✦ Synopsis

Despite the acceptance of principles such as clonal deletion in the thymus and peripheral clonal anergy, several new issues have arisen in the study of T-cell tolerance. For example, in the case of thymic tolerance, it is now clear that several distinct components of the thymus, including various subsets of thymic epithelial cells, can all make contributions to the deletion of autoreactive T cells. In the case of peripheral T-cell tolerance, the induction of anergy now has been complicated by the possibility that bone marrow derived antigen presenting cells may, under certain conditions, be tolerogenic rather than stimulatory.

T-cell tolerance to self antigens is maintained by events that occur within the thymus and in the periphery. Mechanisms that operate on immature T cells within the thymus are effective in induction of tolerance to viruses, but mechanisms of tolerizing mature T cells are likely to break down. This fa

## Abstract The immune system uses several mechanisms of central and peripheral tolerance in order to prevent the activation of T lymphocytes toward self‐antigens. Although the importance of immune self‐tolerance has been established for a long time, some essential cellular and molecular mechanisms
