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

Rapid CYBERNOSE ® detection of illicit drugs and precursor chemicals. This project aims to develop a novel biosensor prototype based on CYBERNOSE® technology to rapidly identify volatile traces of illicit drugs and precursor chemicals in concealed environments. The CYBERNOSE® technology employs sensors using the highly sophisticated and sensitive olfactory receptors of microscopic nematode worms linked to an optoelectronic detector. The need for rapid, non-contact screening devices to detect and identify illicit drugs and precursors entering Australia has never been greater. Law enforcement agencies should directly benefit from the capability to more rapidly screen people and cargo, improving efficiency of illicit drug detection and protection of our borders.Read moreRead less
Development of new tools for surveillance of chlamydial infections in sheep. This project aims to improve health in sheep and reduce on-farm losses for Australian producers, by developing new serological tests for chlamydial infections in sheep. These infections can result in significant on-farm losses and loss of trade in the live export industry. Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret.

This project aims to improve health in sheep and reduce on-farm losses for Australian producers, by developing new serological tests for chlamydial infections in sheep. These infections can result in significant on-farm losses and loss of trade in the live export industry. Currently, surveillance of chlamydial infections is hindered by outdated serological tools that are unreliable and difficult to interpret. The serological tests to be developed aim to be species-specific tests to detect the most important chlamydial sheep pathogens. This in turn endeavours to improve domestic surveillance, reducing on-farm losses and costs, and improve market opportunities for Australian sheep exporters as well as informing veterinary populations on best practice treatment.Read moreRead less
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development
Funder

$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.

An 800 MHz high-resolution nuclear magnetic resonance (NMR) spectrometer equipped with a triple-resonance cryoprobe is required to support the research of 5 universities in the NSW/ACT area. The high magnetic field of the spectrometer is necessary for the study of proteins, protein-ligand complexes and other biomolecular systems of molecular weight >30,000. Projects previously inaccessible due to sensitivity, solubility or resolution problems will become tractable. The increased turn-around times afforded by the high sensitivity of the cryo-enabled spectrometer make it possible to provide access for Australian institutions that would not otherwise have access to comparable equipment.Read moreRead less
