While protein recognition by the immune system is well understood, our knowledge of the fundamental features of lipid detection is poor.

While protein recognition by the immune system is well understood, our knowledge of the fundamental features of lipid detection is poor. This project will investigate the detection of lipid molecules that are presented to the immune system in association with a molecule known as CD1c. The aims are to understand: 1. The cells that respond to these lipids; 2. The cellular receptors that bind to these lipids; 3. The types of lipids involved in this process. This work is essential for us to understand lipid-based immunology which is critical if we ultimately wish to harness this to improve human health.Read moreRead less
Understanding T cell immunity induced by infection. We aim to understand how killer T cells are “programmed” upon activation and acquire their characteristic functions and how these are maintained into immunological memory. This proposal will provide insights important for the design and improvement of vaccine strategies to fight pathogens such as influenza, HIV and even tumors.
microRNAs and the control of T lymphocyte differentiation, function and malignant transformation. The molecular mechanism of the immune system is not completely understood. This project will investigate how transcription factors and microRNAs, two major types of regulatory molecules work together to control immune responses. The results from this research will assist in the design of better vaccination strategies and treat certain lymphomas.

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

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.
Mechanism of action of an anti-inflammatory compound which targets alternatively activated macrophages. The project will study the mechanism by which a novel anti-inflammatory compound, developed by our commercial partner, suppresses the activity of a population of cells known as alternatively activated macrophages. These cells play a key role in driving allergic inflammation, including the inflammation associated with asthma.
Antigen selection mechanisms control T cell immunity against bacteria. CD4+ T (T helper) cells are required to control many important bacterial infections. This Project aims to identify the key targets of CD4+ T cells responding to a model bacterial infection, and to correlate potential antigen effectiveness with native expression, antigen presentation, and the function of antigen-specific CD4+ T cells over time. Our validated experimental 'pipeline' has unprecedented potential to define potent ....Antigen selection mechanisms control T cell immunity against bacteria. CD4+ T (T helper) cells are required to control many important bacterial infections. This Project aims to identify the key targets of CD4+ T cells responding to a model bacterial infection, and to correlate potential antigen effectiveness with native expression, antigen presentation, and the function of antigen-specific CD4+ T cells over time. Our validated experimental 'pipeline' has unprecedented potential to define potent CD4+ T cell antigens within the thousands of proteins expressed by a bacterial pathogen. Our unbiased analysis may help establish the rules that define effective antigenicity. Our work will improve the understanding of bacterial immunity, and inform future design of T-cell based vaccines in the agricultural sector.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

The populations of endothelial and mesenchymal cells that construct the lymphoid tissues are being revealed as key players in the priming and orchestration of immune responses. Yet, fundamental knowledge of the molecular makeup and the functions of these stromal cells, particularly their roles in immune responses, is sorely lacking. This project will utilise a multidisciplinary approach including advanced imaging and bioinformatics to dissect the functions of the lymphoid stromal cells and their roles in the swelling of lymphoid tissues during immune responses. This will provide vital information about the biology of these understudied cells and reveal the ways in which they support the generation of immunity.Read moreRead less
