Human T-cell leukemia viruses type 1 and 2 (HTLV-1 and HTLV2) share a common genetic organization, expression strategy and ability to infect and immortalize T-cells in vitro; however, HTLV-1 and HTLV-2 are strikingly different in terms of clinical impact. HTLV-1 is recognized as the aetiological agent of adult T-cell leukemia/lymphoma (ATLL), and HTLV-associated myeolopathy/tropical spastic par...
The lifelong infection with the human T lymphotropic virus type 1 (HTLV-1) has been associated a variety of clinical manifestations; one less-explored is HTLV-1-associated pulmonary disease. Imaging lung damage caused by HTLV-1 hyperinflammatory cascade can be similar to sequelae from TB infection. Our study aims describe lesions HTLV-1-positive patients without past or current active and evalu...
Human T-cell leukemia virus type I (HTLV-I) is the causative agent of adult T-cell leukemia (ATL). However, the low incidence of ATL among HTLV-I-infected carriers, together with a long latent period, suggests that multiple host-viral events are involved in the progression of HTLV-I-dependent transformation and subsequent development of ATL. Human thioredoxin (TRX) is a redox active protein hig...
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...
Human T-lymphotropic virus type 1 (HTLV-1) is found in indigenous peoples of the Pacific Islands and the Americas, whereas type 2 (HTLV-2) is widely distributed among the indigenous peoples of the Americas, where it appears to be more prevalent than HTLV-1, and in some tribes of Central Africa. HTLV-2 is considered ancestral in the Americas and is transmitted to the general population and injec...
هدف: تعیین شیوع موارد سرولوژی مثبت از نظر ویروس لنفوتروپیک یاخته انسانی نوع 1 و 2 (2و1-HTLV) در بین دهندگان بانک چشم جمهوری اسلامی ایران بین سال‌های 1386-1384. روش پژوهش: نتایج سرولوژی همه دهندگان در فاصله زمانی مرداد 1384 تا تیر 1386 از نظر ویروس 2و1-HTLV ارزیابی شدند. در مورد دهندگان HTLV- مثبت، گزارش‌های بیمارستانی و پزشکی قانونی و محل تولد آن‌ها نیز بررسی شدند. یافته‌ها: در مجموع، نتایج...
The first description of the human T-lymphotropic virus type 1 (HTLV-1) was made in 1980, followed closely by the discovery of HTLV-2, in 1982. Since then, the main characteristics of these viruses, commonly referred to as HTLV-1/2, have been thoroughly studied. Central and South America and the Caribbean are areas of high prevalence of HTLV-1 and HTVL-2 and have clusters of infected people. Th...
Molecular studies have demonstrated the existence of at least two major subtypes of human T-cell lymphotropic virus type 2 (HTLV-2), designated HTLV-2a and HTLV-2b. To further investigate the heterogeneity of this family of viruses, we have characterized the HTLV-2 subtypes present in several urban areas in Brazil. DNAs from peripheral blood mononuclear cells of a large number of infected indiv...
INTRODUCTION Transmission of human T-lymphotropic viruses (HTLV) occurs from mother to child, by sexual contact and blood transfusion. Presently, in most centres in Nigeria, there is no routine pre-transfusion screening for HTLV. The study aims to determine the prevalence of HTLV-1 and HTLV-2 among healthy blood donors at a tertiary centre in Lagos. METHODS A cross-sectional study was carried...
