BCR-ABL1 tyrosine kinase inhibitors (TKIs) have dramatically improved the long-term outcomes of patients with chronic myelogenous leukemia (CML). Notably, approximately half of patients with a sustained deep molecular response experienced treatment free remission (TFR) even after discontinuation of TKI. Although antitumor immunity by natural killer (NK) cells might contribute to the effects of TKI and TFR in CML, the details of their actions have not as yet been elucidated. Recently, several reports have raised the possibility that the killer immunoglobulin-like receptor (KIR), a highly polymorphic NK cell receptor, may play important roles, because polymorphic patterns of KIR were shown to be associated with the intensity of clinical responses and outcomes in TKI-treated CML patients. Herein, we summarize genetic and immunological aspects of KIR, and also discuss the association between KIR and CML. If KIR polymorphism is actually associated with the outcomes of TKI-treated CML patients, we might be able to obtain prognostic information for patients and assess the possibility of TFR, which would not only benefit patients, but also provide a platform for improving the outcomes of other hematologic malignancies utilizing NK cell immunity.

UI	MeSH Term	Description	Entries
D007694	Killer Cells, Natural	Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D015464	Leukemia, Myelogenous, Chronic, BCR-ABL Positive	Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.

D054340	Receptors, KIR	A family of receptors found on NK CELLS that have specificity for a variety of HLA ANTIGENS. KIR receptors contain up to three different extracellular immunoglobulin-like domains referred to as D0, D1, and D2 and play an important role in blocking NK cell activation against cells expressing the appropriate HLA antigens thus preventing cell lysis. Although they are often referred to as being inhibitory receptors, a subset of KIR receptors may also play an activating role in NK cells.
