1. ⭐ GSE295967 单细胞多组学揭示 KRAS 抑制后肿瘤和免疫重塑的协调性 [空间转录组学]
- ✍️ 作者:未知作者
- 🏷️ 关键词:immune、single-cell、spatial、spatial transcriptomics、transcriptomics、KRAS
- 📝 描述:Contributors : Daniel R Lu ; Tracy M Yamawaki ; Shining Ma ; Chi-Ming LiSeries Type : OtherOrganism : Mus musculusAllele-specific KRAS inhibitors are approved for KRAS-mutant cancers, and efforts to maximize patient responses are ongoing. Previous work suggests that KRAS inhibition can modulate anti-tumor immunity, but the critical cellular players and molecular pathways have not been clearly defined. Here we perform multi-omic profiling using single-cell RNA-seq, spatial transcriptomics, and flow cytometry to profile intratumoral changes after KRASG12C inhibition (KRAS(G12C)i), MEK inhibition (MEKi), and combination therapy with KRAS(G12C)i and PD-1 blockade. Treatment with KRAS(G12C)i but not MEKi drove neoplastic adaptation toward increased oxidative stress, integrin signaling, and upregulation of extracellular matrix remodeling factors. These changes were accompanied by changes in spatial intercellular communication patterns, leading to robust cDC maturation and CD8 effector T-cell activation. Combination treatment with anti-PD-1 further expands T-cell responses, as well as macrophage states associated with increased cancer survival. Our findings connect KRAS inhibition with the coordination of subsequent immune activation and reveal molecular mechanisms that promote and sustain tumor control.

3. ⭐ GSE335372 CAR-T药物偶联物抗实体瘤[空间转录组学]
- ✍️ 作者:未知作者
- 🏷️ 关键词:tumor、spatial、spatial transcriptomics、transcriptomics
- 📝 描述:Contributors : Shan Xin ; Yanzhi Feng ; Feifei Zhang ; Chuanpeng Dong ; Sidi ChenSeries Type : OtherOrganism : Homo sapiensChimeric antigen receptor (CAR)-T cell therapy has been clinically successful in hematologic malignancies but faces challenges in solid tumors, including limited infiltration, immunosuppressive microenvironments and antigen heterogeneity. While combining CAR-T cell therapy with chemotherapy can enhance antitumor activity, this often leads to substantial systemic toxicity. Here we show that CAR-T-drug conjugate (CAR-T-D-C), generated through click chemistry-mediated conjugation of cytotoxic payloads to antigen-specific CAR-T cells, enable localized drug delivery while preserving CAR-T cell function. CAR-T-D-Cs incorporating different CAR-T cell binders exhibit robust antitumor activity across multiple human xenografts and syngeneic tumor models. Spatial transcriptomic analyses reveal enhanced intratumoral CAR-T infiltration and activation following CAR-T-D-C treatment . Compared with conventional CAR-T therapy, CAR-T-D-C enhances immune cell infiltration, augments effector functions, promotes antigen spreading and amplifies systemic anti-tumor immunity. CAR-T-D-C represents a versatile therapeutic platform that combines the specificity of cellular immunotherapy with the potency of small-molecule therapeutics for treatment of solid tumors.

5. ⭐ GSE320221 整合细针穿刺和单细胞RNA测序技术研究代谢功能障碍相关脂肪肝疾病
- ✍️ 作者:未知作者
- 🏷️ 关键词:metabolic、sequencing、single-cell
- 📝 描述:Contributors : Ana C Maretti-Mira ; Matthew P Salomon ; Lucy Golden-MasonSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMetabolic dysfunction-associated steatotic liver disease (MASLD) is currently the leading cause of chronic liver disease and hepatocellular carcinoma. The immune response plays a central role in disease onset and progression and is the focus of many experimental studies. However, traditional models typically rely on terminal sampling procedures that require large tissue quantities, substantial numbers of animals per experimental condition, and cross-sectional study designs. Here, we propose the integration of two powerful techniques to longitudinally study a MASLD animal model: image-guided fine-needle aspiration (FNA) and single-cell RNA sequencing (scRNA-seq).

7. GSE313404 单细胞 RNA 测序揭示共生普雷沃氏菌如何通过重编程髓系细胞增强机体对肺炎链球菌肺部感染的防御能力
- ✍️ 作者:未知作者
- 🏷️ 关键词:sequencing、single-cell
- 📝 描述:Contributors : Sara N Stoner ; Eric D Larson ; Sam Fulte ; Erin R Fish ; Steve C Shaw ; Edward N Janoff ; Matthias Mack ; Sarah E ClarkSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusStreptococcus pneumoniae expresses a suite of virulence factors that modulate the innate immune response, delaying effective clearance. However, immune interactions with other bacteria influence this dynamic. Depletion of respiratory tract anaerobes including Prevotella is associated with increased mortality from pneumonia, an effect that can be replicated by pre-exposure to Prevotella melaninogenica in mice. Here, we demonstrate using single-cell RNA sequencing that P. melaninogenica shifts myeloid cell transcriptional profiles during pneumococcal infection from interferon-dominant to pro-phagocytic, correlating with increased S. pneumoniae phagocytosis and clearance from the lung. In neutrophils, improved antibacterial defense was dependent on TNF signaling through TNFR2. Prevotella-enhanced defense also required the recruitment of monocyte-derived macrophages, with selective enrichment of a Cxcl3+ population which differed from the C1qa+ population dominant during S. pneumoniae infection in unprimed mice. This work reveals an optimized innate immune defense program which may contribute to natural infection resistance mediated by respiratory tract commensal-host interactions.
