Scripps Florida scientist awarded $2.3 million to study dengue fever and related viruses
Date:3/27/2014

nce engulfed by the phagocyte, the virus quickly turns the cell's own biology on its head, forcing it to produce copies of the virus.

While some viruses (influenza A for example) do not use PS in their life cycle, the flavivirus exploits this opportunity to the hilt. Infection of cells by dengue or West Nile viruses is markedly enhanced when phagocytes express receptors that recognize and bind PS.

It appears, however, that flaviviruses use only a subset of these receptors. The high selectivity, and the potency with which some of these receptors promote flavivirus infection, suggest only a small number of receptors might be effectively targeted to treat these diseases.

"We want to understand which PS receptors contribute the most to flavivirus infections and how we might block them," Choe said. "Our studies are designed to offer insights useful in the development of new therapies."
