There is an antagonistic dynamic process between immune responses and immune tolerance after platelet-targeted gene therapy in a primed model. A peripheral B cell tolerance checkpoint further counterselects autoreactive new emigrant B cells before they enter the mature naive B cell compartment . Both central and peripheral B cell tolerance checkpoints are defective in untreated patients with active rheumatoid arthritis (RA) or type 1 diabetes (T1D) ( 5 , 6 ). Central tolerance is not perfect, so peripheral tolerance exists as a secondary mechanism to ensure that T and B cells are not self-reactive once they leave primary lymphoid organs. Peripheral tolerance is distinct from central tolerance in that it occurs once developing immune cells exit primary lymphoid organs (the thymus and bone-marrow), prior to their export into the periphery. TY - JOUR. T1 - Mechanisms of peripheral T cell 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 Mechanisms of immune tolerance: Peripheral T cell tolerance (IV): Suppression by Treg Neonate thymectomy --> Autoimmune diseases 1. The disease is transferable by T cells.

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 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. Mechanisms of immune tolerance: Peripheral T cell tolerance (IV): Suppression by Treg Conclusions: Tolerance vs. Immunity • Immune responses are the outcome of a balance between the need to make a protective response and the need to maintain self-tolerance • Mechanisms of unresponsiveness: – Central tolerance: Deletion; Receptor editing The PowerPoint PPT presentation: "Mechanisms of unresponsiveness: Peripheral tolerance in B cells (II): Anergy" is the property of its rightful owner.
