Twenty human T-lymphotropic virus type I (HTLV-I) antibody-positive sera from Japan, Hawaii, and the Marshall Islands and 15 HTLV type II (HTLV-II) antibody-positive sera from intravenous drug users in the United States were tested by immunoblotting with two recombinant HTLV-I proteins and three commercial kits to determine whether there were any differences in reactions between HTLV-I- and HTL...
Short or damaged telomeres have been implicated in degenerative conditions. We hypothesized that analysis of telomere length (TL) in human T-cell lymphotropic virus (HTLV) infection and HTLV-associated neuropathy might provide clues to the etiology of HTLV-associated disease and viral dynamics. A subset of 45 human T-cell lymphotropic virus type 1 (HTLV-1), 45 human T-cell lymphotropic virus ty...
Human T cell leukemia/lymphoma virus Type 1 and 2 (HTLV-1 and HTLV-2), together with their simian counterparts (STLV-1, STLV-2), belong to the Primate T lymphotropic viruses group (PTLV). The high percentage of homologies between HTLV-1 and STLV-1 strains, led to the demonstration that most HTLV-1 subtypes arose from interspecies transmission between monkeys and humans. STLV-3 viruses belong to...
Viral cell-free DNA (cfDNA) in plasma has been widely evaluated for detecting cancer and monitoring disease virus-associated tumors. We investigated whether the amount of cfDNA human T-cell leukemia virus type 1 (HTLV-1) correlates with state adult leukemia-lymphoma (ATL). HTLV-1 aggressive ATL was significantly higher than that indolent asymptomatic carriers. Notably, patients lymphoma represe...
Human T-cell leukemia virus types I (HTLV-I) and II (HTLV-II) are human retroviruses which normally infect T-lymphoid cells. HTLV-I infection is associated with adult T-cell leukemia-lymphoma, and HTLV-II is associated with an indolent form of hairy-cell leukemia. To identify potential transcriptional regulatory elements of these two related human retroviruses, we performed DNase I footprinting...
BACKGROUND Human T lymphotropic virus types 1 (HTLV-1) and 2 (HTLV-2) are frequent copathogens among individuals infected with human immunodeficiency virus type 1 (HIV-1). The long-term effects of coinfection are unknown, and little information exists regarding how levels of HTLV-1/2 viral burden are affected by antiretroviral medications. METHODS Factors associated with HTLV-1/2 viral burden...
مقدمه: شمال شرقی ایران، به ویژه شهر مشهد، از نواحی اندمیک ویروس لنفوتروپیک سلول های t انسانی نوع 1 (htlv-i یا human t-cell lymphotropic virus type 1) می باشد؛ اما در مورد شیوع نوع 2 ویروس (htlv-ii) در این منطقه، اطلاعات کافی موجود نیست. این مطالعه ی مقطعی با هدف تعیین شیوع عفونت htlv-ii در جمعیت عمومی مشهد صورت گرفت. روش ها: 1678 نفر از جمعیت عمومی شهر مشهد با روش نمونه گیری خوشه ای چندمرحله ای...
The current env-based subtyping of human T-cell lymphotropic virus type II (HTLV-II) identifies only two heterogenetic groups, HTLV-IIa and HTLV-IIb. To better understand the genetic diversity and phylogeny of HTLV-II, we examined the most divergent genomic region of HTLV-II, the long terminal repeat, by using restriction fragment length polymorphism (RFLP) and sequence analysis. Long terminal ...
Pseudotypes of vesicular stomatitis virus (VSV) bearing envelope antigens of human T-cell leukemia virus (HTLV) types 1 and 2 were prepared by propagating VSV in cells lines productively infected with HTLV. Plaque assays of VSV (HTLV) pseudotypes were employed to determine the presence of (i) HTLV receptors on cells and (ii) neutralizing antibodies in the serum of patients with adult T-cell leu...
Background: A study was undertaken to investigate the pathogenesis of pulmonary involvement in human T lymphotropic virus type I (HTLV-I) carriers. Methods: The bronchoalveolar lavage (BAL) cell profile of 30 HTLV-I carriers (15 asymptomatic HTLV-I carriers (AHCs) and 15 symptomatic HTLV-I carriers (SHCs)) with chronic inflammatory diseases of respiratory tract and eight patients with HTLV-I as...
