1.GSE320529 Eomes 维持 CD4⁺ T 辅助祖细胞,从而在免疫治疗期间促进抗肿瘤免疫。

  • 📝 描述:Contributors : Arantxa Agesta ; Chloé Ferrand ; Anne-Louise Le Dorze ; Adeline Chaubet ; Margot Zahm ; Anne S DejeanSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCD4⁺ T helper (Th) cells contribute to tumor immunity, yet the subsets and differentiation programs involved remain unclear. Here, we show that the transcription factor Eomesodermin (Eomes) is essential for Th–mediated anti-tumor immunity by orchestrating the differentiation and maintenance of an exhausted-like Th cell lineage, which is transcriptionally and functionally distinct from conventional effector or memory Th subsets. This Eomes-dependent program is further enhanced by 4-1BB stimulation, promoting effective Th cell–mediated tumor control. The precursor subset of this lineage (pTh) expresses stemness-associated transcription factors, displays self-renewal capacity, and can differentiate into effector cells capable of controlling tumor growth. At the transcriptional level, Eomes supports the survival, metabolic fitness, and apoptotic resistance of this lineage. Notably, Eomes⁺ pTh cells are directly relevant to human cancer, being detected across multiple tumor types, exhibiting conserved transcriptional features, and representing the most expanded Th cell population upon immune checkpoint blockade therapy.

2.GSE335282 通过双重靶向 PCSK9 和先天免疫检查点,增强巨噬细胞连接先天性和适应性抗肿瘤免疫的能力

  • 📝 描述:Contributors : Caili Xu ; Kaicheng Zhou ; Xiaozhi Hu ; Yanyang Nan ; Yun Sun ; Zihan Dou ; Rui Zhou ; Wenjing Xue ; Qinchao Hu ; Xiting Huang ; Xianxin Hua ; Dianwen Ju ; Xuyao ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMacrophage-directed immunotherapy has emerged as a promising strategy to eliminate tumors by unleashing phagocytosis, exemplified by blockade of the CD47-SIRPα “don’t eat me” axis. However, despite robust enhancement of phagocytosis, such approaches often fail to generate durable antitumor immunity in solid tumors, highlighting a critical disconnect between innate immune activation and effective T cell responses. Here, we identify PCSK9 as an adaptive resistance factor induced by macrophage immune checkpoint blockade. Tumor-derived PCSK9 promotes lysosomal degradation of MHC-I in macrophages, thereby impairing antigen cross-presentation and limiting CD8⁺ T cell priming. This previously unrecognized mechanism reveals how phagocytosis-targeted therapies can paradoxically suppress adaptive immunity. To overcome this resistance, we engineered bispecific fusion proteins that concurrently target the CD47-SIRPα phagocytosis checkpoint and the PCSK9–MHC-I antigen presentation axis, among which SIRPαD1-αPCSK9 emerged as the optimal format. Dual targeting synergistically enhances macrophage phagocytosis, preserves antigen cross-presentation capacity, and reprograms the tumor microenvironment toward an immunostimulatory state. Consequently, SIRPαD1-αPCSK9 elicits robust activation of both innate and adaptive antitumor immunity, leading to potent tumor control with improved safety. These findings uncover a novel mechanism of resistance to macrophage-centered immunotherapy and establish a rational dual-targeting strategy that bridges phagocytosis and T cell activation, offering a new paradigm for macrophage-driven cancer immunotherapy.

3.GSE334547 ACKR2 有助于调节骨髓嗜酸性粒细胞,从而促进单核细胞分化和抗菌免疫。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immunity、monocyte、regex:bacter(ia|ial|ium)
  • 📝 描述:Contributors : Gillian J Wilson ; Lily Koumbas Foley ; Zuzanna Pocalun ; Elise Pitmon ; Ayumi Fukuoka ; Kit M Lee ; Lauren Fernandez ; Heather Mathie ; Robin Bartolini ; Laura Medina-Ruiz ; John J Cole ; Gerard J GrahamSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusChemokine receptors control cell migration within the body. Here we reveal interactions between eosinophils and monocytes in the bone marrow, indirectly controlled by the atypical chemokine receptor ACKR2. In the absence of ACKR2, there are decreased numbers of eosinophils in the bone marrow. As a result, eosinophil and monocyte interactions are reduced within the bone marrow niche, and are associated with changes in monocyte gene expression. Monocytes from ACKR2-/- mice are recruited to the tissues but are fundamentally altered in their ability to differentiate into macrophages, in the lung, peritoneal cavity and cavity wall. Bacterial elimination is impaired in ACKR2-/- mice during peritoneal infection. ACKR2 is therefore a key regulator of eosinophil-driven monocyte education in the bone marrow, required for full monocyte differentiation and macrophage function within the tissues.

  • 🏷️ 关键词:carcinoma、single-cell
  • 📝 描述:Contributors : Xing Liu ; Yalun Li ; Lanlan Gao ; Rihui Lu ; Yongjin Fang ; Xiao YangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTo investigate the cellular heterogeneity and molecular drivers of oral squamous cell carcinoma (OSCC), we performed single-cell RNA sequencing (scRNA-seq) on tongue tissues from a 4-nitroquinoline 1-oxide (4-NQO)-induced mouse model. This dataset revealed eight distinct cell populations, with a significant reduction in epithelial cells and an increase in fibroblasts in OSCC compared to controls. Notably, a distinct Col1a1⁺ epithelial subpopulation was identified that exhibited the highest epithelial-mesenchymal transition (EMT) signature and was significantly expanded in OSCC. This study provides a valuable resource for understanding the transcriptional landscape and cellular dynamics underlying OSCC progression.

6. GSE295919 胎儿特异性基因 LIN28B 对人类胎儿 B 淋巴细胞生成和 KMT2A::AFF1 婴儿白血病的发生至关重要 [RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:leukemia、RNA-seq
  • 📝 描述:Contributors : Rebecca Ling ; Thomas Jackson ; Thomas Milne ; Anindita RoySeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensInfant ALL (iALL) is initiated in utero, most often by rearrangement of the KMT2A gene (KMT2Ar). It carries a very poor prognosis despite a lack of additional oncogenic driver mutations common in childhood ALL. Here, we aimed to identify specific properties of human fetal hematopoietic stem/progenitor cells (HSPC) that promote leukemic transformation in KMT2Ar iALL using molecular, functional and in vivo assays. First, by comparing transcriptomes of human fetal HSPC with adult HSPC we derived a fetal-specific gene signature and identified the fetal oncogene LIN28B and its downstream effectors among the top hits. These genes were also expressed in iALL. Functional assays revealed that LIN28B was essential in human fetal liver (FL) CD34+ cells to maintain proliferation and stemness, and support B- and NK-lymphopoiesis. To interrogate the role of LIN28B in iALL, we utilised a human FL-derived CRISPR-Cas9 KMT2A::AFF1 model. In this CRISPRKMT2A::AFF1 model, human FL CD34+ cells fail to transform upon induction of KMT2A::AFF1 translocation in the absence of LIN28B. In addition, LIN28B-expressing CRISPRKMT2A::AFF1 leukemias were more proliferative in vitro and in vivo, with this advantage being lost upon LIN28B knockdown. Mechanistic studies showed that LIN28B acts by stabilizing key early B-lymphoid genes, epigenetic regulators, and cell cycle and anti-apoptotic genes. Thus, LIN28B has an essential role in normal human fetal B-lymphopoiesis, and is necessary for the initiation of KMT2A::AFF1 iALL in fetal cells in the absence of co-operating mutations. LIN28B activity may help explain why KMT2A::AFF1 leukemias are so aggressive, making it a potential target in LIN28B-expressing leukemias.

10. GSE335058 进化引导的转录因子设计程序新的 T 细胞状态 [ChIP-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:T cell、ChIP-seq
  • 📝 描述:Contributors : Oliver Takacsi-Nagy ; Sivakanthan Kasinathan ; Austin Hartman ; Theo L Roth ; Ansuman T SatpathySeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensHuman protein-coding genes evolved via modular rearrangement of domains from ancestral genes. Here, we develop a scalable, evolutionarily guided method to assemble novel protein-coding genes from constituent domains within a protein family, termed DESynR (Domain Engineered via Synthesis and Recombination) genes. Using primary human chimeric antigen receptor T cells as a model, we find that the expression of DESynR Activator Protein-1 (AP-1) transcription factors (TFs) significantly outperforms the overexpression of natural AP-1 TFs in multiple functional assays in vitro and in vivo. Top DESynR AP-1 TFs exhibit non-intuitive domain architectures, including from TFs not canonically expressed in T cells. DESynR AP-1 TFs induce broad transcriptional and epigenetic reprogramming and establish non-natural T cell states that optimize features of exhaustion, effector and cytotoxic function, and persistence— in some cases co-opting gene expression modules from disparate cell types. We show that this reprogramming is primarily driven by differential regulation of established AP-1-bound regulatory elements, rather than unique binding. Finally, we extend the DESynR methodology to Erythroblast Transformation Specific (ETS) and Forkhead box (FOX) TFs to support the generalizability across protein families. Overall, we demonstrate that novel configurations of existing protein domains may uncover non-evolved genes that program cell states with therapeutic relevance.
