Summary
Antibiotic mono-therapies are increasingly ineffective for hard-to-treat bacterial infections, forcing clinicians to rely on combinations of antibiotics. Our project has identified compounds that have weak to no antimicrobial potency in their own right, yet when combined with an existing antibiotic they potentiate its activity and restore its ability to treat resistant infections. These antibiotic potentiators are exciting alternatives to current therapies with reduced risk of induced resistance
Targeting Pathogenic TAR DNA-binding Protein 43 To Treat Frontotemporal Dementia And Motor Neuron Disease

Funding Amount
$687,444.00
Summary
Frontotemporal dementia and motor neuron Disease are rapidly progressive and fatal neurodegenerative diseases that affect people in their prime. Poor understanding of the processes that lead to these diseases have slowed drug development. Through innovative experimental design, we aim to decipher a novel disease mechanism that involves specific molecular interactions and translate these findings into new therapies for the diseases.
Gamma Delta T Cells: The Fourth Player In CD8 T Cell Immunity

Summary
The immune systems of animals have evolved complex but effective mechanisms to protect against infection with intracellular pathogens. This requires that T cells can distinguish uninfected cells from those harbouring pathogens. This is achieved via recognition of pathogen-derived molecules, which activate the immune system to recognise and fight the pathogen. We have identified a crucial role for a gamma delta T cells in this process, making them essential sentinels of intracellular infection.
Nanoengineered Bioelectronic Systems For All-Optical Control Of Neuron Growth And Stimulation

Summary
Nerve cells are the primary signal carriers of the human body. When they cease to function normally, our bodies ability to function and sense the physical world is influenced catastrophically. We will develop a new bioelectronic system made by printing clever inks that can artificially stimulate nerve cells without the typical requirements for invasive metal electrodes or external power. These new scientific advances will revolutionize nerve cell repair and treatment of neurological disorders.
Characterising The Function Of Niche-derived Neuregulin 1 In Colorectal Cancer

Funding Amount
$994,246.00
Summary
Colorectal cancer affects thousands of Australians each year. A specialised cell population, named cancer stem cells, continuously produces new tumour cells. Defining mechanisms controlling the behaviour of these unique cells is critical to develop new drugs. We have identified that Neuregulin-1 is a key factor that enhances the action of cancer stem cells. We aim to study how colorectal cancer is mediated and whether targeting Neuregulin-1 is a promising therapeutic option.
Characterisation And Targeting T Cellular Metabolism To Improve Control Of Chronic Viral Infections

Summary
CD8+ T cells are the frontline warriors of our immune system that can eliminate infected or cancerous cells. However, diseases caused by overwhelming viral infections are associated with widespread impairments in immunity and cellular metabolism. Here, we propose to examine molecular pathways involved in cellular metabolism that could be utilized to improve therapies against viral infection and cancer.
Improving Clinical Outcomes Of Antimicrobial Resistant Infections With A Drug-free Intervention

Funding Amount
$999,581.00
Summary
Superbugs, or antimicrobial-resistant pathogens, cause recurring infections and non-healing wounds after surgery as existing therapies fail to effectively kill them. We will develop a medical device to fight superbugs with UV light that is effective against bacteria and fungi without causing harm to human cells. This could eradicate superbugs at infection sites, aid wound healing and actively improve health outcomes after surgery.
Hijacking A Death Switch In Pancreatic And Lung Cancer Cells To Develop A Novel Therapy

Funding Amount
$738,947.00
Summary
Pancreatic (PC) and lung (LC) cancer have a high mortality rate and poor response to current treatments. We have identified a protein whose inhibition in both PC and LC cells sensitises them to a cancer-cell specific therapy called TRAIL and switches signals that normally promote tumour growth into tumour death signals. This project aims to develop a novel therapeutic that inhibits our target and delivers TRAIL to PC and LC tumours, and could potentially improve survival for PC and LC patients.
Therapeutic Induction Of Tertiary Lymph Nodes In Cancer

Summary
Immunotherapy has been an important recent advance in cancer treatment by using the body's own immune cells to fight cancer. Although there have been unprecedented dramatic results, not all patients benefit, and most benefits are temporary. The cellular environment in which cancers are embedded is crucial for controlling treatment success. We aim to apply novel 'precision' therapies to this environment to expose the cancer and enable attack by immune cells for improved immunotherapy.
Developing Smart Nanomedicine To Enable Advanced Diagnosis And Stimuli-responsive Treatment For Atherosclerosis And Thrombosis

Funding Amount
$523,342.00
Summary
The early detection and accurate characterization of life-threatening diseases such as cardiovascular diseases are critical to the design of treatment. A therapeutic approach that provides an efficient treatment with minimal side-effects is highly desired by both patients and healthcare systems. This project aims to develop smart nanomedicine with incorporated diagnostic sensor and external stimuli-responsive treatment mechanisms for cardiovascular diseases.
