselected chimeras examined
were potently neutralized by each of the four different monoclonal
anti-V3 loop antibodies tested. Seven of eight chimeric viruses were
able to elicit neutralizing antibody responses in guinea pigs against
the MN and ALA-1 strains of HIV-1. Three of the chimeras elicited HIV
neutralization titers that exceeded those of all but a small number of
previously described HIV immunogens. These results indicate that
HRV14:HIV-1 chimeras may serve as useful immunogens for stimulating
immunity against HIV-1. This method can be used to flexibly reconstruct
varied immunogens on the surface of a safe and immunogenic vaccine
vehicle.
