Researchers uncover how bacterial toxin damages colon lining cells to trigger cancer

https://www.news-medical.net/news/20260508/Researchers-uncover-how-bacterial-toxin-damages-colon-lining-cells-to-trigger-cancer.aspx Since a landmark 2009 study, researchers have known that a common gut bacterium, Bacteroides fragilis, drives colon tumor formation, potentially leading to colorectal cancer, by secreting a toxin that damages the lining of the colon. But until now, the exact mechanism the toxin uses to latch onto those cells remained a mystery.
