HLA-A and acute myeloid leukemia: Following co-culture with AML blasts harvested post-decitabine, we observed an increase in the levels of IFN-γ, TNF-α, IL-2, and CD107a/b in HLA-A*0201/NY-ESO-1157-165 tetramer+ CD8+ T-cells in three of four patients studied, compared to T-cells co-cultured with AML blasts obtained prior to decitabine exposure (Figure 6B and 6D).
