Special Issue Information

Dear Colleagues,

Neuropathic pain is caused by a lesion or diseases affecting the somatosensory system (IASP). It affects around 7–8% of the general population and represent 25% of chronic pain patients. Despite the research in the last 30 years, only a few and relatively poorly efficient molecules have been found to treat neuropathic pain with a huge translational failure rate. Most of the preclinical models focused on sensory neurotransmission, with a special emphasize on the first relay of nociceptive information, the dorsal horn of the spinal cord. Beyond alterations to nociceptive transmission, neuropathic pain is also accompanied by many associated comorbidities such as anxio-depressive disorders, anhedonia, and motor and cognitive deficits, which reflect the “pain matrix”. The emergence of cutting-edge techniques assessing specific neuronal circuits facilitate in-depth studies of the connections between the pain matrix circuits and the behavioral outputs. Pain behaviors are evaluated through reflex-induced responses and various complex behaviors to obtain the most complete vision of the painful state. In the coming years, this will provide new, promising therapeutic strategies.

In this Special Issue, we invite you to improve our current knowledge of neuropathic pain by contributing original research articles. Stimulating reviews that critically appraise or provide new interpretations of the extant literature are also 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. 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.

Chronic pain is a pathological state defined as daily pain sensation over three consecutive months. It affects up to 30% of the general population. Although significant research efforts have been made in the past 30 years, only a few and relatively low effective molecules have emerged to treat chronic pain, with a considerable translational failure rate. Most preclinical models have focused on sensory neurotransmission, with particular emphasis on the dorsal horn of the spinal cord as the first relay of nociceptive information. Beyond impaired nociceptive transmission, chronic pain is also accompanied by numerous comorbidities, such as anxiety–depressive disorders, anhedonia and motor and cognitive deficits gathered under the term “pain matrix”. The emergence of cutting-edge techniques assessing specific neuronal circuits allow in-depth studies of the connections between “pain matrix” circuits and behavioural outputs. Pain behaviours are assessed not only by reflex-induced responses but also by various or more complex behaviours in order to obtain the most complete picture of an animal’s pain state. This review summarises the latest findings on pain modulation by brain component of the pain matrix and proposes new opportunities to unravel the mechanisms of chronic pain. Full article
