Understanding Virulence Of Invasive Staphylococcus Aureus

Funding Amount
$772,711.00
Summary
Staph aureus (Golden staph) is a major cause of disease in humans. In this project we will use state-of-the-art molecular biology and genomics to fully understand the mechanisms of virulence in this pathogen. This information will inform future approaches to development of therapeutics, as well as the use of genomics in clinical microbiology and disease management.
Membrane Attachment And Components Of The Ca2+ -triggered Release Mechanism
Funder

Funding Amount
$386,498.00
Summary
Understanding and harnessing the fundamental cellular process of secretion will provide a wealth of new approaches to addressing problems associated with aging & disorders that are major health care burdens (e.g. neurodegeneration & diabetes). Understanding the vesicle docked state, and the contributions of different molecular components to the release process provides for unique insights into the underlying molecular mechanisms, thereby enabling safe, targeted control of this critical process.
Understanding The Role Of Caspase-2 In Cellular Stress Response And Ageing

Funding Amount
$918,517.00
Summary
This project builds upon our recent findings showing that a protein, called caspase-2, is involved in protecting against oxidative damage and ageing in a mouse model. We propose to carry out further studies to fully understand how caspase-2 regulates cell’s response to oxidative stress. Such studies will be critical in assessing if caspase-2 or its substrates are useful targets for drugs to treat diseases that may arise due to cell’s inability to properly respond to oxidative damage.
Acinetobacter Baumannii Virulence From A Regulatory Perspective: The Role Of Two Component Signal Transduction Systems
Funder
National Health and Medical Research Council
Funding Amount
$608,731.00
Summary
Acinetobacter baumannii is becoming a significant pathogen in the hospital and more recently in the community. It is very resistant to removal from surfaces and upon entering the host is almost impossible to treat with currently available antibiotics. It causes a wide range of disease states from wound infections and pneumonia to bacteraemia; little is known of this process. This research will increase our understanding of the disease process, providing possible treatment options in the future.
Targeting MiRNA To Inhibit Leukocyte Differentiation: A Novel Anti-inflammatory Approach For The Treatment Of Asthma
Funder
National Health and Medical Research Council
Funding Amount
$601,386.00
Summary
In asthma, the symptoms are caused by an allergic reaction in the lung and the production of inflammatory cells whose maturation is guided by tiny molecules called “microRNAs”. The critical microRNAs will be identified and strategies to block their function developed and tested for their ability to inhibit allergic inflammation to evaluate this approach as a new treatment for asthma.
Delayed Radial Glial Maturation Linked To NFI Deficiency As An Underlying Cause Of Cortical Defects In Humans And Mice
Funder
National Health and Medical Research Council
Funding Amount
$801,979.00
Summary
The timely generation of neurons and glia is important for brain development and consequently brain function throughout life. Nuclear factor I (NFI) genes are important for regulating the production of neurons and glia, and people with disrupted NFI genes have severe cognitive and motor deficits. Using human genetic data and mouse models, we will analyse how disrupting these genes affects brain development, and changes the overall structure and wiring of the cerebral cortex as well as behaviour.
Understanding The Mechanisms Of Steroid Resistant Inflammatory Pathways In Mouse Models Of Asthma: Potential New Treatment Approaches
Funder
National Health and Medical Research Council
Funding Amount
$523,694.00
Summary
Steroids are used to treat asthma but some patients are resistant to therapy, and there is no effective treatment. Such patients suffer greater morbidity and mortality, and the heath care cost for clinical management is a significant economic burden. In this project we will obtain a better understanding of the mechanisms that regulate steroid-resistant components of disease, which control inflammation and narrowing of the airway. These studies will be central to the development of new therapies.
The Role Of EphA2 Signalling And Environmental Modifiers In Cataract.
Funder
National Health and Medical Research Council
Funding Amount
$591,547.00
Summary
In cataract the clear lens in the eye becomes opaque causing blindness. Cataract is very common in the elderly, but is rarely also seen in babies and children. In babies certain gene defects, and in the elderly the genes and environmental factors contribute to cataract. The EPHA2 gene causes cataract in both young and old people. This project aims to understand how EPHA2 and other related genes cause cataract in young and old people, to prevent, delay or improve its treatment in the future.
High-Throughput Discovery Of Synergistic Drug Combinations For Metastatic Colorectal Cancer
Funder
National Health and Medical Research Council
Funding Amount
$1,526,568.00
Summary
Treatment outcomes for patients with metastatic bowel cancer remain poor, with most tumours developing resistance within 24 months. A key problem is that cancers are genetically diverse, with some cells inevitably resistant to any given treatment. This study aims to discover effective drug combinations targeting distinct essential tumour cell functions through robotics-based pairwise testing of known drugs on bowel cancer cell lines representing the genetic diversity of the disease.
How Do Anaesthetics Work? A Rational Basis For Safer General Anaesthesia.
Funder
National Health and Medical Research Council
Funding Amount
$592,008.00
Summary
General anaesthetics are a mainstay of modern medicine, but have a small safety margin, requiring skilled anaesthetists for their safe use. There is growing evidence that general anaesthetic exposure may have long-term effects on brain function in both newborns and the elderly. This project will provide a detailed molecular description of anaesthetic action and specificity. It will provide the basis for designing new anaesthetics that are safer, both immediately and for long-term brain function.
