ABSTRACT To explore the expression of transforming growth factor beta receptor(TGFpR) I, II in the chronic rhinosinusitis, nasal polyps and normal nasal mucosa tissues.
The protein expression of the TGFbetaR I and TGFbetaR II were determined by means of immunohistochemistry in chronic rhinosinusitis tissues from 25 patients, nasal polyps tissues from 21 patients and inferior turbinate mucosa tissues from 17 patients with deviation of nasal septum.
(1) In chronic rhinosinusitis and nasal polyps tissues, compared with controls, the expression of TGFbetaR I and TGFbetaR II protein was increased significantly (P < 0.01). (2) The expression of TGFbetaR I and TGFbetaR II protein in nasal polyps tissues was significant increased than that in chronic rhinosinusitis tissues (P < 0.01).
The different expression level and pattern of TGFbetaR I and TGFbetaR II in chronic rhinosinusitis and nasal polyps tissues indicates TGFbetaR may play a different role in the pathogenesis chronic rhinosinusitis and nasal polyps.
