Summary
Three hundred and fifty million people worldwide and 250,000 in Australia are chronically infected with hepatitis B virus (HBV). Without intervention, one third will die as a direct result of this infection through cirrhosis, liver failure and liver cancer, but current therapies are inadequate. New antiviral treatments requiring the identification of new antiviral targets are needed to combat the disease but a major obstacle to the study of HBV is the lack of a cell culture system.

Without intervention, one third will die as a direct result of this infection through cirrhosis, liver failure and liver cancer, but current therapies are inadequate. New antiviral treatments requiring the identification of new antiviral targets are needed to combat the disease but a major obstacle to the study of HBV is the lack of a cell culture system. As a result nothing is known about how HBV enter and fuses with the host liver cell but we have made significant progress with the identification of the entry and fusion events of the related duck hepatitis B virus, using the duck infection model. This knowledge is now ready for application to the medically important HBV by use of primary human liver cells and the techniques developed in the duck hepatitis B virus model.Read moreRead less

Summary
The viruses causing hepatitis in man must cross specialised cell layers in the body to reach the liver, and must again cross these cell layers and liver cells in order to be transmitted to subsequent hosts. This research will examine how each of the hepatitis viruses (HAV to HEV) are able to enter and exit the body, and the role that these mechanisms may play in the development of acute disease and of chronic infections with hepatitis B and C viruses.

Summary
Hepatitis B virus (HBV) causes acute and chronic infection leading to severe liver damage in many patients and increased risk of primary liver cancer. Worldwide ~350 million people have chronic HBV infection and, while a HBV vaccine is available that protects against new infections, current antiviral drug treatments for existing infection are largely ineffective. Thus, the aim of our project is to develop new treatments for chronic HBV infection using vaccination approaches.

Worldwide ~350 million people have chronic HBV infection and, while a HBV vaccine is available that protects against new infections, current antiviral drug treatments for existing infection are largely ineffective. Thus, the aim of our project is to develop new treatments for chronic HBV infection using vaccination approaches. These therapies will be tested in ducks infected with the duck hepatitis B virus (DHBV), a model for human HBV infection. In brief, DHBV-infected ducks will be treated with a new antiviral drug, Entecavir (ETV) developed by Bristol-Myers Squibb, which blocks virus replication. To accelerate clearance of infected cells before drug-resistant viruses can emerge, the ducks will also be treated in combination with different novel therapeutic vaccines designed to induce strong humoral and cell mediated immune responses. Based on outcomes in initial experiments, we will adjust the vaccination protocol in ETV-treated ducks to maximize reductions in the levels of DHBV in liver and bloodstream, rates of death and clearance of DHBV-infected hepatocytes. Our ultimate goal is to define a protocol for combination antiviral and vaccination treatments that allows elimination of HBV infection, or that achieves a level of control of infection that eliminates ongoing disease by reducing virus loads to virtually undetectable levels.Read moreRead less

Without intervention, one third will die as a direct result of this infection through cirrhosis, liver failure and liver cancer, but current treatments are inadequate. A major obstacle to the study of this virus is the lack of a cell culture infection system. We have used the duck hepatitis B virus (DHBV) model to study the events leading up to assembly of the virus in a way which prepares the viral envelope or outer coat for its foray into a new host cell. The project will examine the specific interactions of two proteins, the large and the small envelope protein, in addition to a third envelope protein we have recently discovered, which together make up the viral envelope. This will reveal which envelope components are required to make up the specific structures known to be essential for the disruption of the host cell membrane and subsequent entry of the virus to a new cell. An understanding of the changes that occur to the viral envelope upon entry will enable development of strategies for the inhibition or blocking of this change, thus identifying targets for the development of new antiviral agents. Because HBV is just one of many viruses which have an envelope, all of which must enter the cell in some way, our studies of HBV will also provide new clues with respect to the replication of other viruses such as measles, influenza and HIV. A related part of the study will examine the orientation of the large envelope protein within the virus particle and how it changes its orientation to assume its many important functional roles, in the late stages of particle assembly. Expanding on our finding that the small protein is essential to the orientation of the large protein, this study will reveal the mechanism of a unique method of protein transport which may have wider implications in cell biology.Read moreRead less

Summary
Chronic liver diseases, particularly those caused by Hepatitis B virus and Hepatitis C virus infection, are major causes of morbidity and mortality in our community. They are characterised by progressive scarring of the liver which finally leads to liver failure and the need in many cases for organ transplantation. We have identified a key molecule Fibroblast Activation Protein (FAP) that may play a key role and the process of liver fibrosis (scarring).

They are characterised by progressive scarring of the liver which finally leads to liver failure and the need in many cases for organ transplantation. We have identified a key molecule Fibroblast Activation Protein (FAP) that may play a key role and the process of liver fibrosis (scarring). The aims of the project are four fold: (1) To characterise where and on what cells FAP is produced in the liver and whether FAP levels correlate with the development of fibrosis in human chronic liver diseases caused by either Hepatitis B or Hepatitis C virus infections. (2) To examine a mouse strain in which the FAP molecule is knocked out ie absent. This will tell us whether FAP itself is essential for the development of fibrosis. (3) To isolate the cells within the liver that make FAP and to examine how particular functions of these cells are modified by FAP. (4) To find out what particular molecules FAP acts upon to perform its functions. The achievement of these aims will greatly increase our understanding of this key enzyme and its role in chronic liver injury. This work can potentially lead to the development of specific inhibitors of FAP function designed to relieve liver damage.Read moreRead less

Summary
Our robust ability to mount an immune response and clear infections is tempered by the possibility of promoting autoimmunity. Several host genes regulate immunity. Viruses like HIV have exploited these to abrogate antiviral immunity. This project attempts to define host factors that promote chronic infection. This will be extremely valuable in understanding the vulnerabilities of our immune system and provide an insight into how we can treat chronic infections.
