Calling All White Blood Cells

By Stephanie Pappas
ScienceNOW Daily News

Anyone who has felt the sting as hydrogen peroxide foams and fizzes on a scraped knee knows about the compound's antiseptic properties. But new research suggests that hydrogen peroxide does more than just kill microbes. It may also call for reinforcements, summoning an army of bacteria-fighting cells to cuts and wounds.

Next, the team used genetic manipulation to pinpoint the enzyme responsible for producing hydrogen peroxide. The culprit, a protein known as duox, is also found in the thyroid, digestive tract, and lungs of humans. Asthma and other disorders result from excessive inflammation in these tissues, so duox may play a role in those conditions, the researchers report tomorrow in Nature.
