Background

The experimental models have been extensively used over the centuries as important tools to elucidate the inflammatory mechanisms enrolled in the physiopathology of different diseases. The more we understand the mechanisms enrolled in the disease development and progression, the closer we are to therapeutic targets and consequent new proposals for therapeutic management. In respiratory diseases, such as chronic obstructive pulmonary disease, animal models have been useful and resemble several features observed in the clinic of this disease. Cigarette smoke (CS)- and Elastase-induced models have been the most employed models of COPD and highlight different inflammatory signaling pathways that orchestrate the development and progression of COPD. Thus, many potential future therapeutics for COPD whose are currently in clinical development were identified as potential therapeutic targets in pre-clinical research notably using experimental models. In this context, the advances in cellular and molecular techniques have been essential for the success of the development of experimental models to allow a deeper investigation of molecular mechanisms and possible biomarkers orchestrating COPD.

Since COPD is a multifactorial disease, it is difficult to find an animal model that resembles all clinical features at once. However, there are many experimental approaches described in the literature. And depending on the interest area, researchers could choose among them, based on the advantages and disadvantages of each model. For example, the CS-induced models are recognized by better representing the etiology of this disease in humans, since smoking is a main risk factor for COPD development due to the chronic inflammatory process induction. However, the elastase-induced models have been extensively used to describe the remodeling process of the different extracellular matrix components of tissue lung after its destruction by the proteases. At this moment, the scientific community has been moving efforts to elucidate the molecular mechanisms that orchestrate these events described in this disease physiopathology.

In this Research Topic, we aim to present a collection of manuscripts describing the newest findings in the cellular and molecular mechanisms enrolled in the inflammatory process and tissue lung destruction and remodeling based on the animal models of COPD. We welcome studies as Original Research, Method, Mini Review, and Case Report articles, focusing on, but not limited to, the following subtopics:

--Immunological mechanisms in COPD models
--Inflammatory signaling pathways in COPD models
--Inflammasomes in COPD
--Regulation of immunity by miRNA in COPD
--Immunological mechanisms in animal models of COPD exacerbation

Please note that manuscripts without a strong immunological focus (not just inflammation) are out of scope for this Research Topic.

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.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

     

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • 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. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
