Diabetes: Molecular Mechanisms
The Section seeks to present novel, ground-breaking preclinical studies on molecular aspects of type 1 and type 2 diabetes aimed to increase understanding of fundamental aspects of each disease process, and potential therapies. The section will thus focus on fundamental research into the biology of systems and disease-relevant tissues, including, but not limited to, pancreatic islet and enteroendocrine (L, K, I) cells, “classical” insulin target tissues (liver, muscle, adipose tissue etc), and non-classical tissues (brain, immune system etc). Studies describing technologies advances in this area are also particularly welcome. Clinical research studies or epidemiological studies do not fall within the scope of this section.
Research on the following themes will be particularly welcome:
• Basic metabolism and metabolic regulation. Inter-relationships between different metabolic fuels and the resulting effects on diabetes-relevant phenotypes (fatty acid, amino acid and glucose metabolism);
• Systems level regulation of glucose metabolism and inter-organ and inter-cellular communication. Integration of basic metabolism with diabetes-relevant cellular functions: β-cells, skeletal muscle, hepatic gluconeogenesis etc (adipose-liver, gut-brain etc). The microbiome and its interaction with these systems;
• Control of feeding and satiety and its relationship to tissue damage in type 2 diabetes. Role and regulation of neural circuits (hypothalamus, hind brain etc);
• β cell failure (dysfunction, apoptosis, ER stress, altered proliferation etc ) in type 1 and type 2 diabetes. Relationship with obesity and fuel exceess. Immune mechanisms of pancreatic β cell destruction in type 1 diabetes, and its targeting by immune therapies. Immunomodulation and immunometabolism;
• Functional genomics, genetic models of gene function/dysfunction in mouse and other model organisms including non-mammalian species (Yeast, C. elegans, Drosophila, zebrafish etc). Modelling genetic variants associated with diabetes (GWAS etc.);
• Control of adipose tissue development and differentiation, insulin action, adipokine production;
• Disease complications: metabolism of liver and kidney: nephropathy, neuropathy, retinopathy. Bone loss in diabetes;
• Receptor-ligand interactions and trafficking, particularly of receptors central to normal glucose homeostasis, e.g. insulin, GLP-1, relevant neurotransmitters. The molecular basis of receptor bias. Intracellular signalling (Ca2 , cAMP, phosphorylation cascades);
• Omics: transcriptomics, proteomics, metabolomics (MS-MS etc) lipidomics, RNAomics of plasma and tissues. Biomarkers of disease
• Intracellular organelle function and stasis: e.g. secretory granule dynamic, exocytosis and mitochondrial biology; autophagy, apoptosis; transmembrane transporters and molecular motors;
• Epigenetics and genomics: chromatin landscape, enhancer biology, genome stability, metabolism:epigenome interactions. Roles and regulation of non-coding RNAs;
• Translational models, e.g. high throughput screens of credible targets;
Technological advances pertinent to the field including:
• Genome editing (CRISPR etc)
• Metabolomics, lipidomics, metabolic flux profiling, metabolic modelling. ChiPSeq, RNASeq, mass spectometry, etc;
• Discovery and characterization of pharmacological tools and agents that are of use in the study or treatment of diabetes and related disorders;
• In vivo and in vitro imaging (novel probes, approaches); optogenetics, pharmacogenetcs and related technologies (DREADs, acoustic sensors etc); super-resolution microscopy (PALM STORM, SIM etc) and analytical tools. Imaging mass cytometry, CyTOF etc;
• Transplantation and new sources of transplantable tissues: Stem cell therapies, directed differentiation (e.g. iPSC to β cell conversion). Tissue encapsulation;
• Devices for hormone release in vivo (“artificial pancreas”);
• Single cell omic approaches and analyses;
• Computational biology, “big data”, machine learning and its applications. Data archiving and tissue atlases.

All manuscripts must be submitted directly to the section Diabetes: Molecular Mechanisms, where they are peer-reviewed by the Associate and Review Editors of the specialty section.
Frontiers' philosophy is that all research is for the benefit of humankind. Research is the product of an investment by society and therefore its fruits should be returned to all people without borders or discrimination, serving society universally and in a transparent fashion.
That is why Frontiers provides online free and open access to all of its research publications. For more information on open access click here.
Frontiers is fully compliant with open access mandates, by publishing its articles under the Creative Commons Attribution licence (CC-BY). Funder mandates such as those by the Wellcome Trust (UK), National Institutes of Health (USA) and the Australian Research Council (Australia) are fully compatible with publishing in Frontiers. Authors retain copyright of their work and can deposit their publication in any repository. The work can be freely shared and adapted provided that appropriate credit is given and any changes specified.
Under the Frontiers Conditions for Website Use and the Frontiers General Conditions for Authors, authors of articles published in Frontiers journals retain copyright on their articles, except for any third-party images and other materials added by Frontiers, which are subject to copyright of their respective owners. Authors are therefore free to disseminate and re-publish their articles, subject to any requirements of third-party copyright owners and subject to the original publication being fully cited. The ability to copy, download, forward or otherwise distribute any materials is always subject to any copyright notices displayed. Copyright notices must be displayed prominently and may not be obliterated, deleted or hidden, totally or partially.
Each Frontiers article strives for the highest quality, thanks to genuinely collaborative interactions between authors, editors and reviewers, who include many of the world's best scientists and scholars. Frontiers is well aware of the potential impact of published research both on future research and on society and, hence, does not support superficial review, light review or no-review publishing models. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public - and shape society. Therefore, Frontiers only applies the most rigorous and unbiased reviews, established in the high standards of the Frontiers Review System. Furthermore, only the top certified research, evaluated objectively through quantitative online article level metrics, is disseminated to increasingly wider communities as it gradually climbs the tiers of the Frontiers Tiering System from specialized expert readership towards public understanding.
Frontiers has a number of procedures in place to support and ensure the quality of the research articles that are published:
Only leading experts and established members of the research community are appointed to the Frontiers Editorial Boards. Chief Editors, Associate Editors and Review Editors are all listed with their names and affiliations on the Journal pages and are encouraged to publicly list their publication credentials.
Associate Editors oversee the peer-review and take the final acceptance decision on manuscripts. Editorial decision power is distributed in Frontiers, because we believe that many experts within a community should be able to shape the direction of science for the benefit of society.
Submitting authors can choose a preferred Associate Editor to handle their manuscript, because they can judge well who would be an appropriate expert in editing their manuscript. There is no guarantee for this preference of choice, Associate Editors can decline invitations any time, and the handling Associate Editor can also be over-ridden by the Chief Editor before she/he is invited to edit the article or at any other stage.
Associate Editors are mandated to only accept to edit a manuscript if they have no conflicts of interest (as stated here and in their review invitation and assignment emails).
Should it become clear that the Associate Editor has a conflict of interest or is unable to perform the peer-review timely and adequately, a new Associate Editor can be assigned to the manuscript by the Chief Editor, who has full control to intervene in the peer-review process at any time.
The Associate Editor initially checks that the article meets basic quality standards and has no obvious objective errors.
The Associate Editor can then personally choose and invite the most appropriate reviewers to handle the peer-review of the manuscript, including Review Editors from the board or external reviewers.
The Associate Editor is aided in this by the Frontiers Collaborative Review Forum software and interface, which suggests the most relevant Review Editors based on a match between their expertise and the topic of the manuscript. Associate Editors can however choose any reviewer they deem adequate.
After a certain time frame and if no reviewers have in the meantime been assigned to the manuscript, the Frontiers platform and algorithmic safety-net steps in and invites the most appropriate Review Editors based on constantly updated and improved algorithms that match reviewer expertise with the submitted manuscript.
Review Editors and reviewers are mandated to only accept to review a manuscript if they have no conflicts of interest (as stated here and in their review invitation and assignment emails).
Frontiers algorithms are constantly fine-tuned to better match Review Editors with manuscripts, and additional checks are being coded into the platform, for example regarding conflicts of interest.
Should it become clear that a particular reviewer has a conflict of interest or is unable to perform the peer-review timely and adequately, he or she shall be replaced with an alternative reviewer by the Associate Editor or the Chief Editor, who will be alerted and has full control to intervene into the peer-review at any time.
In the Independent Review Stage the assigned reviewers perform an in-depth review of the article independently of each other to safeguard complete freedom of opinion.
The reviewers are aided by an online standardized review questionnaire – adopted to article types – with the goal to facilitate rigorous evaluation according to objective criteria and the Frontiers Review Guidelines.
The Associate Editor assesses the reviews and activates the “Interactive Review” – informing the authors of the extent of revisions that are required to address the reviewers’ comments, and starting the Interactive Discussion Forum where authors and also the reviewers get full access to all review reports.
Manuscript and review quality at this stage are enhanced by allowing authors and reviewers to discuss directly with each other in real-time until they reach consensus and a final version of the manuscript is endorsed by the reviewers.
Reviewer identity is protected at this stage to safeguard complete freedom of opinion.
Reviewers can recommend rejection at this stage if their requests to correct objective errors are not being met by the authors or if they deem the article overall of insufficient quality.
Should a dispute arise, authors or reviewers can trigger an arbitration and will alert the Associate Editor, who can assign more reviewers and/or bring the dispute to the attention of the Chief Editor. The Associate Editor can also weigh in on the discussion and is asked to mediate the process to ensure a constructive revision stage.
The decision to accept an article needs to be unanimous amongst all reviewers and the handling Associate Editor.
The names of the Associate Editor and reviewers are disclosed on published articles to encourage in depth and rigorous reviews, acknowledge work well done on the article and to bring transparency and accountability into peer-review.
Associate Editors can recommend the rejection of an article to the Chief Editor, who needs to check that the authors’ rights have been upheld during the peer-review process, and who can then ultimately reject the article if it is of insufficient quality, has objective errors or if the authors were unreasonably unwilling to address the points raised during the review.
Chief Editors can at any stage of the peer-review step in to comment on the review process, change assigned editors, assign themselves as a reviewer and even as the handling editor for the manuscript, and therefore have full authority and all the mechanisms to act independently in their online editorial office to ensure quality.
Only leading researchers acting as Associate Editors, who are not part of Frontiers staff, can make acceptance decisions based on reviews performed by external experts acting as Review Editors or reviewers. None have a financial incentive to accept articles, i.e. they are not paid for their role to act as Associate or Review Editors, and any award scheme is not linked to acceptances of manuscripts.
Chief Editors receive an honorarium if their specialty section or field reaches certain submission levels. However, this honorarium is based on the total number of submitted articles during a calendar year, and not the number of accepted articles. Therefore they also have no financial incentive to accept manuscripts.
The Frontiers platform enables post-publication commenting and discussions on papers and hence the possibility to critically evaluate articles even after the peer-review process.
Frontiers has a community retraction protocol in place to retract papers where serious concerns have been raised and validated by the community that warrant retraction, including ethical concerns, honest errors or scientific misconduct.
