Special Issue Information

Dear Colleagues,

Pain is a complex and fascinating physiological and pathological phenomenon that plays a critical role in human health and disease. Understanding the molecular mechanisms underlying pain is essential for developing effective therapeutic strategies. This Special Issue of the IJMS aims to explore the intricate molecular and cellular pathways involved in pain signaling, modulation, chronic pain development, and its relationship with other physiological aspects of health, including cognitive and emotional disturbances.

We invite submissions investigating the molecular basis of pain in various contexts, including acute and chronic pain conditions, neuropathic pain, orofacial pain, and pain associated with inflammatory and degenerative diseases. Manuscripts focusing on novel molecular targets, signaling pathways, epigenetic regulation, and interactions between the nervous and immune systems are particularly encouraged. Research and up-to-date reviews exploring cutting-edge therapeutic approaches, such as pharmacogenomics, gene editing, molecular inhibitors, and nanotechnology-based drug delivery systems, are also of significant interest.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Pain management in children remains a challenge. Postoperative pain assessment, which currently relies on behavioral and subjective scales, could be enhanced by the identification of single nucleotide polymorphisms effect on pain thresholds and opioid metabolism. This study explores the impact of nine SNPs—rs1799971, rs4680, rs4633, rs6269, rs4818 (with catechol-o-methyltransferase haplotypes), rs7832704, rs1801253, and rs1045642—on postoperative pain intensity, opioid requirements, coanalgesic use, C-reactive protein levels, and post-anesthesia care unit length of stay. This study involved 42 pediatric patients undergoing scoliosis correction surgery with postoperative sufentanil infusion. The genotyping was performed using real-time PCR with peripheral blood samples. Patients with the rs1801253 ADRB1 GG genotype showed significantly lower 24 h NRS pain ratings (p = 0.032) and lower sufentanil infusion rates at the level of statistical tendency (p = 0.093). Patients with the rs1205 CRP CT genotype had a shorter PACU length of stay (p = 0.012). In contrast, those with the rs1045642 ABCB1 GG genotype had a longer PACU stay by 0.72 h (p = 0.046). No significant associations were found for OPRM1 rs1799971, COMT, or ENPP2 SNPs. ADRB1 rs1801253may be a novel SNP indicating higher postoperative pain risk, while rs1205 CRP and rs1045642 ABCB1 could predict increased care requirements in PACUs. The ADRB1 rs1801253 SNP may also predict opioid demand. These results suggest SNPs should be considered in acute pain assessment. Full article
