An antigen is a substance or molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the â¦ antigen that is recognized as a foreign and potentially harmful invader.
Antigens are the little invaders that enter the body and trigger the immune system. They come in all different shapes and sizes. Antigens are mainly microbes such as bacteria, parasites, and fungi. They can also come from the environment, such as viruses, chemicals, pollen, and more. Each antigen may cause infection to the body. There are some antigens that seem harmless but still cause the immune system to respond, like pollen for example.
