Summary
We have developed a novel animal model by which to study arthritic disease caused by insect-transmitted viruses known as arboviruses. The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal.

The existence of this model and novel reagents provides an excellent opportunity to further explore the basic mechanisms of infectious disease in a complete functioning animal, rather than specific cultured cells. The study will use modern approaches in molecular and cellular biology to achieve this goal. The production by our immune systems of soluble mediators (cytokines-chemokines) and antibodies is an overwhelming positive aspect of our physiological response to infection by microbes. Protection from disease by these immune compounds can happen naturally, or the body's ability to produce these factors can be exploited to our benefit via the administration of vaccines. However, these factors can also be detrimental to the host contributing to severe disease. For instance, work performed almost 40 years ago showed for the first time that under particular conditions, antibodies against viruses can enhance infection, instead of inhibiting infection as normally seen. In the intervening years work by scientists all over the world has associated antibody-dependent enhancement (ADE) of infection to many types of viruses; ADE is even thought to be a risk factor to serious disease with dengue virus, and has been shown in vitro for the AIDS virus and Ebola virus. We have recently discovered a molecular mechanism which explains how antibody enhances viral infection in vitro. In studies on immune cells infected with Ross River Virus (RRV) we found that infection helped by antibody resulted in the specific disruption to the production of cellular chemicals which are toxic to viruses. Are these mechanisms of antibody-enhanced infection also found in animals? Will such mode of infection cause enhanced disease and tissue pathology (arthritis) in animals?Read moreRead less
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development

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.
Arbovirus Activation And Modulation Of NLRP3 Inflammasome

Summary
This project aims to establish how mosquito borne viruses such as Ross River and dengue viruses interacts with the human host to cause disease, including how the virus evades the host’s immune response to persist and cause disease for prolonged periods. Knowing how differences in the virus and the host’s immune system interplay to cause asymptomatic to severely disabling disease will assist in devising new treatments and prevention programs to lessen the impact of these diseases in Australia.

Vitality and change in Warlpiri songs at Yuendumu. This project aims to understand the reasons behind the reported decline in knowledge of songs amongst younger generations at Yuendumu in the past 40-50 years, using a Central Australian music archive. This project will analyse selected song repertories over time, with insights and advice from today's senior custodians; and design strategies for Warlpiri people to re-engage with this important body of Warlpiri-initiated research in their own country. This research is expected to reinvigorate inter-generational transfer of highly significant cultural knowledge and practices.Read moreRead less

Reducing Indigenous incarceration using Justice Reinvestment: an exploratory case study. Utilising Justice Reinvestment methodology, this project explores the conditions, governance and cultural appropriateness of re-investing resources otherwise spent on incarceration, into services to enhance juvenile offenders’ ability to remain in their community to reduce further criminal behaviours and health costs associated with incarceration.
Indigenous young people's resilience and wellbeing. This project aims to identify factors related to, and those which predict, the development of resilience and wellbeing in Indigenous youth. Resilience protects the social and emotional wellbeing of youth exposed to high levels of adversity, and reduces the likelihood of substance misuse, violence, and risky behaviour.

This project aims to identify factors related to, and those which predict, the development of resilience and wellbeing in Indigenous youth. Resilience protects the social and emotional wellbeing of youth exposed to high levels of adversity, and reduces the likelihood of substance misuse, violence, and risky behaviour. This project will examine the development of resilience and wellbeing in Indigenous youth; compare Indigenous youth’s self-assessment of their resilience and wellbeing between low and high risk cohorts; and study how community services develop youth wellbeing and resilience. The expected benefit of this research is a better understanding of connections among age, cultural identity, resilience, wellbeing and risky behaviours in Indigenous youth.Read moreRead less
