Cao1997 J. Cao, N. Sullivan, E. Desjardin, C. Parolin, J. Robinson, R. Wyatt, and J. Sodroski. Replication and Neutralization of Human Immunodeficiency Virus Type 1 Lacking the V1 and V2 Variable Loops of the gp120 Envelope Glycoprotein. J. Virol., :9808-9812, 1997. An HIV-1 mutant lacking the V1-V2 loops can replicate in Jurkat cells and revertants that replicate with wild-type efficiency rapidly evolve in culture. These viruses exhibited increased neutralization susceptibility to V3 loop or CD4i MAbs, but not to sCD4 or anti-CD4BS MAbs. Thus the gp120 V1 and V2 loops protect HIV-1 from some subsets of neutralizing antibodies. PubMed ID: 9371651. Show all entries for this paper.

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.

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.

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.

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.

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.

This was measured on HIV-1-infected cells by the increased binding of gp120/V3 loop specific MAbs, and on the surface of virions by increased cleavage of the V3 loop by an exogenous proteinase.

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.

Neutralizing Antibodies to an Immunodominant Envelope Sequence Do Not Prevent gp120 Binding to CD4. J. Virol., 62:4195-4200, 1988. This report was an early suggestion that there are at least two classes of biologically active antibodies to HIV: one class is isolate restricted, primarily directed to a hypervariable loop structure of gp120 and not involved in CD4 binding; the second class is directed at more conserved structures that may directly block CD4 binding.

MAb 9284, directed at the V3 loop of gp120, failed to inhibit the infection of CD-4 negative cells with pseudotypes, but anti-HTLV serum did inhibit infection.

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.

A T->A amino acid substitution at position 582 of gp41 conferred resistance to neutralization to 30\% of HIV positive sera (Wilson et al. J Virol 64:3240-48 (1990)). Monoclonal antibodies that bound to the CD4 binding site were unable to neutralize this virus, but the mutation did not reduce the neutralizing capacity of a V2 region MAb G3-4, V3 region MAbs, or gp41 neutralizing MAb 2F5.

Dissociation Rate of Antibody-gp120 Binding Interactions Is Predictive of V3-Mediated Neutralization of HIV-1. J. Immunol., 153:449-459, 1994. Using surface plasmon resonance it was found that the rate of the dissociation of the MAb-gp120 complex, but not the association rate, correlated with MAbs ability to neutralize homologous virus (measured by 50\% inhibition of p24 production). Association constants were similar for all MAbs tested, varying less than 4-fold. Dissociation rate constants were quite variable, with 100-fold differences observed. PubMed ID: 7515931.

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.

This paper examines mutations which alter MAb binding and neutralization. Anti-V3 MAb 9284 has enhanced binding due to a mutation in the C4 region that is also important for CD4 binding, and anti-CD4 binding MAbs F105, 1.5e and 1125H show increased precipitation of a gp120 from which the V3 loop was deleted, relative to wild type, in RIPA buffer containing non-ionic detergents.

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.

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.

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.

Virol., 67:53-59, 1993. This study looked at the ability of 16 human MAbs to activate complement. MAbs directed against the V3 region could induce C3 deposition on infected cells and virolysis of free virus, but antibodies to the CD4BS and C-terminal region and two regions in gp41 could induce no complement mediated effects. Pre-treatment with sCD4 could increase complement-mediated effects of anti-gp41 MAbs, but decreased the complement-mediated effects of V3 MAbs. Anti-gp41 MAbs were able to affect IIIB but not MN virolysis, suggesting spontaneous shedding of gp120 on IIIB virions exposes gp41 epitopes.

The new method involves using MAbs to the host proteins incorporated into virions to bind them to ELIZA plates. Antigenic conservation in epitopes of HIV-1 in clades A, B, D, F, G, and H was studied. MAbs were selected that were directed against V2, V3, CD4bd, C5 or gp41 regions. Antibodies against V2, the CD4BS, and sp41 showed weak and sporadic reactivities, while binding strongly to gp120, suggesting these epitopes are hidden when gp120 is in its native, quaternary structure.

Med., 174:407-415, 1991. sCD4 binding to gp120 induces conformational changes within envelope oligomers. This was measured on HIV-1-infected cells by the increased binding of gp120/V3 loop specific MAbs, and on the surface of virions by increased cleavage of the V3 loop by an exogenous proteinase.

Most gp41 epitopes are masked when associated with gp120 on the cell surface. Weak binding of anti-gp41 MAbs can be enhanced by treatment with sCD4. MAb 2F5 binds to a membrane proximal epitope which binds in the presence of gp120 without sCD4. PubMed ID: 7530400. Show all entries for this paper.

Virol., 67:53-59, 1993. This study looked at the ability of 16 human MAbs to activate complement. MAbs directed against the V3 region could induce C3 deposition on infected cells and virolysis of free virus, but antibodies to the CD4BS and C-terminal region and two regions in gp41 could induce no complement mediated effects. Pre-treatment with sCD4 could increase complement-mediated effects of anti-gp41 MAbs, but decreased the complement-mediated effects of V3 MAbs. Anti-gp41 MAbs were able to affect IIIB but not MN virolysis, suggesting spontaneous shedding of gp120 on IIIB virions exposes gp41 epitopes. IgG isotype did not appear to have an effect on virolysis or C3 deposition. PubMed ID: 7677959. Show all entries for this paper.

Tani1994 Y. Tani, E. Donoghue, S. Sharpe, E. Boone, H. C. Lane, S. Zolla-Pazner, and D. I. Cohen. Enhanced In Vitro Human Immunodeficiency Virus Type 1 Replication in B Cells Expressing Surface Antibody to the TM Env Protein. J. Virol., 68:1942-1950, 1994. The MAb 98-6 was expressed as a surface anti-gp41 monoclonal antibody receptor for gp41 (sIg/gp41) by transfection into a CD4-negative B-cell line. Transfected cells could bind HIV envelope, but could not be infected by HIV-1. When CD4 delivered by retroviral constructs was expressed on these cells, they acquired the ability to replicate HIV-1, and sIg/gp41 specifically enhanced viral replication. PubMed ID: 8107254.
