Inhibition of Cholera Toxin and Other AB Toxins by Polyphenolic Compounds.
PLoS ONE, 2016 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 ...

AB Toxins: A Paradigm Switch from Deadly to Desirable [PDF]
Toxins, 2010 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 ...

mBio, 2015 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 ...

Structure and function of a fungal AB toxin-like chimerolectin involved in anti-nematode defense. [PDF]
EMBO JABSTRACT Fungal defense against predators largely relies on protein toxins, many of which are lectins. We previously showed that the production of the nematotoxin CCTX2 is upregulated in the Agaricomycete Coprinopsis cinerea upon predation by nematodes.

Diphtheria and the AB Toxin Group
, 2023 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 ...

AB Toxins as High-Affinity Ligands for Cell Targeting in Cancer Therapy
International Journal of Molecular Sciences, 2023 Conventional targeted therapies for the treatment of cancer have limitations, including the development of acquired resistance. However, novel alternatives have emerged in the form of targeted therapies based on AB toxins. These biotoxins are a diverse group of highly poisonous molecules that show a nanomolar affinity for their target cell receptors ...

Characterizing RecA-Independent Induction of Shiga toxin2-encoding Phages by EDTA Treatment [PDF]
, 2012 The bacteriophage life cycle has an important role in Shiga toxin (Stx) expression. The induction of Shiga toxin-encoding phages (Stx phages) increases toxin production as a result of replication of the phage genome, and phage lysis of the host cell also
