Geldanamycin Enhances Retrograde Transport of Shiga Toxin in HEp-2 Cells
The heat shock protein 90 (Hsp90) inhibitor geldanamycin (GA) has been shown to alter endosomal sorting, diverting cargo destined for the recycling pathway into the lysosomal pathway. Here we investigated whether GA also affects the sorting of cargo into the retrograde pathway from endosomes to the Golgi apparatus. As a model cargo we used the bacterial toxin Shiga toxin, which exploits the ret...
متن کاملShiga toxin facilitates its retrograde transport by modifying microtubule dynamics.
The bacterial exotoxin Shiga toxin is endocytosed by mammalian host cells and transported retrogradely through the secretory pathway before entering the cytosol. Shiga toxin also increases the levels of microfilaments and microtubules (MTs) upon binding to the cell surface. The purpose for this alteration in cytoskeletal dynamics is unknown. We have investigated whether Shiga toxin-induced chan...
متن کاملRetrograde transport is not required for cytosolic translocation of the B-subunit of Shiga toxin.
Antigen-presenting cells have the remarkable capacity to transfer exogenous antigens to the cytosol for processing by proteasomes and subsequent presentation on major histocompatibility complex class-I (MHC-I) molecules, a process termed cross-presentation. This is the target of biomedical approaches that aim to trigger a therapeutic immune response. The receptor-binding B-subunit of Shiga toxi...

متن کاملInduction by sphingomyelinase of shiga toxin receptor and shiga toxin 2 sensitivity in human microvascular endothelial cells.
Shiga toxin-producing enterohemorrhagic Escherichia coli is the major cause of acute renal failure in young children. The interaction of Shiga toxins 1 and 2 (Stx1 and Stx2) with endothelial cells is an important step in the renal coagulation and thrombosis observed in hemolytic uremic syndrome. Previous studies have shown that bacterial lipopolysaccharide and host cytokines slowly sensitize en...
