WhiteScharf1993 M. E. White-Scharf, B. J. Potts, L. M. Smith, K. A. Sokolowski, J. R. Rusche, and S. Silver. Broadly Neutralizing Monoclonal Antibodies to the V3 Region of HIV-1 Can Be Elicited by Peptide Immunization. Virology, 192:197-206, 1993. Using a V3 loop peptide as immunogen, a panel of 50 anti-V3 neutralizing monoclonal antibodies were generated. Four of them were characterized in detail in this paper. PubMed ID: 7685962.

Bou-Habib1994 D. C. Bou-Habib, G. Roderiquez, T. Oravecz, P. W. Berman, P. Lusso, and M. A. Norcross. Cryptic Nature of Envelope V3 Region Epitopes Protects Primary Monocytotropic Human Immunodeficiency Virus Type 1 from Antibody Neutralization. J. Virol., 68:6006-6013, 1994. This paper shows that antibodies to the tip of the V3 loop fail to neutralize primary isolate JR-CSF, and that the V3 loop is far more accessible on the JR-CSF derived T-cell tropic strain T-CSF. Anti-V3 antibodies successfully neutralize T-CSF. Weak binding of anti-V3 antibodies to the primary isolate JR-CSF suggests the V3 loop is accessible only in a minor fraction of proteins.

LaCasse1998 R. A. LaCasse, K. E. Follis, T. Moudgil, M. Trahey, J. M. Binley, V. Planelles, S. Zolla-Pazner, and J. H. Nunberg. Coreceptor utilization by human immunodeficiency virus type 1 is not a primary determinant of neutralization sensitivity. J. Virol., 72:2491-5, 1998. A T-cell line-adapted (TCLA) derivative of SI primary isolate 168P acquired the ability to to be neutralized by anti-V3 MAbs 257-D, 268-D and 50.1. The primary isolate could use either CCR5 or CXCR4, and was not neutralized when infection was directed via either pathway, but the TCLA derivative uses CXCR4 only and is neutralized. Thus coreceptor usage is not the primary determinant of differential neutralization sensitivity in primary versus TCLA strains. PubMed ID: 9499111. Show all entries for this paper.

Moore1994b J. P. Moore, F. E. McCutchan, S.-W. Poon, J. Mascola, J. Liu, Y. Cao, and D. D. Ho. Exploration of Antigenic Variation in gp120 from Clades A through F of Human Immunodeficiency Virus Type 1 by Using Monoclonal Antibodies. J. Virol., 68:8350-8364, 1994. Four of five anti-V3 MAbs were slightly cross-reactive within clade B, but not very reactive outside clade B. Two discontinuous CD4 binding site Mabs appear to be pan-reactive. Anti-V2 MAbs were only sporadically reactive inside and outside of clade B. PubMed ID: 7525988. Show all entries for this paper.

Virology, 197:415-419, 1993. Four anti-V3 loop MAbs, (59.1, 83.1, 50.1, and 58.2), were evaluated for their affinity, neutralization potencies, and their ability to synergize F105 or sCD4 neutralization. The most important parameter for synergy was the capacity to neutralize a given virus independently. PubMed ID: 8212576. Show all entries for this paper.

Reitz, Jr. Alteration of V3 Loop Context within the Envelope of Human Immunodeficiency Virus Type 1 Enhances Neutralization. J. Virol., 68:3459-3466, 1994. MN-V3 loop inserted into a HBX2 background results in enhanced neutralization of anti-MN V3 MAb 50.1 and human HIV+ sera when the chimeric virus was compared to MN. Enhanced affinity, and greater proportions of labeled infected H9 cells by FACS analysis, were also observed using two anti-MN V3 MAbs, 50.1 and 83.1. PubMed ID: 7514675.

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.

Lack of Induction of Antibodies Specific for Conserved, Discontinuous Epitopes of HIV-1 Envelope Glycoprotein by Candidate AIDS Vaccines. J. Immunol., 155:4100-4110, 1995. 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 may explain the inability of the vaccinee sera to neutralize primary HIV-1 isolates. PubMed ID: 7561123. Show all entries for this paper.
