Summary
HIV weakens the immune system causing AIDS, but the mechanism by which HIV does this are poorly understood. This proposal aims to define these mechanisms. We expect that HIV evolves in infected people, becoming better able to infect and kill cells of the immune system, and that this results from specific genetic changes in the virus. This study will contribute to a greater understanding of how HIV causes AIDS, which is necessary for the development of new drugs to treat HIV infection.

Summary
G protein-coupled receptors are specialised proteins on the surface of cells. They are the targets of 30% of currently available pharmaceuticals. This proposal will examine exciting and novel properties of these proteins that only occur following their assembly into specialised networks in cells. The use of cutting-edge technology will allow us to understand the role of these networks in many diseases. The new information will expand our current knowledge, and facilitate targeted drug design.

Summary
Epstein-Barr virus, (EBV) is a human herpesvirus associated with a range of human cancers. EBNA1, an important EBV antigen, was thought to be “immunologically silent” however, recent studies from our laboratory show that EBNA1 is recognized by our body's defence system and these observations raise the possibility that EBNA1 may be an exploitable, immuno-therapy target for treating EBV-associated cancers.

Summary
CD46 is a protein on human cells that viruses and bacteria bind to during infection. Our laboratory has found that binding of CD46 on immune cells impairs their ability to recognize and kill target cells and may explain the immunosuppression caused by measles infection. We aim to investigate the mechanisms behind the effect of CD46 on immune cells. The outcomes of this study will define new paradigms in lymphocyte biology and determine how CD46 influences the immune response to infection.
