Role of Insulin Secretion, Clearance and Action in Metabolic Diseases

Dear Colleagues, 

Metabolic diseases are reaching an epidemic worldwide. In addition to insulin resistance and impaired insulin action, altered insulin secretion and clearance contribute to the worsening of glucose and lipid metabolism. Upon its secretion from pancreatic beta cells, insulin is metabolized mostly by the liver (the first target organ), and subsequently, by peripheral tissues, in particular skeletal muscle. Thus, peripheral insulin concentrations are the result of a balance between insulin secretion and clearance. The mechanisms underlying insulin secretion and action have been widely explored. In contrast, mechanisms underlying insulin clearance remain poorly understood. This Special Issue focuses on presenting a comprehensive view on the regulation of insulin homeostasis with an overarching goal to highlight the current knowledge on the mechanisms as well as the physiologic impact of altered insulin secretion, clearance and action on metabolic processes.

We invite investigators to contribute either original research or review articles focusing on the variety of molecular mechanisms of altered insulin secretion, clearance and action, and their impact on insulin resistance and the pathogenesis of cardiometabolic diseases that include, but are not limited to, type 2 diabetes, non-alcoholic fatty liver disease (NAFLD/NASH), atherosclerosis, hypertension in animal models and in subjects with different degrees of glucose intolerance.  Special attention will be given to the effect of dietary or pharmacological interventions on insulin metabolism. Articles should also discuss how these mechanisms cause or contribute to the progression to type 2 diabetes and associated metabolic diseases, and how they are modulated by race, sex and environmental factors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
