Alloimmune Response

The alloimmune response occurs when the immune system reacts against foreign tissues from another individual of the same species, often seen in organ transplants or blood transfusions. This happens because the recipient's body recognizes the donor's cells as "non-self" and mounts an immune attack. The immune system produces antibodies and activates immune cells to reject the foreign tissue. Managing this response is crucial in medical procedures to ensure successful transplants and avoid complications like transplant rejection. Therapies like immunosuppressants are used to help prevent the alloimmune response in these situations.
