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.

Purinergic P2X7 Receptor As A Target For Antidepressant Drug Discovery

Summary
Depression is the most common mental disease. Around one million Australian adults and 100,000 young people live with depression each year resulting in significant economic, social and personal costs. Despite multiple treatments of depression, there are still several serious unmet needs with most current antidepressants showing limited effectiveness. We have identified a novel protein in the brain that represents an innovative approach to providing a platform for antidepressant drug discovery.
Inhibition Of Endothelial Cell Adhesion Molecule Expression By High Density Lipoproteins

Summary
It is well known that high levels of cholesterol in blood cause coronary heart disease. However, it is also known that not all of the blood cholesterol is bad. If it is carried in particles called low density lipoproteins or LDLs it causes heart disease. But if it is carried in other particles known as high density lipoproteins or HDLs it does not. In fact, it is now well known that HDLs actually protect against the development of coronary heart disease.

However, it is also known that not all of the blood cholesterol is bad. If it is carried in particles called low density lipoproteins or LDLs it causes heart disease. But if it is carried in other particles known as high density lipoproteins or HDLs it does not. In fact, it is now well known that HDLs actually protect against the development of coronary heart disease. There are two main actions of HDLs that contribute to their ability to protect. Firstly, they are known to drain cholesterol out of coronary arteries. We have recently shown that they have a second action. The end result of this second action is a slowing down of the entry into coronary arteries of cells called monocytes that are necessary for the development of the atherosclerosis that causes the heart disease. This project is concerned with this ability of HDLs to slow down the development of atherosclerosis by the second action. We have found that this second action of HDLs is influenced by the type of fats they carry. We propose now to investigate the mechanism by which different fats influence this action of HDLs with a view to devising new strategies for the prevention of heart disease.Read moreRead less
Structural Biology Of Malaria Parasite Invasion And Antibodies-mediated Inhibition
Funder

Funding Amount
$1,562,250.00
Summary
Malaria results in significant mortality but an effective vaccine does not yet exist. The Rh5-CyRPA-Ripr complex is essential for malaria parasite to invade erythrocytes and is the leading vaccine candidate. We aim to visualise the atomic details of the Rh5-CyRPA-Ripr complex during parasite invasion of erythrocytes and how antibodies neutralise this key protein complex. This information will advance knowledge on malaria parasite invasion, which will help to design an effective malaria vaccine.
