Analysis shows CD39+ T cells are linked to T cell exhaustion and worse outcomes in AML, suggesting a potential immunotherapeutic target.

To investigate the clinical relevance of CD39 expression on T cell subsets in acute myeloid leukemia (AML).
Analyzed CD39 expression using multiparametric flow cytometry in AML patients' bone marrow T cells.
Utilized t-SNE visualization for T cell subset clustering.
Performed bulk RNA sequencing on sorted CD39+ and CD39- CD8+ T cells.
Conducted gene set enrichment analysis to examine pathways associated with T cell exhaustion.
Higher frequencies of CD39+ T cells in AML patients correlated with lower complete response rates.
Increased CD39+ T cells associated with inferior event-free survival.
Gene set enrichment analysis revealed upregulation of exhaustion markers in CD39+ T cells.
