Title: Potent and broad HIV-neutralizing antibodies in memory B cells and plasma

Abstract

Induction of broadly neutralizing antibodies (bnAbs) is a goal of HIV-1 vaccine development. Antibody 10E8, reactive with the distal portion of the membrane-proximal external region (MPER) of HIV-1 gp41, is broadly neutralizing. However, the ontogeny of distal MPER antibodies and the relationship of memory B cell to plasma bnAbs are poorly understood. HIV-1–specific memory B cell flow sorting and proteomic identification of anti-MPER plasma antibodies from an HIV-1–infected individual were used to isolate broadly neutralizing distal MPER bnAbs of the same B cell clonal lineage. Structural analysis demonstrated that antibodies from memory B cells and plasma recognized the envelope gp41 bnAb epitope in a distinct orientation compared with other distal MPER bnAbs. The unmutated common ancestor of this distal MPER bnAb was autoreactive, suggesting lineage immune tolerance control. Construction of chimeric antibodies of memory B cell and plasma antibodies yielded a bnAb that potently neutralized most HIV-1 strains. external region (MPER) have extensive neutralization breadth, and one of these, 10E8, reactive to the distal MPER, is one of the most broadly reactive HIV-1–neutralizing antibodies isolated to date (1–3). Two other MPER-binding gp41 bnAbs, 2F5 and 4E10, are both polyreactive, and their expression is limited by immune tolerance control in bnAbmore » knock-in mice (4–7). In contrast, the 10E8 bnAb, in addition to potency and breadth, has lower reactivity with host molecules than 2F5 and 4E10 (1, 8–10). Thus, vaccine strategies for induction of 10E8-like antibodies are key to the development of an HIV-1 vaccine that can induce multiple broad and potent neutralizing antibody specificities. Here, we have isolated a clonal lineage (DH511) of broad and potent Env gp41 distal MPER bnAbs from both memory B cells and plasma from an HIV-1–infected African individual, defined the DH511 developmental pathway, and demonstrated the reactivity of the DH511 unmutated common ancestor (UCA) with the A subunit of the autoantigen ribonucleoprotein (RNP), providing a mechanism of bnAb induction. Finally, plasma DH511 bnAb lineage members were equally as potent neutralizers of HIV-1 as were bnAbs derived from memory B cells. Moreover, a chimeric DH511 lineage antibody consisting of memory bnAb V H [variable region of immunoglobulin (Ig) heavy chain] and plasma bnAb V L (variable region of Ig light chain) was broader than 10E8 and neutralized 99% of the HIV-1 isolates tested.« less
