CD86 and neoplasm: In this study, we demonstrated that SQLE had the most significant correlations with tumor‐infiltrating lymphocytes (such as Mast, Monocyte, MDSC, and Act_DC), immunostimulators (such as TNFSF13, CD86, C10orf54, and CD48), immunoinhibitors (such as IL10, CD244, HAVCR2, and PDCD1LG2), and MHC molecules (such as HLA–DMB, HLA–DRA, HLA–DMA, and HLA–DOA).
