【Abstract】Objective To study the regulatory ability of peroxisome proliferatoractivated receptor γ(PPARγ) ligands to the inflammatory response in human gallbladder epithelial cells.
Methods Culture human gallbladder epithelial cells and identify them . Cells were treated for 24 hours with 0, 10 μmol/L, 20 μmol/L, 30 μmol/L, 50 μmol/L and 100 μmol/L of Ciglitazone during cellular growth peak(5th day), then stimulated them with hIL-1β 5 ng/ml for 2 hours and measured the concentration of IL-6、IL-8 and TNF-α in cellular supernatants by riadioimmunoassay.
Results Contrasted with control group, the expression of IL-6 and IL-8 in each test group were inhibited (P<0.001). The IL-6 and IL-8 levels were gradually dropped and corelated with the dosage of Cigtitazone, and manifested dosagedependence (P<0.001). The concentration of TNF-α could not be measured.
Conclusion PPARγ ligands can inhibit the expression of IL-6 and IL-8 in human gallbladder epithelial cells and probably produce effect in the regulation of cholecystic inflammation.
