Antibodies are proteins that the body manufactures. They also go by the name immunoglobulins. In essence, these antibodies are vital in the fight against antigens. An antigen is an invading microbe or pathogen. The immune system in the body regards antigens as threats. Consequently, the immune system produces antibodies against these antigens.
Antibodies actually go on the attack against these antigens. They attach themselves to antigens to deactivate them and their harmful behavior. These antigens can be fungi, viruses or bacteria. They are responsible for causing diseases, as well as infections. On top of that they can be allergens as well. Five classifications of antibodies exist. These are IgG, IgA, IgM, IgD, and IgE (Ig = immunoglobulin or antibody). Immunity is the ability to resist the effects of a certain disease.
The production of antibodies can occur when a person's immune system mistakes healthy tissue as a harmful material. The result of this is an Autoimmune Disorder. Over 80 autoimmune disorders are in existence. This type of disorder can cause the obliteration of one or more types of body tissue. It can also result in abnormal growth of an organ or cause changes in the function of an organ in the body.
