RESUMEN
Acute Myeloid Leukemia (AML) is a complex disease with rapid progression and poor/unsatisfactory outcomes. In the past few years, the focus has been on developing newer therapies for AML; however, relapse remains a significant problem. Natural Killer cells have strong anti-tumor potential against AML. This NK-mediated cytotoxicity is often restricted by cellular defects caused by disease-associated mechanisms, which can lead to disease progression. A stark feature of AML is the low/no expression of the cognate HLA ligands for the activating KIR receptors, due to which these tumor cells evade NK-mediated lysis. Recently, different Natural Killer cell therapies have been implicated in treating AML, such as the adoptive NK cell transfer, Chimeric antigen receptor-modified NK (CAR-NK) cell therapy, antibodies, cytokine, and drug treatment. However, the data available is scarce, and the outcomes vary between different transplant settings and different types of leukemia. Moreover, remission achieved by some of these therapies is only for a short time. In this mini-review, we will discuss the role of NK cell defects in AML progression, particularly the expression of different cell surface markers, the available NK cell therapies, and the results from various preclinical and clinical trials.

Relationship between various combinations of KIR ligands and HLA alleles have been studied in several diseases. The aim of this retrospective study was to estimate the frequency of HLA alleles and KIR ligands among acute myeloid leukemia patients and healthy controls in order to examine the possible association of HLA alleles and KIR ligands with AML. A total of 439 acute myeloid leukemia patients and 1317 unrelated, healthy ethnic Indian controls were included in the study. HLA typing was performed using PCR-SSP. KIR ligands were assigned by using the KIR ligand Calculator. The frequency of HLA alleles and KIR ligands in patients was then compared with the controls. As compared to controls, frequencies of HLA-A*03 and HLA-B*35 were increased in AML patients, whereas, that of HLA-C*03 was decreased. Frequencies of HLA-A*03 and HLA-C*15 were increased in male patients, however, no significant difference was observed in female patients as compared to controls. In the pediatric group, the frequencies of HLA-A*01 was decreased and that of HLA-A*03 and HLA-B*18 were increased, whereas, frequencies of HLA-B*13 was decreased and that of HLA-B*27 was increased in the adult patients. In the haplotype analysis, the frequency of HLA-A*24/B*35/DRB1*15 was increased in overall patients. In adult group, the frequency of HLA-A*01/B*44/DRB1*07 was increased in patients than in controls. No significant association was observed between KIR ligands and susceptibility/ protection to AML. Our results indicate that certain HLA alleles and haplotypes have presumptive positive or negative role in conferring protection/susceptibility to AML.
