While AML blasts in the peripheral blood of mice still expressed CD123 post therapy with CD123-ENG or CD123-ENG.IL15 T-cells, the surface density (estimated by mean fluorescence intensity) was lower than AML blasts from mice that had received NT or CD19-ENG.IL15 T-cells, or no therapy (Figures S9A–C). Here, IL15 is linked to acute myeloid leukemia.
