1. ⭐ GSE320059 Nur77激动剂增强自然杀伤细胞对肝细胞癌的免疫力[空间转录组学]

- 🏷️ 关键词:carcinoma、immunity、spatial、spatial transcriptomics、transcriptomics
- 📝 描述:Contributors : Shi Yong Neo ; Nicholas Ang ; Menaka Rajapakse ; Kong-Peng LamSeries Type : OtherOrganism : Homo sapiens ; synthetic constructDespite promising development as emerging “off-the-shelf” therapeutics against cancer, natural killer (NK) cells still faced considerable challenges in the solid tumor microenvironment (TME) including poor penetrance and immuno-suppression. Here, we employed spatial and single-cell transcriptomics to reveal a role for Nur77 in NK cell-mediated immunity against hepatocellular carcinoma (HCC). The expression of NR4A1, encoding Nur77, is associated with NK cell proliferation, activation of the immunostimulatory AP-1 gene regulons and better disease-free survival in HCC. Conditional ablation of Nr4a1 in NK cells perturbed their homeostasis and accelerated tumor progression in multiple tumor models while the agonistic activation of Nur77 in NK cells ex-vivo or in-vivo enhanced their anti-tumor functions. Mechanistically, Nur77 activation attenuated CD36 expression in NK cells and conferred resistance against oxLDL-mediated immunosuppression in the TME. Collectively, our findings highlighted the potential of harnessing Nur77 agonism in improving NK cell-based immunotherapy against tumors.

- 📝 描述:Contributors : Rosa Nguyen ; Robert Edinger ; Constanza Rodriguez ; Xiyuan ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensChimeric antigen receptor (CAR) T-cell therapy has limited efficacy against solid tumors such as neuroblastoma (NB). Key obstacles include extensive tumor burden and the presence of an immunosuppressive tumor microenvironment (TME). We employ targeted radiopharmaceutical therapy (RPT) using [67Cu]Cu-LLP2A and find that it potentiated the anti-tumor activity of CAR T-cells in radio-sensitive and radio-resistant NB models via distinct mechanisms. In radio-sensitive NB, RPT is directly tumoricidal while also enhancing CAR T-cell efficacy through pro-immune pathways, most notably via the TNFα pathway, leading to paracrine activation of T-cells. In radio-resistant NB, RPT improves CAR T-cells by remodeling the myeloid compartment in the TME and increasing the formation of immunological niches of cytotoxic CD8⁺ GZMB⁺ and CD4⁺ GZMB+ CAR T-cells. While neither treatment modality alone can effectively treat NB, the combination of VLA-4-targeted RPT and GD2 or B7-H3 CAR T-cells augments anti-tumor efficacy, resulting in marked tumor regression in preclinical NB models.

- ✍️ 作者:未知作者
- 🏷️ 关键词:macrophage、inflammation、spatial
- 📝 描述:Contributors : Yufan Zheng ; Hannah E Dobson ; Makheni J Pierre ; Lilly LeBlanc ; Dominic P Golec ; Nathan Carrillo ; Anshu Deewan ; Claudia R Cifuentes ; Eduard Ansaldo ; Eric V DangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusEffective pulmonary immunity requires the precise spatial organization of immune cells, yet the mechanisms guiding their intratissue positioning during inflammation remain unclear. Here, we identify a cholesterol-derived chemotactic axis that spatially organizes T helper 2 (TH2) cells during fungal-induced pulmonary type 2 inflammation. Inflammation-expanded macrophages expressing cholesterol-25-hydroxylase (CH25H) produce 25-hydroxycholesterol, which is converted into the oxysterol 7α,25-dihydroxycholesterol to attract GPR183-expressing TH2 cells into inflammatory Ly6C+ macrophages, promoting fungal persistence. Disruption of this axis via TH2- specific GPR183 deletion restores type 1 macrophage activation and enhances fungal clearance. Our findings reveal a macrophage-driven, metabolite-based mechanism of immunosuppressive cell positioning in inflamed lung tissue.

Innate immunity provides frontline defense after birth and is shaped in part by myeloid-derived suppressor cells (MDSCs). The role of MDSCs in regulation of neonatal immunity, especially in the context of prematurity, remains elusive. We sought to understand the transcriptional landscape of neonatal immune myeloid regulators, specifically differences between preterm and full-term neonates. Insight into specific cellular networks could help understand how to skew preterm MDSCs’ development towards classical immunotolerant and anti-microbial mechanisms. Methods: This cross-sectional study used single-cell RNA sequencing to characterize the neonatal MDSC transcriptional landscape, developmental trajectories, and predicted signaling networks within 48 hours after birth. Peripheral blood mononuclear cells were isolated from 7 preterm neonates (37 weeks), and 6 healthy adult (21-45 years old, control). Primary exposure was premature birth and neonatal intensive care hospitalization from a single-center, academic tertiary care hospital between 2023 – 2024. Results: Among ~339,000 cells, preterm neonates exhibited enrichment of polymorphonuclear MDSCs (10.6%±5.3%) vs full-term (2.6%±1.3%) and adults (0.4%±1.3%). Trajectory analysis identified a prematurity-associated differentiation branch characterized by inflammatory signaling, mitochondrial stress, and heightened protein-translation programs, distinct from a conserved, tolerogenic MDSC trajectory present across ages. Cell-communication modeling showed intensified outgoing and incoming signaling via ADGRE, RESISTIN, TGF-β, ANNEXIN, and ICAM networks. Antigen presentation signatures suggested preserved MHC-I output and diminished MHC-II interactions in neonates, with increased MHC-I input to preterm polymorphonuclear MDSCs. Conclusions: Prematurity is associated with early divergence of MDSC maturation toward an inflammatory and metabolically stressed PMN-MDSC state with altered immune communication. These findings identify cellula…

- 📝 描述:Scientists have uncovered a hidden “sugar code” on the surface of human cells that could transform how diseases are detected. Using an advanced imaging technique called Glycan Atlasing, researchers at the Max Planck Institute mapped the tiny sugar structures coating cells and discovered that these patterns shift depending on what the cell is doing. Immune cells changed their sugar layouts when activated, and cancerous tissues displayed distinct surface signatures compared to healthy tissue.
