About this Research Topic

Background

Increase in age of the world population has led to exponential rise in age-related neurodegenerative diseases. Accumulation of stress in an organism, such as oxidative and DNA damage, unfolded protein response, and organellar dysfunctions, may lead to neurodegeneration in later years. Factors like age and co-morbidities like diabetes worsen the damage accrued over time. Determining the time of initiation for a pathological event and understanding how different stress pathways are regulated and coordinated at the cellular and organellar level, is of fundamental importance. There are biomarkers to monitor progression of cognitive dysfunction associated with different neurodegenerative disorders. Studies are also underway to develop targeted therapies to prevent or delay neurodegenerative diseases. However, identifying the earliest events leading to later disorders is necessary to stop or slow down progression of neurodegeneration.

How stress signals interact and affect each other at the earliest stages of neurodegeneration to aggravate the severity of the situation is unknown. Identifying the events that cause rapid cognitive decline are important to develop effective therapies that can be applied at the right time. The goal of this editorial section is to a gain a comprehensive understanding of how different brain cells such as glia, neurons etc. communicate with each other under stress. Several lines of evidence show that glial cells and neurons, as well as the cerebrospinal fluid surrounding all the brain structures accumulate pathological changes as animals age and demonstrate altered functionality. However, if these changes lead to future neurological disorders remain unknown. Therefore, we want to invite researchers to submit their work that will help us identify the initial pathological events in glia and neurons and understand how these events may lead to decline in cognitive health.

As a part of the Frontiers in Neurology journal, this special edition will offer a place to publish new research findings in the quickly developing fields of Molecular Neuroscience and Neurodegeneration. The research articles that we aim to publish in this special edition will range from Short Reports (1-2 Figures), Full Research Articles, Review Articles, and Articles Describing Novel Methods or Techniques. These novel scientific articles will undergo peer review by experts in the given subject area and advance our understanding of the cellular communications during the early pathological stages of neurodegeneration. We welcome original submissions from the research community, and we will prioritize articles where the reported findings show practical significance.

Keywords: Stress, neuro-glial communications, cognitive health, sleep, stroke, mitochondrial dysfunctions, neuropeptides

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

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.
