Summary
Our research will provide a fundamental advance in our understanding of how foreign viruses and pathogens trigger the immune system. Gaining a greater understanding of these central events will facilitate the design of novel therapies to treat immune associated disorders such as transplant rejection, autoimmune disease and some cancers.

Summary
Cytokines are messenger proteins used by most cells of the body. They function as master regulators of many biological processes and as such play an important role in a wide spectrum of diseases. Anti-inflammatory cytokines attenuate the potentially destructive force of other cytokines and the immune system as a whole, and are therefore coveted as drug targets. We discovered the formidable anti-inflammatory properties of IL-37 and will now explore how these activites can be utilised in clinical ....Cytokines are messenger proteins used by most cells of the body.

The initial step of T cell activation of how the external ligand binding is translated to an increase of receptor phosphorylation at the cytoplasmic side is remain poorly understood. It is believed that the loss of immune recognition in cancer and over reactivity in auto-immune diseases are caused by abnormality of this transmembrane signalling transduction. Clarification of this molecular machinery can provide a molecular basis of those diseases and guidelines of more effective therapies.

Summary
This proposal is focussed on understanding the precise shape of proteins that control the immune response to Epstein Barr Virus. EBV is an ubiquitous human pathogen that has been linked to a number of cancers. This research proposal will further our understanding of the immune response to EBV, which will lay the foundations for developing therapeutics against this disease.

Summary
In order to recognize a wide variety of pathogens, humans produce many different T cell receptors (TCRs) by the process of gene-rearrangement. However, gene-rearrangement may not always lead to a functioning TCR. We are studying the pre-TCR protein that is responsible for monitoring the success of gene-rearrangement and is thus essential for the formation of a robust immune system. Understanding pre-TCR function will lead to new treatments for immune related diseases.

The project aims to establish a high throughput protein nanocrystallisation and imaging facility for protein crystallography. Protein crystallography is an important field of biological research, however there are many proteins, such as integral membrane proteins and transient molecular complexes that are more challenging to crystallise. The facility aims to use state-of-the-art imaging and crystallisation techniques, including second order nonlinear imaging of chiral crystals (SONICC) imaging and lipid cubic phase approaches, to enable structural studies to be undertaken on challenging proteins. This information is often used for the rational development of therapeutics. The facility would support cutting-edge biological research In Australia.Read moreRead less
A novel axis of cooperation between innate and adaptive immunity. The project aims to understand how two molecular components of the immune system, Complement and MHC, cooperate to protect the host. Further, these two molecules mediate trogocytosis, a little-studied form of intercellular communication, between two major immune cell types: dendritic cells and B cells. The project will be multidisciplinary, applying high-end microscopy, biochemistry, cell biology and immunology techniques. Person ....A novel axis of cooperation between innate and adaptive immunity.

The project will expand knowledge on basic immunology and cell-cell cooperation. It will generate intellectual property for the biotechnology sector to develop new commercial products that might improve the health of humans and also animals of economic importance.Read moreRead less
Analysis Of Antigen Receptor Sharing By T And B Lymphocytes

Summary
To survive an infection the immune system must rapidly expand the number of immune cells that have pathogen-specific receptors that recognise, and therefore specifically combat, the infection. This normally occurs through proliferation of the immune cells. We have found that in addition to proliferation, the number of cells with these receptors can be increased by a process of receptor transfer between cells. This grant aims to further advance our understanding of this novel phenomenon.

Elucidating the genesis of MAIT cell-mediated immunity. T cells develop in the thymus and proceed to survey our body probing molecules that signal if anything is abnormal. A specialised subset of T cells, mucosal associated invariant T (MAIT) cells are crucial in detecting microbial molecules and infection, yet their numbers vary widely between individuals. A key problem is that the factors controlling their development and function are poorly understood.

T cells develop in the thymus and proceed to survey our body probing molecules that signal if anything is abnormal. A specialised subset of T cells, mucosal associated invariant T (MAIT) cells are crucial in detecting microbial molecules and infection, yet their numbers vary widely between individuals. A key problem is that the factors controlling their development and function are poorly understood. This proposal aims to decode this critical issue in MAIT cell biology, using innovative tools to investigate the molecular basis underpinning their development in the thymus. This work will provide vital, fundamental discoveries into how MAIT cells are produced and regulated, as we ultimately wish to harness MAIT cells to improve human health. Read moreRead less
