Quizplus · Accepted Answer

Antigens are substances that trigger an immune response in the body. Bacteria, viruses, toxins, and allergens are all examples of antigens because they can stimulate the production of antibodies and activate immune cells. Macrophages, on the other hand, are immune cells that engulf and digest foreign substances in the body, but they are not themselves considered to be antigens.
