逆转录病毒诱导的恶性肿瘤可以作为理想的模型,帮助我们更好地理解与白血病发生的起始和进展相关的分子机制。包括AEV、FLV、M-MuLV和HTLV-1在内的许多逆转录病毒具有感染造血干细胞和祖细胞的能力,导致正常造血功能的失调和白血病/淋巴瘤的发展。过去几十年的研究已经阐明了逆转录病毒诱导的白血病发生与癌症干细胞假说之间的相似之处,逆转录病毒诱导的白血病发生是由先天造血干细胞特性的解除引起的。在这些模型中,一些正在进行的研究可能会更好地理解正常造血和癌症干细胞的过程。对逆转录病毒诱导的白血病和淋巴瘤的研究可能会确定触发血液恶性肿瘤的初始细胞转化和随后维持的分子事件,包括癌症干细胞的产生。本文综述了逆转录病毒感染在造血干细胞中的作用以及血液系统恶性肿瘤的发生、维持和发展。
Retroviral induced malignancies serve as ideal models to help us better understand the molecular mechanisms associated with the initiation and progression of leukemogenesis. Numerous retroviruses including AEV, FLV, M-MuLV and HTLV-1 have the ability to infect hematopoietic stem and progenitor cells, resulting in the deregulation of normal hematopoiesis and the development of leukemia/lymphoma. Research over the last few decades has elucidated similarities between retroviral-induced leukemogenesis, initiated by deregulation of innate hematopoietic stem cell traits, and the cancer stem cell hypothesis. Ongoing research in some of these models may provide a better understanding of the processes of normal hematopoiesis and cancer stem cells. Research on retroviral induced leukemias and lymphomas may identify the molecular events which trigger the initial cellular transformation and subsequent maintenance of hematologic malignancies, including the generation of cancer stem cells. This review focuses on the role of retroviral infection in hematopoietic stem cells and the initiation, maintenance and progression of hematological malignancies.
