Seroprevalence of HTLV-1 and HTLV-2 amongst mothers and children in Malawi within the context of a systematic review and meta-analysis of HTLV seroprevalence in Africa [PDF]

, 2016
OBJECTIVES: Human T‐lymphotropic virus (HTLV)‐1 causes T‐cell leukaemia and myelopathy. Together with HTLV‐2, it is endemic in some African nations. Seroprevalence data from Malawi are scarce, with no reports on associated disease incidence.

Crosstalk Between Intratumoral Microbes and Tumor Immunity: Implications for Tumor Therapy

Cancer Medicine, Volume 15, Issue 2, February 2026.
ABSTRACT Background Emerging studies indicate that microbes are present in tumor cells and immune cells. Intratumoral microbiota (ITM) constitute an important component of the tumor immune microenvironment (TIME) and have an important impact on tumor progression and treatment. Objective Through the general elaboration of ITM represented by bacteria and

Harnessing viral footprints in circulating free DNA (cfDNA) for early cancer detection: A focus on liquid‐biopsy‐based screening

International Journal of Cancer, Volume 158, Issue 3, Page 511-526, 1 February 2026.
Abstract Viral infections play a significant role in cancer development, making detecting viral signatures a promising approach for early cancer diagnosis. Circulating free DNA (cfDNA), released into the bloodstream by tumors and other cells, has emerged as a powerful biomarker for non‐invasive cancer screening.

Expression of alternatively spliced human T-cell leukemia virus type 1 mRNAs is influenced by mitosis and by a novel cis-acting regulatory sequence [PDF]

, 2016
Human T-cell leukemia virus type 1 (HTLV-1) expression depends on the concerted action of Tax, which drives transcription of the viral genome, and Rex, which favors expression of incompletely spliced mRNAs and determines a 2-phase temporal pattern of ...

Human T‐Lymphotropic Virus Type 1 and 2 Seroprevalence among first‐time blood donors in Chile, 2011–2013

Journal of Medical Virology, 2015
Infection with human T‐lymphotropic virus type 1/2 (HTLV‐1/2) is a major health problem. HTLV‐1/2 infection is endemic in Chile but representative donor prevalence data are lacking. Data on all blood donors in a large network of Chilean blood centers were examined during 2011–2013.

Failure of dideoxynucleosides to inhibit human immunodeficiency virus replication in cultured human macrophages. [PDF]

, 1987
Primary human monocyte-derived macrophages (MDM) were shown to have diminished deoxynucleoside kinase activities compared to T lymphoblasts, and a reduced ability to phosphorylate dideoxynucleosides with anti-human immunodeficiency virus (HIV) activity ...

The origin and prevention of pandemics. [PDF]

, 2010
Despite the fact that most emerging diseases stem from the transmission of pathogenic agents from animals to humans, the factors that mediate this process are still ill defined.

Zika virus surveillance post‐epidemic in blood donors from São Paulo, Brazil 2016–2020

Transfusion Medicine, Volume 36, Issue 1, Page 59-65, February 2026.
Abstract Introduction Zika virus (ZIKV) is primarily transmitted through the bite of the Aedes aegypti mosquito, though transmission via blood transfusion has also been documented. During the 2015 ZIKV epidemic in Brazil, severe complications were observed in pregnant women, leading to fetal microcephaly. This study evaluated the persistence of ZIKV in

Human T-Cell Lymphotropic Virus: A Model of NF-κB-Associated Tumorigenesis

Viruses, 2011
Human T-cell lymphotropic virus type 1 (HTLV-1) is the etiological agent of adult T-cell leukemia/lymphoma (ATL), whereas the highly related HTLV-2 is not associated with ATL or other cancers.
