Besides TCR-associated antigen recognition, Vγ9Vδ2 T cells also express NK receptors including NKG2D and DNAM1, which recognize MHC class I chain-related molecules (MICA, MICB), ULBP-binding proteins (ULBPs) and Nectin-like-5 that are broadly expressed on tumor cells (4). This evidence concerns the gene MICA and neoplasm.
