Special Issue Information

Dear Colleagues,

Vascular diseases are among the leading causes of morbidity and mortality worldwide, with manifestations ranging from atherosclerosis and aberrant angiogenesis to devastating bleeding and occlusive thrombosis. Platelets are increasingly becoming recognized as essential participants in these pathologies beyond their function as effectors of thrombotic complications, also linking inflammatory and/or infectious disease with vascular complications. With their ability to regulate angiogenesis and tissue homeostasis and their capacity to sense and modulate the inflammatory processes underlying endothelial dysfunction, the contributions of these small, seemingly inconspicuous cells are manifold.

For this Special Issue, we invite authors to submit research articles and reviews focusing on the cellular and molecular mechanisms involved in vascular diseases, highlighting recent findings on the contribution of platelets as regulators and drivers of vascular diseases, their interplay with vascular and immune cells, and/or their potential to act as targets for diagnostic, preventive, and interventive treatment. We welcome clinical studies as well as studies involving cell culture techniques and mouse models with the aim of expanding current knowledge on the versatile roles of platelets in the complex variety of vascular diseases.

We ask authors to submit an abstract prior to article submission to make sure that their work falls within the scope of this Special Issue.

Sincerely, 

Dr. Waltraud C. Schrottmaier

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The pathological conditions caused by blood platelet activation constitute a fundamental core in the pathogenesis of Acute Coronary Syndrome (ACS). The hyperactivity of platelets in ACS is well-documented, but there is still little research into the molecular basis of phenotypic changes in platelet functionality. To expand the knowledge of this phenomenon, we analyzed the disturbances in the expression of several key platelet receptors and the aspect of regulating potential abnormalities. Platelet surface receptors are responsible for maintaining the hemostatic balance, platelet interaction with immune cells, and support of the coagulation cascade leading to occlusion of the vessel lumen. Due to their prominent role, platelet receptors constitute a major target in pharmacological treatment. Our work aimed to identify the molecular alteration of platelet surface receptors, which showed augmented mRNA expression of P2Y12, GP1BB, ITGA2B, and ITGB3 and increased protein concentrations of P2Y12 and GP IIb/IIIa in ACS. The upregulation of the P2Y12 level was also confirmed by confocal and cytometric visualization. Furthermore, we evaluated the expression of two microRNAs: miR-223-3p and miR-126-3p, which were suggested to regulate platelet P2Y12 expression. Results of our study present new insight into the molecular background of ACS. Full article
