VRC03: This study demonstrated that bNAb signatures can be utilized to engineer HIV-1 Env vaccine immunogens eliciting Ab responses with greater neutralization breadth. Data from four large virus panels were used to comprehensively map viral signatures associated with bNAb sensitivity, hypervariable region characteristics, and clade effects. The bNAb signatures defined for the V2 epitope region were then employed to inform immunogen design in a proof-of-concept exploration of signature-based epitope targeted (SET) vaccines. V2 bNAb signature-guided mutations were introduced into Env 459C to create a trivalent vaccine which resulted in increased breadth of NAb responses compared with Env 459C alone. VRC03 was used for analyzing clade sensitivity.

VRC03: The influence of a V2 State 2/3-stabilizing Env mutation, L193A, on ADCC responses mediated by sera from HIV-1-infected individuals was evaluated. Conformations spontaneously sampled by the Env trimer at the surface of infected cells had a significant impact on ADCC. State 1-preferring ligand VRC03 recognized L193A variants of CH58 and CH77 IMCs with less efficiently compared to the WT.

VRC03: This review discusses the identification of super-Abs, where and how such Abs may be best applied and future directions for the field. VRC03 was isolated from human B cell clones and is functionally similar to VRC01. Antigenic region CD4 binding site (Table:1)

VRC03: A panel of bnAbs were studied to assess ongoing adaptation of the HIV-1 species to the humoral immunity of the human population. Resistance to neutralization is increasing over time, but concerns only the external glycoprotein gp120, not the MPER, suggesting a high selective pressure on gp120. Almost all the identified major neutralization epitopes of gp120 are affected by this antigenic drift, suggesting that gp120 as a whole has progressively evolved in less than 3 decades.

VRC03: Assays of poly- and autoreactivity demonstrated that broadly neutralizing NAbs are significantly more poly- and autoreactive than non-neutralizing NAbs. VRC03 is neither autoreactive nor polyreactive.

VRC03: This study describes a computational method to calculate the binding affinities of antibodies and antigens. The method called free-energy perturbation (FEP) was developed using HIV-1 Env gp120 and 3 VRC01-class mAbs, VRC01, VRC03, and VRC-PG04.

VRC03: This study performed cyclical permutation of the V1 loop of JRFL in order to develop better gp120 trimers to elicit neutralizing antibodies. Some mutated trimers showed improved binding to several mAbs, including VRC01, VRC03, VRC-PG04, PGT128, PGT145, PGDM1400, b6, and F105. Guinea pigs immunized with prospective trimers showed improved neutralization of a panel of HIV-1 pseudoviruses.

VRC03: This study investigated the ability of native, membrane-expressed JR-FL Env trimers to elicit NAbs. Rabbits were immunized with virus-like particles (VLPs) expressing trimers (trimer VLP sera) and DNA expressing native Env trimer, followed by a protein boost (DNA trimer sera). N197 glycan- and residue 230- removal conferred sensitivity to Trimer VLP sera and DNA trimer sera respectively, showing for the first time that strain-specific holes in the "glycan fence" can allow the development of tier 2 NAbs to native spikes. All 3 sera neutralized via quaternary epitopes and exploited natural gaps in the glycan defenses of the second conserved region of JR-FL gp120. All the neutralizing rabbit sera showed significant competition with CD4bs mAbs VRC03, VRC07, b12 and 1F7.

VRC03: Env residue N197 on the BG505-SOSIP trimer was mutated to test the effect of its glycosylation on the binding kinetics of CD4BS and other mAbs. Removal of the glycan had little effect on the overall structure of the molecule. Its removal resulted in increased binding of CD4 and CD4BS antibodies (VRC01, VRC03, V3-3074), but little effect on bNAbs targeting other epitopes (PG9, PG16, PGT145, 17b, A32, 2G12, PGT121, PGT126). Two CD4BS-binding antibodies tested (b12, F105) had insufficient breadth to bind the BG505-SOSIP trimer. Removal of the N197 glycan may allow for the development of better SOSIP immunogens, particularly to elicit CD4BS-specific Abs.

VRC03: Somatic hypermutation and affinity maturation improve an antibody's complementarity with its target epitope. Mass spectroscopy and X-ray structures were used to examine two classes of mAbs, CD4 binding Abs (VRC03, VRC-PG04) and V2 binding Abs (VRC26.01, VRC26.03, VRC26.10, PG16, CH03), to determine how specific mutations that occurred during maturation affected the binding of the mAbs to their target epitope.

VRC03: Env trimer BG505 SOSIP.664 as well as the clade B trimer B41 SOSIP.664 were stabilized using a bifunctional aldehyde (glutaraldehye, GLA) or a heterobifunctional cross-linker, EDC/NHS with modest effects on antigenicity and barely any on biochemistry or structural morphology. ELISA, DSC and SPR were used to test recognition of the trimers by bNAbs, which was preserved and by weakly NAbs or non-NAbs, which was reduced. Cross-linking partially preserves quaternary morphology so that affinity chromatography by positive selection using quaternary epitope-specific bNAabs, and negative selection using non-NAbs, enriched antigenic characteristics of the trimers. Binding of the anti-CD4bs bNAb VRC03 to trimers was minimally affected by trimer cross-linking.

VRC03: A new trimeric immunogen, BG505 SOSIP.664 gp140, was developed that bound and activated most known neutralizing antibodies but generally did not bind antibodies lacking neuralizing activity. This highly stable immunogen mimics the Env spike of subtype A transmitted/founder (T/F) HIV-1 strain, BG505. Anti-CD4bs bNAb VRC03 neutralized BG505.T332N, the pseudoviral equivalent of the immunogen BG505 SOSIP.664 gp140, and was shown to recognize and bind the immunogen too.

VRC03: This study described a natural interaction between Abs and mucin protein, especially, MUC16 that is enhanced in chronic HIV infection. Agalactosylated (G0) Abs demonstrated the highest binding to MUC16. Binding of Abs to epithelial cells was diminished following MUC16 knockdown, and the MUC16 N-linked glycans were critical for binding.These point to a novel opportunity to enrich Abs at mucosal sites by targeting Abs to MUC16 through changes in Fc glycosylation, potentially blocking viral movement. VRC03 produced in either wild-type or FUT8kd 293T cells to produce fucosylated or afucosylated Abs, respectively, was assayed for MUC16 binding by ELISA.

VRC03: This study examined the neutralization of group N, O, and P primary isolates of HIV-1 by diverse antibodies. Cross-group neutralization was observed only with the bNAbs targeting the N160 glycan-V1/V2 site. Four group O isolates, 1 group N isolate, and the group P isolates were neutralized by PG9 and/or PG16 or PGT145 at low concentrations. None of the non-M primary isolates were neutralized by bNAbs targeting other regions, except 10E8, which weakly neutralized 2 group N isolates, and 35O22 which neutralized 1 group O isolate. Bispecific bNAbs (PG9-iMab and PG16-iMab) very efficiently neutralized all non-M isolates with IC50 below 1 ug/mL, except for 2 group O strains. Anti-CD4bs bNAb VRC03 was unable to neutralize any of the 16 tested non-M primary isolates at an IC50< 10µg/ml.

VRC03: The rate of maturation and extent of diversity for the VRC01 lineage were characterized through longitudinal sampling of peripheral B cell transcripts from donor 45 over 15 years and co-crystal structures. VRC01-lineage clades underwent continuous evolution, with rates of ˜2 substitutions per 100 nucleotides per year, comparable with HIV-1 evolution. 39 VRC01-lineage Abs segregated into three major clades, and all Abs from donor 45 contained a cysteine at position 98 (99 in some sequences due to a 1-aa insertion) which was used as a signature to assess membership in the VRC01 lineage. Of 1,041 curated NGS sequences assigned to the VRC01 lineage, six did not contain the cysteine while 1,035 did (99.4%). For this Ab CDR H3 length is 14 and VH changes 30%, Vk nucleotide change is 20%.

VRC03: The human Ab gene repertoires of uninfected and HIV-1-infected individuals were studied at genomic DNA (gDNA) and cDNA levels to determine the frequencies of putative germline Ab genes of known HIV-1 bnAbs. All libraries were deep sequenced and analysed using IMGT/HighV-QUEST software (http://imgt.org/HighV-QUEST/index. The human gDNA Ab libraries were more diverse in heavy and light chain V-gene lineage usage than the cDNA libraries. This implied that the human gDNA Ab gene repertoires may have more potential than the cDNA repertoires to develop HIV-1 bnmAbs. Relatively high frequencies of the VH and VKs and VLs that used the same V-genes and had the same CDR3 lengths as known HIV-1 bnmAbs regardless of (D)J-gene usage. The putative germline genes were determined for a set of mAbs (b12, VRC01, VRC03, NIH45-46, 3BNC60, PG9, PGT127, and X5).

VRC03: The effect of PNGS on viral infectivity and antibody neutralization (2F5, 4E10, b12, VRC01, VRC03, PG9, PG16, 3869) was evaluated through systemic mutations of each PNGS on CRF07_BC strain. Mutations at N197 (C2), N301 (V3), N442 (C4), and N625 (gp41) rendered the virus more susceptible to neutralization by MAbs that recognize the CD4 binding site or gp41. Generally, mutations on V4/V5 loops, C2/C3/C4 regions, and gp41 reduced the neutralization sensitivity to PG16. However, mutation of N289 (C2) made the virus more sensitive to both PG9 and PG16. Mutations at N142 (V1), N355 (C3) and N463 (V5) conferred resistance to neutralization by anti-gp41 MAbs. Available structural information of HIV Env and homology modeling was used to provide a structural basis for the observed biological effects of these mutations.

VRC03: The ability of bNAbs to inhibit the HIV cell entry was tested for b12, VRC01,VRC03, PG9, PG16, PGT121, 2F5, 10E8, 2G12. Among them, PGT121, VRC01, and VRC03 potently inhibited HIV entry into CD4+ T cells of infected individuals whose viremia was suppressed by ART.

VRC03: Cross-group neutralization of HIV-1 isolates from groups M, N, O, and P was tested with diverse patient sera and bNAbs PG9, PG16, 4E10, b12, 2F5, 2G12, VRC01, VRC03, and HJ16. The primary isolates displayed a wide spectrum of sensitivity to neutralization by the human sera, with some cross-group neutralization clearly observed. Among the bNAbs, only PG9 and PG16 showed any cross-group neutralization. The group N prototype strain YBF30 was highly sensitive to neutralization by PG9, and the interaction between their key residues was confirmed by molecular modeling. The conservation of the PG9/PG16 epitope within groups M and N suggests its relevance as a vaccine immunogen.

VRC03: VCRC03 was one of 10 MAbs used to study chronic vs. consensus vs. transmitted/founder (T/F) gp41 Envs for immunogenicity. Consensus Envs were the most potent eliciters of response but could only neutralize tier 1 and some tier 2 viruses. T/F Envs elicited the greatest breadth of NAb response; and chronic Envs elicited the lowest level and narrowest response. This CD4BS binding Nab bound well at <10 nM to 1/5 chronic Envs, 0/6 Consensus Envs and 3/7 T/F Envs. It was the only antibody unable to bind Consensus-S gp140 Env.

VRC03: A highly conserved mechanism of exposure of ADCC epitopes on Env is reported, showing that binding of Env and CD4 within the same HIV-1 infected cell effectively exposes these epitopes. The mechanism might explain the evolutionary advantage of downregulation of cell surface CD4v by the Vpu and Nef proteins. VRC03 was used in CD4 coexpression and competitive binding assay.

VRC03d45: The ontogeny of VRC01 class Abs was determined by enumerating VRC01-class characteristics in many donors by next-gen sequencing and X-ray crystallography. Analysis included VRC01 (donor NIH 45), VRC-PG04 (donor IAVI 74), VRC-CH31 (donor 0219), 3BNC117 (donor RU3), 12A21 (donor IAVI 57), and somatically related VRC-PG19,19b, 20, 20b MAbs from donor IAVI 23. Despite the sequence differences of VRC01-class Abs, exceeding 50%, Ab-gp120 cocrystal structures showed VRC01-class recognition to be remarkably similar.

VRC03: Next generation sequencing was applied to a new donor C38 (different from donor NIH45) to identify VRC01 class bNAbs. VRC01 class heavy chains were selected through a cross-donor phylogenetic analysis. VRC01 class light chains were identified through a five-amino-acid sequence motif. (CDR L3 length of 5 amino acids and Q or E at position 96 (Kabat numbering) or position 4 within the CDR L3 sequence.) VRC03 was used to compare the heavy & light chain sequences as a template of VRC01 class Ab.

VRC03: N276D was determined as the critical binding site of MAb HJ16 by resistance induction in a sensitive primary CRF02_AG strain. N-linked glycosylation site removing N276D mutation was responsible for resistance to HJ16 by site-directed mutagenesis in envs of the homologous CRF02_AG, as well as of a subtype A and a subtype C primary isolate. Sensitivity to the CD4bs VRC01 and VRC03 mAbs was increased in the N276D mutated viruses.

VRC03: A computational method to predict Ab epitopes at the residue level, based on structure and neutralization panels of diverse viral strains has been described.

VRC03: "Neutralization fingerprints" for 30 neutralizing antibodies were determined using a panel of 34 diverse HIV-1 strains. 10 antibody clusters were defined: VRC01-like, PG9-like, PGT128-like, 2F5-like, 10E8-like and separate clusters for b12, CD4, 2G12, HJ16, 8ANC195. This mAb belongs to VRC01-like cluster.

VRC03: Cryoelectron tomography was used to determine structures of A12, m36, or m36/CD4 complexed to trimeric Env displayed on intact HIV-1 BaL virus. The steric interactions at the distal ends of the bound Ab moieties are likely to play a role in determining the rotation of gp120 as in A12 and b12 or without any quaternary structure change as in VRC03.

VRC03: Isolation of VRC06 and VRC06b MAbs from a slow progressor donor 45 is reported. This is the same donor from whom bnMAbs VRC01, VRC03 and NIH 45-46 were isolated and the new MAbs are clonal variants of VRC03. VRC03 was used as a control to compare neutralizing specificity of VRC06.

VRC03: This is a comment on Tan2012. It is noted that Tran and colleagues used high-resolution 3D cryoelectron tomography to define the conformation of Env when bound to soluble CD4 and to a series of monoclonal antibodies. It was demonstrated that antibodies binding to the CD4 binding site or coreceptor binding site of Env may lead to significantly different conformations of the trimeric Env complex. VRC01 locks the complex in a closed conformation, while binding to soluble CD4 or the monoclonal antibody 17b fixed the trimer in an open conformation.
Wright2012
(review, structure)
-
VRC03: Previous cryo-electron tomographic studies were extended. A more complete picture of the HIV entry process was presented by showing that HIV-1 Env binding to either soluble CD4 (sCD4) or the co-receptor mimic 17b leads to the same structural opening, or activation, of the Env spike. Atudy also demonstrated structurally that the broadly neutralizing antibodies VRC01, VRC02, VRC03 are able to block this activation, locking Env in a state that resembles closed, native Env. The cryo-electron microscopic structure of soluble trimeric Env in the 17b-bound state is presented at ˜9 Å resolution, revealing it as a novel, activated intermediate conformation of trimeric Env that could serve as a new template for immunogen design.

VRC03: A computational tool (Antibody Database) identifying Env residues affecting antibody activity was developed. As input, the tool incorporates antibody neutralization data from large published pseudovirus panels, corresponding viral sequence data and available structural information. The model consists of a set of rules that provide an estimated IC50 based on Env sequence data, and important residues are found by minimizing the difference between logarithms of actual and estimated IC50. The program was validated by analysis of MAb 8ANC195, which had unknown specificity. Predicted critical N-glycosylation for 8ANC195 were confirmed in vitro and in humanized mice. The key associated residues for each MAb are summarized in the Table 1 of the paper and also in the Neutralizing Antibody Contexts & Features tool at Los Alamos Immunology Database.

VRC03: Somatic hypermutations are preferably found in CDR loops, which alter the Ab combining sites, but not the overall structure of the variable domain. FWR of CDR are usually resistant to and less tolerant of mutations. This study reports that most bnAbs require somatic mutations in the FWRs which provide flexibility, increasing Ab breadth and potency. To determine the consequence of FWR mutations the framework residues were reverted to the Ab's germline counterpart (FWR-GL) and binding and neutralizing properties were then evaluated. Fig S4C described the comparison of Ab framework amino acid replacement vs. interactive surface area on VRC03.

VRC03: Antigenic properties of 2 biochemically stable and homogeneous gp140 trimers (A clade 92UG037 and C clade CZA97012) were compared with the corresponding gp120 monomers derived from the same percursor sequences. The trimers had nearly all the antigenic properties expected for native viral spikes and were markedly different from monomeric gp120. VRC03 has been discussed as NAb against CD4BS.

VRC03: Polyclonal B cell responses to conserved neutralization epitopes are reported. Cross-reactive plasma samples were identified and evaluated from 308 subjects tested. VRC03 was used as a control mAb in the comprehensive set of assays performed. Plasma sample C1-0219 showed binding and neutralizing activities against native Env trimers similar to VRC03 and b12. D368R mutant trimers completely knocked out VRC03 and b12 but partially reduced C1-0219 binding. C1-0219 was unaffected by the W479G mutant suggesting that its nAbs are more akin to b12 than to VRC03.

VRC03: The rational design of vaccines to elicit broadly neutralizing antibodies to HIV-1 is discussed in relation to understanding of vaccine recognition sites, the structural basis of interaction with HIV-1 env and vaccine developmental pathways. Role of VRC03 has been discussed relating to humoral immune response during HIV1 infection and sites of HIV-1 vulnerability to neutralizing antibodies. VRC03 appears to target the site very effectively resulting in neutralization of ˜90% of circulating isolates.

VRC03: In order to increase recognition of CD4 by Env and to elicit stronger neutralizing antibodies against it, two Env probes were produced and tested - monomeric Env was stabilized by pocket filling mutations in the CD4bs (PF2) and trimeric Env was formed by appending trimerization motifs to soluble gp120/gp14. PF2-containing proteins were better recognized by bNMAb against CD4bs and more rapidly elicited neutralizing antibodies against the CD4bs. Trimeric Env, however, elicited a higher neutralization potency that mapped to the V3 region of gp120.

VRC03: The strategy of incorporating extra glycans onto gp120 was explored, with the goal to occlude the epitopes of non-neutralizing MAbs while maintaining exposure of the b12 site. The focus was on the head-to-head comparison of the ability of 2 adjuvants, monophosphoryl lipid A (MPL) and Quil A, to promote CD4-specific Ab responses in mice immunized with the engineered mutant Q105N compared to gp120wt. Neutralizing and non-neutralizing antibodies targeting three areas on gp120 – the CD4bs (F105, b6, b12, b13, VRC01, VRC03 and CD4- IgG2), the glycosylated ‘silent face’ (2G12) and the V3 loop (B4e8) – were assessed for binding. The antibodies b6, b12, b13, VRC01 and 2G12 bound best to mutant Q105N, albeit with lower affinities than to gp120wt. Retention of b6 and b13 binding was not expected, but can be explained by their very similar mode of interaction with the CD4bs compared to b12. Abs F105 and VRC03 did not bind Q105N at all. The V3-specific antibody B4e8 did not bind to Q105N.

VRC03: VRC01 and VRC03 selection pressures were studied using viral quasispecies from 3 time points (2001, 2006, 2009) in donor 45, from whom VRC01 and VRC03 were initially isolated, and from several time points in 5 additional donors with broadly serum neutralizing Abs. 473 Envs were assessed in total. While most plasma derived autologous Env variants from donor 45 were highly resistant to VRC01, some 2001 Env clones (which are all resistant to VRC01) were sensitive to VRC03 and its clonal relatives VRC06 and VRC06b, suggesting that these mAbs might have evolved at a time point later than VRC01.

VRC03: Broadly neutralizing HIV-1 immunity associated with VRC01-like antibodies was studied by isolation of VRC01-like neutralizers with CD4bs probe; structural definition of gp120 recognition by RSC3-identified antibodies from different donors; functional complementation of heavy and light chains among VRC01-like antibodies; identification of VRC01 antibodies by 454 pyrosequencing; and cross-donor phylogenetic analysis of sequences derived from the same precursor germline gene. VRC03 bound to YU2 gp120 wild type and several mutated proteins, HXB2 gp120 and antigenically resurfaced protein RSC3, but not bound to gp120 YU2 D368R, D368R/I420R and M475S/R476A mutants. gp120-Fab VRC03 complex was crystallized. Heavy- and light-chain cross-pairing chimeras of VRC01, VRC03, VRC-PG04, VRC-CH31 could neutralize up to 90% of 20 clade A, B and C viruses. Thousands of heavy and light chain sequences were found by 454 pyrosequencing, of which 109 sequences, all of IGHV1-2*02 origin, had >90% sequence identity to VRC03, although sequence identity to VRC01 and VRC02 heavy chains was below 75%. Dozens chimeric antibodies obtained by pairing heavy-chain sequences with VRC03 and PG04 light chains and light-chain sequences with VRC01, VRC03,PG04 heavy chains displayed potent neutralization (up to 90%) of A, B and C clade viruses.

VRC03: Two SHIV-C mutants were designed: SHIV-1157ipEL-pΔ3N, a mutant of the early SHIV-1157ipEL-p which lacked the 3N residues in the V2 stem, and SHIV-1157ipd3N4+3N, a mutant of the late SHIV-1157ipd3N4 where 3N residues was added in the V2 stem. VRC03 neutralizes all four SHIV-Cs and avoids the conformational masking by the V2 loop in SHIV-Cs.

VRC03: This broadly neutralizing Ab was derived from B-cells from a donor that were screened for CD4bs mAbs with resurfaced stabilized core 3 (RSC3) protein. The protein was designed to preserve the antigenic structure of the gp120 CD4bs neutralizing surface but eliminate other antigenic regions of HIV-1. VRC03 neutralized 57% of 190 virus strains of different HIV-1 clades. VRC03 bound strongly to RSC3 and was highly somatically mutated. Binding of VRC03 to gp120 was competed by b12 and F105. Unlike for VRC01 and VRC02, binding of 17b was not enhanced by the addition of VRC03.
