Insect-specific virus host restriction

点击翻译按钮获取中文摘要

Mosquito-borne viruses are a topic of intense research due to their complex biology, ecology and evolution, and their potential to produce unpredictable outbreaks of disease in both humans and animals. Insect-specific viruses (ISVs) are viruses that replicate solely in mosquito cell and are unable to infect vertebrate tissues. This project aims to assess the biodiversity of ISVs in the Australian mosquito population and identify key factors behind their restriction in vertebrates. The objectives of the studies proposed will answer clearly defined important biological questions about ISVs, while also delivering technological advances, novel reagents and potential commercial outcomes for the control and prevention of arboviral disease.
