Differential entry of botulinum neurotoxin A into neuronal and intestinal cells

A Couesnon, T Shimizu, MR Popoff - Cellular microbiology, 2009 - Wiley Online Library
Botulinum neurotoxins (BoNTs) are often acquired from the digestive tract and specifically

C Connan, C Varela‐Chavez, C Mazuet… - Cellular …, 2016 - Wiley Online Library
Botulinum neurotoxins (BoNTs) are responsible for severe flaccid paralysis (botulism), which

A novel function of botulinum toxin-associated proteins: HA proteins disrupt intestinal epithelial barrier to increase toxin absorption

Y Fujinaga, T Matsumura, Y Jin, Y Takegahara… - Toxicon, 2009 - Elsevier
Food-borne botulinum neurotoxin (BoNT) in the gastrointestinal lumen must cross an
epithelial barrier to reach peripheral nerves to mediate its toxicity. The detailed mechanism …

Translocation and dissemination of botulinum neurotoxin from the intestinal tract

Y Fujinaga, MR Popoff - Toxicon, 2018 - Elsevier
Botulinum neurotoxins (BoNTs) are potent toxins which induce flaccid paralysis by inhibiting
the release of acetylcholine at the neuromuscular junctions. They associate with non-toxic …

T Matsumura, Y Jin, Y Kabumoto… - Cellular …, 2008 - Wiley Online Library
The type B botulinum neurotoxin (BoNT) elicits flaccid paralysis and death in humans by
intoxicating peripheral nerves after oral absorption. Here, we examine the function of the …

Receptor‐mediated transcytosis of botulinum neurotoxin A through intestinal cell monolayers

A Couesnon, Y Pereira, MR Popoff - Cellular microbiology, 2008 - Wiley Online Library
Botulism is mainly acquired by the oral route, and botulinum neurotoxin (BoNT) escapes the
gastrointestinal tract by crossing the digestive epithelial barrier prior to gaining access to the …
