Role of the GxxxG domain in the function of mammalian prion proteins. Prion proteins have been associated with a number of diseases of humans and animals (such as Creutzfeldt-Jakob Disease in humans and BSE, or 'mad-cow' disease in cattle) which have had major public health, social and economic consequences in countries where they have been detected. This project will identify mechanisms by which a highly conserved region of the prion protein plays a role in the conversion to the disease associa ....Role of the GxxxG domain in the function of mammalian prion proteins. Prion proteins have been associated with a number of diseases of humans and animals (such as Creutzfeldt-Jakob Disease in humans and BSE, or 'mad-cow' disease in cattle) which have had major public health, social and economic consequences in countries where they have been detected. This project will identify mechanisms by which a highly conserved region of the prion protein plays a role in the conversion to the disease associated form. This will provide avenues for identifying the normal function of the prion protein, and increase our knowledge of prion biology. This will benefit both in terms of healthy ageing and in protecting the agriculture sector from prion diseases in farmed animals.Read moreRead less

Natural product drug discovery in Australia requires access to high throughput functional assays to guide the separation and of novel bioactives with therapeutic potential. By establishing the advanced molecular discovery and characterisation facility in an academic environment across two institutions, research programs in early drug lead discovery and characterisation will be accelerated. It will provide unique capabilities not currently available in Australia, and help Australian researchers remain internationally competitive in breakthrough science and frontier technologies. The research enabled by this facility will lead to development of new drug candidates by the emerging Australian biotechnology industry.Read moreRead less
Identification and characterisation of caspase inhibitors. Organisms use a tightly controlled process of cell death (termed apoptosis) to remove dangerous and unwanted cells. Dysregulation of this process can contribute to diseases such as cancer and autoimmune disease. Caspases are protease effectors of apoptosis. Regulation of their activity is vital for effective control of cell survival and death. Using a functional screening system invented by the 1st CI, we aim to isolate and characterise ....Identification and characterisation of caspase inhibitors.

Dysregulation of this process can contribute to diseases such as cancer and autoimmune disease. Caspases are protease effectors of apoptosis. Regulation of their activity is vital for effective control of cell survival and death. Using a functional screening system invented by the 1st CI, we aim to isolate and characterise novel inhibitors of caspases. Such inhibitors may in time be used as targets for development of therapeutic or diagnostic reagents aimed at manipulating the apoptotic process to diagnose, prevent or treat disease.Read moreRead less

This proposal will address a major gap in our mass spectrometry capabilities and aid in our understanding of protein interactions and tissue distribution in areas such as neuroscience, microbiology, immunology, and botany, as well as enhance our understanding of fundamental gas phase chemistry of protein molecules. It brings together a highly successful multidisciplinary team of high-profile researchers with a track record of collaboration and delivering outcomes from shared facilities. In addition to these key scientific outcomes this project will also facilitate the training of several new personnel in a skill area for which there is a critical shortage (mass spectrometry) and promote true cross-disciplinary skills.Read moreRead less
Dissecting the Parameters for the Generation of Cytotoxic T Lymphocyte Immunity. This project aims to identify mechanisms by which antigen-presenting cells, such as dendritic cells, prime CD8+ T cells to generate effector and memory populations at the molecular level. The specific intention is to identify reagents capable of licensing dendritic cells, and examine the down-stream gene products/pathways generated by these signals using microarray analyses. Such knowledge will provide new insight i ....Dissecting the Parameters for the Generation of Cytotoxic T Lymphocyte Immunity. This project aims to identify mechanisms by which antigen-presenting cells, such as dendritic cells, prime CD8+ T cells to generate effector and memory populations at the molecular level. The specific intention is to identify reagents capable of licensing dendritic cells, and examine the down-stream gene products/pathways generated by these signals using microarray analyses. Such knowledge will provide new insight into CTL generation by providing greater understanding of how multicellular systems function both at the cellular and molecular level.Read moreRead less

Disease caused by the bacterium Clostridium difficile are a significant food production animal and public health problem in many countries. Specific animal and human public health resources have been allocated in many countries in efforts to mitigate the growing epidemics. The study proposed in this application presents a significant opportunity to learn about the virulence factors of animal strains of this bacterium about which very little is known. This project will lead to rationally designed preventative and treatment strategies that apply to both animals and humans, thereby impeding epidemics caused by C. difficile in Australia.Read moreRead less
Studies on peripheral T cell memory. Success in vaccination depends on the ability of the immune system to remember prior encounter with an infectious agent. This immune memory appears to work well for certain infections but not others, essentially meaning that for these diseases, effective vaccines remain unavailable.

This immune memory appears to work well for certain infections but not others, essentially meaning that for these diseases, effective vaccines remain unavailable. This application describes experiments based on a new leukocyte or white blood cell population that has been overlooked in studies of immune memory. The work involves identifying how they are formed and how they behave within the body. This work will therefore contribute to the development and production of new-generation vaccines to these so far uncontrollable infectious diseases.Read moreRead less

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.

Development of purified antibodies that kill virus infected cells. This proposal will develop panels of purified and monoclonal antibodies that kill virus infected cells. These antibodies may show efficacy in preventing HIV infection. This is new technology that could subsequently be harnessed to protect or limit the devastating effects of chronic viruses such as HIV.
