The results showed a close association between risk score and CSF1R of monocytes, CCL2 of tumor-associated macrophages, CD163, VSIG4, and MS4A4A of M2 macrophages, ITGAM and CEACAM8 of neutrophils, KIR2DL3 and KIR3DL2 of natural killer cells, and HLA-DPB1, HLA-DRA, HLA-DPA1, and NRP1 of dendritic cells (Figure 5B), as well as closed associated with immune checkpoint markers such as NRP1, LAIR1, and TNFSF4 (Figure 5C). The gene discussed is HLA-DRA; the disease is neoplasm.
