background: human t-lymphotropic virus (htlv), a retrovirus, is the causative agent of adult t-lymphocytic leukemia (atl) and tropical spastic paraparesia (tsp). htlv-1 is transmitted mainly through blood transfusion. sabzevar is an endemic region for htlv infection; hence it is essential to detect the prevalence of htlv1/2 infection in the blood donors of this city. materials and methods: in t...

background human t-lymphotropic virus type i (htlv-i) is one of the health threatening problems in endemic areas and can be transmitted by different routes such as blood transfusion. in order to correct chronic anemia in thalassemia subjects, they may need to get blood units per month. thus, they are at risk of infection with blood-borne viruses such as htlv-i. objectives in the present study, ...

Human T-lymphotropic virus type 1 (HTLV-1) infection causes adult T-cell leukemia and several lymphocyte-mediated inflammatory diseases. Persistent HTLV-1 infection is determined by a balance between host immune responses and virus spread. Immunomodulatory therapy involving HTLV-1-infected patients occurs in a variety of clinical settings. Knowledge of how these treatments influence host-virus ...

Abstract Chronic Infection of Hepatitis B virus (HBV) is one risk factor hepatocellular carcinoma (HCC). Much effort has been made to research the process HBV-associated HCC, but its molecular mechanisms carcinogenesis remain vague. Here, weighted gene co-expression network analysis (WGCNA) was employed explore co-expressed modules and hub/key genes correlated HCC. We found that most significan...

BACKGROUND Retrovirus infections among injecting drug users (IDUs), a core at-risk population for both HIV-1 and HTLV-I/II infections in Brazil, were assessed within an ongoing cooperative research. OBJECTIVE The study assessed the seroprevalences of HIV-1 and HTLV-I/II infections, as well as the prevalence of HIV-1 subtypes in a sample of IDUs from Rio de Janeiro, Brazil. An attempt to evalu...

HTLV-1 is implicated in the development of diverse diseases. However, most HTLV-1-infected individuals remain asymptomatic. How HTLV-1 infection leads to disparate consequences remains a mystery, despite extensive investigation of HTLV-1 isolates from infected individuals. As in human infection, experimental HTLV-1 infection in rabbits is generally benign, although HTLV-1-infected rabbit T cell...

Human T-cell lymphotropic virus type-II (HTLV-II) infection is endemic in indigenous groups in the Americas and injection drug users (IDUs) worldwide. In Peru, HTLV-II infection was previously identified in two indigenous Amazonians. We examined risk factors for HTLV-II infection in 2,703 Peruvian men who have sex with men (MSM): 35 (1.3%) were HTLV-II positive. HTLV-II infection was associated...

Human T lymphotropic Virus type 1 (HTLV-1) is the etiological agent of Adult T cell Leukemia/Lymphoma (ATLL) and HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP). Both CD4+ T-cells and dendritic cells (DCs) infected with HTLV-1 are found in peripheral blood from HTLV-1 carriers. We previously demonstrated that monocyte-derived IL-4 DCs are more susceptible to HTLV-1 infection...

UNLABELLED The establishment of a latent reservoir by human tumor viruses is a vital step in initiating cellular transformation and represents a major shortcoming to current therapeutic strategies and the ability to eradicate virus-infected cells. Human T-cell leukemia virus type 1 (HTLV-1) establishes a lifelong infection and is linked to adult T-cell leukemia lymphoma (ATLL). Here, we demonst...
