[Metalloproteinases in the extracellular matrix: structure and activity].
The matrix metalloproteinases (MMP) are a multigenic family involving 14 enzymes which can cleave most, if not all, the components of the extracellular matrix (interstitium and basement membranes). The present work reports on the main structural characteristics, the substrate preference and the site synthesis of these proteinases and their inhibitors (TIMP). Human MMPs are produced by various cell types and are involved in the remodelling of the extracellular matrix in many physiological and pathophysiological circumstances. Elastolytic MMPs produced by monocytes and/or macrophages (matrilysin, gelatinases, macrophage elastase) are likely to be implicated in the development of acquired pulmonary emphysema.
