Inhibition of Cholera Toxin and Other AB Toxins by Polyphenolic Compounds.
Cholera toxin (CT) is an AB-type protein toxin that contains a catalytic A1 subunit, an A2 linker, and a cell-binding B homopentamer. The CT holotoxin is released into the extracellular environment, but CTA1 attacks a target within the cytosol of a host ...

The macrophage response to planktonic Staphylococcus aureus involves the induction of proinflammatory microbicidal activity. However, S. aureus biofilms can interfere with these responses in part by polarizing macrophages toward an anti-inflammatory ...

Toxin Instability and Its Role in Toxin Translocation from the Endoplasmic Reticulum to the Cytosol
AB toxins enter a host cell by receptor-mediated endocytosis. The catalytic A chain then crosses the endosome or endoplasmic reticulum (ER) membrane to reach its cytosolic target. Dissociation of the A chain from the cell-binding B chain occurs before or

AIP56, an AB toxin secreted by <i>Photobacterium damselae</i> subsp. <i>piscicida</i>, has tropism for myeloid cells. [PDF]
Abstract The AB-type toxin AIP56 is a key virulence factor of Photobacterium damselae subsp. piscicida ( Phdp ), inducing apoptosis in fish immune cells.

Pet, a Non-AB Toxin, Is Transported and Translocated into Epithelial Cells by a Retrograde Trafficking Pathway [PDF]
ABSTRACT The plasmid-encoded toxin (Pet) of enteroaggregative Escherichia coli is a 104-kDa autotransporter protein that exhibits proteolytic activity against the actin-binding protein α-fodrin. Intracellular cleavage of epithelial fodrin by Pet disrupts the actin cytoskeleton, causing both cytotoxic and ...

AB Toxins: A Paradigm Switch from Deadly to Desirable [PDF]
To ensure their survival, a number of bacterial and plant species have evolved a common strategy to capture energy from other biological systems. Being imperfect pathogens, organisms synthesizing multi-subunit AB toxins are responsible for the mortality ...

The bacterium Clostridium botulinum, well-known for producing botulinum neurotoxins, which cause the severe paralytic illness known as botulism, produces C2 toxin, a binary AB-toxin with ADP-ribosyltranferase activity.

Type II toxin-antitoxin (TA) systems are the particular type of TA modules which take part in different kinds of cellular actions, such as biofilm formation, persistence, stress endurance, defense of the bacterial cell against multiple phage attacks, plasmid maintenance, and programmed cell death in favor of bacterial population.

Diphtheria and the AB Toxin Group
AB toxins have historically been associated with significant morbidity, mortality through infections such as botulinum, anthrax, cholera, and diphtheria. These AB toxin-mediated diseases remain prevalent in low and middle income countries, with intermittent outbreaks of Shiga toxin-producing Escherichia coli (STEC) or whooping cough by Bordetella ...
