MicroRNA (miR)-92a is enriched in endothelial cells (ECs) and circulation under atheroprone conditions. Macrophages are the primary immune cells in atherosclerotic lesions that modulate lesion development. Therefore, we hypothesize that, in response to atheroprone stimuli, ECs export miR-92a to macrophages to regulate their functions and enhance atherosclerotic progression. Approach and Results: We investigated the macrophage functions that are regulated by EC miR-92a under atheroprone microenvironments. We first determined the distributions of functional extracellular miR-92a by fractionating the intravesicular and extravesicular compartments from endothelial conditioned media and mice serum. The results indicate that extracellular vesicles are the primary vehicles for EC miR-92a transportation. Overexpression of miR-92a in ECs enhanced the proinflammatory responses and low-density lipoprotein uptake, while impaired the migration, of cocultured macrophage. Opposite effects were found in macrophages cocultured with ECs with miR-92a knockdown. Further analyses demonstrated that intravesicular miR-92a suppressed the expression of target gene Krüppel-like factor 4 (KLF4) in macrophages, suggesting a mechanism by which intravesicular miR-92a regulates recipient cell functions. Indeed, the overexpression of KLF4 rescued the EC miR-92a-induced macrophage atheroprone phenotypes. Furthermore, an inverse correlation of intravesicular miR-92a in blood serum and KLF4 expression in lesions was observed in atherosclerotic animals, indicating the potential function of extracellular miR-92a in regulating vascular diseases.\u0000\u0000\u0000CONCLUSIONS\u0000EC miR-92a can be transported to macrophages through extracellular vesicles to regulate KLF4 levels, thus leading to the atheroprone phenotypes of macrophage and, hence, atherosclerotic lesion formation.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90079031","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}

Indeed, excessive production of paracrine factors from damaged EC promotes the recruitment of circulating inflammatory cells and triggers vascular remodeling through stimulation of pulmonary artery (PA) smooth muscle cell (SMC) contraction and proliferation. Although endothelium injury is recognized to play a causative role in the development and progression of PH, the underlying mechanisms as well as the nature of the signaling molecules that mediates crosstalk between PAECs and adjacent SMCs remain poorly understood.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78465674","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 normal conditions, EV crosstalk is important for proper cell and organ function, but in diseased conditions EV cargos can be altered in a way that promotes disease pathology. Multiple cargos have been observed in EVs, including RNAs, such as microRNA, DNA, proteins, and lipids, which can be encased within EVs or associated with EV membranes. Given this critical function, identifying the communication roles of EVs in normal physiology and diseasedriving mechanisms holds great therapeutic promise. In this issue of Arteriosclerosis, Thrombosis, and Vascular Biology, Chang et al3 propose EV transport as a major pathway in which miR-92a is transported from endothelial cells to macrophages that, in turn, contributes to the development of atherosclerosis. This study identifies a key mechanism of how miR-92a cell-cell communication occurs in atherosclerotic vasculature and raises the potential of EV-associated miR-92a as a disease biomarker and therapeutic target.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80596177","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 contrast, the role of FXI in hemostasis is rather small, especially compared with FIX deficiency. Little is known about the cause of the difference in phenotypes associated with FIX deficiency and FXI deficiency. We speculated that activation of FIX via the intrinsic coagulation is not solely dependent on FXI(a; activated FXI) and aimed at identifying an FXI-independent FIX activation pathway. Approach and Results: We observed that ellagic acid and long-chain polyphosphates activated the coagulation system in FXI-deficient plasma, as could be demonstrated by measurement of thrombin generation, FIXa-AT (antithrombin), and FXa-AT complex levels, suggesting an FXI bypass route of FIX activation. Addition of a specific PKa (plasma kallikrein) inhibitor to FXI-deficient plasma decreased thrombin generation, prolonged activated partial thromboplastin time, and diminished FIXa-AT and FXa-AT complex formation, indicating that PKa plays a role in the FXI bypass route of FIX activation. In addition, FIXa-AT complex formation was significantly increased in F11-/- mice treated with ellagic acid or long-chain polyphosphates compared with controls and this increase was significantly reduced by inhibition of PKa.\u0000\u0000\u0000CONCLUSIONS\u0000We demonstrated that activation of FXII leads to thrombin generation via FIX activation by PKa in the absence of FXI. These findings may, in part, explain the different phenotypes associated with FIX and FXI deficiencies.","PeriodicalId":8404,"journal":{"name":"Arteriosclerosis, Thrombosis, & Vascular Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90594859","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}
