The definition of antigen is a harmful substance which enters the body which causes the body to make antibodies as a response to fight off disease. An example of an antigen is a common cold virus which causes the body to make antibodies which help prevent the person from getting sick.
In immunology, an antigen is a molecule capable of inducing an immune response (to produce an antibody) in the host organism. Sometimes antigens are part of the host itself in an autoimmune disease. Antigens are targeted by antibodies. Each antibody (immune response) is specifically produced by the immune system to match an antigen after cells in the immune system come into contact with it; this allows a precise identification/matching of the antigen and the initiation of a tailored response.
