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
Imaging of immune responses to pathogens in vivo. 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 betwee ....Imaging of immune responses to pathogens in vivo. 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
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.

Summary
Argonaute proteins and the mammalian antiviral response. Awarded the Nobel Prize for Medicine in 2006, RNA interference (RNAi) is a natural process that plants use to attack viruses. Humans possess all of the tools for RNAi, but whether it is used for antiviral defense is unknown. This project aims to uncover this immune process which will open new avenues to treat virus infections, from influenza to HIV.
