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.

The Impact Of Obesity On Immunological Tolerance Of The Fetus
Funder
National Health and Medical Research Council
Funding Amount
$378,366.00
Summary
Obesity increases the risk of miscarriage during pregnancy. The reasons for this are not known, although it is thought that abnormal levels of hormones and metabolic parameters are a contributing factor. We hypothesise that the immune system plays a role. In this project we will determine if obesity upsets the fine-tuning of the immune system that is crucial for successful pregnancy. Understanding the reason behind adverse pregnancy outcome will allow appropriate management of maternal obesity.
Understanding Leukocyte Function In Inflammatory Disease
Funder
National Health and Medical Research Council
Funding Amount
$707,370.00
Summary
In inflammatory diseases such as rheumatoid arthritis, asthma and lupus, white blood cells accumulate in organs and cause injury. The focus of this project is to understand how white blood cells leave the bloodstream and enter tissues. In particular, this project examines their contribution to inflammatory diseases of the kidney. By understanding this process in greater detail, we may be able to design more specific therapies to combat these conditions.
The Role Of Kdm1a In Epigenetic Regulation Of Virus-specific T Cell Differentiation.

Summary
Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual. Unfortunately, our understanding of how protective immunity is established and maintained after infection or vaccination is lacking. This proposal will determine whether specific enzymes involved in rewriting the genetic blueprint are key for establishing and maintaining this protective capacity. Understanding these mechanisms has implications for vaccination ....Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual. Unfortunately, our understanding of how protective immunity is established and maintained after infection or vaccination is lacking. This proposal will determine whether specific enzymes involved in rewriting the genetic blueprint are key for establishing and maintaining this protective capacity. Understanding these mechanisms has implications for vaccination and improved immunotherapy strategies for cancer.Read moreRead less
The immune system must be tightly regulated to make sure that it makes the right response to effectively fight off infection whilst avoiding inappropriate responses that cause damage such as in autoimmunity, inflammation or allergy. This project studies patients who have genetic defects that affect their immune systems and make them susceptible to infection and/or harmful immune responses. This will reveal some of the critical signals that maintain immune control.
Prof Carbone’s laboratory specialises in the study of immunity at the body surfaces. These surfaces include skin and mucosal tissues such as respiratory and gastrointestinal tract, all of which are the common points of entry for a variety of infectious agents. He has found that there exist cells at these peripheral sites that are separate from the immune components that one finds in the blood and, more importantly, that provide a profound level of protection during new infection. He now propose ....Prof Carbone’s laboratory specialises in the study of immunity at the body surfaces.

Mapping The Molecular Blueprint For Immune Cell Differentitation
Funder
National Health and Medical Research Council
Funding Amount
$753,300.00
Summary
Killer T cells are white blood cells that are key for helping control virus infections and in the recognition and elimination of cells that have become cancerous. This proposal aims to identify novel molecular mechanisms that control the ability of killer T cells to mediate their antiviral and anti-cancer functions. This will provide molecular targets for possible clinical interventions designed to either promote immunity (vaccination) or limit damage caused by T cell responses that target self
The cell types of the blood, such as red and white blood cells, are produced in the bone marrow from a rare stem cell. The stem cell uses a handful of important master-regulatory genes that act in a hierarchy to promote the blood cell differentiation process. This research aims to understand how these master-regulators function in isolation and together in producing the white blood cells that are required for our immune response to microbes, vaccination and to prevent cancer.
Deciphering How TCR Affinity Regulates CD4 T Cell Help In Immunity And Autoimmunity
Funder
National Health and Medical Research Council
Funding Amount
$850,885.00
Summary
Immune responses require the coordinated interaction and cross-talk between two types of white blood cells known as CD4 and CD8 T cells. A dysregulated interaction between these cells could be the cause of autoimmune and persistent infections by pathogens leading to chronic diseases. The aim of this proposal is to provide a deeper understanding of CD4/CD8 T cell interactions to improve immune outcomes in many chronic diseases in which interaction between these two immune cells is critical.
A Novel Role For MHC Class II In Carbohydrate Presentation
Funder
National Health and Medical Research Council
Funding Amount
$703,030.00
Summary
Cells of the immune system swallow up foreign molecules and break them down to smaller fragments. T cells then identify the degraded antigen fragments and coordinate the immune response. In this project we will investigate how the T cells identify carbohydrates.
Defining Immune Regulation And T Cell Responses During Chronic Infectious Disease.
Funder
National Health and Medical Research Council
Funding Amount
$714,062.00
Summary
Chronic infectious diseases such as HIV/AIDS, tuberculosis, malaria and leishmaniasis are responsible for significant morbidity and mortality. They are all characterised by severe immune dysfunction. We will study a parasitic infection to identify important immune cell populations and molecules that promote chronic infectious disease. This knowledge will enable the development of better treatments and vaccines for range of infectious diseases that affect people in many parts of the world.
