From: Clinical implications of aberrant PD-1 expression for acute leukemia prognosis
Comparison of PD-1 expression in AL patients at the time of initial diagnosis and after achieving complete remission through effective therapy. A Changes in CD4+ PD1+ T lymphocytes in AML patients, n = 8, p = 0.0040. B Changes in CD8+ PD1+ T lymphocytes in AML patients, n = 8, p = 0.0173. C Changes in CD4+ PD1+ T lymphocytes in ALL patients, n = 4, p = 0.0165. D Changes in CD4+ PD1+ T lymphocytes in ALL patients, n = 4, p = 0.0806
