There are two mechanisms of T cell tolerance. These are CENTRAL and PERIPHERAL tolerance. Central tolerance involves the deletion of self-reactive T cells in the thymus. Tolerance is induced as the T cells are being made.

Peripheral tolerance takes place

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 . 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).

T regulatory cells (Tregs) represent agents to mediate tolerance to allografts so that the use of immunosuppressive drugs is avoided. In this regard, we previously demonstrated that the adoptive transfer of allogeneic Tregs into IL-2Rβ −/− mice prevented autoimmunity and led to allograft tolerance. Here, we investigated the requirements and mechanisms that favor this long-lasting tolerance. Induction of tolerance in the gut relies on immunomodulatory functions of mesenteric lymph nodes (mLN).

Here, we investigated the requirements and mechanisms that favor this long-lasting tolerance. The recognition of what is "foreign" and what belongs to ones "own" body is a fundamental property of the immune system.The achieving of this self-tolerance occurs mainly during the T cell maturation in the thymus.Surprisingly, 95% of all the cells formed there die before they are ready to mature and emigrate into the peripheral lymphatic organs. This wastefulness is due to the extremely Cross-tolerance as a Consequence of Bone Marrow–derived APC Presentation of Peripheral Antigen. Although the experiments of Kurts et al. showed that CD8 + T cells were activated and proliferated in lymph nodes draining the sites of peripheral antigen expression (), this did not represent effective T cell priming.Long-term examination of the survival of these CD8 + T cells revealed their 2015-06-15 Peripheral tolerance is the second branch of immunological tolerance, after central tolerance.
