Structure of the Diphtheria Toxin at Acidic pH: Implications for the Conformational Switching of the Translocation Domain

open access: yesToxins, 2020
Diphtheria toxin, an exotoxin secreted by Corynebacterium that causes disease in humans by inhibiting protein synthesis, enters the cell via receptor-mediated endocytosis. The subsequent endosomal acidification triggers a series of conformational changes,

N-terminus of flagellin enhances vaccine efficacy against Actinobacillus pleuropneumoniae

open access: yesBMC Veterinary Research, 2022
Background Flagellin elicits potent immune response and may serve as a vaccine adjuvant. We previously reported that the N-terminus of flagellin (residues 1–99, nFliC) is sufficient for vaccine efficacy enhancement against Pasteurella multocida challenge

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]

open access: yes, 2018
Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

Riboflavin: The Health Benefits of a Forgotten Natural Vitamin [PDF]

open access: yes, 2020
Riboflavin (RF) is a water-soluble member of the B-vitamin family. Sufficient dietary and supplemental RF intake appears to have a protective effect on various medical conditions such as sepsis, ischemia etc., while it also contributes to the reduction ...

Staphylococcal exotoxin superantigens induce human immunodeficiency virus type 1 expression in naturally infected CD4+ T cells [PDF]

open access: yesJournal of Virology, 1992
A high proportion of Staphylococcus aureus strains of human origin produce one or more exotoxins. In vivo, these toxins may give rise to a variety of clinical syndromes. In vitro, staphylococcal exotoxins have been shown to bind both to human leukocyte antigen (HLA) class II molecules on antigen-presenting cells and to the T-cell receptors on large ...

Molecular cloning and expression of novel fibroblast growth factor-2 conjugated with immunodominant domains of pseudomonas exotoxin [PDF]

open access: yes, 2015
Angiogenesis is very important in cancer growth and metastasis. Basic fibroblast growth factor (bFGF) as one of the most important angiogenesis factors is an attractive target for cancer vaccine.

Induction of murine cytolytic T lymphocytes by Pseudomonas aeruginosa exotoxin A [PDF]

open access: yesInfection and Immunity, 1988
Pseudomonas aeruginosa exotoxin A (PA), a potent protein synthesis inhibitor, was found to be a weak T-cell mitogen for murine splenocytes. Maximal stimulation of [3H]thymidine incorporation was obtained with 10 to 100 ng of toxin per ml following a 4-day induction.

Cholera Toxin Promotes Th17 Cell Differentiation by Modulating Expression of Polarizing Cytokines and the Antigen-Presenting Potential of Dendritic Cells. [PDF]

open access: yesPLoS ONE, 2016
Cholera toxin (CT), an exotoxin produced by Vibrio cholera, acts as a mucosal adjuvant. In a previous study, we showed that CT skews differentiation of CD4 T cells to IL-17-producing Th17 cells. Here, we found that intranasal administration of CT induced

Phase I clinical study of the recombinant antibody toxin scFv(FRP5)-ETA specific for the ErbB2/HER2 receptor in patients with advanced solid malignomas [PDF]

open access: yes, 2005
Introduction: ScFv(FRP5)-ETA is a recombinant antibody toxin with binding specificity for ErbB2 (HER2). It consists of an N-terminal single-chain antibody fragment (scFv), genetically linked to truncated Pseudomonas exotoxin A (ETA).

"Alternative" endocytic mechanisms exploited by pathogens: new avenues for therapeutic delivery? [PDF]

open access: yes, 2007
Some pathogens utilize unique routes to enter cells that may evade the intracellular barriers encountered by the typical clathrin-mediated endocytic pathway.
