Introduction. Dengue Virus (DENV) and Zika Virus (ZIKV) are viruses that belong to the Flavivirus family. They are transmitted by the Aedes aegypti species of mosquitoes. Infection with DENV can result in no symptoms, mild symptoms which include fever, rash, and headache (dengue fever) or more severe symptoms which include hemorrhage, dengue hemorrhagic fever (DHF) and shock, dengue shock syndrome (DSS). ZIKV, until recently caused mild disease but an outbreak in Brazil was associated with fetal complications such as microcephaly or Guillain-Barré syndrome in adults. Due to the similarity between ZIKV and DENV, antibodies (Abs) generated in humans to these …

Secreted Ns1 Aids In Dengue Virus Entry By Binding Heparan Sulfate, Morgan E. Schafer, Michael Dibiasio-White, Richard J. Kuhn

The Summer Undergraduate Research Fellowship (SURF) Symposium

A large portion of the world’s population lives in an area where they are at risk of contracting Dengue Virus (DENV). While infection with DENV can result in a wide range of clinical manifestations, from flu-like symptoms to hemorrhagic shock, vascular leakage, and even death, no treatments currently exist. Previous studies have shown that higher levels of viral non-structural protein 1 (NS1) in the blood of infected patients correlate with more severe disease. NS1 has been shown to play many roles in the viral lifecycle, but the mechanisms by which NS1 executes these functions are unknown. Preliminary data from our …

Dengue Viral Rna Levels In Peripheral Blood Mononuclear Cells Are Associated With Disease Severity And Preexisting Dengue Immune Status, Anon Srikiatkhachorn, Sineewanlaya Wichit, Robert V. Gibbons, Sharone Green, Daniel H. Libraty, Timothy P. Endy, Francis A. Ennis, Siripen Kalayanarooj, Alan L. Rothman

Alan Rothman

BACKGROUND: Infection with dengue viruses (DENV) causes a wide range of manifestations from asymptomatic infection to a febrile illness called dengue fever (DF), to dengue hemorrhagic fever (DHF). The in vivo targets of DENV and the relation between the viral burden in these cells and disease severity are not known.

METHOD: The levels of positive and negative strand viral RNA in peripheral blood monocytes, T/NK cells, and B cells and in plasma of DF and DHF cases were measured by quantitative RT-PCR.

RESULTS: Positive strand viral RNA was detected in monocytes, T/NK cells and B cells with the highest amounts …
