About this Research Topic

Background

The gut and the lungs are part of a complex system that is critical for maintaining the overall health of an individual. Increasing evidence suggests that gut microbiota can influence the immune responses in remote organs, such as the lungs. The gut-lung axis refers to the bidirectional communication between the gut microbiota and the lungs, which plays a critical role in regulating immune responses and preventing infections. Recent studies have shown that the gut-lung axis is modulated by microbes/microbial products and other signals from the intestinal mucosa, which contribute to the regulation of local and systemic immunity. Furthermore, imbalances in the gut microbiota have been linked to several respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), highlighting the importance of maintaining the balance of the healthy microbial community. This research topic aims to investigate the role of mucosal microbiota in the immunomodulation of the gut-lung axis and its implications for health and disease. The findings from this research can shed more light on the interactions between the gut and the lungs and inform the development of novel therapeutics for respiratory diseases.

This research topic aims to achieve several goals including characterizing the microbiota composition and diversity of healthy individuals and individuals with respiratory diseases, investigating the role of gut microbiota and bacterial products in regulating immune responses in the intestine and lung, exploring the impact of diet and environmental factors on the gut-lung axis, evaluating the potential of probiotics, prebiotics, postbiotics and fecal microbiota transplantation (FMT) as treatments for respiratory diseases, identifying the mechanisms by which mucosal microbiota interacts with the lungs and immune cells in the respiratory tract and developing a risk assessment model to predict individuals who are at higher risk of respiratory infections based on their gut microbiota and immune function.

Achieving these goals can help develop a better understanding of the microbiota-immune interactions in the gut-lung axis. This, in turn, can inform the development of new prevention and treatment strategies for respiratory diseases. By characterizing microbial markers and intercellular mechanisms involved in the gut-lung axis, researchers can identify new targets for intervention and help to optimize the use of existing treatments such as FMT, probiotics, and prebiotics. Overall, this research topic has significant potential to improve our understanding of the gut-lung axis and contribute to the development of more effective prevention and treatment strategies for respiratory diseases.

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?
