Interleukin-12 as a Therapeutic Target of Th1-mediated Autoimmune Diseases

In the past it was thought that autoimmunity is mediated by antibodies and immune complexes. It has now become clear that many diseases, especially tissue specific, are T cell mediated or at least T cell dependent. The pathogenesis of cell-mediated autoimmune diseases, such as multiple sclerosis, uveitis, diabetes, arthritis, and others, is thought to be in a large measure driven by interferon-gamma-producing antigen-specific T cells polarized toward the Th1 phenotype.
