Neutralization of two R5-tropic SHIVs with a panel of 11 broadly acting anti–HIV-1 mAbs. (A and C) Neutralization was performed with SHIVAD8EO (A) or SHIVDH12-V3AD8 (C) pseudovirions and the indicated mAbs using TZM-bl target cells. The titration curves for the glycan-dependent neutralizing mAbs are red; for VRC01 in blue; and two potent CD4bs mAbs (45-46m2 and 3BNC117) in green. (B and D) The calculated IC50 values for neutralizing SHIVAD8EO (B) or SHIVDH12-V3AD8 (D) are shown below. The individual assays were repeated three times.
