“…indeed, both occur in the immune-rich lymphoid tissues and are easily accessible to antibody-and cellbased immunotherapy (5). Moreover, CD30, a cell-membrane protein belonging to the tumor-necrosisfactor receptor superfamily 8, can be found on the cell-surface of both HL and selected NHL including ALCL, DLBCL, primary mediastinal B-cell lymphoma(6), peripheral T-cell lymphoma (7), and adult T-cell leukemia/lymphoma (8), as well as in rare solid tumors (9), including embryonal carcinomas (10) and seminomas (11). Its restricted expression on a subset of normal, activated T and B cells (12,13) renders CD30 an excellent candidate for immune-based therapies, with a low risk for off-tumor, ontarget toxicity.…”
