Special Issue Information
Dear Colleagues,
Ribosome-inactivating proteins (RIPs) cause the inactivation of ribosomes by linking adenine 4324 to the ribosome–phosphate backbone of the 28 rRNA of the large ribosome subunit, leading to hydrolysis of the N-glycosidic bond and the subsequent arrest of protein synthesis. Other enzymatic activities of RIPs such as polynucleotide adenosine glycosidase on nucleic acids have also been described. Most RIPs are of plant origin, where a protective role against predators and pathogens has been proposed, a progressive decrease in RIPs occurring in the fruits along ripening and in the leaves as these become senescent. Some other RIPs have been extracted from bacteria, fungi and algae.
Some two-chain (type 2) RIPs display high toxicity, such as ricin, and due to the wide use of plants as food and in folk medicine, the presence of these proteins should be a cause of concern. Nonetheless, its toxicity, together with the lectin activity and the possibility of preparing conjugates and immunotoxins could serve as drugs in targeted therapy, especially with less toxic native RIPs.
Despite a number of excellent and significant reviews being published in recent years, the latest research on RIPs has prompted us to propose a Special Issue covering the diverse aspects of these proteins, the actual biological roles of which are still unknown. This Special Issue will address the topics of new proteins and recombinant forms, their structure, intracellular traffic and toxicity. The coverage will also include the effects of RIPs as poison and their concomitant use as bioweapons, as contaminants of food, their clinical incidence, analytical procedures for their detection and their application for the preparation of conjugates and immunotoxins useful for targeted therapy, also considering their limitations.
Hence, this Special Issue of Toxins is open for the submission of both descriptive and experimental articles on this topic, to highlight the importance of this increasingly impactful subject. We encourage researchers to participate by submitting articles dealing with the field.
Sincerely,
Prof. Dr. Manuel Garrosa

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.
