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)). Here, CD8A is linked to neoplasm.
