Definitive risk factors for the development of adult T-cell leukemia (ATL) among asymptomatic human T-cell leukemia virus type I (HTLV-1) carriers remain unclear. Recently, HTLV-1 proviral loads have been evaluated as important predictors of ATL, but a few small prospective studies have been conducted. We prospectively evaluated 1218 asymptomatic HTLV-1 carriers (426 males and 792 females) who ...
BACKGROUND In vitro studies support that integrase inhibitors, such as raltegravir, may inhibit human T cell lymphotropic virus type 1 (HTLV-1) replication. However, this hypothesis has not been tested in vivo. METHODS HTLV-1-infected individuals were invited to participate in a pilot, open study that examined whether 400 mg of raltegravir twice daily could exhibit any recognizable virologica...
The human T-lymphotropic virus (HTLV) proviral load remains the best surrogate marker for disease progression. Real-time PCR techniques have been developed for detection and quantification of cosmopolitan HTLV type 1a (HTLV-1a) and HTLV-2. Since a growing level of diversity in subtypes and genotypes is observed, we developed a multiplex quantitative PCR for simultaneous detection, genotyping, a...
human t-lymphotropic virus type i (htlv-1) is an endemic virus in iran and other regions that is associated with multiple diseases including adult t-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). ham/tsp is seen in approximately 2% of htlv-1-infected people with symptoms such as back pain, weakne...

Human T lymphocyte virus type I (HTLV-I)-associated chronic inflammatory neurological disease (HTLV-I-associated myelopathy/tropical spastic paraparesis [HAM/TSP]) is suggested to be an immunopathologically mediated disorder characterized by large numbers of HTLV-I Tax-specific CD8+ T cells. The frequency of these cells in the peripheral blood and cerebrospinal fluid is proportional to the amou...
which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Objective(s): HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the most common neurological manifestation of HTLV-I. The northeast of Iran is an endem-ic area for this virus. Host genetic and viral factors play important roles in developing HAM/TSP. T...
OBJECTIVE(S) HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV-I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated. MATERIALS AND METHODS ...
Peripheral blood mononuclear cells (PBMC) from three adult male squirrel monkeys (Saïmiri sciureus) were transformed by human T-cell leukemia/lymphoma virus type I (HTLV-I) by cocultivation with lethally irradiated human MT-2 cells. Three permanent monkey T-cell lines producing HTLV-I were obtained and characterized. Six weeks after inoculation seroconversion was observed in three of three monk...
It is thought that human T-cell lymphotropic virus type I (HTLV-I) preferentially infects CD41 T cells in vivo. However, observations of high HTLV-I proviral load in patients with HTLV-I–associated myelopathy/tropical spastic paraparesis suggest that HTLV-I may infect other cell types in addition to CD41 T cells. To identify in vivo T-cell tropisms of HTLV-I, real-time quantitative polymerase c...
