<unk>  is a term in immunobiology that describes a lack of reaction by the body's defense mechanisms to foreign substances, and consists of a direct induction of peripheral lymphocyte tolerance. An individual in a state of<unk>  often indicates that the immune system is unable to mount a normal immune response against a specific antigen, usually a self-antigen. Lymphocytes are said to be<unk> c when they fail to respond to their specific antigen.<unk>  is one of three processes that induce tolerance, modifying the immune system to prevent self-destruction (the others being<unk>  deletion and immunoregulation).
