Zfp281 and Zfp148 control CD4+ T cell thymic development and Th2 functions. (ChIP-seq)

ABSTRACT: How CD4+-lineage gene expression is initiated in differentiating thymocytes remains poorly understood. Here, we show that the paralog transcription factors Zfp281 and Zfp148 control both this process and cytokine expression by Th2 effector cells. Genetic, single-cell, and spatial transcriptomic analyses show that these factors promote the intrathymic CD4+ T cell differentiation of MHC II-restricted thymocytes, including expression of the CD4+ lineage-committing factor Thpok. In peripheral T cells, Zfp281 and Zfp148 promote chromatin opening at and expression of Th2 cytokine genes, but not of the Th2 lineage determining transcription factor Gata3. Zfp281 interacts with Gata3, and binds Gata3 genomic binding sites at loci encoding Thpok and Th2 cytokines. Thus, Zfp148 and Zfp281 collaborate with Gata3 to promote CD4+ T cell development and Th2 cell responses.

Zfp281 and Zfp148 control CD4+ T cell thymic development and Th2 functions

Project description:How CD4+ lineage gene expression is initiated in differentiating thymocytes remains poorly understood. Here, we show that the paralog transcription factors Zfp281 and Zfp148 control both this process and cytokine expression by T helper cell type 2 (TH2) effector cells. Genetic, single-cell, and spatial transcriptomic analyses showed that these factors promote the intrathymic CD4+ T cell differentiation of class II major histocompatibility complex (MHC II)–restricted thymocytes, including expression of the CD4+ lineage–committing factor Thpok. In peripheral T cells, Zfp281 and Zfp148 promoted chromatin opening at and expression of TH2 cytokine genes but not of the TH2 lineage–determining transcription factor Gata3. We found that Zfp281 interacts with Gata3 and is recruited to Gata3 genomic binding sites at loci encoding Thpok and TH2 cytokines. Thus, Zfp148 and Zfp281 collaborate with Gata3 to promote CD4+ T cell development and TH2 cell responses. This SuperSeries is composed of the SubSeries listed below.

The transcription factor Zfp281 serves redundantly with Zfp148 to support CD4+ T cell development and functions [Thymus Visium]

Project description:The transcription factor Gata3 is essential both for CD4+ T cell development in the thymus and for the differentiation of Th2 cells, which mediate responses against extracellular parasites and contribute to asthma and allergies. Here we report that the transcription factor Zfp281, in part redundantly with its paralog Zfp148, cooperates with Gata3 to promote CD4+ T cell development and Th2 cell differentiation. Disruption of both factors in T cells resulted in reduced numbers of spleen CD4+ T cells. Additionally, we show that Zfp281 interacts with Gata3, and that Zfp281 binds to Th2 cytokine loci in Th2 cells. Finally, we found that Zfp148 and Zfp281 promote Th2 cytokine expression. During airway inflammation, Zfp148/281-deficient CD4+ T cells failed to express Th2 cytokines, despite normal expression of Gata3. Altogether our data identify Zfp148 and Zfp281 as essential for enabling Gata3 functions in both CD4+ T cell development and Th2 function.

ChIP-seq data for zfp148 and zfp281 chromatin occupancy in hemin-induced human K562 cells

Project description:ChIP-seq was carried for zfp148 and zfp281 in human K562 cells to test the hypothesis that these two transcription factor family members play overlapping roles in erythropoiesis.

Transcriptional changes in intraepithelial CD4 lymphocytes

Project description:We investigated transcriptional changes in CD4CD8aa and CD4 intraepthelial lymphocytes. TCRÎ±Î² thymocytes differentiate to either CD8Î±Î² cytotoxic T lymphocytes or CD4 T helper cells. This functional dichotomy is controlled by key transcription factors, including the T helper master regulator, ThPOK, which suppresses the cytolytic-program in MHC class II restricted CD4 thymocytes. ThPOK continues to repress CD8-lineage genes in mature CD4 T cells, even as they differentiate to T helper effector subsets. Surprisingly, we show here that the T helper-fate is not fixed and that mature antigen-stimulated CD4 T cells can switch off Thpok expression and reactivate CD8-lineage genes. This unexpected plasticity results in the post-thymic termination of the T helper program and the functional differentiation of distinct MHC class II restricted CD4 cytotoxic T lymphocytes. Intraepithelial_CD4_CD8a neg vs CD8a pos. Two sample set of CD4CD8aa and CD4 intraepthelial lymphocytes (IEL) from small intestine of RAG knockout mice ( 8 weeks after transfer of naive CD4 cells, adoptive tranfer model of colitis), were prepared via cell sorting, and RNA was prepared by TRIZol (Invitrogen, USA) . Data were analyzed in GeneSpring GX10. For microarray analysis, RNA was labeled and hybridized to GeneChip Mouse Genome 430 2.0 arrays according to the Affymetrix protocols. Data were analyzed in GeneSpring GX10.

Transcriptional changes in intraepithelial CD4 lymphocytes

Genome-wide maps of SATB1 bound regions in thymocytes and peripheral CD4+ T lymphocytes.

Project description:T-cell receptor (TCR) signaling by MHC class-I and -II induces thymocytes to acquire cytotoxic and helper fates via induction of Runx3 or and ThPOK transcription factors, respectively. The mechanisms by The mechanisms by which TCR signaling is translated into transcriptional programs for each cell fate remain elusive. It remains elusivewhich how TCR signaling is translated into transcriptional programs for each cell fate remain elusive. We show that a genome organizer, SATB1, activates genes for lineage-specifying factors, including ThPOK, Runx3, CD4, CD8 and Treg factor Foxp3, and Treg factor Foxp3, and CD4, and /CD8, in post-selection thymocytes. Indeed, SATBatb1-deficient thymocytes are partially redirected into inappropriate T lineages after both MHC class-I and -II mediated selection, and fail to generate Treg subset. Despite its essential role in initiating regulatory regions activity in TCR signaled thymocytes. SATBatb1 is becomes dispensable for maintaining ThPOK in CD4+ T cells. Collectively, our findings demonstrate that SATBatb1 shapes the primary T-cell pool by initially directing lineage-specific transcriptional programs in the thymus.
