The abundant combination between <i>KIR</i> and <i>HLA</i> through genetic polymorphisms determines the functional diversity of NK cells. We previously reported that <i>KIR3DL1-HLA-Bw</i> status is associated with achievement of TFR by reflecting NK cell potential. Patients with strong interaction between <i>KIR3DL1/HLA-Bw</i> were identified as having a higher molecular relapse risk, based on the “missing self” hypothesis which suggests that the lack of cognate ligands for KIRs may induce target cell lysis. However, all the patients with strong interaction between <i>KIR3DL1/HLA-Bw</i> who received prior IFN-α therapy achieved TFR (<i>p</i> = 0.007), explained by the “NK cell licensing” concept, whereby NK cells become more functional through the recognition “self” HLA class I molecules by KIRs. NK cell licensing may contribute to the potential efficacy of IFN-α treatment in patients with CML. We defined high-risk molecular relapse patients and suggest that <i>KIR3DL1/HLA-Bw</i> status may help detect patients who could benefit from IFN-α for maintaining TFR.</p>","PeriodicalId":72883,"journal":{"name":"EJHaem","volume":"5 6","pages":"1278-1282"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11647684/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
