1.GSE329048 巨噬细胞介导的 IL1beta/IL23 信号传导调节针对非结核分枝杆菌的 γ δ (γδ) T 细胞免疫 [脾脏 RNA-seq]。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immunity、T cell、macrophage、RNA-seq
  • 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMechanistic Insights. Our study reveals the crucial role of gammadelta T cells in non-tuberculous mycobacteria (NTM) infection. We observed a significant increase and activation of gammadelta T cells in mice infected with MAB or with MAB infection combined with pulmonary fibrosis. Depletion of gammadelta T cells worsened the infection, while transfer of gammadelta T cells reversed this effect. Mechanistically, we found that MAB infection stimulates macrophages to produce IL-1beta and IL-23, which promotes the expansion of gammadelta T17 cells. MAB can also directly activate gammadelta T cells, leading to the clearance of MAB through an IL-17A-dependent pathway. Our findings suggest that gammadelta T cells represent a potential therapeutic target for NTM infections.

  • 📝 描述:Contributors : Anne Dejean ; Liliana Lucca ; Arantxa Agesta ; Chloé Ferrand ; Anne-Louise Le Dorze ; Nadège Carrié ; Arthur Palak ; Ludovic MartinetSeries Type : Other ; 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.

3.GSE314004 通过整合单细胞 RNA 测序、光谱免疫表型分析和机器学习来解码新诊断癌症中的免疫失调

Circulating immune biomarkers provide a promising, non-invasive diagnostic opportunity, yet their potential remains insufficiently defined. Here, we present an integrated multi-omics analysis of peripheral blood mononuclear cells (PBMCs) from treatment-naïve cancer patients, combining immune phenotyping (flow cytometry, FC), multiplex cytokine profiling, and single-cell RNA sequencing (sc-RNA-seq). Compared with healthy controls, patients exhibited widespread immune dysregulation, including expansion of FOXP3+ regulatory T cells, depletion of CD16+CD11b+ monocytes and CD56dim NK cells, and elevated plasma IL-6/IL-4 levels. Sc-RNA-seq identified novel cancer-specific immune signatures, notably consistent upregulation of THBS1 and CH25H, indicative of systemic imprinting by tumor-derived cues. Deep learning models integrating single cell multi-omics data (sc-FC + sc-RNA-Seq) achieved performance comparable to clinical models, enabling cancer-type stratification and mechanistic insight. These findings establish a framework for immune-based, multi-omics diagnostics in early cancer detection and disease monitoring.

5.GSE277610 内皮细胞PD-L1抑制CD8+ T细胞耗竭,增强非小细胞肺癌的抗肿瘤免疫力

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、immunity、T cell
  • 📝 描述:Contributors : Peter Carmeliet ; Lisa M Becker ; Anh-Co K Truong ; Julia DmitrievaSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCancer immunotherapies targeting PD-(L)1 offer therapeutic potential but suffer resistance. The role of PD-L1 in tumor and myeloid cells has been extensively studied, while its function in tumor endothelial cells (ECs) is overlooked. Surprisingly, we identified an unknown role of EC-specific PD-L1 in delaying the exhaustion of tumor-infiltrating CD8+ T cells in a non-small cell lung cancer mouse model. Loss of endothelial PD-L1 reduces T cell activation and exac-erbates tumor growth. Initial inhibition of CD8+ T cells by endothelial PD-L1, prior to encoun-tering cancer cells, prevents T cells from prematurely reaching a terminal exhaustion state. Initial results suggest that high EC PD-L1 expression in NSCLC patient tumors might become a potential positive predictor of anti-PD-1 outcome. These unexpected findings highlight the significance of vessel-associated PD-L1 and suggest that EC PD-L1 blockade upon systemic treatment potentially negates the overall therapeutic effect, raising the question if this might contribute to therapy resistance.

6.GSE331107 转录因子 AFF3 对于维持初始 CD8 T 细胞的代谢静止状态和防止过早的免疫衰老是必需的

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:immune、aging、metabolic
  • 📝 描述:Contributors : Molly E Lumnitzer ; Stefanie F Valbon ; Stephanie A Condotta ; Allison E Norlander ; Sheng Liu ; Jun Wan ; Martin J RicherSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusNaïve CD8 T cells must be maintained in a quiescent metabolic state in order to respond robustly to infection while avoiding inappropriate activation and causing immunopathology. With age this quiescent state is lost and the CD8 T cell response to infection decreases. The factors regulating metabolic quiescence of CD8 T cells and how this regulation is lost during aging are not completely understood. Herein, we identify the transcription factor AFF3 as a novel regulator of metabolic quiescence in naïve CD8 T cells. While naïve AFF3 deficient CD8 T cells are more metabolically active prior to infection, they have reduced accumulation in response to viral infection and this is correlated with a poor capacity to engage glycolysis. During aging in both murine and human CD8 T cells, AFF3 expression is reducing, correlating with to a loss of quiescent metabolism without the cells entering an activated state. Our data highlights the role of the metabolism in CD8 T cell quiescence and identifies a novel transcription factor that may be a target to reinvigorate CD8 T cell responses during aging.

9.GSE306559 胶质瘤细胞系中m6A mRNA甲基化对替莫唑胺耐药性的调控

  • 🏷️ 关键词:glioma、resistance、methylation
  • 📝 描述:Contributors : Sigrid Nachtergaele ; Emily Dangelmaier ; Dorthy Fang ; Kyal Sin Htet ; Nicole S Harry ; Renee Pascoe ; Je Won Yang ; Clara WangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensN6-methyladenosine (m6A) is a critical regulator of mRNA processing and function, playing roles in mRNA processing, translation, and decay. Changes in m6A status have been implicated in various cancers, including glioblastoma (GBM), where acquired chemoresistance to temozolomide (TMZ) remains a major clinical challenge. We developed cell culture models of acquired TMZ resistance in GBM and analyzed the regulation of resistance-associated genes and pathways by m6A. We find that key resistance-associated genes and pathways are regulated by m6A methylation, including MGMT, the enzyme that repairs primary TMZ-induced DNA damage. Inhibition of METTL3 with STM2457 treatment destabilizes MGMT mRNA. Intriguingly, other TMZ resistance-associated genes are similarly regulated by m6A, suggesting that METTL3 inhibition may represent a promising therapeutic approach for overcoming TMZ resistance.

10.GSE288623 霍奇金淋巴瘤肿瘤相关巨噬细胞体外模型的转录谱

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、lymphoma、macrophage
  • 📝 描述:Contributors : Maciej Szydlowski ; Michal PawlakSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensTumor-associated macrophages (TAMs) of classic Hodgkin Lymphoma (cHL) contribute to the development of immunosuppressive tumor microenvironment (TME) and are associated with worse treatment outcome. However, detailed features and functions of cHL TAMs and their therapeutic vulnerabilities remain largely unknown. To gain deeper insight into the biology of TAMs in cHL, we analyzed diagnostic biopsies by Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) and assessed transcriptional, proteomic and metabolic profiles of the in vitro TAM models. We show that Reed-Sternberg (RS) cells of cHL induce disease-specific TAM phenotype, characterized by elevated expression of factors involved in chemotaxis, angiogenesis, extracellular matrix remodeling and tumor immune escape. Importantly, RS cell-conditioned TAMs expressed TGFβ, CCL17 and tryptophan catabolizing enzymes, IDO1 and IL4I1, facilitating induction or and/or recruitment of Tregs. In addition, we identified PIM1/2/3 kinases in cHL TAMs. We characterized PIMs as important hubs orchestrating RS-macrophage interactions. Pharmacological PIM blockade attenuated development of TAM transcriptional profile and phenotype induced by RS cells. In established TAMs, PIM inhibition or PROTAC-mediated degradation decreased expression of multiple factors associated with pro-tumoral TAM functions, including IL8, MMP9, CHI3L1/2, CD206, CD209, PD-L1, CCL17, TGFβ, IL4I1 and IDO1. PIM blockade attenuated TAM-dependent eosinophil chemoattraction, extracellular matrix remodelling, angiogenesis and regulatory T cell development. Taken together, our study highlights the role of PIMs in regulation of TAM activities involved in cHL pathogenesis and potentially relevant for response of cHL patients to immunotherapies.
