Immunochemical Analysis of the gp120 Surface Glycoprotein of Human Immunodeficiency Virus Type 1: Probing the Structure of the C4 and V4 Domains and the Interaction of the C4 Domain with the V3 Loop. 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. Some V3-C4 domain interaction was indicated based on mutation and interference studies. PubMed ID: 7687303. 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.

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.
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.

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.
