CD4 and chronic myelogenous leukemia, BCR-ABL1 positive: Immune infiltration analysis showed that CML samples had fewer naive and memory B cells, plasma cells, CD8+ T cells, naive CD4+ T cells, activated memory CD4+ T cells, resting NK cells, and activated dendritic cells, and contained more regulatory T cells (Tregs) than normal samples (Figure 2C), which confirm the immunosuppressive features evident in CML samples.
