Immune rejection occurs when the immune system identifies a transplanted organ or tissue as foreign and mounts an immune response against it, potentially leading to the failure of the transplant. This process involves complex interactions between donor and recipient immune cells, and managing it often requires immunosuppressive therapies to prevent rejection and maintain transplant viability.

The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens and maintain overall health. It involves both innate and adaptive responses, which recognize and neutralize foreign invaders while also retaining memory for faster future responses.

The immune response is the body's defense mechanism against pathogens, involving a complex interplay between innate and adaptive immunity. It includes the recognition of foreign antigens, activation of immune cells, and the elimination of pathogens, while also maintaining tolerance to self-antigens to prevent autoimmunity.

Complex interactions refer to the intricate and often unpredictable ways in which different elements or systems influence each other, leading to outcomes that cannot be easily deduced from the properties of the individual components alone. These interactions are fundamental in understanding phenomena in fields ranging from ecology to economics, where the behavior of the whole system is more than just the sum of its parts.
