Summary
Optimal transport of sodium and chloride ions is essential for the maintenance of electrolyte balance, blood volume, blood pressure and lung function. We are studying the control of a key sodium channel (the epithelial sodium channel) and a key chloride channel (cystic fibrosis transmembrane conductance regulator) by an enzyme called Nedd4-2. This project will enable us to understand how Nedd4-2 regulates these two ion channels and to study the pathological consequences of the loss of Nedd4-2.
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
