Iron is the second most abundant metal and the fourth most abundant element of the earth’s crust. It is essential for numerous biochemical processes of almost every organism, such as oxygen sensing and transport, electron transfer, and catalysis. Therefore, adequate iron supply is critical for cellular as well as organismal homeostasis. Although iron deficiency leads to various biochemical disorders, iron excess is potentially toxic as it can generate reactive oxygen species (ROS) via Fenton reactions. Organisms of different orders have thus developed customized iron metabolism of their own which has to be tightly regulated. Regular and sufficient intake of iron through diet is critical for efficient hemoglobin synthesis in the mammals. In humans, iron imbalance constitutes a major global health burden, as both deficiency (mainly nutritional) and overload (genetically encoded) disorders are prevalent in distinct geographical and genetic backgrounds. In addition, dysregulated iron metabolism has been implicated in various disorders, such as inflammation, infection, and cancer highlighting its much broader role in pathophysiology. Over recent years, discovery of several new players in cellular and systemic iron regulation has revolutionized our understandings from both basic science and translational perspectives. For example, novel roles of host-gut microbiota crosstalk in mammalian iron homeostasis, and its connection with cell proliferation and metabolism have generated widespread interest. Many questions still remain unanswered with regard to the organellar dynamics of iron in cellular physiology, for which ongoing studies and relentless efforts are currently under way.

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. Pathophysiology is an international peer-reviewed open access quarterly 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 1400 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.
