Summary: Endothelial activation and sickle red blood cell (RBC) adhesion play crucial roles in sickle cell disease (SCD). Sickle RBC-derived extracellular vesicles (REVs) are more abundant and promote endothelial cell (EC) activation. In this study, SS REVs were found to induce acute microvascular EC activation and abnormal RBC adhesion in 2 hours. The adhesion was reduced by haemopexin or ADAMTS13 and was higher in SS RBCs from patients with markers of haemolysis or deep vein thrombosis. These findings highlight the significant contribution of REVs to the pathophysiology of SCD and provide insights for potential treatment strategies targeting VWF.

Summary: Coagulopathy in COVID-19 patients is caused by systemic hypercoagulation and inflammation. Endothelial dysfunction leads to the release of tissue factor and von Willebrand factor, resulting in prothrombinase activation. The vWF/ADAMTS-13 ratio can be used to assess the severity of the disease.

Summary: This study tested and optimized silicon surface functionalization procedures for capturing urinary extracellular vesicles (uEVs), investigating the influence of silane type and protein concentration on binding efficiency, observing changes in the biosensor surface using surface characterization techniques, purifying uEVs by a low-vacuum filtration method and concentrating them by ultracentrifugation, and determining physical parameters of uEVs post-isolation. Results showed gradual growth of the molecular layer after modification stages, with no significant changes in characteristic peaks of amino acids and lipids in positive and negative polarization. The optimal concentration of lactadherin protein for the tested system was found to be 25 μg/mL.

Summary: This study identified individuals with persistently low and high von Willebrand factor (VWF) antigen levels in the Atherosclerosis Risk in Community study over a 10-year period, and quantified longitudinal changes in VWF biological activities and cleavage. The results showed that VWF antigen levels increase with aging and there is a functional coordination between VWF and the rate of its cleavage by ADAMTS-13.

Summary: This study found that decreased ADAMTS-13 levels and an imbalance in the VWF/ADAMTS-13 ratio were associated with an increased risk of future venous thromboembolism, suggesting the involvement of the VWF-ADAMTS-13 axis in the pathogenesis of VTE.

Summary: Pre-eclampsia is a hypertensive disease of pregnancy with mechanisms centered around abnormal placentation, inadequate spiral-artery remodeling, and deficiency in trophoblast invasion. Extracellular vesicles (EVs) are suggested to play a crucial role in pre-eclampsia, potentially influencing immune responses, inflammation, altered angiogenesis, and endothelial dysfunction.

Summary: This study aimed to predict the occurrence of non-tumoral portal vein thrombosis (PVT) in patients with compensated cirrhosis by evaluating clinical, biochemical, and hemostatic factors. The results indicated that an ADAMTS-13/VWF ratio < 0.4 could be a reliable predictive biomarker for PVT development.

Summary: When endothelial cells are stimulated by proinflammatory mediators, they release large von Willebrand factor multimers that are not adequately cleaved by ADAMTS-13, resulting in the accumulation of these multimers in the circulation and on inflamed endothelium. This moderate deficiency of ADAMTS-13 under conditions of systemic inflammation may lead to thrombotic complications, which contribute to tissue injury and organ failure associated with severe infections. In this study, we found that recombinant ADAMTS-13 improved survival and reduced thrombotic vascular occlusion in mice with endotoxemia, suggesting that ADAMTS-13 can improve the outcomes of inflammation induced by endotoxemia.

Summary: PE is a common pregnancy disorder characterized by hypertension and proteinuria, with aberrant expression of HLA-DR in STBEVs specifically associated with PE. Further studies are needed to define the role of abnormal placental HLA-DR expression in PE pathogenesis and evaluate the potential application of detecting circulating HLA-DR positive STBEVs in diagnosing and predicting PE in early and mid-pregnancy.

Summary: The knockdown of Ptpn1 in macrophages leads to the enrichment of lactadherin in the small extracellular vesicles (sEVs), which promotes macrophage M2 polarization and enhances intestinal barrier integrity. The communication between macrophages and intestinal epithelial cells (IECs) mediated by lactadherin-enriched sEVs has a protective effect in intestinal inflammation.

Summary: Blood coagulation is a complex physiological process involving the activation of coagulation factors and intercellular communication. Imbalance in coagulation can lead to bleeding or thrombosis, and extracellular vesicles (EVs) may represent valuable approaches for the treatment and diagnosis of thrombotic diseases.

Summary: Factors such as subarachnoid hemorrhage, lesion size, morphology, extent of hemosiderin involvement, and motor dysfunction were identified as independent risk factors affecting the neurological function prognosis in patients with spinal cavernous malformation. Clinically, these factors may be used to identify high-risk patients for worse outcomes and guide treatment decisions based on individual risk factors and symptoms.

Summary: Severe traumatic brain injury can lead to a hypercoagulable state and consumptive coagulopathy. Targeting anionic phospholipid-expressing extracellular vesicles (EVs) with anticoagulation can prevent TBI-induced coagulopathy and improve outcomes.

Summary: The percentage of monocytes in peripheral blood may be a convenient and effective indicator for predicting the outcome of CSDH in patients receiving conservative treatment. Patients with good outcomes had obviously lower circulating monocyte percentages in their peripheral blood counts throughout the treatment period, and the monocyte percentage was also significantly decreased in patients who responded well to atorvastatin combined with dexamethasone.

Summary: Traumatic brain injury (TBI) can lead to neuroinflammation, which is associated with poor outcomes and high mortality in patients. Cellular microvesicles, especially extracellular mitochondria, released from injured cells contribute to TBI-induced coagulopathy and inflammation. In addition to their procoagulant activity, extracellular mitochondria can also induce pro-inflammatory polarization of microglia, aggravating neuroinflammation and cerebral edema in a ROS-dependent manner.

Summary: Transcription factors bind to gene promoter or regulatory sequences to regulate transcription rate. They are also found in anucleated platelets. Several transcription factors, including RUNX1, GATA1, STAT3, NF kappa B, and PPAR, have been reported to play important roles in platelet hyper-reactivity, thrombosis, and atherosclerosis. These activities are independent of gene transcription or protein synthesis, but their exact mechanisms of action are still unclear. This review summarizes recent developments in the study of transcription factors in platelet generation, reactivity, and production of microvesicles, with a focus on their non-transcriptional activities.

Summary: Traumatic brain injury (TBI) can have negative effects on systemic organs, leading to increased mortality and disability. Our study found that brain-derived extracellular vesicles (BDEVs) released from the injured brain can induce widespread fibrin deposition in the microvasculature of the lungs, kidney, and heart, causing histological damage and dysfunction in these organs. Additionally, BDEVs can also induce cell apoptosis and endothelial cell damage in multiple organs.

Summary: In this study, it was found that combined treatment with atorvastatin and dexamethasone in an optimized rat model could effectively promote the absorption of chronic subdural hematoma, decrease inflammatory activity, improve neural functional prognosis, and reduce mortality. The combination treatment was more effective in increasing Kruppelle-like factor 2 and ZO-1 expression, attenuating NF-kappa b expression, and enhancing angiogenic activities, leading to improved outcomes in rats with chronic subdural hematoma compared to single treatments.
