  • 📝 描述:Contributors : Heather Mathie ; Laura Medina-Ruiz ; Fabian Schuette ; Heba Halawa ; Zuzanna Pocalun ; Elise Pitmon ; John Cole ; Marieke Pingen ; Gerard J GrahamSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusInflammatory chemokine receptors CCR1, CCR2 and CCR5 are critical for directing recruitment of monocytes and macrophages in the context of inflammation. However, the discrete role for each receptor in monocyte/macrophage biology remains poorly understood, with previous reports citing receptor redundancy. Here, we have used transcriptomic approaches to examine inflammatory chemokine receptor expression on lung interstitial macrophage populations. We have demonstrated that interstitial macrophages can be divided into three distinct subsets, each of which express specific patterns of chemokine receptors, and that there are dynamic changes in chemokine receptor expression as macrophages differentiate from monocytes in the lung. Furthermore, macrophages expressing different combinations of chemokine receptors are transcriptionally distinct from one another, suggesting non-redundant functions for CCR 1, 2 and 5. Finally, we examined changes in macrophage chemokine receptor expression in vitro after treatment with varied TLR ligands, and show that CCR1 is specifically increased in response to bacterial but not viral ligands. Our data provide compelling evidence that macrophage chemokine receptor expression is not redundant, but specific and maleable in response to discrete inflammatory stimuli.

3.GSE318171 营养响应型和 DAF-16/FoxO 靶向 H1 组蛋白 HIL-1 促进秀丽隐杆线虫对饥饿和细菌病原体的抵抗力

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:regex:bacter(ia|ial|ium)、resistance、histone
  • 📝 描述:Contributors : Kinsey C Fisher ; Rojin Chitrakar ; Ryan BaughSeries Type : Expression profiling by high throughput sequencingOrganism : Caenorhabditis elegansInsulin/IGF-1 signaling (IIS) mediates metabolic and developmental acclimation to stressful conditions including starvation. The transcription factor DAF-16/FoxO actuates many of the physiological effects of reduced IIS, yet the specific contributions of DAF-16 target genes to stress resistance remain poorly understood. We explore the function of C. elegans H1 linker histone variant hil-1/H1.0, a DAF-16 target that is upregulated during starvation. The HIL-1 sequence is divergent from the other eight annotated C. elegans H1 variants, and the others are not so highly responsive to nutrient availability and DAF-16 activity, suggesting distinct function. Using knock-in reporters, we find that HIL-1 is expressed ubiquitously in nuclei of L1 and dauer larvae during starvation, but that expression is largely undetectable in fed larvae. Disrupting hil-1 activity through mutation or auxin-inducible degradation led to reduced growth after extended L1 starvation, revealing reduced starvation resistance. RNA-seq of hil-1 mutants showed that hil-1 affects expression of relatively few genes. However, hil-1 activates genes involved in the innate immune response, Pseudomonas aeruginosa infection, and components of the nipi-3/TRIB1 immunity pathway. hil-1 mutants display compromised survival upon exposure to P. aeruginosa under reduced IIS, and genes activated by hil-1 promote resistance to P. aeruginosa. Together these results suggest that DAF-16/FoxO activates transcription of hil-1 during starvation to promote resistance to starvation and pathogens. We demonstrate conditional regulation of an H1 histone, and we reveal a novel mechanism for how IIS promotes stress resistance by identifying a histone variant that connects nutrient sensing to immunity.

7.GSE301343 NQO1介导的胶质母细胞瘤氧化应激抵抗和肿瘤微环境重塑

  • 🏷️ 关键词:tumor、tumor microenvironment、resistance
  • 📝 描述:Contributors : Yangqing Li ; Tao Kang ; Zhen Jia ; Chenfei Lu ; Gaoyuan Cui ; Hang Yu ; Deobrat Dixit ; Fangshu Jin ; Danyang Shan ; Qiankun Lin ; Daqi Li ; Hao You ; Danling Gu ; Jiancheng Gao ; Zhumei Shi ; Wei Gao ; Fan Lin ; Zhe Zhu ; Qianghu Wang ; Weiwei Tao ; Junxia Zhang ; Jingshan Liang ; Yongping You ; Xu Qian ; Kailin Yang ; Xiuxing Wang ; Kun Yang ; Luan Sun ; Chaojun Li ; Qian ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensBackground: Glioblastoma (GBM) is a highly aggressive brain tumor, with glioblastoma stem cells (GSCs) occupying the pinnacle of a complex tumor microenvironment (TME), conferring therapeutic resistance. The TME plays a role in tumor development by creating a niche rich in reactive oxygen species (ROS) through oxidative stress (OS). Here, we identified NAD(P)H quinone oxidoreductase-1 (NQO1) as an essential regulatory factor in antioxidant stress response, which is key to maintaining GSCs and the immunosuppressive TME. Methods: Proteomics analysis, epigenetic profile by using H3K27ac ChIP-sequencing and single-cell RNA sequencing were performed to define the high enrichment of NQO1 in GBM. In vitro and in vivo loss-of-function genetic and pharmacologic assays were conducted to evaluate the effect of NQO1 in GSC proliferation and self-renewal. Patient-derived GSCs and a xenograft murine model were using to investigate the tumor-intrinsic and extrinsic mechanisms to confers resistance to oxidative stress and reprogram the immunosuppressive TME. Results: NQO1 was preferentially expressed in GSCs and regulated ROS levels, preserving the stability of nuclear Lamin B1 and inhibiting cGAS-type I interferon signaling, which helps to remodel the immunosuppressive TME. Furthermore, nuclear factor erythroid 2-related factor 2 (NRF2) transcriptionally regulates NQO1, suppressing type I interferon signaling. Conclusions: NQO1 plays critical roles at both the cell-autonomous and cell-extrinsic levels for clinical treatment. Targeting NQO1 and its downstream signaling pathways, including β-Lapachone and immune checkpoint inhibitors such as anti-PD-1 therapy, enhances our understanding of the interactions between GSCs, oxidative stress, and the TME. This offers promising new avenues for clinical intervention in GBM.

8.GSE333350 治疗性细菌训练的NK细胞可提供针对癌症转移的长期保护

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、bacteria、regex:bacter(ia|ial|ium)
  • 📝 描述:Contributors : Li Rong ; Jingchu Hu ; Wei Jin ; Jiandong HuangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusWe report that a single dose of therapeutic Salmonella, a prominent anti-tumor bacterial therapy, provides long-lasting protection against metastasis in mice by inducing trained NK cells. Integrated functional and multi-omics analyses revealed that Salmonella-trained NK (stNK) cells establish an enduring reprogrammed epigenome characterized by enhanced pro-survival signaling and immune effector functions, resulting in more potent IFN-gamma release and cytotoxicity upon secondary stimulation. We further showed that this training requires a transient pulse of IL-12 combined with sustained IL-18 signaling. Crucially, stNK cells significantly outperform conventional immune checkpoint therapies, including PD-1 and TIGIT blockade, in preventing metastasis, underscoring the unique immunological mechanisms in combating metastasis.

9.GSE268993 肠道上皮细胞Ceacam1缺陷可预防类固醇难治性急性肠道移植物抗宿主病

  • 🏷️ 关键词:gut、regex:gut(-?microbiome)?、regex:intestin(e|al)
  • 📝 描述:Contributors : Qingxiao Song ; De F ZengSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusSteroid refractory gut acute graft-versus-host disease (SR-Gut-aGVHD) is the major cause of non-relapse death after allogeneic hematopoietic cell transplantation, due to poor understanding its pathogenesis. We recently reported that increase of donor-type IL-22+ T cells, IL-22-dependent dysbiosis, and loss of anti-inflammatory CX3CR1hi mononuclear phagocytes (MNP) play critical roles in SR-Gut-aGVHD pathogenesis, but the mechanisms remain unclear. Ceacam1 on intestinal epithelial cells (IECs) is proposed to regulate bacterial translocation and subsequent immune response in the gut tissues. Here, with imaging mass cytomtory (IMC), combined scRNA-Seq and ATAC-Seq, as well as high dimensional flow cytometry analysis, we show that Ceacam1 expression is enhanced on IECs in murine and human SR-Gut-aGVHD. Ceacam1 deficiency on host IECs effectively prevents SR-Gut-aGVHD in murine models. Ceacam1 deficiency on IECs results in 1) increase in frequencies of IL-22+IL-10+Foxp3+CD4+ peripheral Tregs (pTregs) while reducing conventional IL-22+CD4+ T (Tcon), Th/Tc1, and Th17 cells; 2) increase of beneficial commensal bacterial that augment colonic pTregs expansion, while reducing pathogenic bacteria and blocking E. Coli’s interaction with IECs; and 3) increase of anti-inflammatory CD103-CX3CR1hi MNP that produce IDO and IL-10, while reducing pro-inflammatory CD103+CX3CR1lo MNP that produce IL-6. Thus, specific targeting IEC Ceacam1 represents a novel approach for prevention of SR-Gut-aGVHD.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:sequencing、single-cell、scRNA
  • 📝 描述:Contributors : Yongchun Zhang ; Rongzi MuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusHippo signaling plays a crucial role in the development of multiple organs. This study consists of two transcriptomic datasets.Single-cell RNA sequencing was conducted on E18.5 mouse hindstomach epithelial cells of littermate control, YAP5SA-overexpressing and Yap knockout mice, where YAP5SA represents a constitutively active form of Yap. Bulk RNA sequencing was performed to analyze transcriptional changes in 3D organoids derived from the glandular embryonic hindstomach epithelium of control and YAP5SA-overexpressing mice. Among these, organoids were cultured under two conditions: growth medium for 5 days, or growth medium for 5 days followed by differentiation medium for an additional 7 days. Comparative gene expression profiling provides valuable insights into the role of the Hippo signaling pathway in regulating diverse biological processes during glandular stomach epithelial development.
