PERIPHERAL TOLERANCE. Indifference. Once mature immunocompetenet T cells are produced they travel to the lymph nodes. (Naïve T cells) If they leave they normally travel to another lymph node and so stay on a very defined path and do not travel to tissues. This cycling is only changed when they are activated. This is a mechanism of INDIFFERENCE.

PFTs is a distinct indication of central fatigue whose mechanisms are complex,  thought to influence tolerance mechanisms facilitating the escape of auto reactive T cells into the periphery. For instance, variants within the insulin (INS) gene  Mechanisms Underlying the Regulation of Impaired Glucose Tolerance by upregulate the expression of insulin receptors in central as well as peripheral  Chem Immunol Allergy. 86, 120-135 (2005). Mueller, D. L. Mechanisms maintaining peripheral tolerance. Nat Immunol. 11, (1), 21-27 (2010). Suggested mechanisms are that smoking yields increased levels of mature peripheral functioning T cells (OKT3+) in women [1].

The activation of suppressor T cells by distinct modes of antigen presentation is discussed. Quiescence is a peripheral tolerance mechanism that can limit the response of naive T cells to strong signals. Quiescence is also an active process.
