(Submitter supplied) Thymic epithelial cells (TEC) effect crucial roles in thymopoiesis including the control of negative thymocyte selection. This process depends on their capacity to express promiscuously genes encoding tissue-restricted antigens. This competence is accomplished in medullary TEC (mTEC) in part by the presence of the transcriptional facilitator AutoImmune REgulator, AIRE. AIRE-regulated gene transcription is marked by repressive chromatin modifications, including H3K27me3. 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) Analysis of gene co-expression patterns in TRA-specific medullary thymic epithelial cell (mTEC) subsets. The whole genome gene signatures of purified mTEC subsets respectively positive for the TRAs Gp2, Pdpn, Cea1, Gad1, Ins2, Tspan8 were compared to their corresponding TRA-negative mTEC subset control. Results provide the enriched and depleted gene expressions in the different subsets.

(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) The aim of this study is to evaluate the effect of Autoimmune regulator (Aire) gene disruption in a murine medullary thymic epithelial cells (mTEC 3.10 cell line) on the transcriptome of these cells during its adhesion with thymocytes. The mTEC-thymocyte adhesion is a crucial step for the negative selection of autoreactive thymocytes and prevention of autoimmune diseases. To generate Aire mutant cell clones, a total of 5x10^5 mTEC 3.10 cells were electro-transfected (Lonza Nucleofector) with CRISPR-Cas9 plasmid targeting the Aire Exon 3 (plasmid "all in one" encoding Aire Exon 3 gRNA + Cas9 + GFP, from Sigma-Aldrich). more...

(Submitter supplied) Thymic epithelial cells (TEC) guide selection of a T-cell repertoire that is reactive to pathogens but tolerant to self. While this process is known to involve the promiscuous expression of virtually the entire protein-coding gene repertoire by TEC, the extent to which these cells reproduce peripheral isoform structures is unknown. We performed a transcriptomic investigation of transcript structures and splicing factor expression in medullary TEC and 21 peripheral tissues. more...

(Submitter supplied) Medullary thymic epithelial cells (mTECs) play a critical role in central immune tolerance by mediating negative selection of autoreactive T cells through the collective expression of the peripheral self-antigen compartment, including tissue-specific antigens (TSAs). Recent work has shown that gene expression patterns within the mTEC compartment are remarkably heterogenous and include multiple differentiated cell states. 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) 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...

(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...
