Low expression of IL‐11 in tumour cells was associated with significantly higher levels of leukocytes (CD45), T cells (CD3, CD4, CD8), T‐cell activation (CD44, CD25, ICOS, Tim3), dendritic cell activation, antigen presentation (CD11c, CD80, B2M, HLA‐DR) and macrophage (CD68) markers (Figure 6F). Here, HAVCR2 is linked to neoplasm.
