About this Research Topic

Background

Since the pioneering work of Bill Costerton, it has become evident that biofilm-associated infections encompass the large majority of infections in the human body. Many chronic infections including otitis media, rhinosinusitis, periodontal disease, prostatitis, lung infections in cystic fibrosis patients, recurrent urinary tract infections, and skin infections may be attributed to the formation of biofilms on host tissues. Not less important with regard to biofilm formation are the infections associated with the use of medical devices on which microorganisms can adhere, proliferate and eventually spread to other body sites. Despite the recognized importance of biofilms in medicine, our understanding of the human immune response to biofilms is still preliminary. While host responses have evolved efficient and complex mechanisms to deal with isolated, planktonic microorganisms, the same mechanisms do not seem to be equally efficient to tackle aggregates of microbial cells forming a biofilm that, rather, displays a high capacity to resist the clearance by host innate and adaptive immune responses.

A deep knowledge of the multiple interactions between biofilms and the immune system is critical to adequately address biofilm infections. The present Research Topic aims to gather a collection of papers addressing the immune response to bacterial/fungal biofilms. Special interest will be devoted to studies elucidating basic immune pathways possibly contributing to a protective immune response to biofilms, but also to the sophisticated mechanisms exploited by biofilm cells to evade such response. Biofilm-forming microorganisms are structurally and metabolically different as compared to their planktonic counterpart. Typically, they are embedded in a complex mixture of extracellular polymeric substances (EPS) they themselves produce that includes polysaccharides, proteins, lipid and extracellular DNA. Recent research has elucidated that EPS components may represent a source of biofilm specific antigens able to exert immunemodulating properties. The composition of EPS may greatly differ between a microbial species and even between strains within the same species, thus adding complexity to the elucidation of host immune responses to biofilm constituents. Identification of biofilm-specific antigens “seen” by host immune cells, as well as quantitative measurements of the host responses to biofilms, may help in identifying new anti-biofilm immunotherapeutic strategies as well as biomarkers of biofilm-associated infections.

The scope of this Research Topic is to provide a comprehensive overview of the actual knowledge of the host immune response to microbial biofilms. We seek Original Research, Review, Mini-Review, Hypothesis and Theory, Perspective, Clinical Trial and Case Report articles that cover, but are not limited to, the following topics:

• The role of innate immunity in host response to microbial biofilms
• The role of acquired immunity in host response to microbial biofilms • Identification of biofilm-specific ligand-receptor interactions during host defense
• In vitro and in vivo models/techniques to study the immunity to biofilms
• Immunotherapeutic approaches against biofilms
• Host responses promoting biofilms

Keywords: biofilm, biofilm infections, innate immune response, acquired immune response

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.
