About this Research Topic

Background

Type 1 diabetes is a multifaceted autoimmune disease in which pancreatic beta cells are destroyed by autoreactive T cells. The incidence of type 1 diabetes has been rising globally. While genetic predisposition plays a significant role, it alone cannot fully explain the recent global rise in the incidence of the disease. This suggests that environmental factors are crucial contributors to the development of type 1 diabetes. Hence understanding the interplay between genetics and environmental triggers is imperative. Epigenetic mechanisms, including DNA methylation, histone modification, and chromatin accessibility, are key determinants in the regulation of gene expression and can provide insights into how environmental factors influence disease development.

There is a growing body of evidence linking epigenetic modifications with long-standing type 1 diabetes. However, the epigenetic changes that occur before seroconversion—marked by the development of autoantibodies against beta cell-specific antigens—are only beginning to be understood. These early changes are critical, as they may offer insights about the initial triggers of autoimmunity and provide opportunities for early intervention.

This article collection aims to explore and highlight the epigenetic changes in T cells that precede the onset of type 1 diabetes or the development of autoimmunity. Recent advancements in the field have significantly enhanced our ability to study these changes. Advances in whole-genome DNA methylation approaches and along with transcriptomics and histone profiling at single cell resolution using scRNA-seq and scCUT&Tag-seq have opened new avenues for high-throughput and high-resolution analyses, making it possible to investigate the epigenetic landscape of T cells in unprecedented detail.

We invite researchers to contribute to this collection with original research articles, reviews, and mini-reviews that delve into various aspects of epigenetics in the context of type 1 diabetes. Topics of interest include, but are not limited to:

· DNA methylation analysis: Studies that explore methylation patterns and their impact on T cell function and disease progression.

· Histone modification: Research examining how histone modifications influence gene expression and T cell behaviour in type 1 diabetes.

· Chromatin accessibility: Investigations into how chromatin structure changes affect T cell activation and autoimmunity.

· Regulation by non-coding RNAs: Articles focusing on the role of non-coding RNAs, including miRNAs and long non-coding RNAs, in the epigenetic regulation of T cells.

By bringing together cutting-edge research in these areas, this article collection aims to advance our understanding of the epigenetic regulation of T cell function in type 1 diabetes. We hope to uncover potential biomarkers for early diagnosis and identify new therapeutic targets that could lead to more effective treatments for type 1 diabetes.

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 they fall 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.
