Summary
As liver cancer risk correlates with increased liver stem/progenitor cell numbers, therapies that reduce their numbers will reduce cancer development. On the contrary, therapies to increase progenitor cell numbers will assist their use in cell therapy-based approaches or artificial liver devices to treat chronic liver disease. This project will determine how to use inflammatory cells to manipulate progenitor cell numbers.
Pathophysiology Of Functional Dyspepsia: Integration Of Upper Gut Function, Inflammation And A Systems Biology Approach.

Summary
Functional dyspepsia (FD) is an extremely common and costly problem with no cure. We and others have found that inflammation and immune activation play a role in FD but to date no studies have linked these findings with well known diseases markers including disordered sensory and motor function or psychiatric comorbidity. This study will explore the interrelationships between inflammatory and immune mechanisms, disease markers as well as the microbiome. This study could unravel the cause of FD.
Liver damage after liver surgery or shock is called ischemia-reperfusion injury (IRI). Recovery after surgical removal of liver tissue is due to liver regeneration. IRI and liver regeneration are controlled by specialised proteins called cytokines, one of which, TRAIL, is essential for both IRI and liver regeneration. This research is to find out how TRAIL exerts such seemingly opposite effects. The aim is to learn how to protect the liver against damage, and to stimulate its recovery.
Role Of Tissue Ferritin As A Proinflammatory Mediator Of Hepatic Stellate Cell Activation In Hepatic Iron Overload.

Summary
The hepatic stellate cell is responsible for liver scarring (fibrosis) in chronic liver diseases such as the iron overload condition Haemochromatosis. Our research has identified a role for tissue-derived ferritin as a proinflammatory cytokine in hepatic stellate cell biology. This proposal will examine the mechanisms associated with ferritin's proinflammatory action and assess its role in the fibrosis which occurs in Haemochromatosis.

Summary
About one third of the population have a fatty liver, and this greatly increases risks of liver failure after liver surgery or when fatty donor livers are used for transplantation (such organs are currently disposed of). The disease process is called ischemia-reperfusion injury (IRI). The investigators have recently shown that both fibrates and statins provide partial protection against IRI in fatty livers. This research is directed at establish the protective mechanisms, and whether combination ....About one third of the population have a fatty liver, and this greatly increases risks of liver failure after liver surgery or when fatty donor livers are used for transplantation (such organs are currently disposed of).

Summary
Gastric cancer is a major cause of morbidity and death worldwide. We have previously established a very informative animal model of this disease which has facilitated a new understanding of the diverse role of the IL-6 family of cytokines in regulating gastric tumour growth and dissemination to distant organs. This proposal will focus on how the main members of this cytokine family, namely IL-6 and IL-11, inhibit gastric tumour invasion to other organs, and promote tumour growth respectively .

This proposal will focus on how the main members of this cytokine family, namely IL-6 and IL-11, inhibit gastric tumour invasion to other organs, and promote tumour growth respectively . An understanding of these processes will aid in designing therapeutic interventions specific for each cytokine and which may lead to drugs aimed at limiting or reversing this disease.Read moreRead less
Immune Activation In Functional Gastrointestinal Disorders

Summary
Up to 30% of Australians are estimated to suffer from Functional Gastrointestinal Diseases such as Irritable Bowel Syndrome and Functional Dyspepsia, but the cause of these chronic diseases is unknown. Alterations in the immune system are increasingly suggested, but little is known about how this leads to the debilitating symptoms of discomfort and pain. This project combines immunology studies with neuroscience to determine the key mediators involved and how they communicate with nerves.
Exploring The Mechanisms Of Generation Of Intestinal TH17 Responses And The Mechanisms Of TH17 Mediated Pathology

Summary
Our research recently described a mouse that shows excellent similarities to human inflammatory bowel diseases. We further show that the disease mediating substances called cytokines are also similar between our mouse and UC. Particularly, a recently described network of cytokines that are the major mediators of disease in our mice and human IBD. This project examines how we can best interfere with the actions of these cytokines to treat and prevent intestinal inflammation.
