About this Research Topic

Background

This is a Research Topic initiated by NAVBO, the North American Vascular Biology Organization.

Extracellular vesicles (EV) are small, membranous entities released by a variety of cell types to participate in a multitude of physiological and pathophysiological processes within a tissue and in circulation. Their cargo consists of proteins and microRNAs allowing them to interact with both cells and the extracellular matrix. In the cardiovascular system, EVs contribute to both inflammation- and calcification-associated processes. EV-mediated cardiovascular calcification poses a crucial mechanism in the onset and progression of atherosclerosis and calcific aortic valve disease, functioning as a fuse and a driving force for both inflammatory and fibrocalcific responses. Recent discoveries spurred by the rise of multi-omics have led to a more profound understanding of the molecular mechanisms of calcifying EV formation and release by vascular/valvular wall cells, endothelial cells and inflammatory cells. Herein, EVs assume a dual role as ignition foci of calcification and as intercellular communicators to induce a pro-inflammatory and/or pro-osteogenic phenotype.

Despite recent advancements in vesicle biology in the context of cardiovascular pathologies, current therapeutic regimen in atherosclerotic and calcific valve disease are still devoid of causative strategies to prevent the onset or inhibit progression of calcification and inflammation. Furthermore, current imaging modalities fall short of detecting early, subclinical calcification in vivo, delaying diagnosis and therapy of already progressing pathological processes. We aim to gain a full understanding of the mechanisms driving EV-mediated formation of microcalcification, its progression to macrocalcification, and the concomitant EV-induced inflammatory response in cardiovascular tissues. For this purpose, our work is intended to further divulge the role of EVs in genesis and growth of calcification and the tissue inflammatory response. Groundbreaking advances in imaging modalities, multi-omics, systems biology, data science and more are necessary to unveil the mechanisms and regulatory pathways involved in the intricate balance of EV-mediated inflammation and the formation of macro- or microcalcification controlling structural stability of cardiovascular tissues. The research topic editors pioneered the paradigm of an EV-centered approach in the pathophysiology of cardiovascular calcification and inflammation, thereby striving to identify EV-bound molecular targets for a potential new generation of drug therapies to combat cardiovascular disease.

Themes we would like authors to address include, but are not limited to:
1) Experimental studies on the regulatory mechanisms of extracellular vesicle release in the context of atherosclerosis/valve disease/heart failure.
2) Discovery of EV-bound targets of intercellular communication, mediators inducing/inhibiting osteogenic differentiation/proinflammatory phenotype.
3) Studies involving EVs released by monocytes/macrophages, the role of EVs in the cardiovascular inflammatory response.
4) Multi-omics: secretomics, vesicle-omics of different cell populations and disease models.
5) Translational studies on circulating EVs, EV-bound blood biomarkers in health and disease states.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
