An antibody, produced by B cells in response to an altered” self” antigen on one type of the body’s own cells, that attacks and destroys these cells. Autoantibodies are the basis for autoimmune diseases such as rheumatoid arthritis and diabetes mellitus. Several theories exist as to why autoantibodies are formed. The most commonly accepted theory proposes that AAbs develop as the result of a combination of hereditary and environmental risk factors that cause a “self’ antigen to be seen as foreign by B cells; as a result, antibodies are produced for its destruction.
An antibody, which is a protein produced by the immune system, is capable of targeting and reacting against the body’s own cells.
