Special Issue Information

Dear Colleagues,

Pain is defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” Chronic pain, lasting for more than three months, represents one of the main worldwide problems, in term of social and economic resources, causing severe and intractable physical and psychological suffering. The lack of specific biomarkers is a great limitation in pain medicine, because it does not allow a precise diagnosis and appropriate treatments. Unequivocal markers are urgently needed to bypass sensory–discriminative, affective–motivational, and cognitive–evaluative pain limits. Several studies have presented pain as the result of the synergy between immune and nervous systems. The crucial link is the evidence that opioid peptides and their receptors are expressed both in the nervous system and the immune cell surface. However, the function of opioid receptors in the immune system cells, when and why are activated, and what their relation is with pain are still topics of discussion. Recent evidence on different chronic pain diseases (e.g., osteoarthritis and fibromyalgia) describes common characteristics in the expression of opioid receptors in diverse levels of pain.

In light of this, it is essential that we build a holistic understanding of the relation between pain and immune pathways, focusing on the common elements between the two systems, in order to detect pain biomarkers, improve diagnosis, and propose new clinical approaches.

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. Diagnostics is an international peer-reviewed open access semimonthly 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 2600 CHF (Swiss Francs).
