Specifically, trithorax group (TrxG) and polycomb group (PcG) components play crucial roles in transcriptional activation and repression of state-specific stem cell expression programs, yet the mechanisms underlying their selective genomic binding remain poorly understood. In this study, we report that the polycomb repressive complex 1 (PRC1) subunit RYBP co-localizes with TrxG component WDR5 and selectively enriches PcG component RING1B in condensates in murine embryonic stem cells (ESCs). RYBP deficiency impairs the genomic binding of WDR5 and RING1B. Further, STAT3 excludes RING1B binding at RYBP-associated transcriptionally active loci. Additionally, RYBP depletion attenuates WDR5-dependent activation of DNA repair gene expression and facilitates the transition of ESCs to 2-cell-like cells. Finally, RYBP depletion disrupts RING1B deposition at lineage-specific genes, promoting ESC differentiation towards mesendoderm fate. These findings uncover RYBP as a regulator of selective genomic binding of TrxG and PcG components, providing insights into their roles in cell fate determination during development.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147754700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we discovered that NSC quiescence exit in Drosophila follows a hierarchical sequence, whereby activation of anterior stem cells in the brain lobes precedes and is required for the timely state-transition of more posterior NSCs in the ventral nerve cord. To achieve this, quiescent NSCs transiently activate neuronal genes. This transient neuronal state is temporary and specific to NSC dormancy, as neuronal genes are switched off after stem cells resume proliferation. Blocking neuronal firing in brain lobe neurons delays the onset of posterior NSC reactivation. Our results reveal long-range communication between quiescent NSCs to coordinate reactivation across the CNS, enabled by a transient, plastic neuron-like state that allows direct interaction with neuronal axons.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"244 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147739092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrative bioinformatic analyses identify that SEC16B co-emerges with core genes involved in lipoprotein biogenesis. Functional studies, coupled with AI-driven prediction, reveal that SEC16B acts as a molecular brake to fine-tune COPII condensation for lipoprotein export. Mining of UK biobank data links SEC16B to metabolic traits in humans and suggests HNF4A-dependent regulation of SEC16B expression. Hepatic deletion of SEC16B in mice markedly reduces circulating APOB, triglycerides and cholesterol, while conferring robust protection against atherosclerosis and cardiac dysfunction and maintaining liver health.

Here we determined a cryo-EM structure of human SLC1A1 bound to compound 3e, a recently described SLC1A1-selective bicyclic imidazo[1,2 α]pyridine-3-amine (BIA) inhibitor with an unclear mechanism of action. 3e binds a membrane-embedded allosteric pocket accessible only in the apo state, when SLC1A1 is unbound to substrate and sodium, and likely prevents sodium and substrate binding. Moreover, by forming a wedge between the trimerization domain and the substrate-binding transport domain, alongside a cholesterol moiety from the lipid bilayer, 3e blocks SLC1A1's elevator-like movements that support the transport cycle. Mutations in this binding pocket abolish the 3e interaction and counteract 3e's cytotoxicity in RCC cells, confirming on-target activity and explaining SLC1A1 selectivity. The subsequent design of two new SLC1A1-selective BIA derivatives, PBJ1 and PBJ2, was directed by the SLC1A1-3e structures; both inhibited SLC1A1-dependent aspartate, glutamate, and cysteine metabolism and showed enhanced cytotoxicity.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have uncovered their contribution to antigen surveillance and immune signalling. To further explore how protrusions initiate signalling pathways mediating T-cell activation, we performed live-cell imaging of endogenously tagged proteins in HER2-specific chimeric antigen receptor (CAR) T cells targeting HER2⁺ breast-cancer cells. Quantitative STED microscopy allowed us to monitor protein rearrangement and to correlate it with membrane topology over time. Before activation, key signalling proteins (including Lck, CD45, LAT, and the CAR) were not enriched in protrusions. Upon contact with target cells, rapid protein reorganisation occurred preferentially within protrusions, initiating signalling. HER2-CAR clustering, accompanied by ZAP-70 and LAT recruitment, was enhanced in protrusions. While Lck distribution remained unchanged, exclusion of the phosphatase CD45 was enhanced at protrusion-cell contacts, independently of the CAR signalling domain. Overall, signalling machinery rearranged faster and more effectively at protrusive contacts than at main plasma membrane regions. Together, our data re-frame protrusions as sites of enhanced receptor activation by exclusion and clustering dynamics rather than by pre-enrichment of the signalling machinery.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"135 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147731427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we establish an ex vivo culture system that faithfully recapitulates in vivo development and enables long-term live imaging of mouse fetal ovaries. Using high resolution imaging, we capture the dynamic behaviors of germ cells during the development from oogonia to nascent oocytes. We identify pronounced blebbing activity during the mitosis-to-meiosis transition. This behavior is regulated by meiotic initiation signals, underscoring its potential developmental relevance, although its precise role remains unclear. A prevailing model suggests that oocyte formation involves organelle transfer from neighboring germ cells during cyst breakdown. However, through photoconversion-based tracking, we observe no detectable transfer of mitochondria or centrosomes, as organelles remain confined to individual cells. These findings point to alternative mechanisms for cytoplasmic enrichment in oocytes. Our study provides new insights into mammalian oocyte formation and establishes a powerful platform for analyzing germ cell dynamics in real time.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147731381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is localized in a membrane nanocluster harboring the B-cell antigen receptor of IgD class (IgD-BCR), where it functions to maintain the resting state of naïve B-lymphocytes. How CD20 exerts this resting B-cell gatekeeper function is not yet known. Using Ramos and human peripheral blood B-cells, we show here that the serine/threonine kinase PKCδ constitutively phosphorylates serine residues in the two cytosolic tails of CD20. Phosphorylated CD20 becomes a binding target for 14-3-3 adaptor proteins, which link it to the RhoA GDP/GTP exchange factor GEF-H1 and the microtubule network, supporting the function of the IgD-BCR nanocluster. Binding of anti-CD20 antibodies results in microtubule dissociation and replacement of the GEF-H1/CD20 complex with a RhoA-GTP/ROCK1/CD20 complex, which promotes actomyosin contractility. Our study suggests that CD20 not only maintains the resting state of B-lymphocytes by anchoring the microtubule network and controlling the stability of the IgD-BCR nanocluster, but also mediates the microtubule/actin switch in active B-lymphocytes. These findings could have important implications for anti-CD20 antibody treatment and the optimization of therapeutic protocols.","PeriodicalId":501009,"journal":{"name":"The EMBO Journal","volume":"242 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147702132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike previous models, this system supports long-term expansion of newly identified human-specific alveolar progenitor cells and serum-free differentiation into alveolar type 1 (AT1)-like cells. Using this platform, we find that interferon-gamma (IFN-γ) exerts cytotoxic effects on mature AT1-like cells while promoting survival of alveolar progenitor cells mediated by BIRC3. This unexpected selective positive effect of IFN-γ on alveolar progenitors underscores the need for nuanced and context-dependent evaluation of the influence of pro-inflammatory cytokines on alveolar regeneration.

To assess how CIN might affect EV-mediated signalling in TNBC, we studied the EV landscape of TNBC cell lines with induced CIN. We find that CIN leads to increased secretion of EVs and that these EVs promote cell migration of recipient cells. EVs are enriched for extracellular matrix (ECM) proteins, including EFEMP1. Indeed, modulation of EFEMP1 levels in EVs significantly alters migration behaviour of EV-treated cells. We show that EFEMP1 expression is regulated by STAT1, that EVs from STAT1-deficient cells no longer promote migration, and that this can be rescued by overexpression of EFEMP1 in STAT1-null cells. Xenografting TNBC cells with EFEMP1-enriched cells promotes migration in zebrafish embryos, suggesting that EFEMP1 expression is a factor that promotes metastasis.
