Killing by MR1-M3Ade tetramer-positive T cell lines from D5 and D6 of healthy monocytes and B cells compared with the tumor cell line TF-1. The results from two independent experiments are shown. Symbols represent target cells from four different healthy individuals. The right panels of each donor show the killing SD of TF-1 cells with varying numbers of effector cells anti-MR1 mAbs. See alsoFigure S3.
