Here, we characterize Kiwa, a widespread two-component system composed of the transmembrane sensor KwaA and the DNA-binding effector KwaB. Cryogenic electron microscopy (cryo-EM) analysis reveals that KwaA and KwaB assemble into a large, membrane-associated supercomplex. Upon phage binding, KwaA senses infection at the membrane, leading to KwaB binding of ejected phage DNA and inhibition of replication and late transcription, without inducing host cell death. Although KwaB can bind DNA independently, its antiviral activity requires association with KwaA, suggesting spatial or conformational regulation. We show that the phage-encoded DNA-mimic protein Gam directly binds and inhibits KwaB but that co-expression with the Gam-targeted RecBCD system restores protection by Kiwa. Our findings support a model in which Kiwa coordinates membrane-associated detection of phage infection with downstream DNA binding by its effector, forming a spatially coordinated antiviral mechanism.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"9 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144715436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While recent single-cell and spatial multi-omics technologies quantify individual cell characteristics, predicting their evolution requires mathematical modeling.

This enables systematic integration of biological knowledge and multi-omics data to generate <em>in silico</em> models, enabling virtual “thought experiments” that test and expand our understanding of multicellular systems and generate new testable hypotheses. This paper motivates and describes the grammar, offers a reference implementation, and demonstrates its use in developing both <em>de novo</em> mechanistic models and those informed by multi-omics data. We show its potential through examples in cancer and its broader applicability in simulating brain development. This approach bridges biological, clinical, and systems biology research for mathematical modeling at scale, allowing the community to predict emergent multicellular behavior.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"720 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a comprehensive proteomic and histological analysis of 516 samples from 13 human tissues spanning five decades. This dynamic atlas reveals widespread transcriptome-proteome decoupling and proteostasis decline, characterized by amyloid accumulation. Based on aging-associated protein changes, we developed tissue-specific proteomic age clocks and characterized organ-level aging trajectories. Temporal analysis revealed an aging inflection around age 50, with blood vessels being a tissue that ages early and is markedly susceptible to aging. We further defined a plasma proteomic signature of aging that matches its tissue origins and identified candidate senoproteins, including GAS6, driving vascular and systemic aging. Together, our findings lay the groundwork for a systems-level understanding of human aging through the lens of proteins.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"25 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arachnoid cuff exit (ACE) points, anatomical discontinuities in the arachnoid mater around bridging veins, serve as key sites of CSF-dura exchange. Here, we show that dural mast cells regulate CSF dynamics at ACE points. Upon degranulation, mast cells release histamine, inducing vasodilation of bridging veins and reducing perivascular spaces critical for CSF drainage. During bacterial meningitis, pathogens exploit ACE points to access the brain. However, mast cell activation redirects CSF flow, recruits neutrophils, and limits bacterial invasion. Mice lacking dural mast cells exhibit impaired immune responses and higher brain bacterial loads. These findings reveal dural mast cells as central players in modulating CSF flow and meningeal immunity. Targeting mast cells or their mediators may enhance CNS clearance and defense mechanisms, offering a potential therapeutic avenue for brain infections.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"115 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insults, including ischemic stroke, can disrupt this balance and incite an exaggerated inflammatory response, yet the underlying mechanism remains unclear. Here, we show that the mast-cell-specific receptor Mrgprb2 regulates post-stroke brain inflammation from the meninges. Mrgprb2 causes meningeal mast cell degranulation after stroke, releasing immune mediators. This process recruits skull bone marrow neutrophils into the dura and further promotes neutrophil migration from the dura into the brain by cleaving the chemorepellent semaphorin 3a. We demonstrate that the human ortholog, MRGPRX2, is expressed in human meningeal mast cells and is activated by upregulation of the neuropeptide substance P following stroke. Pharmacologically inhibiting Mrgprb2 reduces post-stroke inflammation and improves neurological outcomes in mice, providing a druggable target. Collectively, our study identifies Mrgprb2 as a critical meningeal gatekeeper for immune migration from skull bone marrow reservoirs into the brain.","PeriodicalId":9656,"journal":{"name":"Cell","volume":"53 1","pages":""},"PeriodicalIF":64.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A buildup of squalene within intestinal epithelial cells creates a reducing environment, making more reduced glutathione available for parasite uptake.

Here, we report that structural variations in symbiotic lipid A lead to divergent immune responses with each lipid A structure, eliciting effects distinct from those induced by classical lipid A. Certain lipid A structures can induce a sustained interferon (IFN)-β response orchestrated by Cdc42-facilitated Toll-like receptor 4 (TLR4) endocytosis and lipid droplet (LD) formation. This lipid A-directed IFN-β response is paramount for colon RORγt<sup>+</sup> regulatory T cell (Treg) induction while simultaneously suppressing colonic T<sub>H</sub>17 cells and controlling gut inflammation. Intriguingly, the quantitatively dominant penta-acylated lipid A species in Bacteroidetes fails to elicit an IFN-β response.
