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.
This study aims to elucidate central pathways which can be manipulated to drive the storage of excess energy away from fat and instead directing it into the production of bone mass. Having identified leptin-responsive NPY neurons as important in the control of energy partitioning, we will focus on manipulating these neurons in the hypothalamus using innovative technology to alter body composition. This research has the potential to result in novel treatments for obesity and osteoporosis.
Sickle Cell Disease was the first molecular disease described in man, and is the most prevalent. In some African countries, India and the Middle East, up to 20% of the population carry the sickle gene mutation. In developing countries, 90% of children die before 5 years of age. In developed countries, patients suffer a lifetime of chronic pain and die ~20 years early. We will employ new gene editing approaches to repair the mutation or recruit fetal hemoglobin to cure SCD in human samples.
Characterising The Function Of Niche-derived Neuregulin 1 In Colorectal Cancer

Funding Amount

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.
Molecular Regulators Of Adaptive Immunity To Overwhelming Viral Infections

Funding Amount
$786,898.00
Summary
Diseases caused by overwhelming viral infections, such as COVID-19, are associated with widespread impairments in immunity and constitute a major burden to human health. We have discovered that the molecule c-Myb is essential for the maintenance of immunity during chronic infection. In order to lay the foundations for novel and innovative anti-viral therapies, this project will dissect the molecular pathways regulated by c-Myb that maintain immunity during severe or chronic infection.
Are Oligodendrocytes The Missing Link In Amyotrophic Lateral Sclerosis Pathogenesis?

Summary
Amyotrophic Lateral Sclerosis (ALS) is a debilitating and progressive neurodegenerative disease. Recent research suggests important cells of the central nervous system called glia play a role in disease onset and progression. We are interested in a type of glia called oligodendrocytes; they are crucial for supporting the survival of the cells that die in ALS. Only through understanding the underlying biology of ALS can we aim to identify effective therapies that will benefit patients.
Bring Out Your Dead - How Does Defective Apoptotic Cell Clearance By Tingible Body Macrophages Lead To The Activation Of Self-reactive B Cells In SLE?

Summary
Good housekeeping is critical to the day-to-day running of the immune system. In the case of the germinal centre, a key structure where plasma cells are generated, the ability to clear away dead and dying cells is critical because failure to do so can lead to the spillover of cellular waste and debris into the follicle where they can activate harmful B cells to make autoantibodies and cause disease. Understanding how this happens can lead to new ways to target and treat autoimmune diseases.
Defining A New Player In Atherosclerosis: The Role Of Adventitial Haemangioblasts As An Outside-in Driver Of Plaque Growth And Stability.

Funding Amount
$728,005.00
Summary
As the underlying cause of heart attack, atherosclerosis is a leading cause of death worldwide. New approaches to treatment are desperately needed and this requires a better understanding of how atherosclerotic plaques form in arteries. This project studies a new population of stem cells that we have discovered in the outer layer of arteries, to determine how they cause plaques to form, so that we can develop new therapies that target these stem cells to more effectively treat atherosclerosis.
We are studying human amnion epithelial cells (AECs) as a new therapy for stroke. Here if we find the protective effects of AECs are unaffected by a 'clot-buster' drug,we will broaden our planned Phase II trial of AECs to include patients that have received clot lysis therapy. Further, as we suspect that AECs exert their effects via release of nanoparticles called 'exosomes', we will test whether exosomes given intravenously or intranasally are similarly protective.
Using Immunological Principles To Inform Malaria Vaccine Design

Funding Amount
$577,763.00
Summary
Malaria kills ~420,000 people each year worldwide. While a vaccine does exist, efficacy is poor and protection wanes rapidly. We have made breakthroughs in understanding the immune response to malaria that allow us to design a new generation of malaria vaccines. Based on this we aim to generate a vaccine that induces sustained levels of high-quality antibodies targeting multiple targets on the parasite and so can provide sustained long-term protection.
