限制异基因造血细胞移植(allo-HCT)的功效的两个主要并发症是疾病复发和移植物抗宿主病(GVHD)。由于其在allo-HCT后早期快速恢复以及在没有先前暴露的情况下杀死恶性靶标的能力,自然杀伤(NK)细胞被认为是介导早期移植物抗白血病(GVL)反应的主要效应细胞之一。相反,调节性T细胞(Treg)已被证明在促进自身耐受性方面至关重要。鼠和人的研究都证明了TcB在allo-HCT后GVHD的调节中的重要作用。在这里,我将审查这两种细胞类型如何执行这些功能的机制,重点放在后allo-HCT期间。令人惊讶的是,相对较少的研究已经解决了T细胞和NK细胞如何相互作用以及这些相互作用是否是拮抗性的。虽然临床前研究表明NK细胞和Treg之间存在活跃的串扰,但早期临床研究尚未显示Treg治疗对复发的不利影响。尽管如此,致耐受性信号的中断可增强NK效应子功能的功效。将讨论暂时损害Treg功能和增强NK细胞同种异体反应性的方法。
Two of the major complications that limit the efficacy of allogeneic hematopoietic cell transplantation (allo-HCT) are disease relapse and graft vs. host disease (GVHD). Due to their rapid recovery early after allo-HCT and ability to kill malignant targets without prior exposure, natural killer (NK) cells have been considered one of the main effector cells that mediate early graft vs. leukemia (GVL) reactions. Conversely, regulatory T cells (Treg) have proven to be critical in facilitating self-tolerance. Both murine and human studies demonstrate a significant role for Tregs in the modulation of GVHD after allo-HCT. Here I will review the mechanisms of how these two cell types carry out these functions, focusing on the post-allo-HCT period. Surprisingly, relatively few studies have addressed how Tregs and NK cells interact with one another and whether these interactions are antagonistic. While pre-clinical studies suggest active cross-talk between NK cells and Tregs, early clinical studies have not shown a detrimental impact of Treg therapy on relapse. Despite this, interruption of tolerogenic signals may enhance the efficacy of NK effector functions. Methods to transiently impair Treg functions and augment NK cell allo-reactivity will be discussed.
