Question

Quizplus · Accepted Answer

Tissue rejection following organ transplantation occurs when the immune system of the recipient recognizes the transplanted tissue as foreign and mounts an immune response against it. This immune response is often triggered by the presence of MHC incompatibility between the donor and recipient, and involves the activation of both T and B cells. T cells recognize and attack the foreign tissue directly, while B cells produce antibodies that bind to the foreign tissue and mark it for destruction by other immune cells. However, tissue rejection does not occur when tissues are transplanted from one part of the body to another in the same person, as the immune system recognizes these tissues as "self" and does not mount an immune response against them.
