Funding Amount

Summary
Patients with lymphoma cancers initially respond well to treatment, but later relapse with disease. The immune system can be effective at controlling cancer. A potential treatment option is to boost the natural immune response against cancer. This study investigates a vaccine that activates a certain immune cell, NKT cells, to fight lymphomas by delivering an NKT cell-activating molecule. Outcomes will allow assessment of combining an NKT-based vaccine with established treatments for lymphoma.
Host Metabolism And Responses Contributing To Flavivirus Replication And Pathogenesis

Funding Amount
$592,772.00
Summary
We aim to determine how viruses affect the cells they infect, In particular how they can alter the metabolism and balance of lipids in cells and how this impacts the bodies capability to respond immunologically. We believe that by understanding these basic principles we can target ares fr antiviral therapeutic potential.
An Investigation Into The Adaptive Immune Response In Celiac Disease

National Health and Medical Research Council
Funding Amount
$597,167.00
Summary
Celiac Disease (CD), an autoimmune-like disease that is triggered by the ingestion of dietary wheat gluten, or related proteins from rye and barely, affects ~1% of the population, causing tissue damage in the small intestine. The only available treatment is strict adherence to a lifelong gluten free diet. Our project aims to understand, at the molecular level, how components of the immune system and gluten interact to trigger the immune response that leads to CD symptoms.
In Vivo Imaging Of Virus-specific T Cell Responses In The Skin

Funding Amount
$332,258.00
Summary
Effective vaccination against many viral infections such as Herpes Simplex Virus (HSV) may be achieved by directing the cells of the immune system to specific sites in the body where they can lie in wait against the disease. To direct the immune system in this way, we must first understand how immune cells orchestrate themselves in tissues. This project will utilise advanced imaging techniques to study immune cells in real time to understand how they protect against viral infections in the skin.
Analysis Of Antigen Receptor Sharing By T And B Lymphocytes

Funding Amount
$540,356.00
Summary
To survive an infection the immune system must rapidly expand the number of immune cells that have pathogen-specific receptors that recognise, and therefore specifically combat, the infection. This normally occurs through proliferation of the immune cells. We have found that in addition to proliferation, the number of cells with these receptors can be increased by a process of receptor transfer between cells. This grant aims to further advance our understanding of this novel phenomenon.
Determining Regulators Of ILC3 In Mucosal Barrier Function And Immune Homeostasis

Funding Amount
$705,209.00
Summary
Innate lymphoid cells (ILCs) are specialized cells that defend the body against invading microorganisms at the body’s surfaces, mediate pathogen clearance and tissue repair but may also drive inflammatory conditions such as allergic asthma and inflammatory bowel disease. We will investigate the molecular switches that regulate this novel cell type and potentially uncover novel molecules or pathways for therapeutic targets.
Determining The Role Of DOCK8 In CD4+ T And B Cell Differentiation And Its Implications On Autosomal Recessive Hyper IgE Syndrome (AR-HIES)
Funder
National Health and Medical Research Council
Funding Amount
$512,600.00
Summary
Autosomal recessive hyper IgE (AR-HIES) syndrome due to mutations in DOCK8 is a rare primary immunodeficiency whereby patients present with susceptibility to severe and recurrent viral infections as well as an increased risk of developing cancer, severe food and environmental allergies, and atopic disease characterised by hyper IgE and extreme eosinophilia. This grant will investigate how abnormal DOCK8 function in CD4+ T cells and B cells contributes to disease pathogenesis in AR-HIES patients.
The Phenotype Of Protective Cytotoxic T Cell Responses During Viral Infections

Funding Amount
$841,114.00
Summary
T cell responses are important to establish protection against pathogens and some cancer via generation of memory cells that can be maintained long term and defeat promptly re-infections. This proposal aim at determining important factors that drive the success of immunological memory by employing single cell technologies and unique longitudinal samples from subjects infected with hepatitis C virus. The finding of this study will inform current vaccine research and immunotherapies.
Novel Serological Tools To Aid Malaria Elimination In The Asia-Pacific

Funding Amount
$1,362,749.00
Summary
In 2014 Asia-Pacific leaders pledged a malaria free Asia-Pacific by 2030. We will contribute to this goal by developing novel antibody detection tests that can identify people with current and recent past infections. We will then evaluate the utility of these tests both in mass screening and treatment programs and for the rapid delineation of areas where transmission persists from those where it has been eliminated. This will address two major roadblocks to malaria elimination in our region.
Asymmetric Cell Divison In T Cell Development: Consequences For Immunity And Cancer
Funder
National Health and Medical Research Council
Funding Amount
$642,608.00
Summary
Human health depends upon the development of an immune system that can effectively control infection without damaging normal tissue. In this project, we assess a new paradigm by which immune cell development might be controlled, in which an immune cell precursor divides in such a way that its two daughters inherit different molecular constitutents that subsequently regulate the adoption of different cell fate. The likely consequences of this phenomonon on immunity and cancer will be explored.
