Alloantibodies

Alloantibodies are specialized proteins produced by the immune system in response to foreign antigens from another person of the same species. These antibodies target specific proteins on the surface of cells, such as blood cells or tissue transplants, which the body recognizes as foreign. For example, in blood transfusions or organ transplants, alloantibodies can cause immune reactions that may lead to rejection or complications. Understanding alloantibodies is important for ensuring compatibility and reducing the risk of immune responses in medical procedures like transfusions and transplants.
