    Abstract Endothelialized in vitro models for cardiovascular disease have contributed greatly to our current understanding of the complex molecular mechanisms underlying thrombosis. To further elucidate these mechanisms, it is important to consider which fundamental aspects to incorporate into an in vitro model. In this review, we will focus on the design of in vitro endothelialized models of thrombosis. Expanding our understanding of the relation and interplay between the different pathways involved will rely in part on complex models that incorporate endothelial cells, blood, the extracellular matrix, and flow. Importantly, the use of tissue-specific endothelial cells will help in understanding the heterogeneity in thrombotic responses between different vascular beds. The dynamic and complex responses of endothelial cells to different shear rates underlines the importance of incorporating appropriate shear in in vitro models. Alterations in vascular extracellular matrix composition, availability of bioactive molecules, and gradients in concentration and composition of these molecules can all regulate the function of both endothelial cells and perivascular cells. Factors modulating these elements in in vitro models should therefore be considered carefully depending on the research question at hand. As the complexity of in vitro models increases, so can the variability. A bottom-up approach to designing such models will remain an important tool for researchers studying thrombosis. As new techniques are continuously being developed and new pathways are brought to light, research question-dependent considerations will have to be made regarding what aspects of thrombosis to include in in vitro models.

    Abstract Cerebral small vessel disease (cSVD) accounts for 25% of ischemic strokes and is a major cause of cognitive decline. Inflammatory processes, involving immune cells and platelets might drive development and progression of cSVD. The aim of the study was to identify potential novel biomarkers for cSVD, gaining new insights into its pathophysiology. We measured inflammation and platelet and neutrophil activation markers in patients with cSVD and age-matched controls. It was hypothesized that cSVD is accompanied by altered levels of these markers. The levels of interleukin 1β, CX

    Abstract Background: Bruton's kinase (Btk) is critical for collagen-triggered platelet signal transduction. The Btk inhibitor ibrutinib has been shown to selectively block platelet adhesion to atherosclerotic plaque material under laminar arterial flow. However, this has not been studied under a shear gradient, which is characteristic for atherothrombosis.
    Objective: To determine the effect of ibrutinib treatment on in vitro thrombus formation on collagen and atherosclerotic plaque material in the absence or presence of a shear gradient.
    Methods: Blood was obtained from patients with chronic lymphocytic leukemia, mantle-cell lymphoma and Waldenström macroglobulinemia with and without ibrutinib treatment and perfused through a microfluidic channel with(out) 60% stenosis over Horm type I collagen or human atherosclerotic plaque homogenate.
    Results: At a constant shear rate of 1500 s
    Conclusion: Treatment of patients with haematological disorders with the Btk inhibitor ibrutinib reduces in vitro platelet deposition, thrombus size and contraction on human atherosclerotic plaque around a stenosis when compared to patients not receiving ibrutinib.

    Abstract Background: Platelets and neutrophils are the first blood cells accumulating at sites of arterial thrombus formation, and both cell types contribute to the pathology of thrombotic events. We aimed to identify key interaction mechanisms between these cells using microfluidic approaches.
    Methods: Whole-blood perfusion was performed over a collagen surface at arterial shear rate. Platelet and leukocyte (in majority neutrophil) activation were microscopically visualized using fluorescent markers. The contributions of platelet-adhesive receptors (integrin, P-selectin, CD40L) and chemokines were studied by using inhibitors or antibodies and using blood from patients with GT (Glanzmann thrombasthenia) lacking platelet-expressed αIIbβ3.
    Results: We observed (1) an unknown role of activated platelet integrin αIIbß3 preventing leukocyte adhesion, which was overcome by short-term flow disturbance provoking massive adhesion; (2) that platelet-expressed CD40L controls the crawling pattern and thrombus fidelity of the cells on a thrombus; (3) that continued secretion of platelet substances promotes activation of identified neutrophils, as assessed by (fMLP [
    Conclusions: Together, these findings reveal a multifaceted regulation of adhesion and activation of neutrophils by platelets in a thrombus, with a balanced role of several platelet-adhesive receptors and a promoting role of platelet-released substances. This multivalent nature of neutrophil-thrombus interactions offers novel prospects for pharmacological intervention.

    Abstract Introduction: Studying arterial thrombus formation by
    Methods: A homogenate of human atherosclerotic plaques was coated on glass coverslips by conventional manual droplet coating or by spin coating. Prior to coating, a subset of coverslips was plasma treated. Water contact angle measurements were performed as an indicator for the hydrophilicity of the coverslips. Homogeneity of plaque coatings was determined using profilometric analysis and scanning electron microscopy. Thrombogenicity of the plaque material was assessed in real time by microscopic imaging while perfusing whole blood at a shear rate of 1500 s
    Results: Plasma treatment of glass coverslips, prior to spin coating with plaque material, increased the hydrophilicity of the coverslip compared to no plasma treatment. The most homogeneous plaque coating and highest platelet adhesion was obtained upon plasma treatment followed by spin coating of the plaque material. Manual plaque coating on non-plasma treated coverslips yielded lowest coating homogeneity and platelet adhesion and activation.
    Conclusion: Spin coating of atherosclerotic plaque material on plasma treated coverslips leads to a more homogenous coating and improved platelet adhesion to the plaque when compared to conventional droplet coating on non-plasma treated coverslips. These properties are beneficial in ensuring the quality and reproducibility of flow experiments.

    Abstract Objective: platelets possess not only haemostatic but also inflammatory properties, which combined are thought to play a detrimental role in thromboinflammatory diseases such as acute coronary syndromes and stroke. Phosphodiesterase (PDE) 3 and -5 inhibitors have demonstrated efficacy in secondary prevention of arterial thrombosis, partially mediated by their antiplatelet action. Yet it is unclear whether such inhibitors also affect platelets' inflammatory functions. Here, we aimed to examine the effect of the PDE3A inhibitor cilostazol and the PDE5 inhibitor tadalafil on platelet function in various aspects of thromboinflammation. Approach and results: cilostazol, but not tadalafil, delayed ex vivo platelet-dependent fibrin formation under whole blood flow over type I collagen at 1000 s
    Conclusions: this study demonstrated yet unrecognised roles for platelet PDE3A and platelet PDE5 in platelet procoagulant and proinflammatory responses.

    Abstract The cAMP-protein kinase A (PKA) pathway in platelets is important for both platelet activation and inactivation. We hypothesize that proteins/processes downstream of the cAMP-PKA pathway that are regulated after platelet activation ánd subsequent inactivation can serve as a "switch" in platelet activation and inhibition. We used a STRING-based protein-protein interaction network from proteins of interest distilled from publicly available quantitative platelet proteome datasets. The protein network was integrated with biological pathway information by functional enrichment analysis, phosphorylation by PKA, and drug-target information. Functional enrichment analysis revealed biological processes related to vesicle secretion and cytoskeletal reorganization to be overrepresented among these 30 proteins coinciding with topological clusters in the network. Our method identified proteins/processes with functions related to vesicle transport, cyclin-dependent protein kinases, tight junctions, and small GTPases as potential switches in platelet activation and inhibition. Next to established enzymes in cAMP-PKA signaling, such as PDE3A, proteins with an unknown/less well-known role in platelet biology, such as Stonin-2 and ABLIM-3, emerged from our analysis as interesting candidates for reversal of platelet activation. Our method can be used to repurpose existing datasets and provide a coherent overview of mechanisms involved to predict novel connections, by visually integrating multiple datasets. SIGNIFICANCE: This article presents a novel approach of visually incorporating multiple existing tools and proteomics datasets and in doing so provides novel insight into the complex molecular mechanisms involved in platelet activation. Using our approach, we also highlight several interesting candidates for future research into pathologies with high platelet reactivity.

    Abstract While in recent trials the dual pathway inhibition with aspirin plus rivaroxaban has shown to be efficacious in patients with atherosclerotic cardiovascular disease, little is known about the effects of this combination treatment on thrombus formation and vascular remodelling upon vascular damage. The aim of this study was to examine the effects of aspirin and/or rivaroxaban on injury-induced murine arterial thrombus formation in vivo and in vitro, vessel-wall remodelling, and platelet-leukocyte aggregates. Temporary ligation of the carotid artery of C57BL/6 mice, fed a western type diet, led to endothelial denudation and sub-occlusive thrombus formation. At the site of ligation, the vessel wall stiffened and the intima-media thickened. Aspirin treatment antagonized vascular stiffening and rivaroxaban treatment led to a positive trend towards reduced stiffening. Local intima-media thickening was antagonized by both aspirin or rivaroxaban treatment. Platelet-leukocyte aggregates and the number of platelets per leukocyte were reduced in aspirin and/or rivaroxaban treatment groups. Furthermore, rivaroxaban restricted thrombus growth and height in vitro. In sum, this study shows vascular protective effects of aspirin and rivaroxaban, upon vascular injury of the mouse artery.
