Project description: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. mTECs were subjected to RNA extraction (from WT or Fezf2 KO mTECs) and hybridization on Affymetrix microarrays.

Project description:To integrate the epigenomic landscapes of chromatin accessibility regulated by Chd4 and Fezf2, we performed the assay for transposase-accessible chromatin using sequencing (ATAC-seq) analysis of mTECs from wild type (WT), Chd4 cKO and Fezf2 cKO mTECs.

Project description:To investigate the genome-wide binding pattern of Fezf2, we performed ChIP-seq analysis for Fezf2. ChIP-seq of transcription factor in mTECs is difficult because of small number of mTECs or difficulty in gaining ChIP grade antibodies. Then, we generated Fezf2-3Flag knock in mice and performed ChIP-seq analysis by using anti-Flag antibody.

Project description:ChIP sequencing of Ehf, Fezf2, Elf3 and Klf4 was performed on medullary thymic epithelial cells to analyze the role of Ehf-, Fezf2-, Elf3- and Klf4-dependent gene regulation in mTECs.

Project description:To gain insights into the difference in transcriptional programs regulated by Fezf2, Aire and Chd4, we performed RNA sequencing (RNA-seq) of mTECs from Fezf2-deficient, Aire-deficient and Chd4-deficient mice.

Project description:Medullary thymic epithelial cells (mTECs) are essential for the establishment of self-tolerance in T cells. Promiscuous gene expression by a subpopulation of mTECs regulated by nuclear protein Aire contributes to the display of self-genomic products to newly generated T cells. Recent reports have highlighted additional self-antigen-displaying mTEC subpopulations; namely, Fezf2-expressing mTECs and a mosaic of self-mimetic mTECs including thymic tuft cells. In addition, a functionally different subset of mTECs produces chemokine CCL21 that attracts developing thymocytes to the medullary region. Here we report that CCL21+ mTECs and Aire+ mTECs non-redundantly cooperate to direct self-tolerance to prevent autoimmune pathology by optimizing the deletion of self-reactive T cells and the generation of regulatory T cells. We also detected a cooperation for self-tolerance between Aire and Fezf2, which unexpectedly regulates thymic tuft cells. Our results indicate an indispensable interplay among functionally diverse mTECs for the establishment of central self-tolerance.
