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

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.
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.

Australia urgently needs new technologies to prevent and fight crime and terrorism. This equipment will address current outstanding problems in forensic science and related disciplines, namely the requirement to (1) analyse minute quantities of samples, (2) differentiate samples with similar matrices but trace differences, (3) analyse solid samples that are difficult to analyse by current techniques. This equipment is also vital for research which will improve the justice system, the quality of food and health products and increase industry competitiveness through novel industrial and environmental testing. Acquiring this infrastructure will safeguard and ensure Australia's continuing prosperity.Read moreRead less

The protection of whistleblowers and other internal witnesses to corruption, misconduct and maladministration is a great unsolved problem in public sector governance. Involving 11 integrity institutions, this first national study of internal witness management will describe and compare organisational experience under varying public interest disclosure regimes across the Australian public sector. By identifying and promoting current best practice in workplace responses to public interest whistleblowing, the project will use the experience and perceptions of internal witnesses and first- and second-level managers to identify more routine strategies for preventing, reducing and addressing reprisals and other whistleblowing-related conflicts.Read moreRead less

Through developing best practice models for managing vicarious trauma in investigators of Internet child exploitation, the project will result in enhanced job satisfaction and less burnout of workers, and reduced health costs for policing organisations. Thus the project addresses a serious occupational health issue and contributes to the goal of promoting and maintaining good health. Further, by better managing the occupational health of investigators, the project will enhance the capacity of police organisations to deliver on their mission of investigating and preventing Internet child exploitation. This in turn contributes to the reduced consumption of Internet child exploitation and the associated traumatisation of abused victims. Read moreRead less
