AB The immunogenicity of a newly constructed macromolecular multicomponent
peptide vaccine candidate against human immunodeficiency virus type 1
(HIV-1) was compared with that of previously reported vaccine
candidates. This vaccine candidate is composed of a macromolecular
multicomponent peptide complex consisting of three V3 region peptides,
one Gag region peptide, and CD4-binding site peptide and was constructed
using the multiple-antigen peptide and glutaraldehyde methods. Sera from
rabbits immunized with this newly constructed vaccine showed strong
antibody titers against each constituent peptide antigen. Furthermore,
these antibodies exhibited strong neutralizing and antifusion activity
toward HIV-1IIB, HIV-1MN, and fresh isolates from Japanese
HIV-seropositive individuals. These results show that this new vaccine
candidate has the capacity to induce strong, polyvalent immunogenicity
and therefore may prove to be a powerful peptide vaccine against HIV-1
infection.
