Science, 280:1949-1953, 1998. This paper compares the epitope for CD4 inducible MAbs with the chemokine co-receptor binding site on the gp120 molecule. Site-directed mutagenesis of YU2 Env was guided by information obtained from the crystallized CD4-17b-gp120 core structure, Kwong et al, 1998. YU2 is a primary macrophage tropic R5 isolate with high affinity for both CD4 and CCR5. A protein with the V1-V2 loops deleted, called wt$\Delta$ was the basis for the assay which detected binding of virus to cells expressing CCR5 in the presence of sCD4. Preincubaton with MAb 17b blocks binding, as did the natural ligand for CCR5, MIP-1$\beta$ and anti-CCR5 MAb 2D7. Mutations 437 P/A and 442 Q/L increased CCR5 binding affinity. The region of gp120 CCR5 binding is shown to be the highly conserved $\beta$-sheet bridging structure, located proximal to the V3 loop. PubMed ID: 9632396. Show all entries for this paper.

CD4-Induced Conformational Changes in the Human Immunodeficiency Virus Type 1 gp120 Glycoprotein: Consequences for Virus Entry and Neutralization. J. Virol., 72:4694-4703, 1998. A study of the sCD4 inducible MAb 17bi, and the MAb CG10 that recognizes a gp120-CD4 complex. These epitopes are minimally accessible upon attachment of gp120 to the cell. The CD4-binding induced changes in gp120 were studied, exploring the sequestering of chemokine receptor binding sites from the humoral response. PubMed ID: 9573233. Show all entries for this paper.

Wu1996 L. Wu, N. P. Gerard, R. Wyatt, H. Choe, C. Parolin, N. Ruffing, A. Borsetti, A. A. Cardoso, E. Desjardin, W. Newman, C. Gerard, and J. Sodroski. CD4-Induced Interaction of Primary HIV-1 gp120 Glycoproteins with the Chemokine Receptor CCR-5. Nature, 384:179-183, 1996. Results suggest that HIV-1 attachment to CD4 creates a high-affinity binding site for CCR-5, leading to membrane fusion and virus entry. CD4-induced or V3 neutralizing MAbs block the interaction of gp120-CD4 complexes with CCR-5. PubMed ID: 8906795. Show all entries for this paper.
