NKI-L16 also induces an enhancement of HIV-1-dependent syncytium formation in PBMCs. Ficoll-Hypaque-isolated PBMCs were incubated in the absence (A) or presence (B) of NKI-L16 for 30 min before the addition of an equal number of J1.1 cells. After 36 h of incubation, light microscopy observation was performed and photographs were taken at ×100 magnification. Arrows point to syncytia.
