Difficulties in the diagnosis of HTLV-2 infection in HIV/AIDS patients from Brazil: comparative performances of serologic and molecular assays, and detection of HTLV-2b subtype Dificuldades no diagnóstico de infecção por HTLV-2 em pacientes com HIV/Aids do Brasil: análise comparativa de ensaios sorológicos e moleculares e detecção de subtipo HTLV-2b

Revista do Instituto de Medicina Tropical de São Paulo, 2007
The current diagnosis of human T-lymphotropic virus type-2 (HTLV-2) infection is based on the search of specific antibodies; nevertheless, several studies conducted in Brazil pointed deficiencies of the commercially available kits in detecting HTLV-2 ...

HTLV-1 Tax-1 interacts with SNX27 to regulate cellular localization of the HTLV-1 receptor molecule, GLUT1 [PDF]

, 2019
An estimated 10–20 million people worldwide are infected with human T cell leukemia virus type 1 (HTLV-1), with endemic areas of infection in Japan, Australia, the Caribbean, and Africa.

HTLV-1 and HTLV-2: highly similar viruses with distinct oncogenic properties [PDF]

Frontiers in Microbiology, 2014
HTLV-1 and HTLV-2 share broad similarities in their overall genetic organization and expression pattern, but they differ substantially in their pathogenic properties. This review outlines distinctive features of HTLV-1 and HTLV-2 that might provide clues to explain their distinct clinical outcomes.

Prevalence of Human T-lymphotropic virus type 1 and 2 among blood donors in Manaus, Amazonas State, Brazil

Revista do Instituto de Medicina Tropical de São Paulo, 2017
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.

Fine tuning of the temporal expression of HTLV-1 and HTLV-2 [PDF]

Frontiers in Microbiology, 2013
Human T-cell leukemia virus types 1 and 2 (HTLV-1 and HTLV-2) are delta retroviruses that share a common overall genetic organization, splicing pattern, and ability to infect and immortalize T-cells in vitro. However, HTLV-1 and HTLV-2 exhibit a clearly distinct pathogenic potential in infected patients. To find clues to the possible viral determinants

Absence of HTLV-1/2 infection and dermatological diseases in Manaus, State of Amazonas, Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 2014
Introduction The prevalence of human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2) infection is heterogeneous across different populations. We tested the hypothesis that HTLV-1/2 infection occurs more often in dermatological patients.

Vírus Linfotrópicos de células T humanas (HTLV-1 e HTLV-2): revisão de literatura / Human T-cell lymphotropic viruses (HTLV-1 and HTLV-2): literature review

Brazilian Journal of Health Review, 2021
Os vírus linfotrópicos de células T humanas (HTLV) foram os primeiros retrovírus potencialmente oncogênicos a serem descobertos e isolados no mundo. Estima-se que 15 a 20 milhões de pessoas estejam infectadas pelo vírus. Até a atualidade, quatro variantes foram descobertas e descritas: HTLV-1, 2, 3 e 4.

Prevalence of human T-lymphotropic virus type 1 and 2 (HTLV-1/-2) infection in pregnant women in Brazil: a systematic review and meta-analysis

Scientific Reports, 2021
Human T-lymphotropic virus type 1 (HTLV-1) infection may cause serious disease, while pathogenicity of HTLV-2 is less certain. There are no screening or surveillance programs for HTLV-1/-2 infection in Brazil.

Functional analysis of human T lymphotropic virus type 2 Tax proteins [PDF]

, 2006
Background The Tax proteins encoded by human T lymphotropic virus type 1 (HTLV-1) and type 2 (HTLV-2) are transcriptional activators of both the viral long terminal repeat (LTR) and cellular promoters via the CREB and NFkB pathways. In contrast to HTLV-1,

Ancient, independent evolution and distinct molecular features of the novel human T-lymphotropic virus type 4

Retrovirology, 2009
Background Human T-lymphotropic virus type 4 (HTLV-4) is a new deltaretrovirus recently identified in a primate hunter in Cameroon. Limited sequence analysis previously showed that HTLV-4 may be distinct from HTLV-1, HTLV-2, and HTLV-3, and their simian ...
