Abstract

The paper describes construction of TBI-based recombinant proteins TBI-2F5 and TBI-2G12 that contain peptide mimotopes of HIV-1 epitopes recognized by broadly neutralizing antibodies 2F5 and 2G12, respectively. The capacity of the immunogens to induce neutralizing antibodies was evaluated. The sera of BALB/c mice immunized with recombinant proteins TBI, TBI-2F5, and TBI-2G12 neutralized HIV-1 env-pseudoviruses. Moreover, pooled serum from mice immunized with TBI-2F5 and TBI-2G12 neutralized env-pseudoviruses of HIV-1 subtype B more effectively than individual sera.
