Abstract

OBJECTIVE: To determine monoclonal antibody (mAb) features that predict Fc-mediated effector functions against HIV. DESIGN: Monoclonal antibodies, derived from Chinese hamster ovary cells or EBV-immortalized mouse heteromyelomas, with specificity to key regions of the HIV envelope including gp120-V2, gp120-V3 loop, gp120-CD4 binding site, and gp41-specific antibodies, were functionally profiled to determine the relative contribution of the variable and constant domain features of the antibodies in driving robust Fc-effector functions. METHODS: Each mAb was assayed for antibody-binding affinity to gp140, antibody -dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosi..
