Human T lymphotropic virus type I (HTLV-I) is a retrovirus which is associated with adult T cells leukaemia (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in a minority of HTLV-I-infected individuals. It is not clear why a minority of HTLV-I-infected individuals develop HAM/TSP and majority remains lifelong carriers. It seems that the interaction between the v...
Objective(s): Coronary artery disease (CAD) is known as a life threatening disease, worldwide. In this study the role of HTLV-1 infection was evaluated on cardiac involvement in an endemic region of northeastern Iran.Materials and Methods: Serologic and molecular tests for HTLV-1 infection were carried out in subjects who had coronary an...
An immunodominant HTLV-I-specific epitope in the HTLV-I envelope glycoprotein (GP) 46 has been described. To determine if the analogous region of HTLV-II contains a similarly immunogenic and specific epitope, the polymerase chain reaction (PCR) was used to amplify HTLV-II DNA fragments encoding various portions of the putative epitope. The synthesized DNAs were cloned into lambda-phage gt11 and...
Screening of blood for human T-cell lymphotropic virus type 1 and type 2 (HTLV-1 and -2, respectively) is important to diagnose and prevent infection and ensure the safety of blood supplies. The Elecsys HTLV-I/II assay is a newly developed, electrochemiluminescence screening assay for the detection of HTLV-1/2 infection. The sensitivity and specificity of the Elecsys HTLV-I/II assay were determ...
زمینه و هدف: ویروس لنفوتروپیک سلولT انسانی (HTLV-I) عامل دو بیماری مهم لوسمی ـ لنفومای سلول T بالغین و بیماری پاراپارزی اسپاستیک تروپیکال ـ میلوپاتی همراه با HTLV-I یا HAM/TSP میباشد. یکی از راههای انتقال آن تزریق خون میباشد که با توجه به قرار داشتن شهر سبزوار در منطقه آندمیک این ویروس، تعیین فراوانی آلودگی به این ویروس در اهداکنندگان خون این شهر ضروری میباشد. مواد و روشها: در یک مطالعه ...
To investigate the role of viral expression in individuals infected with human T-cell lymphotropic virus type 1 (HTLV-1), a real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) of HTLV-1 tax messenger RNA (mRNA) using ABI Prism 7700 Sequence Detection System was developed. Using this system, the HTLV-1 tax mRNA load was compared with HTLV-1 proviral DNA load, HTLV-1 T...
BACKGROUND Human T-cell lymphotropic virus type 1 (HTLV-1) infection can increase the risk of developing skin disorders. This study evaluated the correlation between HTLV-1 proviral load and CD4(+) and CD8(+) T cells count among HTLV-1 infected individuals, with or without skin disorders (SD) associated with HTLV-1 infection [SD-HTLV-1: xerosis/ichthyosis, seborrheic dermatitis or infective der...
در این مطالعه هدف ما طراحی یک سنجش سریع به منظور غربالگری سریع و آسان نمونه¬های سرمی از نظر ابتلاء به هپاتیت b و htlv-i بود. برای این منظور سه آنتی ژن تشخیصی hbc، gp46 و p19 انتخاب گردید. آنتی ژن های انتخاب شده با استفاده از روش های مختلف فیزیکوشیمیایی نقشه¬برداری اپی توپی شدند. قطعات انتخاب شده با لینکرهای اسیدآمینه¬ای (توالی: gsggsg) به هم متصل شده و پروتئین کایمر نوترکیب تشخیصی طراحی گردید. ...
Background and Aims: Human T-lymphotropic virus type 1 (HTLV-1) is a member of retroviridae family that causes ATL and HAM/TSP. Many inflammatory diseases are associated with this virus, such as Sjögren's syndrome, Hashimoto's thyroiditis, Uveitis and also Atherosclerosis. HTLV-1 performs in long latency period and can activate the immune responses in coronary vessels. Activated immune sys...
