The immune cell content in the samples was shown in Fig. 5A. It was depicted that B cells naïve, T cells CD4 memory resting, Macrophages M0, M1, M2 were higher in tumor cells, while B cells memory, plasma cells, T cells CD8, T cells CD4 memory activated and Monocytes were lower in tumor cells (Fig. 5B). The gene discussed is CD8A; the disease is neoplasm.
