Compared with the low-risk group, the scores of macrophage (M0, M1, M2) Treg, tumor-associated fibroblasts, immunity, matrix, and microenvironment in the high-risk group were significantly higher, while in the low-risk group, neutrophils, memory CD4 + T cells, and T cell follicular helper cells were the main immune cell types (Figure 5(a)). The gene discussed is CD4; the disease is neoplasm.
