Infectious Agents As Markers of Human Migration toward the Amazon Region of Brazil

Frontiers in Microbiology, 2017
Infectious agents are common companions of humans and since ancient times they follow human migration on their search for a better place to live. The study of paleomicrobiology was significantly improved in its accuracy of measurement with the constant ...

Is the human T-cell lymphotropic virus type 2 in the process of endogenization into the human genome?

Journal of Virus Eradication, 2020
Human T-cell lymphotropic virus type 2 (HTLV-2) infection has been shown to be endemic among intravenous drug users in parts of North America, Europe and Southeast Asia and in a number of Amerindian populations.

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

Revista do Instituto de Medicina Tropical de São Paulo, 2017
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.To estimate the seroprevalence of HTLV-1/2 and to identify circulating subtypes among blood donors in Manaus.Blood donors (2001-2003)

HIV-1 and HTLV-1 Transmission Modes: Mechanisms and Importance for Virus Spread

Viruses, 2022
So far, only two retroviruses, human immunodeficiency virus (HIV) (type 1 and 2) and human T-cell lymphotropic virus type 1 (HTLV-1), have been recognized as pathogenic for humans. Both viruses mainly infect CD4+ T lymphocytes.

Pathways of cell-cell transmission of HTLV-1

Frontiers in Microbiology, 2012
The deltaretroviruses human T-cell lymphotropic virus type 1 (HTLV-1) and human T-cell lymphotropic virus type 2 (HTLV-2) have long been believed to differ from retroviruses in other genera by their mode of transmission.

Resistance to Fas-Mediated Apoptosis of Human T-Cell Lines Expressing Human T-Lymphotropic Virus Type-2 (HTLV-2) Tax Protein

Virology, 2001
The susceptibility to Fas-mediated apoptosis was evaluated in seven T-cell lines (two infected with HTLV-2, one with HTLV-1, and four HTLV-free) as well as in Jurkat cells transfected with a Tax-2 expressing vector. Fas-mediated apoptosis was significantly reduced in the HTLV-1- and HTLV-2-infected lines in comparison with the HTLV-free lines ...

Silencers of HTLV-1 and HTLV-2: the pX-encoded latency-maintenance factors

Retrovirology, 2019
Of the members of the primate T cell lymphotropic virus (PTLV) family, only the human T-cell leukemia virus type-1 (HTLV-1) causes disease in humans—as the etiological agent of adult T-cell leukemia/lymphoma (ATLL), HTLV-1-associated myelopathy/tropical ...
