T-lymphocytes (CTLs). Recent studies have demonstrated that immunoproteasome activation increases the presentation of tumor-specific neo-antigens, thereby offering a potential strategy to improve the antimyeloma effects of T-cell-mediated immunotherapies. Here, we discuss advantages and strategies that support the administration of TCR-engineered T-cells for the treatment of MM. This review focuses on the role of immunoproteasome dependent antigen processing in shaping the myeloma immunopeptidome and enabling TCR-based immunotherapy. We discuss how modulation of neoantigen presentation may inform the design of TCR-engineered T cells and related immunotherapeutic strategies for MM.
