Development of a Graphene Oxide-Based Aptamer Nanoarray for Improved Neutralization and Protection Effects Against Ricin [PDF]
PharmaceuticsBackground/Objectives: Ricin’s high toxicity and potential as a bioweapon underscore the need for effective antidotes. Monoclonal antibodies, though effective, are limited by complex production.

Ricin as a Biothreat Agent: From Molecular Mechanisms to Clinical Toxicology, Forensic Aspects, and Risk Mitigation. [PDF]
Biomed Res IntRicin, a potent ribosome‐inactivating protein derived from the seeds of Ricinus communis L., represents a significant threat in the context of biological warfare and terrorism due to its high toxicity, ease of extraction, and lack of a specific antidote.

Purified Immunoglobulin F(ab′) 2 Protects Mice and Rhesus Monkeys against Lethal Ricin Intoxication
Zoonoses, 2023 Ricin is a highly toxic ribosome-inactivating lectin derived from castor beans. To date, no antidote is available to treat ricin-poisoned patients, and the development of a safe and effective antidote is urgently needed.

Ricin trafficking in plant and mammalian cells [PDF]
, 2011 Ricin is a heterodimeric plant protein that is potently toxic to mammalian and many other eukaryotic cells. It is synthesized and stored in the endosperm cells of maturing Ricinus communis seeds (castor beans).

RNAi screening of Drosophila (Sophophora) melanogaster S2 cells for ricin sensitivity and resistance [PDF]
, 2011 The ribosome-inhibiting toxin ricin binds exposed β1→4 linked galactosyls on multiple glycolipids and glycoproteins on the cell surface of most eukaryotic cells. After endocytosis, internal cell trafficking is promiscuous, with only a small proportion of

The isolation and characterisation of temperature-dependent Ricin A chain molecules in Saccharomyces cerevisiae. [PDF]
, 2007 Ricin is a heterodimeric plant protein that is potently toxic to mammalian cells. Toxicity results from the catalytic depurination of eukaryotic ribosomes by ricin A chain (RTA) that follows toxin endocytosis to, and translocation across, the ...

The proteasome cap RPT5/Rpt5p subunit prevents aggregation of unfolded ricin A chain [PDF]
, 2013 The plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the endoplasmic reticulum (ER) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and ...

The Possible Protective Effect of Alpha-Lipoic Acid against Acute Ricin-Induced Nephrotoxicity in Adult Male Albino Rats [PDF]
Ain Shams Journal of Forensic Medicine and Clinical Toxicology, 2018 Background: Ricin toxin is considered one of the most potent plant-derived toxins. It induces rapid and irreversible toxic effects through many mechanisms with special concern to inhibition of protein synthesis and oxidative stress resulting in cell ...

Characterization of Ricin and R. communis Agglutinin Reference Materials
Toxins, 2015 Ricinus communis intoxications have been known for centuries and were attributed to the toxic protein ricin. Due to its toxicity, availability, ease of preparation, and the lack of medical countermeasures, ricin attracted interest as a potential ...
