Phenotypic analysis of CAR engineered memory like NK cells. (A) Representative flow cytometry plots showing the distribution of NK cell subtypes in CAR modified memory-like NK cells based on the relative expression of CD56 and CD16 (n = 4). (B) Evolution of CD56bright CD16+, CD56bright CD16-, CD56dim CD16+ and CD56dim CD16- NK cell subsets in CAR MLNK cells and CAR NK cells over time (n = 4). (C) Expression levels of KIR2DL1, CD94, NKp30, NKp46, NKG2A, NKG2D, NKG2C, CD25, PD1 and TIM3 on CAR MLNK cells and conventional CAR NK cells (n = 4). *P < 0.05; **P < 0.01; ns, no significance.
