Special Issue Information

Dear Colleagues,

Botulinum neurotoxins (BoNTs) have become a well-established treatment option in a wide range of excessive muscle contractility disorders and as such have been routinely used since decades to treat cervical dystonia, spastic conditions, blepharospasm, hyperhidrosis, and for cosmetic purposes. BoNTs are categorized into seven toxinotypes, two of which are in clinical use, with each toxinotype being divided into multiple subtypes. With the development of bioinformatic tools, new BoNT-like toxins have been identified in non-Clostridial organisms, in addition to the expanding indications of existing formulations. The increased understanding of their molecular biology as well as the design of recombinant BoNT form the basis to develop innovative BoNT-based therapeutics as well as research tools. An overview of the diverse mechanisms of action of the BoNT family along with their impact on the nociceptive pathways, through its central and peripheral activities, the molecular mechanisms of action in neurons, and general pharmacokinetic parameters are presented in this Special Issue providing a broader understanding of its actions. This Special Issue will allow the advanced understanding of their therapeutic potential in acute and chronic pain, while further experimental and clinical research is still required to validate the mechanisms of action experimentally.

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 double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins 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.

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.
