The main mode of mother-to-child transmission the human T-cell leukemia virus (HTLV)-1 is through breastfeeding. Although most reliable nutritional regimen to prevent HTLV-1 exclusive formula feeding, a recent meta-analysis revealed that short-term breastfeeding within 90 days does not increase risk infection. protocol Japanese Health, Labor, and Welfare Science Research Group primarily recomme...

The aim of the present paper is to formulate two new mathematical models describe co-dynamics severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human T-cell lymphotropic virus type-I (HTLV-I) in a host. characterizes interplaying between seven compartments, uninfected ECs, latently SARS-CoV-2-infected actively free SARS-CoV-2 particles, CD4+T cells, HTLV-I-infected cells cells. i...

Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...

Desde o descobrimento e caracterização do retrovírus (HTLV-i) a sua associação com algumas neoplasias de células T periféricas, muitos avanços foram alcançados quanto aos aspectos etiopatológicos da leucemia/linfoma adulto (LLTA). Estudos soroepidemiológicos anti-HTLV-I realizados em diversas partes mundo demonstraram que: HTLV-I é agente etiológico LLTA paraparesia espástica tropical (TSP); te...

  Objective(s): HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV- I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated.   Materials and...

Background and Aims: Human T-lymphotropic virus (HTLV) is a human retrovirus which has been known to cause adult T-cell leukemia/lymphoma and some other inflammatory disorders. Patients with hereditary bleeding diseases are at high risk for these viruses. In this study, we evaluated serological HTLV-I/II infection among these patients in west Azerbaijan of Iran. Material and Methods: We stud...

Background: The northeast of Iran is one the endemic regions human T-cell lymphotropic virus type-1 (HTLV-1). This study aimed to evaluate relationship between nasopharyngeal carcinoma and HTLV-1 infection in Iran, an area for HTLV-1. Methods: In this case-control study, paraffin-embedded tissue samples patients with definitive were evaluated presence genome by polymerase chain reaction retrosp...

Background: Retroviruses of human T-lymphotropic viruses (HTLV-1 and HTLV-2) have been demonstrated to be endemic in the north-eastern region of Iran. This study aims to determine HTLV-1 and HTLV-2 prevalence among healthy individuals in Neyshabur City during 2010-2014. Methods: A total of 8054 blood samples were collected from healthy participants in Neyshabur, North-Eastern Iran. The blood sa...
