Summary
The malaria parasite P. falciparum infects red blood cells and makes the cells put on their surface a protein called PfEMP-1. The parasite can effectively “hide” by constantly changing this protein and making it unrecognizable by the immune system. PfEMP-1 can also suppress the immune system so that it can’t respond adequately to infection. Therefore, understanding PfEMP-1 function is important. I will investigate how PfEMP-1 can do this by looking at its cross talk with the immune system.
Treating and preventing painful fractures could be improved by strengthening cortical bone – the hard outer shell of all bones in the skeleton. We don’t know how cortical bone forms, but if we did, we could improve its strength. We have found that a brain-like network of cells inside the skeleton, called osteocytes, use a specific signal, called SOCS3, to make strong cortical bone. This study will find out how SOCS3 works and find new ways to make cortical bone strong and healthy.
A New Master Adaptor Protein For Toll-like Receptor Signalling

Summary
Certain proteins on the surface of cells are able to sense danger and infection. These receptors use adaptor proteins to enable cells to respond appropriately. We have discovered a new adaptor that controls receptor signalling in inflammation. This new master adaptor likely has widespread roles in infection and inflammation. We aim to understand how this adaptor works, and to identify ways of blocking its actions. These studies may help us to control inflammation underpinning many diseases.
Defining The Role Of The Novel Gene MUL1 In Antiviral Innate Immunity

Summary
Uncontrolled immune responses can clinically manifest in chronic inflammatory disorders. Viral infections carry a significant global health burden, causing acute and chronic inflammation. This study will characterize a novel regulator of anti-viral immune responses. Understanding the regulation of infection models may provide the means of manipulating immune responses to control infections and provide better health outcomes.
Interferon Regulatory Factor 6: A Novel Epithelial-specific Regulator Of Mucosal Inflammation

Funding Amount
$517,989.00
Summary
Epithelial cells lining the respiratory and gastrointestinal tracts play pivotal roles in protecting us from infection. Inflammatory factors released by epithelial cells are important for fighting infection; however, they also contribute to chronic inflammatory diseases. We aim to understand how a protein called IRF6 regulates the inflammatory response of epithelial cells. The knowledge gained will identify new therapeutic approaches for inflammatory diseases.
Profiling Global Inflammatory Signatures For GPCRs In Human Macrophages

Funding Amount
$687,770.00
Summary
Macrophages are important white blood cells of the immune system. They trigger inflammatory responses to infection or injury, but prolonged inflammatory responses can lead to chronic diseases. In this project we aim to better understand how macrophages sense the outside environment, how external signals trigger inflammatory processes, how this leads to diseases such as autoimmune and inflammatory diseases, cancer and cardiovascular diseases, and how to control them with drugs.
Understanding The Role Of The Atypical Cadherin Fat4 In Lymphatic Vascular Development

Funding Amount

Summary
This application will define the role of a large cell adhesion molecule, FAT4, in lymphatic vascular development. By understanding how FAT4 functions in lymphatic vessels, we will gain insight to the mechanisms by which mutations in the gene that encodes this protein cause a human lymphoedema syndrome.
T cells play a central role in the immune response. The primary event in T cell activation is the triggering of a specific T cell receptor (TCR). Our studies will define new mechanisms for the regulation of TCR-mediated T cell responses. Our studies may yield novel insight into processes that contribute to the development of type 1 diabetes & inflammatory bowel disease.

Interrogating the adaptive potential of skeletal muscle. Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing.

Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing. This project will provide fundamental new knowledge in understanding how modifying muscle attributes influence successful ageing. This knowledge will improve resilience, productivity, and wellbeing of all Australians, with implications for reducing societal and economic burden.Read moreRead less
Target Of Rapamycin control of nutrient uptake. This project aims to study nutrient uptake in eukaryotes. It is expected to generate new knowledge of critical and conserved features of environmental and Target Of Rapamycin (TOR)-mediated control of nutrient uptake, specifically endocytosis, building on novel preliminary data that identifies novel TOR control points. The expected outcomes include new insights into mechanisms controlling nutrient uptake and fostering institutional collaboration. T ....Target Of Rapamycin control of nutrient uptake.
