Little is known about the transmission or tropism of the newly discovered human retrovirus, human T-cell lymphotropic virus type 3 (HTLV-3). Here, we examine the entry requirements of HTLV-3 using independently expressed Env proteins. We observed that HTLV-3 surface glycoprotein (SU) binds efficiently to both activated CD4(+) and CD8(+) T cells. This contrasts with both HTLV-1 SU, which primari...
Human T-cell lymphotropic virus type 1 , 2 (HTLV-1, 2) is endemic in Particular Areas of the world in which it is associated with myeloid leukemia.In this study, we described the prevalence of HTLV-1, 2 in myeloid leukemia and Mycobacterium Tuberculosis in Iran. We have worked with tissue and blood samples for 2 years. These were the same samples which were positive for myeloid leukemia, Mycoba...
به منظور مقایسه توزیع فراوانی آنتی بادی بر علیه htlv-1 در بیماران تالاسمیک شهر زابل با گروه شاهد در سال 1380 مطالعه ای توصیفی - تحلیلی به صورت مقطعی بر روی 184 نفر (95 بیمار تالاسمیک و 89 فرد سالم) انجام گرفت. ویروسhtlv-1 عامل بیماری نورولوژیک ham/tsp, atl می باشد، این ویروس در بعضی مناطق دنیا بویژه در جنوب ژاپن، جزیره کارائیب و کشورهای اطراف آن و قسمتهایی از آفریقای مرکزی آندمیک شن...
Until now, serologic tests that distinguish the closely related human T-cell lymphotropic virus types I (HTLV-I) and II (HTLV-II) infections have not been available. Synthetic peptide assays, employing peptides derived from the core and envelope proteins of HTLV-I and HTLV-II (SynthEIA and Select-HTLV tests), were evaluated for the ability to serologically discriminate HTLV-I and HTLV-II infect...
The human T-cell lymphotropic virus type I (HTLV-I) is associated with a chronic, progressive neurological disease known as HTLV-I-associated myelopathy/tropical spastic paraparesis. Screening for HTLV-I involves the detection of virus-specific serum antibodies by EIA and confirmation by Western blot. HTLV-I/II seroindeterminate Western blot patterns have been described worldwide. However, the ...
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...
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...
