Figure 5From: Role of aberrant metalloproteinase activity in the pro-inflammatory phenotype of bronchial epithelium in COPDTIMP-2 levels are reduced in PBEC from COPD patients versus PBECs from the control groups. Cells were growth factor-deprived overnight and incubated for 24 hrs in A) absence and B) presence of CSE (2.5%). Absolute values and medians are shown. Significance is indicated (* = p < 0.05).Back to article page
