摘    要:
目前,异基因造血干细胞移植(allo-HSCT)已广泛应用于造血系统疾病的治疗,但移植术后也存在一系列并发症。NK细胞的运用为改善allo-HSCT受者预后带来希望,供者来源NK细胞通过其细胞膜上的杀伤细胞免疫球蛋白样受体与其配体错配发挥同种异体反应,该过程具有保留移植物抗白血病和减少移植物抗宿主病双重效应。NK细胞是allo-HSCT后受者体内最早重建的免疫细胞群,因此移植后供、受者NK细胞嵌合状态评估对预测疾病预后及指导干预治疗具有重要意义。基于NK细胞嵌合状态的供者NK细胞输注免疫干预疗法可改善疾病预后,在血液系统疾病治疗中表现出良好的应用前景。本文就近年来供者NK细胞及其嵌合状态在allo-HSCT中的研究进展作一综述。

关 键 词:异基因造血干细胞移植  NK细胞  同种异体反应  嵌合状态  移植物抗宿主病  移植物排斥反应

Abstract:
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been widely used for the treatment of hematopoietic diseases, nonetheless, major challenges persist, including a series of complications. The application of natural killer (NK) cells brings hope for improving the prognosis of patients after allo-HSCT. Killer cell immunoglobulin-like receptors (KIR) located on cytomembrane of donor NK cells and KIR-ligands mismatch plays a role in promoting the alloreactivity of NK cells, which maintains graft versus leukemia effects while reducing graft versus host disease. NK cells is the first immune cell subset to recover after allo-HSCT, so the monitoring of NK cells chimerism plays an significant role in predicting the prognosis of diseases and the intervention treatment. Furthermore, NK cells infusion based on chimerism is likely to improve the prognosis, which shows a broad application prospect in hematopoietic diseases. This article is to review the research progress of aforementioned aspects.
Keywords:Allogeneic hematopoietic stem cell transplantation  Natural killer cell  Alloreactivity  Chimerism  Graft versus host disease  Graft rejection
