The protease-antiprotease theory of emphysema is widely accepted, but exactly which cells/proteases play a role continues to be a controversial subject.Reports in humans show increased metalloproteinase activity in emphysema, but the exact role of metalloproteinases remains unclear.

Scandinavian Journal of Clinical and Laboratory Investigation, 1992
The Aspartic proteases (EC 3.4.23) are a group of proteolytic enzymes that share the same catalytic apparatus. Members of the aspartic protease family can be found in different organisms, ranging from humans to plants and retroviruses. The best known sources of aspartic proteases are the stomach of mammals, yeast and fungi, with porcine pepsin as the ...

Essays in Biochemistry, 2002 A protease can be defined as an enzyme that hydrolyses peptide bonds. Proteases can be divided into endopeptidases, which cleave internal peptide bonds in substrates, and exopeptidases, which cleave the terminal peptide bonds. Exopeptidases can be further subdivided into aminopeptidases and carboxypeptidases.

Lung Proteases and Protease Inhibitors
1977Homogenates of guinea pig lung show significant protease activity at pH values from 2.2 to 9.9. Perfusion results in increased activity in both acid and alkaline ranges. Protease activity can be extracted by repeated homogenization and sonication of the pellet.

Experientia, 1996
The interleukin-1 beta-converting enzyme (ICE)-like family proteases have recently been identified as key enzymes in apoptotic cell death. Among these proteases one can identify specific activities which may be involved in cytokine production or in resident protein cleavage. Several factors influence the constitutive apoptotic mechanism and may provide

Proteases and Protease Inhibitors in Neoplasia
1974Although proteases in tumours have been studied for many years [1], their role is far from clear. From a number of comparative studies (summarized in Table 1), however, it can be safely concluded that increased proteolytic activity is often associated with tumours.
