Abstract
BackgroundMatrix metalloproteinase (MMP)-7 was reported to be a key molecule in the pathogenesis of idiopathic pulmonary fibrosis (IPF) based on the result of microarray analysis and knockout mice. However, the role of MMP-7 has not been determined in other types of idiopathic interstitial pneumonia (IIP). The aim of this study is to investigate the role of MMP-7 in IIP by comparing its expression in UIP and cryptogenic organizing pneumonia (COP).
MethodsMMP and TIMP levels in bronchoalveolar lavage (BAL) fluid and their expression on lung tissues were compared between normal control (n=5) and the patients with IPF (n=6) and COP (n=11).
ResultsThere was no significant difference in BAL fluid MMP-7 level between UIP and COP, although it was higher in both diseases compared to normal control. Furthermore, the pattern and the degree of MMP-7 expression in lung tissues were also similar in both IPF and COP. Whereas MMP-2 level was higher in COP and MMP-9 was higher in IPF.
ConclusionMMP-7 seems to play an important role in the pathogenesis of not only IPF but also COP; therefore it may not be the key factor determining the prognosis or reversibility of IIPs.
