Among these, 'synthetic' SMCs-defined by migration, proliferation and extracellular matrix production-accumulate in atherosclerotic lesions and contribute to fibrous cap formation. The mechanisms driving this synthetic transition remain unclear. Here we identify PRDM16, a gene linked to cardiovascular disease, as a critical transcriptional repressor of the synthetic SMC phenotype. PRDM16 expression declined during SMC modulation, and its deletion in mice induced a synthetic program across all SMC subtypes even without pathological stimuli. Under atherogenic conditions, PRDM16 deficiency resulted in the formation of fibroproliferative plaques with more synthetic SMCs and fewer foam cells. Conversely, enforced PRDM16 expression suppressed SMC migration, proliferation and fibrosis. Mechanistically, PRDM16 occupied chromatin and suppressed activating marks at synthetic loci. These findings establish PRDM16 as a gatekeeper of SMC fate and reveal its role in shaping atherosclerotic plaque composition.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":" ","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314214","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}

However, therapeutic application of EC transplantation requires scalable expansion of engraftable ECs that sustain their angiogenic and angiocrine functions. Here we identify a non-canonical aryl hydrocarbon receptor (AHR) pathway switched on by canonical AHR inhibitors that reactivates quiescent EC proliferation. Incubation of tissue-specific human ECs with AHR inhibitors, such as StemRegenin1 (SR1), increased EC proliferation by three-fold within an 8-day period. AHR inhibitors induced 100-fold greater expansion of 200,000 primary human adipose ECs to 2.4 × 1012 ECs, retaining in vivo vessel-forming and homeostatic functions in the recipient mice. AHR inhibitors induce a non-canonical AHR pathway by ornithine decarboxylase 1 (ODC1)-dependent synthesis of polyamines that drives EC cell cycle progression, detoxification of reactive oxygen species and oxidative phosphorylation metabolism, thereby recruiting hibernating ECs to accompany expanding EC populations without imposing replicative senescence. Therefore, AHR inhibitors, through transcriptional-independent protein–protein interactions, shepherd unrestricted human-scalable functional EC expansion, enabling cell therapies. Lin, Geng and colleagues identify a non-canonical AHR pathway that is activated by canonical AHR inhibitors, promoting the proliferation of quiescent endothelial cells with potential applications in cell therapy.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"4 10","pages":"1329-1344"},"PeriodicalIF":10.8,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290307","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}

Mutations in LMNA, which encodes lamin A/C, weaken the nuclear lamina, leading to nuclear damage and muscle disease. Disrupting the linker of nucleoskeleton and cytoskeleton (LINC) complex, which connects the cytoskeleton to the nucleus, may ameliorate LMNA-associated cardiomyopathy, yet the cardioprotective mechanism remains unclear. Here we developed an assay to quantify the coupling between cardiomyocyte contraction and nuclear deformation and interrogate its dependence on the nuclear lamina and LINC complex. The LINC complex was mostly dispensable for transferring contractile strain to the nucleus, and its disruption did not rescue elevated nuclear strain in lamin A/C-deficient cardiomyocytes. Instead, LINC complex disruption eliminated the microtubule cage encircling the nucleus. Microtubule disruption prevented nuclear damage and preserved cardiac function in lamin A/C deficiency. Computational modeling revealed that microtubule forces create local stress concentrations that damage lamin A/C-deficient nuclei. These findings identify microtubule-dependent force transmission as a pathological driver and therapeutic target for LMNA cardiomyopathy.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":" ","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145276848","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 describe that combining the typical risk factors of atrial fibrillation (hypertension, obesity and mitral valve regurgitation (HOMER)) activates adaptive immunity in wild-type mice, ultimately causing electrical remodeling of cardiomyocytes. In HOMER mice, dendritic cells expanded in the left atria and heart-draining lymph nodes, where we detected cardiomyocyte-derived proteins. Systemically expanding B cells, while exposed to interferon-α, produced autoantibodies that disrupted calcium handling in cardiomyocytes. Depleting B cells by using μMT HOMER mice or plasma cells by using Mb1cre/+ Prdm1fl/fl HOMER mice reduced atrial fibrillation while mitigating the prolonged action potential duration we observed in the left atria of HOMER mice. CD20 antibody B cell depletion, a clinical tool in treating lymphoma and autoimmune disease, reduced atrial fibrillation fivefold in HOMER mice. Targeting humoral immunity may provide therapeutic avenues for patients with autoantibody-induced atrial fibrillation. Yamazoe et al. show that B cell-derived autoantibodies contribute to the development of atrial fibrillation, suggesting that targeting the humoral immune response may represent a viable therapeutic approach.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"4 10","pages":"1381-1396"},"PeriodicalIF":10.8,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44161-025-00724-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145253960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identified 122 candidate variants with enhancer activity and allelic imbalance, including 23 variants showing condition-biased and 41 showing sex-biased effects. Integrating lentiMPRA with CUT&RUN epigenome profiling and expression quantitative trait loci data, we prioritized 49 functionally relevant variants.

Here we show that PD-1+ T cells from murine atherosclerotic aortas mainly display a progenitor exhausted phenotype (PD-1intSlamf6+Tim3−), produce IFNγ in vivo, exhibit signs of recent proliferation and maintain polyfunctionality. PD-1 blockade induced marked changes in plaque immune phenotype, with increased PD-1high T cell accumulation, IFNγ production, formation of lymphocyte foci and neutrophil recruitment. Depletion of PD-1high T cells prior to PD-1 blockade did not impede T cell recruitment, suggesting a role for progenitor exhausted PD-1int T cells in ICI-driven T cell plaque accumulation.
