TIMP-1 | a major fibrogenic effector in lungs. Indeed, upon fibrogenic stimuli, large amounts of TIMP-1 in the remodeling tissue are believed to contribute to the creation of a non-degrading environment, leading to the alteration of protease-anti-protease balance, extracellular matrix accumulation, and tissue fibrosis. MMP-12 deficiency does not seem to be involved in TIMP-1 regulation | Mus musculus |

General Information | Comment | Organism |
---|---|---|
physiological function | macrophage elastase is able to degrade extracellular matrix components such as elastin and is involved in tissue remodeling in inflammatory respiratory diseases such as chronic obstructive pulmonary diseases, including emphysema. MMP-12 is also involved in asthma and fibrosis. Inhibitors demonstrate a reduction in both the inflammatory process and airspace enlargement in lung tissue. MMP-12 plays a predominant role in the inflammatory process induced by cigarette smoke | Homo sapiens |
