Description: A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology have shown that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.Contact with stomach acid keeps the mucin lining the epithelial cell layer in a spongy gel-like state. This consistency is impermeable to the bacterium Heliobacter pylori. However, the bacterium releases urease which neutralizes the stomach acid. This causes the mucin to liquefy, and the bacterium can swim right through it. Read more about this research.

Description: English: One mechanism H. pylori has to combat the acidic environment of the stomach is the urease enzyme. This enzyme can be found on the surface of and inside the cell. It takes urea and water from the bloodstream and stomach and converts them to ammonia and carbon dioxide. These products neutralize the strong acid of the stomach, and as a result a buffer zone surrounds the bacteria to protect it from the strong acids in its environment. Date: 20 November 2016.
