Dengue is a viral infection that is transmitted by mosquitoes in tropical regions of the world, including in northern Australia. For doctors who treat dengue patients, a major unmet need is the ability to predict which patients will develop severe complications and need highly specialized supportive care. This proposal will seek to address this unmet need by examining whether markers of human genetic variation can be used to predict those patients at risk of severe dengue.
Harnessing Lipid-reactive Immunity To Combat Mycobacterium Tuberculosis Infection

Funding Amount
$341,458.00
Summary
Critcial to the survival of Mycobacterium tuberculosis, the causative agent of tuberculosis (TB) is its unique waxy (lipid)-rich cell wall. This proposal aims to target components of its cell wall to devlop novel therapeutic strategies. Specifically, the Australian-Singapore alliance will examine how the immune system "sees" lipid based antigens from M. tuberculosis, and then will ultimately use this information towards the devlopment of novel lipid-based vaccines.
Understanding Pathogenicity And Immunity In An Encephalitic Mouse Model Of Hendra Virus Infection

National Health and Medical Research Council
Funding Amount
$572,342.00
Summary
Our understanding of Hendra virus infection and immunity is extremely limited and has been hampered by a lack of appropriate animal models of disease and reagents. This Project will employ a newly-established mouse model to study encephalitis, the most life-threatening manifestation of this infection. We will use unique, state-of-the-art infrastructure and a plethora of mouse-specific reagents to investigate the mechanisms involved in regulating the host response to infection.
Kidney Mesenchymal Stem Cells In Tubular Development, Repair And Turnover

Summary
In Australia, 11.3% of deaths are associated with chronic kidney disease with >$1 billion per annum spent on treating this condition. At present, only dialysis and transplantation are available to treat end stage kidney disease. We have found a kidney stem cell population in both human and mouse that can form new epithelial structures. In this project, we will investigate the normal role played by these kidney stem cells and examine whether they can contribute to kidney regeneration.
Dementias affect a large number of Australians each year with the number of patients expected to triple by 2050. As such, there is need to develop a better model of this debilitating disorder to provide improved treatments. Mesenchymal stem cells, are relatively easy to obtain and grow, and are able to produce the key cell types in the brain. We can use these cells to identify the processes that control the production of brain cells, which will likely provide better treatment of this disease.
How Do Mutations In Autophagy Receptors Cause FTD And ALS?

Funding Amount
$566,966.00
Summary
As cells age the "garbage disposal" process within cells slows down, becoming less functional. In inherited forms of dementia the genes involved often code for damaged proteins that "clog up" the disposal system or directly affect the “garbage men”. These defective garbage men genes include SQSTM1/p62, OPTN, VCP and UBQLN2. We will determine how these defective genes lead to build up of garbage in neuronal cells and how leads to disease.
Self-assembled Hydrogels As A Model For Neurodegeneration

Funding Amount
$594,644.00
Summary
Alzheimer’s disease (AD) is a neurodegenerative disease which currently affects over 340,000 Australians. Often, symptoms of AD are not apparent until the disease is well advanced, limiting chances of successful treatment. In this project, hydrogels made from biocompatible peptides will be used to grow neural cell culture models to study the development of the disease in its early stages. This will help to develop new diagnostic tools for the early detection of AD.
Bioactivated Hierarchical Hydrogels As Zonal Implants For Articular Cartilage Regeneration

Funding Amount
$353,161.00
Summary
Cartilage is frequently damaged, but does not repair on its own, and degenerates in osteoarthritis. Unfortunately, current treatments are also not able to regenerate the structure of normal cartilage and fail to restore joint function long-term. Our project, HydroZONES, brings together expertise from 16 partners to tackle this problem and regenerate cartilage with the appropriate structure to help the millions of people worldwide suffering from cartilage problems such as osteoarthritis.
Bacterial Metabolite Mediated Regulation Of The Immune And Metabolic Systems

Funding Amount
$303,374.00
Summary
The cellular and molecular events that underpin metabolic syndrome diseases, such as diabetes, fatty liver, etc are poorly understood. However recent advances provide new clues. First, the immune system is intimately connected to metabolism. Second, the gut microbiota, and its metabolites such as acetate and butyrate are also important. These metabolites induce epigenetic changes in cells. We will study how metabolites induce molecular changes epigenetically, and how this controls metabolism.
What Is The Effect Of Alzheimer’s Disease On Eye And Can Ocular Changes Be Used As Biomarker For Alzheimer’s Disease?

Funding Amount
$718,002.00
Summary
Visual symptoms are frequent early complaints in Alzheimer’s (AD) patients. Examining eyes can be a simple, specific and inexpensive way to assess and diagnose AD and fill in an urgent need for a viable biomarker. Retina is unique part of central nervous system that can be imaged non-invasively and thus serves as a ‘window to the brain”. Monitoring the eyes will also help prevent negative effects of AD on vision by way of timely intervention, in addition to providing mechanistic insights in AD.
