Summary
Abnormal subcellular lipid distribution is associated with a number of common diseases including cancer, cardiovascular disease, and Alzheimer’s disease. The overall aim of this proposal is to identify and characterize new molecules that regulate the transport of lipids between different cell membranes. Results from the proposed studies will help developing novel therapeutic agents against common human diseases.
The cell is the building block of life. This proposal focusses on the surface of the cell, the plasma membrane, and specialised structures called caveolae that are an abundant feature of animal cells. Altered caveolae are a feature of many human disease conditions. In this proposal we will address the function of caveolae. We will test the idea that proteins are released from caveolae into the cell when cells are stressed forming a novel signalling pathway disrupted in disease.

Summary
This research proposal is to investigate the molecular mechanism and function of a blood serum protein, histidine-rich glycoprotein (HRG), in protecting against tissue injury caused by inflammation and infection. HRG has been implicated in controlling important aspects of tissue injury by aiding removal of dead cells and pathogens. Understanding the role of HRG in these disease settings may allow the development of approaches for the treatment of inflammatory, autoimmune and infectious disease.
Regulation Of The Signalling Efficiency Of The T Cell Antigen Receptor

Summary
An immune response starts with activation of the T cell antigen receptor (TCR). How T cell receptor signalling begins, however, is not well understood. We have developed a novel imaging approach that allows us to directly observe what happens after an antigen binds to the receptor. The research will provide mechanistic insights into how T cells sense and discriminate antigens. This knowledge will aid the development of cancer immunotherapies and vaccines.
Delineating The Mechanism Of Amyloid Beta Toxicity

Summary
Alzheimer’s disease and beta amyloid toxicity: Alzheimer’s disease (AD) is the most common form of dementia and is characterized by progressive memory loss, confusion, and cognitive deficits. In 2011, an estimated 269,000 Australians are currently living with dementia and without a significant medical breakthrough soon, it is anticipated that this will rise to about 981,000 by 2050
Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System

Funding Amount
$593,742.00
Summary
Radiation therapy is a highly effective cancer treatment with extremely high doses delivered using very complex treatment machines. Unfortunately errors have occurred resulting in cases of patient death and mistreatment. We have developed a novel method to assess the treatment delivery in real-time to prevent errors. The method uses imaging devices that are already present on the treatment machine meaning that this method could have a major impact on patient safety in modern radiation therapy.
Design And Application Of New Nanomaterials Theranostic Platforms For Targeted Treatment Of Cancer

Funding Amount
$530,626.00
Summary
The project aims to develop intelligent drugs that attract to malignant tumors like magnets. These powerful, next-generation chemotherapy drugs seek out cancerous cells, allowing physicians to see exactly where tumours lie. Nanoparticles inside the drugs then switch on upon contact with X-ray radiation beams. This new method, which can diagnose, deliver targeted therapy and monitor the response to therapy all at the same time, would reduce the amount of radiation needed to kill cancer cells.
Fast And Efficient Assessment Of Dose In Small Targets In Radiotherapy: Effect Of Motion In Clinical Research And Implementation Of Dynamic Therapy
Funder
National Health and Medical Research Council
Funding Amount
$501,265.00
Summary
The continued progress of radiation therapy for cancer patients has been driven by technology developments that have increased the complexity of radiation delivery, but has come at the cost of increased potential for errors in radiation planning and delivery. The aim of this project is to implement an instrument for verification of treatment delivered to organs with large variation of shape and position due to respiration. This will enhance treatment outcome and patient quality of life.
Optimising Radiation Therapy Delivery For Cancer Patients Using Daily Image Guidance To Maximize Cure And Reduce Normal Tissue Side Effects
Funder

Funding Amount
$510,968.00
Summary
When using radiotherapy to kill tumours, the radiation beams need to be targeted at the tumour, plus a margin of error around it to ensure that it receives sufficient dose despite uncertainties in its exact location relative to reference points used for beam alignment. Advanced statistical modelling techniques applied to data collected from patients will be used to determine the optimal margin width for individual patients to maximise cancer cure while minimising normal tissue side effects.
Cancer Radiotherapy 2020: Accounting For Tumour Deformation In Real Time To Improve Treatment Outcome
Funder
National Health and Medical Research Council
Funding Amount
$371,616.00
Summary
Tumours in lung and prostate cancer change shape during radiotherapy treatment. This is not accounted for in current care, compromising the therapeutic efficacy. We will develop the first radiotherapy system that can adjust the radiation beam in real time to follow the changing tumour shape. We will assess the performance of the system and quantify the clinical benefit. It is expected that clinical implementation of this technique will improve the cure rates and decrease the treatment toxicity.
