A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune respo ....A novel link between metabolism and host defence. This project aims to delineate how a protein modification that consists of the addition of a small sugar to cellular proteins, known as O-GlcNAcylation, provides a link between metabolism and complex cell functions. The model for these studies is a cell type of the immune system known as dendritic cells. Upon encountering pathogens these cells undergo metabolic changes that increase the rate of O-GlcNAcylation of proteins involved in immune responses, altering their function. This project will study how O-GlcNAcylation works and is regulated. The project expects to develop new technology and provide high-level training, increasing the competitiveness of the strategic biotechnology sector in AustraliaRead moreRead less
A study into post-translational modifications on adaptive immunity. Using proteomics, structural biology and cellular immunology, this project aims to provide a greater understanding of the impact of PTMs on the immune system. The immune system combats pathogens by mounting T-cell responses against foreign antigens present in infected cells. However, T-cells activated by self-antigens that are inadvertently presented by healthy cells can cause aberrant T-cell reactivity and disease.

Using proteomics, structural biology and cellular immunology, this project aims to provide a greater understanding of the impact of PTMs on the immune system. The immune system combats pathogens by mounting T-cell responses against foreign antigens present in infected cells. However, T-cells activated by self-antigens that are inadvertently presented by healthy cells can cause aberrant T-cell reactivity and disease. Post-translational modifications (PTMs) are common in the host's proteins, but surprisingly little is known about their effect on T-cell immunity.Read moreRead less
Identifying The Mechanism And Spectrum Of Activity Of The Antiviral Protein IFITM3

Summary
In response to an infection cells within the body are capable of expressing a range of molecules that help them resist infection, one such molecule is interferon induced transmembrane protein 3 (IFITM3). This recently identified but poorly studied potent antiviral protein dramatically influences the course of influenza infection in both mice and humans. We will explore the mechanisms of antiviral activity of IFITM3 and determine factors important in initiating and retaining expression.

Summary
The investigation of an unconventional Human Leukocyte Antigen molecule. This project aims to characterise a unique and understudied surface molecule (HLA-E). The immune system is activated and regulated by a complex set of molecules including HLA molecules present on the cell surface that inform the immune system of infection. Therefore, this project expects to generate new knowledge in the areas of cellular biology and immunology by utilising a cutting-edge and multi-disciplinary approach.

Therefore, this project expects to generate new knowledge in the areas of cellular biology and immunology by utilising a cutting-edge and multi-disciplinary approach. Expected outcomes of this project include the generation of new knowledge of this unconventional molecule and its interaction with immune cells. This should provide significant impacts by defining the non-conventional role of HLA-E within the immune system, which may advise future research into vaccines or therapeutics. Read moreRead less

Summary
José Villadangos studies the cells and molecules involved in Antigen Presentation. This phenomenon consists of the detection, capture and display of microbe fragments on the surface of Antigen Presenting Cells (APC) for recognition by T cells. This initiates an immune response that culminates in the deployment of cells and molecules armed to fight the infection. His research may lead to development of more effective vaccines and prevention of autoimmunity, allergy and transplant rejection.
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.

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
