Shiga toxin binds to activated platelets [PDF]

Journal of Thrombosis and Haemostasis, 2004
Hemolytic uremic syndrome (HUS) is associated with acute renal failure in children and can be caused by Shiga toxin (Stx)-producing Escherichia coli. Thrombocytopenia and formation of renal thrombi are characteristic of HUS, suggesting that platelet activation is involved in its pathogenesis. However, whether Shiga toxin directly activates platelets is

Altruism of Shiga toxin-producing Escherichia coli: recent hypothesis versus experimental results

Frontiers in Cellular and Infection Microbiology, 2013
Shiga toxin-producing Escherichia coli (STEC) may cause bloody diarrhea and hemorrhagic colitis, with subsequent systemic disease. Since genes coding for Shiga toxins (stx genes) are located on lambdoid prophages, their effective production occurs only ...

Hemolytic uremic syndrome related to Shiga-like toxin-producing Escherichia coli with encephalitis hiding a human herpesvirus-6 infection: a case report

Journal of Medical Case Reports, 2021
Background Cardiac and neurological involvement in hemolytic uremic syndrome are life-threatening complications. The most frequent complications of cardiac involvement in hemolytic uremic syndrome are myocarditis and cardiac dysfunction due to fluid ...

Role of Recent Therapeutic Applications and the Infection Strategies of Shiga Toxin-Producing Escherichia coli

Frontiers in Cellular and Infection Microbiology, 2021
Shiga toxin-producing Escherichia coli (STEC) is a global foodborne bacterial pathogen that is often accountable for colon disorder or distress. STEC commonly induces severe diarrhea in hosts but can cause critical illnesses due to the Shiga toxin ...

Multi‐omics biomarkers for intestinal infection and inflammation in inflammatory bowel disease: Current evidence, translational challenges, and diagnostic opportunities

Interdisciplinary Medicine, EarlyView.
Prospective multi‐site cohorts, multi‐omics profiling, and computational analysis may help identify biomarker patterns across clinical settings in IBD and superimposed infections. With further mechanistic and clinical validation, these signals could support the development of practical multi‐analyte tools for more precise diagnosis and management ...

How ricin and shiga toxin reach the cytosol of target cells : retrotranslocation from the endoplasmic reticulum [PDF]

, 2012
A number of protein toxins bind at the surface of mammalian cells and after endocytosis traffic to the endoplasmic reticulum, where the toxic A chains are liberated from the holotoxin.

Tamoxifen blocks retrograde trafficking of Shiga toxin 1 and 2 and protects against lethal toxicosis

Life Science Alliance, 2019
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–

Targeting the intratumoral microbiota to overcome cancer immunotherapy resistance

Interdisciplinary Medicine, EarlyView.
This review delineates the mechanisms of intratumoral microbiota in cancer immunotherapy resistance, and offers strategies for microbiota‐targeted precision immunotherapy. Abstract Cancer remains a significant global health threat. The tumor microenvironment (TME) is a sophisticated ecological niche that exerts a pivotal effect on treatment outcomes ...

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

TOXINS AND ANTITOXINS OF BACILLUS DYSENTERIÆ SHIGA [PDF]

Journal of Experimental Medicine, 1920
With the methods which have been described we have separated an exotoxin and an endotoxin from cultures of the Shiga dysenteric bacillus. The study of the nature and effect of the poison of this microorganism is thus simplified. The two toxins are physically and biologically distinct.
