Y1 - 1998. N2 - Peripheral tolerance to self proteins is induced because these antigens are presented to T lymphocytes under conditions that do not allow effective immune responses to develop, or because the responses of the specific T cells are tightly regulated. We then examined animals with paw inflammation induced by CFA, which leads to reduced baseline PPT (hyperalgesia) and to increased peripheral opioid analgesia (reviewed in ref.

Peripheral Tolerance. Peripheral tolerance mechanisms occur after mature lymphocytes are released into the lymph nodes or other tissues. These mechanisms are intended to prevent autoreactive immune cells that have survived the mechanisms of central tolerance from damaging the periphery.

Peripheral tolerance ppt

Autoimmune disease is believed to result from the bypass of at least one of the mechanisms of self–tolerance, and the mechanism differs from disease to disease. 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.

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.

Chapter 8 Immunological Tolerance.ppt 8 Peripheral T cell tolerance to self-antigen Despite the thymic surveillance, some of the autoaggressive self-reactive lymphocytes escape negative selection and circulate in the blood of healthy individuals.

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. Peripheral tolerance also induces T regulatory cell activity in those Tregs that recognize self-antigen, and this is followed by the Treg cells downregulating the activity of other immune cells that respond to that antigen.
