OBJECTIVE: To investigate the expression of peroxisome proliferator-activated receptor γ (PPAR-γ) in the sinus mucosa of chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP).
METHOD: Using immunohistochemistry and RT-PCR, testing the content of PPAR-γ in sinus mucosa and nasal polyps of patients with chronic sinusitis without nasal polyps and normal inferior turbinate, and analyzing the differences.
RESULT: The PPAR-γ was found both in sinus mucosa of CRSsNP, nasal polyps of CRSwNP and in normal inferior turbinate; (2) The expression of PPAR-γ in sinus mucosa of CRSsNP and nasal polyps of CRSwNP was lower than that in normal inferior turbinate tissue, and the differences was prominent in statistics; (3) No differences in the expression of PPAR-γ were obtained in sinus mucosa of CRSsNP and nasal polyps of CRSwNP.
CONCLUSION: The PPAR-γ expressed in human nasal mucosa, meanwhile it was descending in sinus mucosa of CRSsNP and nasal polyps of CRSwNP. The long-term inflammations resulted from CRSsNP and nasal polyps of CRSwNP might relate to PPAR-γ, it suggested that PPAR-γ agonists may offer a new therapy for the treatment of Chronic Rhinosinusitis.
