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.

Optimizing Implanted Cell Survival Using A Tissue Engineering Model
Funder
National Health and Medical Research Council
Funding Amount
$589,175.00
Summary
Cell therapy and tissue engineering involve the insertion of specific cells into damaged tissues or into a bioraector in a patient's body to generate new replacement tissues. This project seeks to improve two factors associated with inserting cells : 1. The innate survival characteristics of the cells being inserted, and 2. The blood vessel supply at the site of insertion. These techniques will greatly improve the survival of inserted cells.
The Role Of Apolipoprotein E In High Density Lipoprotein Metabolism

Summary
Coronary heart disease is a major cause of death and disability in Australia. A high level of blood cholesterol increases the risk of developing coronary heart disease. This increase in coronary risk is caused by the cholesterol that is carried in low density lipoproteins (LDL). However, not all cholesterol is bad. A proportion of the cholesterol in blood is carried high density lipoproteins (HDL), which are powerful protectors against heart disease. People with high blood levels of HDL have a s ....Coronary heart disease is a major cause of death and disability in Australia. A high level of blood cholesterol increases the risk of developing coronary heart disease. This increase in coronary risk is caused by the cholesterol that is carried in low density lipoproteins (LDL). However, not all cholesterol is bad. A proportion of the cholesterol in blood is carried high density lipoproteins (HDL), which are powerful protectors against heart disease. People with high blood levels of HDL have a significantly reduced risk of developing heart disease. HDL consist of several different types of particles that contain lipids (or fats) and proteins. Not all HDL protect equally against coronary heart disease. Our ability to determine which HDL are the most cardioprotective is limited because it is difficult to separate the different types of particles from each other. One thing we do know is that the cardioprotective properties and metabolism of HDL are influenced by the proteins they contain. A considerable amount is known about the effects of the two main HDL proteins on the metabolism and cardioprotective properties of HDL. However, HDL contain several other proteins which are also important in this regard. This project is concerned with one of those other proteins called apolipoprotein E. The evidence that apolipoprotein E protects against heart disease is indisputable. Despite this, almost nothing is known about its role in HDL metabolism. This is because it is difficult to isolate large amounts of apolipoprotein E-containing HDL from plasma. In order to overcome these problems I have developed a novel method for preparing HDL which contain apolipoprotein E. These preparations are comparable to the apoE-containing HDL in human plasma. They will be used in this project to study the influence of apolipoprotein E on HDL metabolism.Read moreRead less
Interactions Between Integrative Genomic Islands And Plasmids; Role In The Spread And Loss Of Antibiotic Resistance And Pathogenicity Determinants
Funder
National Health and Medical Research Council
Funding Amount
$776,465.00
Summary
Mobile elements that integrate into bacterial chromosomes at a specific site contribute pathogenicity and antibiotic resistance determinants to their bacterial host but only a few are able to move themselves into new hosts. Some plasmids and some elements can help certain others. In this project, genetic approaches will be used to investigate how plasmids and integrative elements help one another move into a new bacterium or compete with one another to stay in the same cell.
