This project aims to better understand the mechanisms of immune induction of a novel lung vaccination strategy. The ability to deliver vaccines that induce potent lung and body wide immune responses in a safe and efficient manner has wide implications for both human and animal health. Ultimately, the vaccine will be delivered to the lung as stable dry powders in an attempt to negate the need for a transport cold chain and therefore facilitate the distribution of the vaccines to remote areas. The project will not only benefit the Australian biotechnology industry but also the community at large and in particular those in remote areas without access to modern medical facilities.Read moreRead less
How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still p ....How the immune system recognises vitamin B-based allergies. This project aims to evaluate the range of molecules that can stimulate vitamin B-reactive T cells in mammals and amphibians, and the degree of conservation or variation in these molecules among diverse microorganisms. T cells are immune cells that recognise foreign molecules, including peptides, lipids and vitamin B metabolites, bound to specialised antigen-presenting molecules. In mammals, Mucosal Associated Invariant T cells, still poorly understood, recognise Vitamin B-based molecules. Combining immunology with structural biology and chemistry, this project aims to understand how the immune system detects molecules produced by diverse microorganisms.Read moreRead less

Defining the mechanisms of tissue-resident memory T cell development. We have recently identified a subset of T cells that reside at points of pathogen entry where they can effectively control infection. The ability of these T cells to offer local immunity has caused a paradigm shift in our view of how T cells protect against infection, drastically changing the way we think about designing T cell vaccines. This project aims to characterise this novel T cell subset, defining the fundamental requi ....Defining the mechanisms of tissue-resident memory T cell development. We have recently identified a subset of T cells that reside at points of pathogen entry where they can effectively control infection. The ability of these T cells to offer local immunity has caused a paradigm shift in our view of how T cells protect against infection, drastically changing the way we think about designing T cell vaccines. This project aims to characterise this novel T cell subset, defining the fundamental requirements for their formation and maintenance. This will lead to a greater understanding of their biology, which will be of significance for the development of novel vaccination strategies.Read moreRead less
A cellular hub for the organisation of T cell priming. This project aims to delineate the cellular interactions involved in the initiation of immune responses by utilising advanced in vivo imaging. Adaptive immunity in vertebrates functions via the acquisition of signals by immune cells via complex interactions with other immune cells, yet these exchanges are difficult to observe and define. This project expects to provide insights into the mechanisms that underpin effective cell-mediated immune ....A cellular hub for the organisation of T cell priming. This project aims to delineate the cellular interactions involved in the initiation of immune responses by utilising advanced in vivo imaging. Adaptive immunity in vertebrates functions via the acquisition of signals by immune cells via complex interactions with other immune cells, yet these exchanges are difficult to observe and define. This project expects to provide insights into the mechanisms that underpin effective cell-mediated immune responses. The expected outcomes are to generate fundamental new knowledge about immune responses and enhance capacity to study the immune system. This could benefit future development of new vaccines and therapies to improve health.Read moreRead less
Sphingosine-1-phosphate receptor 5: a novel regulator of T cell immunity. T cells provide critical immune protection against infection and cancer. However, the pathways that regulate these immune cells are not fully understood. T cells express a molecule called S1P5 that has an unknown function in these cells. In this proposal, we reveal new evidence that this molecule is an unappreciated and crucial regulator of T cell behaviour. Using state-of-the-art techniques and novel genetic tools, this p ....Sphingosine-1-phosphate receptor 5: a novel regulator of T cell immunity. T cells provide critical immune protection against infection and cancer. However, the pathways that regulate these immune cells are not fully understood. T cells express a molecule called S1P5 that has an unknown function in these cells. In this proposal, we reveal new evidence that this molecule is an unappreciated and crucial regulator of T cell behaviour. Using state-of-the-art techniques and novel genetic tools, this project aims to discover the involvement of S1P5 in the immune response, and determine how S1P5 can be controlled to enhance protective T cell immunity. The expected outcomes are to generate fundamental new knowledge that will have significance for regulation of the immune response. Read moreRead less
Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is ....Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is generated in the immune response, and how it becomes narrowed with age or prolonged infection. This information can be used to design vaccines for persistent infections such as HIV, and to improve immune control of infection in the elderly.Read moreRead less
Defining the immune properties of killer T cells resident in organs. Infections induce immune cells that are thought to recirculate through the blood. Recently, we discovered a population of immune cells that live in tissues like the skin and other tissues, providing critical protection against infections. This project aims to better describe this new immune population and determine ways to harness its potential.

Summary
An investigation into evolution and diversity within an innate immune recognition system. The innate immune system, which is critical for the host to combat infection, comprises a host of components that specifically recognise microbial products. This project is aimed at understanding the evolution and specificity underpinning a receptor family that is centrally involved in innate immunity.
