Special Issue Information

Dear Colleagues,

Since its discovery three decades ago, a considerable amount of research has focused on the effects of leptin in terms of weight control, glucose metabolism and overall homeostasis. This adipokine secreted by white adipocytes crosses the blood–brain barrier, and its main functions are on the arcuate nucleus of the hypothalamus where it controls appetite.

Even though it became quickly evident that exogenous administration of leptin does not represent the holy grail in the treatment of obesity, important recent insight shows that relatively high leptin levels are independently associated with insulin resistance; thus, attempts to decrease leptin levels—even in subjects without obesity—may still be beneficial. Translational studies combining clinical longitudinal data and adipose tissue (AT) biopsies to assess AT morphology and function may provide better insight into the determinants of leptin secretion. Moreover, the cross-talk between adipose tissue and other key metabolic organs (such as the brain and the liver) may be partly mediated via leptin’s action. Functional imaging studies with the simultaneous assessment of leptin levels may assess the effects of leptin on tissue-specific metabolism.

For this Special Issue, we welcome original papers that increase our insight regarding the secretion and function of this key adipokine, as well as high-level reviews that summarize the current knowledge on the topic.

Manuscript Submission Information

Manuscripts should be submitted online at 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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). 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.
