Immunopharmacology Comments
Neutrophil elastase (NE) is a serine proteinase with broad substrate specificity. It is stored in azurophil granules within neutrophils and is involved primarily in host defence. However, in addition to attacking proteins on invading microorganisms, secreted NE also hydrolyzes proteins of the host extracellular matrix, such as collagen-IV and elastin, hence its role in degenerative and inflammatory diseases. NE functions as a promoter of γδ T cell activation via a protease-activated receptor (PAR1)-dependent mechanism [5].
