Insm1 regulates the expression of thymic tissue-restricted antigens and the immune tolerance [CUT&Tag]

Project description:Insm1, encoding a zinc finger protein, is expressed specifically in neuroendocrine cells. Recent study showed the first evidence of Insm1 expression in medullary thymic epithelial cells (mTEC). Here we investigated the expression and function of Insm1 in mTEC. Mutation of Insm1 resulted in decreased proportion of mTEChi although normal development of other types of thymic cells. We detected altered expression of a subset of tissue-restricted antigens (TRAs) and mild decreased expression of Aire and Fezf2 in Insm1 mutant mTEC. We further showed that Insm1 recognizes a DNA sequence which is similar to the CCCTC-Binding factor (CTCF) binding motif. Mutation of Insm1 altered CTCF binding genome widely and thus the expression of genes. In nude mice transplanted with Insm1 mutant thymus, autoimmune responses were observed in multiple peripheral tissues. In thymus specific Insm1 mutant mice, we detected decreased induction of regulatory T (Treg) cells in the thymus, obvious lymphocytes infiltration and autoimmune antibody reaction in several peripheral tissues. In thymic epithelial cells specific Insm1 overexpression mice, we detected enlarged mTEC proportion and increased expression of mTEC specific genes. Thus, we suggest that Insm1 is a novel regulator of mTEC function and autoimmunity.

LC-MSMS of the MHC-I immunopeptidome of murine thymic epithelial cells

Project description:Antigen presentation by cortical and medullary thymic epithelial cells (cTEC and mTEC) ensures the formation of a self-restricted and self-tolerant T cell repertoire, respectively. As such, a broad diversity of self-antigens needs to be presented by mTEC to induce T cell’s self-tolerance. Even though the expression and antigen presentation of protein coding genes in mTEC has been abundantly described, little is known of the implication of allegedly noncoding regions of the genome to tolerance induction. In this study, we focused on transposable elements (TE), which have been shown to be highly expressed by mTEC.

Expression data from cortical thymic epithelial cells ectopically expressing Aire

Project description: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.

Aire regulates transfer of antigen from mTEC to dendritic cells for induction of thymic tolerance

Project description:To investigate the role of Aire in thymic selection, we examined the cellular requirements for generation of ovalbumin (OVA)-specific CD4 and CD8 T cells in mice expressing OVA under the control of the rat insulin promoter (RIP). Aire-deficiency reduced the number of mature single positive (SP) OVA-specific CD4+ or CD8+ T cells in the thymus, independent of OVA expression. Importantly, it also contributed in two way to OVA-dependent negative selection depending on the T cell type. Aire-dependent negative selection of OVA-specific CD8 T cells correlated with Aire-regulated expression of OVA. By contrast, for OVA-specific CD4 T cells, Aire affected tolerance induction by a mechanism that operated independent of the level of OVA expression, controlling access of antigen presenting cells to mTEC-expressed OVA. This study supports the view that one mechanism by which Aire controls thymic negative selection is by regulating the indirect presentation of mTEC-derived antigens by thymic dendritic cells. It also indicates that mTEC can mediate tolerance by direct presentation of Aireregulated antigens to both CD4 and CD8 T cells. Total RNA was extracted from medullary thymic epithelial cells isolated from wildtype and Aire-deficient C57BL/6 mice for comparison of gene expression profiles.
