Genetic and clinical evidence supports HLA-DR+ CD8+ T cells as a favorable immune biomarker in acute myeloid leukemia.
Immune dysregulation is central to acute myeloid leukemia (AML), but the contribution of specific immune subsets remains uncertain. We combined Mendelian randomization (MR), clinical flow cytometry, and transcriptomic profiling to investigate HLA-DR+ CD8+ T cells in AML. Two-sample MR using 731 immunophenotypes and AML...
