Human T-lymphotropic virus 1/2 infection among immigrants and refugees in Central Brazil, an emerging vulnerable population

Frontiers in Public Health, 2023
IntroductionMigratory flows play a significant role in the spread of human T-lymphotropic virus 1/2 (HTLV-1/2). In the last decade, a substantial migration of individuals occurred from Haiti and Venezuela to Brazil.

Loss of correlation between HIV viral load and CD4+ T-cell counts in HIV/HTLV-1 co-infection in treatment naive Mozambican patients [PDF]

, 2009
Seven hundred and four HIV-1/2-positive, antiretroviral therapy (ART) naïve patients were screened for HTLV-1 infection. Antibodies to HTLV-1 were found in 32/704 (4.5%) of the patients.

Global stability of a general HTLV-I infection model with Cytotoxic T-Lymphocyte immune response and mitotic transmission

Alexandria Engineering Journal, 2023
Mathematical models have been considered as a robust tool to support biological and medical studies of human viral infections. The global stability of viral infection models remains an important and largely open research problem.

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Is the innate bio-protection power against human virus the same between males and females? A conclusion based on blood donor data of HTLV-I infection [PDF]

, 2008
Human T-cell leukemia virus type I (HTLV-I) is a retrovirus that causes adult T-cell leukemia. The male-to-female transmission is stronger than the reverse, so the carrier proportion of women is greater than that of men.

Extracellular Vesicles in HTLV-1 Communication: The Story of an Invisible Messenger

Viruses, 2020
Human T-cell lymphotropic virus type 1 (HTLV-1) infects 5–10 million people worldwide and is the causative agent of adult T-cell leukemia/lymphoma (ATLL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) as well as other ...

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Mimicry between HTLV-I and myelinbasicprotein: No response in HTLV-I-associatedmyelopathypatients

, 1992
The reactivity to a peptide from the HTLV-I polyprotein (FKLPGLNSR) and a similar sequence from myelinbasicprotein (MBP) (FKLGGRDSR) was examined in relation to the proposal that mimicry of MBP by HTLV-I could be involved in autoimmune responses in HTLV ...

HLA alleles determine human T-lymphotropic virus-I (HTLV-I) proviral load and the risk of HTLV-I-associated myelopathy [PDF]

, 1999
The risk of disease associated with persistent virus infections such as HIV-I, hepatitis B and C, and human T-lymphotropic virus-I (HTLV-I) is strongly determined by the virus load.
