This project will develop a smart bone healing gel to bridge fragments of bone defects leading to stem cell recruitment, reduced inflammation, and blood supply for fracture healing. The design of the smart bone healing gel is based on the structures and properties of functional tissue healing hematoma in wound healing.
Improving Kidney Transplant Outcomes Using Normothermic Machine Perfusion

Funding Amount
$778,232.00
Summary
Kidneys donated for transplantation are at risk of damage that prevent the organ from working and reduce its lifespan. Normothermic machine perfusion is a device that can circulate oxygenated blood at normal body temperature through a donor kidney prior to transplantation. In doing so it is able to resuscitate the kidney and prevent injury. We will determine how machine perfusion achieves this remarkable effect and investigate new treatments for kidney injury.
Cells recycle old components using a system called the proteasome. Some people are born without parts of the proteasome, and they suffer from a disease associated with inflammation. We have identified the molecular trigger for this inflammation. Our findings are also relevant for patients being treated with proteasome inhibitors. In some of these diseases, such as lupus, inflammation can be a side-effect of proteasome inhibitor therapy, and we can now reduce this and make the treatments safer.
HARNESSING T CELL QUALITY FOR PANDEMIC PREPAREDNESS

Funding Amount
$503,146.00
Summary
Developing highly effective vaccines is critical to rapidly combat global pandemics. To generate a protective antibody response against novel viruses, a vaccine must elicit a targeted B cell response supported by effective CD4 T cell help. We propose that existing CD4 T cell memory can be harnessed to rapidly and effectively support B cell responses to novel vaccine candidates. This work will contribute to pandemic preparedness strategies and improve the development pathway for new vaccines.
Biopsychosocial Risk And Protective Factors Of Trauma Exposure In First Responders: A Longitudinal Investigation
Funder
National Health and Medical Research Council
Funding Amount
$1,137,427.00
Summary
Investigating individual differences in response to stress is crucial to improving both psychotherapy and pharmacotherapy for individuals at high risk for exposure to trauma. This world-first project will investigate pre and post-trauma psychological and biological trajectories associated with health outcomes in first-responders, contributing significantly towards our fundamental understanding of the biology of risk and resilience to trauma exposure, a key health issue.
Targeting Antimicrobial Resistance And Host Immune Evasion In Staphylococcus Aureus
Funder
National Health and Medical Research Council
Funding Amount
$892,831.00
Summary
This project aims to show how one of the most important human superbugs, Staphylococcus aureus (Golden staph), develops resistance to one of our most important last-line antibiotics and the immune system to cause life-threatening infections. Our work will also investigate and test new treatment strategies for this common and challenging human pathogen.
Determining Immune Dynamics During Controlled Primary Infection In Humans

National Health and Medical Research Council
Funding Amount
$579,823.00
Summary
T cells are critical to human health being our second and last line against infectious disease and cancer. However, we know very little about how this hugely complex immune compartment operates during primary challenge with infectious disease. This project will use new technologies to resolve this immune compartment to high detail during the days, weeks and years following controlled infection in human volunteers.
Deadly Commute - Targeting The Trafficking Mechanisms That Licence Inflammatory Cell Death

Summary
MLKL is a protein naturally found inside cells. MLKL is activated by inflammation. Once activated, MLKL relocates to the outer periphery of cells and kills them. Gut cells are especially vulnerable to death-by-MLKL and this problem causes Inflammatory Bowel Disease. Using cutting edge microscopy, we have discovered how MLKL moves to the periphery of cells prior to killing them. We will test if blocking this movement of MLKL to the cell periphery stops gut death and Inflammatory Bowel Disease.
