Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity ....Studies on the regulation of the pro-apoptotic protein Bim in mammalian development and cancer. This project is aimed at understanding the regulation of a gene, which is a tumour suppressor and is often mutated or down regulated in many different forms of cancers. A better understanding of how this gene works may eventually lead to better therapeutics to treat these cancers. This is relevant in the Australian context given that our aging population and obesity epidemics (the link between obesity, insulin resistance and various forms of cancers is well established) are leading to a rapid increase in new cancer cases, thus driving a rapid increase in demand for better treatments. This is particularly relevant in Indigenous health where obesity is on the rise following the transition from a traditional to an urban lifestyle.Read moreRead less

An investigation into CD1a, a versatile antigen-presenting molecule. This project aims to investigate how T lymphocytes are activated by lipids presented by the skin-associated antigen-presenting molecule, CD1a. Using X-ray crystallography and cellular immunology, we will provide fundamental insight into this poorly understood immunological axis. We will determine the molecular basis for how CD1a presents diverse self and foreign lipids, and how such CD1a-lipid complexes are recognised by the r ....An investigation into CD1a, a versatile antigen-presenting molecule. This project aims to investigate how T lymphocytes are activated by lipids presented by the skin-associated antigen-presenting molecule, CD1a. Using X-ray crystallography and cellular immunology, we will provide fundamental insight into this poorly understood immunological axis. We will determine the molecular basis for how CD1a presents diverse self and foreign lipids, and how such CD1a-lipid complexes are recognised by the responding T cells. This basic science discovery project will provide substantial new knowledge in the burgeoning field of lipid-mediated immunity, which should ultimately lead to new therapies targeting the CD1a lipid display molecule to either prevent immune mediated damage or promote protective immunity as required.Read moreRead less
Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an i ....Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an initial screen, distinct variants and combinations of these genes were identified. This project aims to interrogate how variation in these critical genes impacts on the function of cytotoxic lymphocytes, providing insights into the evolutionary drivers of immune recognition mechanisms.Read moreRead less

Decoding the evolution of killer T cell immunity across human lifetime. The immune system is a potent weapon for protection against pathogens. T cells have a central role as their receptors monitor the body for threats. The thymus (organ) educates receptors to discriminate between healthy and infected cells. Receptor diversity and T cell strength change throughout human life. This project aims to unravel how T cells gain and lose optimal receptors and strength. The aims are to understand 1) The ....Decoding the evolution of killer T cell immunity across human lifetime. The immune system is a potent weapon for protection against pathogens. T cells have a central role as their receptors monitor the body for threats. The thymus (organ) educates receptors to discriminate between healthy and infected cells. Receptor diversity and T cell strength change throughout human life. This project aims to unravel how T cells gain and lose optimal receptors and strength. The aims are to understand 1) The role of thymic education in diversifying receptors 2) Whether gradual loss of thymic education affects receptor diversity 3) The molecular mechanisms underlying T cell strength. The project is essential for understanding how optimal T cell immunity is formed, critical if we wish to harness this to improve healthy aging.Read moreRead less
An investigation into the basis of the T-cell mediated adaptive immune response. Understanding the adaptive immune response to human pathogens is critically important to develop strategies to combat infection. This project will provide a better understanding of how T cells combat viral infection, and will lead to fundamental advances in our understanding of viral immunity and the development of novel immunotherapeutic strategies.
Redefining the immune landscape of the human ocular surface. At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas. Int ....Redefining the immune landscape of the human ocular surface. At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas. Integrating state-of-the-art techniques, we will advance understanding of immune regulation at the human ocular surface by comprehensively defining immune cell biology and dynamics. We will define the effect of age on immune cells in these tissues, and relationships between the tear proteome and cell behaviours.Read moreRead less
