By immune infiltration analysis, we observed that some anti-tumor immune cells, like Tfh cells, gamma delta T cells, M1 macrophages, and activated dendritic cells, were strongly enriched in the low-risk subgroup, whereas tumor-promoting cells, such as M2 macrophages and resting CD4 memory T cells, were more prevalent in the high-risk subgroup. The gene discussed is CD4; the disease is neoplasm.
