T-cell anergy and altered T-cell receptor signaling: effects on autoimmune disease

Abstract

Immunological self-tolerance can be acquired by several mechanisms, including the induction of anergy in autoreactive T cells. In this sense, anergy is predictably advantageous for the immune system. Here, Konstantin Salojin and colleagues present an alternative view that the induction of anergy in regulatory T cells may be harmful to the host and elicit autoimmune disease.
