These steps include membrane and intercellular signalling proteins involved in T‐cell and NK cell activation (CD1C, CD1E, NKAP), recruitment (CCR6, XCL1), tumour recognition (CD1C, CD1E, HLAA, HLAB, HLAH) and CD8 T‐cell differentiation (EOMES).35, 36. This evidence concerns the gene HLA-H and neoplasm.
