Differentiation of naive CD4 T cells into Th2 cells is accompanied by chromatin remodeling and increased expression of a set of Th2-specific genes, including those encoding Th2 cytokines. IL-4-mediated STAT6 activation induces high levels of transcription of GATA3, a master regulator of Th2 cell differentiation, and enforced expression of GATA3 induces Th2(More)
Impairment of endothelial cells by oxidized low density lipoprotein (OxLDL) is believed to be the first step in atherogenesis. It is also believed that oxidative stress/antioxidant imbalance is involved in the cell damage by OxLDL. However, little is known about the interaction between OxLDL and antioxidants. In this study, we show that treatment of human(More)
Polycomb group (PcG) gene products regulate the maintenance of homeobox gene expression in Drosophila and vertebrates. In the immune system, PcG molecules control cell cycle progression of thymocytes, Th2 cell differentiation, and the generation of memory CD4 T cells. In this paper, we extended the study of PcG molecules to the regulation of in vivo Th2(More)
Functionally polarized CD4+ T helper (Th) cells such as Th1, Th2 and Th17 cells are central to the regulation of acquired immunity. However, the molecular mechanisms governing the maintenance of the polarized functions of Th cells remain unclear. GATA3, a master regulator of Th2 cell differentiation, initiates the expressions of Th2 cytokine genes and other(More)
Posttranslational modifications of histones are well-established epigenetic modifications that play an important role in gene expression and regulation. These modifications are partly mediated by the Trithorax group (TrxG) complex, which regulates the induction or maintenance of gene transcription. We investigated the role of Menin, a component of the TrxG(More)
