| Popis: | The broadly neutralizing HIV-1 antibody b12 recognizes the CD4 binding site of the HIV-1 envelope glycoprotein gp120 and efficiently neutralizes HIV-1 infections in vitro and in vivo. Based on the 3D structure of a b12⋅gp120 complex, we have designed an assembled peptide (b12-M) that presents the parts of the three heavy-chain complementarity-determining regions (CDRs) of b12, which contain the contact sites of the antibody for gp120. This b12-mimetic peptide, as well as a truncated peptide presenting only two of the three heavy-chain CDRs of b12, were shown to recognize gp120 in a similar manner to b12, as well as to inhibit HIV-1 infection, demonstrating functional mimicry of b12 by the paratope mimetic peptides. |
