Project description:We compared gene expression profiles of lymphotoxin alpha- and lymphtoxin beta receptor-deficient thymic medullary epithelial cells with their wild-type littermates, as well as with Aire-deficient and wild-type littermates. This was done in order to determine whether there was overlap in the effects of lymphotoxin and aire. Keywords: genetic modification

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:We explored the role of the autoimmune regulator (Aire) gene in supporting fetal tolerance during pregnancy with transgenic diphtheria toxin receptor (Aire-DTR) mice, in which Aire-expressing populations can be deleted by injection of diptheria toxins (DT). Aire-expressing cell depletion was found to cause intruterine growth restriction (IUGR) in both allogenic and syngeneic pregnancies. This phenotype is immune-mediated, as IUGR is rescued in Rag1-deficient mice, and involves a memory response, as demonstrated by severe IUGR in second pregnancies. We further explored this phenotype through single-cell RNA sequencing of leukocytes obtained from the secondary lymphoid organs (uterine and non-uterine-draining lymph nodes) of wild-type (WT) and Aire-DTR pregnant dams during allogeneic pregnancy. Transciptomic data reveals a shift in population distributions from naïve to effector CD4+ and CD8+ T cells in Aire-DTR mice. Within the effector CD4+ compartment, there was a significant shift away from Tregs and toward mature T effectors, most notably T follicular helper (Tfh) and Th17 cells. These findings support the idea that Aire is essential in maintaining immune homeostasis.

Project description:Aire is an important transcription regulator that mediates a role in central tolerance via promoting the promiscuous expression of tissue-specific antigens in the thymus. Although several mouse models of Aire-deficiency have been described, none has analysed the phenotype induced by a mutation that emulates the common 13bp deletion in human APECED by disrupting the first PHD domain in exon 8. Aire-deficient mice with a corresponding mutation showed some disturbance of the medullary epithelial compartment, but at the phenotypic level their T cell compartment appeared relatively normal in the thymus and periphery. An increase in the number of activated T cells was evident, and autoantibodies against several organs were detected. At the histological level, lymphocytic infiltration of several organs indicated the development of autoimmunity, though symptoms were mild and quality of life for Aire-deficient mice appeared equivalent to wild-type littermates, with the exception of male infertility. Vbeta and CDR3 length analysis suggested that each Aire-deficient mouse developed it own polyclonal autoimmune repertoire. Finally, given the prevalence of candidiasis in APECED patients, we examined the control of infection with Candida albicans in Aire-deficient mice. No increase in disease susceptibility was found for either oral or systematic infection. These observations support the view that additional genetic and/or environmental factors contribute substantially to the overt nature of autoimmunity associated with Aire mutations, even for mutations identical to those found in humans with APECED. Keywords: Gene expression comparison between genotypes In this experiment there are 5 samples altogether which consist of two biological replicates of Aire knock-out mTECs and 3 biological replicates of wild type mTECs.

Project description:We compared gene expression profiles of lymphotoxin alpha- and lymphtoxin beta receptor-deficient thymic medullary epithelial cells with their wild-type littermates, as well as with Aire-deficient and wild-type littermates. This was done in order to determine whether there was overlap in the effects of lymphotoxin and aire. Experiment Overall Design: Individual thymi were digested with collagenase, dispase and DNAse, and meduallary epithelial cells with the phenotype CD45-G8.8+Ly51intMHCclasssIIhi were isolated by FACS.

Project description: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. –independent pGE. We report an unanticipated effect of Aire deletion on the proliferation and differentiation of cortical TEC. Moreover, the RNA-seq data reveal the breath of Aire-induced and –independent pGE in medullary TEC (mTEC) subsets and the extent of thymic peripheral tissue representation. The results suggest that Aire-induced promiscuously expressed transcripts affect several functions with far reaching biological consequences in mTEC. High-throughput characterization of TEC transcriptomes will enable progress in understanding TEC biology and the establishment of self-tolerance. The mRNA profiles of cTEC, mTEClo and mTEChi from 6-8 week-old wild type (WT) and Aire-/- (KO) mice were generated by RNA-sequencing using Illumina HiSeq2000.
