The different immunocyte proportions between CRC and adjacent normal tissues are depicted in Figure 2A. The immunocyte fractions in the different subgroups of CRC patients are provided in Figure 2B. Generally speaking, the five most common immunocyte subtypes in CRC patients were M0 macrophages, CD8+ T cells, M1 macrophages, resting memory CD4+ T cells, and M2 macrophages. The gene discussed is CD8A; the disease is colorectal carcinoma.
