The antibody-dependent cell-mediated cytotoxicity (ADCC) mechanism involves both innate and adaptive immune systems. While a number of epitope mapping studies of neutralizing (Nt) antibodies and cytotoxic T lymphocyte (CTL) against a variety of HIV-1 clades have been reported, there has been a paucity of similar studies aimed at identifying epitopes of ADCC-inducing antibodies. Herein we screened 35 sera from HIV-1 CRF01_AE-infected blood donors for ADCC antibody activity against gp120 utilizing an EGFP-CEM-NK ^r flow cytometric assay. Eighteen sera with high ADCC antibody activity were then comprehensively examined for ADCC antibody epitopes using the HIV-1 subtype CRF01_AE TH023 gp120 peptide set consisting of 126 peptides of 15 amino acids in length, overlapping by 11 amino acids. This peptide set was divided into five pools (E1–E5). Each positive peptide pool was further investigated for fine epitope mapping of ADCC antibody activity using a 5 by 5 peptide matrix format. Interestingly, six and three peptides from peptide pools E1 and E2, respectively, responded to at least 33.33% of the tested sera. These nine common ADCC epitopes were localized to the C1 and V2 region of gp120. Furthermore, 5/9 epitopes were also shown to serve as full or partial Nt antibody targets for HIV-1 subtypes B and CRF01_AE. We submit these data on epitope mapping of ADCC or dual ADCC-Nt antibodies against HIV-1 gp120 that should be considered in the formulation of vaccines against HIV-1.
