Scientists Track How H2O2 Keeps Cells Healthy

bacteriaIn a report out of Winston Salem, MA, scientists say claim to have figured out how hydrogen peroxide is produced in the human body to assist in keeping cells healthy when bacteria levels elevate.

“The report by a team of researchers at Wake Forest University School of Medicine, published in the journal Nature, said large amounts of hydrogen peroxide are produced when the immune system is activated in response to bacteria.

The team used X-ray crystallography to create a three-dimensional snapshot of how the proteins interact.

Scientists said a molecule known as peroxiredoxin (Prx) helps control levels of hydrogen peroxide. If levels of hydrogen peroxide become too high, the cell’s DNA and other proteins can be damaged.

“It basically acts as a sensor and warns the cell that levels are too high and that the cell needs to respond,” lead author Thomas J. Jonsson said in a news release. “Once that threat is gone, Prx needs to go back to its normal state.”

Prx becomes active again by binding with a protein known as sulfiredoxin, the report said.”

Remarkably, these complex processes in our own bodies can produce, balance and even perfectly control the levels of H2O2 in our own cells to maintain a healthy internal environment.

If only we were as clever as our own cells when it comes to healthy external environments! Surely we are beginning to see how all natural processes work together to maintain balance. The more we learn, the better able we will be at extending these lessons outward into the world of our human activities and processes.
