title: CD4+ regulatory cells as a potential immunotherapy.
abstract: CD4(+) regulatory T (T(R)) cells represent a unique lineage of thymically generated lymphocytes capable of powerfully suppressing immune responses. A large body of experimental data has now confirmed the key role played by these cells in the maintenance of self-tolerance. Increasingly, the importance of these cells is also being recognized in a host of other clinically relevant areas such as transplantation, tumour immunity, allergy and microbial immunity. Additionally, it is also possible to generate T(R) cells by using a variety of ex vivo experimental approaches. We will focus here on harnessing the suppressive abilities of both these families of regulatory cells and how this should give us access to a potent cell-based immunotherapy appropriate for clinical application.
