Rotavirus is the main cause of severe diarrhoea in children worldwide. In this project, we aim to understand the nature of the first-line immune response to rotavirus in the gut, and elucidate how RV counteracts this response to promote infection. These studies will increase our understanding of how rotavirus causes disease, and facilitate the choice of rotavirus targets for drug development and improved vaccines.
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development
Funder

Funding Amount
$520,520.00
Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
Respiratory Syncytial Virus Matrix Protein-Host Protein Interactions As Targets For Therapeutics
Funder

Funding Amount
$686,885.00
Summary
Respiratory syncytial virus (RSV) causes more deaths in winter than influenza, being the major cause of viral pneumonia in infants worldwide, and a potent lower respiratory pathogen in the elderly and immunosuppressed adults. The present proposal will apply a range of techniques to search for new inhibitors of viral infection which target host-virus interactions, as the first step towards new generation anti-viral agents to treat RSV infection.
Defining The Molecular Mechanisms Of Lyssavirus Replication And Immune Evasion: The P Protein Axis
Funder
National Health and Medical Research Council
Funding Amount
$900,995.00
Summary
Lyssaviruses such as rabies virus (RABV) and Australian bat lyssavirus cause rabies disease, which has the highest case-fatality rate of known infectious diseases, causing >60,000 human deaths/year. Critical to this is a protein produced by the virus that is important for both viral growth and evasion of the host's immune defences. This project aims to understand the molecular mechanisms underlying these processes, which may lead to new approaches to combat currently incurable viral diseases.
