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.

Mapping the Protein Surface of Human Immunodeficiency Virus Type 1 gp120 Using Human Monoclonal Antibodies from Phage Display Libraries. J. Mol. Biol., 267:684-695, 1997. (Genbank: U82767 U82768 U82769 U82770 U82771 U82772 U82942 U82943 U82944 U82945 U82946 U82947 U82948 U82949 U82950 U82951 U82952 U82961 U82962) Recombinant monoclonal antibodies from phage display libraries provide a method for Env surface epitope mapping. 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.

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.

Loss of a Neutralizing Epitope by a Spontaneous Point Mutation in the V3 Loop of HIV-1 Isolated from an Infected Laboratory Worker. J. Biol. Chem., 268:25894-25901, 1993. The MAb M77 cannot neutralize a virus isolated from a IIIB infected lab-worker that has a single point mutation in the defined linear epitope. M77 cannot bind to the mutant native gp120, but can bind to a peptide that carries the substitution. PubMed ID: 7503990. 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.
