About this Research Topic

Background

Food matrixes, mainly of vegetable origin, contain metabolites that, when combined with other lifestyle interventions, can promote human health and well-being. Secondary metabolites from plants have been demonstrated to protect humans against oxidative damage, which contributes to the development of chronic degenerative diseases, including cardiovascular, neurodegenerative, and metabolic diseases, as well as cancer. Furthermore, specific classes of metabolites, such as polyphenols and carotenoids, act as radical scavengers and modulate intracellular redox states through the regulation of antioxidant enzyme activities.

In an attempt to discover new compounds, hemp phytocannabinoids, which are non-psychoactive and potentially beneficial to human health, have gained increasing interest. The pharmacology of minor cannabinoids remains incomplete, but studies indicate that they have antagonistic and agonistic effects on a number of receptors, including the cannabinoid receptors CB1 and CB2, vanilloid receptor 1 (TrpV1), and serotonin 5-HT1a receptor. These receptors are involved in the cellular processes that cause neurodegenerative diseases, epilepsy, and cancer.

A complete understanding of the mechanisms of action of metabolites is still elusive, as is knowledge of the mechanisms underlying chronic degenerative conditions. The combination of specific metabolites enhances the antiproliferative effects as well as redox metabolism. Their ability to activate multiple signaling pathways may yield a synergistic effect that will require further investigation to determine how they perform their preventive function against chronic diseases. This Research Topic aims to identify potential molecular targets of metabolites and to develop new innovative functional formulations.

The purpose of this collection is to provide a comprehensive analysis of metabolites, such as polyphenols and carotenoids, as well as hemp phytocannabinoids, with regards to their potential protective impact on degenerative diseases. We welcome manuscripts (Original Research, Perspectives, Mini Reviews, Commentaries, and Opinions) assessing the biological effects of Carotenoids, polyphenols and phytocannabinoids. The focus should be on the modulation of processes, including autophagy, senescence, and redox cellular metabolism of carotenoids and phytocannabinoids relevant in the prevention of chronic diseases:

- In vivo and in vitro studies on the effects of formulation using such metabolites
- Development and assessment of innovative formulations of the aforementioned metabolites
- Assessment of approaches and technologies for improving the bioavailability of these metabolites
- The effect and mechanisms of carotenoids and phytocannabinoids on cellular redox state involved in several pathological conditions

All the manuscripts submitted to the collection will need to fully comply with the Four Pillars of Best Practice in Ethnopharmacology (you can freely download the full version here).). We also expect that the MS follow the standards established in the ConPhyMP statement Front. Pharmacol. 13:953205. Specifically please note, chemical anti-oxidant assays like the DPPH assay are of no pharmacological relevance but are simply chemical and analytical tools . Therefore, they cannot be used in a pharmacological assessment.

Keywords: Polyphenols, carotenoids, phytocannabinoids, oxidative stress, antioxidants

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.
