Figure Lengend Snippet: a, Degranulation (percentage of CD107a+ cells) of primary NKG2A+NKG2C− NK cells (denoted as NKG2A+C−) after incubation with .221-SPE*01:03 target cells measured for healthy blood donors (n = 8) and the corresponding inhibition of degranulation. Inhibition of degranulation was calculated using the percentage of CD107a+ data as: (1 − (sample − neg_ctrl)/(pos_ctr − neg_ctrl)) × 100, where neg_ctrl represents NK cells incubated without target cells (Target–), and pos_ctrl represents NK cells incubated with .221 cells expressing transgenic HLA-E*01:03 with its own SP. b, Correlation between JurkatNKG2A activity (Fig. 2c) and primary NKG2A+NKG2C− NK cell inhibition (a) after incubation with .221-SPE*01:03 cells. c, Degranulation of primary NKG2A−NKG2C+ NK cells (denoted as NKG2A−C+) after incubation with .221-SPE*01:03 target cells measured for the same donors (n = 8) as in a. d, Correlation between JurkatNKG2C activity (Fig. 2c) and primary NKG2A−NKG2C+ NK cell activity (c) after incubation with .221-SPE*01:03 cells. e, NKL cell degranulation after incubation with .221-SPE*01:03 target cells and the corresponding inhibition of degranulation calculated based on the percentage of CD107a+ cells data. Data are mean ± s.d. from triplicate experiments. f, Correlation between NKL cell inhibition (e) and JurkatNKG2A activity after incubation with .221-SPE*01:03 cells (Fig. 2c). g, Correlation between NKL cell inhibition (e) and primary NKG2A+NKG2C− NK cell inhibition (a). In a, c and e, P values were determined in comparison with target cells expressing SP-5B using a two-sided paired t-test for primary NK cells and an unpaired t-test for NKL cells. **P < 0.01, ***P < 0.001, ****P < 0.0001. In b, d, f and g, R2 was determined by Spearman correlation analysis and is shown with a two-tailed P value.

Figure Lengend Snippet: Jurkat reporter cells, primary NK cells from four healthy donors (HD), and NKL cells were stained with anti-NKG2A antibody (clone REA110). Flow cytometry histograms are shown on top, and graphical representation of the corresponding MFI data is shown below. The vertical line on the REA110 histogram separates NKG2A− from NKG2A+ populations. NKG2A expression levels are determined as MFI values of NKG2A+ cells obtained by REA110 staining minus MFI values obtained by isotype control staining for each cell type. (−) represents untransduced parental Jurkat cells.
