Summary
Australian Indigenous children experience extreme rates of acute lower respiratory infection (ALRI) that medical interventions have failed to reduce. Vitamin D is an important immunoregulatory molecule of the respiratory system that remains uncharacterised in this population. We propose that deficiency contributes to the persistent rates of ALRI. This study will characterise vitamin D levels in a cohort of Indigenous children with and without ALRI. The results will guide future intervention.
To Describe The Regional Differences In The Innate Immune System Of The Skin Using Intra-vital Multiphoton Microscopy And Understand Its Functional Consequences In A Cutaneous Parasite Infection Model.

Summary
This study is the first of its kind to map the innate immune system, the body's first line of defence, in the skin - coined the "immune atlas". Researchers have shown regional differences in innate immune cells which could explain how infections develop at different sites of the body. Although they have shown this in a cutaneous leishmaniasis model, a parasite endemic in most parts of the world, it may have implications also for inflammatory skin conditions such as eczema or psoriasis.
Investigating The Role Of TCR Avidity In Influenza Virus-specific CD8 T Cell Responses

Summary
One of the constituents of the immune system is the cytotoxic, or killer, T cells and these are important in the overall protection from viral infection. Activation of these T cells is mediated by signalling through the T cell receptor (TCR). This study will definitively determine how the strength with which the TCR binds to the activating ligand, can influence the quality of virus-specific T cell immune responses after infection. This has implications for vaccine design.
Immune Correlates Of Protection Against HCV - A Potential Role For NK Cells And NKR Expression On T Lymphocytes

Summary
Hepatitis C virus (HCV) poses a major public health problem with ~200 million people infected worldwide and no available vaccine. Injecting drug users (IDUs) are the major risk group, with 75% of infected individuals progress to chronic infection, which can then lead to liver cirrhosis and hepatocellular carcinoma. However, about 20% of a given cohort of IDUs remains uninfected. This project is therefore focused on understanding the innate immune mechanisms behind this protection.
The Role Of Novel G-Protein Coupled Receptors In Immunity And Inflammatory Diseases

Summary
Recent advances in molecular biology techniques have resulted in the identification of many novel GPCRs. Novel GPCRs expressed selectively on immune cells display a potential target for novel therapies for inflammatory diseases such as Asthma and Rheumatoid arthritis. This project aims to define the activity and significance of a novel group of GPCRs, the GPR40 family. Outcomes of this project will be further understanding of immune cell development and inflammatory disease development.
