About this Research Topic

Background

Aging gut microbiota and intestinal mucosal layer, including immune cells alter host physiology and enhance the prevalence of various health issues. These effects may be due to dysbiosis, dysfunctional immune function, and activation of inflammatory cytokines resulting in silent low-grade inflammation. Aging dysbiosis leads to metabolic disorders in various cellular systems and is one of the major factors of metabolic syndromes such as obesity, atherosclerosis, insulin resistance, glucose intolerance including local inflammatory diseases, and IBD to systemic inflammatory disorder and cancer. Aging gut microbiota-induced metabolic disorders increase the aging of host cells and affect the overall life of the individual. Aging gut microbiota and mucosal immunology affect the Central Nervous System function by altering the gut-brain axis. This may lead to various chronic neuroinflammatory disorders such as Alzheimer’s disease. Similarly, aging gut microbiota may affect cardiovascular function that provokes age-related cardiovascular dysfunctions in individuals. Thus, aging microbiota may alter the homeostasis of the immune system and lead to CNS, cardiovascular and metabolic dysfunction, etc.

Our goal is to collect research information on various diseases and immunological disorders induced by aged microbiota and downstream cellular signaling. It is important to know how aged microbiota affects intestinal cellular immunology and thereafter interactions with various organs to alter their homeostasis and pathophysiological mechanisms. These research articles will highlight the various new therapeutic targets for metabolic as well as CNS diseases provoked by aged gut microbiota.

Under this umbrella topic, we would like to invite different scientists and research scholars working in aging microbiota and intestinal immunology. That also includes a molecular mechanism and cellular signaling of aging microbiota and its effects in metabolic syndromes, including epigenetics and other responses. This Research Topic will include novel research in the field of aging gut microbiota and related articles.

We welcome manuscripts including review articles, mini-reviews, and case reports covering the following (but not limited to) topics:

•Aging microbiota and inflammatory disease

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.
