Abstract
BACKGROUND Microvesicles (MVs) play a crucial role in bronchopulmonary dysplasia (BPD). There are many MVs in circulating plasma, and they are in direct contact with lung endothelial cells. However, the molecular mechanism and causative effect of circulating MVs on BPD remain unclear. METHODS Clinical plasma samples were collected, circulating MVs were isolated, and microRNA (miRNA) sequencing was performed. The BPD model was established, and different MVs were administered. Alveoli and pulmonary vessels were examined by hematoxylin-eosin staining, and body weight and length were measured. In vitro, gene expression was disrupted by miRNA mimics, miRNA inhibitors or plasmid transfection. Cell proliferation and protein expression were detected by cell scratch assay, accurate 5-ethynyl-2-deoxyuridine test, western blotting, or immunofluorescence assay. RESULTS BPD-derived MVs further aggravated pulmonary vascular simplification, while circulating MVs from control mice mitigated pulmonary vascular simplification. Micro-RNA sequencing and independent sample verification revealed that miR139-3p, but not miR6125 or miR193b-3p, was the most critical effector molecule in MVs. Mechanism studies showed that eukaryotic translation initiation factor 4E binding protein 1 was the target gene for miR139-3p. In addition, we found that supplementation of miR139-3p inhibitor partially alleviated pulmonary vascular simplification. CONCLUSIONS These results indicate that circulating MVs are involved in forming BPD by carrying miR139-3p molecules and support miR139-3p inhibitors as a potential therapeutic strategy for alleviating pulmonary vascular simplification in BPD.

Abstract
Increased life expectancy is usually associated with comorbidities, such as cardio and cerebrovascular disease causing impaired functionality. A common underlying cause of these comorbidities is vascular inflammation and injury. Elevated levels of circulating microvesicles (cMV), as a product of a hemostatic and inflammatory cell activation, could be direct mapping of an imbalanced hemostasis. In this manuscript, we aimed to investigate by liquid biopsy whether successful aging can be discriminated by cMV levels and phenotype. To this purpose, we included 135 community-dwelling octogenarians in a cross-sectional study. Successful aging was defined as good functional (Barthel Index > 90 points, and Lawton index score > 7/4 points for women and men, respectively) and cognitive status (Spanish version of the Mini-Mental State Examination -MEC- > 24 points) and no need for institutionalization. Total, annexin V positive (AV+), and AV– cMV from different cell origins from the vascular compartment were phenotypically characterized and quantified from fasting plasma samples by flow cytometry. Successful aging was associated with lower plasma concentrations of total and AV+ CD141+/CD41+-CD61+, and PAC1+/AV+, CD141+/AV+, and CD36+/AV– cMV. From these phenotypes, ROC curve analyses revealed that CD141+/AV+ and CD141+/CD41+-CD61+/AV+ endothelial- and platelet-derived cMV discriminate successful and non-successful aging with an AUC (95%CI) of 0.655 (0.551, 0.758), P = 0.005, and 0.638 (0.535, 0.741), P = 0.013, respectively. In conclusion, successful aging is associated with low levels of cMV released by endothelial cells and platelets, indicating lower endothelial cell inflammation and platelet activation. Our results contribute to the understanding of the link between unsuccessful aging, cognitive decline and vascular cell inflammatory disturbances.

Abstract
The authors hypothesized that the cytokine storm described in COVID-19 patients may lead to consistent cell-based tissue factor (TF)-mediated activation of coagulation, procoagulant microvesicles (MVs) release, and massive platelet activation. COVID-19 patients have higher levels of TF+ platelets, TF+ granulocytes, and TF+ MVs than healthy subjects and coronary artery disease patients. Plasma MV-associated thrombin generation is present in prophylactic anticoagulated patients. A sustained platelet activation in terms of P-selectin expression and platelet-leukocyte aggregate formation, and altered nitric oxide/prostacyclin synthesis are also observed. COVID-19 plasma, added to the blood of healthy subjects, induces platelet activation similar to that observed in vivo. This effect was blunted by pre-incubation with tocilizumab, aspirin, or a P2Y12 inhibitor.

Abstract
BACKGROUND Graft patency is one of the major determinants of long-term outcome following coronary artery bypass graft surgery (CABG). Biomarkers, if indicative of the underlying pathophysiological mechanisms, would suggest strategies to limit graft failure. The prognostic value of microvesicles (MVs) for midterm graft patency has never been tested. OBJECTIVES The aim of this study was to evaluate whether MV pre-operative signature (number, cellular origin, procoagulant phenotype) could predict midterm graft failure and to investigate potential functional role of MVs in graft occlusion. METHODS This was a nested case-control substudy of the CAGE (CoronAry bypass grafting: factors related to late events and Graft patency) study that enrolled 330 patients undergoing elective CABG. Of these, 179 underwent coronary computed tomography angiography 18 months post-surgery showing 24% graft occlusion. Flow cytometry MV analysis was performed in 60 patients (30 per group with occluded [cases] and patent [control subjects] grafts) on plasma samples collected the day before surgery and at follow-up. RESULTS Before surgery, cases had 2- and 4-fold more activated platelet-derived and tissue-factor positive MVs respectively than control subjects. The MV procoagulant capacity was also significantly greater. Altogether this MV signature properly classified graft occlusion (area under the curve 0.897 [95% confidence interval: 0.81 to 0.98]; p < 0.0001). By using an MV score (0 to 6), the odds ratio for occlusion for a score above 3 was 16.3 (95% confidence interval: 4.1 to 65.3; p < 0.0001). CONCLUSIONS The pre-operative signature of MVs is independently associated with midterm graft occlusion in CABG patients and a cumulative MV score stratifies patients' risk. Because the MV signature mirrors platelet activation, patients with a high MV score could benefit from a personalized antiplatelet therapy.

Abstract
Circulating microvesicles (cMV) are small phospholipid-rich blebs shed from the membrane of activated vascular cells that contribute to vascular disease progression. We aimed to investigate whether the quality of the Nordic diet is associated with the degree of blood and vascular cell activation measured by MV shedding in elderly patients after an acute myocardial infarction (AMI). One-hundred and seventy-four patients aged 70–82 years were included in this cross-sectional study. Fasting blood samples were taken within 2 to 8 weeks after an AMI. Annexin V (AV)+ cMV derived from blood and vascular cells were measured through flow cytometry. A patient’s usual diet was recorded with the SmartDiet® questionnaire. Patients with higher adherence to the Nordic diet (highest diet score) had lower levels of total AV+ and platelet-derived (CD61+/AV+ and CD31+/AV+) cMV. Dietary habits influence cellular activation. A high adherence to the Nordic diet (assessed by the SmartDiet® score) in elderly post-AMI patients was associated with lower levels of platelet activation, which was reflected by a lesser release of MV carrying platelet-derived epitopes, potentially contributing to an explanation of the cardioprotective effects of the Nordic diet.
