In addition, the generated heatmap showed that 11 immune cell subtypes, M1 macrophages, CD8 T cells, M0 macrophages, M2 macrophages, resting CD4 memory T cells, memory B cell, naïve B cells, and regulatory T cells (Treg), monocytes, resting myeloid dendritic cells, and activated mast cells presented significant different proportions between the tumor group and the normal group (Figure 4(b)). The gene discussed is CD4; the disease is neoplasm.
