Low DNA HTLV-2 proviral load among women in São Paulo City [PDF]

Virus Research, 2008
HTLV-2 infections are almost always asymptomatic, and diseases associated with the infection are rarely reported. Little information is available on the relationship between HTLV-2 proviral load and gender or expression of disease, especially among patients with HIV-1 co-infection.We studied 77 HTLV-2-infected subjects followed in our clinic for the ...

Epidemiological analysis of HTLV-1 and HTLV-2 infection among different population in Central China. [PDF]

PLoS ONE, 2013
BACKGROUND: HTLV-1 and HTLV-2 are retroviruses linked etiologically to various human diseases, and both of them can be transmitted by vertical route, sexual intercourse, blood transfusion and intravenous drug use.

HTLV-2 infection in injection drug users in King County, Washington [PDF]

Scandinavian Journal of Infectious Diseases, 2006
Human T-cell lymphotropic virus type 2 (HTLV-2) is endemic in injection drug users (IDU), and native American populations in the Americas. Transmission is associated with high-risk injection and sexual practices. A cohort of 2561 IDU in King County, Washington completed 2 study visits over 1 y.

Making Visible HTLV Infection in a Non-endemic Area of Argentina

Frontiers in Medicine, 2022
In Argentina, the human T-cell lymphotropic virus type 1 (HTLV-1) infection has been documented mainly among blood banks with a prevalence of ~0.02–0.046% for Buenos Aires city, 0.8% for the northeast, and 1% for the northwest; both areas are considered ...

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 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.

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.
