In addition, the infiltrating results of myeloid-derived suppressor cells (MDSCs) and the M2 subtype of tumor-associated macrophages (TAM.M2) and the expression of interferon-γ (IFNG) were significantly different between the different risk subgroups (Supplementary Table S3) and correlated with the risk score (Figure 6B). The gene discussed is IFNG; the disease is neoplasm.
