Applying pan-cancer TME signatures,53 non-NE TME was marked by immune infiltration including natural killer (NK) cells, B cells, and M1 tumor-associated macrophages (TAM-M1) and upregulation of immune co-activators (CD40LG, CD80) (Figure 3B) compared with hybrid-NE and NE TME.9 Here, CD80 is linked to neoplasm.
