Special Issue Information

Dear Colleagues,

Natural substances have been of interest for several centuries, and many toxins of animal, plant, bacterial, or fungal origins have been identified and characterized. There is a long way to go, from finding venomous species in their natural habitat, through collecting their venom under strict safety and species preservation conditions, to the extraction of natural toxins in the laboratory. State-of-the-art technologies are making it possible to explore, as close as possible to their site of action, the functioning of these tools on a molecular level and to design some of them that will contribute to the development and progress of diagnostic medicine or therapeutics.

In this Special Issue of the journal Toxins, titled “Toxins: From the Wild to the Lab”, research and review articles concerning the latest discoveries in the field of venoms and toxinology will be presented to cover broad areas ranging from the composition and evolution of venoms to the mechanism of action, structural conservation versus variability, and therapeutic applicability of toxins. This Special Issue is open, albeit not restricted, to the communications that were presented during the 29th Meeting of Toxinology (RT29) organized by the French Society of Toxinology (SFET) on the 30th of November and 1st of December 2023 at the Institut Pasteur of Paris.

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.

Viper venom phospholipase A2 enzymes (vvPLA2s) and phospholipase A2-like (PLA2-like) proteins are two of the principal toxins in viper venom that are responsible for the severe myotoxic and neurotoxic effects caused by snakebite envenoming, among other pathologies. As snakebite envenoming is the deadliest neglected tropical disease, a complete understanding of these proteins’ properties and their mechanisms of action is urgently needed. Therefore, we created a database comprising information on the holo-form, cofactor-bound 3D structure of 217 vvPLA2 and PLA2-like proteins in their physiologic environment, as well as 79 membrane-bound viper species from 24 genera, which we have made available to the scientific community to accelerate the development of new anti-snakebite drugs. In addition, the analysis of the sequenced, 3D structure of the database proteins reveals essential aspects of the anatomy of the proteins, their toxicity mechanisms, and the conserved binding site areas that may anchor universal interspecific inhibitors. Moreover, it pinpoints hypotheses for the molecular origin of the myotoxicity of the PLA2-like proteins. Altogether, this study provides an understanding of the diversity of these toxins and how they are conserved, and it indicates how to develop broad, interspecies, efficient small-molecule inhibitors to target the toxin’s many mechanisms of action.
