About this Research Topic

Background

Lifespan is increasing worldwide, but health span has not shown a similar rate. Human aging has been associated with a decline in biological resilience and the risk of diseases grows exponentially over time, depending on hereditary, environmental factors, lifestyle, mental health, and stochastic factors. Despite this fact, old age does not necessarily result in poor health and not all age-related changes are maladaptive. Some aged individuals delay or escape frailty and/or achieve exceptional longevity. Combining different biomarkers have been proposed to understand why and how people become old at different rates and how they can be used to achieve healthy aging. Thus, it is important to better understand the determinants of healthy aging and their interventions to slow the aging process, reduce disease burden and high-cost dependency, and extend healthy life expectancy.

Since aging is not a single process and impacts several biological pathways simultaneously, no single measurement has proven to be useful so far. Thus, identifying a set of biomarkers of aging in combination would be a better tool to measure “biological” age and monitor health through life than any marker in isolation. Biomarkers of aging could be the key to predicting near or long-term morbidity and/or mortality risk and assist in promoting healthy behaviors earlier in life to reach older ages healthier. They may also help in the early detection of the risk of fragility and characterize normal, accelerated, and exceptionally successful aging. In addition, molecular and cellular markers can correlate strongly with relevant functional and cognitive parameters.

Differences between populations and within individuals make it harder to determine, evaluate or reproduce the indicators for unsuccessful aging or healthy aging. Thus, we need to identify and investigate those biomarkers signatures, once the challenge involves the applicable, reproducible, and predict future health and survival better than chronological age. Future advances need to provide more practical implications for the policy of healthcare to extend healthy life expectancy in an increasingly aging population. We welcome submissions that focus on the following aspects, but are not limited to:

•Biomarkers of physical capability and cognitive function
•Biomarkers of physiological function; well-being
•Biomarkers combinations and clinical health span-extending interventions
•Biomarkers of immune function and immunosenescence
•Measure of biological aging: challenges and practical utility
•Epigenetic marks of aging
•Metabolism, endocrine, nutrition, and biochemical measurements for healthy aging
•Levels of inflammation: balance between inflammaging and anti-inflammaging mechanisms
•Cellular, molecular, and immunological modification processes, not all age-related changes are maladaptive.
•Combining different biomarkers as a new target for interventions to slow the aging process and reduce fragility in its early stages

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.
