Dengue is a serious viral disease that is spread by mosquitoes. Dengue results in hundreds of thousands of children and young adults being hospitalized in Asia every year, and some patients die. There is no vaccine or specific treatment. In this fellowship I will lead a research program that aims provide doctors with the tools to diagnosis and treat dengue more efficiently and to develop a novel biological control to prevent dengue being transmitted by mosquitoes.
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.
A Glycomics Approach Towards Understanding Alphavirus Induced Inflammatory Disease And Discovering Novel Therapeutic Targets

Summary
Alphaviruses are transmitted by mosquitoes and cause a variety of serious human infections. This project investigates how alphaviruses cause disease, with special focus on inflammatory musculoskeletal diseases. The expected outcomes are a better understanding of human viral diseases, with a view to improving prevention and treatment strategies to reduce the disease burden of alphaviruses and related viruses. The research strategy is a world-first, and the institute is an international leader in ....Alphaviruses are transmitted by mosquitoes and cause a variety of serious human infections.

The Role Of Glycans In Arboviral Disease; From Immunomodulation To Glycotherapeutic Treatment Strategies

Funding Amount
$419,180.00
Summary
Dengue and chikungunya viruses are leading causes of emerging mosquito-transmitted (arboviral) disease worldwide. Currently there are no available vaccines or therapeutics making combatting these arboviral diseases one of our most pressing global health challenges. Preliminary evidence shows that glycan recognition is critical for disease immunopathogenesis. This project focuses on the role of viral glycans in arboviral disease with the aim of identifying and expanding on new therapeutic targets
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development
Funder

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.
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.
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.
New Insights Into Viral Inflammatory Disease Mechanisms And Approaches To Therapy

Summary
This fellowship aims to establish how viruses cause disease, including how they evade the immune response to persist and cause disease for prolonged periods. My vision is that knowing how the virus and the immune system interact to determine disease severity will assist in devising new treatments and prevention programs to lessen the impact of viral diseases in Australia and worldwide.
Pathogenic Flaviviruses: Molecular Mechanisms Of Disease, Host Response And Vaccines

Summary
The application is aimed at advancing our understanding of the viral and host processes determining outcome of infection with pathogenic flaviviruses (i.e. West Nile virus) to the level allowing most comprehensive design of effective vaccines and anti-viral drugs. One of the aims is also to develop novel viral delivery vectors for cancer therapy based on self-replicating RNA of an attenuated Australian strain of West Nile virus, Kunjin.
