Funding Amount
$1,035,623.00
Summary
Malaria is a devastating parasitic disease that kills over 400,000 people a year. Antimalarial drugs play a crucial role in helping eradicate malaria but of great concern is that parasites are becoming resistant to current drugs. We are developing drugs that prevent parasites from invading and proliferating in human blood which causes malaria. We are also discovering how the drugs work with the aim of greatly improving their performance towards clinical uptake.
Identification Of Therapy-resistant Cells Driving Relapse In Medulloblastoma From Integrated Spatial Transcriptomics And Tissue Imaging
Funder
National Health and Medical Research Council
Funding Amount
$749,272.00
Summary
Medulloblastoma (MB) is the most common cause of cancer related mortality in children, with relapsed MB nearly a universally fatal event. Relapsed MB can be caused by pre-existing rare cells that escape treatment and continue to evolve. This project will identify the organisation of all cell types within patient derived xenograft models of MB, monitoring how this changes throughout tumour progression and drug treatment. We will identify rare cells responsible for driving recurrence.
Developing Novel Agents To Prevent Tumour Recurrence In Glioblastoma

Funding Amount
$1,089,561.00
Summary
Glioblastoma is a form of brain cancer that is currently incurable. We have discovered that switching-off an enzyme called KDM4 (using 'KDM4 inhibitors') improves chemotherapy outcomes with new drugs also discovered in our laboratory. This project will examine a novel drug combination treatment for glioblastoma patients and generate evidence for initiation of clinical trials. This could initiate a novel therapy that could significantly extend patients' lives.
Gonococcal Vaccine Development Guided By A Cross-protective Meningococcal Vaccine

Funding Amount
$826,490.00
Summary
Neisseria gonorrhoeae, the bacteria responsible for the sexually transmitted infection gonorrhoea, is a significant health problem worldwide. Control of gonorrhoea depends on the development of a vaccine due to the continuing increase of antibiotic resistance and the staggering outcomes of infection, including infertility and increased transmission of HIV. This work will identify vaccine targets and determine the way in which they mediate protection against gonococcal infection.
How A Multidrug Resistant Bacterial Pathogen Has Become Pandemic

Funding Amount
$1,116,544.00
Summary
The pandemic spread of antibiotic resistant E. coli ST131 is a major human health problem. ST131 is the globally dominant cause of urinary tract and bloodstream infections. This project will use advanced genetics and animal infection models to understand the features of ST131 that have fueled its global dominance. The outcomes will unravel the molecular mechanisms that enable ST131 to persist and cause repeat infection, and guide the development of new precision medicine therapeutics.
Virulence Associated Small RNAs In Acinetobacter Baumannii

Funding Amount
$964,148.00
Summary
This proposal aims to understand how a superbug that causes severe infections in hospitalised patients worldwide and is known to be resistant to almost all available antibiotics, causes disease. We then plan on using this information to guide the development of a new type of therapy to treat this severe infection.
Novel Antibiotics That Harness Innate Immunity To Overcome Multi-drug Resistant S. Aureus

Funding Amount
$872,355.00
Summary
Controlling infection with antibiotics is essential in medicine. However, bacterial resistance to antibiotics is growing rapidly. Here, we propose new strategies to treat multi-drug resistant Staphylococcus aureus by combining existing clinical antibiotics with either a targetted immune response or by removing the ability of bacteria to hide from our immune system. These novel approaches will allow us to overcome infections caused by resistant bacteria, which are a serious and growing problem.
Plasma Activated Hydrogel Therapy For Combatting Antimicrobial Resistance In Chronic Wounds
Funder
National Health and Medical Research Council
Funding Amount
$755,023.00
Summary
The aim is to advance wound care using electrical ionised gas discharge (plasma) to deliver antimicrobial and healing agents through tailored hydrogel dressings into wounds. The technology will be configured for real-world wounds and clinical settings and its antimicrobial delivery system will be optimised to eradicate all wound pathogens and prevent re-infection. The technology has potential to revolutionise chronic wound care and alleviate the growing problem of antimicrobial resistance.
Relaxin Receptor Structural Determination To Aid Therapeutic Development

Funding Amount
$1,249,114.00
Summary
The receptor for the peptide hormone relaxin, RXFP1, is being targeted by numerous drug companies for the treatment of cardiovascular disease. However, the lack of molecular detail of how relaxin binds and activates RXFP1 is hindering new drug development. We will determine the structure of the complex of relaxin bound to RXFP1 and the mechanism by which this activates cells. The knowledge gained will aid in the design of new drugs targeting RXFP1 for the treatment of cardiovascular disease.
Molecular Characterisation Of The DBHS Proteins In Telomerase Assembly
Funder
National Health and Medical Research Council
Funding Amount
$686,246.00
Summary
Telomerase is an enzyme that is active in over 90% of cancers. Telomerase activity allows cancer cells to divide an indefinite number of times. We have identified a novel role for the DBHS protein family in regulating telomerase activity. We aim to investigate the mechanisms by which these proteins function to assemble and transport telomerase to its site of action in the cell. We then aim to develop chemical inhibitors of these proteins, and test their utility in preventing cancer cell growth.
