Summary
Vaccines invoke immune responses that will protect a vaccinated host if they encounter infection. Vaccines can also be deployed to fight cancer. 'Dendritic cells' are the key immune cell responsible for vaccine immunity. While dendritic cells are pivotal to initiating vaccination, little is known about their internal machinery. This research proposal will identify new machinery for dendritic cell vaccine immunity that will serve as therapeutic targets to boost vaccination.
Dendritic cells are essential components of our immune systems. They are located throughout our body and provide the first line of defence against invading microbes. Dendritic cells sense the invader and send out signals to recruit our immune cells to the site of infection. Our research aims to understand how our dendritic cell network is set up and how it functions to promote our immune health.
Dendritic Cells Govern The Balance Between Immunity And Homeostasis To Inhaled Antigen

Summary
The development of better intranasal vaccines hinges on the improved understanding of how the immune response is initiated following vaccine delivery into the upper airways. In this project we will provide fundamental understanding of how immune responses to inhaled antigens are regulated; this considerable conceptual advance will lay the foundation for which new intranasally delivered immunotherapies will ultimately emerge.
Perinatal Microbe-host Interactions Regulate Neonatal Dendritic Cell Development

Summary
Acute lower respiratory tract infections (ALRI) are the leading cause of childhood mortality globally, and increase the risk of chronic lung diseases in later-life. Diverse communities of microorganisms - the microbiome - assemble in infancy and support immune development. In this study, we will explore the relationship between the microbiome and its metabolites, and the expression of an important hormone that regulates the development of the immune system to confer protection against ALRI.
Characterising The Function Of Niche-derived Neuregulin 1 In Colorectal Cancer

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

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.

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.
