+ T cells in peripheral blood. Because this interaction would confound the selection of B cells expressing CD4bs IgG, we additionally sought to design proteins containing the majority of the CD4bs epitope surface that maintained b12 reactivity but that no longer bound to CD4. Specifically, computer-assisted modeling was used to alter the β20/21 region of gp120 that is required for CD4 binding but is not part of the b12-contact surface (fig. S1).

Additional studies using primary PBMC-derived viral isolates and PBMC as target cells confirmed that VRC01, VRC02, and VRC03 were able to neutralize replication-competent uncloned HIV-1 isolates grown in primary T cells (table S3). We also tested the impact of VRC01 on the functional viral spike because VRC01 and VRC02, like CD4, showed the ability to alter the conformation of gp120 and enhanced binding of CD4-induced antibodies like 17b. Unlike CD4, however, VRC01 did not promote the entry of primary HIV-1 isolates into CD4-negative cells, and it did not augment the neutralization potency of mAb 17b (fig. S7).

Our successful isolation of CD4bs mAbs with extensive neutralization breadth was likely due to several factors. Recent advances in high-throughput neutralization assays facilitated the identification of HIV-1 antisera containing broad NAbs (4-7, 29-32). Advances in serum epitope mapping technologies led us to understand that conserved regions of HIV-1 Env may be targeted by such NAbs (4, 7, 9, 30, 33-37). The atomic-level structure of gp120 (10, 38) and advances in computational modeling allowed development of the RSC probe pair that was used to identify and sort CD4bs antibody-secreting B cells. Because of the large repertoire of circulating antibodies against gp120, most of them nonneutralizing, the epitope selectivity conferred by the RSC3 protein, together with use of the knock-out mutant, was likely important for the identification of the relatively rare memory B cells secreting NAbs to the CD4bs. Recently, the gp140 form of Env was used to identify HIV-1-specific B cells and study the repertoire of the antibody responses to the Env glycoprotein (16). Numerous unique antibodies were derived from each of six HIV-1-infected donors, but no single mAb demonstrated broad and potent neutralization. The ability to identify epitope-specific B cells, and isolate the specific IgG clones, has broad potential application. A similar epitope-specific approach could be used to isolate mAbs to sites of known structure from infectious disease pathogens, including tuberculosis and malaria, and can be applied to the identification of targets of autoimmunity or cancer therapy.

Unlike CD4, VRC01 and VRC02 do not appear to require interaction with the conformationally mobile b20/21 region of gp120, because this region was altered in the RSC3 protein.
