process where immune system avoids attacking body's own cells

Immune tolerance is the process by which the immune system learns to recognize and not attack the body's own cells and tissues. This is crucial for preventing autoimmune diseases, where the immune system mistakenly targets the body's own cells, such as in alopecia areata where hair follicles are attacked. For professionals, it involves mechanisms like central tolerance in the thymus and peripheral tolerance in other tissues to maintain self-tolerance and prevent autoimmunity.
