Their study proved the anti-AML activity of GRP78-CAR T cells in vivo by injection of 5 × 103 MOLM13 AML cells following 3 × 106 CAR T cells on day 7, whereas our study demonstrated that 5 × 106 GRP78-CAR T cells can eradicate explanted 1 × 106 of U937 or KG1a AML cells in the xenograft mouse models. Here, HSPA5 is linked to acute myeloid leukemia.
