1.GSE329527 抗原限制性稳态白色念珠菌 Th17 细胞连接口腔-肠道免疫并适应肠道炎症

How C. albicans drives Th17 responses at homeostasis, and whether such responses contribute to inflammatory diseases, remains poorly understood. Here, we show that C. albicans-reactive Th17 cells exhibit a surprisingly narrow antigen-specificity, targeting a limited set of proteins enriched in fungal extracellular vesicles. At homeostasis, these cells predominantly reside in the oral mucosa. T cell receptor profiling reveals shared clonotypes across oral and gut tissues with C. albicans emerging as the major driver of this repertoire overlap. In Crohn’s disease (CD), C. albicans-specific Th17 cells with features of oral priming are enriched in intestinal tissues where they retain specificity for the same protein targets but acquire pathogenic Th17 traits. Together, our results reveal a stable, antigen-restricted C. albicans Th17 response shared across mucosal sites that undergoes functional adaptation in the inflamed intestine, thus representing a novel target for immune modulation in CD.

2.GSE290480 匹配的单细胞染色质、转录组和表面标志物分析捕获乳腺基底细胞向腔细胞转变过程中的体内表观基因组重编程 [ChIP-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:ChIP-seq、single-cell、transcriptome
  • 📝 描述:Contributors : Eve Moutaux ; Anna Schwager ; Adeline Durand ; Mélanie Miranda ; Louisa Hadj ; Simon Dumas ; Mathias Schwartz ; Marthe Laisné ; Justine Marsolier ; Manuel Guthmann ; Délia Dupré ; Grégoire Jouault ; Mélissa Saichi ; Déborah Bourc’his ; Elisabetta Marangoni ; Nicolas Servant ; Leïla Perié ; Céline VallotSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensSingle-cell multi-omics methods enable simultaneous mapping of chromatin states and transcriptomes, offering deep insights into gene regulation. Yet, the full potential of these approaches remains untapped for rare cell populations, as most methods require thousands of cells and are limited in their ability to capture multiple molecular layers comprehensively within the same cell. Here, we introduce OneCell CUT&Tag a user-friendly method that provides matched high-resolution epigenome, full-transcriptome, and surface marker quantification from every cell, with input as low as one cell. Using this approach, we uncovered epigenomic priming of basal cells in the mammary gland and captured the dynamics of basal-to-luminal transdifferentiation. We identified a transitional cell population with intermediate epigenomic profiles—absent in reference populations—and demonstrated a continuous epigenomic progression from basal to luminal states, while transcriptomes exhibited a binary switch. Adaptable to diverse samples and tissues, this method also revealed the role of H3K27me3 in shaping zygotic expression programs. By matching multiple layers of molecular information at single-cell resolution, OneCell CUT&Tag dissects the complementary roles of each omics layer in shaping cellular identity and function, opening new avenues to study rare and complex biological systems.

4.GSE301718 Mezigdomide 通过降解 Aiolos/Ikaros 和重新激活细胞因子产生途径来逆转 T 细胞耗竭 [Hi-C]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:T cell、cytokine、Hi-C
  • 📝 描述:Contributors : Junfei Zhao ; Hsiling Chiu ; Patrick HagnerSeries Type : OtherOrganism : Homo sapiensGiven the well-established notion that T cells undergo significant changes in their nuclear architecture and chromatin accessibility between different stages of differentiation or phenotypic stage such as activation and exhaustion, we aimed to investigate the chromatin binding patterns of the Ikaros transcription factor, which plays a crucial role in T cell biology and gene regulation, including development, differentiation and activation in response to TCR stimulation. However, a thorough genome-wide analysis of its occupancy and transcriptional regulatory activity between T cell activation and exhaustion has not been performed. To address this, we conducted an integrated epigenomic investigation utilizing Hi-C, ATAC-seq, RNA-seq and ChIP-seq, focusing on Ikaros and histone modifications, including H3K27ac, H3K4me1, and H3K4me3. This approach allows us to understand Ikaros-specific regulation of transcription by characterizing the epigenome in Tact versus Tex cells.
