Recent incidents in the United States and abroad have heightened concerns about the use of ricin toxin as a bioterrorism agent. In this study, we produced, using a robust plant-based platform, four chimeric toxin-neutralizing monoclonal antibodies that were then evaluated for the ability to passively protect mice from a lethal-dose ricin challenge. The most effective antibody, c-PB10, was further evaluated in mice as a therapeutic following ricin exposure by injection and inhalation.

Article Synopsis
  • Shiga-toxin-producing E. coli (STEC) are harmful bacteria that can cause severe illnesses like diarrhea and kidney failure, making quick detection crucial but difficult.
  • A new rapid test has been developed using synthetic DNA substrates that produce a fluorescent signal when cleaved by Shiga toxins, allowing for easier identification of STEC.
  • In testing 94 clinical strains, including various STEC serotypes, this assay proved effective for immediate detection of Shiga toxins, potentially enhancing outbreak response and treatment strategies.

Background: Ricin, a toxin extracted from the seeds of , is classified as a ribosome-inactivating protein. The A-subunit of ricin shows RNA -glycosidase activity that cleaves ribosomal RNA (rRNA) and exhibits toxicity by inhibiting protein synthesis and inducing vascular leak syndrome.

Methods: In this study, we created a truncated version of the previously developed R51 ricin vaccine (RTA 1-194 D75C Y80C) through in silico analysis.

Article Synopsis
  • Ricin is a highly toxic substance linked to bioterrorism, and while a vaccine (RiVax™) is in development, no effective treatments currently exist for ricin poisoning.
  • * Studies have shown that anti-ricin monoclonal antibodies (mAbs) show great potential for neutralizing ricin and protecting against its effects in animal models.
  • * One specific mAb, RicE5, demonstrated over 90% survival in mice after ricin exposure, even when administered 6 hours or, to a lesser extent, 24 hours post-exposure, suggesting strong therapeutic potential and long-term immunity.

Advances in immunotoxin engineering: precision therapeutic strategies in modern oncology.

Venom and Biotherapeutics Molecules Laboratory, Biotechnology Department, Biotechnology Research Center, Pasteur Institute of Iran, Tehran, Iran.

Article Synopsis
  • Immunotoxins (ITs) are targeted therapeutic agents used mainly in cancer treatment, combining a monoclonal antibody with a powerful cytotoxic agent like diphtheria toxin or ricin for selective cell killing.
  • The antibody binds to specific antigens on target cells, allowing the internalization of the IT, which then releases the cytotoxic agent to induce cell death while sparing healthy cells.
  • ITs can be produced through recombinant fusion or chemical conjugation, each method having its own benefits and drawbacks, and their promising applications extend beyond oncology to other diseases like inflammatory conditions and atherosclerosis.

Ricin is a toxic protein regarded as a potential chemical weapon for bioterrorism or criminal use. In the event of a ricin incident, rapid analytical methods are essential for ricin confirmation in a diversity of matrices, from environmental to human or food samples. Mass spectrometry-based methods provide specific toxin identification but require prior enrichment by antibodies to reach trace-level detection in matrices.
