Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase ge ....Mammalian chitinases and gene therapy: new weapons to combat fungal and insect attack in mammals. Plants combat fungal and insect attack by producing chitin degrading enzymes. Related, chitinolytic enzymes have been identified in mammals, but their functions are unclear. We found that chitinases from human macrophages inhibited fungal growth. We hypothesise that, like plants, mammalian chitinases are produced to fight chitin containing pathogens. We will transform cells with a chitotriosidase gene and encapsulate them, creating bioreactors secreting chitinases. Therapeutic effects will be tested by grafting bioreactors to mice inoculated with Aspergillus. The research is a new approach to fighting chitin containing pathogens, with potential applications from parasite infestations in livestock to fungal infections in humans.Read moreRead less
Defining targets and generating tools/therapeutic agents for prevention, diagnosis and therapy of atherothrombosis. Atherosclerosis and its complications such as myocardial infarction and stroke are a major cause of death and disability in Australia and worldwide. The proposed research program investigates new therapeutic targets and concepts (e.g. targeting of stem cells) to treat atherosclerosis and aims to develop new therapeutic agents using modern biotechnological methods. The project furth ....Defining targets and generating tools/therapeutic agents for prevention, diagnosis and therapy of atherothrombosis. Atherosclerosis and its complications such as myocardial infarction and stroke are a major cause of death and disability in Australia and worldwide. The proposed research program investigates new therapeutic targets and concepts (e.g. targeting of stem cells) to treat atherosclerosis and aims to develop new therapeutic agents using modern biotechnological methods. The project further aims to develop nanoparticle-based diagnostic tools to identify and preventatively treat atherosclerotic plaques that are prone to cause myocardial infarction. The expected outcome will provide direct benefit to patients and create new economic opportunities in Australian bio-/nanotechnology.Read moreRead less
DNA methylation-based diagnosis of cancer and identification of novel therapeutic targets. In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer. This project will identify defects in DNA methylation associated with cancer. Identifying these defects will enable us to design non-invasive, early diagnostic tests for cancer on b ....DNA methylation-based diagnosis of cancer and identification of novel therapeutic targets. In our aging society, cancer represents a severe economic and quality-of-life threat. DNA methylation switches genes off, and recently, it was shown that defects in DNA methylation contribute to human diseases including cancer. This project will identify defects in DNA methylation associated with cancer. Identifying these defects will enable us to design non-invasive, early diagnostic tests for cancer on blood or bodily excretions, and to pursue novel therapeutic approaches for treating cancer. The expected outcomes would generate exports to markets in the USA and Europe and replace imports of drugs and technology to treat cancer.Read moreRead less
Development of a prime-boost anti-cancer vaccine. New vaccination strategies are urgently needed for a variety of diseases, including cancer. The problem with cancer vaccines is that it is difficult to trigger a response to a self protein. We propose that a prime-boost vaccination, using yellow fever virus and modified vaccinia virus ankara, could create very strong responses against tumor antigens. This approach can be patented and can revive that field of tumor vaccination, which is currently ....Development of a prime-boost anti-cancer vaccine. New vaccination strategies are urgently needed for a variety of diseases, including cancer. The problem with cancer vaccines is that it is difficult to trigger a response to a self protein. We propose that a prime-boost vaccination, using yellow fever virus and modified vaccinia virus ankara, could create very strong responses against tumor antigens. This approach can be patented and can revive that field of tumor vaccination, which is currently restrained by the difficulty of breaking immunological tolerance. We envisage the construction of a anti-cancer vaccine vector with obvious market potential. An exciting prospect is that this approach could be used as a prophylactic vaccine and possibly also as a therapeutic vaccine.Read moreRead less
Drug particle characterisation. The understanding of drug particle characterizations is one of the key issues in the development of novel nasal sprayers for targeted drug delivery. A comprehensive study is proposed for characterising drug formation in sprayers and particle deposition in nasal cavity using the latest experimental and numerical techniques.

Dissecting the physiology of multipotent mesenchymal stromal cells to develop vaccine candidates for respiratory disease. The project aims to gain an understanding of how a type of adult stem cell inhibits immune responses that cause asthma. The project will produce new stem cell products and facilitate the design of a vaccine for asthma and other respiratory diseases, which would greatly reduce the burden of such conditions.
Intracellular trafficking and function of a recycling receptor which prolongs the serum half-life of novel therapeutic proteins. The life span of recombinant engineered proteins for therapeutic use is a critical factor in their effectiveness, ease of clinical application and cost. This project will exploit interactions with a natural receptor, which prolongs the lifespan of serum proteins, to enhance survival of therapeutic engineered proteins.
