To investigate whether the KLRB1‐driven exhaustion program is present in CD8+ TRM across other hematologic malignancies, we analyzed published scRNA‐seq datasets from patients with acute myeloid leukemia (AML), diffuse large B‐cell lymphoma (DLBCL), follicular lymphoma (FL), mantle cell lymphoma (MCL), Hodgkin lymphoma (HL) (Figure S7A, Supporting Information). This evidence concerns the gene KLRB1 and acute myeloid leukemia.
