Vδ1 T cells recognize MHC class I-related molecule A (MICA), MHC class I-related molecule B (MICB), and UL16-binding proteins (ULBPs) molecules, a group of proteins expressed on stressed and tumor cells (10, 11), and the MHC-related class Ib molecules CD1c and CD1d, which are typically involved in glycolipid presentation (12, 13). The gene discussed is MICB; the disease is neoplasm.
