Abstract:
Hepatitis B virus (HBV) infection is an increasing public health problem in Australia particularly in certain 'high-risk' subgroups of the population. In order to establish cost-effective screening and vaccination programs directed towards the control and possible eradication of HBV infection, accurate information is needed about the modes of spread and the numbers of "at risk" individuals in particular community subgroups. In addition, treatment strategies must be developed for established HBV carriers since at least 35% of such individuals will die directly related to complications of the di

Abstract:
Hepatitis B virus (HBV)-specific CD8+ T cells are critical for a successful immune response to HBV infection. These cells are markedly diminished in patients that are unable to contain the virus and the mechanisms contributing to their depletion are not well-understood. The aim of this work was to further dissect this response in individuals with chronic infection. Studies of the HBV-specific CD8+ T cell immunodominance hierarchy demonstrated that persistent infection was associated with a hyporesponsiveness that was exacerbated with increasing antigenic load.

Abstract:
Hepatitis B virus infection (HBV) is an important health problem worldwide, with a significant rate of chronic infection, which can lead to cirrhosis and hepatocellular carcinoma (HCC). Increased age is an important determinant of progression to cirrhosis and HCC, possibly because age is a crude measure of the duration of HBV infection. Increasing age is associated with changes in liver structure, blood flow and function and with reduced response to injury, impaired regeneration and increased mortality in acute liver disease. Age has been identified as a co‐factor in several chronic liver dise

Abstract:
Persistent infection with hepatitis B virus (HBV) is a global health burden accounting for more than a 1 million deaths worldwide. Much work has focused on the failure of the adaptive immune response in persistent HBV infection. In contrast innate responses remain poorly characterised. Accumulating evidence indicates the involvement of NK cells in the control of viral infections and shaping of adaptive immunity. Here we investigated the antiviral and immunoregulatory potential of NK cells in chronic Hepatitis B virus infection (CHB). The combination of immunosuppressive cytokines seen in CHB s
