About this Research Topic

Background

Maintaining the structure and function of the skin is vital to the human body. Wound repair is susceptible to multiple internal and external factors, which can result in scarring and the formation of chronic difficult-to-heal, or recurring wounds. Compromised wound healing makes clinical treatments increasingly difficult, predisposes to dehydration and infection, and can lead to ulcers, gangrene, amputation, and even death. Skin regeneration involves the interactions of many cell types, and is characterized by changes in their phenotypes and behavior. Moreover, a number of signaling pathways critically regulate wound healing. Therefore, these cells, receptors, and signaling pathways are important potential drug targets in trauma treatment research. At present, however, there is still a lack of safe interventions with improved efficacy for the clinical treatment of chronic/large-scale trauma. Therefore, research focusing on the discovery and development of new drug molecules and targets that promote skin tissue regeneration, can have major clinical significance and impact.

Despite recent advances in gene and stem cell therapy, current interventions are still inadequate, largely due to the extremely complex mechanisms underlying tissue regeneration. Therefore, the discovery, development, and analysis of new drugs remain critical. Peptides, which are characterized by their high activity, target specificity, and stability, play a unique role in basic scientific research and innovative drug development. They are not only powerful tools for the discovery and confirmation of new drug targets but serve as important candidates or lead molecules for the design of new drugs. In recent years, pro-healing peptides have attracted significant attention all over the world for their vast array of potential applications, including drug development and utilization as molecular probes to illustrate novel mechanisms involved in skin wound healing. As the related research is still in its infancy, many important key breakthroughs can be anticipated.

The topic “Pharmacology and mechanisms of skin tissue regeneration-promoting peptides” will include the following issues:
• Discovery of new peptides with efficacy to promote skin wound healing/tissue regeneration.
• Application of peptides as molecular tools to analyze the mechanisms of skin wound healing, focusing on (but not limited to) related signaling pathways and epigenetic mechanisms.
• Identification of new drug targets for improving skin wound healing.
• Peptide-based approaches to promote skin wound healing.

Keywords: Peptide, wound healing, tissue regeneration, drug intervention targets, nucleic acid drugs

Frequently asked questions

• What is a Research Topic?

  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.

• Why does Frontiers publish Research Topics? 

  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.

• Why are Research Topics important for journals?

  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.

• How do we ensure the quality of articles within Research Topics?

  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.

• What are the benefits of publishing my article in a Research Topic?

  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.

   
• What types of articles can be published in a Research Topic?

  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.

• Who leads a Research Topic? 

  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.

• What is the role of a topic editor?

  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.

• What support will I receive when editing a new Research Topic? 

  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.
