Scientists finally discover how a common gut bacterium can trigger colon cancer

For nearly two decades, scientists have known that a common gut bacterium can produce a toxin that damages the colon and helps drive the formation of tumors. What they could not explain was how the toxin first attaches to intestinal cells and begins its attack. Now, researchers have uncovered that missing step, revealing a surprising vulnerability that could lead to new ways of protecting the colon.
