1.GSE283872 先前高纤维摄入对肠系膜脂肪和肠道组织对随后高脂肪喂养的细胞反应产生影响[空间转录组学]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics、regex:intestin(e|al)
  • 📝 描述:Contributors : Zhi Peng ; Meng XieSeries Type : OtherOrganism : Mus musculusDietary modification by consuming plant-based food with high fiber content is a primary strategy to induce weight loss in obese individuals. However, long-term usage of such fiber-enriched dieting is challenging and rapid weight regain often occurs once the high-fat dietary habit resumes. Currently, how do adipose and intestinal tissues respond to a switch between high-fiber and high-fat diet remains unknown. Here, we applied C57BL/6J mice to chow diet (CD)/high-fiber diet (HfiD)-to-high-fat diet (HFD) switching paradigms and collected mesenteric white adipose tissue (mWAT), duodenum and colon tissue sections at different time points for single-nucleus profiling and spatially resolved transcriptomic analysis, respectively. We show that the progenitors and adipocytes of HfiD-fed mWAT are more sensitive to HFD-induced molecular changes. In addition, HfiD feeding prevents the subsequent HFD-induced expansion of immune-related enterocytes in duodenum and reverses the HFD-induced enterocyte-to-goblet cell conversion in colon. Moreover, HfiD-induced microbiome changes are mostly abrogated upon HFD feeding. Our results indicate that prior HfiD feeding can alter the cellular response of adipose and intestinal tissues to subsequent HFD feeding, which highlights the impact of dietary interventions with fiber-rich food for obesity treatment from a different perspective. Our data provide a spatiotemporal resource for future hypothesis-driven studies on the mechanisms of adipose and intestinal tissue plasticity in response to diet switches.

Macrophages, fundamental components of these lesions, are crucial to TB pathogenesis, yet their phenotypic and functional diversity remains incompletely understood. Here, we used single-cell RNA sequencing and immunofluorescence to profile macrophages in lung tissue and granulomas from a nonhuman primate model of early TB. We identified transcriptionally distinct subsets, including embryonic-origin tissue-resident alveolar macrophages and monocyte-derived alveolar and interstitial macrophages, each with distinct spatial localization in granulomas. Tissue-resident alveolar macrophages and a subset undergoing epithelial-to-mesenchymal transition accounted for the highest frequency of Mtb-infected cells. Infected cells exhibited differential expression of immune- and migration-associated genes compared to uninfected counterparts, suggesting Mtb either induces or exploits these pathways as a survival strategy. These findings highlight macrophage heterogeneity as a major driver of differential susceptibility to Mtb and provide insights relevant to future immunomodulatory strategies.

4. GSE282411 半乳糖凝集素-9通过树突状细胞内HLA-DR结合调节CD4+ T细胞增殖

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:T cell、HLA
  • 📝 描述:Contributors : Andrea R Furones ; Guido van Mierlo ; Laia Q CanoSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensTo initiate T cell-mediated immunity, dendritic cells (DCs) present antigen to specific T cells through the establishment of an immune synapse. Despite its critical importance, the spatiotemporal dynamics of membrane receptor organization during synapse formation in DCs have been only partly characterized. Galectins, a family of β-galactoside binding proteins, exert crucial roles in homeostasis and pathological processes but the molecular mechanisms underlying galectin function are largely unresolved. Here, we demonstrate that intracellular galectin-9 (gal9) is required for T cell activation. Murine and human DCs lacking gal9 showed impaired induction of CD4+, but not CD8+, T cell proliferation, suggesting a conserved function for gal9 in modulating DC–T cell interactions. Live-cell imaging further revealed that galectin-9-depleted DCs fail to establish stable immunological synapses with T cells, resulting in reduced T cell clustering and activation. Unbiased co-immunoprecipitation and mass spectrometry identified HLA-II as a gal9 binding partner in DCs, and we observed a marked reduction of HLA-II recruitment to the immune synapse as the underlying mechanism. Conditional gal9 knockout in DCs led to enhanced tumor growth, compared to their WT counterparts, underscoring galectin-9 role in T cell-dependent anti-tumor immunity. Collectively, this study provides the first detailed account of gal9-mediated HLA-II organization at the synaptic site of DCs, revealing a novel mechanism by which galectins orchestrate immune receptor positioning from within the cytoplasm to enhance CD4+ T cell activation.

  • 🏷️ 关键词:transcriptome、regex:intestin(e|al)
  • 📝 描述:Contributors : Amy E. O’Connell ; Radhika Khetani ; Shannan Ho SuiSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusIn the first postnatal month, the developing mouse intestine shifts from an immature to a mature intestine that will sustain the organism throughout the lifespan. Here, we surveyed the mouse intestine in C57Bl/6 mice by RNA-Seq to evaluate the changes in gene expression over time from the day of birth through 1 month of age in both the duodenum and ileum. We analyzed gene expression for changes in gene families that correlated with the periods of NEC susceptibility or resistance. We highlight that increased expression of DNA processing genes and vacuolar structure genes, tissue development and morphogenesis genes, and cell migration genes all correlated with NEC susceptibility, while increases in immunity gene sets, intracellular transport genes, ATP production, and intracellular metabolism genes correlated with NEC resistance. Using trends identified in the RNA analyses, we further evaluated expression of cellular markers and epithelial regulators, immune cell markers, and adenosine metabolism components. We confirmed key changes with qRT-PCR and immunofluorescence. In addition, we compared some findings to humans using human intestinal biopsies and organoids. This dataset can serve as a reference for other groups considering the role of single molecules or molecular families in early intestinal and postnatal development.

6. GSE281101 RASD1 抑制 GM-CSF 信号网络以赋予免疫抑制性肿瘤微环境 [MC38]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、tumor microenvironment
  • 📝 描述:Contributors : Kyu-Hye Chun ; Bo Kyung Yoon ; Mi-Young Kim ; Hyunsik Kim ; Sugyeong Jo ; Tae-Hyun Kim ; Hyeonuk Jeon ; Nahee Hwang ; Hyeonhui Kim ; Hyunki Kim ; Jae-Ho Cheong ; Sungsoon Fang ; Jae-woo KimSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCancer immunotherapy is an emerging treatment, particularly for malignant tumors; however, resistance poses a significant challenge. Using the gastric cancer stem-like subtype, known for its poor clinical outcomes, this study explores how glucocorticoid receptor (GR) signaling via the target gene RASD1 promotes tumor progression and immune evasion, positioning RASD1 as a potential target for immunotherapy. We investigated the transcriptomic features of 497 patients with gastric cancer. Syngeneic mouse models were generated using cancer cells with modulated RASD1 expression, a gene that is highly upregulated in the stem-like subtypes. These models were treated with immunotherapy and analyzed using single-cell RNA sequencing. To overcome immunotherapy resistance, GM-CSF was co-administered with anti-PD1 to improve the efficacy of RASD1-overexpressed tumors. Elevated RASD1 promotes tumor growth and resistance to anti-PD1 therapy. Immune profiling of RASD1-overexpressing tumors revealed an increase in the number of myeloid derived suppressor cells (MDSCs) and a decrease in the number of cytotoxic CD8+T cells. GM-CSF treatment reduced tumor growth and MDSC levels, which were upregulated by the downregulation of RASD1. Combined GM-CSF and anti-PD1 treatment suppressed tumor growth by increasing the number of cytotoxic CD8+GZMB+ T cells. Tumor progression driven by RASD1-induced immunosuppression highlights the need for additional treatments beyond anti-PD1 treatment. RASD1 promotes immune evasion by facilitating MDSC accumulation and skewing the tumor microenvironment toward an immunotherapy-resistant state. GM-CSF reverses the immunosuppressive effects and restores effective anti-tumor immune response.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、immunity
  • 📝 描述:Contributors : Bowen Xie ; Xiaohong Zhao ; Tian XieSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusType 1 conventional dendritic cells (cDC1s) capture antigens in peripheral tissues and migrate to draining lymph nodes (dLNs) to prime antigen-specific CD8+ T cells. How tumor antigens are processed for activating CD8+ T cell immunity are not well understood. Here, we found that Ms4a7 was selectively expressed in cDC1s after engulfing tumor antigens or exposed to exogenous antigens, and required for their cross-priming ability and migration to dLNs. Ms4a7-/- mice showed normal cDC1 development and turnover but failed to prime antigen-specific CD8+ T cells after infection or tumor development. In human cancers, MS4A7 specifically expressed in a subset of cDC1s which preferentially enriched in dLNs, playing a crucial role in patient survival. Our findings reveal a critical role of Ms4a7 in cDC1 migration, cross-presentation and anti-tumor CD8+ T cell responses.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:sequencing、single-cell
  • 📝 描述:Contributors : Sara Viragova ; Pierangela Palmerini ; Piero DalerbaSeries Type : OtherOrganism : Mus musculusThe major salivary glands (SG) are exocrine glands responsible for the physiological production of saliva, a sero-mucinous fluid that plays a key role in the digestion and swallowing of food, the articulation of speech and the maintenance of oral hygene. Among the principal causes of SG dysfunction is radiation treatment of head-and-neck malignancies, which can cause severe damage to multiple cell-types within the SG epithelium, resulting in permanent loss of saliva production and substantial disability. The aim of this study is to analyze the cellular composition of the mouse SG epithelium using single-cell RNA-sequencing (scRNAseq) in order to: 1) gain a deeper understanding of the rich repertoire of different epithelial cell-types that coexist witin it; and 2) to elucidate whether different sub-types of epithelial cells display different radiosensitivity and are preferentially elimininated from SGs following radiotherapy. The dataset includes data from scRNAseq experiments performed on the epithelial compartment (Epcam+) of mouse adult sub-mandibular glands (C57BL/6J, female), either at baseline (wild type) or following stereotactic X-ray irradiation (30 Gy). In the specific case of wild-type mice, the dataset also includes data from a secind scRNAseq experiment performed on the basal compartment (Epcam+, Cd49f-high) of the sub-mandibular gland, which is postulated to contain a minority population of epithelial cells with stem-progenitor properties.
