Anergy — A state of immune unresponsiveness. Induced when the T cell s antigen receptor is stimulated, effectively freezing T cell responses pending a second signal from the antigen presenting cell. The delivery of the second signal by the antigen… … Medical dictionary

Molecular mimicry — is defined as the theoretical possibility that sequence similarities between foreign and self peptides are sufficient to result in the cross activation of autoreactive T or B cells by pathogen derived peptides. Despite the promiscuity of several… … Wikipedia
T cell — T cells belong to a group of white blood cells known as lymphocytes, and play a central role in cell mediated immunity. They can be distinguished from other lymphocyte types, such as B cells and natural killer cells by the presence of a special… … Wikipedia
Central tolerance — is the mechanism by which newly developing T cells and B cells are rendered non reactive to self[1]. The concept of central tolerance was proposed in 1959 by Joshua Lederberg[2], as part of his general theory of immunity and tolerance, and is… … Wikipedia
Immune tolerance — or immunological tolerance is the process by which the immune system does not attack an antigen.[1] It can be either natural or self tolerance , in which the body does not mount an immune response to self antigens, or induced tolerance , in which … Wikipedia
