Autor: Nicolas Gilles, Da-Cheng Wang, Marcel Pelhate, Yu-Mei Xiong, Maria Stankiewicz, Cheng-Wu Chi, Chunguang Wang, Alain Hamon, Frédéric Le Gall
Publikováno v: Biochemistry. 42:4699-4708
Scorpion alpha-neurotoxins can be classified into distinct subgroups according to their sequence and pharmacological properties. Using toxicity tests, binding studies, and electrophysiological recordings, BmK M1, a toxin from the Asian scorpion Buthu

Scorpion alpha-toxins from Leiurus quinquestriatus hebraeus, LqhII and LqhIII, are similarly toxic to mice when administered by a subcutaneous route, but in mouse brain LqhII is 25-fold more toxic. Examination of the two toxins effects in central ner

Publikováno v: European Journal of Neuroscience. 11:3134-3142
A novel conotoxin was isolated and characterized from the venom of the fish-hunting marine snail Conus consors. The peptide was identified by screening chromatography fractions of the crude venom that produced a marked contraction and extension of th

The strategy used by some piscivorous cone snails to capture their prey: the effects of their venoms on vertebrates and on isolated neuromuscular preparations
Autor: Philippe Favreau, Yves Letourneux, Georges Richard, Frédéric Le Gall, Jordi Molgó
Publikováno v: Toxicon. 37:985-998
Three piscivorous Conus species, C. ermineus, C. consor and C. catus were acclimatized in aquaria. The study of their strategy to capture the prey and details of their radula's morphology revealed that all of them used a 'hook and line' strategy whic

We have isolated delta-conotoxin EVIA (delta-EVIA), a conopeptide in Conus ermineus venom that contains 32 amino acid residues and a six-cysteine/four-loop framework similar to that of previously described omega-, delta-, microO-, and kappa-conotoxin

Benthic dinoflagellates of the genus Prorocentrum are common in tropical and subtropical water and several species produce phycotoxins potentially involved in human toxic outbreaks. The toxic dinoflagellate Prorocentrum borbonicum collected at La Reu
