Drug Discovery for Emerging and Neglected Tropical Diseases: Advances, Challenges and Perspectives

About this Research Topic

Background

Neglected tropical diseases (NTDs) are a diverse group of conditions that affect over 1 billion people in low- and middle-income countries, characterized by poor governmental support, scarce funding, and a lack of innovative actions toward control and treatment. Caused by a variety of agents, including viruses, fungi, bacteria, protozoan, and worms, NTDs occur mainly in tropical areas. Nonetheless, current environmental and social changes boost the dissemination of NTDs into non-endemic regions, expanding the population at risk.

Within this context, two scenarios aggravate global public health: the emergence of new and the reemergence of old tropical diseases, especially after the COVID-19 pandemic period, and mostly because of antimicrobial resistance and failure of public health measures.

The social and economic impact of emerging/reemerging and neglected tropical infections worldwide highlights the crucial need for successful approaches to controlling/eradicating these diseases.

Since effective vaccines are not broadly available, the therapeutic approach remains the most important strategy to control and manage emerging and neglected tropical diseases. Thus, the development of novel treatments or the improvement of the available ones remains a constant need. Despite the progress in this field, mainly due to scientific/technical advances, engagement of the scientific community, and increasing public-private partnership efforts, several gaps in early drug discovery persist, constricting the development of novel antimicrobial agents.

Therefore, this Research Topic aims to publish data on recent progress in early drug discovery for emerging/neglected tropical diseases, including parasitic, bacterial, viral, and fungal infections. Here, we will gather valuable insights related to the development of new experimental approaches, identification of novel therapeutic strategies, and mechanism of action of classical or new antimicrobials.

In this Research Topic, we welcome submissions of Original Research and Review articles, on the following (but not limited to) topics:

- Development of in vitro models of early drug discovery for tropical diseases;
- Experimental low, medium, and high-throughput approaches (including target-based and cell-based assays) to identify novel drug candidates against emerging and neglected tropical diseases;
- Novel therapeutic strategies for emerging and neglected tropical diseases;
- Drug repurposing/drug combination for the development of novel drug candidates;
- In vitro ADME-Tox assays to support the drug discovery pipeline;
- Mechanism of action of known or novel antimicrobials.

We would like to extend special thanks to the coordinator of this Research Topic Dr. Denise Pilger who is currently affiliated with the University College London, United Kingdom.

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.
