Exploring the immunomodulatory potential of Natural Killer T cells. Natural Killer T cells (NKT cells) are an innate-like population of T cells that recognise a range of lipid based antigens when bound to the antigen-presenting molecule, CD1d. Once activated, NKT cells rapidly secrete a variety of cytokines. This project, in partnership with Vaxine Pty Ltd, aims to gain a basic understanding of NKT recognition of lipids and NKT cell activation by lipids. The project aims to use a combination of ....Exploring the immunomodulatory potential of Natural Killer T cells.

Enhanced multivalent vaccine responses using a novel vaccine vector system. Enhanced multivalent vaccine responses using a novel vaccine vector system. This project aims to develop a multicomponent vaccine system to deliver equal effectiveness against several disease targets in a single administration. New and innovative vaccine design strategies incorporating economical commercial production processes are urgently needed for new and existing human and animal health applications. A vaccine capab ....Enhanced multivalent vaccine responses using a novel vaccine vector system. Enhanced multivalent vaccine responses using a novel vaccine vector system. This project aims to develop a multicomponent vaccine system to deliver equal effectiveness against several disease targets in a single administration. New and innovative vaccine design strategies incorporating economical commercial production processes are urgently needed for new and existing human and animal health applications. A vaccine capable of targeting multiple diseases by a single injection is an obvious way to expedite future vaccine development and deployment. However, the recipient’s immune system can repress equivalent responses to these multicomponent vaccines. This project’s research is expected to address these problems, and underpin the future commercial development of this vaccine platform.Read moreRead less
The development of a potent new passive immunotherapeutic for the treatment and prevention of bacterial sepsis and septic shock. Bacterial sepsis and septic shock is a leading cause of death in hospital intensive care units and represents a significant public health burden. By developing a new passive immunotherapeutic regimen to treat and prevent bacterial sepsis and septic shock, the project aims to reverse the significant mortality and morbidity associated with this condition.
Ecology, morphology and the diversification of Australian lizards. This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification. The project expects to shed light ....Ecology, morphology and the diversification of Australian lizards. This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification. The project expects to shed light on the evolution of Australia’s most diverse vertebrate lineage, and provide comparative data with which to interpret the lizard fossil record in Australia, and the range declines and relative extinction risks of native lizard species.Read moreRead less
Mechanisms controlling enteroendocrine hormone secretion in human duodenum. This project aims to gain a deeper understanding of nutrient sensing pathways present in enteroendocrine cells within the human intestine. These cells control digestive function, blood glucose levels and food intake and are thus critical to digestion. This project will endeavour to be the first to assess the biology of human enteroendocrine cells and will use innovative approaches to deeply assess function from the level ....Mechanisms controlling enteroendocrine hormone secretion in human duodenum.

These cells control digestive function, blood glucose levels and food intake and are thus critical to digestion. This project will endeavour to be the first to assess the biology of human enteroendocrine cells and will use innovative approaches to deeply assess function from the level of the individual to isolated enteroendocrine cells.Read moreRead less
Determining the regulation of vitamin D metabolism. The proposed project will lead to a better understanding of factors that influence the biological function of vitamin D. This will impact in several areas of human health and will provide new avenues for the development of preventative approaches and treatment of cancer. This project is based on the use of 'Frontier Technologies' that will be applied to elucidate basic biological questions.
The mechanisms and roles of receptor clustering in cell activation and wound healing by growth factors. Growth factors regulate cell proliferation, migration and differentation by interaction with receptors. Such receptors are usually localized at the cell surface, and require intracellular transduction systems to transmit the signal to the cell interior. We have recently shown the hormone-induced clustering of heterologous hormone receptors in cells, and that this occurs with the co-clustering ....The mechanisms and roles of receptor clustering in cell activation and wound healing by growth factors. Growth factors regulate cell proliferation, migration and differentation by interaction with receptors. Such receptors are usually localized at the cell surface, and require intracellular transduction systems to transmit the signal to the cell interior. We have recently shown the hormone-induced clustering of heterologous hormone receptors in cells, and that this occurs with the co-clustering of downstream signalling molecules at sites of engagement with the extracellular matrix. In addition, we have found that cells presented with an extracellular matrix respond better to subsequent growth factor stimulation. The project aims to determine the cellular mechanisms underlying receptor clustering and the basis of the receptor-extracellular matrix interaction. This will enhance our understanding of growth factor function in a number of conditions, including wound healing. We will extend our in vitro results to the animal model to define parameters for enhanced wound repair.Read moreRead less
Differentiation of Cord Blood Stem cells into Thymus (T) cells with regulatory phenotype and function. This project will develop technologies for a stem cell therapy platform based on cord blood stem cells, to enable treatment of autoimmune diseases or transplants. Building on the University of Adelaide's frontier demonstration of differentiation of regulatory Thymus (T) cells from cord blood stem cells, the project will develop techniques to expand the numbers of T cells generated. This has the ....Differentiation of Cord Blood Stem cells into Thymus (T) cells with regulatory phenotype and function. This project will develop technologies for a stem cell therapy platform based on cord blood stem cells, to enable treatment of autoimmune diseases or transplants. Building on the University of Adelaide's frontier demonstration of differentiation of regulatory Thymus (T) cells from cord blood stem cells, the project will develop techniques to expand the numbers of T cells generated. This has the potential to maintain Australia's lead in differentiation of cord blood stem cells and to provide a significant breakthrough in potential treatments of autoimmune diseases (e.g. type 1 diabetes) or transplantation. These diseases affect both a healthy start to life and healthy ageing, and an Australian invention to treat or cure them would have global impact.Read moreRead less
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
