Ricin Toxicity: Clinical and Molecular Aspects
Seeds of the castor bean plant Ricinuscommunis L (CB) contain ricin toxin (RT), one of the most poisonous naturally-occurring substances known. Ricin toxin, a water-soluble glycoprotein that does not partition into the oil extract, is a ribosome-inactivating toxin composed of two chains, labeled A and B. Severity of the toxicity varies depending on the route of exposure to the toxin. Inhalation...
متن کاملInactivation of Ricin Toxin by Nanosecond Pulsed Electric Fields Including Evidences from Cell and Animal Toxicity
Ricin is one of the most toxic and easily produced plant protein toxin extracted from the castor oil plant, and it has been classified as a chemical warfare agent. Here, nanosecond pulsed electric fields (nsPEFs) at 30 kV/cm (pulse durations: 10 ns, 100 ns, and 300 ns) were applied to inactivating ricin up to 4.2 μg/mL. To investigate the efficacy, cells and mice were tested against the ricin t...
متن کاملKinetic analysis of choriocarcinoma cell intoxication induced by ricin and ricin A chain immunotoxin.
The kinetics of protein synthesis inhibition was studied in the choriocarcinoma-derived BeWo cell line treated with ricin and an immunotoxin (IT) constructed by linking a specific antibody to the A chain of ricin. The IT was specifically cytotoxic to BeWo and other choriocarcinoma cells. The multistep process underlying this kinetics was explored using two mathematical models where the protein ...
