Special Issue Information

Dear Colleagues,

Acute and chronic pain are two major reasons that patients seek healthcare. Approximately 20% of the world’s population suffers from chronic pain, and in the USA alone, annual economic losses due to chronic pain are estimated to be USD 600 billion. Apart from being a major economic burden for society, chronic pain is also a major cause of decreased quality of life.

Chronic pain is often difficult to treat, and we have few objective measures for evaluating pain levels. Patients in pain therefore often struggle to have their pain problems acknowledged, as pain is a subjective experience that is difficult to verify. During the last decade, biomarkers related to chronic pain have been investigated. The discovery of such markers could not only be used to improve the diagnoses and prognostication of patients with chronic pain, but could also support those who file an insurance claim after an injury. Biomarkers of pain could also be used to distinguish different causes of pain, allowing for an improved selection of treatments. Such markers could also provide pharmaceutical companies with a tool for evaluating pain relief effects in clinical trials.

The focus of this Special Issue of Biomedicines is on the value of biomarkers of pain from a broad perspective.

Biomarkers of pain may be used to identify and quantify pain of various origins in order to facilitate adequate therapeutic interventions. Extensive prescriptions of analgesics, especially opioids, are associated with overdose deaths. Although pain is a subjective experience, the use of determinants of pain as an end point in clinical trials may help to predict the safety as well as the analgesic efficacy of new drugs.

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. Biomedicines 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 2600 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.

Neuropathic pain, a chronic condition arising from injury or dysfunction of the somatosensory nervous system, is characterized by persistent hypersensitivity and spontaneous pain. The chemokine receptor CCR5 (C-C motif chemokine receptor 5) has recently been identified as a critical mediator in neuroinflammation and neuropathic pain signaling pathways. Expressed on immune cells and neurons, CCR5 regulates immune cell recruitment and activation, thereby contributing to neuronal sensitization and maintenance of pain states. This review examines the currently characterized molecular mechanisms through which CCR5 modulates neuropathic pain pathophysiology and assesses the potential of CCR5 antagonists as novel therapeutic agents for the management of chronic neuropathic pain. Understanding the involvement of CCR5 in pain modulation may facilitate the development of targeted treatments with improved efficacy and safety profiles. Full article
