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.
Mammals have evolved an array of mechanisms to sense microbes. These immune sentinels must distinguish self from non-self to activate an immune response. The initiation, amplification and quenching of an immune response is carefully orchestrated to eliminate invading pathogens while minimising collateral damage to host tissues. This research focuses on proteins that prevent inflammatory diseases such as cardiovascular disease, hepatitis, inflammatory bowel disease and skin diseases.

Summary
Inflammation occurs as part of the body's natural defenses against infection or injury, but can be damaging when unregulated and can lead to cancer. Although the protein factors critical for inflammation have been carefully studied it remains unknown how ribonucleic acid (RNA) molecules can modify and regulate inflammation. This project will identify RNA molecules that control inflammatory signalling, and further translate these findings to show they contribute to the progression of cancer.
Dendritic Cells In Innate Immunity And Their Potential Clinical Manipulation

Summary
Dendritic cells (DC) are rare cells that are crucial in response to infection and surveillance of damaged tissues. We aim to understand the tools that are expressed by DC that allow them to sense pathogens and the functions of different DC types once a pathogen has been detected. The ultimate aim is to be able to understand and harness the functions of different DC so that we may directly target them upon demand to aid in the course of infection or potentially as tumour therapy.
