In vivo induction of anergy in peripheral
WebProbably the division of Th1 (Tc1) phenotype in ARF and a protective Th2 (Tc2) phenotype suggest a mechanism for induction of peripheral self tolerance/anergy in the T cell … WebAccumulating evidence suggests that PD-1, an immuno-inhibitory receptor expressed on activated T cells, regulates peripheral T cell tolerance. In particular, PD-1 is involved in the induction and/or maintenance of T cells’ intrinsic unresponsiveness

In contrast to robust immune reactions to infectious pathogens, tumor-infiltrating lymphocytes (TILs) and other tumor-resident immune cells can be functionally impaired and dysregulated, a condition termed “T cell exhaustion”, which can be exemplified by …
WebSep 1, 2006 · The role of the cell cycle in anergy induction The link between cell cycle arrest and anergy induction has been demonstrated both in vitro and in vivo [34], [35], [36], [37], [38], [39], [40]. In vitro, it has been shown that even in the presence of costimulation anergy can be induced if cell cycle arrest occurs in G1 [41]. WebInduction of Anergy. Anergy induction is another mechanism of lymphocyte tolerance, in which the lymphocyte is functionally unresponsive after antigen encounter but remains …
WebThrough the use of mice expressing transgenic T-cell receptors specific for foreign antigens, we have concluded that the separable mechanisms of anergy and active suppression by CD25 + T cells work in concert to produce peripheral tolerance.
