Summary
Obesity and type II diabetes are epidemic diseases in Australia. Gut-derived hormones are key mediators in these diseases, due to their role in regulating appetite and blood glucose levels. Therapeutic modulation of these hormones also provides significant benefits for patients. In this proposal, we will determine the metabolic functions, such as appetite control, for a previously uncharacterised hormone, which is an unexplored therapeutic target for obesity and diabetes.
Wheat Proteins, The Duodenal Microbiome And Immune Activation In The Aetiopathogenesis Of Non-coeliac Gluten Sensitivity And Functional Dyspepsia

Summary
Functional dyspepsia, characterised by troublesome pain in the upper abdomen, or an inability to finish a regular sized meal, is common, affecting up to 15% of Australians. There are no effective treatments. This project will evaluate the role of diet, in particular wheat, as a driver of the subtle inflammation and disturbances in the microbiome seen in the small intestine of functional dyspepsia patients, and test whether a gluten or wheat free diet is an effective treatment option.
Hormone Transport By Alpha-2-Macroglobulin: Novel Roles In Regulating Hormone Activity

Summary
Alpha-2-macroglobulin is a large protein in the blood known to bind and transport numerous hormones in the circulation. Our previous studies published in BLOOD (2009) and JBC (2013) have discovered an important role for this molecule in the transport and regulation of a peptide hormone. The studies proposed in this application have important implications for understanding new roles of alpha-2-macroglobulin in hormone binding and regulating the activity of hormones in disease states.
Crohn’s disease (CD), an inflammatory disorder of the gut, is thought to result from an inappropriate response to an environmental trigger, likely gut bacteria. This project will assess differences in microbial communities and host gene expression of early- and late-stage CD tissues. A greater understanding of the differences in mucosal gene expression induced by specific bacteria may provide insights into the pathophysiology of CD, and could conceivably guide therapeutic choices in the future.

However, the task of developing a vaccine against H. pylori remains important. Vaccination is the most effective mechanism to prevent disease associated with this infection, particularly gastric cancer, one of the most common causes of cancer death world-wide. However, current attempts to develop an effective vaccine for humans has been limited by the non-availability of an effective and safe adjuvant. The aim is to construct a recombinant Virus-Like Particle which can be used as a safe and effective vaccine against Helicobacter pylori infections. We specifically aim to: · determine the most efficacious singular or combinatorial route-s of delivery of Virus-Like Particles (VLPs) which will induce the desired Th2 and B cell responses in mice · define the Th2 and B cell epitopes of H.pylori Kat A carboxyl terminus that can be used to construct chimeric HBsAg-S-Kat A VLPs · determine if the induction of desired immunological responses in mice are protective against wild type challengeRead moreRead less
