Summary
Interleukin 21 is a molecule which activates B cells. Defects in this pathway cause immunodeficiency where individuals cannot make antibodies, while constant activation has been reported in mouse models of autoimmunity. Examining these pathways will shed light on the causes of human immune disease, and may reveal molecules that could be targeted for the treatment of immunodeficiency and autoimmunity. Amplification of normal immune responses could lead to the development of improved vaccines.
Hepatitis B In The Top End Of The Northern Territory: Epidemiology, Burden Of Disease And Health Literacy Among Those Affected.

Summary
I am an Infectious Diseases doctor working with Hepatitis B in the Top End of the Northern Territory. I will provide detailed information about the prevelance of Hepatitis B infection, the specific subtypes found in this region and the burden of disease attributable to it. This information is not currently available for this region. I will also explore the levels of knowledge in the community about Hepatitis B infection using this information to develop and evaluate an educational tool.
Hepatitis B Virus Drug Resistance: Impact On The Immunisation Program

Summary
ñAntiviral drug-associated vaccine escape mutantsî have the potential to jeopardize the hepatitis B immunization program. Which particular viral mutations or combination of mutations that can directly affect the clinical outcome of infection, especially in the context of vaccine induced immunity, are not known. In this study we will identify the clinical sequelae and public health consequences arising from the selection of these mutants.
Dynamic Imaging Of The Immune Response In Lymph Nodes By Two-photon Microscopy

Summary
Despite the enormous contribution of vaccination to the prevention of human disease and suffering, little is known about the laws that govern the selection and survival of B cells during the response to infection or vaccination. Our research projects aim to integrate several cutting-edge technologies, including two-photon microscopy, in order to understand the cellular and molecular basis of immunity.
The Role Of Stellate Cells In Fibrosis And Liver Disease Progression In HIV-Hepatitis B Co-infection

Summary
Liver related mortality is the commonest cause of non-AIDS death in HIV infected individuals on treatment. With HIV, HBV liver damage is accelerated and liver-related mortality increased. Understanding how and why is critical to management. I will examine the role of hepatic stellate cells using in vitro models and directly ex vivo from infected patient biopsy tissue. I will investigate the activated of these cells by HIV and HBV infection, thus promoting scar formation with liver injury.
Clearing Chronic Infectious Diseases – Enhancing Host Immune Effector Function

Summary
Chronic infections produced by pathogens such as HIV, overwhelm our immune system leading to an exhausted state where cells responsible for the clearance of invading microorganisms are unable to respond effectively. We have recently identified a highly promising therapeutic target that enhances immune effector function. We seek to understand the underlying mechanism, and to explore the therapeutic potential of this approach for the treatment of a broad range of pathogens, including those respons ....Chronic infections produced by pathogens such as HIV, overwhelm our immune system leading to an exhausted state where cells responsible for the clearance of invading microorganisms are unable to respond effectively.

Summary
Hepatocellular carcinoma (HCC) is the most common primary liver cancer and worldwide is the third and fifth leading cause of cancer death in men and women respectively. Early diagnosis is vital to patient survival. Our research investigates new methods in the early diagnosis of HCC, including new protein markers of the cancer and non-invasive measurements of liver scarring. We also study the genetics of HCC and investigate new genes that could be targets for future therapies.
Development Of A Cultured Tissue Substitute To Repair The Ageing Retina

Summary
The ultimate goal of my research is to develop an effective, affordable and accessible treatment for patients afflicted with age related macular degeneration (AMD). The novelty of my study is that I will use a protein extracted from silk as a form of scaffold on which to grow new retinal tissue, with the view to replacing the damaged tissue that eventually leads to permanent loss of sight in AMD patients.
Investigating The Role Of TGF-beta In Resident Memory T Cell Induction And Maintenance

Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
