B-cell Peripheral Tolerance. Peripheral tolerance mechanisms (in secondary lymphoid tissues) exist for various reasons: Imperfect T-cell tolerance: in most autoimmune diseases, B-cells are T-cell dependent, requiring help from pre-activated cognate autoreactive T-cells; T-independent B-cells can be activated by autoantigens without T-cell help

Peripheral tolerance mechanisms limit autoimmunity by constitutively eliminating self-reactive CD8(+) T cells from the periphery in a process called deletion.

While the most important form of tolerance is non- reactivity to self antigens, it is possible to induce tolerance to non-self antigens. When an antigen induces tolerance, it is termed as Tolerogens. Tolerance is different from non-specific immunosuppression and immunodeficiency. It is an active antigen-dependent process in response to the antigen. 4. 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 … Peripheral Tolerance 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 mechanisms limit autoimmunity by constitutively eliminating self-reactive CD8(+) T cells from the periphery in a process called deletion. Autoreactive B cells that escape central B cell tolerance are controlled by peripheral tolerance mechanisms that differ slightly from those discussed previously for autoreactive T cells. If an autoreactive B cell encounters self antigen in the periphery, it receives signal 1 but still depends on an antigen-specific Th effector cell to deliver signals 2 and 3.

Platelet-specific gene therapy can promote antigen-specific immune tolerance through peripheral clonal deletion of antigen-specific CD4 and CD8 T cells and the expansion of antigen-specific Treg cells even with pre-existing immunity.

Peripheral tolerance: The occurrence of peripheral tolerance takes place when the mature lymphocytes that recognize self-antigens loses its ability to respond to that antigen, or lose their viability and become short-lived cells, or are induced to die by apoptosis. The importance of peripheral tolerance is listed as: POSITIONAL TOLERANCES.
