人类嗜T淋巴细胞病毒1型(HTLV-1)引起一系列慢性炎性疾病和称为成人T细胞白血病/淋巴瘤(ATLL)的T淋巴细胞的侵袭性恶性肿瘤。HTLV-1感染的主要特征是存在HTLV-1感染的T细胞的扩增克隆,其可持续数十年。高病毒负荷(前病毒负荷)与由HTLV-1引起的炎性和恶性疾病相关,并且已经认为感染细胞的寡克隆扩增易患这些疾病。然而,尚不清楚是什么调节HTLV-1在体内的克隆性,即HTLV-1感染的T细胞克隆的数量和丰度。我们回顾了HTLV-1感染和疾病的理解,来自高通量定量和分析HTLV-1的克隆性在自然感染的最新进展。
Human T lymphotropic virus type 1 (HTLV-1) causes a range of chronic inflammatory diseases and an aggressive malignancy of T lymphocytes known as adult T-cell leukaemia/lymphoma (ATLL). A cardinal feature of HTLV-1 infection is the presence of expanded clones of HTLV-1-infected T cells, which may persist for decades. A high viral burden (proviral load) is associated with both the inflammatory and malignant diseases caused by HTLV-1, and it has been believed that the oligoclonal expansion of infected cells predisposes to these diseases. However, it is not understood what regulates the clonality of HTLV-1 in vivo, that is, the number and abundance of HTLV-1-infected T cell clones. We review recent advances in the understanding of HTLV-1 infection and disease that have come from high-throughput quantification and analysis of HTLV-1 clonality in natural infection.
