Veronese1992 F. di Marzo Veronese, R. Rahman, R. Pal, C. Boyer, J. Romano, V. S. Kalyanaraman, B. C. Nair, R. C. Gallo, and M. G. Sarngadharan. Delineation of immunoreactive, conserved regions in the external envelope glycoprotein of the human immunodeficiency virus type 1. AIDS Res. Hum. Retroviruses, 8:1125-1132, 1992. PubMed ID: 1380259.

Moore1994a J. P. Moore, Q. J. Sattentau, R. Wyatt, and J. Sodroski. Probing the Structure of the Human Immunodeficiency Virus Surface Glycoprotein gp120 with a Panel of Monoclonal Antibodies. J. Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. 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.

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.
Wyatt1997 R. Wyatt, E. Desjardin, U. Olshevsky, C. Nixon, J. Binley, V. Olshevsky, and J. Sodroski. 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.

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.

This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer.

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.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

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.

Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120.

V. Tolstikov. In Vitro Effects of Anti-HIV Immunotoxins Directed against Multiple Epitopes on HIV Type 1 Envelope Glycoprotein 160. AIDS Res. Hum. Retroviruses, 12:1041-1051, 1996. A panel of anti-gp160 MAbs to was used to construct anti-HIV immunotoxins by coupling antibodies to ricin A chain (RAC). The ability of the immunotoxins to kill HIV-1-infected cells was tested in tissue culture. Immunotoxins that bind epitopes on the cell surface killed infected cells, although killing was not directly proportional to binding. The activity of anti-gp41 immunotoxins was markedly enhanced in the presence of sCD4. PubMed ID: 8827220. 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.

Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

Virol., 201:206-214, 1994. Antibodies against GalCer can block infection of CD4-negative cells from the brain and colon that are susceptible to HIV infection. This paper explores the ability of a panel of MAbs to inhibit binding of gp120 to GalCer, and also of the binding of GalCer to inhibit MAb-gp120 interaction. MAbs to the V3 loop and GalCer showed mutual inhibition of binding to gp120, and anti-CD4 binding site MAbs showed reduced inhibition. N- and C-terminal MAbs didn't influence GalCer binding.

Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

Several Antigenic Determinants Exposed on the gp120 Moiety of HIV-1 gp160 Are Hidden on the Mature gp120. J. Immunol., 143:1832-1836, 1989. PubMed ID: 2476484. Show all entries for this paper.
Moore1993a J. P. Moore and D. D. Ho. Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

Cook1994 D. G. Cook, J. Fantini, S. L. Spitalnik, and F. Gonzalez-Scarano. Binding of Human Immunodeficiency Virus Type 1 HIV-1 gp120 to Galactosylceramide (GalCer): Relationship to the V3 Loop. Virol., 201:206-214, 1994. Antibodies against GalCer can block infection of CD4-negative cells from the brain and colon that are susceptible to HIV infection. This paper explores the ability of a panel of MAbs to inhibit binding of gp120 to GalCer, and also of the binding of GalCer to inhibit MAb-gp120 interaction. MAbs to the V3 loop and GalCer showed mutual inhibition of binding to gp120, and anti-CD4 binding site MAbs showed reduced inhibition. N- and C-terminal MAbs didn't influence GalCer binding.

Moore1994a J. P. Moore, Q. J. Sattentau, R. Wyatt, and J. Sodroski. Probing the Structure of the Human Immunodeficiency Virus Surface Glycoprotein gp120 with a Panel of Monoclonal Antibodies. J. Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

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.

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.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

Moore1994a J. P. Moore, Q. J. Sattentau, R. Wyatt, and J. Sodroski. Probing the Structure of the Human Immunodeficiency Virus Surface Glycoprotein gp120 with a Panel of Monoclonal Antibodies. J. Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Virol., 201:206-214, 1994. Antibodies against GalCer can block infection of CD4-negative cells from the brain and colon that are susceptible to HIV infection. This paper explores the ability of a panel of MAbs to inhibit binding of gp120 to GalCer, and also of the binding of GalCer to inhibit MAb-gp120 interaction. MAbs to the V3 loop and GalCer showed mutual inhibition of binding to gp120, and anti-CD4 binding site MAbs showed reduced inhibition. N- and C-terminal MAbs didn't influence GalCer binding.

Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

Y. H. Abacioglu, T. R. Fouts, J. D. Laman, E. Claassen, S. H. Pincus, J. P. Moore, C. A. Roby, R. Kamin-Lewis, and G. K. Lewis. Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

J. Virol., 73:4785-4796, 1993. General observations: C4 and V3 MAbs are sensitive to the way the epitopes are presented, and this sensitivity cannot be correlated to peptide binding.

Sattentau1995a Q. J. Sattentau and J. P. Moore. Human immunodeficiency virus type 1 neutralization is determined by epitope exposure on the gp120 oligomer. J. Exp. Med., 182:185-196, 1995. 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.
Wyatt1997 R. Wyatt, E. Desjardin, U. Olshevsky, C. Nixon, J. Binley, V. Olshevsky, and J. Sodroski. 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.

Parren1998 P. W. Parren, I. Mondor, D. Naniche, H. J. Ditzel, P. J. Klasse, D. R. Burton, and Q. J. Sattentau. 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.

Abacioglu1994 Y. H. Abacioglu, T. R. Fouts, J. D. Laman, E. Claassen, S. H. Pincus, J. P. Moore, C. A. Roby, R. Kamin-Lewis, and G. K. Lewis. Epitope Mapping and Topology of Baculovirus-Expressed HIV-1 gp160 Determined with a Panel of Murine Monoclonal Antibodies. AIDS Res. Hum. Retroviruses, 10:371-381, 1994. Thirty MAbs were obtained from BALB/c mice immunized with rgp160 LAI expressed in baculovirus. These antibodies map to 4 domains: gp120 C1, C2, C3/V4, and the cytoplasmic tail of gp41. All epitopes were exposed on rgp160 without denaturing the protein, but 6/8 epitopes mapped in gp120 are not exposed unless the protein is denatured, showing rgp160 and rgp120 fold differently.

Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120. The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Lack of Induction of Antibodies Specific for Conserved, Discontinuous Epitopes of HIV-1 Envelope Glycoprotein by Candidate AIDS Vaccines. J. Immunol., 155:4100-4110, 1995. The Ab response in both HIV-1 infected and uninfected volunteers immunized with HIV-1 rec envelope subunit vaccines (Genentech gp120IIIB, MicroGeneSys gp160IIIB, or ImmunoAG gp160IIIB) preferentially induced Abs reactive only to the denatured form of gp120.

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.

Moore1993a J. P. Moore and D. D. Ho. Antibodies to discontinuous or conformationally sensitive epitopes on the gp120 glycoprotein of human immunodeficiency virus type 1 are highly prevalent in sera of infected humans. J. Virol., 67:863-875, 1993. CD4BS antibodies are prevalent in HIV-1-positive sera, while neutralizing MAbs to C4, V2, and V3 and MAbs to linear epitopes are less common. 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.

J. Gen. Virol., 75:2089-2095, 1994. BALB/c mice were immunized with baculovirus expressed gp160 or gp120, and 15 MAbs were generated. No MAbs generated in this study neutralized reference strains, using a tetrazolium-based cytotoxicity assay to test for neutralization. Ten of the Mabs were mapped by peptide ELISA, and seven reacted with the C1 region, one with V2, one with V4, and one with the C-terminal end. PubMed ID: 7519249. Show all entries for this paper.

The authors suggest that a fivefold increase in the affinity for a MAb binding to denatured versus native gp120 indicates that the epitope is inaccessible in the native form. We also have included here information extracted from Moore et al's list of the gp120 mutations that reduced the binding of a particular MAb. In mapping of exposed regions of gp120, C2, C3, and C5 domain epitopes were found to bind preferentially to denatured gp120. V1, V2 and V3, part of C4, and the extreme carboxy terminus of C5 were exposed on the native monomer. In the oligomeric form of the molecule, only V2, V3 and part of C4 are well exposed as continuous epitopes. PubMed ID: 7504741. Show all entries for this paper.

Virol., 201:206-214, 1994. Antibodies against GalCer can block infection of CD4-negative cells from the brain and colon that are susceptible to HIV infection. This paper explores the ability of a panel of MAbs to inhibit binding of gp120 to GalCer, and also of the binding of GalCer to inhibit MAb-gp120 interaction. MAbs to the V3 loop and GalCer showed mutual inhibition of binding to gp120, and anti-CD4 binding site MAbs showed reduced inhibition. N- and C-terminal MAbs didn't influence GalCer binding.

Virol., 68:469-484, 1994. This study compared a large number of MAbs that bind to linear epitopes of gp120, and compared binding affinities for: i) native and SDS-DDT denatured gp120, (clone BH10 of the LAI isolate expressed in CHO cells); ii) recombinant gp120 lacking the V1, V2, V3 loops; iii) a panel of 20 mer peptides; iv) a panel of gp120 mutants; and v) oligomeric versus monomeric gp120. The binding ratio of native versus denatured monomeric gp120 is included in the table in this database. These numbers should be considered with the following points in mind: a continuous epitope may be partially exposed on the surface; and a preparation of rgp120 is not homogeneous and contains fully folded, partly denatured, and some completely unfolded species, so the conformation of what is considered to be a native protein will not only reflect fully folded gp120.

J. Immunol., 146:4315-4324, 1991. Six MAbs, (907, 924, 110.1, 41.1, 86 and P5-3) and polyclonal pooled serum antibodies purified on gp160 were coupled to RAC to create immunotoxins. Only 41.1-RAC, an anti-gp41 MAb-immunotoxin and the polyclonal immunotoxin showed direct activity against multiple strains, and activity of an immunotoxin was found not to be directly correlated with cell surface binding.
