While current influenza vaccines blunt winter epidemics, they must be updated frequently to keep up with virus mutation and they do not protect against pandemics caused by new flu viruses (such as bird flu). This program will define how flu virus interacts with the immune system to generate immunity mediated particularly by “killer” T cells. We will use this knowledge to develop and evaluate vaccines that induce long-lasting T-cell immunity that can protect against both seasonal and pandemic flu ....While current influenza vaccines blunt winter epidemics, they must be updated frequently to keep up with virus mutation and they do not protect against pandemics caused by new flu viruses (such as bird flu).

Summary
The study will investigate why humans cannot eradicate particular viruses (HIV-AIDS, cytomegalovirus and herpes simplex virus), the long term effects of these viruses and ways to improve control. Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully ....The study will investigate why humans cannot eradicate particular viruses (HIV-AIDS, cytomegalovirus and herpes simplex virus), the long term effects of these viruses and ways to improve control. Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully persist within reservoirs in the human body. The research program brings together a group of 6 leading scientists and clinicians located at 3 sites in 2 Australian cities. The team is comprised of experts in the study of HIV-AIDS, cytomegalovirus and herpes simplex virus who will combine their knowledge and expertise to speed up the process of research on these viruses that are of major health importance. Studies will also utilise a number of cutting edge technologies that now make it possible to much more rapidly and precisely determine how viruses cause disease. Advances in our understanding of how viruses persist may form the basis for treatments aimed at controlling persistent infections and the serious diseases caused by these viruses.Read moreRead less

The Chief Investigators, Prof David Cooper, Prof Peter Doherty (Nobel Prize winner), A-Prof Stephen Kent and Prof Ian Ramshaw, have achieved major scientific developments including: innovative collaborative clinical trials, cutting edge research in T cell immunology, the establishment of the only PC3-level nonhuman primate facility in the Southern hemisphere, T cell immunogenicity of the DNA-viral vector prime-boost vaccine regimens and ground-breaking research on cytokine co-expressing viral vector vaccines. The Principle Investigators also have a record of substantial achievement in relation to HIV and T cell biology as well as novel vaccination technologies. There is a strong history of successful collaboration among this group leading to the award of major NIH funding.Read moreRead less

Summary
The early events in immunity require various molecular interactions. We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will ....The early events in immunity require various molecular interactions. We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will address the structural and biochemical basis for operation of an immune molecule called tapasin and unravel the basis for how some viruses escape the function of this molecule, thus allowing their immune evasion. We will also explore the use of modified small proteins called peptides in a humanized model of gluten hypersensitivity resembling that of Celiac disease. The molecular basis of the natural human immune system's capacity to recognise and reject grafts will be examined. This complements work aimed at improving the prediction of clinical graft rejection in transplantation. Dendritic cells play a central role in immunity, responsible for capturing material, whether from micro-organisms or self tissues, and presenting it to cells of the immune system. Our program will study the development and immunological function of the different dendritic cell subtypes. We will determine the relative contribution of each to the maintenance of immune tolerance and to the induction of immunity to several pathogens, including herpes simplex virus and malaria. Novel dendritic cell surface molecules that we have discovered will be tested for their ability to enhance the effectiveness of vaccines. Overall, this program utilises a broad array of immunological techniques designed to dissect the development and function of various immune system cell types and determine the structure-function relationships between important cell surface molecules involved in immunity.Read moreRead less

We are investigating whether the introduction of Wolbachia micro-organisms into mosquitoes can be used to selectively eliminate old mosquitoes and reduce transmission of human pathogens. We will also determine whether Wolbachia have any non-lethal affects on mosquito behaviours such as dispersal and biting activity which determine the level of contact between mosquitoes and humans.Read moreRead less

The second virus is human cytomegalovirus which can cause birth defects and problems in transplant patients. In this program we are investigating how the body�s immune system controls these viruses to exploit this information to develop new treatments.Read moreRead less
