Building Better HIV Antibodies

Current advances in isolating antibodies from HIV-infected individuals have allowed for the discovery of a large number of new, broadly neutralizing anti-HIV antibodies directed against the host receptor (CD4) binding site—a functional site on the surface of the virus that allows for cell entry and infection. Using a technique known as structure-based rational design, the team modified one already-known and particularly potent antibody—NIH45-46—so that it can target the binding site in a different and more powerful way. A study outlining their process was published in the October 27 issue of Science Express.
