Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and ....Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and death are controlled. It combines methods we developed to track MAIT cells in vivo with expertise in cell death analysis. This project is expected to elucidate the complex mechanisms controlling MAIT cell survival/death and increase our fundamental understanding of cell death mechanisms of activated T cells.Read moreRead less
New technology for the delivery of peptide-based T-cell vaccines for tumour immunotherapy. This project is dedicated to finding simple methods for vaccinating humans and animals against a wide variety of cancers. Should this be achieved millions of Australians will be protected from the devastating consequences of cancer. Consequently there will be great benefits socially, medically and economically.

Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.
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

Multi-photon imaging for infection, immunity, and self recognition. This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body. The intravital imaging system will provide novel insights into how the immune system works, which will ....Multi-photon imaging for infection, immunity, and self recognition. This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body. The intravital imaging system will provide novel insights into how the immune system works, which will benefit the design of vaccines, the treatment of cancer, and our understanding of allergy. This state-of-the-art facility will also provide vital training in an emerging technology that will have application in many areas of biology.

The Zeiss LSM 7MP 2-photon imaging system will provide enhanced capacity to directly visualise cellular and molecular events in real time, with greater sensitivity and in a broader range of tissues and organs. This will provide the opportunity for novel insights into numerous immunological and host-microbe interactions.Read moreRead less
Atypical T cell receptor recognition of monomorphic CD1 antigen-presenting molecule. T lymphocytes are white blood cells that respond to foreign molecules (antigens). Until recently, most known antigens were proteins. This project will study how T lymphocytes recognise a different class of antigen (glycolipids) that are likely to play an equally important role in the immune system.
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
Gamma delta T cells specific for glycolipid antigens. Gamma delta T cells are an enigmatic component of the immune system that use a unique class of cell surface receptors (gamma delta T cell receptors). Despite having been discovered 30 years ago, very little is known about what these cells recognise and respond to, and therefore what is their function. A population of gamma delta T cells that respond via their T cell receptor to particular forms of lipid molecules presented by an antigen prese ....Gamma delta T cells specific for glycolipid antigens. Gamma delta T cells are an enigmatic component of the immune system that use a unique class of cell surface receptors (gamma delta T cell receptors). Despite having been discovered 30 years ago, very little is known about what these cells recognise and respond to, and therefore what is their function. A population of gamma delta T cells that respond via their T cell receptor to particular forms of lipid molecules presented by an antigen presenting molecule, CD1d has been identified. The aim of this project is to isolate these T cell receptors and investigate the interaction at the molecular level in order to understand the parameters that trigger activation of these cells. This will provide fundamental insight into a key component of the immune system.Read moreRead less
