Özet
High expression of immune checkpoint markers may leukemic cells to evade the immune system in AML. This study aimed to investigate the relationship between PD-1/PD-L1 expression and treatment outcomes in AML patients. The study included 21 patients and 18 healthy volunteers. Non-responders exhibited significantly higher PD-1 expression (MFI) in CD3+ and CD4+ T cells. At the time of diagnosis, bone marrow samples from patients exhibited a significantly higher proportion of PD-1 expression in CD3+, CD4+, and CD8+ T lymphocytes than peripheral blood samples. The results revealed an association between PD-1/PD-L1 expression and clinical traits in newly diagnosed AML patients.
