Furthermore, no significant NKG2D-ligand expression was detected on NKG2D-CAR T cells or Empty control T cells (Figure 6B) at the time of use in functional assays and NKG2D-CAR T cell viability after 24 h co-culture with AML (n=2) or T-ALL (n=2) cell lines was excellent (Figure 6C). Here, KLRK1 is linked to acute lymphoblastic leukemia.
