🧬 How does a foodborne toxin punch holes in our cells?
This study unveils the first comprehensive structural models of the Clostridium perfringens enterotoxin (CPE)–claudin complex — shedding light on how this foodborne pathogen forms lethal pores in intestinal cells and disrupts epithelial integrity.
By combining AlphaFold2 multimer predictions and molecular dynamics simulations, the researchers propose a detailed mechanism of pore assembly, cation selectivity, and membrane anchoring, advancing our molecular understanding of toxin-mediated cell damage.
