Summary
Cytokines or chemical messengers released by cells are essential for controlling immune responses but, in excess, they cause Crohn's disease and arthritis. Our research aims to block cytokine release as a novel way to ameliorate disease. We have identified specific cellular proteins, called golgins, that can be targeted to reduce cytokines. Here, characterization of golgin mediated cytokine transport in cells and in a mouse disease model is necessary to translate these findings for human benefit
Dissecting The Great Ophthalmic Masquerade: The Global Giant Cell Arteritis Genomics Consortium.

Summary
Giant cell arteritis (GCA) is the most common form of vasculitis in people over 50 years of age. If untreated it can cause catastrophic complications including blindness, though this can be prevented if treated early. Although there is clear evidence for a role of genetic factors in GCA, these have been little studied. We have established an Australian-led International consortium, with clinical, basic science and statistical expertise to thoroughly investigate this devastating disease.
Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
History in their bones: A diachronic, bioarchaeological study of diet, mobility and social organisation from Cambodian skeletal assemblages. Australia will further enhance its role as an innovator in the archaeology of SE Asia through this cross-disciplinary, international collaboration on the mobility, health, age and diet in ancient Cambodia. Local collaborations will be expanded and academic and cultural relations with Cambodia will be reinforced and strengthened. This research will expand ....History in their bones: A diachronic, bioarchaeological study of diet, mobility and social organisation from Cambodian skeletal assemblages. Australia will further enhance its role as an innovator in the archaeology of SE Asia through this cross-disciplinary, international collaboration on the mobility, health, age and diet in ancient Cambodia. Local collaborations will be expanded and academic and cultural relations with Cambodia will be reinforced and strengthened. This research will expand understanding of Cambodian history and underscore its pivotal role in mainland SE Asian archaeology. Australia's advancement of knowledge about Cambodia's rich cultural antiquity will be recognized worldwide by a global community acutely mindful of the losses to culture and heritage endured by Cambodia in the recent past.Read moreRead less
A new approach to reversing and preventing immune-mediated diseases. Chronic inflammatory diseases affect up to 20 per cent of Australians. These diseases reduce wellbeing and life potential and shorten lifespan. This project addresses the urgent need for effective therapies and focuses on developing strategies for disease cure and prevention.

National benefit will be accrued through the major scholarly contribution the project makes to a key debate in world archaeology, namely the extent to which environmental change affected ancient complex societies, especially climate change. As such it fosters an awareness of world cultures and the interrelation between political stability and environmental change. The project also will encourage international collaboration between Australian, Turkish and Japanese scholars and will provide training for several research scholars in an area of archaeology in which Australia has a recognised major deficit, namely archaeobotany.Read moreRead less
Macrophages are white blood cells that provide front line defence against infection by initiating inflammatory responses by ingesting or phagocytosing microbes and by releasing soluble messengers (cytokines) to recruit other immune cells. These defensive functions require extensive trafficking of proteins within the macrophages. Protein trafficking is orchestrated in part by a family of membrane fusion proteins called SNAREs. By defining the relevant SNAREs, we have recently discovered a much ac ....Macrophages are white blood cells that provide front line defence against infection by initiating inflammatory responses by ingesting or phagocytosing microbes and by releasing soluble messengers (cytokines) to recruit other immune cells. These defensive functions require extensive trafficking of proteins within the macrophages. Protein trafficking is orchestrated in part by a family of membrane fusion proteins called SNAREs. By defining the relevant SNAREs, we have recently discovered a much acclaimed and novel pathway that allows efficient, combined cytokine secretion and phagocytosis in macrophages. Our studies proposed here will now expand on this discovery by comparing the phagocytic process, in terms of SNARE-mediated membrane and cytokine trafficking, for a wide range of microbes, highlighting differences that could provide new avenues for drug development. Moreover, since our strategy of using SNAREs to investigate and map trafficking pathways has proven so successful, we will now launch a major large-scale initiative to study ALL SNARE-mediated trafficking pathways in macrophages using a discovery pipeline of assays, including live cell imaging, we have developed. This will provide valuable information on many SNAREs including those associated with disease, and will elucidate trafficking pathways governing all macrophage actions in immunity, including cytokine secretion and antigen presentation. All of these pathways are highly relevant to current drug targets being used clinically or studied in inflammatory disease and for the development of vaccines.Read moreRead less
Sterile inflammation as a determinant of adaptive immunity. When we injure ourselves, the site of injury becomes inflamed, which may help healing or cause trouble. This project aims to understand how the normal response to injury is controlled and why the process may sometimes go wrong.
