Publications are often used as a measure of research work success. Human T-lymphotropic virus (HTLV) type 1 and 2 are human retroviruses, which were discovered in the early 1980s, and it is estimated that 15-20 million people are infected worldwide. This article describes a bibliometric review and a coauthorship network analysis of literature on HTLV indexed in PubMed in a 24-year period. A tot...

To investigate serological, epidemiological, and molecular aspects of HTLV-1, HTLV-2, and HIV-1 infections in Amerindian populations in Brazil, we tested 683 and 321 sera from Tiriyo and Waiampi Indians, respectively. Both HIV-1 and HTLV-2 infections were detected at low prevalence among the Tiriyos whereas only HTLV-1 was present among the Waiampis, also at low prevalence. Analysis of the nucl...

In order to asses the soroprevalence of HTLV- I/II, HIV, siphylis, and toxoplasmosis infection among pregnant women seen at Basic Health Units in the municipality of Botucatu - São Paulo - Brazil, and risk factors for HTLV- I/II infection, sorologic surveys were carried out and results of sorologic surveys carried in pregnance routine evaluation were assessed. Seroprevalence was 0.1% (1 in 913)...

Human T-lymphotropic viruses type 1 (HTLV-1) and type 2 (HTLV-2) present very similar genomic structures but HTLV-1 is more pathogenic than HTLV-2. Is this difference due to their transactivating Tax proteins, Tax-1 and Tax-2, which are responsible for viral and cellular gene activation? Do Tax-1 and Tax-2 differ in their cellular localization and in their interaction pattern with cellular fact...

INTRODUCTION Human T-lymphotropic virus type 1 and 2 (HTLV-1/2) is endemic in Brazil, but few studies have investigated the seroprevalence of HTLV and its subtypes among blood donors in the capital city Manaus, Amazonas State, Brazil. AIM To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus. MATERIALS AND METHODS Blood donors (2001-200...

human t-ceil lymphotropic virus, type 1 (htl v-i) is considered to be the causative agent of adult t-cell lymphoma/leukemia and spastic paralysis, and seems to be common in khorasan province. 300 blood samples from mashhadi and 180 from gonbadi blood donors were obtained (all samples from healthy subjects). serological screening was done by passive particje- agglutination test and confirmed by ...

BACKGROUND Various kinds of autoimmune diseases have been reported to have a significant relationship with persistent hepatitis c virus (HCV) infection and Th17 cells. Previously, our group reported that the existence of HCV in T lymphocytes could affect the development of CD4+ helper T cells and their proliferation, in addition to the induction of immunoglobulin hyper-mutation. METHODS There...

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...
