Background

This Research Topic is the second volume of the “Effects of Cell Interactions at the Endothelium in Leukocyte Differentiation and Polarization during Inflammation” Community Series. Please see volume I here.

A complex exchange of signals between endothelial cells and tissues occurs during steady-state and in inflammatory conditions. These interactions involve numerous cell types including an active contribution from endothelial cells and occur on both sides of the endothelial monolayer. In addition to functioning as selective permeability barriers, it is increasingly recognized that local cell attraction to endothelial cells provides the potential for focal interactions between relevant cells. In this context, cellular interactions taking place at the surface of the endothelium and within the perivascular spaces are thought to initiate crucial steps in the generation and shaping of immune responses.

Blood elements (such as leukocytes, platelets, and vesicles) converge to the barrier formed by the endothelium where perivascular (such as macrophages, pericytes) initiate, convey, and/or amplify signals revealing tissue status. The innate and adaptative functions of endothelial cells themselves together with the immune functions of assembled cells at a focal point in capillaries create the potential for exchange of signals and dynamic fine tuning of responses through cell programming and cell selection. The resulting immune response may range from inadequate immunity and/or exhaustion to excess tissue destruction and fibrosis. Productive inflammation and its resolution are critically reliant on which cells are recruited and in which order, their state of activation, and interactions between recruited cells.

Tissue-dependent signals further shape the recruitment of leukocytes to the endothelium. In the kidney for instance, in the presence of immune complexes, perivascular resident macrophages located in subendothelial spaces coupled with endothelial cells induce monocyte and neutrophil tissue infiltration, operating therefore as an anatomical and functional unit.

The goals of this Research Topic are (i) to analyze how signal integration and partnering of cell types in transendothelial migration contribute to the development of tissue inflammation and how responses are geared towards specific profiles of reactions to injury; (ii) how the interplay between cell types including, but not limited to, endothelial cells, monocytes, resident macrophages, and T and B cells dynamically governs the immune responses that take place in the tissue; (iii) in which way do integrative capacities of endothelial and subendothelial cells shape and coordinate the successive recruitment of leukocyte populations.

Manuscripts published in this research topic will provide insights into cell interactions at the endothelium in steady-state and in inflammation, in in vitro or in vivo models, and in tissue-specific settings. Although not limited to the following points, we would welcome the submissions of Original Research, Review, Minireview addressing:

- Monocyte (bulk and subsets) activation and polarization in interactions with activated endothelial cells, tissue specificity characteristics, effects of transmigration on the status of monocytes and endothelial cells

- Interactions between monocytes and lymphocytes recruited at the surface of endothelial cells and functional implications

- Contributions of various subendothelial cell types, such as macrophage populations, to the recruitment and activation of leukocytes populations at the surface of endothelial cells

Topic editors

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • Each Research Topic must be approved by the specialty chief editor, and it falls 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.

  • 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.

     

  • 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.
