The role of the immune system in pain is emerging from recent discoveries, and may hold the key to novel pain treatments. Most people experience brief gut infections from food or contagion without long-term consequences. Many others suffer symptoms for years afterwards - probably the best example of immune-based pain. Our project investigates how immune cells communicate with sensory nerves, and how these communications change from both angles after gut infection or inflammation.
Cell Surface Mucins In Gastrointestinal Infection, Inflammation And Cancer Development

Funding Amount
$469,627.00
Summary
Cell surface mucins are protective molecules that line all the wet surface of the body, including the gastrointestinal tract. Our research has uncovered that mucins regulate cell growth and cell death. Inappropriate control by the mucins, could lead to chronic inflammation and formation of cancers. We will test how important these molecules are in the development of cancers in the intestine, and further explore the mechanism of action.
Transient Receptor Potential Channels (TRPs) As Transducers And Targets In Primary Visceral Afferents

$669,130.00
Summary
Transient receptor potential, or TRP channels, are involved in generating many of the sensations we perceive, such as heat, cold, touch and pain. Some TRP channels are specialized to signal pain from visceral organs, which we must investigate if we are to find treatments for visceral pain, which are currently lacking.
Strain-level Characterisation And Visualisation Of The Mucosal Microbial Communities Associated With Inflammatory Bowel Disease (IBD) For The Development Of Novel Biotherapeutics
Funder
National Health and Medical Research Council
Funding Amount
$1,181,878.00
Summary
Australia has one of the highest incidence rates in the world of Inflammatory Bowel Disease (IBD), a debilitating inflammatory condition of the gastrointestinal tract. Cutting-edge molecular and visualisation technologies will be used to examine the role of the gut microbiome in IBD, and identify specific members of this community to be used as new therapies to suppress inflammation and improve outcomes for patients with IBD.
Recycling Endosomes Governing Cell Polarity And Cytokine Secretion.

Funding Amount
$958,412.00
Summary
Cytokines are chemical messengers released by cells to mount inflammatory responses to fight infections. The timing and direction of cytokine release must be tightly regulated. We investigate the cellular compartments and molecules that control cytokine secretion using sophisticated live cell imaging. Uncontrolled cytokine release is the main cause of ongoing inflammation in arthritis and inflammatory bowel disease and our studies aim to identify cellular targets for new drug development.
Regulating The Secretion Of Inflammatory Cytokines

Summary
Cytokines or chemical messengers released by cells are essential for controlling immune responses but, in excess, they cause Crohn's disease and arthritis. Our research aims to block cytokine release as a novel way to ameliorate disease. We have identified specific cellular proteins, called golgins, that can be targeted to reduce cytokines. Here, characterization of golgin mediated cytokine transport in cells and in a mouse disease model is necessary to translate these findings for human benefit
Quantitiative Assessment Of Solar UV Exposure For Vitamin D Synthesis In Australian Adults

Funding Amount
$1,162,536.00
Summary
This research program will add significantly to our current scientific understanding of the dual health outcomes of UV exposure (Vitamin D and skin cancer) . This project is in line with Australia's R and D Priorities, in that it will result in direct and indirect social and economic benefits to Australia by applying the scientific knowledge gained through this research to develop public health initiatives to improve some of Australia's most significant and costly health problems.
The D-Health Trial: A Large-scale Population-based Trial Of Vitamin D Supplementation For Improving The Health Of Older Adults
Funder
National Health and Medical Research Council
Funding Amount
$2,591,860.00
Summary
The D-Health Trial is a randomised placebo-controlled trial of vitamin D supplementation for improving the health of older Australian adults. Over 21,000 people were recruited and randomised to monthly doses of vitamin D or placebo. This grant will enable completion of the planned 5 years of supplementation and long-term follow-up of mortality and cancer. The results of the trial will inform decisions about food fortification and/or supplementation with vitamin D.
There is a need for a greater understanding of the complex relationship between sun exposure and the production of Vitamin D. This study will expand on the recently-completed AusD study to examine how personal, behavioural, and environmental factors impact on intra-individual seasonality in Vitamin D production. The study findings will guide the development of specific, evidence-based public health recommendation that balance the risks and benefits of sun exposure.
A Practice Change For Patients With Severe Chronic, Clinically Unexplained Gastrointestinal Symptoms: A Randomised, Controlled Intervention To Assess Efficacy And Cost-effectiveness
Funder

Funding Amount
$1,276,080.00
Summary
Unexplained chronic gastrointestinal symptoms are extremely common and costly to the health system. Currently patients are managed in the hospital setting with the 'typical' face-to-face office-based model which sees the clinician spending valuable time gathering information and often treatments (e.g. allied health) delivered in a non-standard way. This project will evaluate the effectiveness of a new standard best-practice clinical model with a structured technology enabled management approach.
