Summary
A ‘curative’ food allergy treatment is needed to prevent deaths and improve care. We recently showed that probiotic peanut oral immunotherapy (PPOIT) was highly effective for treating peanut allergy. 82% of PPOIT treated children gained tolerance compared to 4% of the placebo group. We will now test the combined probiotic-food OIT approach for treating prawn allergy. If successful, we will have identified the first treatment for prawn allergy and a platform treatment for other food allergies.

Summary
Primary hip replacement is a successful intervention for hip disease, but 10-15% of hip prostheses fail and require revision surgery within 10-15 years. At the time of revision, significant bone loss around the failed prosthesis is not uncommon. A bone reconstruction procedure, called impaction grafting, where donor bone is minced and placed in the areas of deficient bone before implanting the new prosthesis, has shown to give good results at more than ten years in some centres.

At the time of revision, significant bone loss around the failed prosthesis is not uncommon. A bone reconstruction procedure, called impaction grafting, where donor bone is minced and placed in the areas of deficient bone before implanting the new prosthesis, has shown to give good results at more than ten years in some centres. A high incidence of early complications of this procedure have included loss of fixation within the bone. Fracture of the bone around prostheses has also reported in some centres. These events require more surgery, putting the patient at higher risk greater complications and longer rehabilitations. Recent improvements in surgical technique and donor bone preparation have improved results. A current debate questions whether the dose of irradiation can be reduced from 25 kGy, while maintaining sterility of allografts. The risk of bacterial contamination in allografts is low, and irradiation reduces the mechanical strength of the graft, contributing to complications when irradiated bone is used. The benefits of decontaminating the bone may be outweighed by the higher risk for failure due to poor bone quality and resulting prosthesis instability. We will use ISO standards to test the validity of radiation dose for sterilising bone ex vivo. In the absence of controlled human studies, our aim is also to compare the results of impaction grafting with non-irradiated bone versus bone irradiated at current doses used by Australian bone banks, and lower doses indicated by ex vivo testing. We will use a large animal model of revision hip replacement, with precise measures of prosthesis stability. The results of this study will guide clinical decisions regarding the efficacy of current bone graft preparation procedures and the use of irradiated bone in human hip replacement surgery.Read moreRead less
A New Target For Allergic Inflammation: The Sphingolipid Pathway

Summary
Collectively, allergic diseases contribute immensely to the burden of health care in Australia. Notably, allergic reactions are symptomatic responses to a normally innocuous environmental antigen. Allergic diseases include asthma, hay fever, food allergy, anaphylaxis, insect sting and drug allergy. This project aims to understand the underlying mechanisms associated with allergic reactions such that it may aid in the identification of novel targets for the development of new treatments.

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.

Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response.

Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines. Engineering FPV to make both a relevant antigen and a cytokine is proprietary technology. With our commercial partner and using experimental mice, we will test the concept that FPV making a model antigen and IL-4 initiate and/or maintain beneficial Type 2 responses. A successful outcome will guide clinical FPV-based vaccine development for the treatment of important human and veterinary diseases.Read moreRead less

Investigation of the fundamental roles of class Ib MHC (major histocompatibility complex) molecules in immunity. The proposed research program, using laboratory-based and synchrotron-based radiation, will provide insight into the roles of a poorly understood class of immune molecules. This will improve our understanding of the regulation of immunity, and the knowledge gained will increase Australia's international research profile.

Work/family balance is a focus of significant attention at the community, national and international level. This project will generate new knowledge about the ways in which employment regulation directly and indirectly impacts on employee work/family balance outcomes within different regional and industry contexts. A growing body of research recognises the linkages between employment regulation and effects on child and parent well-being and health, labour force supply and economic outcomes. However, little is known about how geographical location shapes work/family balance. The research will thus contribute to improved understandings and to better social policy at the local, state and federal levels.Read moreRead less

They participate in generating the cellular responses to hormones, antigens, growth factors and other physiological stimuli. The aims of this project are to elucidate cellular mechanisms that regulate interaction between the molecular components of store-operated calcium channel, Orai and STIM. Using techniques of electrophysiology and molecular biology we expect to answer a fundamental question how STIM and Orai proteins interact to form functional store-operated calcium channels, and how the expression of STIM and Orai is regulated.Read moreRead less
