the underlying mechanisms leading to the development of human t-cell lymphotropic virus type i (htlv-i) associated myelopathy/tropical spastic paraparesis (ham/tsp) in htlv-i infected individuals are not fully understood. host genetic factors appear to be involved as risk factors for developing ham/tsp. we investigated the possible contribution of interleukin-10 (il-10) as a risk factor to ham/...
Synthetic peptides of 20-25 amino acids were employed in enzyme-linked immunosorbent assays to identify linear epitopes in the external glycoprotein gp46 and the transmembrane glycoprotein gp21 of human T-cell leukemia/lymphotropic viruses type I (HTLV-I) and II (HTLV-II). Ten linear epitopes were identified in the HTLV-I glycoproteins, seven in gp46 and three in gp21. Three major linear epitop...
To investigate candidate genes that influence the risk of HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP), we analyzed 6 single nucleotide polymorphisms (SNP) in the interleukin-10 (IL-10) promoter region. METHODS: 280 cases of HAM/TSP patients and 255 HTLV-I seropositive asymptomatic carriers (HCs) from Kagoshima, Japan were studied. All subjects gave written informed conse...

Introduction: To recognize the predisposing factors in tuberculosis as an endemic infection in Northeast province of Iran, this study was aimed to evaluate whether HumanT-lymphocyte type 1 (HTLV-I) as an immunosuppressive factor increases the risk of tuberculosis. Materials and Methods: A Case-control study was conducted in 278 tuberculosis patients from 2007 to 2010, in Mashhad, Iran. Tubercul...
Human T-lymphotropic virus type I (HTLV-I) infects an estimated 15-20 million persons worldwide. A number of diseases have been associated with the virus including adult T-cell leukemia (ATL), HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP), HTLV-I uveitis, and HTLV-I-associated infective dermatitis. Once it was shown that there is an increased risk for developing HAM/TSP asso...
We describe the use of an immunofluorescence assay and coculture to confirm human T-cell leukemia-lymphoma virus (HTLV) infection. Peripheral blood mononuclear cells from 32 of 32 seropositive donors were positive in the immunofluorescence assay, and 63% of their cocultures produced p24 antigen. Specific antibodies distinguished HTLV type I (HTLV-I) from HTLV-II. HTLV-I or HTLV-II was isolated ...
Infection with human immunodeficiency virus type 1 (HIV-1) or T-lymphotropic I (HTLV-I) both can lead to mortality. CD4+T cells are the target for HTLV-I and HIV-1. In addition, HIV-1 infect macrophages. macrophages play important roles in immune system response. This article develops analyzes a discrete-time co-infection model. The model depicts within-host interaction of six compartments: uni...
Human T-cell leukemia virus type I (HTLV-I) is the etiologic agent for adult T-cell leukemia and the neurological disorder tropical spastic paraparesis/HTLV-I-associated myelopathy. CD4+ T lymphocytes, the primary hosts for HTLV-I, undergo a series of changes that lead to T-cell activation, immortalization, and transformation. To gain insight into the genetic differences between activated and H...
background and aims: human t-lymphotropic virus (htlv) is a human retrovirus which has been known to cause adult t-cell leukemia/lymphoma and some other inflammatory disorders. patients with hereditary bleeding diseases are at high risk for these viruses. in this study, we evaluated serological htlv-i/ii infection among these patients in west azerbaijan of iran. material and methods: we studied...
