The necessity for self-recognition was appreciated in 1900, but autoimmune disease did not become a clinical reality until the 1950s-still the perimeters are indistinct.
Autoimmune responses recapitulate the complex events of normal immune responses but cannot shut down.
Immune tolerance is established during repertoire development centrally in thymus or bone marrow by deletion of self-reactive immunocytes, and is supplemented peripherally by regulatory T cells (TREGs).
