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.

Summary
Infections with mosquito-borne viruses are increasing at an alarming rate worldwide. Ross River virus is endemic in parts of Australia, PNG and Pacific islands, while chikungunya virus is distributed globally and causes recurrent pandemics that involve millions of people. These viruses cause severe musculoskeletal disease for several months after infection. This project aims to establish how these viruses interact with the human host to cause disease and may provide a basis for new treatments.

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.
Mosquito-borne alphaviruses such as Ross River and chikungunya viruses cause widespread epidemics and exert extreme pressure on the public health systems of affected regions. Alphaviruses spreads to joints and triggers a severe disease in those affected. There are no effective treatments or vaccines. The project will investigate virus-host interaction at the bite site. The outcome will be new knowledge to treat infection at the mosquito bite site to prevent joint disease.

Summary
The newly isolated human metapneumovirus (hMPV) causes significant respiratory illness in infants, young children and the elderly. The virus can persist long-term and may predispose individuals to chronic lung disease. This proposal aims to determine the mechanisms by which hMPV infection causes respiratory disease, with a view to improving treatments and preventing disease.
Glycotherapeutics; A New Class Of Treatment For Alphavirus-induced Musculoskeletal Disease

Summary
The hallmark of alphavirus disease is crippling pain and joint arthritis, which often has an extended duration. Currently there is no licenced specific treatment for alphavirus disease and the increasing spread of infection highlights an urgent need for therapeutic intervention strategies. This grant looks at the potential of pentosan polysulfate as a promising drug-repurposing candidate for the treatment of alphavirus-induced arthritis.
The Role Of Innate Inflammatory Responses In Viral Arthritis

Summary
Viruses are known to cause arthritis (HIV, hepatitis viruses, mosquito borne viruses). Symptoms of viral arthritis include joint pain, stiffness, and swelling. The mechanism of disease is poorly understood. We have developed a novel animal model of disease and human cell culture models by which to study disease caused by viral infections. This models provide an excellent opportunity to explore the mechanisms of rheumatic disease in a functioning animal and to explore new treatment regimes.

Summary
Ross River virus is a mosquito-borne virus that causes arthritis in the joints of many people infected. This project will look at the early interactions of a virulent virus with the mammalian host that appear to enable the virus to replicate and spread in the host and thereby cause disease. These interactions are with the host interferon protein which the virus has developed the ability to inhibit. The effect of the invading virus on the host's interferon system, part of the immune system, will ....Ross River virus is a mosquito-borne virus that causes arthritis in the joints of many people infected.

These interactions are with the host interferon protein which the virus has developed the ability to inhibit.

Summary
Ross River virus and chikungunya virus cause muscle and joint pain that can persist for a long time. This project looks at factors in the human host that affect the disease severity, with the aim of finding new treatments.
Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community.

In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucidate whether there is any association between RRV strain and the severity of human disease. It will also identify viral markers that could assist public health officials in determining likely disease outcomes of outbreaks and could provide new avenues for the design of antiviral strategies.Read moreRead less
