(Submitter supplied) The goals of this study are to comprehensively identify genes controlled by Jmjd6 in the thymic stroma, and to identify a novel alternative splicing mechanism. Methods: Samples were WT and Jmjd6-/- fetal thymus organ culture with (2 samples for each category) or without (1 sample for each category) RANKL stimulation for 4 days under 2-DG. One µg of total RNA was used for library construction with TruSeq RNA Sample Prep Kit v2. more...

(Submitter supplied) Aire in medullary thymic epithelial cells plays an essential role in the negative selection through expression of broad arrays of tissue-restricted antigens. We asked whether Aire could also activate the expression of tissue-restricted antigens in cortical thymic epithelial cells.

(Submitter supplied) Medullary thymic epithelial cells play essential role for induction of central self-tolerance. This functional capacity is mediated through a phenomenon known as promiscuous gene expression (pGE) of various tissue-restricted antigen (TRA) genes. pGE was previously shown to be mediated by a single factor called the Autoimmune regulator (Aire), which is specically expressed by mTECs. The aim of this study was to analyze the impact of deacetylase Sirtuin1, which is also highly expressed by mTECs, on mTEC gene expression profile and compare it with the impact of Aire. more...

(Submitter supplied) Autoimmune regulator (Aire) is a unique transcriptional regulator that induces promiscuous expression of thousands of tissue-restricted antigens (TRAs) in medullary thymic epithelial cells (mTECs), a step critical for induction of immunological self-tolerance. Although several recent studies provided very important molecular insights into how Aire operates, a more comprehensive understanding of this process still remains elusive. more...

(Submitter supplied) Mice used were B6/129 F2's, 3-5 weeks of age, either wild type or with both copies of the autoimmune regulator gene (aire, GenBank #AF079536) disrupted. Thymi from five of these mice of both sexes were removed and pooled. After collagenase/dispase digestion, density gradient fractionation, and fluorescent antibody staining, cells with the phenotype CD45-, G8.8+, CDR1int and B7.1hi were FACS-sorted and total RNA was made from them. more...

(Submitter supplied) Analysis of the role of Hipk2 in regulating gene expression in medullary thymic epithelial cells. The whole genome gene signatures of purified mTEC subsets (CD80 low, CD80 high) from TEC-specific Hipk2 knockout mice were compared to mating wildtype control mice (floxed, Cre-). Results provide the up- or down-regulated genes, affected by the Hipk2 gene knockout.

(Submitter supplied) Promiscuous gene expression (pGE) of numerous self-antigens in thymic epithelial cells (TEC) enables the elimination of self-reactive T cells. The autoimmune regulator (Aire) is the only known molecular determinant driving pGE in the thymus but the existence of Aire-independent mechanisms has been inferred. Here, we analyzed the poly(A)+ transcriptome of TEC populations by RNA-sequencing (RNA-seq) in order to reveal differential features of Aire-induced vs. more...

(Submitter supplied) Thymic central tolerance is essential to preventing autoimmunity. In medullary thymic epithelial cells (mTECs), the Autoimmune regulator (Aire) gene plays an essential role in this process by driving the expression of a diverse set of tissue-specific antigens (TSAs), which are presented and help tolerize self-reactive thymocytes. Interestingly, Aire has a highly tissue-restricted pattern of expression, with only mTECs and peripheral extrathymic Aire-expressing cells (eTACs) known to express detectable levels in adults. more...

(Submitter supplied) The deficiency of Aire, a transcriptional regulator whose defect results in the development of autoimmunity, is associated with reduced expression of tissue-restricted self-Ags (TRAs) in medullary thymic epithelial cells (mTECs). Although the mechanisms underlying Aire-dependent expression of TRAs need to be explored, the physical identification of the target(s) of Aire has been hampered by the low and promiscuous expression of TRAs. more...

(Submitter supplied) Gene expression in different thymic stromal cells and subsets thereof was analyzed in 6-12 week old wild type (C57BL/6) and Aire knock-out (mixed background) mice. Thymic stromal cells were purified by sequential enzymatic digestion (collagenase, collagenase/dispase and trypsin) followed by gradient centrifugation and FACS sorting. Sort criteria were as follows: dendritic cells (CD11c+, F4/80 -), macrophages (F4/80+, CD11c-), cTECs (CD45–/lo, CDR1/Ly51+, Ep-CAM+) and mTECs (CD45–/lo, CDR1/Ly51–, Ep-CAM+). more...

(Submitter supplied) Fezf2 is highly and specifically expressed in mTECs in mouse thymus and Fezf2 deficiency (Fezf2 KO) in the thymus leads to autoimmunity. However, it is unclear how Fezf2 contributes to thymic gene expression. We collected WT and Fezf2 KO mTECs by FACS, and performed microarrays to determine genes regulated by Fezf2.

(Submitter supplied) We show that thymic epithelial cells in the medulla (mTECs) that present self-antigens (self-Ags) to developing thymocytes for establishing immunological self-tolerance also express CTLA-4 if Aire, loss of which is responsible for the hereditary autoimmunity, is nonfunctional. Upon binding with its ligand, CD80 and CD86, expressed on thymic DCs, CTLA-4/ligand complex was internalized by Aire-deficient mTECs. more...
