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

Retrovirology, 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,

Work-Related Human T-lymphotropic Virus 1 and 2 (HTLV-1/2) Infection: A Systematic Review [PDF]

Viruses, 2021
Human T-lymphotropic virus 1 and 2 (HTLV-1/2) belong to the delta group of retroviruses which may cause a life-long infection in humans, HTLV-1 leading to adult T-cell leukemia/lymphoma and other diseases. Different transmission modes have been described,

Human T lymphotropic virus types 1 and 2: a point of view [PDF]

Revista Brasileira de Hematologia e Hemoterapia, 2013
Reported at the beginning of the 1980s, Human T lymphotropic viruses type 1 and 2 (HTLV1, HTLV 2) were the first retroviruses to have been detected in human beings. HTLV 1 was isolated from adult T-cell leukemia (ATL) and first described by Takatsuki et al. in Japan in 1976, as a malignancy that only affects T cells and only in adults(1, 2).

Clinical Outcome in Human T-Lymphotropic Virus Type 2 Carriers Following Organ Transplantation [PDF]

Transplantation Proceedings, 2021
Frequent and rapid development of myelopathy has been reported in individuals with human T-lymphotropic virus type 1 (HTLV-1) infection following solid organ transplantation. There is no information regarding HTLV-2, a closely related virus that often infects injection drug users.This study includes a retrospective analysis of all consecutive organ ...

High prevalence of human T-lymphotropic virus 2 (HTLV-2) infection in villages of the Xikrin tribe (Kayapo), Brazilian Amazon region. [PDF]

BMC Infect Dis, 2019
Studies have shown that the human T-lymphotropic virus 2 (HTLV-2) is endemic in several indigenous populations of the Brazilian Amazon and molecular analyses have shown the exclusive presence of HTLV-2 subtype 2c among the indigenous groups of this geographical region.The present study characterizes the prevalence of HTLV-2 infection in three new ...

APOBEC3A, APOBEC3B, and APOBEC3H Haplotype 2 Restrict Human T-Lymphotropic Virus Type 1 [PDF]

Journal of Virology, 2012
ABSTRACT The human APOBEC3 family consists of seven cytidine deaminases (A3A to A3H), some of which display potent antiretroviral activity against HIV-1 and other retroviruses. Studies that analyzed the effect of A3G on human T-lymphotropic virus type 1 (HTLV-1) infectivity resulted in conflicting findings, and our knowledge of ...

Human T-lymphotropic virus type 2 subtype b in a patient with chronic neurological disorder [PDF]

Journal of NeuroVirology, 2014
Human T-cell lymphotropic virus is a retrovirus described worldwide. There are four HTLV types: HTLV-1 to 4. Only HTLV-1 and 2 are linked to human disease. The majority of infected individuals remain asymptomatic. However, it is estimated that 5 % of HTLV-1-infected patients present a clinical neurological disorder called HTLV-1-associated myelopathy ...

Human T Lymphotropic Virus Type 1-Associated Myelopathy/Tropical Spastic Paraparesis in an HIV-Positive Patient Coinfected with Human T Lymphotropic Virus Type 2 Following Initiation of Antiretroviral Therapy [PDF]

Clinical Infectious Diseases, 2007
We describe a patient coinfected with human immunodeficiency virus (HIV) and human T lymphotropic virus type 2 in Spain who developed paraparesis resembling human T lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis shortly after initiation of highly active antiretroviral therapy, hypothetically as the result of an immune ...
