Abstract/OtherAbstract:
|
Nasal polyposis (NP), a chronic inflammatory disease of the upper airway, is a subgroup of chronic rhinosinusitis (CRS). Matrix metallo-proteinases (MMPs) and their tissue inhibitors (TIMPs) are considered to play important roles in the pathogenesis of nasal polyposis. The aim of the current study was to evaluate and compare the levels of MMP-1, MMP-2, MMP-8 and TIMP-2 in NP and CRS with normal nasal mucosa by using immunohistochemistry. Twenty-five patients with NP and fifteen patients with CRS underwent endoscopic sinus surgery. Diseased mucosal samples were obtained from ethmoidal sinuses. Control nasal mucosa (n=10) was obtained from inferior nasal turbinate. Immunohistochemistry for MMP-1, MMP-2, MMP-8 and TIMP-2 was performed. The expression of MMP-1, MMP-2 and MMP-8 significantly increased in NP and CRS compared with control (p<0.05). The distribution of TIMP-2 was higher in CRS than control and NP respectively (p<0.05). MMP-1 immunoreactivity was distributed in the extracellular matrix whereas MMP-2, MMP-8 and TIMP-2 immunostaining was present in the epithelium, submucosal glands, vascular endothelium and inflammatory cells in CRS and NP. We suggest that differences in histological features between CRS and NP might be related to the expression of MMP-1, MMP-2, MMP-8 and their tissue inhibitor-2. |
