Further frequencies of leukemia-specific, antitumor-directed immune cells [TgdTNFα/Tgd (Figure 3b), Tβ7IFNg/cells and Tβ7107a/cells (Figure 3b)] were borderline significantly higher in patients with RTI vs. without RTI (e.g., %TgdTNFα/Tgd: RTI 47.7 ± 21.1 vs. without RTI 24.7 ± 12.1, p = 0.0556). Here, ABCA1 is linked to leukemia.
