Mosquitoes push northern limits with time-capsule eggs to survive winters
Washington University in St. Louis

Invasive mosquitoes at the northern limit of their current range are surviving conditions that are colder than those in their native territory. This new evidence of rapid local adaptation could have implications for efforts to control the spread of this invasive species.

A mouse mother's prior dengue immunity would protects her unborn pups from devastating brain defects such as microencephaly associated with ZIKV. These findings could guide development of more effective flavivirus vaccines and hint at what types of immune responses are maximally protective against fetal brain damage after Zika invasion.

Washington University in St. Louis

Two viruses closely related to Zika – West Nile and Powassan – can spread from an infected pregnant mouse to her fetuses, causing brain damage and fetal death, according to a new study from Washington University School of Medicine in St. Louis. The findings suggest that Zika may not be unique in its ability to cause miscarriages and birth defects.

Although Zika and dengue are considered different virus “species,” they are so closely related that the immune system treats Zika just like another version of dengue, report researchers at La Jolla Institute for Allergy and Immunology. Their latest study, published in the March 13, 2017, advance online edition of Nature Microbiology, shows that pre-existing immunity to dengue virus modulates the magnitude and breadth of the immune system’s T cell response to Zika.
