Background

Satellite glial cells (SGCs) are specialized glial cells that encapsulate neurons in peripheral ganglia, providing structural and functional support. Recent studies suggest that SGCs play a crucial role in regulating neuronal lipid metabolism, which is increasingly recognized as a key factor in modulating neuronal excitability and pain processing. Dysregulated lipid metabolism in neurons has been implicated in neuropathic pain, diabetic peripheral neuropathy (DPN), and other chronic pain conditions. However, the precise mechanisms by which SGCs influence neuronal lipid metabolism and how this affects pain remain poorly understood.


This Research Topic aims to explore the molecular and cellular mechanisms through which SGCs regulate lipid metabolism in neurons and how these interactions contribute to pain modulation. By integrating insights from neuroscience, glial biology, and lipidomics, this collection will provide a comprehensive overview of the emerging role of SGCs in pain pathophysiology. Contributions from diverse research fields, including cellular and molecular biology, electrophysiology, single-cell analysis, and clinical pain research, will be encouraged to provide a holistic understanding of this topic.


This Research Topic will include, but is not limited to, the following themes:


1. SGCs and Lipid Metabolism:

- Molecular pathways by which SGCs regulate lipid synthesis, transport, and degradation in neurons.

- The impact of lipid metabolism on SGC-neuron interactions.


2. SGCs in Neuropathic Pain:

- How lipid metabolic changes in SGCs influence neuronal excitability and pain perception.

- The role of SGCs in chronic pain conditions such as diabetic neuropathy, chemotherapy-induced neuropathy, and post-injury pain.


3. SGCs and Neuroinflammation:

- The interplay between lipid metabolism and inflammatory responses in SGCs.

- How SGC-mediated lipid signaling modulates macrophage polarization and neuroimmune crosstalk.


4. Therapeutic Perspectives:

- Potential pharmacological or genetic interventions targeting SGC lipid metabolism for pain relief.

- Advances in lipidomics-based biomarkers for pain diagnosis and treatment monitoring.


5. Novel Methodologies and Techniques:

- Application of single-cell RNA sequencing, spatial transcriptomics, and imaging techniques to study SGC-neuron interactions.

- Experimental models and in vivo approaches to investigate SGC function in lipid metabolism and pain.


Article Types:

- Original Research Articles presenting novel experimental findings on SGCs and lipid metabolism in pain.

- Review Articles summarizing current knowledge and future directions in this field.

- Methods Papers describing innovative techniques for studying SGC-neuron interactions in lipid metabolism and pain.

- Case Reports and Clinical Studies providing insights into lipid metabolism-related pain disorders.

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.
