Second, the expression patterns of TIGIT on γδ T and its subset cells were different from NKG2D expression, which showed HIs (median: 19.50%) < AML-CR (median: 27.1%) < AML-DN group (median: 58.20%) (Figure 2D; Supplementary Figure S2). This evidence concerns the gene KLRK1 and acute myeloid leukemia.
