Molecular determinants of an allergic response. Some humans develop allergies after exposure to environmental allergens while others do not. At present, the reason for this individual variation is not known. By comparing the processes activated in allergic versus non-allergic individuals, this study will identify critical molecules involved in making individuals susceptible to allergies, which will be used to develop safer and more effective allergy vaccines.

Summary
CSL Limited, an Australian owned global biopharmaceutical company, is developing the ISCOMATRIX (IMX) adjuvant for vaccines to prevent and treat serious human disease of global concern (e.g. cancer, pandemic flu, HPV, HCV). This study will identify the mechanisms of action of IMX in generating strong cellular immunity, how to enhance it further by combining with other immuno-modulators so as to develop novel IMX vaccines for the treatment of established cancer and persistent viral infections.
Investigation of the resilience of immune memory to manipulation by pathogens. Vaccines have a major impact on the wellbeing of humans as well as productivity and welfare of veterinary species and pets. New vaccines have therefore a tremendous effect on both the economy and the community. Here we investigate in how far an adjuvanted vaccine can influence the type of immune response induced during subsequent infection when the pathogen has developed mechanisms to subvert the induced protective im ....Investigation of the resilience of immune memory to manipulation by pathogens. Vaccines have a major impact on the wellbeing of humans as well as productivity and welfare of veterinary species and pets. New vaccines have therefore a tremendous effect on both the economy and the community. Here we investigate in how far an adjuvanted vaccine can influence the type of immune response induced during subsequent infection when the pathogen has developed mechanisms to subvert the induced protective immune response. This question has profound implications for all vaccine and adjuvant development activities, as the resilience of immune memory is not yet considered an important parameter in the design of adjuvants yet it is fundamental to the successful of vaccines against many pathogens.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.

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 novel vaccine delivery systems for induction of mucosal immunity in a large animal model. The induction of mucosal immune responses is a highly desirable goal in vaccine research and development, as it prevents entry of the large number of mucosal pathogens. This proposal aims to develop new mucosal vaccine delivery systems by combining intra-nasal, intra-lung and transcutaneous vaccine delivery with ISCOM-based adjuvants. The nature of the immune response will be analysed in real ....Development of novel vaccine delivery systems for induction of mucosal immunity in a large animal model. The induction of mucosal immune responses is a highly desirable goal in vaccine research and development, as it prevents entry of the large number of mucosal pathogens. This proposal aims to develop new mucosal vaccine delivery systems by combining intra-nasal, intra-lung and transcutaneous vaccine delivery with ISCOM-based adjuvants. The nature of the immune response will be analysed in real time using a sheep cannulation model. Subsequently, the efficacy of mucosal vaccination strategies will be tested in a chlamydia infection model.Read moreRead less
Understanding the dynamics of T cell responses to chronic infection. The health, social, and economic impact of chronic infections on the Australian and global populations is enormous. A major obstacle to the development of vaccines against chronic infections is that we have a poor understanding of immune responses to persistent infections. We aim to use bioinformatics and mathematical modelling to understand immune responses to persistent viruses so that we can improve the long-term immune cont ....Understanding the dynamics of T cell responses to chronic infection. The health, social, and economic impact of chronic infections on the Australian and global populations is enormous. A major obstacle to the development of vaccines against chronic infections is that we have a poor understanding of immune responses to persistent infections. We aim to use bioinformatics and mathematical modelling to understand immune responses to persistent viruses so that we can improve the long-term immune control of chronic viral infections such as the human immunodeficiency virus (HIV). This project will strengthen Australian research in the area of interdisciplinary approaches to immunology, which is becoming crucial to interpreting the rapidly increasing volume of data obtained using advanced experimental techniques.Read moreRead less
T cell recognition and control of virus: the balance between T cell receptor diversity and degeneracy. T cells provide an important line of defence in the immune system's resistance against infectious diseases. However, changes to the T cell population during prolonged infection, and with age, can compromise the immune system's ability to fight effectively viral infections. The proposed research will greatly improve our understanding of the recognition and control of viral infections by T cells. ....T cell recognition and control of virus: the balance between T cell receptor diversity and degeneracy.

However, changes to the T cell population during prolonged infection, and with age, can compromise the immune system's ability to fight effectively viral infections. The proposed research will greatly improve our understanding of the recognition and control of viral infections by T cells. The insights gained from this research will enable us to exploit key features of T cell responses to improve the outcome of viral infections in elderly individuals and to develop better vaccines for protection against a range of infectious diseases that affect the Australian population, including HIV and Hepatitis C.Read moreRead less

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
