摘要:

文题释义:
造血干细胞移植:是指患者进行化疗、全身放疗和免疫抑制剂预处理后,将供者来源造血干细胞或自体造血细胞移植入患者体内,使之进行造血重建,建立正常的造血和免疫功能。
免疫重建:是指免疫缺陷病患者通过移植正常供者的免疫器官或组织,使患者恢复免疫功能。

背景:异基因造血干细胞移植是治愈白血病等恶性血液病、重症再生障碍性贫血和遗传性血液病的最有效方法,但移植后早期常因免疫重建延迟,显著增加巨细胞病毒感染/再激活的风险。只有促进早期免疫重建,才能激发机体产生巨细胞病毒特异性免疫应答,真正有效的长期控制病毒复制。
目的:总结间充质干细胞移植后免疫重建和抗巨细胞病毒免疫作用的研究进展,并分析目前面临的问题及其未来发展方向。
方法:以“allogeneic hematopoietic stem cell transplantation,mesenchymal stem cells,immune reconstruction,CMV”为关键词检索PubMed数据库,检索时限为2016-2020年,排除与文章研究目的无关及重复性文章,纳入符合标准的46篇文献进行综述。
结果与结论:胸腺功能的恢复有利于促进T细胞应答库多样性的恢复,是免疫重建和抗病毒治疗优化的关键。免疫学最新进展表明,间充质干细胞可能具有逆转胸腺衰老、修复胸腺损伤和促进胸腺再生的功能,并通过多靶点和多重机制发挥抗病毒效应并保护宿主免受病毒攻击,但仍然存在许多局限性,miR-21基因修饰间充质干细胞有望为移植后免疫重建和抗病毒免疫提供新思路和新策略,这些将是未来细胞疗法需要努力的方向。

Abstract: BACKGROUND: Allogeneic hematopoietic stem cell transplantation is the most effective method to cure leukemia and other malignant hematological diseases, severe aplastic anemia, and hereditary hematological diseases. However, immune reconstitution is often delayed in the early stage after transplantation, which significantly increases the risk of cytomegalovirus infection/reactivation. Only promoting early immune reconstitution can produce a cytomegalovirus-specific immune response and truly and effectively control virus replication for a long time. 
OBJECTIVE: To summarize the research progress of immune reconstruction and anti-cytomegalovirus immune function of mesenchymal stem cells after transplantation, and analyze the current problems and future development directions. 
METHODS: The PubMed database was searched with “allogeneic hematopoietic stem cell transplantation, mesenchymal stem cells, immune reconstruction, CMV” as key words. The search time limit was from 2016 to 2020. Repetitive articles irrelevant to the research purpose of the article were excluded, and 46 articles that met the criteria were included for review. 
RESULTS AND CONCLUSION: The restoration of thymus function is beneficial to promote the restoration of the diversity of T cell response pools, and is the key to immune reconstitution and antiviral therapy optimization. The latest progress of immunology indicates that mesenchymal stem cells may have the functions of reversing thymic aging, repairing thymus damage and promoting thymus regeneration, and exert antiviral effects through multiple targets and multiple mechanisms and protect the host from virus attack. However, there are still many limitations. The miR-21 genetically modified mesenchymal stem cells are expected to provide new ideas and new strategies for immune reconstruction and anti-viral immunity after transplantation. These will be the direction of future cell therapy. 

Key words: stem cells, mesenchymal stem cells, allogeneic hematopoietic stem cell transplantation, immune reconstruction, anti-cytomegalovirus immunity, gene, review
