transplant tolerance

Transplant tolerance refers to a medical condition where a person’s immune system accepts a transplanted organ or tissue as its own, rather than attacking it. Typically, the immune system recognizes foreign cells and mounts a defense, which can lead to rejection of the transplant. However, with tolerance, the body learns to coexist with the new cells, preventing rejection without the need for lifelong immunosuppressive drugs. Achieving transplant tolerance is a significant goal in transplantation medicine, as it can improve the quality of life for transplant recipients and reduce the risk of complications.
