MMP12, Lung Function, and COPD in High-Risk Populations
A variant of MMP12, encoding a matrix metallopeptidase, is associated with increased lung function in children with asthma and in adult smokers. It is also associated with a decreased risk of chronic obstructive pulmonary disease in adult smokers. A variant of MMP12 is associated with increased lung...

| Shrnutí: | A variant of
MMP12,
encoding a matrix metallopeptidase, is associated with increased lung function in children with asthma and in adult smokers. It is also associated with a decreased risk of chronic obstructive pulmonary disease in adult smokers.
A variant of
MMP12
is associated with increased lung function in children with asthma and in adult smokers. It is also associated with a decreased risk of chronic obstructive pulmonary disease in adult smokers.
MMP-12 (matrix metalloproteinase 12, also known as macrophage metalloelastase or matrix metallopeptidase 12 [Mmp12] in mice) is produced by macrophages, the predominant cell type that patrols the lower airspaces under normal conditions and the main inflammatory cell type that is recruited with smoking.
1
Mmp12 is essential for the development of emphysema in mice exposed to cigarette smoke,
2
including mice with increased expression of interleukin-13.
3
Increased expression of
MMP12
in the lower airways can lead to degradation of elastin, resulting in elastin fragments that can cause a positive feedback loop, further increasing macrophage recruitment in mice
4
and in cultured human cells. . . . |
