Proteotoxins such as ricin, abrin, botulinum neurotoxins type A and B (BoNT/A, BoNT/B) and staphylococcal enterotoxin B (SEB) are regarded as potential biological warfare agents which could be used for bioterrorism attacks on the food chain. In this study we used a novel immunisation strategy to generate high-affinity monoclonal and polyclonal antibodies against native ricin, BoNT/A, and BoNT/B...
In vivo and in vitro sublethal exposure of abrin, glycyrrhizin (active component of Abrus precatorius seed and root), sanguinarine, protopine (Argemone mexicana seed) and oleandrin (Nerium indicum leaf) inhibited the acetylcholinesterase, lactic dehydrogenase, acid and alkaline phosphatase activity in the nervous tissue of Lymnaea acuminata. The succinic dehydrogenase activity in the nervous ti...
A toxin from mistletoe, viscumin, inhibited the incorporation of leucine in cells more rapidly than the incorporation of uridine and thymidine, indicating that the toxins act by inhibiting cellular protein synthesis. The presence of galactose, lactose, and melibiose in the medium protected cells against viscumin. The sensitivity to viscumin of different cell lines differed considerably. The cyt...
