COVER Maturation of human antibodies from germline recombinant (gray ribbon structure), along four lineages (orange, yellow, green, and blue), into potent neutralizers of HIV-1. A mature antibody variable domain is shown binding its target, HIV-1 envelope glycoprotein gp120 (red ribbon structure). Deep sequencing and structural bioinformatics of the antibody repertoires of HIV-infected individuals uncover the genetic record for the development of broadly neutralizing HIV-1 immunity.
