Several plasma cell-specific antigens at the surface of myeloma cells have been studied as targets for TCEs, including B-cell maturation antigen (BCMA), G protein-coupled receptor, class C group 5 member D (GPRC5D), and Fc receptor-homolog 5 (FcRH5) [7,8,9,10,11]. This evidence concerns the gene TNFRSF17 and plasma cell myeloma.
