b6: This study assessed the ADCC activity of antibodies of varied binding types, including CD4bs (b6, b12, VRC01, PGV04, 3BNC117), V2 (PG9, PG16), V3 (PGT126, PGT121, 10-1074), oligomannose (2G12), MPER (2F5, 4E10, 10E8), CD4i (17b, X5), C1/C5 (A32, C11), cluster I (240D, F240), and cluster II (98-6, 126-7). ADCC activity was correlated with binding to Env on the surfaces of virus-infected cells. ADCC was correlated with neutralization, but not always for lab-adapted viruses such as HIV-1 NLA-3. MAb b6 had strong ADCC activity against cells infected with 1 of 3 strains tested. vonBredow2016 (ADCC)
b6: A panel of NAbs and non-neutralizing Abs (NoNAbs) displaying the highest Fc γR-mediated inhibitory activity and significant ADCC were selected and formulated in a microbicidal gel and tested for their antiviral activity against SHIVSF162P3 vaginal challenge in non-human primates. Combination of 2G12, 2F5 and 4E10 fully prevented vaginal transmission. Two NoNAbs 246-D and 4B3 had no impact on viral acquisition, but reduced plasma viral load. Moog2014 (ADCC, SIV)
