Special Issue Information
Dear Colleagues,
Neuropathic pain is pain resulting from a lesion or disease of the somatosensory nervous system. It is often triggered by trauma of the peripheral (e.g., peripheral nerve injury) or central nervous system (e.g., spinal cord injury), but it can result from non-traumatic pathologies (e.g., diabetes, cancer, and neurodegenerative diseases). Moreover, neuropathic pain can also arise after specific treatments, including the use of chemotherapy agents or after heavy surgeries.
While traditionally neuropathic pain has been seen and targeted as neuronal dysregulation, accumulating evidence shows that glial cells, most prominently microglia and astrocytes, are pivotal in the establishment and maintenance of neuropathic pain. When activated by peripheral and/or central insults, microglia and astrocytes can disrupt the balance between pro-inflammatory and anti-inflammatory mediators, leading to persistent neuroinflammation and sensitization of pain pathways. This sustained inflammatory environment is highly deleterious and may lead to aberrant pain processing and resistance to conventional analgesics. Importantly, once set in motion, abnormal and unbalanced activity of astrocytes and microglia will likely operate in a positive feedback manner, perpetuating neuropathic pain. Therefore, insights into atypical activity of glial cells offer opportunities for a better understanding of the pathophysiology of neuropathic pain and will contribute to the development of novel pharmacological and non-pharmacological approaches.
This Special Issue aims to deliver the most recent information about mechanisms of neuropathic pain and novel strategies to modulate glial cells in all dimensions (sensory, affective, and emotional) of neuropathic pain. Studies may include original experimental and review articles from animal research to translational and clinical studies.

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. Biomolecules is an international peer-reviewed open access monthly 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.
