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.
该论文描述了基于TBI的重组蛋白TBI-2F5和TBI-2G12的构建,它们分别包含被广泛中和抗体2F5和2G12识别的HIV-1表位的肽模拟表位。评估了免疫原诱导中和抗体的能力。用重组蛋白TBI、TBI-2F5和TBI-2G12免疫的BALB/c小鼠血清可中和HIV-1 env假病毒。此外,用TBI-2F5和TBI-2G12免疫的小鼠的混合血清比单个血清更有效地中和HIV-1 B亚型的env假病毒。
