Toxicon, 2011
Muscarinic toxins isolated from the venom of Dendroaspis snakes may interact with a high affinity, large selectivity and various functional properties with muscarinic receptors. Therefore, these toxins are invaluable tools for studying the physiological role, molecular functioning and structural organization of the five subtypes of these G-Protein ...

Trends in Microbiology, 2001
Researchers from Harvard Medical School have identified mutants of the anthrax toxin that could be used in the development of a therapeutic vaccine, as reported in Science. Rats injected with mutant protective antigen and a normally lethal dose of the anthrax toxin survived, suggesting that the mutant antigen could be useful as both a vaccine and an ...

Hormone, lectin and toxin-toxin conjugates
1988In order to better understand the relative importance of the A and B chains of diphtheria toxin and ricin, chimeras or hybrid toxins have been constructed with diphtheria toxin subunits and ricin subunits coupled to a number of different binding moieties.

Cyanobacterial toxins and toxin production
Phycologia, 1996Abstract Several cyanobacteria species commonly forming mass occurrences (blooms) in fresh, brackish and marine waters produce toxins. They have caused death of animals all over the world and may be a health hazard for humans. The toxins are classified, according to the target of their toxic action, as hepatotoxins, neurotoxins and dermatotoxins.

Molecular Nutrition & Food Research, 2006
AbstractBlue‐green algae are found in lakes, ponds, rivers and brackish waters throughout the world. In case of excessive growth such as bloom formation, these bacteria can produce inherent toxins in quantities causing toxicity in mammals, including humans. These cyanotoxins include cyclic peptides and alkaloids.

Epsilon toxin: a fascinating pore‐forming toxin
The FEBS Journal, 2011Epsilon toxin (ETX) is produced by strains of Clostridium perfringens classified as type B or type D. ETX belongs to the heptameric β‐pore‐forming toxins including aerolysin and Clostridium septicum alpha toxin, which are characterized by the formation of a pore through the plasma membrane of eukaryotic cells consisting in a β‐barrel of 14 amphipatic β

Detoxification of a bacterial toxin by the toxin itself
Trends in Pharmacological Sciences, 2001Abstract Several bacterial protein toxins act by forming oligomers on the cell surface. A novel approach to the prevention of the damage caused by oligomeric pore-forming toxins has recently been discovered using one such protein: the protective antigen (PA) of Bacillus anthracis .

Clinical Reviews in Allergy, 1993
We have presented in some detail the more common clinical syndromes produced by the ingestion of natural seafood toxins, and touched on those that could be of interest to the international traveler and to the sport fisherman. For the practicing allergist, knowledge of this wide array of clinical syndromes of toxicity is of paramount importance for the ...

Scientific American, 1994
On May 2, 1878, George Francis of Adelaide, Australia, published the Þrst scholarly description of the potentially lethal eÝects produced by cyanobacteriaNthe microorganisms sometimes called blue-green algae or, more colloquially, pond scum. In a letter to Nature he noted that an alga he thought to be Nodularia spumigena had so proliferated in the ...
