BACKGROUND Bovine leukemia virus (BLV) is worldwide distributed and highly endemic in Argentina. Among the strategies to prevent BLV dissemination, a control plan based on the selective segregation of animals according to their proviral load (PVL) is promising for our dairy productive system. The objective of this work was to study the relationship between the blood PVL and the antibody level, ...
BACKGROUND HTLV-2 infections are almost always asymptomatic, and diseases associated with the infection are rarely reported. Little information is available on the relationship between HTLV-2 proviral load and gender or expression of disease, especially among patients with HIV-1 co-infection. METHODS We studied 77 HTLV-2-infected subjects followed in our clinic for the last 9 years; 53 (69%) ...
An external quality assurance program was developed for HIV-1 RNA viral load measurements taken from dried blood spots using a reference panel and field-collected specimens. The program demonstrated that accurate and reproducible quantitation can be obtained from field-collected specimens. Residual proviral DNA may confound interpretation in virologically suppressed subjects.
Chromatin influences Human Immunodeficiency Virus (HIV) integration and replication. This review highlights critical host factors that influence chromatin structure and organization and that also impact HIV integration, transcriptional regulation and latency. Furthermore, recent attempts to target chromatin associated factors to reduce the HIV proviral load are discussed.
Human T-lymphotropic virus-type 1 (HTLV-1) is the etiologic agent of the neurologic disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Tax viral protein plays a critical role in viral pathogenesis. Previous studies suggested that extracellular Tax might involve cytokine-like extracellular effects. We evaluated Tax secretion in 18 h-ex vivo peripheral blood mononuclear ...
Background: Raltegravir is the first approved antiretroviral able to prevent HIV genome integration into the host chromosomes. The aim of the study is to test if raltegravir plasma concentrations can be associated with proviral DNA decline during raltegravir-based salvage therapy. Methods: A total of 33 multidrug-resistant HIV-infected patients were enrolled in a longitudinal open-label pilot s...
BACKGROUND Bovine leukemia virus (BLV) is highly endemic in many countries, including Argentina. As prevention of the spread from infected animals is of primary importance in breaking the cycle of BLV transmission, it is important to know the pathophysiology of BLV infection in young animals, as they are the main source of animal movement. In this work, we determined the proviral load and antib...
HTLV-1–associated myelopathy/tropical spastic paraparesis (HAM/TSP) develops in a subset of human T lymphotropic virus type I (HTLV-I)–infected individuals.1 Its evolution is chronic and progressive, without remission.2 Recently, a study using a histone deacetylase inhibitor reported, for the first time, a spectacular decline in the HTLV-I proviral load in a series of HAM/TSP patients.3 Unfortu...
