Here, we show the generation of several hand2 mutant alleles in zebrafish and demonstrate that dimerization-deficient mutants display the null phenotype but DNA-binding-deficient mutants do not. Rescue experiments with Hand2 variants using a newly identified hand2 enhancer confirmed these observations. To identify Hand2 effectors critical for cardiogenesis, we analyzed the transcriptomes of hand2 loss- and gain-of-function embryonic cardiomyocytes and tested the function of eight candidate genes in vivo; pdgfra was most effective in rescuing myocardial migration in hand2 mutants. Accordingly, we identified a putative Hand2-binding region in the zebrafish pdgfra locus that is important for its expression. In addition, Hand2 loss- and gain-of-function experiments in mouse embryonic stem cell-derived cardiac cells decreased and increased Pdgfra expression, respectively. Altogether, these results further our mechanistic understanding of HAND2 function during early cardiogenesis. Xu and colleagues show that the transcription factor Hand2 promotes pdgfra expression during early cardiogenesis and that it can do so independently of direct DNA binding by interacting with Tcf3.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"3 12","pages":"1531-1548"},"PeriodicalIF":9.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44161-024-00574-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807170","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}

Among the most common CH mutations, ASXL1 mutations pose the highest risk for cardiovascular diseases (CVDs), yet the mechanisms by which they contribute to CVDs are unclear. Here we show that hematopoietic cells harboring C-terminally truncated ASXL1 mutant (ASXL1-MT) accelerate the development of atherosclerosis in Ldlr–/– mice. Transcriptome analyses of plaque cells showed that monocytes and macrophages expressing ASXL1-MT exhibit inflammatory signatures. Mechanistically, we demonstrate that wild-type ASXL1 has an unexpected non-epigenetic role by suppressing innate immune signaling through the inhibition of IRAK1–TAK1 interaction in the cytoplasm. This regulatory function is lost in ASXL1-MT, resulting in NF-κB activation. Inhibition of IRAK1/4 alleviated atherosclerosis driven by ASXL1-MT and decreased inflammatory monocytes. The present work provides a mechanistic and cellular explanation linking ASXL1 mutations, CH and CVDs. Somatic mutations in ASXL1 lead to clonal hematopoiesis, and Sato et al. elucidate the molecular mechanisms by which mutated ASXL1 in hematopoietic cells drives atherosclerosis in mice.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"3 12","pages":"1568-1583"},"PeriodicalIF":9.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142802472","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}

The inflammatory hypothesis of atherosclerosis has been catapulted to the forefront of cardiovascular research as clinical trials have shown that anti-inflammatory therapy reduces adverse cardiovascular events. However, no current therapies have been specifically designed to target the phenotype of plaque cells. Fate mapping has revealed that plaque cells convert to detrimental and beneficial cell phenotypes during atherosclerosis, with cumulative evidence highlighting that vascular cell plasticity is intimately linked with plaque inflammation, ultimately impacting lesion stability. Here we review vascular cell plasticity during atherosclerosis in the context of the chronic inflammatory plaque microenvironment. We highlight the need to better understand how plaque cells behave during therapeutic intervention. We then propose modulating plaque cell phenotype as an unexplored therapeutic paradigm in the clinical setting. Lin et al. review the phenotypic shifts in vascular smooth muscle and endothelial cells that both drive and result from the chronic inflammation characteristic of atherosclerosis progression. Their review provides insights into potential therapeutic strategies aimed at modulating plaque cell phenotypes to improve clinical outcomes.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"3 12","pages":"1408-1423"},"PeriodicalIF":9.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142803939","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}

We observed that venous endothelial cells proliferate into the adjacent capillary bed upon influenza injury and hyperoxia injury. Imaging analysis demonstrated that venous endothelial cells proliferate and differentiate into general capillary and aerocyte capillary endothelial cells after infection, thus contributing to repair of the capillary plexus vital for gas exchange. Our studies thus establish that venous endothelial cells exhibit demonstrable progenitor capacity upon respiratory viral injury and sterile injury, contributing to repair of the alveolar capillary bed responsible for pulmonary function.

With surgery being the only treatment strategy, understanding the molecular mechanisms of CCM is crucial in finding alternative therapeutic options for CCM. Neutrophil extracellular traps (NETs) were recently reported in CCM, and NETs were shown to have positive or negative effects in different disease contexts. In this study, we investigated the roles of NETs in CCM by pharmacologically inhibiting NET formation using Cl-amidine (a peptidyl arginine deiminase inhibitor). We show here that Cl-amidine treatment reduced lesion burden, coagulation and endothelial-to-mesenchymal transition. Furthermore, NETs promoted the activation of microglia and fibroblasts, leading to increased neuroinflammation and a chronic wound microenvironment in CCM. The inhibition of NET formation caused endothelial quiescence and promoted a healthier microenvironment. Our study suggests the inhibition of NETs as a potential therapeutic strategy in CCM. Onyeogaziri et al. show that the formation of neutrophil extracellular traps contributes to a chronic wound state in cerebral cavernous malformation, while inhibition of these traps with CI-amidine establishes a healthier microenvironment and promotes endothelial cell quiescence, suggesting use of CI-amidine as a potential therapeutic strategy.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"3 12","pages":"1549-1567"},"PeriodicalIF":9.4,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44161-024-00577-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142782025","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}
