Background

Santiago Ramón y Cajal's pioneering studies marked the beginning of a profound exploration of the complexities of the central nervous system (CNS), which includes the brain, spinal cord and retina. Over the years, it has become increasingly clear that the CNS is one of the most sophisticated systems in the human body, characterised by delicate interactions between neurons and glial cells, and by the considerable challenges posed by the low permeability of its protective barriers.

The conventional perception of the CNS as an immunoprivileged system has been widespread since Cajal's era. This notion was rooted in the belief that the CNS is shielded from the full array of immune responses to safeguard delicate neural tissues. However, recent studies have begun to challenge this perspective. There is an increasing recognition that inflammation plays a critical role in neurodegenerative diseases of the CNS, including Alzheimer’s disease, amyotrophic lateral sclerosis, Parkinson’s disease, and multiple sclerosis (MS). Differential immune responses involving the adaptive versus the innate immune system are observed at various stages of neurodegenerative diseases and may not only drive disease processes but could serve as therapeutic targets.

This revelation transforms our understanding of the CNS and its vulnerabilities, emphasizing the intricate interplay between neural and immune systems. The exploration of communication channels between the CNS and peripheral tissues gains even more significance, as inflammation emerges as a pivotal player in the pathogenesis of neurodegenerative disorders. The recognition of distinct immune responses throughout the progression of these diseases not only sheds light on the complex mechanisms at play but also offers potential avenues for targeted therapeutic interventions. In this context, the application of cellular therapies in clinical settings must be reevaluated in light of the immune dynamics involved, urging researchers to refine their strategies for more effective and personalized treatments in the realm of neurodegenerative diseases. This evolving landscape underscores the dynamic nature of neuroscience, necessitating a continuous reassessment of paradigms to address the ever-expanding complexities of the CNS.

This Research Topic endeavors to encompass a diverse array of contributions, including original research comprising observational and experimental studies, along with other valuable contributions such as perspectives, reviews, and mini reviews. While the central focus revolves around several key themes, it is essential to emphasize that the scope of this research initiative extends beyond these specific areas to encourage a broad exploration of topics related to the intricate interplay between the central nervous system (CNS) and the immune system.

Examples of key themes:

• The role of the immune system in CNS disease.

• Mechanism of actions of cells used in therapy (focusing on pluripotent cells such as mesenchymal cells, which do not raise ethical issues).

• Immunological biomarkers of cell therapy success.

• Developing novel methods to study the immune effect of cell therapy in the CNS.

• Cross talk between the immune system and the CNS.

• Immune recognition in the CNS

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.
