BACKGROUND HIV-1 is characterized by its rapid genetic evolution and high diversity as a consequence of its error-prone reverse transcriptase and genetic recombination. This latter mechanism is responsible for the creation of circulating recombinant forms (CRFs) found in nature. Previous studies from our lab group have shown that the epidemic in Argentina(More)
Elite controllers maintain HIV-1 viral loads below the limit of detection. The mechanisms responsible for this phenomenon are poorly understood. As microRNAs (miRNAs) are regulators of gene expression and some of them modulate HIV infection, we have studied the miRNA profile in plasma from HIV elite controllers and chronically infected individuals and(More)
BACKGROUND Multiple HIV-1 intersubtype recombinants have been identified in human populations. Previous studies from our lab group have shown that the epidemic in Argentina is characterized by the high prevalence of a circulating recombinant form, CRF12_BF, and many related BF recombinant forms. In these genomic structures a recombination breakpoint(More)
BACKGROUND The extreme genetic diversity of the human immunodeficiency virus type 1 (HIV-1) poses a daunting challenge to the generation of an effective AIDS vaccine. In Argentina, the epidemic is characterized by the high prevalence of infections caused by subtype B and BF variants. The aim of this study was to characterize in mice the immunogenic and(More)
HIV-1 intersubtype recombination is a very common phenomenon that has been shown to frequently affect different viral genomic regions. Vpr and Tat are viral proteins known to interact with viral promoter (LTR) during the replication cycle. This interaction is mainly involved in the regulation of viral gene expression, so, any structural changes in the LTR(More)
Extreme genetic variability is the hallmark of HIV‐1 infection and it represents a major challenge for antiviral treatment and vaccine development. HIV‐1 group M dominates the global pandemic. Nine subtypes, 68 circulating recombinant forms (CRF) and countless unique recombinant forms (URF) were described within this group (Los Alamos HIV database,(More)
HTLV-1 is the etiologic agent of Adult T-cell Leukemia/ Lymphoma (ATLL) and HTLV-1 Associated Mielopathy/ Tropical Spastic Paraparesis (HAM/TSP). Tax, a critical viral factor for genomic activation and viral gene expression , has been implied in cell transformation. The aim of this study was to analyze the presence of nucleotide poly-morphisms in the tax(More)
