• PGT126: The Chinese HIV Reference Laboratory produced 124 pseudoviruses from patients with subype B, BC, and CRF01 infections. These viruses were assigned to tiers based on their neutralization by a panel of patient sera. Their neutralization sensitivities were also measured against a panel of well-characterized mAbs (2F5, b12, 2G12, 4E10, 10E8, VRC01, VRC-CH31, CH01, PG9, PG16, PGT121, PGT126). Nie2020 (assay or method development, neutralization)
• PGT126: Chemoenzymatic synthesis, antigenicity, and immunogenicity of the V3 N334 glycopeptides from HIV-1 A244 gp120 have been reported. A synthetic V3 glycopeptide carrying a N334 high-mannose glycan was recognized by bNAb PGT128 and PGT126 but not by 10-1074. Rabbit immunization with the synthetic three-component A244 glycopeptide immunogen elicited substantial glycan-dependent antibodies with broad reactivity to various HIV-1 gp120/gp140 carrying N332 or N334 glycosylation sites. PGT126 could bind all the V3 glycopeptides carrying a high-mannose glycan but not the glycopeptides carrying the complex-type N-glycan. Cai2018 (glycosylation, vaccine antigen design, structure)
• PGT126: 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. PGT126 was used for machine learning regression prediction and to analyze statistical details (Table S4). Bricault2019 (antibody binding site, vaccine antigen design, computational epitope prediction, broad neutralizer)
• PGT126: This review discusses the identification of super-Abs, where and how such Abs may be best applied and future directions for the field. PGT126 was isolated from human B cell clones and is functionally similar to super-Abs PGT121, PGT128 and PGT135. Antigenic region V3 glycan (Table:1). Walker2018 (antibody binding site, review, broad neutralizer)
• PGT126: A systems glycobiology approach was applied to reverse engineer the relationship between bNAb binding and glycan effects on Env proteins. Glycan occupancy was interrogated across every potential N-glycan site in 94 recombinant gp120 antigens. Using a Bayesian machine learning algorithm, bNAb-specific glycan footprints were identified and used to design antigens that selectively alter bNAb antigenicity. The novel synthesized antigens uccessfully bound to target bNAbs with enhanced and selective antigenicity. Yu2018 (glycosylation, vaccine antigen design)
• PGT126: A panel of 14 pseudoviruses of subtype CRF01_AE was developed to assess the neutralization of several neutralizing antibodies (b12, PG9, PG16, 4E10, 10E8, 2F5, PGT121, PGT126, 2G12). Neutralization was assessed in both TZM-bl and A3R5 cell-based assays. Most viruses were more susceptible to mAb-neutralization in A3R5 than in the TZM-bl cell-based assay. The increased neutralization sensitivity observed in the A3R5 assay was not linked to the year of virus transmission or to the stages of infection, but chronic viruses from the years 1990-92 were more sensitive to neutralization than the more current viruses, in both assays. Chenine2018 (assay or method development, neutralization, subtype comparisons)
• PGT126: SOSIP.664 trimer was modified at V3 positions 306 and 308 by Leucine substitution to create hydrophobic interactions with the tryptophan residue at position 316 and the V1V2 domain. These modifications stabilized the resulting SOSIP.v5.2 S306L R308L trimers. In vivo, the induction of V3 non-NAbs was significantly reduced compared with the SOSIP.v5.2 trimers. S306L plus R308L paired substitutions had no effect on the trimer reactivity of PGT126. deTaeye2018 (broad neutralizer)
• PGT126: Three strategies were applied to perturb the structure of Env in order to make the protein more susceptible to neutralization: exposure to cold, Env-activating ligands, and a chaotropic agent. A panel of mAbs (E51, 48d, 17b, 3BNC176, 19b, 447-52D, 39F, b12, b6, PG16, PGT145, PGT126, 35O22, F240, 10E8, 7b2, 2G12) was used to test the neutralization resistance of a panel of subtype B and C pseudoviruses with and without these agents. Both cold and CD4 mimicking agents (CD4Ms) increased the sensitivity of some viruses. The chaotropic agent urea had little effect by itself, but could enhance the effects of cold or CD4Ms. Thus Env destabilizing agents can make Env more susceptible to neutralization and may hold promise as priming vaccine antigens. Johnson2017 (vaccine antigen design)
• PGT126: A panel of mAbs (2G12, VRC01, HJ16, 2F5, 4E10, 35O22, PG9, PGT121, PGT126, 10-1074) was tested to compare their efficacy in cell-free versus cell-cell transmission. Almost all bNAbs (with the exception of anti-CD4 mAb Leu3a) blocked cell-free infection with greater potency than cell-cell infection, and showed greater potency in neutralization of cell-free viruses. The lower effectiveness on neutralization was particularly pronounced for transmitted/founder viruses, and less pronounced for chronic and lab-adapted viruses. The study highlights that the ability of an antibody to inhibit cell-cell transmission may be an important consideration in the development of Abs for prophylaxis. Li2017 (immunoprophylaxis, neutralization)
• PGT126: This review focuses on the potential role of HIV-1-specific NAbs in preventing HIV-1 infection. Several NAbs have provided protection from infection in SHIV challenge studies in primates: b12, VRC01, VRC07-523LS, 3BNC117, PG9, PGT121, PGT126, 10-1074, 2G12, 4E10, 2F5, 10E8. Pegu2017 (immunoprophylaxis, review)
• PGT126: 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. Liang2016 (glycosylation, vaccine antigen design)
• PGT126: Chimeric antigen receptors, i.e., fusion proteins made from single-chain antibodies, may be a useful approach to immunotherapy. A set of mAbs were chosen based on their binding to a variety of sites on Env and availability of antibody sequences. The chimeric receptors were created by fusing the antibody's heavy chain, light chain, and two signaling domains into a single molecule. All 7 antibodies used to make the chimeric receptors (10E8, 3BNC117, PGT126, VRC01, X5, PGT128, PG9) showed specific killing of HIV-1 infected cells and suppression of viral replication against a panel of HIV-1 strains. Ali2016 (immunotherapy, chimeric antibody)
• PGT126: This study assessed the ADCC activity of antibodies of varied binding types, including CD4bs (b6, b12, VRC01, PGV04, 3BNC117), V2 (PG9, PG16), V3 (PGT126, PGT121, 10-1074), oligomannose (2G12), MPER (2F5, 4E10, 10E8), CD4i (17b, X5), C1/C5 (A32, C11), cluster I (240D, F240), and cluster II (98-6, 126-7). ADCC activity was correlated with binding to Env on the surfaces of virus-infected cells. ADCC was correlated with neutralization, but not always for lab-adapted viruses such as HIV-1 NLA-3. PGT126 had moderate to strong ADCC activity against cells infected with 3 of 3 strains tested. vonBredow2016 (ADCC)
• PGT126: HIV-1 bNAb eptiope networks were predicted using 4 algorithms informed by neutralization assays using 282 Env from multiclade viruses. Patch clusters of possible Ab epitope regions were tested for significant sensitivity by site-directed mutagenesis. Epitope (Ab binding site) networks of critical Env residues for 21 bNAb (b12, PG9, PG16, PGT121, PGT122, PGT123, PGT125, PGT126, PGT127, PGT128, PGT130, PGT131, PGT135, PGT136, PGT137, PGT141, PGT142, PGT143, PGT144, PGT145 and PGV04) were delineated and found to be located mostly in variable loops of gp120, particularly in V1/V2. Evans2014 (antibody binding site, computational epitope prediction)
• PGT126: PGT145 was used to positively isolate a subtype B Env trimer immunogen, B41 SOSIP.664-D7324, that exists in two conformations, closed and partially open. bNAbs tested against the trimer were able to neutralize the B41 pseudovirus with a wide range of potencies. All tested non-NAbs did not neutralize B41 (IC₅₀ >50µg/ml). V3 glycan bNAb, PGT121, neutralized the B41 pseudovirus and bound B41 trimer. Pugach2015
• PGT126: A comprehensive antigenic map of the cleaved trimer BG505 SOSIP.664 was made by bNAb cross-competition. Epitope clusters at the CD4bs, quaternary V1/V2 glycan, N332-oligomannose patch and new gp120-gp41 interface and their interactions were delineated. Epitope overlap, proximal steric inhibition, allosteric inhibition or reorientation of glycans were seen in Ab cross-competition. Thus bNAb binding to trimers can affect surfaces beyond their epitopes. PGT126, PGT121, PGT122, PGT123, PGT125 and PGT128, all N332-V3 glycan oligomannose patch bNAbs, were strongly, reciprocally competitive with one another. PGT126 also inhibited binding of CD4bs Ab, CH31 and markedly but incompletely inhibited CD4-IgG2. Derking2015 (antibody interactions, neutralization, binding affinity, structure)
• PGT126: The native-like, engineered trimer BG505 SOSIP.664 induced potent NAbs against conformational epitopes of neutralization-resistant Tier-2 viruses in rabbits and macaques, but induced cross-reactive NAbs against linear V3 epitopes of neutralization-sensitive Tier-1 viruses. A different trimer, B41 SOSIP.664 also induced strong autologous Tier-2 NAb responses in rabbits. Sera from 6/20 BG505 SOSIP.664-D7324 trimer-immunized rabbits were capable of inhibiting VRC01 binding to V3-glycan. 4/4 similarly trimer-immunized macaque sera also inhibited VRC01 binding by >50%. Sanders2015 (antibody generation, neutralization, binding affinity, polyclonal antibodies)
• PGT126: 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-V3 glycan bNAb PGT126, neutralized BG505.T332N, the pseudoviral equivalent of the immunogen BG505 SOSIP.664 gp140, and was shown to recognize and bind the immunogen too. Sanders2013 (assay or method development, neutralization, binding affinity)
• PGT126: Using an escape virus isolated from the PGT125-131 donor, this study found that mutating the V3 core and repositioning critical N-linked glycosylations N295 and N332 could restore virus sensitivity. PGT128 and PGT130 required different sets of changes in order to restore sensitivity, suggesting that this family of bNAbs has two recognition classes (Fig. 2). For example N332 repositioning and 7 amino acid mutations V307I, H308R, E321D, V322I, N325D, P326I, F320H restored PGT128 but not PGT130 virus sensitivity. Krumm2016 (glycosylation, escape)
• PGT126: The IGHV region is central to Ag binding and consists of 48 functional genes. IGHV repertoire of 28 HIV-infected South African women, 13 of whom developed bNAbs, was sequenced. Novel IGHV repertoires were reported, including 85 entirely novel sequences and 38 sequences that matched rearranged sequences in non-IMGT databases. There were no significant differences in germline IGHV repertoires between individuals who do and do not develop bNAbs. IGHV gene usage of multiple well known HIV-1 bNAbs was also analyzed and 14 instances were identified where the novel non-IMGT alleles identified in this study, provided the same or a better match than their currently defined IMGT allele. For PGT126 the published IMGT predicted allele was IGHV4-39*07 and alternate allele predicted from IGHV alleles in 28 South African individuals was IGHV4-39*7m2, with synonymous G298C nucleotide change. Scheepers2015 (antibody lineage)
• PGT126: The study's goal was to produce modified SOSIP trimers that would reduce the exposure - and, by inference, the immunogenicity - of non-NAb epitopes such as V3. The binding of several modified SOSIP trimers was compared among 12 neutralizing (PG9, PG16, PGT145, PGT121, PGT126, 2G12, PGT135, VRC01, CH103, CD4, IgG2, PGT151, 35O22) and 3 non-neutralizing antibodies (14e, 19b, b6). The V3 non-NAbs 447-52D, 39F, 14e, and 19b bound less well to all A316W variant trimers compared to wild-type trimers. Mice and rabbits immunized with modified, stabilized SOSIP trimers developed fewer V3 Ab responses than those immunized with native trimers. deTaeye2015 (antibody binding site)
• PGT126: This study describes a new level of complexity in antibody recognition of the mixed glycan-protein epitopes of the N332 region of HIV gp120. A combination of three antibody families that target the high-mannose patch can lead to 99% neutralization coverage of a large panel of viruses containing the N332/334 glycan site and up to 66% coverage for viruses that lack the N332/334 glycan site. PGT126 was the most effective at neutralizing viruses with the N334 glycan site. Sok2014a (antibody interactions, glycosylation)
• PGT126: Incomplete neutralization may decrease the ability of bnAbs to protect against HIV exposure. In order to determine the extent of non-sigmoidal slopes that plateau at <100% neutralization, a panel of 24 bnMAbs targeting different regions on Env was tested in a quantitative pseudovirus neutralization assay on a panel of 278 viral clones. All bNAbs had some viruses that they neutralized with a plateau <100%, but those targeting the V2 apex and MPER did so more often. All bnMAbs assayed had some viruses for which they had incomplete neutralization and non-sigmoidal neutralization curves. bNAbs were grouped into 3 groups based on their neutralization curves: group 1 antibodies neutralized more than 90% of susceptible viruses to >95% (PGT121-123, PGT125-128, PGT136, PGV04); group 2 was less effective, resulting in neutralization of 60-84% of susceptible viruses to >95% (b12, PGT130-131, PGT135, PGT137, PGT141-143, PGT145, 2G12, PG9); group 3 neutralized only 36-60% of susceptible viruses to >95% (PG16, PGT144, 2F5, 4E10). McCoy2015 (neutralization)
• PGT126: Vectored Immuno Prophylaxis (VIP), involves passive immunization by viral vector-mediated delivery of genes encoding bnAbs for in vivo expression. Robust protection against virus infection was observed in preclinical settings when animals were given VIP to express monoclonal neutralizing Abs. This review article surveyed the status of antibody gene transfer, VIP experiments against HIV and its related virus conduced in humanized mice and macaque monkeys, and discuss the pros and cons of VIP and its opportunities and challenges towards clinical applications to control HIV/AIDS endemics. Yang2014 (immunoprophylaxis, review, antibody gene transfer)
• PGT126: A gp140 trimer mosaic construct (MosM) was produced based on M group sequences. MosM bound to CD4 as well as multiple bNAbs, including VRC01, 3BNC117, PGT121, PGT126, PGT145, PG9 and PG16. The immunogenicity of this construct, both alone and mixed together with a clade C Env protein vaccine, suggest a promising approach for improving NAb responses. Nkolola2014 (vaccine antigen design)
• PGT126: Computational prediction of bNAb epitopes from experimental neutralization activity data is presented. The approach relies on compressed sensing (CS) and mutual information (MI) methodologies and requires the sequences of the viral strains but does not require structural information. For PGT123, CS predicted 6 and MI predicted 3 positions, overlapping in positions 297, 332, 334. Ferguson2013 (computational epitope prediction, broad neutralizer)
• PGT126: Clade A Env sequence, BG505, was identified to bind to bNAbs representative of most of the known NAb classes. This sequence is the best natural sequence match (73%) to the MRCA sequence from 19 Env sequences derived from PG9 and PG16 MAbs' donor. A point mutation at position L111A of BG505 enabled more efficient production of a stable gp120 monomer, preserving the major neutralization epitopes. The antisera produced by this adjuvanted formulation of gp120 competed with bnAbs from 3 classes of non-overlapping epitopes. PGT126 showed very high neutralization titer against BG505 pseudovirus in a competitive binding assay as shown in Table 1. Hoffenberg2013 (antibody interactions, glycosylation, neutralization)
• PGT126: Diversity of Ab recognition at the N332 site was assessed using chimeric antibodies made of heavy and light chains of N332-directed bNAbs PGT121-137. Recognition was good when heavy and light chains came from the same donor, and poor when they came from different donors, indicating multiple modes of recognition. Pancera2013a (chimeric antibody)
• PGT126: "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 PGT128-like cluster. Georgiev2013 (neutralization)
• PGT126: This study uncovered a potentially significant contribution of V_H replacement products which are highly enriched in IgH genes for the generation of anti-HIV Abs including anti-gp41, anti-V3 loop, anti-gp120, CD4i and PGT Abs. IgH encoding PGT Abs are likely generated from multiple rounds of V_H replacements. The details of PGT126 V_H replacement products in IgH gene and mutations and amino acid sequence analysis are described in Table 1, Table 2 and Fig 4. Liao2013a (antibody sequence)
• PGT126: Identification of broadly neutralizing antibodies, their epitopes on the HIV-1 spike, the molecular basis for their remarkable breadth, and the B cell ontogenies of their generation and maturation are reviewed. Ontogeny and structure-based classification is presented, based on MAb binding site, type (structural mode of recognition), class (related ontogenies in separate donors) and family (clonal lineage). This MAb's classification: gp120 glycan-V3 site, type penetrating CDR H3 binds two glycans and strand, PGT128 class, PGT128 family. Kwong2012 (review, structure, broad neutralizer)
• PGT126: This review discusses how analysis of infection and vaccine candidate-induced antibodies and their genes may guide vaccine design. This MAb is listed as V3 epitope involving carbohydrates bnAb, isolated after 2009 by neutralization screening of cultured, unselected IgG+ memory B cells. Bonsignori2012b (vaccine antigen design, vaccine-induced immune responses, review)
• PGT126: Glycan shield of HIV Env protein helps to escape the Ab recognition. Several of the PGT BnAbs interact directly with the HIV glycan coat. Crystal structures of Fabs PGT127 and PGT128 showed that the high neutralizing potency was mediated by cross-linking Env trimers on the viral surface. PGT126 binds to Man8/9 glycans on gp120 and potently neutralize across the clades. Pejchal2011 (glycosylation, structure, broad neutralizer)
• PGT126: Glycan Asn332-targeting broadly cross-neutralizing (BCN) antibodies were studied in 2 C-clade infected women. The ASn332 glycan was absent on infecting virus, but the BCN epitope with Asn332 evolved within 6 months though immune escape from earlier antibodies. Plasma from the subject CAP177 neutralized 88% of a large multi-subtype panel of 225 heterologous viruses, whereas CAP 314 neutralized 46% of 41 heterologous viruses but failed to neutralize viruses that lack glycan at 332. PGT126 targets Asn332 to neutralize. Moore2012 (neutralization, escape)
• PGT126: Neutralizing antibody repertoires of 4 HIV-infected donors with remarkably broad and potent neutralizing responses were probed. 17 new monoclonal antibodies that neutralize broadly across clades were rescued. These MAbs were not polyreactive. All MAbs exhibited broad cross-clade neutralizing activity, but several showed exceptional potency. PGT126 neutralized 52% of 162 isolates from major HIV clades at IC50<50 μg/ml, which was lower than 93% by VRC01, but the median antibody concentration required to inhibit HIV activity by 50% or 90% (IC50 and IC90 values) was almost 10-fold lower (that is, more potent) that of PG9, VRC01 and PGV04, and 100-fold lower than that of b12, 2G12 and 4E10. PGT MAbs 121-123, 130, 131 and 135-137 bound to monomeric gp120 and competed with glycan-specific 2G12 MAb and all MAbs except PGT 135-137 also competed with a V3-loop-specific antibody and did not bind to gp120ΔV3, suggesting that their epitopes are in proximity to or contiguous with V3. Glycan array analysis revealed that PGT MAbs 125–128 and 130 bound specifically to both Man8GlcNAc2 and Man9GlcNAc2, whereas the remaining antibodies showed no detectable binding to high-mannose glycans. Alanine substitution analysis suggested that N-linked glycans at positions 332 and/or 301 were important for neutralization by PGT MAbs 125–128, 130 and 131, suggesting their direct involvement in epitope formation.
