Quizplus · Accepted Answer

An antigen is a substance that triggers an immune response and stimulates the immune system to produce and release antibodies. Antibodies are proteins produced by the immune system in response to foreign substances like antigens. Interleukins are proteins that help regulate the immune system, and fibrinogen and prothrombin activator are involved in blood clotting, not the immune response.
