Researchers have discovered that a protein called fibulin-5 plays a vital role in maintaining the elasticity of the skin, blood vessels, and lungs. Scientists from the University of Texas Southwestern Medical Center and the University of California found that mice bred to lack the protein developed loose saggy skin, emphysema, and blood vessel abnormalities. The findings suggest that fibulin-5 could help scientists to develop methods of regenerating elastic fibers. Such technology could help in the prevention of diseases like emphysema as well as having a cosmetic use for the prevention of wrinkles and other signs of aging.
