Summary
Hendravirus outbreaks have become frequent and 7 human cases have been reported, this has resulted in 4 deaths. Currently we have no treatment options. Researchers at Griffith University and the CSIRO have developed a new treatment that attacks the virus by turning off the viral genes at the site of infection. The plan is to treat patients soon after infection to slow or stop the virus and allow patients to recover naturally from this highly lethal disease.

Summary
Rhinovirus (RV) infections are the major cause of virus induced asthma attacks, causing significant morbidity and mortality. Asthma & asthma exacerbations are increasing worldwide with new strategies urgently needed to reduce RV-associated disease. We aim to build on our substantive new data, using cutting edge technology to identify new targets for novel asthma therapies.
Stealth Liposomes And SiRNA For The Treatment Of Respiratory Viral Infections

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.
Viral And Host Factors Determining Outcome Of Zika Virus Infection

Summary
The proposal aims at identifying viral and host factors determining outcomes of infection with Zika virus, a significant mosquito-transmitted pathogen associated with debilitating neurological pathology in new-borne babies from mothers infected during pregnancy. We will use cutting edge methodologies and infections models to bring our understanding of Zika virus infection to unprecedented level. The results could also facilitate identification of targets for effective anti-viral therapy.
Host Genes Controlling Flavivirus Infection: New Insights And Application For Developing Highly Effective Kunjin Replicon-based Ebola Vaccine

Funding Amount
$736,995.00
Summary
The applications is aimed at identifying new host genes controlling infection with West Nile virus and other medically important flaviviruses such as dengue and Japanese encephalitis. For this, we will use novel in vivo RNAi screening approach with virus libraries encoding artificial microRNAs (amirs) targeting whole mouse genome. We will then apply amiR technology to produce highly effective Kujniin replicon-based Ebola vaccine candidate that has shown promising results in trails in primates.
HIV-1 Transcriptional Gene Silencing By Promoter Targeted Si/shRNAs: Uncovering Mechanisms, Optimising Delivery Systems, Assessing In Vivo Efficacy.

Summary
Current therapy for HIV is effective but must be taken for life. If therapy is stopped the virus comes back immediately from reservoirs not affected by current drugs. These fluctuating levels of virus are associated with increased illness and death. We are exploring a method of inducing prolonged viral latency using short double stranded RNA molecules. We propose to understand the mechanism of action of these possible therapeutics and to develop these constructs towards use in clinical trials.
Wolbachia And West Nile Virus In Mosquitoes: Friends Or Foes?

Summary
Mosquito-borne viruses pose a great risk to human and animal health. Presence of compentent vectors of several viruses in Australia indicates vulnerability of Australia’s biosecurity. This project will define the mechanisms of inhibition of virus replication in mosquitoes by a symbiotic bacterium which can be utilized in virus inhibition.
Role Of Flavivirus-encoded Small Regulatory RNAs In Virus-mosquito Vector Interactions

Summary
Mosquito-borne diseases are major threats to human health. MicroRNAs are small non-coding ribonucleic acids (RNAs) that play important roles in development, cancer, apoptosis, immunity, longevity, and viral infections. We propose to identify the regulatory microRNAs from flaviviruses and establish their potential function in vector-arboviruses interactions. The project will put Australia at the forefront of research in the most rapidly developing area of microRNA research.
The Role Of Noncoding Subgenomic Flavivirus RNA In Virus-host Interactions

Summary
Flaviviruses such as Dengue, Japanese encephalitis , and West Nile are major human pathogens causing more than 50 million infections per year. Elements in viral genome responsible for pathogenesis of these viruses are not well defined. Recently we have identified a unique for these viruses noncoding subgenomic flavivirus RNA (sfRNA) and showed that it is contributing to viral pathogenesis. In this proposal we aim to determine mechanisms by which sfRNA facilitates viral pathogenesis.
