چکیده

Human immunodeficiency virus (HIV) load is suppressed during dengue virus infection. The NS5A phosphoprotein of GB virus C (a related flavivirus) inhibits HIV replication in vitro. To determine whether the dengue virus NS5 protein inhibits HIV replication, CD4(+) T cell lines expressing this protein were generated. HIV replication in dengue virus NS5-expressing cells decreased by >90% compared with control cells (P < .01), and this was mediated in part by decreased HIV coreceptor (CXCR4) expression and increased production of SDF-1. Thus, the dengue virus NS5 protein inhibits HIV replication in vitro, potentially explaining the reduction in HIV load observed during acute dengue virus infection.

Viruses within the Flaviviridae decrease CD4 expression and inhibit HIV replication in human CD4+ cells.

Viral infections alter host cell homeostasis and this may lead to immune evasion and/or interfere with the replication of other microbes in coinfected hosts. Two flaviviruses are associated with a reduction in HIV replication or improved survival in HIV-infected people (dengue virus (DV) and GB virus type C (GBV-C)). GBV-C infection and expression of the GBV-C nonstructural protein 5A (NS5A) an...

Assessment of HTLV-I proviral load, HIV viral load and CD4 T cell count in infected subjects; with an emphasis on viral replication in co-infection

  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...

Dengue virus nonstructural protein NS5 induces interleukin-8 transcription and secretion.

Elevated circulating levels of chemokines have been reported in patients with dengue fever and are proposed to contribute to the pathogenesis of dengue disease. To establish in vitro models for chemokine induction by dengue 2 virus (DEN2V), we studied a variety of human cell lines and primary cells. DEN2V infection of HepG2 and primary dendritic cells induced the production of interleukin-8 (IL...

Cyclosporine inhibits flavivirus replication through blocking the interaction between host cyclophilins and viral NS5 protein.

Although flaviviruses cause significant human diseases, no effective therapy is currently available. Host factors essential for viral replication are potential targets for antiviral development. Here we report that cyclophilins (CyPs), a family of cellular peptidyl-prolyl isomerases (PPIases), play a role in flavivirus replication. Huh-7.5 cells with knockdown of different isoforms of CyP were ...
