Active Shiga-like toxin produced by some Aeromonas spp., isolated in Mexico City
Shiga-like toxins (Stx) represent a group of bacterial toxins involved in human and animal diseases. Stx is produced by enterohemorrhagic Escherichia coli, Shigella dysenteriae type 1, Citrobacter freundii and Aeromonas spp.

Tamoxifen blocks retrograde trafficking of Shiga toxin 1 and 2 and protects against lethal toxicosis
This study reports an unexpected role of late endosome–lysosome fusion in early endosome-to-Golgi trafficking of Shiga toxins and identifies tamoxifen to be a potent inhibitor of Shiga toxicosis. Shiga toxin 1 (STx1) and 2 (STx2), produced by Shiga toxin–

Retrograde transport pathways utilised by viruses and protein toxins
A model has been presented for retrograde transport of certain toxins and viruses from the cell surface to the ER that suggests an obligatory interaction with a glycolipid receptor at the cell surface. Here we review studies on the ER trafficking cholera

Mutational analysis of the Shiga toxin and Shiga-like toxin II enzymatic subunits [PDF]
The A-subunit polypeptides of Shiga toxin, the Shiga-like toxins (SLTs), and the plant lectin ricin inactivate eucaryotic ribosomes by enzymatically depurinating 28S rRNA. Comparison of the amino acid sequences of the members of the Shiga toxin family and ricin revealed two regions of significant homology that lie within a proposed active-site cleft of

Rapid and Label-Free Immunosensing of Shiga Toxin Subtypes with Surface Plasmon Resonance Imaging
Shiga toxin-producing Escherichia coli (STEC) are responsible for gastrointestinal diseases reported in numerous outbreaks around the world as well as in the United States. Current detection methods have limitation to implement for rapid field-deployable

PREPARATION AND PROPERTIES OF SHIGA TOXIN AND TOXOID [PDF]
1. Shigella dysenteriae (Shiga) can, under the proper cultural conditions, produce a soluble toxin which is independent of the specific somatic polysaccharide antigen. A method is described for the rapid production of this toxin by an avirulent R variant of this organism. 2.

A 310‐helix‐mediated conformational switch promotes a front‐face SNi‐like catalysis by human A4GALT. Mechanism‐guided design identifies AdaGalCer as a selective modulator of globotriaosylceramide (Gb3) biosynthesis, opening a clear route toward new Fabry disease therapeutics.

Epithelial cell signaling responses to enterohemorrhagic Escherichia coli infection
Enterohemorrhagic Escherichia coli, including the serotype O157:H7 that is most commonly identified with human disease, cause both sporadic cases and outbreaks of non-bloody diarrhea and hemorrhagic colitis.

Shiga toxins (Stx) are cytotoxins involved in severe human intestinal disease. These toxins are commonly found in Shigella dysenteriae serotype 1 and Shiga-toxin–producing Escherichia coli; however, the toxin genes have been found in other Shigella ...
