Rational Design of Envelope Identifies Broadly Neutralizing Human Monoclonal Antibodies to HIV-1

Designer Anti-HIV Developing a protective HIV vaccine remains a top global health priority. One strategy to identify potential vaccine candidates is to isolate broadly neutralizing antibodies from infected individuals and then attempt to elicit the same antibody response through vaccination (see the Perspective by Burton and Weiss ). Wu et al. (p. 856 , published online 8 July) now report the identification of three broadly neutralizing antibodies, isolated from an HIV-1–infected individual, that exhibited great breadth and potency of neutralization and were specific for the co-receptor CD4-binding site of the glycoprotein 120 (gp120), part of the viral Env spike. Zhou et al. (p. 811 , published online 8 July)…
