leukoprotease

leu·ko·pro·te·ase

(lū'kō-prō'tē-ās),
An ill-defined proteolytic enzyme product of polynuclear leukocytes, formed in an area of inflammation that liquefies dead tissue.

leukoprotease

Antiproteases such as [[alpha].sub.1]-proteinase inhibitor ([[alpha].sub.1]-PI) and secretory leukoprotease inhibitor may be inactivated by ROS.
Among the various trypsin inhibitors tested, the natural airway inhibitor, secretory leukoprotease inhibitor (SLPI), which is secreted from non-ciliated secretory airway Clara and goblet cells, (36),(37) and is found in bronchoalveolar lavage fluid and nasal and salivary secretion, efficiently suppresses proteolytic activation of IAV HA and viral multiplication.

These cathepsins have been reported to cleave and inactivate antiprotease secretory leukoprotease inhibitor (SLIP) of neutrophil-derived elastase, shifting delicate protease/antiprotease equilibrium toward proteolytic activity and increasing neutrophil extracellular trap (NET) formation and activity [39,40].
