Blockade of MICA-mediated NK cell activation by soluble NKG2D bvFab. Human recombinant MICA protein and/or anti-2B4 mAb (ratio 1/1) were immobilized on microplates. IL2-stimulated human NK cells and soluble antibodies (150 nM) were then added. After 2 h of incubation, NK cell activation was assessed by quantification of cell surface CD107a by flow cytometry. The percentage of CD107a-positive NK cells obtained in the presence of MICA and anti-2B4 mAb without any soluble anti-NKG2D mAb was normalized to 100%. Ctl = soluble anti-NKG2D mAb. Irrel = FMDV bvFab. Each bar represents the mean value ± SD of 2 independent experiments
