Peripheral tolerance is any mechanism that limits the activity of an immune response, excluding mechanisms in the bone marrow and thymus where immune cells are initially developed. The body uses a few peripheral tolerance mechanisms including the use of T regulatory cells, clonal anergy and exhaustion, and clonal deletion.

Peripheral Tolerance (occurs after lymphocytes leave the primary lymphoid organs. 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. Recent advances in mechanistic studies of central and peripheral T-cell tolerance are promoting the development of therapeutic strategies to treat autoimmune disease and cancer and improve transplantation outcome. When self-reactive T cells escape into the periphery, peripheral tolerance ensures that they are deleted or become anergic (functionally unresponsive to antigen). Peripheral tolerance can occur through one of three mechanisms: Induction of anergy (a state of inactivation in which the lymphocytes remain alive but are unable to respond to antigen). Peripheral tolerance is the second branch of immunological tolerance, after central tolerance. It takes place in the immune periphery (after T and B cells egress from primary lymphoid organs ).

The role of clonal deletion and T-cell anergy in maintaining peripheral tolerance has been demonstrated in several in vivo models. 5,6 More recently, the roles of Foxp3 + and LAG-3 + regulatory T cells in peripheral tolerance has been better defined. 7,8 Likewise, cell-surface receptors such as CTLA-4 and PD-1 and cytokines such as interleukin (IL)-10 and transforming growth factor (TGF)-β
