An additional study reported lower response frequency in comparison to chronic myeloid leukaemia patients (42) and another detected T cell responses (> 30 IFN-γ releasing cells/105 cells), but failed to dissect the relative contribution of the CD4+ and CD8+ T cell subsets (24). The gene discussed is CD8A; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
