Elastin degradation by matrix metalloproteinases. Cleavage site specificity and mechanisms of elastolysis.
Insoluble elastin was used as a substrate to characterize the peptide bond specificities of human (HME) and mouse macrophage elastase (MME) and to compare these enzymes with other mammalian metalloproteinases and serine elastases. New amino termini detected by protein sequence analysis in insoluble elastin following proteolytic digestion reveal the P'1 residues in the carboxyl-terminal directio...
متن کاملElastin degradation and calcification in an abdominal aorta injury model: role of matrix metalloproteinases.
BACKGROUND Elastin calcification is a widespread feature of vascular pathology, and circumstantial evidence exists for a correlation between elastin degradation and calcification. We hypothesized that matrix metalloproteinase (MMP)-mediated vascular remodeling plays a significant role in elastin calcification. METHODS AND RESULTS In the present studies, we determined that short-term periadven...
متن کاملFibrillin degradation by matrix metalloproteinases: implications for connective tissue remodelling.
Fibrillin is the principal structural component of the 10-12 nm diameter elastic microfibrils of the extracellular matrix. We have previously shown that both fibrillin molecules and assembled microfibrils are susceptible to degradation by serine proteases. In this study, we have investigated the potential catabolic effects of six matrix metalloproteinases (MMP-2, MMP-3, MMP-9, MMP-12, MMP-13 an...
متن کاملDentin matrix degradation by host matrix metalloproteinases: inhibition and clinical perspectives toward regeneration
Bacterial enzymes have long been considered solely accountable for the degradation of the dentin matrix during the carious process. However, the emerging literature suggests that host-derived enzymes, and in particular the matrix metalloproteinases (MMPs) contained in dentin and saliva can play a major role in this process by their ability to degrade the dentin matrix from within. These finding...
متن کاملP 88: Matrix Metalloproteinases in Neuroinflammation
Matrix metalloproteinases (MMPs) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. MMPs have been demonstrated to increase the permeability of the blood–brain barrier (BBB) by degrading the c...
