The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

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
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
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
Body fluids: sweet protection against infection? Serious health problems caused by pathogenic microorganisms are in sharp increase due to aging population, escalating numbers of immunocompromised people and the increased resistance of microorganisms to currently available antibiotics. Our research will lead to development of new approaches to protect people and animals from pathogens before they invade the body. The commercial possibilities for new and natural antimicrobials are present from bot ....Body fluids: sweet protection against infection? Serious health problems caused by pathogenic microorganisms are in sharp increase due to aging population, escalating numbers of immunocompromised people and the increased resistance of microorganisms to currently available antibiotics. Our research will lead to development of new approaches to protect people and animals from pathogens before they invade the body. The commercial possibilities for new and natural antimicrobials are present from both the health and agricultural sectors in Australia and abroad. The technologies used and further developed will serve as a state-of-the-art training ground for the next generation of postgraduate students encompassing the integration of genomics, proteomics and glycomics technologies.Read moreRead less
Identifying the pathways employed by growth hormone to regulate the proliferation of adult neural stem cells. As stem cells underpin the maintenance and regeneration of the brain and are known to decline in number and competence with age; understanding exactly how these cells are regulated is of broad national benefit. Furthermore, given the regulatory role of growth hormone throughout the body, insights gained from this project should lead to the discovery of novel therapeutic targets both with ....Identifying the pathways employed by growth hormone to regulate the proliferation of adult neural stem cells. As stem cells underpin the maintenance and regeneration of the brain and are known to decline in number and competence with age; understanding exactly how these cells are regulated is of broad national benefit. Furthermore, given the regulatory role of growth hormone throughout the body, insights gained from this project should lead to the discovery of novel therapeutic targets both within and outside the nervous system, ultimately leading to preventative and restorative strategies for maintaining good health. Finally, this Proposal is of significant national benefit as it will undoubtedly advance our knowledge base in stem cell biology, helping to maintain Australia as a global leader in stem cell research.Read moreRead less

Multiphoton confocal microscope. Recent developments in light microscopy have revolutionised modern molecular and cellular biology. Dramatic improvements in microscope hardware and software and in the range of fluorescent markers used to tag selected cellular components now provide new and exciting opportunities to localise and determine the function of ions and molecules not only in preserved samples but also, most excitingly, in living cells. The proposed multiphoton confocal microscope will ....Multiphoton confocal microscope. Recent developments in light microscopy have revolutionised modern molecular and cellular biology. Dramatic improvements in microscope hardware and software and in the range of fluorescent markers used to tag selected cellular components now provide new and exciting opportunities to localise and determine the function of ions and molecules not only in preserved samples but also, most excitingly, in living cells. The proposed multiphoton confocal microscope will allow researchers in Canberra to obtain high quality images of static and moving components in living cells and tissues and will facilitate the discovery of new knowledge that contributes to our understanding and control of development and disease in both plants and animals.Read moreRead less
