Expression of CEACAM1 after IFN-γ stimulation in HBE cells. mRNA expression of CEACAM1 (a), CEACAM1-4L (b), CEACAM1-4S (c), CEACAM1-3L (d), CEACAM1-3S (e), CEACAM1-3 (f), as well as protein levels of CEACAM1 protein (g) were measured in HBE cells treated with vehicle (control) or with IFN-γ at concentration of 0, 1, 10 ng/ml for 24 h. Dynamic expression of CEACAM1 gene in HBE cells 0, 3, 6, 12, 24, 48, 72 h after treatment with vehicle (control) or with IFN-γ at 10 ng/ml (h). *, **, ***p-values less than 0.05, 0.01 and 0.005, as compared to control
