Special Issue Information
Dear Colleagues,
Angiogenesis is the process by which new blood capillaries form from pre-existing vessels, which occurs in reproduction, growth, and development. Angiogenesis has been implicated, directly or indirectly, in many disorders, among them being cancer, autoimmune diseases, diabetic retinopathy, rheumatoid arthritis, and atherosclerosis. Conversely, insufficient vascularization underlies conditions such as stroke, coronary heart disease, and delayed wound healing, where inadequate blood vessel growth leads to poor circulation and tissue death.
Recent findings have illuminated that angiogenesis is a prominent feature of neurological diseases, either as a pathophysiological factor or as a response to injury. The presence of microvascular changes with decreased density and structural abnormalities has been well documented both in brain aging and neurodegenerative diseases. Most cases of Alzheimer’s disease are accompanied by cerebrovascular pathologies, such as cerebral amyloid angiopathy, endothelial degeneration, white matter lesions, cerebral haemorrhages, and blood–brain barrier dysfunctions. Different vascular risk factors linked to cerebrovascular diseases and stroke, such as hypertension, atherosclerosis, diabetes mellitus, and cardiac disease, are known to significantly increase the risk of developing neurodegenerative diseases.
Angiogenesis is a dynamic and complex process regulated by a very sensitive interplay of endogenous growth factors and inhibitors, and their imbalance can lead to disease.
Metal ions play a pivotal role in different steps of angiogenic processes. They may result also in being “pathogenic”, and their mishandling in cells can be associated with multiple diseases. In particular, copper is well known to be an essential angiogenesis cofactor in vivo, and plays a key role in neurodegeneration, together with zinc and iron.
Serum metal ion levels are raised in a wide variety of human cancers, and correlate with the tumour severity. Calcium, magnesium, and zinc may promote metastasis by facilitating angiogenesis.
So far, the specific molecular mechanism of the various metal ions’ involvement and activity targets remain unclear or not fully explored.
This Issue focuses on the biological inorganic chemistry of metal ions in all features of angiogenesis. It aims for a molecular understanding of the functional roles of metals in promoting or inhibiting angiogenesis in wealthy and pathogenic disease states. This research topic covers also the potential application of metal ions in wound healing and tissue regeneration, as well as the analytical determination of metal ions in all steps of vascular formation.

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.
