Researchers Identify Mechanism of Bacterial Toxin in Colon Cancer Development
A team of researchers from Johns Hopkins University has discovered how the bacterial toxin BFT from Bacteroides fragilis damages colon lining cells, potentially leading to colorectal cancer. The study, published in Nature, reveals that BFT binds to the host receptor claudin-4, which is crucial for the toxin's ability to cause damage. This discovery has led to the development of a molecular decoy that successfully blocked the toxin's effects in animal models, offering a potential strategy for preventing colon damage and cancer.
