Elastase

Elastase is an enzyme produced primarily by certain white blood cells, playing a key role in the body's immune response. Its main function is to break down proteins, especially elastin, a protein that gives elasticity to tissues like lungs and skin. This helps the body eliminate bacteria and damaged cells. However, excessive elastase activity can damage healthy tissues, contributing to conditions like emphysema or pancreatitis. Detecting elastase levels can aid in diagnosing and monitoring these diseases. Overall, elastase is crucial for immune defense and tissue maintenance but needs balanced regulation to prevent tissue damage.
