Background

Kidney disease is one of the leading causes of death and suffering in the 21st century. In 2017, the Global Burden of Disease (GBD) Chronic Kidney Disease Collaboration reported approximately 700 million cases worldwide and a 40% increase in prevalence over the past 30 years. In addition, chronic kidney disease (CKD) is projected to become the fifth leading cause of death globally by 2040.

One of the most common characteristics of kidney disease is the development and progressive increase of albuminuria/proteinuria, as well as tubulointerstitial injury, inflammation, and fibrosis. Recent findings have highlighted that, at the onset of kidney disease from various etiologies—during the subclinical stages—tubular changes may even precede alterations in glomerular structure and function. These observations have placed renal tubules at the center of the pathogenesis and progression of both acute and chronic kidney diseases.

Several cellular and molecular mechanisms have been proposed to mediate the development of tubulopathies. These include dysregulation of tubular epithelial cell turnover, cell senescence, autophagy/mitophagy, dedifferentiation, epithelial–mesenchymal transition, pro-inflammatory and pro-fibrotic phenotypes, as well as disruptions in the tubular metabolic state and various transport mechanisms. All of these processes are influenced by the modulation of autacoids, hormones, and inflammatory mediators within the tubular microenvironment. Despite advances in the field, the interactions among these factors remain poorly understood.

Regarding the treatment of kidney diseases, some of the cellular and molecular processes observed in various tubulopathies have been partially modulated by renin–angiotensin system (RAS) inhibitors—such as angiotensin receptor blockers and ACE inhibitors—sodium-glucose cotransporter 2 (SGLT2) inhibitors, and other promising compounds. These agents have also been shown to improve clinical outcomes in patients with kidney disease. However, their renoprotective effects are still not fully understood. Therefore, there is an urgent need to discover, design, and test new compounds that can prevent or even halt the development of tubulopathies and the progression of kidney disease.

This Research Topic aims to deepen our understanding of the complex pathophysiological mechanisms underlying different tubulopathies, as well as to discuss promising new pharmacotherapies, including their pharmacokinetics, pharmacodynamics, and safety under both physiological and pathological conditions. In this context, we welcome submissions of original research, systematic reviews, reviews, mini-reviews, hypotheses, clinical trials, theories, and perspectives addressing (but not limited to) the following topics:

- New pathophysiological mechanisms in tubulopathies, based on animal and/or human studies;

- Pharmacokinetic and pharmacodynamic studies of novel therapeutic agents for tubulopathies;

- Animal and/or human studies related to tubular injury in subclinical kidney disease;

- Studies showing the tubular damage as cause or consequence of progressive chronic glomerular dysfunction or injury;

- Studies showing renal tubules injury and dysfunction in the setting of acute kidney injury and chronic kidney disease;

- Studies involving new antiproteinuric agents;

- Innovative therapies for tubulopathies;

Topic editors

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
