T cell anergy is one of the important mechanisms for immune tolerance. The results of many studies investigating the mechanism for T cell anergy induction have revealed that the expression of several genes was up-regulated in anergic T cells. It has also been demonstrated that the molecules encoded on those genes played a critical role in anergy induction. However, the mechanism for their up-regulation has not previously been clarified. We examined in this study the changes in gene expression and DNA methylation status caused by anergy induction. Our results demonstrate that the expression of many genes was changed by anergy induction, and that the DNA methylation status of some of these genes was also changed. We show here by a GO analysis that the extent of the change in methylation status caused by anergy induction was distinct between the groups of genes that were categorized.
