Summary
This research will begin to determine the significance of changes in the amount of a recently-discovered protein on the surface of tumour cells. We have shown that an increase in expression of this protein protects tumour cells from destruction by our immune system's killer T cells. The outcome of this research could lead to a better understanding of how the immune system recognises and kills tumour cells, and ultimately, alternate vaccine strategies for tumours.

Summary
This research will determine the biological role of a protein of unknown function that is likely to participate in movement of white blood cells through the body. The outcome of this research will increase our basic knowledge of how the immune system functions and could lead to alternate therapeutic strategies for the control of autoimmune diseases.

Summary
The immune system is essential for protecting us against invasion from without by viruses and bacteria and invasion from within by cancer cells. Among the white blood cells making up this system are those responsible for producing antibodies. To ensure that all possible infections and tumours can be recognised, the body needs to manufacture a very large number of these cells on a continuous basis.

Among the white blood cells making up this system are those responsible for producing antibodies. To ensure that all possible infections and tumours can be recognised, the body needs to manufacture a very large number of these cells on a continuous basis. The aim of this project is to work out the mechanism responsible for controlling their production and function using a novel experimental system. By pinpointing the different stages involved in antibody production in the normal host we should be in a better position to make longer lasting vaccines in the future and to understand what goes wrong with these white cells in disease. In particular, the results should shed light on the chronic form of leukaemia called myeloma and some of the autoimmune disorders like the rheumatic diseases which occur when the antibodies being produced attack our own tissues.Read moreRead less

Summary
Special white blood cells called dendritic cells teach the immune system to fight cancer and are a key component of therapeutic cancer vaccines. We identified a subtype of human dendritic cell that is predicted to be the most effective at mounting anti-cancer immune responses. We developed a novel antibody specific for these dendritic cells that can be used to deliver the vaccine directly to them and will use this to construct and validate a novel vaccine for cancer and viral infections.
We will construct different genetically engineered viruses, which infect cells in the respiratory tract, to deliver genes encoding proteins from human immunodeficiency virus (the AIDS virus). These engineered viruses can be expected to generate an active immune response in mucosal tissues, including the vaginal and rectal tracts. As these are the major routes for transmission of the AIDS virus, these new vaccines are expected to reduce transmission of the AIDS virus.
