BCMA antibodies, able to induce antibody-dependent cell-mediated cytotoxicity (ADCC) mediated lysis in BCMA expressing cells, were identified in the serum of allotransplanted MM patients after donor lymphocyte infusion, thus demonstrating the role of BCMA as target for graft versus tumor response [35]. The gene discussed is TNFRSF17; the disease is neoplasm.
