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.

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., 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.

Retroviruses, 12:901-909, 1996. Mice were injected with the gp120 in different configurations: free, complexed with CD4, and as an immunocomplex bound to a V3 loop MAb (M77) of the protein. Polyclonal sera, as well as monoclonal antibodies produced in each case, were analyzed. The free gp120 and gp120-CD4 complex immunogens stimulated responses were directed mainly toward conformational epitopes, but gp120 immunocomplexed with MAb M77 also produced numerous and varied MAbs directed toward linear epitopes that were presumably inaccessible on the gp120, gp120-CD4 proteins.

Monoclonal Antibodies Raised against Covalently Crosslinked Complexes of Human Immunodeficiency Virus Type 1 gp120 and CD4 Receptor Identify a Novel Complex-Dependent Epitope on gp120. Virology, 211:583-588, 1995. To explore the immunogenicity of regions of gp120 that are exposed due to conformational changes in gp120 upon CD4 binding, CD4 was covalently linked to gp120 and this complex was used as an immunogen for BALB/c mice. Two MAbs were produced, both of which bind preferentially to the gp120-CD4 complex, and are conformational. Competition assays indicate these MAbs bind to epitopes that are recognized by sera from HIV-1 infected humans. PubMed ID: 7544051. Show all entries for this paper.

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.

Monoclonal Antibodies Raised against Covalently Crosslinked Complexes of Human Immunodeficiency Virus Type 1 gp120 and CD4 Receptor Identify a Novel Complex-Dependent Epitope on gp120. Virology, 211:583-588, 1995. To explore the immunogenicity of regions of gp120 that are exposed due to conformational changes in gp120 upon CD4 binding, CD4 was covalently linked to gp120 and this complex was used as an immunogen for BALB/c mice. Two MAbs were produced, both of which bind preferentially to the gp120-CD4 complex, and are conformational. Competition assays indicate these MAbs bind to epitopes that are recognized by sera from HIV-1 infected humans. PubMed ID: 7544051. 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.
