摘要

Background and Aims. Natural killer (NK) cells are innate immune system cells that are actively involved in immune-surveillance of tumor cells. Recognition of tumors by NK cells occurred via natural cytotoxicity receptors and killer cell immunoglobulin-like receptors. Some ligands of the activating receptors seem to be present on malignant cells from patients with acute myeloid leukemia. The aim of the study was to evaluate the expression of activating receptors such as NKG2D, DNAM-1, NKp30, and NKp46, and inhibitory receptors such as NKG2A, CD158b, CD158a, and CD158e1 on NK cells from patients with newly diagnosed acute myeloid leukemia before and after stimulation with IL-2 and IL-12.
