immunotolerance is a state of the insensitivity of the immune system to substances or tissue that have the capacity to provoke an immune response in a specified organism. It is brought by prior exposure to that specific antigen then contrasts with the predictable immune-mediated elimination of foreign antigens. Tolerance is classified into central tolerance or peripheral tolerance depending on where the state is originally persuaded—in the thymus and bone marrow(central) or in other tissues and lymph nodes (peripheral). The mechanisms by which these forms of tolerance are established are distinct, but the subsequent effect is parallel.
- Track 1-1 Central tolerance
- Track 2-2 Peripheral tolerance
- Track 3-3 Allograft tolerance
- Track 4-4 Oral tolerance and hypersensitivity
- Track 5-5 mucosal immune tolerance
- Track 6-6 Maternal immune tolerance
