Special Issue Information
Dear Colleagues,
Dyslipemia and metabolic syndrome are considered established risk factors for cardiovascular diseases. The metabolic syndrome dyslipidemia is characterized by high levels of triglycerides and apolipoprotein (apo) B-100-rich particles of a particularly atherogenic phenotype (small dense low-density lipoprotein-cholesterol (LDL-C)), and low levels of high-density lipoprotein-cholesterol (HDL-C). One of the common phenotypic characteristics that define the impact of dyslipidemia and metabolic syndrome on the heart is the accumulation of lipids in the form of lipid droplets into the cardiomyocytes. There are different mechanisms involved in this pathophysiological mechanism, ranging from alterations in fatty acid uptake and oxidation caused by impaired insulin signaling, to alterations in the lipoprotein profile and lipoprotein receptors involved in lipid uptake. Signal pathways modulating autophagy, and in particular lipophagy, play an essential role in cardiac dysfunction associated with dyslipemia and metabolic syndrome. An intense debate exists about the pro- or anti-inflammatory role of lipid droplets under specific circumstances. What it is clear is that the modulation of lipid droplet formation and lipid droplet composition offers key therapeutic opportunities to preserve cardiac functionality.

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 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. 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.
