Dear Colleagues,

In recent decades, increasing importance has been given to the study of molecules present in saliva as a tool for the study of several diseases. This is due, first, to the fact that saliva is a fluid that, in addition to having constituents produced by the different salivary glands, contains several molecules transported by the plasma, some of which are present in quantities proportional to their levels in the blood; secondly, saliva sampling has the advantage of being non-invasive, with its collection easily accepted by most individuals. This aspect is particularly advantageous for children, the elderly, and people in whom blood collection is difficult, because it can involve fear and pain. These two points, together with technological and analytical advances, have led to a large amount of research interest in working with this fluid from different perspectives and using molecular biomarkers present in saliva as interesting tools for the diagnosis and monitoring of human diseases.

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.
