Special Issue Information
Dear Colleagues,
The physiological perception of pain is essential for the brain to engage appropriate responses against noxious stimuli. In pathological conditions, such as chronicity, pain lacks the positive characteristic of alarm evolving to disease. Based on three major characteristics, namely symptoms, mechanisms and syndromes, pain may be classified into three classes: nociceptive, neuropathic, and inflammatory pain. The events that follow one another leading to the onset of pain can originate from various sources and consist of three events: the transduction, transmission and modulation of noxious stimuli.
The cell type most involved in the various phases of pain projection are the sensory neurons whose sensitivity can be modulated by various mediators. The latter trigger the activation of many different signaling cascades, which, in turn, determine the response to painful stimuli.
Although many studies have shed light on some components of the intracellular signal transduction cascades, the signaling pathways downstream of receptor–ligand interactions are still largely unknown.
Another very important aspect to consider is the plethora of plastic changes that take place in the peripheral and the central nervous systems to contribute to pain perception. In addition, the molecular mechanism responsible for neuronal and glial plasticity is widely accepted as the mechanism underpinning the transition from acute/physiological pain to chronic/pathological pain.
Thus, understanding the molecular and cellular mechanisms of pain is essential for the advance of pain physiopathology knowledge for the identification of new therapeutic targets and, finally, to improve its management.

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. Cells 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 2700 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.
