However, in the present studies we did not find evidence for physical disappearance (deletion) of peripheral T cells as was described by others (10, 16, 17). But it is possible that some peripheral deletion also takes place and contributes to the peripheral tolerance in the mice described here.

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 ). Its main purpose is to ensure that self-reactive T and B cells which escaped central tolerance do not cause autoimmune disease .

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 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 ). Its main purpose is to ensure that self-reactive T and B cells which escaped central tolerance do not cause autoimmune disease . Peripheral tolerance: The occurrence of peripheral tolerance takes place when the mature lymphocytes that recognize self-antigens loses its The importance of peripheral tolerance is listed as: To maintain unresponsiveness to self-antigens that are expressed in To maintain unresponsiveness to 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).

Mechanisms of central and peripheral T cell tolerance to an antigen of the central nervous system. Myelin reactive T cells are central in the development of the autoimmune response leading to central nervous system (CNS) destruction in Multiple Sclerosis (MS) and its animal model, Experimental Autoimmune Encephalomyelitis (EAE). • central tolerance to tissue-restricted antigens – induction of central tolerance in B cells • Peripheral tolerance – „recessive“ tolerance – „dominant“ tolerance • identification of cell populations with suppressive („regulatory“) features • most prominent example: CD4+/CD25+ natural 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 ).

It takes place in the immune periphery (after T and B cells egress from primary lymphoid organs). Peripheral mechanisms of tolerance eliminate or suppress autoreactive clones that escape to the periphery Mechanisms of peripehral T-cell tolerance include: A. Clonal deletion B. Ignorance C. Anergy D. Immune regulation Tolerance mechanisms can also result in inappropriate tolerance to non-self antigens. Why is it called peripheral tolerance?
