About this Research Topic

Background

Dental caries are associated with a dysbiotic shift towards acidogenic, aciduric and saccharolytic species. Streptococcus mutans has been considered a primary causative pathogen of dental caries with the major virulence factors including biofilm formation, acidogenicity, and aciduricity. Additionally, recent studies have detected other virulence factors, the collagen-binding proteins (Cnm and Cbm), which are associated with hemorrhagic stroke and infective endocarditis. In addition to functional studies of S. mutans, including molecular mechanisms related to biofilms on the tooth surface, carbohydrate metabolism, or strategies to survive under acidic environment, newer approaches in S. mutans biology research have recently been adopted and developed, such as the investigation of S. mutans physiology and diversity through next-generation sequencing technologies and how S. mutans interspecies interactions affect the oral biofilm development. The glucans produced by S. mutans play a central role in establishing a steady extracellular polysaccharide (EPS) matrix for other bacterial colonization and a diffusion barrier to maintain the favorable acidic environment for the cariogenic bacteria. Therefore, although dental caries is a disease caused by polymicrobial, it has been largely accepted that selective targeting of S. mutans is an effective strategy for dental biofilm prevention. Antimicrobial agents that selectively target cariogenic bacteria, such as S. mutans, without disrupting the beneficial commensal flora have been considered promising novel approaches for caries prevention and control.

This Research Topic aims to unravel the unknown biological aspects of S. mutans and other caries-associated species, including how it senses and responds to environmental conditions through interconnected circuits that regulate various virulence expressions such as biofilm formation, acid production, or acid tolerance. A better understanding of these physiological features may facilitate the exploration of new targets for the control of cariogenic species and the development of potential novel therapeutics that specifically target those.

We invite scientists to contribute to this Research Topic in the forms of original research articles or reviews. Authors are welcome to submit their articles that cover but are not limited to the following areas:

• Virulence factors of cariogenic species: biofilm formation, acid production, acid tolerance, collagen-binding proteins
• Signaling pathways of S. mutans: two-component signal transduction systems and quorum sensing
• Mutacins produced by S. mutans
• Interspecies and cross-kingdom interactions of cariogenic species
• Antimicrobial agents that specifically target cariogenic species, such as S. mutans, as a novel anticaries strategy

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?
