Abstract:

The primary purpose of the immune system is to protect the body against a plethora of microorganisms, which are readily recognized as foreign under normal circumstances. However, the immune system must also be able to distinguish the protein fragments of these microorganisms from those of its own self-antigens through mechanisms of immune tolerance. In addition to genetic susceptibility, crossing this precarious line between responses to foreign versus self antigens may lead to autoimmunity.
