Analysis of sirtuin 1 expression reveals a molecular explanation of IL-2–mediated reversal of T-cell tolerance

Abstract excerpt

The type III histone deacetylase sirtuin 1 (Sirt1) is a suppressor of both innate and adoptive immune responses. We have recently found that Sirt1 expression is highly induced in anergic T cells. However, the transcriptional program to regulate Sirt1 expression in T cells remains uncharacterized. Here we report that the early responsive genes 2 and 3, which can be up-regulated by T-cell receptor-mediated...
