An antigen is any substance that the immune system can recognize thus stimulates an immune response. If antigens are considered dangerous (for example, if they can cause disease), they can stimulate an immune response in the body.

What stimulates an immune response?

Antigens and Antibodies

An antigen is a molecule that stimulates an immune response to which an antibody binds – in fact, the name comes from « antibody generator ». Any given organism contains several different antigens.

What is the role of antigens in the immune response?

Antigens are substances (usually proteins) on the surface of cells, viruses, fungi or bacteria. Inanimate substances such as toxins, chemicals, drugs, and foreign particles (eg, debris) can also be antigens.immune system Recognize and destroy or attempt to destroy substances containing antigens.

In the antibody reaction, B cells are activated to secrete antibodies, which are proteins called immunoglobulins. Antibodies circulate in the bloodstream and penetrate into other body fluids, where they bind specifically to the foreign antigen that stimulates their production (Figure 24-2).
