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.

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

This proposal represents an excellent opportunity for Australian science to participate in state-of-the-art research into the immune system and to be internationally competitive with the best researchers in the field. By combining advanced microscopy techniques with well developed biological models used by researchers at the University of Melbourne, this project will greatly improve our understanding of the dynamic interactions that occur between cells of the immune system during infectious diseases. The insight provided by this project will facilitate the design of better vaccines for protection against diseases, including influenza.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 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 identifyin ....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 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

Summary
Multi-photon imaging for infection, immunity, and self recognition. 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 ....Multi-photon imaging for infection, immunity, and self recognition. 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.
Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is ....Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is generated in the immune response, and how it becomes narrowed with age or prolonged infection. This information can be used to design vaccines for persistent infections such as HIV, and to improve immune control of infection in the elderly.Read moreRead less
Enhancing immunogenicity of DNA vaccines by targeted delivery to antigen presenting cells. Vaccines have proven to be one of the most effective means of preventing infection and also provide promise as a treatment for cancer. However, the range of effective technologies that make possible the delivery of vaccines that can protect against a broad range of infections is limited. DNA based vaccines are attractive because they are relatively easy to produce against a wide range of infections. Howeve ....Enhancing immunogenicity of DNA vaccines by targeted delivery to antigen presenting cells. Vaccines have proven to be one of the most effective means of preventing infection and also provide promise as a treatment for cancer. However, the range of effective technologies that make possible the delivery of vaccines that can protect against a broad range of infections is limited. DNA based vaccines are attractive because they are relatively easy to produce against a wide range of infections. However, DNA vaccines often provide poor protection against infections. This project will explore a unique technology developed in Australia and that will greatly improve the effectiveness of DNA vaccines against a broad range of diseases. Read moreRead less
BIOSYNTHESIS OF A FUNGAL TOXIN AND ITS ROLE IN PLANT DISEASE. This project will determine how an important class of toxic molecules, epipolythiodioxopiperazines (EPTs), are made by fungi. 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

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.
