DSouza1995 M. P. D'Souza, G. Milman, J. A. Bradac, D. McPhee, C. V. Hanson, and R. M. Hendry. Neutralization of Primary HIV-1 Isolates by Anti-Envelope Monoclonal Antibodies. AIDS, 9:867-874, 1995. Eleven labs tested the 6 human MAbs 1125H, TH9, 4.8D, 257-D-IV, TH1, 2F5, and also HIVIG for neutralization of MN, JRCSF, the two B clade primary isolates 301657 and THA/92/026, and the D clade isolate UG/92/21. 2F5 was the most broadly neutralizing, better than HIVIG. The other MAbs showed limited neutralization of only MN (anti-CD4BS MAbs 1125H, TH9, and 4.8D), or MN and JRCSF (anti-V3 MAbs 257-D-IV and TH1). PubMed ID: 7576320. Show all entries for this paper.

A panel of anti-gp160 MAbs to was used to construct anti-HIV immunotoxins by coupling antibodies to ricin A chain (RAC). The ability of the immunotoxins to kill HIV-1-infected cells was tested in tissue culture. Immunotoxins that bind epitopes on the cell surface killed infected cells, although killing was not directly proportional to binding. The activity of anti-gp41 immunotoxins was markedly enhanced in the presence of sCD4. PubMed ID: 8827220. Show all entries for this paper.

Relationship of the Human Immunodeficiency Virus Type 1 gp120 Third Variable Loop to Elements of the CD4 Binding Site. J. Virol., 66:6997-7004, 1992. 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.
