This research identifies a specialized group of tumor-reactive T cells within the bone marrow of patients with multiple myeloma (MM) and acute myeloid leukemia (AML). Unlike the exhausted cells typically found in solid tumors, these bone marrow lymphocytes exist in a latent effector state that remains functionally capable of being activated by immunotherapy. The authors discovered that these immune responses are often driven by noncanonical antigens and shared genetic vulnerabilities across both diseases rather than traditional mutations. To better identify these cells, the team developed…
