MICB and neoplasm: The most interesting of these, from a tumour immunology perspective, has been the natural killer group 2, member D (NKG2D) receptor, which can recognise MHC class I‐related proteins A and B (MICA and MICB), ectopically expressed antigens such as Rae1 or H60, as well as DNA damage‐induced cell surface ligands [139, 140], facilitating tumour cell elimination [140, 141, 142].
