L. Johannes et B. Goud, SURFING ON A RETROGRADE WAVE - HOW DOES SHIGA TOXIN REACH THE ENDOPLASMIC-RETICULUM, Trends in cell biology, 8(4), 1998, pp. 158-162
Bacterial Shiga toxin and related toxins are endocytosed by higher euk
aryotic cells. Tile toxin protein is then transported via the Golgi ap
paratus to tile endoplasmic reticulum (ER) and into the cytosol, where
it exerts its toxic effect. This review discusses current understandi
ng of this retrograde transport pathway and how newly developed modifi
ed toxins that allow detection and quantification of specific transpor
t steps might prove useful teals in the future.
