In a recent study, scientists devised a way of reversing the buildup of compounds that lead to some age-related diseases.
The same chemical process that turns a baking cake golden brown is at work aging your body’s cells. Over decades, your tissues, baking steadily at 98.6 degrees, slowly accumulate compounds called advanced glycation end products, or AGEs, as sugars interact with protein and fat in the bloodstream. The buildup of AGEs is a hallmark of the aging process, making tissues like collagen sticky and rigid and causing inflammation that can lead to heart disease, eye damage, kidney disease and diabetes.
Researchers have tried unsuccessfully to develop medications that can stop AGEs from forming. But a new study, published on July 16 in the journal
Nature Communications, describes a different tack: Scientists created an enzyme that cleans one of the most common AGEs from human tissue, helping to turn back the clock even after the aging compounds have settled in the body. This cleanse can help repair the tissue and has the potential to allow cells to act younger.
“It’s a small step in this bigger direction, because aging is very complicated,” said Aaron Cravens, a founder and the chief executive of Revel Pharmaceuticals, which developed the new enzyme, and the lead author of the study. “It’s the first time, I think, that anyone in the field has shown at the structural level that you can actually reverse some of these changes.”
