Knowledge of the domains and actions of these genes in the biosynthetic pathway may lead to the ability to engineer secondary metabolites with altered specificity, and drugs that alleviate symptoms of secondary fungal toxicoses associated with leukemia, organ transplants and HIV AIDS. Also this project will also elucidate the role of an EPT, sirodesmin, in blackleg of canola, a disease that costs the Australian canola industry up to $50 million in losses annually. Outcomes of this project may lead to novel blackleg disease control strategies. Read moreRead less
Improving and manipulating the immune adjuvant properties of recombinant fowlpox vectors. Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. 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.

Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. 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
Mimetics and small chemical compounds for hemopoietic stem cell mobilisation. This project will result in the design and synthesis of new chemical compounds that could be used clinically to help collect blood stem cells for bone marrow transplantation. For patients this will mean more effective and less painful ways to collect stem cells and better transplant outcomes. There is a large, ongoing international market for this type of drug and likelihood of significant financial benefit.
Role of the PU.1 transcription factor in regulating lymphoid development. Haemopoiesis is a tightly regulated process and provides an important model for our understanding and application of stem cell biology. Perturbation of early haemopoiesis results in a number of important disorders including leukaemia, anaemia and immunodeficiency. The application of stem cells to many disease conditions is currently being pursued, however, in order to develop therapeutic interventions knowledge of normal c ....Role of the PU.1 transcription factor in regulating lymphoid development. Haemopoiesis is a tightly regulated process and provides an important model for our understanding and application of stem cell biology. Perturbation of early haemopoiesis results in a number of important disorders including leukaemia, anaemia and immunodeficiency. The application of stem cells to many disease conditions is currently being pursued, however, in order to develop therapeutic interventions knowledge of normal cellular differentiation is crucial. The studies outlined here aim to contribute to the understanding of the these processes and hence help to provide the framework for future studies aimed at more directly altering cell fate decision for clinical applications.

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
