About the Project
A fully funded 3.5 year PhD project is available in the Gaunt group, The Roslin Institute, University of Edinburgh to investigate how rotavirus A interacts with the host. Rotaviruses are a diverse group of human and animal diarrhoeagenic pathogens which cause an estimated 50,000 deaths in people each year as well as huge economic burden to the farming industry. Despite their economic, health and veterinary importance, we know surprisingly little about how these viruses interact with the host cells they infect.
All viruses encode a number of proteins which are essential for their replication. Additionally, for many viruses, a suite of ‘accessory’ proteins has been identified – proteins encoded by only a subset of viral strains, but which impact aspects of virus replication such as regulation of the innate immune response. For rotaviruses, the identification and characterisation of such proteins has been significantly hindered by the lack of a system in which to modify the genetic sequence of the virus in a controlled manner. This limitation was recently overcome with the development of a reverse genetics system for rotaviruses (Kanai et. al., PNAS, 2017).
In this project, you will use lab based and bioinformatic approaches to identify and characterise previously unknown accessory proteins encoded by rotaviruses. This work will contribute to our understanding of the biology of a very important but highly understudied human and animal pathogen. The Gaunt lab is experienced in studying the molecular biology of rotaviruses (Gaunt et. al., JGV, 2013), and the Digard lab has a proven record of characterising viral accessory proteins (Wise, Gaunt et. al., bioRxiv, 2019).
This project will offer training in techniques including cell culture, PCR, cloning, western blotting, virus infections, viral mutagenesis, sequencing and bioinformatic analyses.
