Description générale

Elastase, a glycoprotein, is a member of the serine proteases family. It is synthesized by human polymorphonuclear (PMN) leukocytes or by the pancreas. Human granulocyte elastase is liberated in large amounts from granulocytes in chronic inflammatory joint disorders.

Actions biochimiques/physiologiques

Elastase is a catalytic enzyme that catalyzes the cleavage of carboxyl groups on tiny hydrophobic amino acids including glycine, alanine, and valine. Its main function is to break down elastin. Free elastase in some purulent synovial fluids plays a key role in articular cartilage breakdown. Increased elastase levels in the plasma have been seen in patients with evident rheumatoid arthritis.
Elastase(s) can be assayed and differentiated using chromogenic and fluorogenic Pro-Val peptide substrates such as Glp-Pro-Val-pNA and MeOSuc-Ala-Ala-Pro-Val-4-MNA.

Human granulocyte elastase (EC 3.4.21.37) is released from granulocytes in large amounts in chronic inflammatory joint diseases and is therefore of special pathogenic and diagnostic importance. In order to examine the diagnostic significance of this enzyme as a clinico-chemical parameter

An assessment of elastase-substrate kinetics and adsorption at the solid-liquid interface of peptide-bound resin was made in an approach to the solid-phase detection of human neutrophil elastase (HNE), which is found in high concentration in chronic wound fluid.

G Dent et al.
Lung, 173(3), 165-175 (1995-01-01)
Elastase and antielastase activities were measured in bronchoalveolar lavage fluid (BALF) and their relationship to bronchoalveolar lavage (BAL) neutrophil numbers was assessed in order to determine whether the elevated BAL neutrophil count can predict a shift in the elastase/antielastase balance.
