Special Issue Information
Dear Colleagues,
Melanin pigments are produced by melanocytes located in the basal layer of the epidermis and transferred to keratinocytes. Melanin pigments are synthesized in specialized organelles within melanocytes, termed melanosomes. Melanosomes move along the cytoskeleton to the dendrites of melanocytes and are then transferred to surrounding keratinocytes, where they are processed and accumulate over the nucleus, forming supra-nuclear caps. Defective melanosome trafficking results in hyper- and hypo-pigmentary disorders such as melasma, age spots, Hermansky–Pudlak/Griscelli/Chediak–Higashi syndromes and vitiligo. Many studies have characterized the mechanisms of melanosome biogenesis and transport in melanocytes, but fewer have addressed the mechanisms of melanosome transfer to keratinocytes and further processing within these cells. Therefore, many unknown mechanisms remain to be clarified. Through the elucidation of these mechanisms, the development of novel therapeutic agents for pigmentary disorders is expected. In this Special Issue, reviews and original articles related to melanosome transport/transfer and melanin pigmentation, as well as research topics on the degradation/processing and polarization of melanin within keratinocytes, are welcome.

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.
