LAMP1 and acute myeloid leukemia: Using different in vitro models of CAR123 co-culture with BPDCN and AML cell lines, we show that both TKIs reduce CAR123 activation phenotype (CD69 and CD25), tumor necrosis factor α (TNF-α) and interferon-γ (IFN-γ) secretion; degranulation (CD107a); and killing of leukemia cells.
