ABSTRACT
It has been estimated that autoimmune diseases (AIDs) affect 5-8% of the US population. AIDs are a serious public
health problem worldwide. These diseases are chronic conditions initiated by the loss of immunological tolerance to
self-antigens. AIDs cause various clinical consequences ranging from mild to severe, affecting one or more target organs
and repeatedly causing the patient’s death. Five of the most common AIDs are rheumatoid arthritis (RA), systemic lupus
erythematosus (SLE), Graves´ disease (GD), insulin-dependent diabetes mellitus or type I (T1DM), and multiple sclerosis
(MS). The TNF-α gene and its protein product, the cytokine TNF-α, play an important role in the pathogenesis of EAs.
The anti-TNF-α therapies using monoclonal antibodies directed against TNF-α have shown good results in diseases
such as RA, JRA, but not in other EA such as SLE and MS. This review focuses on presenting to the reader the
biological role of TNF-α under normal conditions and the initiation, development, susceptibility, severity, and treatment
response of the most common AIDs.
