Role of Matrix Metalloproteinases in Photoaging and Photocarcinogenesis
Matrix metalloproteinases (MMPs) are zinc-containing endopeptidases with an extensive range of substrate specificities. Collectively, these enzymes are able to degrade various components of extracellular matrix (ECM) proteins. Based on their structure and substrate specificity, they can be categorized into five main subgroups, namely (1) collagenases (MMP-1, MMP-8 and MMP-13); (2) gelatinases (...
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...
متن کاملIncreased expression of matrix metalloproteinases and matrix degrading activity in vulnerable regions of human atherosclerotic plaques.
Dysregulated extracellular matrix (ECM) metabolism may contribute to vascular remodeling during the development and complication of human atherosclerotic lesions. We investigated the expression of matrix metalloproteinases (MMPs), a family of enzymes that degrade ECM components in human atherosclerotic plaques (n = 30) and in uninvolved arterial specimens (n = 11). We studied members of all thr...
متن کاملMatrix metalloproteinase 12-deficiency augments extracellular matrix degrading metalloproteinases and attenuates IL-13-dependent fibrosis.
Infection with the parasitic helminth Schistosoma mansoni causes significant liver fibrosis and extracellular matrix (ECM) remodeling. Matrix metalloproteinases (MMP) are important regulators of the ECM by regulating cellular inflammation, extracellular matrix deposition, and tissue reorganization. MMP12 is a macrophage-secreted elastase that is highly induced in the liver and lung in response ...
متن کاملMatrix metalloproteinases
What makes an MMP an MMP? They all have a conserved zinc-binding site in their catalytic domain (HEXGHXXGXXH), and the sequence PRCGVPD in the propeptide domain. The cysteine residue serves to anchor the propeptide to the catalytic zinc, suppressing enzymatic activity in a manner that is not unlike a thumb in an open mouth. Release of this interaction results in proteolytic activity. MMPs are a...
