Summary
The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue in ....The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue injury observed and the speed of disease progression may be linked to the type of T cells recruited, their function, and their position in the liver. The aims of this project are to determine the factors involved in the fine positioning of T cells in the liver and establish a relationship between T cell recruitment, function, and progression of HCV disease in the liver.Read moreRead less
Dissecting The Role Of The Adipokine Leptin In Control Of The Inflammatory Response To Helicobacter Pylori

Summary
Helicobacter pylori is a bacterium that causes chronic gastric inflammation (gastritis), which may lead to cancer. Approximately 20% of Australians are infected. As part of the search for a human vaccine, we are attempting to understand the immune response against this bacterium. This study will investigate a novel observation that adipokines-small proteins produced by fat cells can regulate the actions of immune cells in the stomach and in this way determine whether vaccination works.
