Background

BACKGROUND

Neutrophils are the most abundant leukocytes in human blood and constitute the first line of defense against pathogens.

Their activation, leading to phagocytosis, degranulation, and the release of Neutrophil Extracellular Traps (NETs), is crucial for innate immunity. However, dysregulated or excessive neutrophil activation is a hallmark of numerous chronic inflammatory and autoimmune diseases, such as rheumatoid arthritis, sepsis, acute lung injury, and atherosclerosis.

Current strategies to control hyperactive neutrophils often lack specificity and can lead to immunosuppression. In this context, natural compounds (derived from plants, marine organisms, or microorganisms) represent a vast and largely untapped reservoir of bioactive molecules. These compounds offer exceptional chemical diversity and have historically been a prolific source of pharmacologically active agents, presenting a promising avenue for the discovery of novel, targeted immunomodulators with potentially fewer side effects.



GOAL

The primary goal of this Research Topic is to collate cutting-edge research that elucidates the mechanisms by which natural molecules modulate neutrophil functions, including recruitment, activation, oxidative burst, NETosis, and apoptosis. While the therapeutic potential of many natural products is acknowledged, a systematic understanding of their direct molecular targets and signaling pathways in neutrophils is often lacking.

This collection aims to bridge this gap by fostering interdisciplinary studies that combine phytochemistry, pharmacology, and immunology. We seek to highlight recent advances in the identification and characterization of novel natural compounds, the repurposing of known molecules, and the development of natural product-inspired synthetic analogs with an immunological perspective.

Ultimately, this topic will provide a comprehensive platform to explore how these molecules can be harnessed to fine-tune neutrophil responses, thereby paving the way for the development of next-generation therapeutics for inflammation-driven pathologies. We welcome contributions that move beyond descriptive findings to offer mechanistic insights and validate efficacy in robust in vivo models on immune system disorders.



SCOPE

This Research Topic will define the current landscape and future directions of natural product research in neutrophil biology and its immunomodulatory properties.
We aim to cover the entire spectrum, from the discovery of novel bioactive compounds to the detailed dissection of their anti-inflammatory mechanisms.

We welcome the submission of Original Research, Review, Mini Review, and Perspective articles on themes including, but not limited to:

• Discovery and Characterization: Screening of plant, marine, or microbial extracts for neutrophil-modulating activities.
• Mechanistic Insights: Elucidation of signaling pathways (e.g., MAPK, PI3K/Akt, NF-κB) and molecular targets affected by natural compounds and involved on immune modulation.
• NETosis Regulation: The role of natural products in inducing or inhibiting the formation of Neutrophil Extracellular Traps (NETs).
• Inflammation Resolution: Contributions to promoting neutrophil apoptosis and efferocytosis.
• Preclinical and Clinical Studies: Efficacy evaluation of natural compounds in models of sterile inflammation, infection, and autoimmunity.
• Drug Delivery and Formulation: Novel approaches to enhance the bioavailability and efficacy of natural immunomodulators.

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.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
