A nontoxigenic form of Shiga toxin 2 suppresses the production of amyloid β by altering the intracellular transport of amyloid precursor protein through its receptor-binding B-subunit.

Abstract excerpt

Accumulation of amyloid-β peptide (Aβ) in neuronal cells and in the extracellular regions in the brain is a major cause of Alzheimer's disease (AD); therefore, inhibition of Aβ accumulation offers a promising approach for therapeutic strategies against AD. Aβ is produced by sequential proteolysis of amyloid precursor protein (APP) in late/recycling endosomes after endocytosis of APP located in the plasma...
