Stomach tissue infected with Helicobacter pylori. (IMAGE)
Caption
Stomach tissue infected with Helicobacter pylori. What starts off as a repair response, transitions into a chronic condition after years of infection and creates the preconditions for precancerous lesions. The mucus-producing surface cells are stained red. The active signaling pathway, which induces rapid tissue growth, is shown in white. In a healthy stomach, this function is almost completely shut down.
