When the body’s immune system recognizes dangerous molecules called antigens, it produces an antibody. Microorganisms (bacteria, fungi, parasites, and viruses) and chemicals are examples of antigens.

Antibodies are created when the immune system incorrectly interprets healthy tissue as a threat is referred to as an autoimmune disease.

Antibodies are one-of-a-kind proteins that defend the body from a certain type of antigen.
