A short segment of the HIV-1 gp120 V1/V2 region is a major determinant of resistance to V1/V2 neutralizing antibodies.

Journal Article

Antibody PG9 is a prototypical member of a class of V1/V2-directed antibodies that effectively neutralizes diverse strains of HIV-1. We analyzed strain-specific resistance to PG9 using sequence and structural information. For multiply resistant strains, mutations in a short segment of V1/V2 resulted in gain of sensitivity to PG9 and related V1/V2 neutralizing antibodies, suggesting both a common mechanism of HIV-1 resistance to and a common mode of recognition by this class of antibodies.
