虽然人类T细胞白血病病毒1型(HTLV-1)是成人T细胞白血病/淋巴瘤(ATL)的病原体,但迄今为止,其近亲HTLV-2与ATL或其他类型的恶性肿瘤无关。越来越多的证据表明,HTLV-1 Tax1和HTLV-2 Tax2具有许多共同的活性,但这两种蛋白具有有限数量的显著不同的活性,这些差异似乎在HTLV-1特异性发病机制中起关键作用。本文就Tax1在细胞存活、细胞增殖、持续感染以及致病机制中的作用进行综述。我们强调特别注意Tax1和Tax2之间的区别。
While the human T-cell leukemia virus type 1 (HTLV-1) is the etiologic agent of adult T-cell leukemia/lymphoma (ATL), to date, its close relative HTLV-2 is not associated with ATL or other types of malignancies. Accumulating evidence shows that HTLV-1 Tax1 and HTLV-2 Tax2 have many shared activities, but the two proteins have a limited number of significantly distinct activities, and these distinctions appear to play key roles in HTLV-1 specific pathogenesis. In this review, we summarize the functions of Tax1 associated with cell survival, cell proliferation, persistent infection as well as pathogenesis. We emphasize special attention to distinctions between Tax1 and Tax2.
