Summary
It is becoming increasingly clear that cancerous tissues are not hidden from the body's immune system and yet, despite the generation of tumour-specific T cells and antibodies, the immune system does not often destroy solid tumour. Tumours express a large number of potential antigens (molecules in or on cancer cells that can be recognised by the immune system), but T cell responses to tumour antigens may be limited to only a few of these antigens (the dominating ones).

Tumours express a large number of potential antigens (molecules in or on cancer cells that can be recognised by the immune system), but T cell responses to tumour antigens may be limited to only a few of these antigens (the dominating ones). These T cells could compete with any other T cells that have been, or are being, generated, preventing their expansion and development into fully functional T cells. If this is true, then tumours will 'escape' immune mediated destruction, as a T cell response to only a few antigens is not likely to be enought to seriously perturb growing tumours. In this grant we will use a well established mouse model of cancer to evaluate immune responses to tumour antigens during tumour growth and try to understand why other potential antigens do not invoke a fully functional immune response. If we are successful, we will have made advances that could lead to new therapies for cancer.Read moreRead less
Regulation Of T Cell Effector Function In Peripheral Tissues

Funding Amount
$698,550.00
Summary
Protection from infections relies on different types of immune cells. While some of these cells are found in the blood, others reside in peripheral tissues such as the skin. We will analyse the function of these peripheral immune cells to understand how they work to fight off infections. We will also investigate how so-called memory cells that permanently reside in peripheral tissues can protect from re-infection with similar bacteria or viruses.

Identifying The Ontogeny And Fate Of T Follicular Helper Cells By Two-photon Photoconversion

Summary
The aim of this proposal is to investigate immune cells called T follicular helper cells using a novel microscopy-based method that we have developed. This method lets us ‘tag’ these cells in a way that enables us to distinguish them from all other cells and follow them as they migrate to different immunological compartments during the response.

Characterisation And Development Of Type-2 NKT Cells

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.
Molecular And Cellular Control Of Human Th9 Cell Differentiation In Health And Disease

Funding Amount
$550,888.00
Summary
T helper 9 (Th9) cells are a recently defined population of CD4+ T cells that have been implicated in immunological disorders ranging from allergy, asthma, inflammatory bowel disease, and cancer, to host defence against fungal and parasitic infections. As such, Th9 cells are extremely important to human health and disease. This project aims to define the mechanisms involved in the generation, regulation and function of human Th9 cells.
The Impact Of Micropolymorphism Within The T Cell Receptor Genes And Their Target Antigenic Peptides
Funder
National Health and Medical Research Council
Funding Amount
$365,126.00
Summary
T lymphocytes play a pivotal role in the immune system by recognising virus-infected tissue through the use of highly specific T cell receptors (TCRs). This project will investigate the importance of genetic variation in the TCR genes in influencing how we fight infections. Another aim is to examine how the immune system tolerates genetic variation in an infecting virus. Advances in these areas will aid in the development of new "intelligent" vaccines.
The Mezzanine T Cell Response: Intervening At The Coal Face
Funder
National Health and Medical Research Council
Funding Amount
$765,585.00
Summary
In an initial immune response, specialised cells in lymph nodes tell T cells to multiply; the stimulated T cells depart and enter target tissue (e.g. lung in the case of flu). We describe a new response whereby the target tissue itself can tell T cells to multiply further. This response in target tissues reveals a new way of altering immune responses. This is especially important as in many diseases, the primary lymph node response has already occurred, so cannot be therapeutically intervened.
Investigating The Role Of TGF-beta In Resident Memory T Cell Induction And Maintenance

Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
