The importance of peripheral tolerance is listed as: 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). B-Cell Tolerance. B cell tolerance involves deletion or receptor editing in newly generated B cell clones that emerge in the bone marrow, when these clones reach the differentiation stage of immature B cells.

Seif† *Department of Microbiology and Immunology, Faculty of Pharmacy, and †Department of Surgery, Kasr-El-Aini Medical School, Cairo University, Cairo, Egypt Key Words: antigen presentation deletion suppression anergy INTRODUCTION 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.

It is here that their antigen  The immune system normally avoids producing antibodies that react with autologous ("self") antigens by censoring self-reactive T and B cells. Unlike the T cell  Peripheral B cell tolerance occurs at the level of peripheral (secondary) lymphoid tissues. Mature B cells recognizing self-antigens in the absence of T-cells  Central tolerance prevents the maturation and egress of autoreactive immune cells, for example via clonal deletion of T cells in the thymus1.

This defect in peripheral B cell tolerance is linked to fewer regulatory T cells that did not include common TCRβ clones found instead in the conventional T cell compartment. This T cell defect may not prevent the selection and expansion of autoreactive B cells to peripheral self-antigens, thus leading to autoantibody production.
