Protein Research Provides Clues to How Blood Clots, Wounds Heal

They are proteins that cut other proteins, enabling a wide range of essential functions such as wound healing, blood clotting and formation of muscle and nerve cells.
But serine proteases also can cut a path of destruction, contributing to the plaques involved in heart disease and Alzheimer’s and to extensive birth defects as well when something goes awry. Understanding this sort of physiological crescendo called a protease cascade is a goal of Dr. Ellen K. LeMosy, developmental biologist at the Medical College of Georgia.
