代谢,包括分解代谢和合成代谢,是细胞生存所必需的基本细胞过程。T淋巴细胞具有独特的新陈代谢,可以决定命运和功能。T细胞的激活依赖于糖酵解来获得增殖和效应器功能所需的物质和能量。重要的是,T细胞在不同的条件和疾病下利用不同的代谢过程。异基因造血细胞移植(allo-HCT)是治疗恶性血液病的经典免疫疗法,然而移植物抗宿主病(GVHD)的发展是制约allo-HCT成功的主要因素。供者移植物中的T细胞通过对受体正常组织发动强大的免疫攻击来驱动移植物抗宿主病。因此,了解异基因造血干细胞移植后T细胞代谢将为控制移植物抗宿主病和原发肿瘤复发提供潜在的代谢靶点。本综述的目的是强调与同种异体抗原激活的T细胞有关的关键代谢途径,并讨论如何操纵这些途径作为潜在的新的治疗策略,以诱导异基因移植后的免疫耐受。我们还将总结在骨髓移植中通过靶向新的代谢调节或免疫检查点分子来调节T细胞代谢的最新进展。
Metabolism, including catabolism and anabolism, is a basic cellular process necessary for cell survival. T lymphocytes have a distinct metabolism that can determine both fate and function. T-cell activation depends on glycolysis to obtain materials and energy for proliferation and effector function. Importantly, T cells utilize different metabolic processes under different conditions and diseases. Allogeneic hematopoietic cell transplantation (allo-HCT) is a classic immunotherapy for hematological malignancies; however, the development of graft-versus-host disease (GVHD) is a major factor limiting the success of allo-HCT. T cells in the donor graft drive GVHD by mounting a robust immunological attack against recipient normal tissues. Hence, understanding T-cell metabolism after allo-HCT would provide potential metabolic targets for the control of GVHD and primary tumor relapse. The purpose of the current review is to highlight the key metabolic pathways involved in alloantigen-activated T cells and to discuss how manipulating these pathways can serve as potential new therapeutic strategies to induce immune tolerance after allo-transplantation. We will also summarize the recent progress in regulating T-cell metabolism in bone marrow transplantation by targeting novel metabolic regulators or immune checkpoint molecules.
