Identification and characterization of a neutralization site within the second variable region of human immunodeficiency virus type 1 gp120. J. Virol., 66:848-856, 1992. Two anti-envelope V2 antibodies were raised that neutralize virus in either a conformation dependent (G3-136) or conformation independent (BAT085) manner. G3-136 has diminished reactivity with deglycosylation or DTT reduced gp120, and sCD4 inhibits binding in a competition assay; BAT085 is not sensitive to these alterations in gp120.

Characterization of Conserved Human Immunodeficiency Virus Type 1 gp120 Neutralization Epitopes Exposed upon gp120-CD4 Binding. J. Virol., 67:3978-3988, 1993. Five regions are likely to contribute to the 48d and 17b discontinuous epitopes, either directly or through local conformational effects: the hydrophobic ring-like structure formed by the disulfide bond that links C3 and C4, the base of the stem-loop that contains V1 and V2, and the hydrophobic region in C2 from Arg 252 to Asp 262. Additionally changes in Glu 370, and Met 475 in C5, affected binding and neutralization. The hydrophobic character of these critical regions is consistent with the limited exposure on gp120 prior to CD4 binding. PubMed ID: 7685405. Show all entries for this paper.

MAb G3-4 binds a conformationally sensitive epitope in the V2 loop of HIV-1 RF. RF was cultured in the presence of G3-4 to select for neutralization resistance. Three independent experiments yielded escape mutants, and sequencing revealed two V2 mutations to be responsible for the neutralization escape phenotype, 177 Y/H and 179 L/P. Experimental introduction of the 179 P substitution resulted in non-viable virus, and 177 H confirmed the resistance phenotype. PubMed ID: 7507188. Show all entries for this paper.

This study suggests that antibodies specific for one of five different binding regions on gp120 are associated with viral neutralization: V2, V3, C4, the CD4 binding site, and a complex discontinuous epitope that does not interfere with CD4 binding. Kinetic binding properties of a set of MAbs that bind to these regions were studied, analyzing binding to both functional oligomeric LAI gp120 and soluble monomeric LAI BH10 gp120; neutralization ID$_50$s were also evaluated. It was found that the neutralization ID$_50$s was related to the ability to bind oligomeric, not monomeric, gp120, and concluded that with the exception of the V3 loop, regions of gp120 that are immunogenic will be poorly presented on cell-line-adapted virions. Further, the association rate, estimated as the t$_1/2$ to reach equilibrium binding to multimeric, virion associated, gp120, appears to be a major factor relating to affinity and potency of the neutralization response to cell-line-adapted virus.

Virol., 70:1863-1872, 1996. 46 anti-gp120 monomer MAbs were used to create a competition matrix, and MAb competition groups were defined. The data suggests that there are two faces of the gp120 glycoprotein: a face occupied by the CD4BS, which is presumably also exposed on the oligomeric envelope glycoprotein complex, and a second face which is presumably inaccessible on the oligomer and interacts with a number of nonneutralizing antibodies.

Poignard1996b P. Poignard, T. Fouts, D. Naniche, J. P. Moore, and Q. J. Sattentau. Neutralizing antibodies to human immunodeficiency virus type-1 gp120 induce envelope glycoprotein subunit dissociation. J. Exp. Med., 183:473-484, 1996. Binding of Anti-V3 and the CD4I neutralizing MAbs induces shedding of gp120 on cells infected with the T-cell line-adapted HIV-1 molecular clone Hx10. This was shown by significant increases of gp120 in the supernatant, and exposure of a gp41 epitope that is masked in the oligomer. MAbs binding either to the V2 loop or to CD4BS discontinuous epitopes do not induce gp120 dissociation. This suggests HIV neutralization probably is caused by several mechanisms, and one of the mechanisms may involve gp120 dissociation. PubMed ID: 8627160. Show all entries for this paper.

Analysis of the Interaction of the Human Immunodeficiency Virus Type 1 gp120 Envelope Glycoprotein with the gp41 Transmembrane Glycoprotein. J. Virol., 71:9722-9731, 1997. This study characterized the binding of gp120 and gp41 by comparing Ab reactivity to soluble gp120 and to a soluble complex of gp120 and gp41 called sgp140. The occlusion of gp120 epitopes in the sgp140 complex provides a guide to the gp120 domains that interact with gp41, localizing them in C1 and C5 of gp120. Mutations that disrupt the binding of the occluded antibodies do not influence NAb binding or CD4 binding, thus if the gp41 binding domain is deleted, the immunologically desirable features of gp120 for vaccine design are still intact.

Neutralization of human immunodeficiency virus type 1 by antibody to gp120 is determined primarily by occupancy of sites on the virion irrespective of epitope specificity. J. Virol., 72:3512-9, 1998. The authors propose that the occupancy of binding sites on HIV-1 virions is the major factor in determining neutralization, irrespective of epitope specificity. Neutralization was assayed T-cell-line-adapted HIV-1 isolates. Binding of Fabs to monomeric rgp120 was not correlated with binding to functional oligomeric gp120 or neutralization, while binding to functional oligomeric gp120 was highly correlated with neutralization. The ratios of oligomer binding/neutralization were similar for antibodies to different neutralization epitopes, with a few exceptions. PubMed ID: 9557629. Show all entries for this paper.

Most linear epitope MAbs in human sera are directed against the V3 region, and cross-reactive MAbs tend to be directed against discontinuous epitopes. PubMed ID: 7678308.

MAb G3-4 binds a conformationally sensitive epitope in the V2 loop of HIV-1 RF. RF was cultured in the presence of G3-4 to select for neutralization resistance. Three independent experiments yielded escape mutants, and sequencing revealed two V2 mutations to be responsible for the neutralization escape phenotype, 177 Y/H and 179 L/P.

This study suggests that antibodies specific for one of five different binding regions on gp120 are associated with viral neutralization: V2, V3, C4, the CD4 binding site, and a complex discontinuous epitope that does not interfere with CD4 binding. Kinetic binding properties of a set of MAbs that bind to these regions were studied, analyzing binding to both functional oligomeric LAI gp120 and soluble monomeric LAI BH10 gp120; neutralization ID$_50$s were also evaluated. It was found that the neutralization ID$_50$s was related to the ability to bind oligomeric, not monomeric, gp120, and concluded that with the exception of the V3 loop, regions of gp120 that are immunogenic will be poorly presented on cell-line-adapted virions. Further, the association rate, estimated as the t$_1/2$ to reach equilibrium binding to multimeric, virion associated, gp120, appears to be a major factor relating to affinity and potency of the neutralization response to cell-line-adapted virus.

Virol., 70:1863-1872, 1996. 46 anti-gp120 monomer MAbs were used to create a competition matrix, and MAb competition groups were defined. The data suggests that there are two faces of the gp120 glycoprotein: a face occupied by the CD4BS, which is presumably also exposed on the oligomeric envelope glycoprotein complex, and a second face which is presumably inaccessible on the oligomer and interacts with a number of nonneutralizing antibodies.

Neutralizing antibodies to human immunodeficiency virus type-1 gp120 induce envelope glycoprotein subunit dissociation. J. Exp. Med., 183:473-484, 1996. Binding of Anti-V3 and the CD4I neutralizing MAbs induces shedding of gp120 on cells infected with the T-cell line-adapted HIV-1 molecular clone Hx10. This was shown by significant increases of gp120 in the supernatant, and exposure of a gp41 epitope that is masked in the oligomer. MAbs binding either to the V2 loop or to CD4BS discontinuous epitopes do not induce gp120 dissociation. This suggests HIV neutralization probably is caused by several mechanisms, and one of the mechanisms may involve gp120 dissociation. PubMed ID: 8627160. Show all entries for this paper.

Analysis of the Interaction of the Human Immunodeficiency Virus Type 1 gp120 Envelope Glycoprotein with the gp41 Transmembrane Glycoprotein. J. Virol., 71:9722-9731, 1997. This study characterized the binding of gp120 and gp41 by comparing Ab reactivity to soluble gp120 and to a soluble complex of gp120 and gp41 called sgp140. The occlusion of gp120 epitopes in the sgp140 complex provides a guide to the gp120 domains that interact with gp41, localizing them in C1 and C5 of gp120. Mutations that disrupt the binding of the occluded antibodies do not influence NAb binding or CD4 binding, thus if the gp41 binding domain is deleted, the immunologically desirable features of gp120 for vaccine design are still intact.

The authors propose that the occupancy of binding sites on HIV-1 virions is the major factor in determining neutralization, irrespective of epitope specificity. Neutralization was assayed T-cell-line-adapted HIV-1 isolates. Binding of Fabs to monomeric rgp120 was not correlated with binding to functional oligomeric gp120 or neutralization, while binding to functional oligomeric gp120 was highly correlated with neutralization.

Identification and characterization of a neutralization site within the second variable region of human immunodeficiency virus type 1 gp120. J. Virol., 66:848-856, 1992. Two anti-envelope V2 antibodies were raised that neutralize virus in either a conformation dependent (G3-136) or conformation independent (BAT085) manner. G3-136 has diminished reactivity with deglycosylation or DTT reduced gp120, and sCD4 inhibits binding in a competition assay; BAT085 is not sensitive to these alterations in gp120.

Five regions are likely to contribute to the 48d and 17b discontinuous epitopes, either directly or through local conformational effects: the hydrophobic ring-like structure formed by the disulfide bond that links C3 and C4, the base of the stem-loop that contains V1 and V2, and the hydrophobic region in C2 from Arg 252 to Asp 262. Additionally changes in Glu 370, and Met 475 in C5, affected binding and neutralization.

Characterization of neutralizing monoclonal antibodies to linear and conformation-dependent epitopes within the first and second variable domains of human immunodeficiency virus type 1 gp120. J. Virol., 67:4932-4944, 1993. Substitutions in the V2 loop can result in complete dissociation of gp120 and gp41, suggesting alterations in V2 can affect subunit assembly. Other substitutions allowed gp120-gp41 association and expression, but inhibited viral entry or syncytia. Binding of some neutralizing MAbs was altered by V2 substitutions. For MAb CRA-4, changes at residues 191/192/193 (YSL/GSS), and for 11/68b, changes at residues 183/184 (PI/SG), within V2, and for both MAbs a position 435 (Y/H) change in C4, abrogate binding. These MAbs can bind to V1 and V2 domains in the absence of C4 domain, so the C4 substitution probably results in conformational change. PubMed ID: 7687306. Show all entries for this paper.

Virol., 70:1863-1872, 1996. 46 anti-gp120 monomer MAbs were used to create a competition matrix, and MAb competition groups were defined. The data suggests that there are two faces of the gp120 glycoprotein: a face occupied by the CD4BS, which is presumably also exposed on the oligomeric envelope glycoprotein complex, and a second face which is presumably inaccessible on the oligomer and interacts with a number of nonneutralizing antibodies.

A panel of Fabs was obtained from a library prepared from the bone marrow of a long-term asymptomatic HIV-1 seropositive male donor. Four Fabs recognize the CD4BS. An additional four Fabs were retrieved after epitope masking gp120 with the CD4BS Fabs at the screening stage. 3/4 of these Fabs bind to a V2 dependent conformational epitope. PubMed ID: 7529290.

Diverse epitopes are accessed by presenting gp120 to the library in different forms, such as sequential masking of epitopes with existing MAbs or sCD4 prior to selection or by selection on peptides. Fabs identified by these methods have specificities associated with epitopes presented poorly on native multimeric envelope. PubMed ID: 9126846. Show all entries for this paper.

Four of five anti-V3 MAbs were slightly cross-reactive within clade B, but not very reactive outside clade B. Two discontinuous CD4 binding site Mabs appear to be pan-reactive. Anti-V2 MAbs were only sporadically reactive inside and outside of clade B. PubMed ID: 7525988. Show all entries for this paper.

Thali1993 M. Thali, J. P. Moore, C. Furman, M. Charles, D. D. Ho, J. Robinson, and J. Sodroski. Characterization of Conserved Human Immunodeficiency Virus Type 1 gp120 Neutralization Epitopes Exposed upon gp120-CD4 Binding. J. Virol., 67:3978-3988, 1993. Five regions are likely to contribute to the 48d and 17b discontinuous epitopes, either directly or through local conformational effects: the hydrophobic ring-like structure formed by the disulfide bond that links C3 and C4, the base of the stem-loop that contains V1 and V2, and the hydrophobic region in C2 from Arg 252 to Asp 262. Additionally changes in Glu 370, and Met 475 in C5, affected binding and neutralization. The hydrophobic character of these critical regions is consistent with the limited exposure on gp120 prior to CD4 binding. PubMed ID: 7685405. Show all entries for this paper.

CD4-Dependent, Antibody-Sensitive Interactions between HIV-1 and Its Co-Receptor CCR-5. Nature, 384:184-187, 1996. CCR-5 is a co-factor for fusion of HIV-1 strains of the non-syncytium-inducing (NSI) phenotype with CD4+ T-cells. CD4 binding greatly increases the efficiency of gp120-CCR-5 interaction. Neutralizing MAbs against the V3 loop and CD4-induced epitopes on gp120 inhibited the interaction of gp120 with CCR-5, without affecting gp120-CD4 binding. PubMed ID: 8906796.

Characterization of Mutants of Human Immunodeficiency Virus Type 1 That Have Escaped Neutralization by Monoclonal Antibody G3-4 to the gp120 V2 Loop. J. Virol., 68:974-978, 1994. MAb G3-4 binds a conformationally sensitive epitope in the V2 loop of HIV-1 RF. RF was cultured in the presence of G3-4 to select for neutralization resistance. Three independent experiments yielded escape mutants, and sequencing revealed two V2 mutations to be responsible for the neutralization escape phenotype, 177 Y/H and 179 L/P. Experimental introduction of the 179 P substitution resulted in non-viable virus, and 177 H confirmed the resistance phenotype. PubMed ID: 7507188. Show all entries for this paper.
