Special Issue Information

Dear Colleagues, 

Venoms are rich cocktails of active peptides, proteins, and enzymes that are very commonly used by various species to capture their prey or defend themselves. In most cases, these toxic secretions from one organism are injected into the internals of another organism through a mechanical injury. The exploration of venoms and their selected components—resulting from decades of evolution—have revealed dozens of therapeutically active and promising drug candidates. This exploration has implied various technical approaches, among which proteomics, transcriptomics, and bioinformatics are today in pole position. In this Special Issue, we first want to highlight and demonstrate—once again and again if necessary—how valuable molecules issued from insects and arthropods venoms can be for new drug candidate discovery. Since insects and arthropods account for most species of eukaryotic life on Earth, it seems obvious to expect that the richness of their venom arsenal is far from being completely explored. Second, this Special Issue aims to promote innovative results from research conducted on “noncommon” species focusing on the venom role in species adaptation. We therefore expect authors to share complete and exciting evidence of valuable action of discovered or optimized molecules.

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. Life 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).

Morocco is known to harbor two of the world’s most dangerous scorpion species: the black Androctonus mauritanicus (Am) and the yellow Buthus occitanus (Bo), responsible for 83% and 14% of severe envenomation cases, respectively. Scorpion venom is a mixture of biological molecules of variable structures and activities, most of which are proteins of low molecular weights referred to as toxins. In addition to toxins, scorpion venoms also contain biogenic amines, polyamines, and enzymes. With the aim of investigating the composition of the Am and Bo venoms, we conducted an analysis of the venoms by mass spectrometry (ESI-MS) after separation by reversed-phase HPLC chromatography. Results from a total of 19 fractions obtained for the Am venom versus 22 fractions for the Bo venom allowed the identification of approximately 410 and 252 molecular masses, respectively. In both venoms, the most abundant toxins were found to range between 2–5 kDa and 6–8 kDa. This proteomic analysis not only allowed the drawing of an extensive mass fingerprint of the Androctonus mauritanicus and Buthus occitanus venoms but also provided a better insight into the nature of their toxins.
