Funding Amount
$594,133.00
Summary
West Nile virus (WNV) is a mosquito-borne virus that causes potentially fatal encephalitis in humans and horses. This project will investigate the recent emergence of pathogenic for horses WNV in Australia and the potential of this new isolate to cause severe disease in humans. We will define the viral and host factors determining the outcome of WNV infection. This project will provide knowledge on the factors involved in the emergence of virulent WNV strains from attenuated isolates.
Novel Insights Into The Pathobiology Of Alphavirus Infections

Funding Amount
$827,660.00
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.
Understanding How Virus Infection Accelerates Type 1 Diabetes Development

Summary
We linked rotavirus infection in children at-risk of type 1 diabetes with faster diabetes development. A heightened response to the virus is implicated by our mouse model studies. We will determine if more rapid mouse diabetes due to rotavirus requires this heightened response, and if this response is also made by cells from diabetes patients after stimulation with rotavirus or other relevant viruses. These studies are vital to learn how viruses affect type 1 diabetes and devise interventions.
Activation Of The Respiratory Syncytial Virus Fusion Protein

Summary
Respiratory Syncytial Virus (RSV) is the most important viral cause of respiratory tract disease in both infants and the elderly. However, there are few available options for control, whether by vaccination or therapeutic intervention. This proposal investigates the way RSV infects cells. A clearer understanding of the molecular basis of this process should provide potential targets for new drugs that can block this process and new insights for the generation of vaccine candidates.
Solving Delivery Of Gene Therapy For Control Of Human Immunodeficiency Virus Infection

Funding Amount
$765,439.00
Summary
Antiretroviral therapy free control of Human Immunodeficiency Virus (HIV) infection requires control of the viral reservoir. We have a unique approach, aimed at enforcing HIV latency by targeting highly conserved regions in the viral promoter. These constructs completely silence viral transcription for long periods of time. We intend to develop & assess vectors that are specifically targeted to the reservoir and which can enforce viral latency despite immune activation or viral variation.
HIV Phenotypes Important For The Establishment Of Persistent Reservoirs In The Central Nervous System And Which Impact Neurotropism And Neuropathogenesis

Summary
This grant will determine whether or not the CNS is a reservoir for HIV and identify the cellular targets of persistent infection and type of HIV-1 present.
The Dengue Virus Glycoprotein NS1 Binds Cholesterol And Mediates Cellular Activation

Summary
Cholesterol has been shown to play a vital role in the life cycle of many viruses. This project will investigate the basis of dengue virus interaction with this important host molecule and along with investigations of how dengue is able to stimulate host cells, will provide new insights into the way these viruses cause severe disease. Findings from this study will also aid in the development of new drug strategies for dengue and related viruses such as West Nile virus.
Host Metabolism And Responses Contributing To Flavivirus Replication And Pathogenesis

Funding Amount
$592,772.00
Summary
We aim to determine how viruses affect the cells they infect, In particular how they can alter the metabolism and balance of lipids in cells and how this impacts the bodies capability to respond immunologically. We believe that by understanding these basic principles we can target ares fr antiviral therapeutic potential.
Stealth Liposomes And SiRNA For The Treatment Of Respiratory Viral Infections

Funding Amount
$528,793.00
Summary
Respiratory infections caused by Influenza and Respiratory syncytial virus cause significant hospitalisations and deaths within the community. For example, RSV causes around 1000 hospital admissions of young children a year and there is no cure or vaccination. Therapies are limited and toxic. We will develop and test a novel therapy based on gene silencing to specifically target viral genes, and combine this with our novel drug delivery system for better treatment of these diseases.
The Role Of Noncoding Viral RNAs In Flavivirus Infection And Exosomal Signalling
Funder
National Health and Medical Research Council
Funding Amount
$683,447.00
Summary
The application is aimed at investigating the novel role for viral noncoding RNAs in exosomal antiviral signalling and associated outcome of infection with West Nile virus. We will identify host enzymes involved in generation of viral noncoding RNAs, determine which host proteins they interact with and how these interactions determine their incorporation into secreted exosomes to influence outcome of infection.
