Tissue-specific antigens are expressed in the thymic medulla under the influence of the AIRE gene, suggesting that unresponsiveness to these peripheral antigens is a result of central tolerance.

It occurs in three forms: central tolerance, peripheral tolerance and acquired tolerance. Central tolerance is immunological tolerance developed during T and B

Moreover, it is the backup precaution of the immune system as central tolerance is not perfect and some self-reactive lymphocytes find their way into the periphery and secondary lymphoid tissues. We have recently shown that this peripheral tolerance induction protocol also permits the establishment of hematopoietic chimerism and generation of central tolerance if bone marrow is transplanted during costimulation blockade and donor‐specific skin allografts are transplanted 8 weeks later . Peripheral tolerance is the second branch of immunological tolerance after central tolerance. It occurs on the immune periphery (after the exit of T and B cells from the primary lymphoid organs). Its main purpose is to ensure that self-reactive T and B cells, which have avoided central tolerance, do not cause autoimmune disease. [1] Start studying Central and peripheral tolerance.

3. Peripheral Tolerance – Role of BAFF (BLyS) The central tolerance mechanisms eliminate approximately 90% of the self-reactive B cell pool [5,22]. Despite the presence of clonal deletion, anergy and receptor editing mechanisms, several autoreactive clones bypass these checkpoints and are found in peripheral B cell pool [8,23,24].

Although central-tolerance mechanisms are efficient, they cannot eliminate all self-reactive lymphocytes, in part because not all self-antigens are expressed at the primary site of lymphocyte development—the thymus. Peripheral tolerance is the second branch of immunological tolerance, after central tolerance.

Central tolerance prevents the maturation and egress of autoreactive immune cells, for example via clonal deletion of T cells in the thymus 1. Any autoreactive cells that escape central tolerance and migrate to the periphery would then encounter mechanisms of peripheral tolerance, for example the induction of anergy or suppression by mechanisms of action of regulatory T cells 2 (Figure 1). Thus, peripheral tolerance processes exist wherein self-reactive T cells become functionally unresponsive (anergy) or are deleted after encountering self-antigens outside of the thymus.
