Funding Amount

Summary
T lymphocytes play a pivotal role in the immune system by recognising virus-infected tissue and tumour cells through the use of specific cell surface receptors called T cell receptors (TCR). This project will study why partcular TCRs are used by the immune system, and will also examine the specificity of T cell recognition by determine the range of molecules an individual T cell can recognise. The work will aid in the development of new intelligent vaccines for cancer and infectious disease.
An X-ray Crystallographic Investigation Into The Structural Basis Of T-cell Allorecognition

Summary
X-ray crystallography is an essential tool for solving the three-dimensional (3-D) structure of proteins. Proteins control the biological processes within the cell and it is the exact shape of proteins that determines how they function. Each protein is made up like a string of beads, with the building units being amino acids. Depending on the sequence of the amino acids, the protein molecule bends and forms a distinct, complex shape. This three dimensional shape allows it to specifically interac ....X-ray crystallography is an essential tool for solving the three-dimensional (3-D) structure of proteins. Proteins control the biological processes within the cell and it is the exact shape of proteins that determines how they function. Each protein is made up like a string of beads, with the building units being amino acids. Depending on the sequence of the amino acids, the protein molecule bends and forms a distinct, complex shape. This three dimensional shape allows it to specifically interact with carbohydrates, other proteins, such as enzymes or receptors, or even with molecules like DNA, to have its effect. To determine how a protein acts, it is vital to know the precise three-dimensional shape of a protein at the atomic level. This work is focused on understanding the precise shape of proteins that control the immune system. The immune system is avital process whereby individuals can fight off disease. This work will further our understanding of the immune system.Read moreRead less
The Structure And Composition Of The T-cell Receptor-CD3 Complex

Funding Amount
$434,644.00
Summary
Our research will provide a fundamental advance in our understanding of how foreign viruses and pathogens trigger the immune system. Gaining a greater understanding of these central events will facilitate the design of novel therapies to treat immune associated disorders such as transplant rejection, autoimmune disease and some cancers.

Characterisation And Development Of Type-2 NKT Cells

National Health and Medical Research Council
Funding Amount
$853,885.00
Summary
Humans defend themselves from foreign pathogens by mounting a protective immune response. Type-2 NKT cells recognise foreign lipid molecules and play a key role in immunity. This project is designed to understand to how Type-2 NKT cells develop within the body, how they recognise lipid molecules and how they carry out their immune functions. This work will have important implications in understanding the role of NKT cells in human health and disease.
NKT cells are a type of lymphocyte with the ability to prevent a broad range of diseases including cancer, autoimmunity, infection and graft rejection. Sometimes, NKT cells also cause diseases, including allergy and atherosclerosis. This project will investigate how NKT cells become activated in these diseases by studying their surface receptors and what these receptors interact with.
Recognition Of Lipid Antigens By CD1d-restricted Type-2 NKT Cells

Funding Amount
$417,684.00
Summary
Protection against infection depends on T cells, which recognise and target foreign molecules called antigens via a specialized antigen receptor known as a T cell receptor (TCR). This project focuses on a specialised population of T cells called Natural Killer T (NKT) cells that recognise lipid antigens. The work outlined in this grant will increase our understanding of how different TCRs can recognise diverse lipid antigens thus providing insight into the role of NKT cells in the immune system.
T-cells: The Key To Unlocking Immunity Against Aggressive Lymphoma

Funding Amount
$322,951.00
Summary
By investigating several aspects of patients’ immune defenses against the cancer cells in Diffuse large B-cell lymphoma, this project will provide critical insights on ways to harness the patient’s own immune system to effectively mount anti-tumour responses. These results will pave the way for future therapeutic strategies to successfully treat and prevent lymphoma.
