About this Research Topic

Background

The etiology of many psychiatric disorders such as schizophrenia, major depressive disorder, bipolar disorder, and psychosis remains to be fully understood. Consequently, the development of more efficient and precise diagnoses and therapies remains an important challenge. A growing body of evidence suggests inflammation is a key player in the etiology and pathomechanisms of psychiatric disorders, with peripheral immune cells that include T and B cells, and their circulatory effector molecules such as cytokines, infiltrating and affecting central nervous system (CNS) function. While in healthy conditions a crosstalk between the peripheral system and the CNS ensures a coordinated maintenance of CNS homeostasis, under pathological conditions a compromised blood-brain barrier and/or blood-CSF barrier, can lead to altered CNS functions, with deleterious outcomes on behaviour and cognition associated with psychiatric disorders.

The goal of this Research Topic is to better describe the association between peripheral immune cells and neuropsychiatric disorders. It is crucial to elucidate whether the peripheral immune response is a cause or consequence of neuropsychiatric disorders, and whether targeting the peripheral immune cells could serve as a disease-modifying therapy. The comparison of peripheral and CSF immune cells in same patients especially would be of great interest herein. In addition, there is a need for early diagnostic tools that allow for a specific diagnosis and accurate classification of neuropsychiatric diseases. It is also critical that potential biomarkers are validated clinically and proven to be reproducible, sensitive, and specific.

We particularly welcome submission of Original Research, Review, Mini-Review, Hypothesis and Theory, Perspective, Clinical Trial, Case Report and Opinion article focusing on, but not limited to the following subtopics:

• Relation between blood immune cells and CSF immune cells

• Blood immune cells in psychiatric and neurological disorders

• CSF cells in neurological and in psychiatric disorders

• Relation of blood cytokines levels and blood immune cells

• Roles of the peripheral immune system in psychiatric disorders

• Omics approaches (genomics, transcriptomics, proteomics and metabolomics) to study peripheral immune cells and their mediators in neuropsychiatric disorders

• Interactions with central non-neuronal cells (e.g., microglia)

• Underlying cellular and molecular mechanisms

• Outcomes of treatments acting on peripheral cells

• Influence of the environment and context (e.g., stage of life)

• Sex differences in these outcomes and mechanisms

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.
