Integration of HIV-1 genome in CD4(+) T cells produces latent reservoirs with long half-life that impedes the eradication of the infection. Control of viral replication is essential to reduce the size of latent reservoirs, mainly during primary infection when HIV-1 infects CD4(+) T cells massively. The addition of immunosuppressive agents to highly active(More)
HIV-1 replication is efficiently controlled by the regulator protein Tat (101 amino acids) and codified by two exons, although the first exon (1-72 amino acids) is sufficient for this process. Tat can be released to the extracellular medium, acting as a soluble pro-apoptotic factor in neighboring cells. However, HIV-1-infected CD4(+) T lymphocytes show a(More)
Once HIV-1 enters the target cell, the first goal in the viral cycle is to integrate into the cellular chromosomes. The irreversible integration as a provirus allows HIV-1 to persist in the infected cell in a quiescent or latent stage that leads to viral escape from immune response and current antiviral treatment. HIV-1 replication is absolutely dependent(More)
Background: HIV-infected T cells are quite resistant to apoptosis. Results: Intracellular expression of HIV-1 Tat in T cells stabilized the mitochondrial membrane and reduced caspase activation mainly through NF-κB activation. Conclusion: Intracellular Tat induced resistance to FasL-mediated apoptosis in T cells mainly through the second exon. Significance:(More)
Background: Many HIV databases and applications focus on a limited domain of HIV knowledge. Since even a ''simple'' organism like HIV represents a very complex system with many interacting elements, the fractured structure of existing databases and applications likely limits our ability to investigate and understand HIV. To facilitate research, therefore,(More)
