Mechanisms Underlying the Regulation of Impaired Glucose Tolerance by upregulate the expression of insulin receptors in central as well as peripheral 

Fortunately, additional tolerance mechanisms exist that restrain the numbers and or function of T cells that are reactive to developmental or food antigens, which are not thymically expressed. These mechanisms act on mature circulating T cells and are referred to as “peripheral tolerance.”

For this reason, peripheral tolerance has developed in peripheral lymphoid organs regulated by intrinsic and extrinsic T‐cell mechanisms. Abstract. Our studies on the immune response to foreign antigens are reviewed as they relate to the mechanisms of peripheral immune tolerance. 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.

Peripheral tolerance involves a set of mechanisms which ensures that autoreactive T-lymphocytes are not activated in the periphery. It should be noted that 

immune tolerance: self vs. non-self; central and peripheral tolerance 2. autoimmunity: genetic susceptibility and activation through  17 Oct 2006 One such mechanism has been called adaptive tolerance [4]. The exposure of naïve helper T cells to chronic peripheral antigenic stimulation  The mechanism, in peripheral lymphoid organs (LYMPH NODES; SPLEEN; TONSILS; and mucosal-associated lymphoid tissue), that prevents mature  av E Lindmark · 2013 — Autoimmune diseases such as diabetes mellitus and multiple sclerosis are increasing today, but the mechanism behind these diseases remains largely unknown.

Peripheral mechanisms of tolerance eliminate or suppress autoreactive clones that escape to the periphery Mechanisms of peripehral T-cell tolerance include: A. Clonal deletion B. Ignorance C. Anergy D. Immune regulation Tolerance mechanisms can also result in inappropriate tolerance to non-self antigens.

Y1 - 1999. N2 - The mechanisms of induction and maintenance of tolerance in self-reactive T cells in the periphery are poorly understood. Peripheral tolerance is the second branch of immunological tolerance, after central tolerance. It takes place in the immune periphery (after T and B cells egress from primary lymphoid organs ). Its main purpose is to ensure that self-reactive T and B cells which escaped central tolerance do not cause autoimmune disease .

AU - van Parijs, L. AU - Perez, V. L. AU - Abbas, A. K. PY - 1998. Y1 - 1998. N2 - Peripheral tolerance to self proteins is induced because these antigens are presented to T lymphocytes under conditions that do not allow effective immune responses to develop, or because the responses of the specific T cells are tightly regulated. Foxp3-independent mechanism by which TGF-β controls peripheral T cell tolerance Soyoung A. Oha, Ming Liua, Briana G. Nixona, Davina Kanga, Ahmed Tourea, Michael Bivonaa, and Ming O.

However, whether TGF-β and Treg cells are part of the same regulatory module, or exist largely as distinct pathways to repress self-reactive T cells remains incompletely understood. Using a tran … The agg Ig-peptide approach brings together a peripheral tolerance-like mechanism and the antagonism activity of IL-10 to strengthen the modulatory functions against aggressive T cells. Furthermore, as IL-10 exerts its downregulatory function in a paracrine fashion, it may counteract neighboring Th1 cells regardless of antigen specificity.

Central tolerance is imposed during the development of T cells in the thymus, while peripheral tolerance occurs after T cells are exported into the periphery.

Fortunately, additional tolerance mechanisms exist that restrain the numbers and or function of T cells that are reactive to developmental or food antigens, which are not thymically expressed. These mechanisms act on mature circulating T cells and are referred to as “peripheral tolerance.”
