The cellular and molecular basis to the paradox of positive versus negative T cell selection [ 2000 - 2002 ]

Research Grant

Researchers: Prof Richard Boyd (Principal investigator)

Brief description The protection against disease requires the generation of white blood cells called T lymphocytes that are produced in the thymus. Each T cell has a specific surface receptor, generated by random gene switching, that can react against foreign pathogens. Since there is a very high conservation of molecules used in all organisms, some of these receptors could by chance also react against normal cells in the host. Eliminating all such self-reactive cells would mean, however, the repertoire remaining for eliminating infection would be too low and immunodeficiency develops. This project investigates the mechanisms controlling the balance between defence infection and the need to prevent immune-based self destruction termed autoimmunity.
