WT1 and leukemia: Frequencies of adaptive and innate/antigen-/leukemia-specific immune cells (e.g., degTnon-naïve/Tnon-naïve, degTcm/Tcm, degCIK/CIK) were increased (or decreased: degTCD4+reg/TCD4+reg) after the addition of leukemia-specific (WT1, PRAME) to AML or Staphylococcal Enterotoxin B (SEB) antigens to healthy donors’ samples, as shown previously [18,25] (Supplementary Figure S2A,B).
