The fail-safe paradigm of immunological self-tolerance

Abstract:
Immunological self-tolerance is guaranteed by several complementary mechanisms arranged in a fail-safe hierarchy--namely, clonal deletion, inactivation, and suppression. Only failure of all these self-tolerance-preserving systems allows autoimmune disease to develop. The notion of such a fail-safe organisation of the immune system is compatible with several features of autoimmune disease: its multicausal nature, its slowly progressive and relapsing course, and the diverse range of interventions available to restore autotolerance. This hypothesis has practical implications for the understanding of both the pathogenesis of iatrogenic autoimmune disease and the design of strategies to re-establish self-tolerance.

What is the Immune System?
Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
