In response to inflammatory stimuli, neutrophils migrate from the blood stream to infected tissues where they bind, engulf and inactivate microorganisms efficiently. Human neutrophil elastase (NE), a neutrophil granule component, is a key host defense protein that rapidly destroys virulence factors of ...
