Peripheral tolerance develops after T and B cells mature and enter the peripheral tissues and lymph nodes. It is established by a number of partly overlapping mechanisms that mostly involve control at the level of T cells, especially CD4+ helper T cells, which orchestrate immune responses and give B cells the confirmatory signals they need in order to produce antibodies. 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).

Peripheral tolerance takes place

B cells are made tolerant whilst maturing in the bone marrow. 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.

Here, we investigated the requirements and mechanisms that favor this long-lasting tolerance.

1, 2 The mechanisms of positive and negative selection in the thymus are key to the shaping of a self‐tolerant T‐cell repertoire, especially in early life during the maturation of the … This capacity of DCs to induce peripheral tolerance can work in two opposing ways in the context of infection. In acute infection, a beneficial effect should occur.

Here the authors show that mLN stromal cells receive early microbiota imprinting in the 4 hours ago 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.

This will impose a peripheral T cell repertoire composed of many small T cell clones, i.e., guaranteeing repertoire diversity.
