中文摘要
摘要:
人类T细胞白血病病毒(HTLV-1)在全球范围内感染了约1500万至2000万人,是其病因之一。
作为成人T细胞白血病/淋巴瘤患者(ATLL)的代理人,他们也可能导致一种炎症性疾病和综合征。
被称为HTLV-1相关的脊髓病(HAM)/热带痉挛性截瘫(TSP)。
不同地区的抗体患病率不同,成年人的抗体患病率从0.2%到10%不等。这意味着抗体的流行率。
随着年龄、年龄和年龄的增加,年龄增加也会影响多达20%到50%的60岁及以上女性人口。
中国人臭名昭著,因为在细胞培养中很难研究这些问题,这也禁止了对这些问题进行更严格的科学分析。
病毒可以在细胞中复制病毒,包括逆转录病毒组装过程中涉及的步骤。以下是逆转录病毒如何作用的更多细节。

人类免疫缺陷病毒1型(HIV-1)。例如,最近的一项研究证据表明,人类免疫缺陷病毒是一种恶作剧。
不同的逆转录病毒之间的相互作用可能有所不同,这有助于解释我们还没有记录的形态上的差异。

英文摘要
Abstract
Human T-cell leukemia virus (HTLV-1) infects about 15-20 million individuals worldwide and is the etiological
agent of an adult T-cell leukemia/lymphoma (ATLL), and can also result in an inflammatory disease syndrome
called HTLV-1-associated myelopathy (HAM)/tropical spastic paraparesis (TSP). HTLV-1 antibody prevalence
rates vary among geographical areas, ranging from 0.2 to 10% among adults. This antibody prevalence
increases with age, and can affect as much as 20 to 50% of the female population aged 60 and above. HTLV-1
is notorious for being difficult to study in cell culture, which has prohibited a rigorous analysis of how these
viruses replicate in cells, including the steps involved in retrovirus assembly. The details for how retrovirus
particle assembly occurs are poorly understood even for other more tractable retroviral systems like that of
human immunodeficiency virus type 1 (HIV-1). For instance, recent evidence indicates that Gag-Gag
interactions differ among retroviruses, which helps explain morphological differences that we have documented
among immature retrovirus particles. Furthermore, the role for membrane-bound, non-punctate (np) Gag in the
biogenesis of Gag puncta, as well as the nature of Gag puncta biogenesis in the context of cell-to-cell contacts
also remain poorly understood aspects of the retrovirus assembly pathway. This is particularly for HTLV-1, for
which we have found to have fundamentally distinct differences to that of HIV-1 regarding the role of
membrane-bound np Gag in Gag punta biogenesis. In this application, we propose to continue our
investigations on HTLV-1 immature and mature particle structure and particle biogenesis through innovative
state-of-the-art experimental approaches with appropriate comparative analyses with HIV-1. In particular, we
will apply cryo-electron microscopy/tomography (cryo-EM/ET), photoactivated localization microscopy (PALM),
total internal reflection fluorescence (TIRF) microscopy and the novel technology of z-scan fluorescence
fluctuation spectroscopy (FFS) in living cells to investigate 1) analysis of immature HTLV-1 Gag lattice
structure, 2) the importance of membrane-bound, np Gag in HTLV-1 particle biogenesis, and 3) HTLV-1
particle biogenesis in the context of cell-cell contacts. Careful comparisons will be done with HIV-1. These
novel studies harness innovative technologies in order to provide new insights into a highly significant and
poorly understood aspect of the HTLV-1 particle assembly process, which is fundamentally distinct from that of
HIV-1 and other retroviruses. Furthermore, our studies represent some of the most detailed studies conducted
on the assembly of virus structural proteins, which provides fundamentally important information in virology on
the molecular nature of virus particle assembly at the plasma membrane for enveloped viruses.
