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.
Developmental Vitamin D Deficiency And Prefrontal Cortical Dysfunction

Summary
The cause of schizophrenia is unknown but is believed to be due to abnormal brain development. Dopamine abnormalities are central to schizophrenia. We have developed a model of maternal vitamin D deficiency in rats, based on disease epidemiology that shows individuals that have low levels of vitamin D at birth have an increased risk of developing schizophrenia later in life. We now also show dopamine systems in regions associated with cognition may develop abnormally in our animal model.
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. T follicular helper cells are important for protective immune responses against pathogens and a better understanding of this T cell subset will aid vacc ....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.

The Developmental Vitamin D-deficiency Animal Model Of Schizophrenia:- Critical Window For Intervention And Optimal Dose

Summary
We have established that low levels of vitamin D at birth increase the risk of children developing schizophrenia in later life. Our studies indicate this risk is dose-dependent and may be enhanced if developmental vitamin D (DVD) deficiency is extended into postnatal life implying there may be an early critical vitamin D threshold and a critical window of exposure required to avert schizophrenia. This project will examine this and the effects of supplements using our DVD-deficiency animal model.
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

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.
Do The Developmental Vitamin D-deficiency And Maternal Immune Activation Animal Models Of Schizophrenia Have Convergent Early Pathways ?
Funder

Funding Amount
$669,580.00
Summary
The etiology of schizophrenia is unknown but it is generally considered to have a neurodevelopmental basis and involve altered dopamine signaling. Using two distinct developmental animal models of schizophrenia we have shown convergent gestational abnormalities in how dopamine systems develop. This is possibly a convergent early etiological mechanism in schizophrenia.
