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.

Development Of Guanylate Cyclase Activators For The Treatment Of Pulmonary Arterial Hypertension
Funder

Funding Amount
$137,684.00
Summary
Pulmonary arterial hypertension (PAH) is a life threatening condition with few treatment options. It is marked by shortness of breath and reduced energy as a result of an unexplained constriction of the blood vessels in the lung. This results in reduced life expectancy. We are developing a new treatment that will relax the blood vessels in the lung to improve quality and length of life.
Modulating Immune Responses By Targeting Dendritic Cells Using Dendritic Cell Specific Markers.
Funder
National Health and Medical Research Council
Funding Amount
$197,750.00
Summary
The ability to modulate immune responses would have major health benefits. Dendritic cells (DC) are key regulators of the immune system. Different types of DC possess different cell surface molecules and have differing regulatory functions. We have identified four novel DC surface molecules that can be used to target different types of DC. We aim to use antibodies against these molecules to either enhance the effectiveness of vaccines or to suppress autoimmune diseases.
Development Of Inhibitors Of PKCzeta For Targeting Vascular Leak
Funder
National Health and Medical Research Council
Funding Amount
$335,113.00
Summary
Vascular leak (permeability) is a chief pathophysiological mechanism of many inflammatory diseases and cancer. Effective methods of reducing vascular permeability are likely to reduce or prevent morbidity. At present there are no potent broad spectrum inhibitors of vascular permeability. This application focuses on the development of such inhibitors.

Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein ( ....Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein (cytokine) called tumour necrosis factor (TNF). TNF is known to activate specialised immune cells within the skin (Langerhan's Cells ) and we hypothesise that the interaction beween CT and LC via TNF is the pathway to the potent immune response. In this project we propose to investigate the cells and molecules involved in the immune effects of CT in the skin with a view to the development of new skin based vaccine strategies.Read moreRead less
The majority of deaths from cancer are due to metastasis, which is the formation of secondary tumours at sites remote from the primary tumour. Metastasis involves conversion of some tumour cells to an invasive, migratory form in a process that is controlled by small genetic regulators known as microRNAs. In this project we will conduct experiments aimed to provide a proof of principle demonstration in mice that microRNAs can be used to block the formation of metastases.
