Mosquito gut may hold the key to preventing Dengue and Zika

A mosquito's ability to replicate and transmit a virus depends on the metabolic environment of tissues in its midgut: the primary site of infection. By targeting the sphingolipid pathway, which links together several pathways important for cell signaling and subcellular structure that are altered by virus infection, researchers could devise strategies that stall viral replication in the mosquito and prevent its transmission to humans.
