About this Research Topic

Background

Inhalation toxicology refers to the route of exposure whereby an inhaled substance can cause direct local toxicity to the airways or exert their action systemically following absorption and metabolism. Assessing the inhalation safety of substances is applicable to many sectors producing new products with intended or inadvertent inhaled exposure (e.g. pharmaceutical, chemical, environmental, consumer products). Limitations with current tools and approaches to assessing inhalation safety prevent a high proportion of these products ever making it to market due to preclinical safety concerns in animals, despite not understanding the relevance of these responses in humans.


Assessing the safety of substances in the lungs requires in depth knowledge of the properties of the inhaled aerosol, deposition within the lungs, interaction with biological barriers and the innate immune system and translation of these events to human safety. As such, advancements in inhalation toxicology rely on interdisciplinary research between the interfaces of the biological and physical sciences. Assessing the inhalation safety of substances applicable to many areas which traditionally have used different approaches (e.g. pharmaceutical, chemical, environmental, consumer products).
However, the challenges of providing relevant dosing, replicating exposure, categorizing adaptive and adverse responses and applicability of human relevant inhalation risk assessment remain a challenge to all sectors. This research topic aims to explore new approaches and technologies within inhalation toxicity and other related fundamental research including aerosol characterisation which have the potential to answer the unmet needs within safety assessment.

- Inhalation dosimetry

- Aerosol science within inhalation

- New approach methodologies for inhalation toxicity

- In vitro-in vivo correlation

- Particle-lung interactions

- Physical characterization of inhaled particle properties

- Retention of inhaled products and local pharmacokinetics

- Mucus/surfactant interactions with inhalants

- Immunological response of the airways

- Understanding/characterizing the mechanistic pathways of response to inhaled stimuli

- Interpretation of inhalation toxicity studies for human relevant safety assessment

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.
