The Interplay Between Viperin, Peroxisomes And The Cellular Innate Antiviral Response

Funding Amount
$556,127.00
Summary
Infection with a virus initiates a cellular antiviral response that attempts to limit viral replication, however how this response is regulated is not well understood. In this proposal we will investigate a cellular protein (viperin) that can regulate this process by interaction with peroxisomes to amplify the antiviral response. This work will provide possible targets for therapeutic manipulation of the innate immune response that will be applicable to a wide range of viral infections.
Signalling Pathways And Fungal Virulence – The Inositol Polyphosphate Kinase Pathway In Cryptococcus Neoformans

Funding Amount
$545,189.00
Summary
Bloodstream fungal infections kill millions of people per year world-wide and are costly to treat. A potentially fruitful strategy for developing new, urgently-needed drugs to fight these infections, is to target signalling pathways, which in fungi, are essential for establishing infection. This proposal investigates how one such pathway, the inositolpolyphosphate kinase pathway, allows fungi to establish infection and will determine which components are suitable targets for drug development.
Targeting Drug-Resistance In Paediatric Acute Lymphoblastic Leukaemia

Funding Amount
$649,048.00
Summary
Leukaemia is the most common type of cancer in children but resistance to therapy continues to be a significant problem. This project will investigate the biology of drug-resistance and relapse using a mouse model that replicates the human disease. We hope to identify novel therapeutic targets that can be used in combination with existing therapies to improve outcomes in this disease, particularly for patients that develop drug-resistance such as those at the time of relapse.
Mechanism Of Anoxic Iron Acquisition In Pathogenic Bacteria

Funding Amount
$536,280.00
Summary
All organisms require iron for their survival, including all bacterial species. Bacterial pathogens growing in anaerobic environments, such as in our gut, gum, or tissue, sequester iron through the divalent iron transporter FeoB. We aim to divulge the mechanism of iron transport through FeoB by structural and functional studies, and thus provide a scaffold for a non-conventional antimicrobial target.
An International Clinical Trial To Evaluate New Therapies To Improve Survival Of Children With Relapsed Acute Lymphoblastic Leukaemia
Funder
National Health and Medical Research Council
Funding Amount
$1,567,500.00
Summary
Children who relapse with childhood leukaemia have only a 50% chance of being alive after 5 years. We will participate in a new international trial involving most European and all Australian and New Zealand childhood oncology centres, to test the effectiveness of promising new treatments and to perform biological studies which should enable doctors in future to pick the best treatment for each of these patients.
Prion-like Behaviour In Immunity: Super-sized Signalling Platforms?
Funder
National Health and Medical Research Council
Funding Amount
$611,995.00
Summary
Prions have been mostly associated with pathologies but recent discoveries show that prion-like behaviour may be beneficial, enhancing our immune response for example. To test this, we want to systematically explore all human proteins involved in the defence against pathogens, find new prion-like trends and probe their role in the innate immune response.
The Structural Basis For Glutamate Transporter Function
Funder
National Health and Medical Research Council
Funding Amount
$373,144.00
Summary
Glutamate transporters are vacuum cleaners in the brain that suck the neurotransmitter glutamate into cells. When the glutamate vacuum breaks down or becomes blocked, glutamate levels outside cells increase, leading to cell death in the brain. This process underlies the damage in many brain diseases including Alzheimer’s disease and stroke. The aim of this project is to understand the mechanism of the glutamate vacuum cleaner so we can develop therapeutics to fix it when it breaks down.
